Egg tray equipment recycling resources

  A fully automatic egg tray machine is better, can produce all kinds of waste paper as egg tray, recycle resources, and is safe without wasting resources. The current egg tray machine is a new type of egg tray equipment, which is more energy-efficient in function and materials used Common egg tray machines include: large, medium and small egg tray machines, semi-automatic egg tray machines and fully automatic egg tray machines. Generally, the egg tray machines we produce now are fully automatic egg tray machines. The use of the egg tray machine can bring us many benefits because most of the raw materials of the egg tray are from unused waste paper, which is rich in resources and low in price. At the same time, it can increase waste utilization and when the egg tray is in use After it is finished, it can be decomposed by itself without polluting the environment.

    As a forming mold placed on the main body of the egg tray machine, the egg tray mold needs attention in the egg tray machine production line. Eggs have a certain size, and the egg tray mold is designed according to the size of the egg to ensure that the egg tray produced meets the size of the egg. A good egg tray mold can guarantee the quality of the egg tray and reduce the defective rate.

    Egg trays produced by egg tray equipment do not have special requirements for hot pressing. At present, the technology of Shuliy's egg tray production line is very skilled, and the precision of the mold is also very high. The products produced do not undergo heat pressing and shaping, but also fully satisfy domestic customers. Demand. For customers with higher product quality requirements, the product quality will be better after hot pressing.

    Pulp egg trays are mostly made from recycled paper pulp and pressed by forming machines. Because of its simple manufacturing process, low cost, and no environmental pollution, it is called "green" packaging and is the most common type of egg tray in our daily life. Plastic egg trays use plastic as the material, but produce colorful and beautifully shaped egg trays. Because of its high cost, it is generally used in high-end supermarkets.

    There are several directions that need to be paid attention to in the inspection of the automatic egg tray machine: safety is the first element in all industries and should not be ignored. Whether the mechanical operation is normal and the circuit installation is reasonable. Automated machinery production is smooth, equipment is regularly checked, and uncertainties are resolved first. Egg tray machine belongs to assembly line work, all links should be synchronized and accurate, and there should be no mistakes. This needs to be corrected slowly to meet your own ideal requirements. The control system must be selected well, with long service life and stable work.

The egg tray equipment production line is designed with a wastewater return system, that is to say, the wastewater generated in the production process of the host is returned to our pulping system through the wastewater return system, and our wastewater is recycled again. Then, during the operation of the entire production line, wastewater is continuously reused, so as to achieve complete no wastewater pollution.

    In the pulping system of the egg tray production line, we inject the tax into the beating machine, after the beating machine fully crushes the waste paper, the pulp is adjusted and the ratio of the pulp concentration in the pulping tank, and then directly by the host system Adsorption molding. After molding, a large amount of wastewater will be generated. At this time, we will introduce the wastewater into the beater again through the wastewater recovery system, and repeat the beating, pulping, and blending again and again and again. , Which reduces our use of water and fully recycles wastewater again, without causing pollution to the environment

    Mold design and production of egg tray production line This is an important part of the appearance and stiffness of egg tray products. The quality of the appearance depends on the design of the mold. Since the appearance scale of the egg tray is based on the mold, we are in mold design and During the production process, we must not carelessly, if there is any doubt about the mold, then the subsequent production cannot be carried out. Therefore, in the selection of materials and casting, we need to work hard. This is also an important reason why the cost of egg tray commodity molds remains high. This part of pulping is very simple for commodities that do not need to add other additives or do not need to adjust the pulp, but this step is also very important if you want to add additives or need to adjust the pulp.

    This link is relatively simple to control compared to the previous two links. The main reason is to control its temperature not to be too high, but the conditions require a good drying design. It is mainly dried. The Shuliy egg tray machine uses hot air to dry, the newly formed or wet egg tray is sent to the long drying tunnel, and moves slowly on the conveyor belt, feeling the hot air from all directions. These hot winds formally help them to handle After removing the water, all the procedures for producing egg trays are completed in a moment.

    The egg tray production line is a kind of waste paper recycling line that uses various waste papers as raw materials, and after processing and production of the production line, the waste paper is directly converted into products. During the operation of the entire production line, no wastewater is generated. There is no air pollution. The waste paper recycling and reuse project, egg tray production line will be widely popularized in industrial production.

The product cost provided by the equipment manufacturer in the equipment manual is generally only for reference. Because the cost calculation provided by some equipment manufacturers often ignores the actual utilization rate of the equipment, it does not strictly calculate the loss rate of slurry and additives and does not strictly assess the impact of factors such as product qualification rate on the cost, but it is fully calculated, so and The actual cost does not exactly match.

For example, the utilization rate of the slurry (including additives) is not 100% in the production process. If the loss of slurry and additives (loss in the wet end process) is considered, a meal of 25 grams can be produced without a ton of dry slurry. Boxes of 40,000 are calculated based on the 95% slurry utilization rate, but 38,000. If you consider the 95% pass rate, 38,000 will become 36,100. With this item alone, the cost of the product differs by nearly 10%. If the utilization rate of the equipment can no longer meet the requirements, then the product cost and economic benefits will be farther away.

Precautions for the use of egg tray machine equipment molds: remember to lubricate the molds before use to minimize the friction of each mold operation and extend the service life. Before the machine is stopped, it is forbidden to directly touch the mold with your hands to prevent people from being injured. Use special clamps to pick and place products and reduce work. When not in production, the mold of the egg tray equipment should be cleaned of the debris in the mold cavity, and then coated with anti-rust oil. Regularly check and measure the size of the mold, record the data, and do mold loss analysis to control the quality of the product within the qualified range.

    Except for the cutters, die-cutting dies are made of ordinary carbon steel; setting dies and shaping dies are usually made of brass, aluminum alloy and stainless steel. The forming mold is currently made of brass, aluminum alloy and resin. When it is used in industrial packaging products with low precision, it can be directly manufactured by casting. Those with high precision must be manufactured by mechanical cutting. The transfer mold in the forming mold is preferably manufactured by directly overturning the resin from the corresponding punch or concave mold with high precision. If there is a paper sample, a low melting point alloy can be used to directly overturn the mold using the sample as a master mold.

    The composition of the cost of paper-molded packaging products also has in common with general products, such as materials, energy consumption, wages, rent, water charges, electricity costs, transportation costs, depreciation costs, start-up fees, office fees, operating expenses, working capital loans Interest, etc., we can estimate the cost price per unit weight of the product based on the relevant elements listed above and the approved output, but this is just a statistic and does not truly reflect the cost of a product. Therefore, the quotation for a certain product cannot be based solely on the product weight. In the cost components, wages, rent, depreciation costs, start-up costs and food expenses of some enterprises are basically a fixed value, so the greater the output, the lower the cost. Therefore, the quotation for a certain product should consider the quantity of the order batch.

Compared with traditional cleaning methods, using dry ice cleaning is a more effective technique. This technology does not use abrasive media, but uses special hoses and nozzles to accelerate dry ice (solid CO2) at supersonic speed, and spray dry ice onto the surface to achieve rapid cleaning. Once dry ice hits the surface, the combination of the kinetic energy and thermal effect of the dry ice explosion will immediately remove the stain. Once affected, the carbon dioxide sublimation gas will return to the gaseous state, there will be no residue. As an example, cleaning the sand core box is usually done by spraying dry ice particles. Due to the very complex geometry, dry ice can provide accurate and consistent cleaning. Dry ice cleaning can greatly shorten the cleaning time (up to 60%), and reduce damage to the equipment to avoid the generation of waste. It allows non-conductive, in-situ methods to clean tooling and molds.

01, what is dry ice

Dry ice is solid carbon dioxide with low physical properties (-78.5 degrees Celsius) and easy sublimation. Mainly from the exhaust gas in industrial production. Carbon dioxide manufactured and recovered. It is extracted, liquefied, and transported. Then make solid dry ice. The morphology is granular, flake, and block.

02. What is dry ice cleaning

The dry ice washing machine sprays dry ice (solid carbon dioxide) onto the surface at supersonic speed. The dry ice sublimates instantly, producing an impact microburst effect. The stain is contracted by the cold, and the strong airwaves peel the stain from the surface of the workpiece to achieve cleaning. Completely solved the problem that the traditional cleaning method will damage the mold.

03, non-destructive cleaning of dry ice

The following is an experimental study of (Kettering University): Microscopic photographs of mold steel before and after being sprayed at a distance of 25mm and 90 ° vertical spray for 60 seconds:

Experimental conditions: The material was tested at an angle of 90 ° and 45 ° to the surface of the sample using a magic wand. Each angle was tested at 1 inch and 3 inches from the surface of the sample. Each material was tested for a duration of 30 seconds or 60 seconds for all variables. The material is subjected to full-size pellets, shaved pellets or shaved blocks. The variables that remain unchanged are as follows: air pressure at 75 psi, dry ice flow at the highest water level (level 6).

A similar experimental study by James Snide: Preliminary evaluation of dry ice cleaning, Materials & Process Associates, Inc. (October 12, 1992), which measured the thermal stress during dry ice cleaning. The study showed that a temperature reduction only occurred on the surface, not on the substrate There is an opportunity for thermal stress.

The flow of dry ice particles continuously sprayed the test sample for 30 seconds (a relatively long time in this process), and the thermocouple recorded the varying temperature at various depths. As shown in the figure below, the surface-mounted thermocouple records the temperature drop whenever the particle stream passes directly through it (50 degrees C, about 5 seconds). In contrast, thermocouples of various depths embedded in the substrate recorded a slow gradual temperature drop corresponding to the temperature drop across the test panel. After 30 seconds, the 2mm depth of the thermocouple fell only 10 degrees Celsius. This curve shows that the thermal effect only occurs on the surface of the stain and the tool mold base, and has no adverse effect on the mold.

The chemical structure is very stable, and it is not easy to react with the substances that need to be cleaned.


04. Advantages of dry ice cleaning

Non-destructive cleaning-prolongs the service life of products, molds and equipment

The term dry ice is no longer familiar to the compatriots in the gas industry, but for the dry ice washing machine, you must be as enthusiastic as the gas city jun to investigate its cause. So what exactly is a dry ice washer?

Dry ice washing machine

The dry ice washer is a type of washing machine. The cleaning system sprays the dry ice particles of the dry ice washer to the working surface to be cleaned through high-pressure air, and uses the physical reflection of the temperature difference to cause different substances to separate under different shrinking speeds. When the dry ice particles of -78 degrees Celsius touch the surface of the dirt, they will embrittle and explode, causing the dirt to shrink and loosen. The dry ice particles will instantly vaporize and expand by 800 times. The strong peeling force of the product will quickly remove the dirt. Completely detached from the surface of the object, so as to achieve a fast, efficient, safe and energy-saving cleaning effect. The carbon dioxide used for dry ice cleaning comes from industrial waste gas, high-altitude air separation, etc. Dry ice washing itself does not produce carbon dioxide. Nowadays, dry ice cleaning methods have been rapidly developed around the world.

Dry ice cleaning principle

Dry ice particles impact the surface to be cleaned at high speed under the action of compressed air, and the kinetic energy is converted into heat energy;

The surface dirt layer is quickly embrittled and burst by cold shock, which greatly reduces the adsorption force between it and the base layer;

Dry ice is crushed into dry ice particles at the moment of impact and enters the fissure of the dirt layer, and sublimates rapidly, and the volume expands by 800 times, so that the dirt layer is peeled off instantly to achieve the best cleaning effect;

Dry ice cleaning advantages

(1) Can be cleaned without disassembly: The machine can be cleaned without disassembly, and dry ice particles can enter every tiny corner.

(2) Short machine downtime: fast and efficient cleaning.

(3) Environmentally friendly cleaning: no chemical additives or abrasive blasting.

(4) The surface will not be destroyed.

(5) No residue: dry ice is completely converted into carbon dioxide gas, and there is no residue such as sandblasting abrasive or waste water.

The dry ice washing machine can accelerate dry ice particles with a diameter of 3mm to 150m / s by compressed air.

As a result, a high intermediate speed and an ultra-low temperature of -78.5 ° C are produced, and the dirt freezes and becomes brittle.

Dry ice cleaning and decontamination ability

Dirty, dirt accumulated on abrasive tools, parts and machines for a long time is usually difficult to clean.

Common problems: Residues will be left after sandblasting, such as sand or glass particles and other abrasive blasting abrasives, these residues usually need to be wiped off after cleaning. These problems will be solved once the dry ice washing machine is used. Dry ice cleaning The sprayed dry ice particles are converted into carbon dioxide, leaving only a clean surface.

Dry ice particles penetrate the cracks in the dirt and blow the dirt away from the surface. Therefore, when removing all kinds of dirt, dry ice cleaning will not damage the surface to be cleaned.

During the production of dry ice pellets, liquid carbon dioxide flows into the hopper in the pelletizer, and as a result of the pressure drop, it solidifies into dry ice and snow. Then it is compressed by a hydraulic cylinder, and after passing through the extrusion die, the cylindrical dry ice is extruded.

Dry ice cleaning scope: engine cleaning, petrochemical equipment cleaning, steel equipment cleaning, electric power equipment cleaning, printing machinery cleaning, casting mold cleaning, aviation equipment cleaning, food equipment cleaning.

Mold is an important tool used in the tire vulcanization process. During the use of the mold, the mold is inevitably contaminated by the comprehensive deposition of rubber, compounding agents, and mold release agents used in the vulcanization process (the main pollutants are sulfides, inorganic oxides, silicone oil, carbon black, etc.). Caused some patterns to pollute the dead zone. Therefore, the mold must be cleaned frequently to ensure the cleanliness of its surface, so as to ensure the quality of the tire and the life of the mold. In view of this, the development of tire mold cleaning technology has received much attention from the industry.

1. Traditional cleaning methods

There are two types of traditional cleaning methods for tire molds:

(1) Mechanical cleaning method

Using a manual abrasive cloth or steel wire physical grinding and dry sandblasting, different combinations can be selected for cleaning according to needs. The mechanical cleaning method is a mature technology widely used by the tire industry. This method has the advantages of being simple and easy to implement, and has low requirements on equipment and tools; but also has insurmountable defects: it can cause mechanical damage to the mold and shorten the life of the mold; sandblasting can easily block the exhaust hole of the mold, and clear the exhaust after sandblasting The work volume of the stomata is very large; the mold must be disassembled, resulting in high labor intensity and a long cleaning cycle.

(2) Chemical cleaning method

The chemical cleaning method mainly includes the organic solvent method, melting method, pickling method, alkaline washing method, etc.

These methods are easy to use and have low cost, but long-term use of the above methods will cause mold corrosion, which directly affects the appearance and quality of the product; at the same time, these pharmaceutical raw materials pollute the environment and damage the health of the operator, and must have complete labor protection methods and pollutants Processing equipment. At present, the law is mainly used for small rubber products enterprises.

With the continuous development of science and technology, some new technologies have been continuously developed and applied. These cleaning technologies will bring a "revolution" to the tire mold cleaning industry, which has attracted much attention. But whether these higher-invested technologies can be accepted by the market needs to be tested.

The following will focus on introducing several new technologies that have been industrialized.

2. New cleaning technology

(1) Laser cleaning technology

Laser cleaning technology is a new type of cleaning technology that has developed rapidly in the past 10 years. It has gradually replaced the traditional cleaning process in many fields with its own many advantages.

Laser cleaning technology refers to the use of high-energy laser beam to irradiate the surface of the workpiece so that the dirt, rust or coating on the surface can be evaporated or peeled off instantly, and the attachment or surface coating on the surface of the cleaning object can be effectively removed at high speed to achieve a clean process. It is a new technology based on the interaction effect of laser and substance. Unlike the traditional mechanical cleaning method, chemical cleaning method and ultrasonic cleaning method (wet cleaning process), it does not need to use any organic solvent that destroys the ozone layer, no pollution, No noise, no harm to the human body and the environment, is a "green" cleaning technology.

As far as the mechanism of laser cleaning is concerned, laser cleaning uses a cleaning substrate (also called a matrix) and surface attachments (dirt) to have a very different absorption coefficient for a certain wavelength of laser energy. Most of the laser energy radiated to the surface is absorbed by the surface attachments, causing it to be heated or vaporized or evaporated, or instantaneously expanded, and driven by the steam flow formed on the surface, detaching from the surface of the object for cleaning purposes.

It is specifically used for tire mold cleaning. The mold absorbs laser light of a specific wavelength. The energy is extremely small and will not cause damage. The dirt on the surface of the mold (sulfide, an inorganic oxide, silicone oil, carbon black, etc.) absorbs a lot of energy and is instantly expanded. Vaporization and evaporation, take away from the mold surface, so as to achieve the cleaning effect.

The main methods of laser cleaning are:

1) Laser dry cleaning method. That is, using pulsed laser direct radiation decontamination;

2) Laser + liquid film method. That is, first deposit a liquid film on the surface of the substrate, and then use laser radiation to decontaminate;

3) Laser + inert gas method, that is, at the same time of laser radiation, sweep the surface of the substrate with inert gas. When the dirt is peeled from the surface, it will be blown away by the gas immediately to avoid the surface from being contaminated and oxidized again;

4) After using the laser to loosen the dirt, clean it with a non-corrosive chemical method.

At present, the first three methods are commonly used, and the fourth method is only found in the cleaning of stone cultural relics.

The advantages of laser cleaning are: high efficiency, speed, low cost, small thermal and mechanical load on the mold, will not damage the workpiece being cleaned; waste can be recycled, no environmental pollution; safe and reliable, does not damage the health of the operator; Can remove all kinds of dirt with different thickness and different composition; the cleaning process is easy to realize automatic control, remote cleaning and so on.

Disadvantages of laser cleaning: high equipment investment, high maintenance, and use requirements, technology monopolized by foreign countries, subject to technical services, and parts supply.

(2) Dry ice cleaning technology

Dry ice cleaning technology began in the late 1980s and was first applied in the domestic industrial field in the United States. After more than 20 years of development, both in technology, equipment, and applications have been gradually improved and developed and has become a practical cleaning technology.

1) Brief introduction of dry ice cleaning technology

Dry ice cleaning technology is to make liquid CO2 into dry ice spherical particles of a certain size (2-14mm value diameter) through a dry ice preparation machine (granulator), using compressed air as a power source, and spray dry ice washing machine to compare dry ice spherical particles High-speed injection onto the surface of the object to be cleaned (the working principle is similar to the principle of the sandblasting process). The dry ice particles not only have a grinding and impact effect on the dirt surface, but more importantly, the low-temperature effect and sublimation effect of the dry ice particles make the dirt quickly Freeze and embrittlement, and then produce different cold shrinkage effects with the materials it contacts, thereby reducing the adhesion of dirt on the surface of the material, plus the grinding and impact of dry ice particles, the blowing, and shearing of compressed air, The dirt is stripped from the surface to be cleaned in a solid form, and the purpose of removing the dirt is achieved.

2) Dry ice cleaning method

The dry ice cleaning system consists of two parts: the first part is the dry ice granulation system, which functions to solidify the liquid CO2 into dry ice and make it into high-density, equal-size dry ice particles; the second part is the dry ice spray cleaning system, which uses air The compressed air supplied by the press or the factory itself sprays the high-density dry ice particles loaded into the jet cleaning machine with the compressed air through the spray gun to the surface of the workpiece to be cleaned.

The jet cleaning machine can be equipped with a variety of spray guns to clean a variety of dirt and various surfaces. The dry ice granulator and dry ice blasting machine can be assembled together for on-site use, or the dry ice can be pre-granulated, stored in a plastic sealed container, transported to the cleaning construction site, and loaded into the jet cleaning machine for cleaning construction. Generally, the pre-made dry ice particles stored in a sealed container can be kept for 7-10 days.

3) Technical characteristics and process parameters

Dry ice as the cleaning medium of this cleaning technology, its unique physical properties, and process technology determine the following technical characteristics of cleaning tire molds: the hot tire molds that have just been used can be cleaned directly on the vulcanizer without cooling and without removing the mold The cleaning task can be completed; online cleaning can be achieved without damaging the mold and leaving no residue; the small exhaust holes can be cleaned, which is impossible for other cleaning methods; it does not pollute the environment and is non-toxic and non-toxic to the operator Irritation; low labor intensity and short cleaning cycle.

Through current research and the renaissance trend of potato varieties that have been more or less forgotten, the industry is encouraged to test various new tubers. Each potato tuber has its own characteristics and is suitable for processing into different products. Potato Business Network interviewed Arnaud Jansse, an application engineer at Florigo (tna solution), and asked him which potato varieties are best for making potato chips. ——Ioana Oancea

Generally speaking, if it can bring benefits, potato chips producers have higher openness and acceptance of new varieties, such as higher yields and better quality. There are various types of varieties, some are more suitable for storage, some have higher dry matter content, and some types have low reducing sugar content, Jansse explained.

Large-scale snack manufacturers often have their own R & D plans, from raw materials (potatoes, vegetables) to final products and seasoning and packaging. Usually, the process of discovering new varieties begins with the manufacturer's research on new varieties and the growers who seek these new varieties, initially from small test fields. The next time, producers instruct their growers or suppliers to grow new varieties.

When potatoes are harvested, small batches of potatoes are tested in laboratories, pilot factories, or major factories. Jansse said that usually testing means "fried". Test criteria include color, yield based on dry matter content, oil absorption and appearance.

 A potato variety considered suitable for making potato chips must meet the following criteria:

• High dry matter content (21-25%)

• Low reducing sugar content (<0.3-3.5%)

• Low or no geranium content

• Round

• Smooth surface, shallow potholes

• Alluring colors, such as white, cream, yellow

• Not easily scratched

• Seasonal availability: early harvest period, or suitable for long-term storage

Of course, an important feature at present is that the tubers need to contain lower levels of reducing sugars and asparagine, which means that the possibility of acrylamide formation in potato chips is reduced, while also meeting the new requirements of the European Commission.

All in all, manufacturers are looking for the most suitable potato varieties at a reasonable cost, but in practical applications, the selection criteria may vary depending on the growth of certain potato varieties, that is, potato performance. Then, choose based on availability and buy the best potato type they can buy locally.

According to the application engineer of Florigo, the most common potato varieties in the field are Lady Rosetta, Lady Claire, Saturna, Hermes and Verdi.

Other potato types suitable for potato chips production include Agria, Lady Amarilla, Lady Britta, Lady Jo, Bintje, Premiere, Atlantic, Endeavour, Ranger Russet (USA) and Pink Lady (USA). In the United States, a special type of "Innate" is used to produce French fries. It is the first genetically modified potato variety approved in the United States and can produce less suspicious carcinogen acrylamide.

Heating and cooling are the necessary conditions for plastic extrusion molding to proceed smoothly. In order to make the plastic always extrude within the temperature range required by its processing technology, it is generally achieved by continuously adjusting the temperature of the material in the barrel of the plastic extruder by means of heating or cooling.

plastic-granulator-machine-6-1.jpg

Cylinder heating of the plastic extruder is to provide heat for the plasticization of the raw materials in the cylinder. Barrel cooling is to prevent the raw materials from generating excessive heat during extrusion and frictional plasticization to increase the temperature. The alternating use of heating and cooling keeps the heat of the barrel of the plastic extruder within the process temperature range required for the plasticization of the raw materials, ensuring the normal and continuous production of the plastic extruder. The heating method of the barrel: resistance heating, electric induction heating, heating medium heating. There are two cooling methods: water cooling and air cooling.

The heating method of Shuliy mechanical plastic extruder adopts a resistance heating method. The heater adopts a cast aluminum heater. The resistance wire is placed in a metal tube and filled with magnesium oxide and other insulating materials to make an electric heating rod, which is bent according to the desired shape. , And then cast into the aluminum alloy. It has small size, lightweight, easy assembly and disassembly, high heating temperature, long service life, and has the properties of moisture-proof, shock-proof, and explosion-proof.

However, Shuliy mechanical plastic extruders use air cooling, which mainly uses air cooling, that is, using an electric blower to blow the air to the part of the barrel that needs to be cooled, taking away the heat of the barrel and cooling the barrel. But the cooling rate is slow.

The plastic granulator includes two parts: machine head and a fixed mold.

1. The role of the machine head

The machine head is the main component for forming sodium extruded parts. It changes the molten plastic from the extruder from a spiral motion to linear motion, and it is further gradually evolved. And continuous profiles with similar shapes.

plastic-granulator-machine-6-1.jpg

2. Classification of the nose
(1) Classification of plastic parts by extrusion
Usually extruded plastic parts include pipes, rods, plates, sheets, nets, monofilaments, pellets, various profiles, blown films, wires, and cables, etc. The machine heads are called pipe heads and rods Nose.

(2) Classification by product export direction
It can be divided into straight head and horizontal head. The material flow direction in the former head is consistent with the axial direction of the extruder screw, such as a hard tube head: the latter material flow direction is at a certain angle to the axial direction of the extruder like the cable head. The role of stereotypes

Although the plastic parts extruded from the machine head have a predetermined shape, but because the temperature of the part is relatively high, it will be deformed due to its own weight, so it is necessary to use a sizing device to cool and shape the shape of the part. Obtain the correct size, geometry, and surface quality that meet the requirements. Usually cooling, pressurizing, or vacuuming is used to stabilize the plastic shape extruded from the die and finish it, so as to obtain a more accurate cross-sectional size and a brighter surface. Pieces.

What is dry ice cleaning?

Dry ice blasting, also known as cold spray, uses compressed air as the power and carrier, using dry ice particles as the accelerated particles, and sprays them onto the surface of the object to be cleaned by a special spray washing machine. Energy conversion such as melting and melting makes the dirt, oil stains and residual impurities on the surface of the object to be frozen quickly frozen, thereby condensing, embrittlement, peeling, and at the same time, it is removed with the airflow. It will not cause any damage to the surface of the object to be cleaned, especially the metal surface, nor will it affect the smoothness of the metal surface.

The specific blasting process includes low-temperature freezing stripping, purge stripping, impact stripping.

Low-temperature freeze peeling

When the dry ice particles of -78.5 ℃ act on the surface of the object to be cleaned, the embrittlement dirt is first frozen. The adsorption force on the surface decreases sharply, while the surface area increases and part of the dirt can be peeled off automatically.

Purge strip

Under the environment of compressed air as the power, it generates a shear force on the embrittled dirt, causing a mechanical fracture. Due to the large difference in low-temperature shrinkage between the dirt and the surface of the cleaned object, stress concentration occurs at the contact surface. Dirt is peeled off under the action of shear force.

Impact stripping

When the high-speed dry ice particles collide with the surface of the increased dirt, the above kinetic energy is transferred to the dirt, overcoming the reduced adhesion, and the resulting shear force causes the dirt to roll away with the airflow. The purpose of removing dirt.

Dry ice cleaning technology is a relatively new process that removes stubborn dirt residues in a particularly gentle and environmentally friendly manner. So how does it stand out from other cleaning methods? The following low-temperature dry ice cleaning machine manufacturers will tell you its advantages.

1. Cost-saving Because carbon dioxide is a component of the atmosphere, it is very convenient to use and cheap, and the power-consuming equipment only has an air compressor. Dry ice evaporates directly during the cleaning process, and there is no cost for cleaning the cleaning medium.

2. The dry cleaning process is different from steam and high-pressure water cleaning. Dry ice cleaning has no damage to wires, control elements, and switches. After cleaning, the possibility of equipment rusting is greatly reduced compared with water cleaning. In the food industry, dry ice cleaning greatly reduces the possibility of bacterial growth compared to water cleaning.

3. Environmental safety CO2 is a non-toxic substance that meets the safety requirements of the US Department of Agriculture (USDA), Food and Drug Administration (FDA), and Environmental Protection Agency (EPA). With dry ice cleaning instead of toxic chemical substances cleaning, employees can fundamentally avoid the infringement of chemical substances. Because CO2 is heavier than air, ventilation must be ensured when operating dry ice cleaning in enclosed spaces or sinking places, and pay attention to safety.

4. Extend the service life of the equipment Unlike sand particles, walnut shells, plastic particles, and other abrasive media, dry ice particles are not abrasive. It avoids the corrosion and harm of the mold by the chemical cleaning method, the mechanical damage, and scratches of the mold by the mechanical cleaning method does not damage the tolerance and does not damage the bearings and machinery. In addition, online cleaning avoids accidental damage during mold disassembly.

5. Efficient dry ice cleaning can be cleaned online, greatly reducing the parking time, without the need to lower the temperature to disassemble the mold, and repeated loading and unloading lead to defects such as reduced mold accuracy. It can eliminate the two time-consuming processes of disassembling the mold and waiting for the mold to cool down, which can reduce the strike time by about 80% -95%, so as to have efficient production efficiency and less time consumption.

6. Wide range of use For different cleaning conditions, as long as the different dry ice cleaning nozzles are replaced, the cleaning working distance is improved to meet different needs. The operation is a simple, safe, low cost, and the comprehensive benefit is considerable.

How to make dry ice

First let ’s get to know what dry ice is:

Dry ice is a common name for solid carbon dioxide CO2. It is a non-toxic and odorless white solid. Its shape is a powder, large and small particles, and various blocks. The temperature of dry ice is minus 78.5 degrees Celsius. At normal temperature and pressure, dry ice sublimates directly into carbon dioxide CO2 gas with an expansion rate of about 800 times.

So how is dry ice made and produced?

Dry ice is made by reducing the pressure of liquid carbon dioxide. Part of the liquid carbon dioxide evaporates and absorbs a lot of heat so that the other part of the carbon dioxide is cooled into a snow-like solid, which is dry ice. There are mainly the following methods:
 

1. At home to make dry ice, carbon dioxide fire extinguisher + cloth bag

Prepare a cloth bag, put it on the exit of the carbon dioxide fire extinguisher, and turn on the fire extinguisher switch. A small amount of white "snow" will form in the cloth bag near the spout. This is dry ice, but the amount is very small, and the actual significance is not great.


2. Manually make dry ice: carbon dioxide cylinder + small manual dry ice making machine Sida low-temperature KBS series

Buy liquid carbon dioxide at the gas operation station, you can get carbon dioxide cylinders, connect to the four-temperature low-temperature KBS-01, KBS-02 or KBS-04 small mini dry ice machine, open the valve, you can produce dry ice, low cost, simple operation, It is suitable for users of hotels, restaurants, bars, cloud effect, laboratory low-temperature test, mechanical cold assembly.


3. Fully automatic preparation of dry ice: carbon dioxide dewar or storage tank + automatic dry ice making machine Sida low-temperature KBM particle series or KBK block series

Purchase liquid carbon dioxide dewar or storage tank in the market, and purchase liquid carbon dioxide in the gas company. According to the dry ice shape and output requirements, choose KBM-80, KBM-150, KBM-200, KBM-300, KBM- 500, or choose KBK to block dry ice machine KBK-100A. The dry ice produced in this way has high density, good quality, and large output. It is widely used in the catering smoke effect, refrigerated transportation, cooling and preservation, and industrial dry ice cleaning. It is very suitable for users who sell industrial dry ice.

Each production process of the charcoal machine has a direct relationship with the charcoal production effect. The charcoal process requires four steps: crushing, rod making, drying and carbonization. Each step requires different equipment and technical requirements. In order to produce high-quality charcoal, every step must be skillfully operated. So what are the requirements of each step of the charcoal machine?

1. In the process of crushing raw materials, the size of the crushed large materials should be kept between 10mm, and do not exceed this particle size, so as to affect the operation;

2. During the rod making process, the density of the rod body should be reasonably controlled, and the density value to be maintained should be a 1: 1 ratio;

3. For drying materials, the humidity of the materials should be controlled at the optimal dryness. Generally, the controlled moisture content is 6% ~ 12%;

4. During the carbonization process, the temperature of the carbonization should be controlled to the optimal carbonization temperature range. The carbonization temperature is generally required to be between 550-600 degrees, which is the optimal carbonization temperature range value.

       Recently, a customer friend from Zhengzhou called us and said that he has a lot of fruit trees in his hometown. Every year, he cuts a lot of fruit branches and throws them away as garbage. It is a pity that messy throwing on the ground is also a hindrance, so I thought to Find a device that can be used.

        We also have a customer response to the situation he responded to. This situation is most suitable for charcoal. The raw materials can be said to be free, so the profit margin is greatly improved. If there are many small branches, we recommend making charcoal. The equipment required for carbon is a pulverizer, rod making machine, dryer, and carbonization furnace. If it is a large branch, it is recommended to use the original charcoal machine to directly carbonize, and the tree stem to directly carbonize the charcoal (fruit charcoal).

        At present, the price of fruit charcoal on the market is still very ideal. Making good quality charcoal, using fruitwood or hard mixed wood, the carbon produced will have a higher calorific value than rice husk char.

        The discarded branches can be solved by reasonable use, and the next problem comes again. Sometimes the charcoal produced cannot be sold in time and needs to be stored, but what should be paid attention to when storing? How to store it?

        The charcoal machine completes the production process of charcoal after the raw materials are processed through the four processes of crushing, drying, rod making, and carbonization to produce charcoal. For some users, the charcoal produced is not directly sold and needs to be packaged and stored, and the storage time cannot be guaranteed.

Some charcoal is damaged and corroded when it is used. It cannot be used normally. This makes users question whether the charcoal produced by the charcoal machine is not effective, or what causes it. In fact, the key point is that the charcoal produced by the charcoal machine needs to be preservative treated.

        The ingenious anti-corrosion treatment measures of the charcoal produced by the charcoal machine are natural drying. Natural air-drying requires that the finished charcoal machine is air-dried at the place where the test machine is used. This process is mainly aimed at the changes in the charcoal cell structure caused by changes in the external environment so that it can be fully fixed to the greatest extent during the gradual change process, thereby avoiding the finished charcoal machine in Changes occurred during storage.
