Notes on making charcoal with charcoal machine

Making charcoal with a charcoal machine is straightforward to mention. There also are many tips. it's difficult to form charcoal without mastering the techniques.

First of all, the primary process is pulverization. The pulverizer is the simplest. Put the materials into the pulverizer and crush them. It should be noted that when installing the shredder, the bottom must be hit and glued with screws, otherwise, the speed of the shredder motor is going to be in no time, and therefore the constant vibration of the shredder will affect production.

The second step is drying. many of us think that the sawdust or sawdust is extremely dry and doesn't get to be dried. In fact, the sawdust that ordinary people look very dry doesn't meet the wants for creating rods. albeit it's brown, grab it together with your hands, it feels crispy, and hold it hard. Spreading the sawdust will loosen naturally and can not make a stick, you'll make a stick. concentrate on the dimensions of the hearth during the drying process. If the hearth is just too strong, the sawdust within the pipe could also be burned. If the hearth is just too small, the drying effect might not be achieved. This experience must be accumulated slowly.

The third step is to form rods. The technology of creating rods is far harder. First of all, the temperature must be adjusted. Generally, the temperature should be adjusted to 280 to 300 degrees at the start. After the rods are out, normal production is started then lowered. Adjust the temperature to about 260 degrees. the rationale why the temperature must be raised is because at the start of production, when the fabric is fed into the hopper, the temperature will drop sharply by dozens of degrees, and therefore the lowered temperature is simply suitable for production. At this point, the front of the propeller must be manually pressed with a wooden stick. It is often returned to the fabric and may be produced naturally after normal production, without hands. The rod making machine features a wearing part, which is that the propeller. The front of the propeller is during a high-temperature and high-pressure position. Long-term feeding and forming will cause the front to wear. At this point, it's necessary to re-weld and grind it before production. The welding rod, the angle and therefore the thickness of the welding mill are all tricks. one among them is that a manufacturer like Shuliy charcoal machine sends technicians to show welding and grinding technology, and therefore the other is that the charcoal factory staff must work for an extended time and slowly explore the experience.

The last step is carbonization. Carbonization has several points. First, when the hearth is closed, the furnace door and therefore the near fire mouth must be completely closed, and no trace of air is often penetrated, otherwise, the char is going to be burned into ashes. The second is to show on the condenser at the acceptable time to purify the black smoke generated during the conversation and extract the natural resin from it. This also requires some experience.

No additives needed for creating charcoal


We all know that for creating charcoal, most of its raw materials are sawdust, tree branches, and other wood materials, and eventually through the method of crushing, drying, making sticks, and carbonizing, the wood raw materials become black charcoal. Many friends are interested in this process, especially when employing a stick making machine, watching the dry raw materials instantly become dense semi-finished salary sticks, brooding about whether certain additives are added thereto. So, can we need additives for the assembly of charcoal?

If we carefully watch the video of the charcoal machine production process recorded by our factory, we'll know that the entire process has not added any additives. the rationale why raw materials are often squeezed into salary sticks is because these raw materials have a standard feature, that is, they contain certain lignin, and this lignin will soften and liquefy when it reaches 200-300 degrees Celsius, as long as a particular pressure is applied it's closely adhered to cellulose and cemented with adjacent particles and maybe solidified after cooling. and therefore the rod-making machine equipment produced by our factory uses the characteristics of lignin to squeeze the raw materials containing lignin into semi-finished products that we'd like, then put them into a carbonization furnace for carbonization to supply finished charcoal.

However, some customers have seen or heard that some equipment must add additives during the molding process. What I would like to mention is that they use a toner molding machine rather than a rod making machine, and their raw materials and processes are different. The carbon powder molding machine is to feature crushed carbon and other additives to extrusion molding to understand the recycling of crushed carbon.

In summary, whether or not additives are needed to form charcoal depends on what equipment is invested and what raw materials are used. However, generally, most of the purchasers who produce charcoal invest in charcoal machine equipment. the assembly process doesn't require additives. If customers don't understand, they will visit our factory and explain intimately.

Processing process of goat milk assembly line

Goat milk assembly line is employed to process goat milk assembly line. The goat milk contains rich nutrients. The molecules of goat milk are smaller than milk and straightforward for physical body to soak up. Some people ca n’t absorb the milk, so it are often absorbed by the goat milk. it's recognized that milk on the brink of breast milk has high nutritional value. Drinking goat milk is extremely good for your health. it's suitable for all types of individuals, whether it's the elderly, children, or children.

For goat milk assembly line, goat milk has an equivalent great smell as mutton. Some people cannot accept this smell and can't drink goat milk. we've designed degassing tanks for this example. After the goat milk is degassed, The taste is extremely small, and it's acceptable for many people. After milk is squeezed out from the pasture, it's then sterilized. After sterilization, it are often drunk directly. Nothing is added. it's nutritious and healthy. More and more, the marketplace for pasteurized goat milk remains excellent.

Processing process of goat milk production line: feeding milk → milk storage → pre-heating → homogenization → sterilization → degassing → cooling → finished milk storage → filling → capping → coding, filling bottles, cups, bags for supply Select, make yogurt with yogurt fermentation tank, consistent with the precise requirements of consumers to supply a customized solution, you'll map on-site customized solutions.

There are two sorts of goat milk production line: tank type and plate type. The tank type are often selected for processing one or two plenty of milk. The processing workshop are often quite 100 square meters. The operation of the entire set of kit is straightforward and only 2-3 people can.

For faulty milk assembly line equipment, it's not an emergency, you ought to first ask about the before and after process and therefore the phenomenon of the failure. For unfamiliar equipment, you ought to even be conversant in the circuit principle and structural characteristics, and follow the corresponding rules. Before disassembly, you want to be fully conversant in the functions, locations, connection methods, and relationships with other surrounding components of every milk assembly line . within the absence of assembly drawings, you ought to disassemble, draw sketches, and mark them.

Ten Principles of kit Maintenance for Pasteur Milk assembly line

1 Move your mouth first

For faulty milk assembly line equipment, don't answer the emergency, you ought to first ask about the before and after the failure and therefore the phenomenon of the failure. For unfamiliar equipment, you ought to even be conversant in the circuit principle and structural characteristics, and follow the corresponding rules. Before disassembly, you want to be fully conversant in the functions, locations, connection methods, and relationships with other surrounding components of every milk assembly line . within the absence of assembly drawings, you ought to disassemble, draw sketches, and mark them.

2 External first then internal

(1) Check the milk assembly line for obvious cracks and defects, understand its maintenance history, service life, etc., then check the within of the machine. Before dismantling, you ought to line up the encompassing failure factors, and you'll only dismantle after determining that it's an indoor failure. Otherwise, blindly dismantling, the equipment could also be repaired and worsened.

3 Machine first, electrical first

Only after confirming that the mechanical parts aren't faulty, the inspection of the milk assembly line is performed. When checking circuit faults, you ought to use testing equipment to seek out the faulty part, confirm that there are not any bad contact faults, then check the operating relationship between the road and therefore the machine to avoid misjudgment.

4 Static first, then dynamic

When the equipment isn't powered on, judge the standard of the buttons, contactors, thermal relays and fuses of the milk assembly line to work out the fault. Power on test, hear its sound, measure parameters, judge failure, and eventually perform maintenance. for instance, within the absence of phase of the motor, if the three-phase voltage value can't be distinguished, you ought to hear it and measure each phase voltage separately to work out which phase is flawed.

5 Clean first then repair

Clean the buttons, wiring points, and get in touch with points of the heavily polluted milk assembly line equipment and check whether the external control keys have failed. Many faults are caused by dirt and conductive dust blocks, and faults are often eliminated once cleaned.

6 Power first, then equipment

The failure rate of the facility supply part accounts for a high proportion of the whole faulty equipment, so it's often more efficient to repair the facility supply first.

7 Universal before special

Faults caused by the standard of assembly parts or other equipment failures generally account for about 50% of common failures. Most of the special faults of milk assembly line equipment are soft faults, which are measured and repaired by experience and instruments.

8 External first then internal

Don't rush to exchange damaged parts of the milk assembly line before you think about replacing the damaged parts of the milk assembly line when confirming that the peripheral circuit is normal.

9 DC first, then AC

During maintenance, the static operating point of the DC circuit must be checked before the dynamic operating point of the AC circuit.

10 Debug after failure

For the equipment of the milk assembly line that coexists with debugging and faults, the fault should be eliminated before debugging, and therefore the debugging must be performed under the premise of line speed of the milk assembly line.

  The charcoal machine is the main production equipment of charcoal production enterprises. In the daily production process, there are often small safety hazards that do not cause the operator's attention, resulting in serious production accidents or economic losses. Then the safety of charcoal machines in production is prone to occur. What are the hidden dangers, and how can we prevent these hidden dangers?

    The biggest safety hazard in the production process of the charcoal machine is electricity. The rod forming equipment of the charcoal machine uses an electric motor and uses 380V electricity. The body is made of steel material with good heat dissipation performance, but it is also conductive. Many operators did not notice this at the time of failure and accidentally touched the electric shock.

The solution to this hidden danger is to install a leakage point protection device at the power supply or an air protection switch at the bus to avoid accidental electric shock. Secondly, a grounding device must be installed on the body of the motor to avoid leakage.

    The second major safety hazard that is easy to occur in the production of charcoal machines is fire. The charring furnace is formed by carbonizing the formed charcoal rods after high-temperature combustion. Generally, the center hole part will carry Mars when it comes out. Mars needs to be poured out and fully cooled Do not stack them afterward, and do not stack them indoors, it is easy to cause a fire.

 There are other common safety hazards in the charcoal machine in the production process. Operators need to operate it carefully and carefully. It must not be careless. Safety production is more important than Taishan. The good operating habits of the charcoal machine are to ensure safety. Prerequisites for production.

When processing charcoal, the first problem is environmental protection. How to solve the problem of smoke emission in charcoal production?

The first is to completely solve the smoke exhaust problem of the charcoal kiln. This method is very thorough and does not have any flue gas exhaust. The disadvantage is that the investment is large and the supporting equipment needs to be installed when the factory is built. The smoke is recovered, and the smell of burning wood is still there. Basically, it can be smelled about 20 meters from the charcoal kiln, but the smoke is no longer visible. Therefore, it is most effective to have independent courtyards far from residential areas. And currently, the Environmental Protection Agency also recognizes this smoke recovery method, which can be described as once and for all.

The second method is to use biomass pyrolysis technology to produce charcoal. The flue gas produced by this method is more than 50% lower than that of the traditional charcoal kiln. It is suitable for use in charcoal plants with independent yards far from residential areas because Only a small amount of smoke is generated when the charcoal production equipment is ignited after basically 2 hours, so this method can also effectively solve the current smoke problem in charcoal production.

The third method is how to solve the problem of flue gas emissions during the production of charcoal. The solid wood charcoal has a certain difference from traditional raw charcoal because of its raw materials and production process, so we can optimize the process and carbonize according to the characteristics of charcoal production and the characteristics of raw materials. The reorganization of the project effectively solves the fume emission of charcoal during the rod making and firing process. At present, all charcoal production has undergone process reorganization and process optimization. The fume generated during the charcoal production process is lower than that of traditional charcoal production. More than 40% and the production cycle of charcoal is shortened, and the yield and quality of charcoal are also significantly improved.

There are two methods for cleaning and drying waste plastics: mechanical cleaning and manual cleaning. Some plastic products can only be cleaned manually after recycling, and a few plastic products are often mechanically cleaned and dried.

The following are the precise operations of mechanical cleaning and drying. Toyota Machinery reminds you that mechanical cleaning and drying are divided into intermittent and continuous.

Intermittent cleaning

First, wash waste plastic into a cistern , and use a plastic mixing machine to get rid of loose dirt, like sand and dirt, adhering to the surface of the plastic, and sink it to rock bottom of the tank. A special pump is employed to further purify the sedimentation tank; for dirt that's firmly attached, like printing inks and adhesive-coated paper labels, you'll manually detect the larger piece and put it in hot alkali after crushing by a plastic pulverizer Soak within the solution tank for a period of your time then rub and rub one another with mechanical stirring to get rid of dirt. Finally, the washed and crushed waste plastic is shipped to a centrifuge to be dried, and dried in two steps of hot air to a residual moisture of ≤0.5%.

2. Continuous cleaning

The waste plastic is shipped to a plastic crusher by a conveyer belt for coarse crushing, then sent to an outsized separation section, where sand and gravel are sunk into the water bottom and sent away regularly. The floating material enters the wet mill through the conveying roller, then enters the sedimentation tank. Everything heavier than water is separated, even the littlest particles are not any exception, achieving the simplest cleaning effect.

Many vaccines biological products must be stored between 2-8 degrees Celsius, which can only be done by dry ice, so the hospital has always used solid carbon dioxide dry ice to store and transport biological drugs such as vaccines. The refrigeration temperature of the existing ice packs cannot meet the requirements of frozen (-18 ° C) low-temperature ice packs, and is affected by the phase transition temperature of the refrigerant and the limitation of the duration of the refrigerant. Therefore, there is nothing more than storing vaccines with dry ice. Good solution to the problem of cryopreservation of vaccines.

Dry ice machine website:https://www.dry-ice-machine.com/dry-ice-granular-machine/

Low-temperature preservation method of radon vaccine

The vaccine is produced at low temperature from production, circulation and use. The low-temperature distribution refrigeration method generally uses cold storage materials (ice packs or dry ice) for refrigeration. During the distribution, the phase change of the cold storage materials is used to release the cold to maintain the low temperature of the refrigerator, thereby ensuring the safety of low-temperature goods. Dry ice is widely used in the distribution and storage of biological products, food, and aquatic products with a storage temperature below 0 degrees.

Can I bring a vaccine on the plane?

Basically it ’s very difficult. Things like 2-8 degrees can't pass security inspections, but it seems like you can bring some medicines such as diabetic insulin with you on the plane. You can try to apply for the transportation of dangerous goods to airlines, but not all airlines can handle the transportation of dangerous goods. It depends on the origin of your flight. See if there are airlines that can handle the transportation of dangerous goods. You can put some dry ice next to the vaccine, then put it in a small foam box and bring it back by luggage. This method is used when domestic vaccines are transported on a large scale or on a small scale. Because dry ice is carbon dioxide, you are not allowed to take it on board when it exceeds 2 kg. In this case, however, the price of dangerous goods transportation is quite expensive, and all are in the cargo hold.

Precautions for transporting vaccines in dry ice

Dry ice will generate 800 times its own volume of carbon dioxide gas during use, and there is a hidden danger of explosion. Therefore, when packaging dry ice, it must be treated with a foam insulation box. Therefore, major airlines have banned the use of dry ice as a refrigerant. However, because there is no suitable substitute to ensure the low temperature during the low-temperature distribution of a small amount of cargo, dry ice is still actually used in air transportation, but it cannot be carried on the plane casually, but it can go through the cargo passage and salute together In aviation, as long as the dry ice is packed in a foam insulation box in strict accordance with the requirements during transportation, it will not bring hidden dangers to aviation safety.

Benefits of dry ice preservation vaccine

Dry ice cryopreservation is the main way to distribute small quantities and small amounts of low-temperature goods. Limitations on the quality of other cold storage agents and the thermal insulation properties of the cabinet. After more than 24 hours, the time to maintain low temperature is generally not as long as dry ice, which is difficult to meet the requirements for long-term safe distribution of vaccines. The cost of using dry ice is low, no additional energy is needed, it is easy to use, and it is economical and environmentally friendly.

Dry ice is the recycling of carbon dioxide gas, so it will not aggravate the environment. As the freight refrigerant is the darling of logistics distribution, it is widely and widely used. The first vaccine dry ice must be stored and used with care. The dry ice you buy must be used immediately, or it will evaporate quickly.

How effective are the specimens stored on dry ice?

The use of dry ice for transporting specimens for preservation is excellent, because specimens generally need to be stored at low temperature, and the temperature of dry ice can just meet the requirements of specimens for storage temperature. When transporting specimens, you only need to place an appropriate amount of dry ice and place it next to the specimens to achieve a good cooling effect. The amount of dry ice used in the specimens should be appropriately increased or decreased according to the duration of the transport.

All aspects of specimen collection, transportation and preservation are critical

Carbon dioxide dry ice provides ultra-low temperature when transporting specimens, but the safety management of medical laboratories and the safety of specimen collection, transportation, testing, and processing are very important links. Clinical test specimens include body fluids, blood, secretions, excreta, and tissues. Whether an unknown pathogen can be found depends to a large extent on whether the specimens can be collected correctly and in a timely manner, which greatly affects the accuracy and validity of the test results. After the specimen is collected, it is generally required to be stored immediately under freezing conditions, and how to transport dry ice. This is how to use it, such as -80 degrees ultra-low temperature refrigerator, or -78 degrees dry ice can be used. These samples may generate virus particle aerosols during routine testing to cause cross-infection, in order to prevent cross-infection by inspectors.

Dry ice machine website:https://www.dry-ice-machine.com/dry-ice-granular-machine/

Container for transporting specimens

The collection is required during transportation. The transportation container, sterilized specimen container, transportation media, special test collection, and transportation tools must be strictly required. Prevent leakage caused by vibration, temperature, humidity, and pressure changes during transportation. How to transport the specimens with dry ice. During transportation, the specimens and dry ice should be stored together in a storage box with a good thermal insulation effect. Solid dry ice can provide a low temperature of -78 degrees, which provides a suitable temperature for specimen storage. Select a container that can be stored at a low temperature. Only specimens collected and transported with suitable containers can be used for testing. Specimen containers must be carefully reinforced to prevent leakage. Containers that have exceeded the shelf life cannot be used for collection and transportation.

Transportation packaging of specimens

When storing and transporting the specimens, it is important to pack them. It is necessary to seal the incubator to have a good thermal insulation effect. Generally, a thickened incubator for medical use is used to store dry ice specimens. The amount of specimen is sufficient to maintain the low temperature for a long time on the road, and it is less, and the dry ice volatilization is lost during the road, then your specimen will not have the conditions of low-temperature preservation, and the consequences can be imagined.

Culture medium for transportation

Must be cultivated in a clean environment. Place on appropriately tilted agar or transport media. Tighten the test tube and do not turn it sideways. Do not use agar medium and mixed culture. Place the tilted tube or virus in a sealable plastic bag. Place and transport the above items as required. Select the infectious specimen transport container according to the size of the original container. Carefully place the test tube in the middle of dry ice to ensure that the dry ice can provide the sample with sufficient low temperature during transportation. For specific methods of using dry ice to store and transport the sample, you can call the dry ice factory for consultation.

Labels should be tightly attached to prevent loss during transportation

There are a lot of things to pay attention to the transportation of specimens. Here is a special mention. Infectious disease specimens that are not properly labeled cannot be used for testing. The specimen must be written with the patient's name and a unique identification number. If a separate classification label is used, the label should be held tight to prevent loss during transport. The staining of specimens must not be affected during the labeling process. Each section must be labeled (it is not possible to label only the container in which the section is placed) and must be on the same side of the section where the specimen was inoculated.

You can also find cold chain logistics companies specializing in the transportation of temperature-sensitive items, and provide cold chain transportation services for customers in the fields of biopharmaceuticals, life sciences, new drug development, (professional contract research organizations) CRO, clinical medical center laboratories Companies, but also buy dry ice from the dry ice factory and sell it to you, so the price is high, it is better to buy dry ice back from the dry ice company yourself, and generally the company that sells dry ice provides medical dry ice storage boxes and specimens to store together It is very convenient. Some companies also handle specimen transportation for you. You can find a high point of trust to help you with the operation.

Scrap steel pipe processing equipment

Scrap crusher is a kind of crushing machine used to produce scrap steel crushing materials, mainly used for scrapping cars, scrapping household appliances and light and thin scrap steel. The main body casing is made of extra-thick steel plate, and the inner lining is made of high-manganese cast steel, which can be replaced. The following introduces the processing of scrap steel tubes and pipes.

Scrap steel pipe and iron sheet is our common waste metal steel in the scrap metal recycling enterprise and waste recycling station. Their steel composition is high, accompanied by certain rust and oxidation rust, and there are certain non-metal materials in the middle. Miscellaneous, these need to be solved, and the density of their metal and steel is very unstable because it is doped with a lot of scrap steel with too small gaps and low-density scrap steel profiles, pipes, iron sheets, skins, barrels, etc., resulting in high density And the weight is very low, which increases the transportation cost and storage is very inconvenient.

At this time, multiple factors need to be taken into account. Our preferred treatment method is crushing. First, the scrap steel pipe and iron sheet skin tube are unified and concentrated. The scrap steel pipe and iron sheet skin tube after the crushing by the scrap crusher are small in size. The shape is convenient for transportation and stacking. The scrap steel pipe and iron sheet skin tube after low-speed pre-crushing and high-speed hammer plate crushing of the scrap steel crusher are scrap steel crushed materials that have been crushed, decontaminated, and encrypted. Scrap iron and steel are neat in shape, complete in phase, uniform in size, high in density, high in purity and high in selling price. It is the preferred processing equipment for major waste recycling companies, iron and steel enterprises, smelters, foundries, scrap metal recycling stations, and metal recycling resource companies. .

How plastic pellet machines rejuvenate

Plastic products provide a lot of convenience for our production and life. This is a good side. On the other hand, it causes one of the larger sources of pollution in our lives. It will not be naturally degraded, and the appearance of plastic pellet machines is very good. This pollution is solved, and the recycling and reuse of waste plastics are realized.

How does the waste plastic in the plastic pellet machine rejuvenate? Let's take a closer look at it:

After the plastic is added to the hopper, the hopper smoothly falls on the screw and is bitten by the screw thread. As the screw rotates, the screw is forced to advance in the direction of the machine head, forming a mechanical conveying process. When the plastic is running from the feeding port to the machine head, the screw depth of the screw gradually decreases, and due to the resistance of the screen, the manifold and the machine head, a high pressure is formed during the plasticization process, which presses the material very much. Dense improves its thermal conductivity and helps the plastic melt quickly. At the same time, the gradually increasing pressure causes the gas originally existing between the granules to be discharged from the exhaust hole.

How to properly maintain plastic pellet machines

1. During the daily use of the plastic pellet machine, check the rotation of the disc from time to time. According to the specific provisions of the plastic pellet mill, the speed of the disc should be controlled within a reasonable range, so as not to cause the disc speed to be too fast. It affects the granularity of the product.

2. As the plastic granulator is a wet granulation model, the upper part of the disc is usually equipped with a spray device to wet the material and increase the viscosity of the material. Therefore, to ensure that the material has good adhesion, the spray should be checked frequently. Device to ensure that the water path in the spray device is unobstructed.

3. In the process of using the plastic pellet machine, it is particularly necessary to pay attention to the transmission parts of the plastic pellet machine, that is, the transmission gear. The rotation of the transmission gear is completed with the assistance of the lubricant, so it runs on the gear. In the process, regularly check its lubrication, and properly add lubricating oil and grease to the gears to ensure the good lubrication of the gears, so that the operation of the plastic pellet machine is more stable and reliable. plastic pellet machine

4. The overall structure of the plastic pellet machine is supported by a frame. When the machine is running, pay attention to check whether the anchor bolts connecting the frame to the ground are securely loosened. If the bolts are found loose, they must be timely Otherwise, the plastic pellet machine will generate strong vibration and noise during operation, and even cause accidents.

Dry ice refrigerator keeps good freshness

There are four major advantages of using dry ice for cold storage: easy to use, safe and efficient, sufficient cold storage capacity, and high-cost performance.

Dry ice produces a freezing effect, is easy to use in cold storage, and is ideal for cooling. In addition to greatly reducing the speed of food spoilage and chemical reactions, dry ice causes the water in food to form ice, which also seriously hinders the growth of microorganisms, which can greatly extend the optimal date of food.

       The use of dry ice for refrigerated foods can greatly extend the storage time of food. The refrigerated foods have a short shelf life. If they can be frozen, they can be stored for several months. Dry ice can reach a low temperature of -78 degrees, which is a temperature that cannot be achieved by some freezer cabinets. Therefore, the use of dry ice for the preservation and transportation of refrigerated food, meat, fish, vegetables, fruits, and eggs can greatly extend the storage time.

       The phase change temperature (from solid to gas) of dry ice is -78.5 ° C. The actual temperature in the incubator after adding dry ice is between -38 ° C and -55 ° C. Many medicines and foods need to be stored at -18 ° C freezing temperature. Therefore, dry ice is used for refrigerated storage.

        In fact, biopharmaceutical companies often use solid carbon dioxide refrigerated reagents to send to the field, and dry ice with carbon dioxide is easy to use. It will not turn into the water like water ice, and the temperature is low, and the cooling effect is ideal.


       Dry ice is widely used in refrigerated transportation. Therefore, dry ice has become a necessity for refrigerated transportation.

       Dry ice is easier to operate, safer and more convenient than refrigerated transport in liquid nitrogen tanks. It has been adopted by a considerable number of universities (mainly the College of Life Sciences) and research institutes in the world.

       Dry ice is used for cryogenic medical applications and low-temperature transportation of special drugs such as plasma and vaccines. Dry ice is used for the preservation and transportation of living cells and biological agents such as cell lines and genetic reagents. Biological laboratory living cell specimens are refrigerated with solid carbon dioxide. Refrigerated transportation of specimen blood in air transport is also indispensable for cooling.

      Dry ice is used for frozen and refrigerated transportation and preservation of lobster, crab, shark fin, salmon and other seafood. Dry ice also transports long- and short-distance transportation of electronic low-temperature materials and precision components.

Dry ice is used for the preservation of high-grade foods such as high-grade beef and mutton. In order to ensure that the moon cake ice cream always maintains excellent taste after being picked up and transported, Haagen-Dazs has always used dry ice to keep cold, and in recent years, special dry ice boxes have been made to keep the delicious flavors unchanged.

       The existing cold chain express and low-temperature distribution generally adopts the refrigeration mode of the refrigerated truck compressor refrigeration unit, which has large energy consumption. It is neither economical nor environmentally friendly for the current large number of low-temperature distribution. There is also some fresh cold chains expresses that use ice plates and other cold storage materials. Although it can be recovered, the cost is high, the secondary cold storage time is long, the turnover cycle is long, and the cold storage capacity is insufficient. There is a clear trend.

       In the past two years, a kind of rechargeable electric vehicle refrigerator has also occupied the fresh city distribution market, such as the fresh front refrigerated truck, which claims to perfectly solve the last mile of fresh food delivery. It does have advantages, but it also has a large investment, and the battery pack and frame have limited life cycles.

      Nowadays, cold chain logistics and intra-city distribution are increasingly using dry ice as a cold source and low-temperature distribution model. Dry ice is widely used in the distribution and storage of biological products, food, and aquatic products with a storage temperature below 0 degrees. Its excellent cooling effect makes dry ice the darling of cold chain distribution.

        The low-temperature distribution model that uses dry ice as a cold source is to use dry ice to release the cold capacity during transportation to maintain the low temperature of the cargo. This mode is very suitable for low-temperature and small-quantity delivery of goods. As a new low-temperature logistics distribution refrigeration method, the low-temperature distribution mode using dry ice has a lower cost, does not require additional energy, and is very convenient to use.

       Fresh foods have a short refrigerated storage period. If they can be frozen, they can be stored for several months. Long-term freezing must be kept at a low temperature of below -18 ° C. Dry ice can reach a low temperature of -78 ° C, which is impossible for most freezers. Achieved a low temperature. Therefore, the use of dry ice in the storage and transportation of refrigerated fresh food, meat, seafood, vegetables, fruits, and eggs, and the storage and transportation of eggs can greatly extend the storage time.

How to save dry ice?

Dry ice is also called solid carbon dioxide, which is 78.5 degrees below zero. It can directly sublimate non-toxic and odorless carbon dioxide gas. At the same time, very low-temperature carbon dioxide gas encounters air at room temperature, and immediately forms a white dense mist, which is beautiful and moving.

"Dry ice" is a common name for solid carbon dioxide. It can obtain an ultra-low temperature of -78.9 ℃ (otherwise). Compared with ordinary ice cubes (0 ℃), it has the characteristics of smaller volume and better cooling effect. It does not produce any water. At the same time, "dry ice" has a bactericidal effect, which can effectively prevent the breeding of bacteria in food and maintain food freshness. At present, "dry ice" is widely used in the preservation, transportation, and storage of fresh food, aquatic products, and processed meat, as well as in the pharmaceutical industry and low-temperature processing of cold-inserted metals.

How to save dry ice?

Dry ice must be stored in a special freezer, so that dry ice can be stored for 5-10 days. After the storage period has expired, the dry ice begins to form ice masses and even vaporize, and the use effect will be significantly reduced. After each use, be sure to remove the remaining dry ice from the machine and put it in the freezer.

● Never take dry ice directly by hand. Dry ice is extremely cold. Direct contact with the human body for a long time may cause frostbite of human skin tissue.

● Do not store dry ice in tightly sealed, small containers. Dry ice is extremely volatile and generates a gas 1000 times larger than the solid area, which creates huge pressure on the sealed container.

● It is best to dispose of the dry ice directly to make it naturally volatilize, so as to avoid the danger of improper storage. If it must be stored, a more commonly used method is to store it in a dry vacuum flask. There is vacuum insulation between the thermos bottle bladder and the outer bottle wall. The gas generated by the volatilization of dry ice can be released from the gap between the stopper and the bottle wall. To reduce internal pressure. But scientific experiments show that using this method can only save one day and one night.
