COLD ROOM

                          China cold room introduction The choice of cold storage or cold storage is good, and many friends are very uptight. Some confuse the air cooler with the air-cooled air-conditioning unit. Some do not know how to choose. What is the best choice for the cold-storage air-conditioning system?Generally speaking, we do recommend the use of air coolers for easy installation. If it is a large-scale cold room, when the exterior height of the cold storage is high, the internal machine adopts a row tube, so the installation is inconvenient and has a certain potential safety hazard. The chiller is easy to dismantle and is suitable for use in high temperature storage.Low-temperature cold storage or ultra-low temperature cold storage, refrigeration encyclopedia recommended to use the row of tubes, the market to do low-temperature cold storage, using a row of tubes out of many machines. Considering from a long-term perspective, the use of platoon pipes makes the cooling capacity in the cold storage even and saves energy and power, but it also has certain disadvantages. The price is relatively high, and it is inconvenient to install compared to chillers.It is perfectly possible to use a chiller at a low temperature of minus 18 degrees or minus 25 degrees, and there is no need to worry about the frosting problem. However, if it is a cryogenic cold storage, it is recommended to use a platoon pipe. Of course, this is closely related to the budget of the cold storage owners.Cold storage chooses cooling fan or row pipe from the following points of view1. From the cooling effect:The cooling effect of the pipe is slightly better than that of the cooling fan. The heat conduction of the pipe is faster than the cooling fan, especially the aluminum row, so the general high-temperature library can be used with a cooling fan. We recommend using the pipe for low temperature or ultra-low temperature storage. , And because the distribution of the pipe is relatively balanced, so the cooling capacity is relatively uniform, can achieve the effect of energy saving.2. From the scope of application:Because the row pipe is a pipe type evaporator, it can strongly lock in moisture. Because the air blower is a wind blower, it will evaporate water, making the product in the store dry and wither. Therefore, it is suitable for products with a lot of water, such as pipe line. Ice cream ice cream, fruits and vegetables, etc., and the chiller, then apply to dry goods, dried fresh, frozen meat, etc., so generally choose to install pipe or fan, mainly to see which match your product more.3. From the height of the library:If it is a large-scale cold storage, and the cold room library has a relatively high external height, it is recommended that the internal unit use a cooling fan. If the exhaust pipe is used, the installation is very inconvenient and there is a certain potential safety hazard. The chiller is more convenient to use in high warehouses because of disassembly and assembly.4. From the perspective of economic adjustment:In general, due to the cooling performance and production cost of the pipe, the price of the pipe is generally slightly higher than that of the cooling fan, especially the aluminum pipe. However, the long-term operation of the cooler bank consumes more power than the aluminum pipe storage. Whether it is a fan or a fan, it is still based on the budget.  

What is a blast freezer?Quick-freezing cold storage refers to a method of quickly freezing food through its maximum ice crystal generation area and quickly freezing when the average temperature reaches -18 ° C.The temperature of the freezer is generally -15 ° C to -35 ° C. Mainly used for low-temperature fast freezing of food, medicine, medicinal materials, chemical raw materials and other items. With fast cooling, good freshness and so on.The so-called rapid freezing refers to the method of quickly freezing food through its maximum ice crystal generation area and quickly freezing when the average temperature reaches -18 ° C.During the freezing process, various changes occur in food, such as physical changes (volume, thermal conductivity, specific heat, dry loss, etc.), chemical changes (protein denaturation, discoloration, etc.), changes in cell tissue, and biological and microbial Changes, etc.The characteristic of fast frozen food is that it maintains the original nutritional value and color and aroma of the food to the maximum extent.That is to say, during the freezing process, a quick guarantee must be kept to ensure that the above-mentioned various changes in food have reached the greatest reversibility.Large-scale quick-freezing warehouses are all part of cold storage, and are built with other storage areas (low-temperature storage, shady storage, etc.).If you want to build a small-scale quick-freezing warehouse, you can choose a combined cold storage, which is the assembly type said in the industry. Such an assembly cold storage saves costs, saves construction time, and has complete functions.

China blast freezer Container blast freezer can be assembled in the container, can be based on customer quick freezer demand, equipped with refrigeration equipment. and heat preservation body selection integrated planning, compact construction, high refrigeration efficiency. Freezer is usually controlled at -35 to -40 degrees, fast cooling speed and high efficiency. The cold storage container uses the standard IC type container, the basic construction scale is 6058mm*2438mm*2438mm, equipped with central main temperature zone, built-in shelf, the front part is the sub-temperature zone and storage area, the rear part is the generator cabin and the refrigeration unit. The key parts of Refrigeration Unit are selected by famous Brand in the World Products, unit running firmly, leading control, excellent function, simple installation, efficient saving electricity, low protection rate. The unit is divided into a single unit and a two-stage cryogenic unit, according to the size of the sensitive matching. According to some special occasions, can also be customized noise reducing chassis cover.In the main temperature area of the container cold storage, the large plate insulation structure is used, and the scale (L*W *H) is 3100mm*1920mm *1740mm. The inside of the container freezer is divided into two parts by the static pressure air plate, the upper part is the static air chamber, the lower part is the constant temperature region, the height is 270mm and 1740mm. In order to decrease the temperature difference in the constant temperature zone, the structure of the over static pressure chamber can produce stable and uniform layer flow wind, and the first place in the constant temperature area needs to be refrigerated. High temperature curing resin adhesive is used for the main temperature zone wall plate. The aluminum profile skeleton, rust proof aluminum plate, heat insulation bridge and rigid polyurethane foam are bonded and limited to form, the thickness is 10. 0mm. The top of the back wall is provided with an air vent and an external transpiration cabin. The transpiration system is installed in the transpiration tank, and the wall plate structure is the same as the main temperature zone, and the thickness is 80 mm.

Low temperature and humidity thawing device adopts unique efficient humidifier, guarantees the thawing process under different temperature environment humidity requirement, make different thaw frozen meat to achieve high quality, through the control program to realize automatic thawing process.Low temperature high humidity defrosting machine realized that the time of defrosting was shortened, the defrost was uniform, the temperature of the food center was small and the temperature of the surface temperature was small, the loss rate of the juice was low, so that the meat returned to fresh condition after thawing.The low temperature high humidity vacuum defrosting machine adopts full automatic control.Defrost time and temperature can be adjusted according to different frozen product requirements. After defrosting, it will automatically be refrigerated to keep fresh, and fresh food can be taken out of the refrigerated state at any time.The advantages of other thawing methods cannot be compared, and it is widely used in meat, aquatic products and other frozen foods.Frozen meat thawing line, frozen chicken leg defrosting machine features:1.
