Now let’s know Fresh Storage, Cold Storage, Freezer Room and Blast Freezer products.
The storage temperature of the fresh storage is generally 0 ℃ ~ 5 ℃, which is mainly used for fresh-keeping. That is, to maintain the original quality and freshness of agricultural products to a maximum extent for a long time, the living body of agricultural products does not die as much as possible, the cells are dormant in the process of refrigeration, reducing the loss of nutrients and maintaining the fresh quality. This is generally applied to fruits and vegetables. The current fruit and vegetable industry is concentrated in cultivation. In the process of transportation and sale, it is inevitable to use cold storage to maintain the proper nutritional content of fruits and vegetables.
The temperature of the cold storage is generally -15 ℃ ~ -18 ℃. Generally, the food is put into the cold storage step by step from time to time. After a period of time, the temperature of the cold storage reaches -18 ℃, and the pickup is also irregular. There is no specific requirement for this "time", which is a typical cold storage. For example, meat and aquatic products have higher storage temperature requirements to keep internal products from deteriorating. In addition, during the sale process, it is also necessary to take out and store it from time to time. The cold storages have food processing, medicine and vaccine cold rooms. The size can be customized. We CBFI can provide the one-stop solution cases for you.
The storage temperature of the cryogenic storage is generally -22 ～ -25. It uses a variety of refrigeration equipment, that is, artificial refrigeration, to maintain a certain low temperature indoors.
The characteristics of the low-temperature storage are: put the food into the cold storage step by step from time to time. After a period of time, the storage temperature of the cold storage reaches -25 ℃. There is no special design process and technical requirements for the cold storage during this period of time. There are strict requirements, between -22 ℃ ~ -25 ℃, this is a typical low-temperature storage.
The storage temperature of the cryogenic storage is generally below -30 degrees. The speed warehouse can ensure that the items can be quickly cooled in the shortest time after being placed in the cold storage. Compared with the quick-freezing cold storage and the freezer, the most remarkable feature is that the cooling speed is quite fast, most of the quick-freezing cold storage The cooling rate is about ten to twenty times that of the ordinary freezer.
The refrigeration load of a quick-freezing cold storage is generally several times or even several tens of times that of a refrigerator of the same size, and the cost of its refrigeration equipment and insulation materials is naturally much higher than that of the cold storage. For example, the cost of an 80-cubic refrigerator is generally about 30,000 to 50,000, and the cost of a quick-freezing refrigerator of the same size is more than 100,000 or even higher.
