If you want to build a cold storage, but you don't know what type to build, you need to know what types of cold storage there are!
The first type of fresh-keeping warehouse is generally 0-5, which is mainly used for preservation, maximizing the quality and freshness of agricultural products, and is generally used for the storage of food and drugs such as fruits and vegetables.
The second type of cold storage is generally in -15--18, mainly used for frozen meat, seafood, medicine and other materials, long-term frozen storage.
The third type of frozen low-temperature storage temperature is generally -22--25, with a variety of refrigeration equipment, so that the temperature in the warehouse continues to keep low, can store ice cream, seafood, etc.
The fourth type of controlled atmosphere storage, the controlled atmosphere storage on the basis of the fresh-keeping warehouse increases the adjustment of gas components, mainly used for the storage of fruits and vegetables, for off-season sales use, through the storage environment temperature, humidity, carbon dioxide, oxygen concentration and ethylene concentration adjustment control, so as to inhibit the respiration of fruits and vegetables, delay the process of metabolism, better maintain the freshness of fruits and vegetables, and extend the storage period and freshness of fruits and vegetables.
For friends who don't know much about cold storage, you can refer to the following types:
1.Constant temperature cold storage temperature range: 10 20 It is mainly used for constant temperature storage of medicines, food and other materials.
2.Fresh-keeping cold storage temperature range: 0 15 Mainly used for fruits, vegetables, medicines, food, bread, fish feed, dry goods and other materials, short-term fresh storage.
3.Freezer temperature range: -5 -18 Mainly used for frozen meat, seafood, medicine and other materials, long-term frozen storage.
4.The temperature range of quick-frozen cold storage: -30 -35, mainly used for quick-freezing of food, beverage raw materials, fruits and vegetables, etc.
5.Ultra-low temperature cold storage temperature range: -60 -80, mainly used for tuna, medicine and other low-temperature freezing.
6.Special types of cold storage include (modified atmosphere cold storage, industrial cold storage, explosion-proof cold storage, pharmaceutical cold storage, wet garbage room cold storage, etc.).
7.Controlled atmosphere cold storage temperature range: 0 15 is mainly used to store fruits and vegetables, and is used for off-season sales.
