Refrigerated quick-freezing storehouse is mainly classified as:

1、Preservation Storage: Storage temperature is generally 0℃～5℃.

Mainly used for fresh meat, dairy products, fresh eggs, fruits and vegetables. It keeps food at a lower temperature, which is usually no less than 0 C. In this environment, food can be kept as fresh as possible.

2、Refrigerator: Storage temperature is generally as follows－15℃～－18℃

Mainly used for food refrigeration. Some foods are put into the cold storage irregularly, while others are taken out of the cold storage irregularly. There is no specific requirement for the refrigeration time of the food, and the storage temperature is kept in the range of -15 ~18 ~C.

3、Low Temperature Storage: Storage Temperature is generally -22 ~25 C

It is mainly used for food storage at - 22 C to - 25 C. Only at this temperature can food not deteriorate. For example, when ice cream is stored at a temperature higher than - 25 C, its fragrance will disappear, and when seafood is stored at a temperature higher than this, its taste and taste will be much worse. The characteristics of low temperature storage are as follows: food is put into the cold storage step by step irregularly. After a period of time, there is no special requirement for the temperature of the cold storage. The temperature of the cold storage reaches - 25 C. When the temperature in the cold storage is constant, the requirement for the temperature of the cold storage is very strict.

4、Quick-frozen storage: Storage temperature is generally below - 30 C.

At the same time, cryogenic and ultra-low temperature refrigeration can be designed according to the special requirements of users.

As the model of cold storage is not shaped, we can design the corresponding cold storage plan for you according to your needs!
