Preservation storage is applied to preservation of meat and dairy, fresh eggs, fruits and vegetables etc, to make the food at a lower temperature, but the temperature is not lower than 0℃, so that it can keep the food as fresh as possible.

There are no specific requirements in the period of refrigerating food, and in addition, the temperature in the cold storage must maintain within the range of －15℃ to －18℃.

cold-chamber general temperature －22℃～－25℃

Mainly applied to food storage at －22℃ to－25℃. Under the above circumstances, the food doesn’t go bad. For example, when the temperature is higher than －25℃, the fragrance of ice cream disappears, so do seafood. With food put into the cold storage aperiodically step by step, after a while, the temperature reaches－25℃, during which period there are no special requirement, but after the temperature is constant, there are strict demands on temperature in the cold storage.

quick-frozen compartment temperature blow －30℃

Mainly applied to the freezing food such as quick-frozen dumpling, and quick-frozen vegetables which should be frozen rapidly in the fixed period.
