The processing method of preserving fruits by low temperature quick freezing. After the fruit is frozen, the internal biochemical process stops. Since most of the water content has been frozen into ice, the microorganisms have no water necessary for life, and the low temperature also hinders the activity and reproduction of the microorganisms, so the fruit can be preserved for a long time.

The function of the logistics cold storage is transformed from the "low temperature storage" type of the traditional cold storage to the "circulation type" and "cold chain logistics distribution" type, and its facilities are constructed in accordance with the requirements of the low temperature distribution center.
