Quick freezing cold storage design ideas: 1. Know the purpose of the cold storage and go to the cold storage site to collect field parameters. The specific parameters of the cold storage site are very important. The actual size of the cold storage site and the surrounding environment all directly affect the cold storage equipment and the construction drawings of the cold storage. 2. Select the appropriate freezing temperature and freezing time according to the characteristics of the items to be stored in the cold storage. Different types of products have different temperature requirements. For example, the temperature requirements for quick-freezing stores such as tuna are different from those of fresh products.

How to distinguish between various cold storages: According to the different products that are placed, we generally divide the cold storages into the following types: 1. The storage temperature of the fresh storage is generally 0 ℃ ~ 5 ℃, which is mainly used for fresh storage That is, to maintain the original quality and freshness of agricultural products to a maximum extent for a long time, and the living body of agricultural products should not die as much as possible, and the cells are in a dormant state during the refrigeration process, reducing the loss of nutrition and maintaining the fresh quality. This is generally used in fruits and vegetables.

What is a freezer? Quick-freezing cold storage refers to a method of quickly freezing food through its maximum ice crystal generation area and quickly freezing when the average temperature reaches -18 ° C. The temperature of the freezer is generally -15 ° C to -35 ° C. Mainly used for low-temperature fast freezing of food, medicine, medicinal materials, chemical raw materials and other items. With fast cooling, good freshness and so on. The so-called rapid freezing refers to the method of quickly freezing food when it passes through its largest ice crystal generation area and when the average temperature reaches -18 ° C.

Calculation of effective storage volume in cold storage 1. Calculation of tonnage in cold storage: 1. Assembled light steel structure cold storage: Tonnage of assembled light steel structure cold storage = content of refrigerated room × volume utilization factor × unit weight of food Internal volume of cold storage room of prefabricated light-steel structure cold storage = (inside the storehouse) length × width × height (cubic): volume utilization factor (stacking) of prefabricated light-steel structure cold storage: 500 ～ 1000 cubic meters = 0.40; Cubic = 0.50; 2001 ～ 10000 cubic meters = 0.55; 10001 ～ 15000 cubic meters = 0.60: Volume utilization factor (shelf) of fabricated light steel structure cold storage: 4-6 layers of shelves, effective volume * 0.5; 6-8 layers of shelves, effective Volume * 0.6; 8-10 layers of shelves, effective volume * 0.8; shelves of more than 10 layers; effective volume * 1.0-1.42, civil structure cold storage cold storage civil structure cold storage tonnage = inside the cold storage room
