Construction of general cold storage

The common cold storage generally refers to all cold stores except the controlled atmosphere storage. In general, the prefabricated cold storage is mainly composed of steel structure framework, supplemented by heat insulation wall, top cover and underframe, so as to meet the performance requirements of heat insulation, moisture resistance and temperature reduction. The thermal insulation of prefabricated cold storage is mainly composed of heat insulation wall plate (wall), top plate (patio plate), bottom plate, door, support plate and base. They are assembled and fixed by special structure of child and mother hook Ensure good heat insulation and air tightness of cold storage.

 General cold storage
The cold storage door can not only be opened flexibly, but also be closed tightly and used reliably. In addition, the wooden parts in the cold storage door should be dried and antiseptic; the cold storage door should be equipped with lock and handle, and the safety unlocking device should be installed; the low-temperature cold storage door frame should be installed with electric heater with voltage below 24 V to prevent condensation water and condensation. Moisture proof lamp is installed in the warehouse, the temperature measuring element is placed in the uniform place in the warehouse, and the temperature indicator is installed in the position easy to observe on the exterior wall of the warehouse. All chromium or zinc coating shall be uniform, and welding parts and connecting parts must be firm and moisture-proof. In addition to the sufficient bearing capacity of the bottom plate of the cold storage, the loading and unloading operation of the transport equipment should also be considered for the large-scale prefabricated cold storage.

The three most common refrigerators are:

1. Fresh storage

The fresh-keeping storehouse is a cold storage for the purpose of keeping fresh. The fresh-keeping storehouse can keep the freshness of agricultural products to the maximum extent, and still keep the freshness and quality of fresh picked or close to steel picking after a period of storage.

2. Meat cold storage

Meat cold storage is used for meat storage, meat cold storage is suitable for meat, aquatic products, poultry, frozen meat processing, retail and wholesale industries. The types of frozen meat food in meat cold storage include livestock meat, poultry meat, beef, mutton, pork, dog meat, chicken, duck, goose, fish, seafood and other meat products.

3. Low temperature storage

Ice cream and seafood need to be stored at - 25 ℃ to avoid deterioration. For example, when ice cream is not stored at - 25 ℃, its flavor will be lost; the taste and taste of seafood will be much worse;
