Definition of cold room standard: Cold room is a storage building complex with artificial cooling and cooling function, including refrigeration machine room, power transformation and distribution room, etc.
Features of cold room
Cold room is part of the cold chain logistics, and its main purpose is the long-term storage and turnover of goods. For example, in the freezing processing and refrigeration of food, artificial refrigeration is used to maintain a suitable temperature and humidity environment in the warehouse.
The walls and floors of the cold room are made of thermal insulation materials with good thermal insulation properties, such as polyurethane, polystyrene foam (EPS), and extruded polystyrene foam (XPS). The main function is to reduce the loss of cooling and the transfer of heat outside the warehouse.
Examples of cold room application scenarios
1. Food storage and turnover
Dairy (milk), quick-frozen food (vermicelli, dumplings, steamed buns), honey and other fresh-keeping can be stored in cold room, which is widely used in the food industry, such as product processing and storage.
2. Preservation of medicinal products
Pharmaceutical products such as vaccines, plasma, etc. have strict requirements on storage temperature. The artificial refrigeration environment of the cold room can be set to an appropriate temperature and humidity environment according to the requirements of the product. List the storage requirements of common pharmaceutical products in cold room:
Vaccine library: 0℃~8℃, store vaccines and medicines.
Drug warehouse: 2 ℃ ~ 8 ℃, storage of drugs and biological products;
Blood bank: store blood, pharmaceutical and biological products at 5℃~1℃;
Low temperature insulation library: -20℃~-30℃ to store plasma, biological materials, vaccines, reagents;
Cryopreservation bank: -30℃~-80℃ to store placenta, semen, stem cells, plasma, bone marrow, biological samples.
3. Preservation of agricultural and sideline products
After harvesting, agricultural and sideline products can be kept fresh at room temperature for a short time and are easily perishable. Using cold room can solve the problem of difficulty in keeping fresh. The agricultural and sideline products that can be stored in the cold room are: eggs, fruits, vegetables, meat, seafood, aquatic products, etc.;
4. Storage of chemical products
Chemical products, such as sodium sulfide, are volatile, flammable, and explode when exposed to open flames. Therefore, the storage requirements must meet the requirements of "explosion-proof" and "safety". Explosion-proof cold room is a reliable storage method, which can realize the safety of production and storage of chemical products.
