A cold storage is a kind of refrigeration and environmental space, is a fuzzy, cold storage can be divided into different types, such as have the cold storage, three-dimensional automatic cold storage, ultra-low temperature cold storage, etc., for different types of cold storage, snow fox frozen detailed analysis for everyone.
In addition to the traditional cooling material cold storage, frozen cold storage, various provinces and cities in our country have built a batch of professional cold storage, this system to perfect our country modern refrigeration technology played a promoting role.
Air conditioning cold storage, fruits and vegetables are active foods with respiration. To maintain high freshness and quality, they must inhibit the reproduction of microorganisms and their own physiological activities. If on the basis of the common cold storage of fruit and vegetable storage of gas composition according to certain standards for manual control, then can obtain better than ordinary refrigeration storage effect, it is called air refrigeration, hereinafter referred to as the CA cold storage.
Three-dimensional automatic cold storage, the so-called three-dimensional automation refers to the refrigerator, prefabricated insulated enclosure structure is adopted for the single cold storage with light steel production of multilayer high shelves, for pallets for storage, pallet loading depends on type of roadway stacker crane, according to the instruction of electronic computer in the house of the rolls in horizontal and vertical movement, can be removed from the specified goods, or into goods tray, and the cargo plane conveyor belt erosion &deposition behavior of automation. The top of the freezer is equipped with air cooler, which makes the upper space of the storage room to form a low temperature air layer, which is cooled by convection to maintain the temperature set in the reservoir.
With the rapid development of deep-sea fishery in China, especially the rise of tuna and fishing industry, the construction of "ultra-low temperature and cold storage" has made progress. In order to maintain the quality of the tuna and colour and lustre, frozen processing should be carried out immediately after capture (- 55 ~ 60 ℃) and 60 ℃ refrigerating storage.
