Cold storage:
Foods containing a certain amount of fat, protein, and starch are generally stored in cold storage. The growth and reproduction of molds and bacteria are due to the presence of these nutrients.

Therefore, for hygienic treatment and to ensure the quality of the ingredients stored in the cold storage, regular cold water hygiene and disinfection work should be carried out. Acid disinfectants can be used for mold removal and disinfection in cold storage. The bactericidal effect of acid disinfectants mainly coagulates the protein in bacteria. Commonly used disinfectants include lactic acid, peroxyacid, formalin, etc.
II. Methods to eliminate peculiar smells in cold storage:

Reasons for peculiar smells in cold storage. The so-called peculiar smell refers to an abnormal peculiar smell produced by cooking materials and foods in cold storage through physical and chemical changes under the influence of external factors. Over time, this smell will adhere to the walls, ceilings, and items in the cold storage.
Before food in cold storage is put into storage without spoilage, it needs to be inspected.
Eliminate peculiar smells in cold storage by ozone method. Ozone with strong oxidation effect can not only effectively remove the peculiar smell in the cold storage, but also prevent the growth of microorganisms. If there is a lot of high-fat food in the cold storage, do not use ozone treatment to avoid rancidity caused by fat oxidation.
Cold storage maintenance:
The cold storage should be used again after installation or a long-term interruption, and the cooling speed should be reasonable.
When repairing cold storage panels, pay attention to avoiding collisions and scratches on the storage body when using hard objects. Because it will cause depressions and corrosion of the storage panels, which will seriously reduce the partial insulation function of the storage.
Protection of sealed parts of cold storage. Since the assembled cold storage is composed of several insulation panels, there is a certain gap between the panels. During construction, sealant will be used for sealing to prevent air and moisture from entering.
Therefore, some parts with seal failure should be repaired in time during use.
Protection of the cold storage floor.
The floor of a small assembled cold storage is generally made of insulation panels. When using the cold storage, avoid a large amount of ice and accumulated water on the ground. If there is ice, do not knock with hard objects when cleaning to avoid damaging the ground.
