Main points of removing peculiar smell in cold storage
1. Key ozone method for removing odor in cold storage.Ozone has a fierce oxidation dye, not only can eliminate the odor of the cold storage room, but also can avoid the development of microorganisms.Recovery ozone generator, can realize the removal of the smell of the warehouse.If the food containing more fat is stored in the cold storage, it is not appropriate to recycle ozone treatment reward and punishment, so as to avoid fat oxidation and rashing signs.Formaldehyde method.Remove the goods from the refrigerated storage room, sterilize with 2% formaldehyde solution (formalin solution) and remove the odor.The vinegar.The refrigerated storeroom where the fish had been stored had a strong smell.Should not be loaded with the rest of the food, must be thoroughly washed to remove the smell of fish before loading the rest of the food.As usual, the key to get rid of fishy smell is to recycle vinegar.After detailed main point is: the fish out of the cold storage, breaks the evaporation tube group of frost layer on clean, and keep the warehouse under the temperature of 50 ℃, and then press the cold storage warehouse prepared with vinegar amount 50100 grams per cubic meter volume, to the rolls with spray jet, warehouse door closed precision first, off and on to start the blower, let the vinegar volatilization and in the house of the rolls, plenty of the vinegar will receive fishy smell.As usual after about 424 hours to open the door of the cold storage, continuous air blowing hours can be vinegar taste out of the storage.
