Let the refrigeration unit editor tell you about it.

1、 Methods to prevent odors from occurring in cold storage units. Cold storage must not have any odor before procurement. If there is any odor, technical treatment should be carried out before use to deal with the odor. The refrigerated food entering the cold storage must undergo inspection to ensure that no spoiled products can be stored. Usually, it is necessary to strengthen the maintenance and upkeep of cold storage and equipment inside the cold storage. It is strictly prohibited to dump goods to prevent damage to the management and walls of the cold storage, which may cause abnormal accidents such as refrigeration failure or air conditioning leakage. During the cold processing of refrigerated food, the refrigerated container room should maintain a certain temperature and should not transfer or store frozen food. If the temperature in the refrigerated garage cannot be lowered, the cause should be identified and eliminated before proceeding with food processing. Foods that are mutually infected must not be mixed and stored in cold storage.

2、 Acidic agents can be used to remove mold and kill bacteria in cold storage. The bactericidal effect of acidic agents is mainly to solidify proteins in microorganisms. Commonly used agents include lactic acid, peracetic acid, bleach, formalin, etc.

3、 Methods for handling odors in cold storage. The cold storage, already filled with fish, has a strong fishy smell. It is not advisable to package other foods to avoid contamination by odors. Before loading other food, it is necessary to clean it to remove the fishy smell. The general method to remove fishy odor is to use vinegar. The specific method is: after the fish leave the cold storage, clear the frost layer on the evaporation tube group to keep the temperature of the cold storage at normal temperature, then spray the room with vinegar spray, and then close the cold storage door. After one hour, open the door again, turn on the cold storage fan, and let the cold storage fan generate air to exhaust all the air with odor inside the cold storage. Until there is no odor. Formaldehyde method can also be used to remove refrigerated food in cold storage, and formaldehyde solution, also known as formalin solution, can be used to treat odors. Ozone can also be used to treat odors. Ozone has a strong oxidizing effect, which can not only treat odors in warehouses, but also prevent the growth of microorganisms. Ozone generators can be used to treat odors in warehouses.
