Cold storage is mainly used for constant temperature storage refrigerator equipment for food, dairy products, meat, aquatic products, etc. The cold storage is actually a kind of low-temperature cold storage (refrigerator) and also belongs to a kind of refrigeration equipment, with a large refrigeration area. Since it is stored food, it will inevitably have some odors after using it for a long time. Let's take a look at the ways to eliminate odors in the cold storage! 1. Reasons for peculiar smell in the cold storage The peculiar smell in the cold storage refers to: the cooking raw materials and food in the cold storage will produce an abnormal smell through physical and chemical changes under the influence of external factors.

Cold storage is mainly used for constant temperature storage refrigerator equipment for food, dairy products, meat, aquatic products, etc. The cold storage is actually a kind of low-temperature cold storage (refrigerator) and also belongs to a kind of refrigeration equipment, with a large refrigeration area. Since it is stored food, it will inevitably have some odors after using it for a long time. Let's take a look at the ways to eliminate odors in the cold storage! 1. Reasons for peculiar smell in the cold storage The peculiar smell in the cold storage refers to: the cooking raw materials and food in the cold storage, under the influence of external factors, produce an abnormal smell through physical and chemical changes. Over time, this smell will stick. Attached to the walls, ceiling and equipment and tools of cold storage. Generally speaking, there are the following reasons for the peculiar smell in the cold storage: There is a strange smell in the cold storage before the food is put into it. Before the food is put into the cold storage, there is a phenomenon of spoilage, such as spoiled eggs, meat, fish, etc. Foods such as meat, eggs, or fruits and vegetables are stored in the cold storage where fish has been stored without cleaning, resulting in odor infection and deterioration. The cold storage is poorly ventilated, and the temperature and humidity are too high, resulting in a large number of molds and a moldy smell. The leakage of the refrigeration pipeline of the cold storage, the corrosion of the refrigerant (ammonia) into the food causes the generation of peculiar smell. The temperature in the cold storage does not drop, causing the meat to deteriorate and produce a rotten smell. This situation mostly occurs when the fresh meat is not frozen, and it is transferred to the warehouse for storage. Foods with different smells are stored in a cold storage warehouse. 2. The method of eliminating peculiar smell in cold storage Ozone method. Ozone has a strong oxidizing effect, which can not only eliminate the odor of cold storage warehouses, but also prevent the growth of microorganisms. The ozone generator can be used to eliminate the odor in the warehouse. If food with more fat is stored in the cold storage, it is not suitable to use ozone treatment to avoid the phenomenon of rancidity caused by fat oxidation. Formaldehyde method: move the goods out of the cold storage warehouse, and use 2% formaldehyde solution (i.e. formalin solution) to disinfect and eliminate odors. Vinegar method: The cold storage warehouse where the fish has been installed has a strong fishy smell. It should not be loaded with other food. It must be thoroughly cleaned to remove the fishy smell before loading other food. The general way to remove the fishy smell is to use vinegar. 3. Methods to prevent the occurrence of peculiar smell in the cold storage The food that is refrigerated in the cold storage must be inspected, and the food that has not deteriorated can be stored in the storage. The cold storage warehouse must not have peculiar smell before purchasing. If there is peculiar smell, it must undergo technical treatment to eliminate the peculiar smell before use. Usually, it is necessary to strengthen the maintenance of refrigeration equipment, and it is strictly forbidden to dump and unload the goods to prevent the pipeline from being smashed and the refrigerant leaking. During the cold processing of food, the cold storage room must be kept at a certain temperature, and frozen food must not be transferred or stored. If the temperature of the cold storage warehouse cannot be lowered, the reason should be found and the food processing should be carried out after the exclusion. Foods that are infected with each other shall not be mixed and stored in the cold storage. With these little common sense, we no longer have to worry about annoying odors in the cold storage!
