How to dispel the smell in cold room?

Views: 9201/13/2020  

Methods of dispelling the smell in cold room for fruits and food:

1. What is peculiar smell in the cold room? That is under the influence of external factors, the cooking materials and food in the cold storage produce an abnormal smell through the change of physical chemistry, which will stick to the wall, ceiling, equipment and tools of the cold storage for a long time. In general, there are several reasons for the peculiar smell in the cold storage: there is a peculiar smell in the cold storage before entering the food. Before entering the freezer, the food will be rotten, such as rotten eggs, meat, fish, etc. The refrigerated storehouse where fish have been stored and meat, eggs, fruits and vegetables, and other foods have been stored without cleaning, resulting in odor infection and deterioration. The cold room for seafood is not well ventilated, and the temperature and humidity are too high, which results in a large number of mold reproduction and odor. Due to the leakage of the refrigeration pipeline in the cold storage, the refrigerant erodes into the food, resulting in a peculiar smell. The temperature in the cold storage does not drop, resulting in the deterioration of meat and putrefaction. This happens when fresh meat is not frozen or frozen completely. Food with different smell exists in cold storage, which leads to the mutual infection of food strings.

2. The method to prevent the peculiar smell of the cold store: the food that enters the cold store for refrigeration must pass the inspection, and the food that does not go bad can be put into storage. There shall be no peculiar smell in the cold storage before purchase. If there is a peculiar smell, it must be treated by technology and can be used only after the peculiar smell is eliminated. Generally, it is necessary to strengthen the maintenance of the refrigeration equipment. It is strictly prohibited to dump and unload, to avoid damaging the pipeline and causing refrigerant leakage. In the process of cold processing, the cold storage must be kept at a certain temperature, and frozen food shall not be transferred or stored. If the temperature in the cold storage can not be reduced, the cause shall be found out and the food processing shall be carried out after elimination. Do not mix and store the food infected with each other in the cold store.

3. The ozone method is used to eliminate peculiar smell in cold storage. Ozone has a strong oxidizing effect. It can not only eliminate the peculiar smell of cold storage but also stop the growth of microorganisms. The ozone generator can eliminate the peculiar smell in the warehouse. If there is more fat in the cold storage, it is not suitable to use oxygen treatment to avoid rancidity caused by fat oxidation. Formaldehyde method. Remove the goods from the cold storage, disinfect and remove the peculiar smell with a 2% formaldehyde solution (i.e. formalin solution). Vinegar method. It's a refrigerated warehouse filled with fish. It's fishy. It is not suitable to pack other food. It is not allowed to pack other food until the fishy smell is completely eliminated. Generally, vinegar is used to remove the fishy smell. The specific method is: after the fish comes out of the cold storage, clean the frost layer on the evaporating pipe group and keep the storehouse temperature below --50 degrees Celsius, then makeup 50-100 grams of vinegar with each cubic meter volume in the cold storage warehouse, spray it into the storehouse with a sprayer, close the storeroom door first, and intermittently start the blower, so that the vinegar evaporates and flows in the storehouse, which makes the vinegar absorb a lot of fish smell. Generally, after 4-24 hours, open the door of the cold storage, and continuously blow for several hours to blow the vinegar out of the warehouse.
