Simple maintenance and methods of removing odor from the cold storage

Summary:Simple maintenance and methods of eliminating peculiar smell in the cold storage

A.The maintenance of the cold storage:

The addition of sterilization and sterilization of cold storage and sterilization of cold storage of raw materials and food contain a certain amount of fat, protein and starch. The existence of these nutrients, will make the mold and the growth of a large number of bacteria. To do a good job in the cold region of health management, to ensure quality of refrigerated food and cooking ingredients, to cold pundit sanitation and disinfection work regularly. The addition of mildew and mildew in cold storage can be used as an acid disinfectant.. The bactericidal effect of acid disinfectant is mainly the protein in the coagulation cell. Often some disinfectants have lactic acid, peroxide has acid, bleaching powder, Faure Marin, etc..

B.Methods of removing odor from cold storage

1.cold storage produce odor so-called odor, namely cold storage of cooking materials and food under the influence of external factors, through physical and chemical changes, resulting in an abnormal odor, after a considerable period of time, the smell on adhesion on the cold walls, ceilings and equipment and tools. Cold storage odor, generally speaking, the following reasons: the cold storage before the food is not a strange smell exists. The food before entering the cold storage has the phenomenon of spoilage, such as the rotten egg, meat, fish, etc.. Stored in the cold storage, the storage of meat, eggs, or fruits and vegetables and other food, resulting in the smell infection and deterioration. Cold storage ventilation is not free, temperature, humidity is too large, resulting in a large number of fungal breeding, mildew odor. The refrigerant (ammonia) erosion of the refrigeration pipe in the cold storage pipe causes the peculiar smell to produce.. The cold storage temperature does not drop, resulting in deterioration of corruption tainted meat flavor. This situation occurred in the frozen meat, frozen through transfer storage. There is a different smell of food in a warehouse, resulting in food infection and the taste of each other.

2.To prevent the cold storage of the method into the cold storage of food, must pass inspection, no deterioration of the warehouse can be stored. There is no smell in the warehouse before purchase. If there is a smell, must be technical treatment, the exclusion of odor can be used after the. Usually to strengthen the maintenance of refrigeration equipment, is strictly prohibited. Unloading, prevent pipeline caused by leakage of refrigerant so smashed. Food in the cold process, must keep the warehouse to maintain a certain temperature, and can not freeze the food to carry a library or storage. If the warehouse temperature drop down, should find the reason, to be excluded after the food processing. Stored in the freezer can not mix the food infected with each other.

3.Methods of ozone removal for cold storage. Ozone has a strong oxidation, not only can eliminate the warehouse odor, but also to stop microbial growth. Use ozone generator, can realize the exclusion of the warehouse odor. If cold storage memory containing more fat food, you should not use ozone treatment to avoid fat oxidation and rancidity phenomenon. Formaldehyde. The cold storage in the warehouse the goods out, with 2% formaldehyde aqueous solution (i.e. formalin solution) for disinfection and odor elimination. Vinegar method. Fish with refrigerated storage, the smell of fish is very heavy. Not with other food, must be thoroughly cleaned out the smell of fish before they can mount the other food. General remove fishy method is vinegar. Specific methods: fish out of cold storage, the evaporating pipe of frost layer clean, and maintain the storage temperature of 50 DEG C, and press for every cubic meter volume of the cold storage warehouse with vinegar Volume 50 - 100 grams of preparation, spray to the library injection, the first warehouse door closes tightly, intermittently operated blower, let the volatilization of vinegar and flows in a library, the vinegar absorb a large number of fish smell. General after about 4 - 24 hours after the cold storage door open, continuous blast hours can be blown out outside the vinegar.

B.The maintenance of the cold storage:

1.After cold storage installation is finished, or long-term disabled again, cooling speed should be reasonable: every control in the 8-10 deg.C is appropriate, in 0 deg.C should be kept for a period of time.

2.The maintenance of cold storage reservoir, attention to the collision and scratch of the hard object to the reservoir body. Because of the depression and corrosion of the reservoir plate, the local heat preservation performance of the reservoir can be reduced seriously.

3.Cold sealing parts maintenance of cold storage, because the refrigeratory assembled by a plurality of insulation board together, so in between exist a certain gap, the construction of the gap will be sealed with sealant, to prevent the entry of air and water. So in the use of some of the seal failure site repair in time.

4.Cold storage ground maintenance, general small and medium-sized assembling cold store ground use insulation board, cold should prevent the ground being large quantities of ice and water. If there are ice, clean cut do not use rigid thing.no, damage to the ground.
