The use of simple cold storage service and maintenance and removal of odor metho
Maintenance of Cold Storage 1, cold storage addition to sterilization and disinfection mold cooking frozen raw and cold storage Food Both contain some fat, protein and starch. The existence of these nutrients will lead to the growth of mold and bacteria multiply. To make cold She health management, food and cooking to ensure the quality of raw materials, refrigeration, cold She would regularly carry out health disinfection. In addition to cold storage to kill mold and disinfect mold, can first use of acid Disinfectant . Acid disinfectant bactericidal action, mainly in solidification cell protein. Common disinfectants are lactic acid and peroxide have been acid, bleaching powder, formalin, etc..
Second, cold storage method to exclude odor
1, cold storage of the reasons for the so-called odor smell, that cold storage of cooking ingredients and foods under the influence of external factors, through the physical and chemical changes, resulting in an abnormal smell, constant, daily, that smell on the stick attached to the refrigerator walls, ceilings and equipment and tools. Cold storage in odor, in general there are several reasons for this: into the cold without food before there exists a kind of smell. Into cold storage before the food there is the phenomenon of corruption and degeneration, such as the deterioration of eggs, meat and fish. Cold storage than fish without cleaning or storing of meat, eggs, or fruit and vegetables and other foods, resulting in deterioration smell of infection. Cold and poor ventilation, temperature and humidity is too large, resulting in large population of mold, mildew odor produced. Cold Storage Refrigeration Pipeline leaks, Refrigerants (Ammonia) smell caused erosion to produce food. Cold temperature does not drop, resulting in meat spoilage taste of corruption. This mostly occurs in meat is not frozen, frozen storage library through the turn. There is a different smell of food cold storage warehouse, leading to cross-infection of food odor.
2, to prevent the odor of the method into the cold storage cold storage cold storage of food, must be tested, there is no deterioration of the storage be stored. Cold storage warehouse may not have smell in there before purchase. If smell, must be technical processing, remove odor before using. Usually necessary to strengthen the maintenance of refrigeration equipment, non-inverted stack discharge to prevent the pipeline so smashed, causing refrigerant leakage. Food in the cold process, cold storage warehouse must maintain a certain temperature, the system may not be frozen or stored food to turn libraries. If the cold storage warehouse temperature drop is not over, should find the cause, be ruled out before making food processing. Shall not be mixed within the cold storage of food and cross-infection.
3, cold storage method of excluding ozone smell. Ozone has a strong oxidation, cold storage warehouse can not only eliminate odors, but also to stop the growth of microorganisms. Use of ozone generators, odor can be realized on the Treasury's rule. If the cold storing foods containing more fat, then not using ozone treatment, to avoid the phenomenon of fat oxidation and rancidity. Formaldehyde method. Will move out of cold storage of goods within the Treasury, with 2% formaldehyde aqueous solution (ie, formalin) for disinfection and removal of odor. Vinegar method. Installed over the fish of the cold storage warehouse, heavy smell of fish. Other foods should not be installed, have to thoroughly cleaned before it can rule out the smell of fish into other foods. General approach is to remove the fish smell with vinegar approach. Specific methods are: fish out of cold storage, will be frost on the evaporator tube group layer clean, and maintain temperature in the warehouse?? 50 below, then press the cold storage warehouse used for each cubic meter volume of vinegar is 50? 100 grams of the preparation, use sprayer jet to the database, first library door shut tight, and off switch on drum Fans So volatile and the bank liquidity vinegar to vinegar absorbs the fish smell. Usually about after 4? 24 hours after the cold garage door open, continuous blast vinegar can blow a few hours outside the library.
Maintenance of cold storage 1, cold storage after installation or long-term suspended again, cooling rate must be reasonable: a day at 8-10 suitable control, should be maintained at 0 for some time.
2, cold storage library board maintenance, attention should be noted that the use of hard objects on the storage body collision and scratching. Because depression can cause library board and corrosion will seriously reduce the insulation properties of the Local Library.
3, cold sealing parts and maintenance, as fabricated cold insulation board by a number of assorted pieces, so there is a certain gap between the plates, the construction of these cracks will be sealed with a sealant to prevent air and moisture to enter. Therefore, in use in some parts of seal failure timely repair.
4, cold ground maintenance, general small-scale assembly-ground use of cold storage insulation board, use the refrigerator to prevent the ground there should be a lot of ice and water, if there is ice, clearing a hard object when the tap must not be used, damaged the ground.
