¡¡ Food processing, cold storage and disinfection ozone odor removal application technology ¡¡ Gas ozone as efficient, broad-spectrum, no residual disinfectant gas pollution, food industry than the commonly used chemical disinfectants such as: peracetic acid, potassium permanganate, formaldehyde (formalin), sulfur dioxide (sulfur fumigation) and other phase ratio, the effect is particularly advantageous. Ozone itself points Decomposed into oxygen without residual contamination after disinfection does not require ventilation. Ozone and ultraviolet germicidal irradiation, compared with the proliferation of good, uniform concentration, no dead ends and other characteristics, and UV irradiation is not the place for no bactericidal effect. In more than 60% relative humidity, ultraviolet germicidal effect falling sharply, more than 80% humidity can induce anti-bacterial resurrection. Under normal circumstances, aquatic products processing plant and storage compartment humidity relatively large, while the humidity, the greater the use of ozone sterilization, the better the food processing industry, 80% to 90% of high-humidity environment, especially suitable. 1, cold sterilization, biological pollution is mainly cold mold, because at low temperatures on the survival of a strong disinfectant tolerance. Biotechnology Research Institute, Lanzhou University, Gansu and cooperation, Lanzhou Penicillium cold storage as a disinfectant screening test, formaldehyde, peracetic acid, warehouse tall oil and ozone disinfection comparison preferred the ozone. 12ppm role in ozone for 3 - 4 hours, including a strong resistance germinating spores are not killed. Refrigerator deodorant application of ozone is very effective, short time to be effective. Whampoa Guangzhou, a refrigeration plant using ozone to remove the smell of fish deterioration, one hour to complete. Chengdu, a refrigerator with ozone to remove the stench of fish after a storage repository of good quality ice cream, other disinfectants are below standard. 2, food processing plant sterilization purification, frozen food, aquatic products processing and packaging workshop, have a relatively high hygiene requirements, production workshop microbial pollution is a very important factor in the quality of products. Most of the current domestic processing plant using UV light disinfection, sterilization as UV and shortcomings, processed microbial indicators are difficult to control, particularly severe in the summer. Ozone disinfection processing plant works well for the general use of 0.5-1.0 ppm can reach more than 80% of the sterilization rate, and can effectively remove odor workshop. Original factory in Tianjin's foreign trade frozen, processed seafood, sausage and smell serious workshop, use the odor of ozone is very effective start one hour a day, the bacteria kill rate of 91. 3% rate of qualified products increased significantly. Refrigeration Plant Yantai Foreign Trade for many years in processing. Packaging workshop and changing use of ozone disinfection to ensure that the plant health conditions, and improve the quality of aquatic products processing. 3, the use of ozone disinfection apparatus for overalls and processing, very effective easy. Especially for clothes disinfection, does not produce a result of high temperature high pressure steam sterilization of cotton produced after the clothes from white to yellow, fiber damage and shedding phenomenon. Not only thorough disinfection, but also prolong life.
