Summary Ozone (O3), with its peculiar smell and its name, it is the oxygen (O2) allotropes, composed of three atoms of oxygen. Ozone has strong oxidation, the oxidation reduction potential after fluoride, ranking the second place, after sterilization quickly decomposed into oxygen (O2), does not produce residual pollution; at the same time, ozone has a high energy, under normal temperature and pressure, very fast decomposition for oxygen (O2) and a single oxygen atoms (o). It is precisely because of the strong oxidation and instability of ozone in the food industry, with ozone as a disinfectant to disinfect, deodorant, deodorant, has been more and more widely used.
In developed countries, ozone has been widely used in food processing, beverage production, ocean transportation and food and beverage industry and other industries. In our country, the ozone utilization rate is low, start late, but with people's understanding of the ozone, the application of ozone sterilization will become the food industry, especially the export of food industry. Aozongmaikesi device Co., Ltd. is the production of ozone generator can be widely used in the food industry space disinfection; preparation of ozone water can be used for water purification, bottled water sterilization, aquaculture, removal of pesticide residues etc.
The superiority of ozone sterilization
The shortcomings of traditional methods of disinfection and sterilization: in the food industry, the traditional methods of disinfection and sterilization in most of the ultraviolet light irradiation, chemical reagents wipe or spray method. Application of ultraviolet irradiation, ultraviolet lamp efficacy will be decreased with the increase of time; ultraviolet light radiation effect to sterilization, food processing workshop was very high, irradiation intensity and distance is inversely proportional to the square, only exposure to position and reach the standard irradiation only bactericidal effect, strength is not enough. Therefore, it is of large dead; bactericidal action with different strains and different, such as killing mold exposure to than kill bacteria increased from 40 to 50 times; at the same time, the humidity on the sterilization effect influence, ultraviolet sterilization in 60% relative humidity of the effect of a sharp decline in, more than 80% humidity time reversal can induce bacterial resurrection.
Cleaning and disinfectant spraying with chemicals, always in the cleaning and disinfection, disinfection after again clean, waste a lot of manpower and material resources, quite troublesome also can produce residual contamination, and the need for ventilation or chemical neutralization, trouble and reduce the disinfection effect
Compared with the traditional methods, the application of ozone for disinfection and sterilization, and has the advantages that cannot be replaced by other disinfection methods: (1) the bactericidal ability than other disinfectants. The ozone will decompose into oxygen, does not have two pollution, without ventilation after disinfection. And ozone gas, good diffusion, no dead angle, uniform concentration. The ozone can be directly used for food, for sterilization or disinfection antiseptic, dry, easy. Ozone bactericidal concentration of food is very weak oxidation concentration, harmless to food. The ozone in the water sterilization speed fast (faster than chlorine 300-600 times), chlorine to kill not kill the virus I cysts, such as Cryptosporidium. The better the humidity is high bactericidal effect on the food industry, 80%-90% is especially suitable for high humidity environment. , food processing workshop installation ozone equipment investment and the UV lamp (according to 16-18 cubic meters installed a 30W ultraviolet lamp design standard), and operating costs due to ozone equipment saving, long service life and greatly reduced, for new workshop.
In summary, ozone is a broad spectrum, high efficiency gas fungicide, reliable, economical and practical, with its
It can not replace the role of disinfectant, and its unique efficacy has been increasingly favored by the people. At present, has been widely used in food processing workshop sterilization purification, environmental sterilization and disinfection work clothes, food flavor in addition to purifying, aquaculture, frozen food processing, mineral water sterilization durability, water for food production, seafood sterilization and preservation, frozen meat, cold storage disinfection and fresh fruits and vegetables on, to solve the problem of the part of food export enterprises production in microbial breeding is difficult to control.
