Ozone disinfection equipmentMainly used for air sterilization and surface sterilization in processing workshops and similar places for food, drugs, cosmetics, etc. Ozone disinfection machines can be divided into mobile, wall mounted, pendant light, floor standing, etc. according to their installation forms. When ozone disinfection equipment is used in pharmaceutical GMP workshops and HVAC systems, it is usually divided into two types: built-in and external. The machine that uses an ozone generator to produce ozone is called an ozone disinfection machine, where ozone is used as a disinfectant.
The sterilization principle of ozone disinfection equipment:
Ozone is a strong oxidant, and the sterilization process belongs to biochemical oxidation reactions. There are three forms of O3 sterilization:
Ozone can oxidize and decompose the enzymes required for glucose inside bacteria, leading to their inactivation and death.
Directly interacting with bacteria, damaging their organelles, DNA, and RNA, disrupting their metabolism and leading to bacterial death.
Through the cell membrane tissue, it invades the cell and acts on the lipoproteins on the outer membrane and lipopolysaccharides inside, causing bacterial permeability distortion and dissolution death.
The sterilization advantages of ozone disinfection equipment:
Ozone sterilization is a lytic level method, with no residue, broad-spectrum, and can kill bacterial colonies, spores, fungi, etc. It can also destroy botulinum toxin. In addition, O3 has a killing effect on mold. Due to its poor stability, O3 quickly decomposes into oxygen or individual oxygen atoms, and individual oxygen atoms can combine to form oxygen molecules without any toxic residues. Therefore, O3 is a pollution-free disinfectant. O3 is a gas that can quickly diffuse throughout the entire sterilization space for sterilization. However, traditional sterilization and disinfection methods, whether it is ultraviolet radiation or chemical fumigation, have disadvantages such as lack of efficacy, dead corners, large workload, residual pollution or odor, and may harm human health. If ultraviolet disinfection is used, it has no effect in areas where light cannot reach, and has disadvantages such as decay, weak penetration, and short service life. The chemical fumigation method also has shortcomings, such as the ineffective treatment of bacteria with strong resistance to drugs.
The sterilization and disinfection effect of reactive oxygen species (ozone) is reflected in its strong oxidizing properties, making it a green and broad-spectrum disinfectant. Widely used for disinfection of drinking water and air in medical and health institutions, ozone will automatically reduce to oxygen after 30-40 minutes, without any chemical residue or secondary pollution. The fields of application include disinfection cabinets, fruit and vegetable machines, gynecological treatment equipment, food processing, drinking water filling and disinfection equipment, etc. Details can be verified by consulting popular science books or searching online.
