Sterilization principle
Ozone is a strong oxidant, and the sterilization process belongs to the biochemical oxidation reaction. There are three ways to sterilize O3:
Ozone can oxidize and differentiate the enzymes required for glucose inside bacteria, leading to their inactivation and death.
2. Directly interact with bacteria and viruses, damaging their organelles and DNA RNA， Damaging the emergence of bacteria and causing their death.
3. Through the arrangement of the cell membrane, it invades the cell and acts on the lipoproteins on the outer membrane and lipopolysaccharides inside, causing bacterial permeability distortion and dissolution.
Advantages - Non polluting disinfectant
Ozone sterilization is a lytic method that completely eliminates bacteria, leaves no residue, and has a broad-spectrum sterilization effect. It can kill bacterial colonies, spores, viruses, fungi, and can also damage botulinum toxin. Additionally, O3 also has a strong killing effect on mold. O3, due to its poor stability, quickly differentiates into oxygen or individual oxygen atoms, which can form oxygen molecules on their own without any toxic residues. Therefore, O3 is a pollution-free disinfectant. O3 is a gas that can quickly fill the entire sterilization space, eliminating any dead corners during sterilization.
Application in household and food categories
The domestic ozone technology is gradually becoming more sophisticated, and ozone is gradually becoming well-known to everyone because of its strong disinfection ability, which has replaced conventional disinfection and been applied in various fields:
1. Scope of living room and room air purification and disinfection: Ozone has the function of killing bacteria and viruses in the air, reducing dust, making the air fresh and natural, eliminating fatigue, and refreshing the mind.
2. The scope of preservation and disinfection of fruits and vegetables: The transportation and storage of fruits and vegetables have always been urgent issues that need to be addressed, and improper handling can lead to significant loss. It is reported that 30-40% of vegetables in China are stored improperly and partially stockpiled each year
And become waste. Ozone, together with negative ions, has excellent preservation properties for fruits and vegetables. Therefore, the use of ozone technology can greatly extend the preservation and storage time of fruits and vegetables, and expand their export scale. Other than that, ozone skills can also be used for
Sterilization and disinfection in vegetable processing.
3. Food occupational disinfection category: In the production process of beverages, fruit juices, etc., ozone water can be used for soaking and flushing pipelines, production equipment, and containers, and then reaching
The intention of disinfection and sterilization. There are three main applications in cold storage: firstly, killing microorganisms - disinfection and sterilization; The second is to oxidize and deodorize various odorous inorganic or organic substances; The third is to oxidize the new products and then suppress them
The process of innovation and innovation.
effect
The speed and effectiveness of ozone sterilization are unparalleled. Its high oxidation recovery potential determines its wide application in oxidation, decolorization, and deodorization. Some studies have shown that ozone dissolved in water can kill all harmful substances to the human body, such as iron, manganese, chromium, sulfate, phenol, benzene, oxides, etc. It can also differentiate organic matter and kill algae. Reaction between formaldehyde and ozone: 7O3 6COOH=3H2O 12CO2
The comparison between ozone disinfection and conventional sterilization methods has the following characteristics:
(1) Efficiency. Ozone disinfection and sterilization use air as coal material, without the need for any other auxiliary materials or additives. The body has good inclusiveness, complete sterilization, and strong anti mold, fishy, and odorous functions.
(2) High cleanliness. The rapid differentiation of ozone into oxygen is a common advantage of ozone as a disinfectant. Ozone is generated by using oxygen in the air. During the disinfection process, the remaining oxygen combines into oxygen molecules after 30 minutes, without any residue. This solves the problem of secondary pollution caused by disinfectant disinfection methods and eliminates the need for cleaning again after disinfection.
(3) Convenience. Ozone sterilizers are usually installed in clean rooms, air purification systems, or sterilization rooms (such as ozone sterilization cabinets, transfer windows, etc.). Based on the sterilization concentration and timing verified through debugging, set the opening and operating time of the sterilizer according to the timing, making it easy to operate and use.
(4) Economic viability. After comparing the application and operation of ozone disinfection and sterilization in many pharmaceutical professions and medical and health units, ozone disinfection method has significant economic and social benefits compared to other methods. In today's rapidly developing industry, environmental concerns are particularly important, and ozone disinfection avoids secondary pollution caused by other disinfection methods.
