Decontamination industry information
Ozone generator fumigation sterilization technology is a strong oxidant that can destroy the chemical bonds of organic molecules, causing them to lose their biological activity, thus achieving the goal of disinfection and sterilization. Ozone generator fumigation sterilization technology can be widely applied in water treatment, air purification, waste gas treatment and other fields, and also has important applications in food processing, medical and health, animal husbandry and other fields. The ozone generator fumigation sterilization technology can be achieved in two ways: one is to directly spray the ozone generator fumigation sterilization technology from air or oxygen into the area to be disinfected, and the other is to dissolve ozone in water to form ozone water and spray it into the area to be disinfected. The former is mainly used for air disinfection, while the latter is suitable for surface disinfection and water treatment. In meat product factories, ozone generator fumigation sterilization technology usually disinfects the surface. After dissolving ozone in water, ozone water is sprayed onto the surfaces of meat product production workshops, processing equipment, tableware, and other surfaces through spraying, achieving the purpose of disinfection and sterilization. Compared with traditional disinfection methods, ozone sterilization technology has the following advantages:
Improving the application of ozone generator atomization disinfection technology in clean vegetable food
In recent years, more and more people have begun to pay attention to health and food safety issues, and “clean vegetables” have become a new choice for consumers to pursue a healthy diet. Clean vegetable refers to a new type of vegetable product that utilizes scientific technology to process, treat, or preserve vegetables, achieving the goals of sterilization, pest control, mold removal, deodorization, and preservation. As a new type of vegetable purification technology, ozone disinfection technology is gradually being applied to the sterilization, preservation, and purification processes of vegetables. Ozone technology is the process of ionizing, electrochemically, or other means to produce a certain amount of ozone generator atomized disinfection gas in the air, which is used for sterilization, disinfection, and purification. Ozone gas can quickly oxidize and decompose organic matter, kill bacteria, viruses, fungi and other microorganisms, and purify air and water sources. Applying ozone technology to the treatment process of vegetables can effectively remove residual pesticides, fertilizers, bacteria, molds and other harmful substances on the surface of vegetables, achieving the effects of preservation, sterilization, and purification. The application of ozone technology in clean vegetable food can not only improve the quality of vegetables, but also effectively improve the
Ozone, with the chemical formula O3, is an allotrope of oxygen that can quickly kill most pathogenic bacteria, fungi, viruses, and other microorganisms. Ozone disinfection technology has a strong redox effect and can kill bacteria in both water and air. Its bactericidal principle is to use the strong oxidizing properties of ozone molecules to kill microorganisms through oxidation membranes, broken bacterial cell membranes, inhibition of enzyme and protein synthesis, and other methods.
Disinfectants should not be used to disinfect air with people in the environment. During disinfection, unrelated personnel should evacuate the site. When disinfecting the air, the doors and windows should be sealed. After disinfection, the indoor disinfectant should be reduced to no impact on people before entering. If possible, windows can be opened for ventilation to allow the disinfectant to spread and neutralize as soon as possible. Disinfectants such as peroxyacetic acid, chlorine dioxide, hydrogen peroxide, etc. are corrosive to metal items, have a bleaching effect on fabrics, and ozone can damage rubber products. When disinfecting, efforts should be made to avoid disinfectants directly acting on these items. When fumigating and disinfecting, attention should be paid to fire prevention and preventing burns. Diluted solution should be prepared and used immediately.
Folding aerosol spray disinfection When spray, close the doors and windows, and the operator holds the nozzle in the air, evenly spraying from inside to outside, from top to bottom, and from left to right. After the predetermined time, open the doors and windows to remove residual disinfectant particles from the air. Folding heating fumigation disinfection method Place the disinfectant solution in a container on the heating source, close the doors and windows, connect the heating source, and after the disinfectant is fumigated, turn off the heat source. After a predetermined time, open the window for ventilation (about 30 minutes). If the indoor relative humidity is low during fumigation, a certain amount of water can be sprayed to increase the indoor relative humidity.
Requirements for folding physical and chemical indicators The physical and chemical indicators such as the content of effective ingredients and pH value of disinfectants should comply with relevant standards for product quality. Peroxyacetic acid should comply with GB 19104, and hydrogen peroxide should comply with the requirements of GB 1616. Stability requirements: The effective ingredient reduction rate of liquid disinfectants within the product validity period should be ≤ 15%; The decrease rate of effective ingredient content of solid disinfectants within the product’s validity period is ≤ 10%. The residual toxicity after disinfection and in the environment should comply with the requirements of relevant national standards and regulations. During the disinfection process, it is not prone to combustion, explosion Requirements for folding to kill microorganisms In laboratory sterilization test or disinfection simulation field test, when aerosol spray method is used for disinfection, the amount of disinfectant shall be ≤ 10 mL/m. Under the conditions of 20 ℃~25 ℃ and relative humidity of 50%~70%, the effect is ≤ 1 hour. The killing rate of Staphylococcus aureus in the air should be ≥ 99.9%. Under natural conditions on site, when aerosol spray method is used for disinfection, the amount of disinfectant shall be
