What is the principle of ozone disinfection cabinet?
Ozone disinfection cabinet
Ozone disinfection cabinet uses the strong oxidation of ozone for antiviral treatment. Ozone is a blue explosive gas at room temperature and has a special smell. It is one of the strongest oxidants known and a broad-spectrum bactericide. However, ozone leakage will do harm to our health, and the allowable threshold in workplace air is 0.2mg/m3. Therefore, ozone disinfection cabinet needs to keep the ozone concentration in the cabinet, ensure the disinfection effect and ensure that the ozone does not leak.
Ozone plus ultraviolet disinfection cabinet
Ozone plus ultraviolet disinfection cabinet is a kind of disinfection cabinet, which uses ultraviolet and ozone as disinfection methods. The ultraviolet lamp used for disinfection and sterilization should be a high ozone ultraviolet lamp. The wavelength range of ultraviolet rays is 200-275 nm, and the band with the strongest bactericidal effect is 250-270 nm. Ultraviolet light has low energy and weak penetration. It can only kill directly irradiated microorganisms. Therefore, the disinfection site must be completely exposed to ultraviolet rays during disinfection. The ultraviolet lamp also produces ozone, which plays a role in sterilization.
Electric disinfection cabinet
Electric sterilizers use high temperature to play an antiviral role, and high temperature has a fatal effect on bacteria. Protein in bacteria is denatured and solidified by heat, its activity disappears, and its metabolism is blocked, leading to death. The disinfection temperature of the electric disinfection cabinet is ≥ 100℃, and the disinfection time is ≥ 15 minutes.
How to use ozone disinfection cabinet?
1, when using the disinfection cabinet, be sure to clean the tableware before putting it into the disinfection cabinet for disinfection, which can shorten the disinfection time and reduce power consumption.
2. High-temperature tableware should not be placed in a lower high-temperature disinfection cabinet, but a low-temperature disinfection cabinet should be placed above ozone disinfection cabinet for disinfection to avoid damaging tableware.
3, colored porcelain in the disinfection cabinet will release harmful substances, endangering human health. So be sure not to put these colored porcelain in the disinfection cabinet. Under the working condition, the internal temperature of the sterilizer can be as high as 200 C. Often putting food in these sterilized colored porcelain will pollute food and endanger health.
4. Bowls, plates, cups and other tableware should be placed vertically on the shelf, and it is best not to stack them, so as to ventilate and disinfect as soon as possible.
5. When using ozone disinfection cabinet, please pay attention to whether the ozone generator works normally. If you don't hear the sound of high-voltage discharge or see the blue light of discharge, the ozone generator may fail and should be repaired in time.
6, disinfection cabinet should be placed in a dry and ventilated place, not less than 30CM away from the wall.
7, disinfection does not need to open the door, so as not to affect the effect.
8. After disinfection, if you take it ten minutes later, the effect will be better. When the door is opened, a small amount of ozone odor will overflow. This concentration is harmless to human health, please rest assured.
9. Wipe the water in the water tank at the lower end of the cabinet regularly.
Is ozone disinfection cabinet harmful?
1. Ozone is a gaseous oxidant, and its sterilization process is strong oxidation, which makes various components in microbial cells react, thus causing irreversible changes and death. Ozone inactivation of viruses is achieved by directly destroying their ribonucleic acid or deoxyribonucleic acid species. It is ozone that first acts on the cell membrane to kill bacteria and mold microorganisms, which leads to the damage of membrane components, metabolic disorder and inhibition of its growth. Ozone continues to penetrate and destroy the membrane tissue until it is killed. The increase of humidity will increase the killing rate, because the cell membrane will swell and thin under high humidity, and its tissue will be easily destroyed by ozone.
2. If the ozone concentration in human body is kept above 3mg/m3, people will suffer from respiratory diseases. However, if a small amount of ozone leakage is short-lived, it is harmless to the human body and has the function of purifying the air. Because ozone will be reduced by oxygen within three minutes after it meets air. Therefore, when the disinfection cabinet works (about 30 minutes), it can smell the faint ozone smell. After disinfection, the ozone smell will disappear automatically. F299 disinfection cabinet adds negative ion disinfection function while ozone disinfection, which makes ozone smell lighter, and even has peculiar smell.
