What is the principle of disinfection cabinet?
(1) disinfection cabinet principle-ozone disinfection cabinet:
In fact, ozone disinfection cabinet is using the strong oxidation of ozone to kill the virus. Ozone is a bluish explosive gas with a special smell at room temperature. 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 value in workplace air is 0.2mg/m3. Therefore, ozone disinfection cabinet should keep the concentration of ozone in the cabinet to ensure the disinfection effect under the condition that ozone does not leak.
(2) disinfection cabinet principle-ozone plus ultraviolet tableware disinfection cabinet:
About ozone plus ultraviolet tableware disinfection cabinet is a disinfection cabinet using 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 strongest bactericidal band is 250 ~ 270 nm. Ultraviolet rays have low energy and weak penetration, and can only kill directly exposed microorganisms. Therefore, the disinfection site must be fully exposed to ultraviolet rays during disinfection. The ultraviolet lamp also produces ozone, which also plays a role in sterilization. (3) disinfection cabinet principle-electric disinfection cabinet:
For the electric disinfection cabinet, high temperature is used to sterilize. High temperature is fatal to bacteria. Protein in bacteria is denatured and solidified by heat, and its activity disappears, leading to metabolic disorder and death. The disinfection temperature of the electric sterilizer is ≥ 100℃, and the disinfection time is ≥ 15 minutes.
What's the use of the boss's disinfection cabinet?
1, plastic tableware disinfection. Tableware that can't withstand high temperature, such as plastic, can't be placed in the high-temperature disinfection cabinet below, but in the ozone disinfection low-temperature disinfection cabinet above to avoid damaging the tableware.
2. Colored porcelain utensils can't be put in. Colored porcelain tableware put into the boss's disinfection cabinet will release harmful substances and endanger human health. Because ceramic bowls, plates, pots, basins, etc. When glazing, their enamels and pigments contain toxic heavy metals such as lead and cadmium. Usually, these substances are relatively stable, but they are easy to overflow when they encounter high temperatures. In the working state of the disinfection cabinet, the internal temperature can be as high as 200℃.
Often putting food in these sterilized colored porcelain will pollute food and endanger health. 3. Other precautions. Pay attention to whether the ozone generator works normally when using the boss ozone disinfection cabinet. If you can't hear the squeak of high-voltage discharge or see the blue light of discharge, it means that the ozone generator may be out of order and should be repaired in time. The disinfection cabinet should be placed in a dry and ventilated place, not less than 30CM away from the wall. Don't open the door unless necessary during disinfection, so as not to affect the effect. After disinfection, it will be better to take it ten minutes later. Open the cupboard door, and a small amount of ozone odor overflows. This concentration is harmless to human health. Please rest assured. Wipe the water in the water collecting tank at the lower end of the cabinet regularly.
? How to maintain the disinfection cabinet?
1. The disinfection cabinet must be installed or placed in a well-ventilated place.
2. The disinfection cabinet is only applicable to the disinfection and cleaning of tableware, and non-tableware cannot be put into the disinfection cabinet.
3. When using, do not put articles that are not resistant to high temperature (such as plastic tableware, glass products, wooden or painted tableware) and articles that are not resistant to oxidation into the disinfection cabinet. Otherwise, the tableware will be deformed or damaged.
4. Before opening the disinfection cabinet, the cabinet door must be locked. If the door is not closed tightly, it will not only fail to play its due role in disinfection and cleaning, but also waste resources and damage the machine.
5. After the disinfection and cleaning work is completed, a lot of steam will be generated in the cabinet. In order to prolong the service life of the disinfection cabinet, please open the door for ventilation after the disinfection cabinet program is executed for 20 minutes to eliminate the steam in the cabinet, and wipe the residual steam in the cabinet cavity with a clean rag to prevent the cabinet from rusting and mildew.
6. Ensure that the disinfection cabinet is electrified once a day, which can not only ensure the hygiene of the disinfection cabinet, but also prolong its service life. Turn it off when not in use.
