consumers may encounter some problems when using the sterilizer, but how much do you know about the principle of the sterilizer? How much do you know about the correct use of disinfection cabinets? Don't worry, let's talk about the principle of disinfection cabinet and how to use it!
Principle of disinfection cabinet:
① Principle of disinfection cabinet-ozone disinfection cabinet:
Actually, ozone disinfection cabinet uses the strong oxidation of ozone for disinfection. Ozone is a bluish explosive gas at room temperature, which has a special odor. It is one of the strongest oxidants known and a spectral bactericide. However, ozone leakage will do harm to our health, and the allowable valve limit in the air of the job site is 1.2mg/m3. Therefore, the ozone disinfection cabinet should keep the concentration of ozone in the cabinet under the condition of ensuring that ozone does not leak, so as to ensure the disinfection effect.
② disinfection cabinet principle-ozone plus ultraviolet tableware disinfection cabinet:
About ozone plus ultraviolet tableware disinfection cabinet, ultraviolet and ozone are used as disinfection methods. The ultraviolet lamp used for disinfection and sterilization should be a high ozone ultraviolet lamp. The wavelength range of ultraviolet light is 211 ~ 275 nm, and the band with the strongest bactericidal effect is 251 ~ 271 nm. Ultraviolet radiation has low energy and weak penetration, and can only kill microorganisms directly exposed. Therefore, the disinfection site must be fully exposed to ultraviolet rays during disinfection. The ultraviolet lamp produces ozone at the same time, which also plays a bactericidal role.
③ disinfection cabinet principle-electrothermal disinfection cabinet:
For electrothermal disinfection cabinet, high temperature is used to play a sterilization role. High temperature is lethal to bacteria. Protein in bacteria is denatured and solidified due to heat, and its activity disappears, resulting in metabolic disorder and death. The disinfection temperature of the electrothermal disinfection cabinet should be ≥111℃ and the disinfection time should be ≥15 minutes.
How to use the disinfection cabinet:
1. Wash and drain the tableware before putting it into the disinfection cupboard for disinfection, which can shorten the disinfection time and reduce the power consumption.
2. Tableware that can't withstand high temperature, such as plastic, should not be put in the lower high-temperature disinfection cabinet, but should be put in the upper ozone disinfection low-temperature disinfection cabinet to avoid damaging the tableware.
3. The colored porcelain ware will release harmful substances when put into the disinfection cabinet, which is harmful to human health. Because ceramic bowls, plates, jars, pots, etc., when glazed, their enamel and pigments all 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 211℃. Often placing food in these sterilized colored porcelain will pollute food and endanger health.
4. Tableware such as bowls, plates and cups 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. Pay attention to whether the ozone generator works normally when using the 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.
6. The disinfection cabinet should be placed in a dry and ventilated place, not less than 31CM away from the wall.
7. Don't open the door unless it is necessary during disinfection, so as not to affect the effect
8. After disinfection, it will be better if you take it again after ten minutes. When opening the cupboard door, there is a small amount of ozone smell overflowing. This concentration is harmless to human health. Please rest assured.
The above is the principle of the disinfection cabinet and the usage of the disinfection cabinet, which we summarized. I hope it will help you to understand the knowledge of the disinfection cabinet.
