Can ultraviolet rays in the disinfection cabinet kill Helicobacter pylori on tableware?

yes. Generally, the high-temperature disinfection of tableware disinfection cabinet adopts heating temperature greater than 111℃ and lasts for more than 1.5 min, so as to denature the protein tissue of microorganisms including bacteria and viruses and achieve the purpose of killing bacteria and viruses.

the ultraviolet lamp used for disinfection and sterilization should be a high ozone ultraviolet lamp, and the wavelength range of ultraviolet light is 211 ~ 275 nm, among which the band with the strongest sterilization effect is 251 ~ 271 nm. When the voltage of the ultraviolet lamp used for disinfection is 221V, the intensity of ultraviolet radiation at 253.7nm should be no less than 71μWcm2.

The ultraviolet radiation energy is low, and the penetration is weak, which can only kill the microorganisms directly irradiated. Therefore, the disinfection site must be fully exposed to ultraviolet light during disinfection. The ultraviolet lamp produces ozone at the same time, which also plays a bactericidal role.

Precautions for the use of the disinfection cabinet:

1. Put the washed tableware and other things into the basket in a vertical way, which is conducive to draining water and leaves gaps to avoid stacking.

2. The tableware disinfection cabinet should be placed horizontally, with no sundries around, dry and ventilated, and the distance from the wall should not be less than 31CM.

3. After disinfection, the cabinet is still at a high temperature, which is easy to burn the skin. Generally, it takes 11-21 minutes to open the cabinet to take things. If tableware is not used temporarily, it is best not to open the cabinet door, so that the disinfection effect can last for several days.

4. Do not open the door unless it is necessary during disinfection, so as not to affect the effect.

5. Consumers should not treat the disinfection cabinet as a safe when using it. Because the disinfection cabinet is in a sealed state, if the tableware stored in the cabinet is not thoroughly disinfected, the disinfection cabinet has become a hotbed of bacteria. Therefore, from the perspective of safety and hygiene, it is better to open the disinfection cabinet once a day.

6. Do not open the cupboard door unless necessary during disinfection, which will not only affect the disinfection effect, but also increase the power consumption. If it is a high-temperature disinfection cabinet, after disinfection, the temperature in the cabinet is still high, and it usually takes 11 ~ 21 minutes before opening the cabinet to take things. Turn off the power supply or unplug the power supply in time after each disinfection.
