Infrared ray sounds very advanced, but generally speaking, it inactivates germs through high temperature, which is what we often call physical disinfection.
There are two other ways: ultraviolet and ozone sterilization are relatively mild, that is, by destroying/oxidizing the genetic material and survival-related tissue structure of bacteria, the purpose of disinfection is finally achieved.
In fact, all three methods have good sterilization effect, which is not as different as what is rumored by the outside world. After all, sterilization is only standard. However, the disadvantage of infrared ray, that is, high-temperature disinfection, is obvious: if the temperature is too high, certain materials, such as plastic and wood, will definitely not be disinfected, and once the tableware is disinfected, it is estimated that it will be damaged and unusable. Moreover, for some thermotolerant bacteria, the effect of temperature on them is very limited, and some thermotolerant bacteria may remain on the tableware after disinfection.
Generally, ultraviolet rays and ozone are combined in a disinfection cabinet, just like a combination boxing. Both of them have no requirement on temperature, and the disinfection materials are more comprehensive and have strong ultraviolet sterilization ability. Ozone can make up for the place where ultraviolet rays can't reach, and the general sterilization effect can reach 99.9% by combining the two, but there may be some ozone smell after disinfection. The residual ozone of regular products reaches the standard and is harmless to human body. The smell problem still varies from person to person. If you compare,
If you still don't know, Baidu search is too disinfection cabinet, you will understand it all ~
