Disinfection cabinet refers to tools for drying, sterilizing, disinfecting, warming and dehumidifying food utensils, tableware, towels, clothing, beauty salons, medical equipment and other items through ultraviolet, far infrared, high temperature, ozone, etc. The appearance is generally a cabinet Box-shaped, most of the cabinet body is made of stainless steel, and the panel is made of tempered glass or stainless steel.

Disinfection cabinet principle

1. The principle of ultraviolet disinfection cabinet

The sterilization principle of the ultraviolet disinfection cabinet is to irradiate bacteria, viruses and other microorganisms by ultraviolet rays, so as to damage the DNA structure in the body, kill bacteria or lose the ability to reproduce. DNA has the strongest absorption of ultraviolet rays with a wavelength of 253.7nm. The sterilization effect of ultraviolet rays is related to the irradiation intensity and the total irradiation amount, and the kill rate is generally ≥ 99%.

2. Principle of high temperature disinfection cabinet

High temperature sterilization is achieved by heating the temperature to 100 ℃ and maintaining it for more than 15 minutes to achieve the purpose of sterilization. This high temperature sterilization mainly includes microbial organisms including bacteria and viruses. The high-temperature sterilization cabinet generally adopts the far-infrared heating method. The electric heating element heats the air or generates radiant heat. After the appliance is subjected to high temperature for a period of time, the surface of the bacteria, viruses and other microbial organism protein tissues are deformed and thus killed.
