The principle of ultraviolet disinfection cabinet: through ultraviolet irradiation, the DNA structure of microorganisms is destroyed and changed, so that bacteria die or cannot reproduce.
The principle of light wave disinfection cabinet: light wave irradiation produces high temperature, and the protein of bacteria is heated to stop its activity and finally die. The lamp tube is electrified and emits light to generate radiant heat, so that the surface of tableware in the furnace cavity reaches a certain temperature, thereby killing bacteria and viruses on its surface. Therefore, the light wave disinfection cabinet is not suitable for tableware that is not resistant to high temperature, and the surface of tableware that cannot be irradiated has low temperature, poor thermal uniformity and poor sterilization effect.
Principle of microwave disinfection cabinet: microwave makes the water molecules carried by bacterial virus vibrate, friction generates heat, and the bacterial virus dies after the temperature rises. Microwave can't penetrate metal, so microwave disinfection cabinet is not suitable for disinfection of metal tableware.
