First, it cannot be sterilized. For example, if the common hepatitis B virus is not heated to a high temperature above 120℃ in the disinfection cabinet, it can't be killed by traditional boiled water.
Second, the secondary pollution is serious. At present, due to the material itself, coupled with the low level of manufacturing technology, some products have poor sealing performance, and the incompletely closed cupboard door can not stop the patronage of dust, ants, cockroaches and flies, which is easy to cause secondary pollution of tableware.
Third, it is easy to get wet and easy to have hairy bacteria. Wooden bowl racks are prone to moisture because they are often wet, especially in the rainy season in the south, which often has long hair and breeds a lot of bacteria. What happened under our noses probably won't be noticed. If the tableware is not cleaned and disinfected before use, the result will be terrible. Disinfection cabinet can solve this problem, so as to avoid the disease from entering the mouth.
