(2) steam disinfection: put the clean dishes into a steam cabinet or box, so that the temperature rises to 100 ℃, disinfection for 5-10 minutes;
(3) oven disinfection: such as infrared sterilizer, the temperature is generally around 120 ℃, disinfection 15-20 minutes.
Most of the bacteria that can generally cause intestinal diseases have to be 100 ℃ high-temperature effect of 1-3 minutes or 80 ℃ heating for 10 minutes to die. Therefore, boiling water before eating a bowl, due to insufficient action temperature and action time, can only kill a very small number of microorganisms, and can not guarantee to kill the majority of pathogenic microorganisms. To achieve the effect, boiling, circulating steam or using infrared sterilization dish cabinet are optional methods. If you use boiling, be sure to cook for a while longer, with infrared disinfection dishwasher generally to maintain 15-30 minutes.
