It uses the thermal effect of microwave to heat the high-pressure disinfection chamber to maintain temperature and prevent steam condensation. It is sterilized by the sensitivity of bacteria to temperature. In addition, microwave has a non-thermal effect, Non thermal effect refers to other microbial killing effects besides thermal effect, which is a unique effect of microwave sterilization. The heating and warming process of the equipment is also a disinfection process. After the disinfection room reaches 135 ºC or above, it is kept for another 5 minutes to complete the disinfection.
