Clinical Waste Disinfection Treatment Unit Model MMDU-17


It’s a sterilizer that uses the dual effects of microwave and high-pressure steam to disinfect medical waste.

Treatment capacity appr. 2kg/hr, based on an average density of medical waste at 0.1kg/l ~0.15kg/l.

Technical Principle:

Microwave disinfection equipment for medical waste is a device that uses the dual effects of microwave and high-pressure steam to disinfect medical waste. The equipment first introduces high-pressure saturated steam into the high-pressure disinfection chamber of medical waste, while starting a microwave generator. 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 ℃ or above, it is kept for another 5 minutes to complete the disinfection.
