Medical Waste High Temperature Microwave Disinfection Unit, model MMDU-21P
It’s a device that uses the dual effects of microwave and high-pressure steam to disinfect medical waste.
Treatment capacity appr. 10kg/hr, based on an average density of medical waste at 0.1kg/l ~0.15kg/l.
Technical Principle
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.

Process Flow
Feeding:
Put the bags with medical waste into the material box in the disinfection chamber, and after loading through the PLC control panel, the material box automatically resets and seals with the disinfection chamber, and then closes the outer double doors.
Disinfection:
Start disinfection through PLC control panel operation, and enter the microwave disinfection stage. After the pressure reaches above 0.33MPa and the temperature reaches above 135 degrees Celsius, keep the disinfection for 5 minutes and then complete the disinfection. The system releases pressure and cools down automatically. After reaching the set temperature and no-pressure state, the outer double door can be opened after being prompted, and the disinfection chamber is automatically moved out.
Shredding:
Take out the material box, pour the sterilized waste into the shredding chamber, and close the chamber flap. At this point, the next cycle of medical waste can be put into the material box of the disinfection chamber, and the outer double doors then closed.
Discharging:
The shredding is started through the PLC control panel, the shredded and unrecognizable waste pieces automatically falls into a new non-infected garbage collector to complete the treatment.
At the same time, the microwave disinfection chamber will carry out the next cycle of disinfection of medical waste simultaneously.
