PROCESS
The infectious material is temporarily held in a waste container(s) which in turn, are emptied into a pre-storage hopper via a charging system which is located at the front of the MDU, The infectious waste is fed to the shredding system by a feed arm where it is shredded. The shredded material is conveyed through a microwave section and temperature holding section, respectively for disinfection, with a microwave of 2450MHz (±50MHz), temperature ≥95℃, for over 45 minutes. The disinfected and unrecognizable (sharps) waste is then discharged into large waste containers (or compaction units) by the discharging screw conveyor. From there the material can be transported to a local municipal landfill for disposal or to a refuse recycling plant.

What did the Microwave Disinfection Unit (MDU) do to bacteria?
How is the Microwave Disinfection Unit (MDU) disinfected by microwave?

Microwave disinfection is the result of microwave thermal effects and biological effects, which can make microwave energy and bacteria directly interact with rapid sterilization.

The thermal effect of microwave energy: Under a certain intensity microwave field, the bacteria will be due to the absorption of polarized molecules can increase the temperature of microwave, so that the protein deformation, and loss of biological activity. The thermal effect of microwaves mainly plays the role of rapid temperature sterilization.

Non-thermal effects of microwave energy: High-frequency electric fields change the polarized molecular structure, resulting in the loss of vitality or death of proteins and physiologically active substances in the microbes, and the special effects of conventional physical sterilization in the sterilization
