MDU-3B Infectious Waste Microwave Treatment Units for Medical Waste
0 likes
China [CN] MDU-type medical waste microwave disinfection equipment is used for the harmless disposal of medical waste. The scope of disposal is medical waste that is classified as infectious, traumatic, and pathological waste (except for human limbs and organs). It can also be used in epidemics When dealing with sick and dead poultry.
MDU-3B
Microwave disinfection unit for medical waste Model MDU-3B
MDU-3B is an integration system including feeding, shredding, disinfection, discharging, and exhaust dedusting systems.
180kg/h treatment capacity, or 1800l/h, based on an average density of medical waste at 0.1kg/l ~0.15kg/l.
It can service well to large scale hospitals, or any other healthcare centers, whose medical waste quantity would be 1.5 tons per day (±10%).
PROCESS
The infectious material is temporarily held in a waste container(s) which in turn, are emptied into an 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 microwave of 2450MHz (±50MHz), temperature ≥95℃, with 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 bacterium?
How is the Microwave Disinfection Unit (MDU) disinfecting by microwave?
Microwave disinfection is the result of microwave thermal effect and biological effect, which can make microwave energy and bacteria directly interact, rapid sterilization.
The thermal effect of microwave energy: Under 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, loss of biological activity. The thermal effect of microwave 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
Achieve effects that conventional physical sterilization does not have
