Complaint
Liying company's product, MDU series of medical waste microwave disinfection equipment adopts a fully automatic processing system of hydraulic lifting, material shredding, microwave disinfection, and spiral discharge, which is short in time and efficient, and can effectively save energy. The treatment process does not produce dioxin and odor gas, and there is no wastewater discharge. The killing rate of spores of Bacillus subtilis black variety is not less than 99.99%. All sterilization effect monitoring, exhaust gas monitoring, microwave leakage monitoring, etc. are qualified.
This series of equipment is divided into two categories: skid-mounted fixed equipment and mobile microwave disinfection vehicle, according to different models and specifications, it can adapt to the requirements of various types of medical waste centralized disposal centers and emergency disposal, in situ disposal. The whole set of equipment only needs electric power drive. 1 person can operate and the daily processing capacity of 0.1 tons -10 tons. It has the advantages of low energy consumption, small footprint, low noise, cleanliness, environmental protection and can be turned off and on at any time according to the amount of medical waste, which greatly reduces the operating costs. The mobile medical waste disinfection vehicle can be parked and operated, with its own generator, water tank and water purification equipment, providing medical waste on-site disposal services to and from many areas,safe and stable.

Processing
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 ≥95ºC, duration over 45minutes. 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.
Working Principles
What did the Microwave Disinfection Unit (MDU) do to bacterias?
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.

Contribution to society
Mr. Zhang said in an interview that Liying Company's medical waste microwave disinfection equipment was developed in 2014. At the time of the epidemic outbreak in Wuhan, our microwave equipment has been more mature after several optimization and upgrading, and the sales situation is very good. In the face of the epidemic, the country has a need and we have a responsibility. Therefore, Liying decided to donate disinfection equipment to support Wuhan and dispatch multiple batches of staff to the front line of the epidemic during the subsequent epidemic period.
