This device is capable of handling medical waste such as infections, injuries, and pathological materials, and carries out harmless disposal of medical waste. With an integrated design, the complete system features low energy consumption, automated operation, simple handling, and the ability to process medical waste anytime and anywhere. Fixed or mobile configurations can be customized according to needs, offering convenience and flexibility. The microwave disinfection treatment system is an integrated unit composed of at least 10 components, including an automatic feeding unit, sealed chamber unit, multi-function sealed crushing unit, negative pressure extraction unit, microwave disinfection and sterilization chamber unit, microwave generator unit, steam heating system, discharge unit, automatic control unit, exhaust gas treatment unit, and an alarm system. Microwave sterilization is the result of the combined action of microwave thermal effects and biological effects, allowing microwaves to interact directly with bacteria for rapid sterilization. 1. Thermal effect of microwave energy: Under the influence of a certain intensity microwave field, bacteria absorb microwave energy due to molecular polarization, leading to the denaturation of proteins and physiological active substances, thereby losing their biological activity. The thermal effect of microwaves primarily facilitates rapid heating and sterilization. 2. Non-thermal effect of microwave energy: High-frequency electric fields alter the structure of polarized molecules, causing mutations in proteins and physiological active substances within microorganisms, resulting in loss of vitality or death. In sterilization, conventional physical sterilization methods do not exhibit such specific effects.
