This device can handle medical waste such as infections, injuries, and pathological materials, and provides harmless disposal of medical waste. The integrated design ensures low energy consumption for the entire system, automated operation, simplicity in use, and the ability to process medical waste anytime, anywhere. Fixed or mobile configurations can be customized according to needs, offering flexibility and convenience. The microwave disinfection treatment system is an integrated unit composed of at least 10 components, including an automatic feeding unit, sealed chamber unit, multifunctional 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 results from the combined effects of microwave thermal and biological actions, enabling direct interaction with bacteria for rapid sterilization. 1. Thermal effect of microwave energy: Under a certain intensity of the microwave field, bacteria absorb microwave energy due to molecular polarization, leading to the denaturation of proteins and physiologically 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 physiologically active substances within microorganisms, resulting in loss of vitality or death. This non-thermal effect plays a unique role in sterilization that conventional physical sterilization methods do not achieve.
