Tunnel type continuous microwave sterilization equipment can be used to sterilize for material processing. The microwave sterilization method has lots of advantages, such as rapid sterilization, complete sterilization, and no adverse effect on the material. Microwave sterilization method adopts both thermal effect and non-thermal effect of electromagnetic field, to penetrate and disrupt the cell structure and the genetic material of all kinds of bacteria and enzymes within very short time to kill the bacteria quickly.
