Microwave heating is an internal heating method, electromagnetic energy molecules act directly on the medium is converted into heat, and transmission properties so that the material inside and outside the media at the same time heat, no heat conduction, and the lack of internal heat dissipation, resulting in an internal temperature higher than external temperature gradient distribution, forming the drive internal moisture to penetrate the surface of the vapor pressure difference, accelerate the rate of evaporation of moisture migration. Microwave heating furnace Especially for moisture content below 30% of the food, the speed can be hundreds of times shortened, in a short time to achieve uniform drying.
