Food microwave equipment

Microwaves are electromagnetic waves at frequencies from 300 MHz to 300000 trillion Hz. The material in the heating medium in the molecule of water is a polar molecule, it in the rapidly changing under high frequency magnetic field, its polarity orientation will be with the change of external electric field changes, resulting in molecular motion and friction between the effect. This field of the microwave field can transformed into thermal energy within the medium, the temperature of the material increased, heating and puffing a series of physical and chemical processes, so as to achieve the purpose of microwave heating and drying.
