manufacturers large industrial microwaves

Microwave drying equipment is the principle of the frequency of 300 MHz to 300,000 MHz electromagnetic waves. The water molecule in the heated medium material is a polar molecule. Under the action of fast changing high frequency electromagnetic field, the polarity orientation will change with the change of the external field, which results in the movement and friction effect of the molecule. The field of the microwave field can be converted into the heat energy in the medium, so that the material temperature rises, and a series of physicochemical processes such as heating and puffing are produced, so as to achieve the microwave heating drying.
