Has specific to electric field the features such as cycle of oscillation is short, penetration capacity is strong, can produce specific effect with matter interaction.Tradition
Drying means, such as flame, hot wind, steam, electric heating are external heat drying, after surface of material absorbs heat, are passed through heat
It leads, inside heat leak to material, heat up drying immediately, and microwave drying is then entirely different, it is a kind of internal side heated
Method.Wet stock is in cycle of oscillation extremely short microwave high-frequency electric field, and internal hydrone can occur polarization and along microwave
The direction proper alignment of electric field then changes with the interaction in high-frequency alternating field direction rapidly and is rotated, and generates violent touch
It hits and rubs (each second up to more than one hundred million time), as a result a part of microwave energy is molecular motion energy, and the table in the form of heat
Reveal and, so that the temperature of water is increased and is left material, so that material be made to obtain drying, that is to say, that microwave enters material and quilt
After absorption, energy is in material dielectric internal conversion at thermal energy.Therefore, microwave drying be using electromagnetic wave as heating source,
A kind of drying mode of the dried material sheet as heater.China's microwave drying technology has been used for food industry, materialized
Work, medical industry, exploitation of mineral resources industry, ceramic industry, lab analysis, the processing of wet natural rubber etc..
Currently, the drying of granular material (such as iron powder) still uses manual type to operate, and the heat source heated is heat
The problems such as air or high-temperature flue gas etc., it is low that accordingly, there exist drying efficiencies, and worker operation intensity is big.
