What are the characteristics of a Dielectric dryer?

Answer:

Because the material water within high specific surface, so the material inside more energy than the surface temperature, temperature of material, so that the temperature gradient and moisture diffusion in the same direction, can accelerate the vaporization of water, shorten the drying time
Dielectric heating is used in food and light industry because of its high energy consumption
This dryer is especially suitable for drying in the process of easy crusts and internal moisture is difficult to do the material
The higher the moisture content in the material, the more heat it gets
The dry material is placed in a high frequency electric field and heated by the alternating action of the high-frequency electric field
