The device uses the microwave heating principle, the materialin the process of heating dehydration, softening, volatile smell of grass, the activity of the purified enzyme,appearance, colour and lustre is good. Equipment design is reasonable, compact structure, reliable performance, simple operation,convenient maintenance, following are main characters of it .

Working principle
Microwave drying is such a drying method that material absorbs microwave energy which can be converted into heat, so that the material has an overall heating both internally and externally at the same time and it is completely different from other conventional drying methods.
Conventional drying method is based on the principle of heat conduction, convection and radiation which transfer heat from external to internal, inevitably there is a temperature gradient in the material, therefore, heating is uneven and there may result in local overheating.
Microwave drying technology is different from the conventional drying method, which is by means of high frequency reciprocating motion of the dipolar molecule of the material, resulting in internal friction heat which heats material, without any heat transfer process, and the material is heated both internally and externally at the same time with high speed drying and uniform drying result, and energy consumption is far less than traditional heating.

Microwave drying, sterilization, heating, preservation, extraction, synthesis, puffing, thawing and sintering equipment have been widely used in leather, wood, color printing, food, spices, chemicals, pharmaceuticals, tobacco, building materials, ceramics, paper, rubber and medical fields.
Characteristic of fast speed, energy saving, high production efficiency, uniform drying, clean production, easy to achieve automatic control and improve product quality and so on.
