Purpose
It is mainly applicable to fast drying for various finished/semi-finished products of Chinese/western medicines, Chinese medicinal materials, health care products and biological products as well as drying, sterilization, mould prevention for food, chemicals, agricultural byproducts, woods and paper products etc.

Principle
Drying principle: Under the action of continuous fast-changing high frequency electromagnetic field, the polarity orientation of materials will change with external electric field when passing specially-made conveying belt, resulting in movement and mutual friction effect of molecules inside materials. At this time, microwave magnetic field energy is changed into thermal energy inside media to increase the temperature of materials. Continuous magnetic field energy is transformed into thermal energy which can dry materials quickly at low temperature.
Sterilizing principle: microwave sterilizing utilizes thermal effect and non-thermal effect to jointly kill microorganisms.
1.Thermal effect of microwave energy: Under the action of microwave magnetic field with certain intensity, the insects and thallus in food will suck microwave energy to increase temperature due to molecular polarity changes in their body so as to cause protein denaturation and lose biological activity. Microwave thermal effect mainly has the function of fast heating sterilization.
2.Non-thermal effect of microwave energy: High frequency electric field can change membrane potential, polar molecule structure, and change microbial body protein and physiological active substance, making microbial body dead after losing vitality.

Features
1.Segmental stepless adjustable microwave power ensures evenness of drying effect and achieves the aim of saving energy during operation.
2.Self-cooled industrial strength 1500W transformer is designed for continuous operation, with strong and stable power.
3.Assembly technology of direct water-cooled industrial strength 1050W magnetron is grasped to realize long continuous operation.
4.Adopt large air flow centrifugal fan, adjust dehumidifying speed of air flow regulating device according to different materials.
5.Infrared temperature measurement and control system can accurately measure the temperature of materials in good time, ensure accuracy of temperature control, and facilitate improving product quality.
6. Material feeding/discharge positioning device makes material tray stop at furnace chamber door to facilitate operation, reduce labor intensity of the operator. 
7.Rectangle microwave guiding assembly unit is developed to have small wave-guide stationary wave, which can better match with magnetron to ensure its high output efficiency.
8.Microwave operating time can be calculated automatically. This dryer can calculate microwave power, drying time after several basic parameters of materials are input. Materials can be discharged when operation time is over. 
9.Automatic balancing technology ensures constant balanced state for liquid materials, which solves the technical problems of material inclining, material tray collision and overturning.
10.Install electronic monitoring device and vacuum sight glass hole (dual structure) to view and monitor material state in real time, grasp its characteristics and drying degree and better control operation.
11.The monitoring of cooling water flow rate and temperature can completely avoid insufficient flow rate resulted from outlet pipe blockage, magnetron damage caused by too high water temperature.
