The advantages of microwave dryer compared with traditional one



Traditional heating, such as flame, hot air, electric, steam drying are using the principle of thermal conductivity, heated from external importing to internal, so making the center of the object temperature rises gradually which called the external heating. To make the central portion reaches a desired temperature requires ceramic a certain time for drying equipment. The objects of the poor thermal conductivity require longer time. These conventional drying methods takes a long time, power consumption, and less uniform heating, flip up and down, the labor intensity, and microwave drying characteristics. Otherwise, the microwave dryer can penetrate inside and outside while being heated the interior of the object with the frequency 2450MHZ, 24 per second 150 million times shock, friction between the molecules generates heat.

1, dry quickly
Microwave dryer is completely different with traditional drying methods. It make the dried material itself heated, no heat conduction process. Thus, despite the poor thermal conductivity of the material, microwave dryer can also be achieved within the drying temperature a very short time.

2, uniform drying
Wherever the object is, the shape of the various parts of the microwave drying can penetrate electromagnetic waves to generate heat uniform. So its good dry uniformity does not occur phenomenon of outside is burned but the internal is soggy.

3, energy-efficient
Easily absorb microwaves and fever due to contained water-containing substances, in addition to a small amount of transmission loss, almost no other loss. Therefore, thermal efficiency saves more than 1/3 than infrared drying energy.

4, mildew, sterilization, and preservation
Microwave dryer have thermal effects and biological effects, can be sterilization and mildew the temperature in the lower temperature. Fast drying time max preservation of the vitamin activity and food materials, the original color and nutrients.

5, state-of-the-art technology
Control microwave power can be realized immediately dried and terminate. Application man-machine interface and PLC programmable automation control the drying process and dry process specifications.

6 safe
The microwave energy is controlled in the metal drying chamber and the waveguide, so there is very little leakage of microwave radiation hazards and harmful gas emissions, and does not generate waste heat and dust pollution, neither contaminate food, do not pollute the environment.
