Snack Industry Tunnel Microwave Drying and Sterilization Machine

Working principle for microwave drying machine:
Microwaves are electromagnetic waves at a frequency of 300 MHz to 300 GHz. The material in the heating medium in the molecules of water is a polar molecule. It in the rapidly changing under high frequency magnetic field, its polarity orientation will be with the change of external electric field changes, resulting in molecular motion and friction between the effect, this field of the microwave field can transformed into thermal energy within the medium, the temperature of the material increased, heating and puffing a series of physical and chemical processes, so as to achieve the purpose of microwave heating and drying.

Advantages

1.  Rapid drying

Microwave heating does not need the progress of heat conduction, wich make the material itself become a heating  unit.

2.  Symmetrical heating

Because of no restrictions on the shape of the material, the materials is heated even, and theres is no adjust outside  or unheated inside.

3.  Energy saving and efficient

The microwave drying can save one third energy of the far-infrared drying

4.  Mildew proofing/sterilizing/keeping fresh

Microwave drying with thermal and biological effects can sterilize and resist rot under lower temperature.

5.  Advanced craftwork and easy control

With the use of graphic operation terminal and PlC, you can realize programmable auto-control of heating progress.

6.  Safety and innocuity.

There is no harmful radioactivity or harmful gas, or waste heat or dust pollution, so neither could microwave heating contaminate food nor pollute the environment.
