The principle of microwave drying



Microwave frequency is electromagnetic waves of 300 MHz -300 GHz. The water in medium materials heated is polar molecules, under the effect of the rapid change of electromagnetic field, its polarity orientation will alter with the changes of the external electric field with the high-speed, causing the movement and friction of molecule. So that the microwave field energy can be converted to heat energy in medium to rise the temperature of materials.Then materials heated go to produce heat, puffing and a series of physical and chemical processes, and so, microwave heating achieved.

Applications of industrial microwave drying machine
Industrial microwave drying machine can be applied to food, spices, food, agricultural products, insects, wood, chemical powder, ceramic products, drying or cure.
Features
Microwave drying is the use of material in the polar molecules (water molecule) do billions of times per second in die high frequency electromagnetic field of the friction collision and generate heat, so as to achieve the purpose of heating drying.
Without external heat source, by microwave effects, the materials to be heating element itself, without thermal conductivity, high efficiency and energy saving, uniform drying.
Without preheating and drying process, a few minutes to reach the required heating temperature, without loss of thermal inertia.
Fast drying, material from the tunnel into the equipment to the finish drying only a few minutes.
Use clean energy – electricity, there is no waste emissions, environmental security.
