The microwave dryer has the function of thawing, sterilizing, curing, and drying. The color and nutritional content of the material remain unchanged. The drying time is fast, continuous and automatic work.
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 polarityorientation 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.
During the equipment is working the microwave generator produce the microwave. The materials enter into the heating chamber by conveyor.At this time,moisture and bacteria inside the material inside the material evaporate under the action of microwave energy to achieve unfreeze sterilization ripening fixing drying purpose.
