Efficiency advantage When do freeze-drying operation to materials, we need to supplement sublimation heat and the traditional supplemental methods are mainly three kinds: electric heating, diesel heating, alcohol heating; however, in the vacuum state, there is almost no convection and …

Microwave’s wavelength is from 1mm to 1m and its frequency is from300MHZ to 300GHZ. It is similar to light.It is the selectivity of the interaction between the microwave and the substance.Its quantum level is low.

Microwave heating principle Absorbing microwave energy is the interaction result that occurs between polar molecules in material and microwave electromagnetic field. Under the action of external alternating electromagnetic field， polar molecules appear polarization phenomenon and change their alternating orientation following …
