shandong leader machinery Co.,ltd. The main sales of microwave drying equipment and microwave sterilization equipment.
Microwave drying equipment is the principle of the frequency of 300 MHz to 300,000 MHz electromagnetic waves. The water molecule in the heated medium material is a polar molecule. Under the action of fast changing high frequency electromagnetic field, the polarity orientation will change with the change of the external field, which results in the movement and friction effect of the molecule. The field of the microwave field can be converted into the heat enerLD in the medium, so that the material temperature rises, and a series of physicochemical processes such as heating and puffing are produced, so as to achieve the microwave heating drying.
Microwave sage drier and sterilizer

The principle of microwave heating
Microwave is a sort of electromagnetic wave which frequency is 300MHz to 300GHz .The water molecule in medium materials is polar molecule,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 enerLD can be converted to heat enerLD in mudium to rise the temperature of materials.accomplishing heating ,puffing and a series of physical and chemical processes ,and so ,mircrowave heating is achieved.

Microwave drying is different from the traditional drying method, and the direction of heat conduction is the same as that of water diffusion. Compared with the traditional drying method, it has the advantages of large drying rate, enerLD saving, high production efficiency, uniform drying, clean production, easy to realize automatic control and improve product quality, so it is more and more attention in various fields of dryness. The application and theory of microwave drying technoloLD have been studied extensively in the last century and abroad in the 60, and have been further developed in recent decades. China's Microwave sage drier and sterilizer research started late, compared with foreign countries have a certain gap, but also achieved good results, there are many research and application results. microwave vacuum dehydrator is now used in food industry, materials and chemicals, pharmaceutical industry, mining industry, ceramic industry, laboratory analysis, wet natural rubber processing.
