Tunnel type microwave dryer and sterilizing machine for herb

Microwave is a sort of electromagnetic wave which frequency is 300GHZ. The water molecule in medium material is polar molecule, under the effect of the repaid change of electromagnetic field, it is polarity orientation will alter with the changes of external electric field with high-speed, causing the movements and friction of molecule, so that the microwave field energy can be converted to heat energy in medium to rise the temperature of materials, accomplishing heating, puffing and a series of physical processes and so microwave is achieved.

Applicable for pepper,aniseed,chili and other spics powder, granules, various spices extract and various food additives drying and sterilization.
