major function

Rely on to hundreds of millions of times per second speed of periodic variation of microwave penetration material, the polar molecular interactions with the material, material in the polarity of the (such as water molecules) after absorbing microwave, change the original molecular structure also at the same speed as electric polar motion, causing Peter here frequent collisions that produce large amount of friction heat, so that material in each part at the same instant get heat and temperature, have been produced thermalization, puffing and water evaporation, so as to achieve the purpose of heating drying and sterilizing.
