Multi-Functional High Quality Microwave Vacuum Drying Dehydrator for Food Processing

Product Description

The microwave heating principle
Microwave frequency is electromagnetic waves of 300 MHz -300 GHz. The water in medium materials heated is polar molecules, 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 energy can be converted to heat energy in medium to rise the temperature of materials.Then materials heated go to produce heat, puffing and a series of physical and chemical processes, and so, microwave heating achieved.

Advantages :
1. High energy conversion efficiency and fast heating speed. Microwave ovens do not heat themselves, but microwave energy can penetrate the material, causing polar molecules in the material to rub against each other and generate heat. So there is no energy loss.
2. The expansion effect is obvious. The rapid heating effect of the microwave causes the water molecules in the material to evaporate rapidly to achieve the purpose of expansion.
