1. The drying time is short, and the flavor of the product is strong;
2. The drying temperature is low and uniform, and the color of the product is bright;
3. Selective heating. Because water molecules absorb microwave well, the part with high water content will absorb more microwave power than the part with low water content. This is the characteristic of selective heating, which can be used to achieve uniform heating and uniform drying;
4. The moisture direction of drying and dehydration is from inside to outside. Therefore, microwave drying has a puffing effect, which is very helpful for subsequent crushing;
5. Microwave acts on materials directly, so there is no additional heat loss.
