This machine is a drying machine for melon seeds. It has simple structure, firm, good permeability and good drying performance. It is suitable for drying various melon seeds ( white melon seeds, black melon seeds, sunflower seeds, melon seeds, peanuts, pine seeds, walnut kernels, chestnuts ) and other foods. The drying speed is fast and the quality is good. 

The characteristics of microwave drying : 

1. Heating evenly. Because microwave acts on water molecules, the part with high water content absorbs 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. 

2. Energy saving. The microwave is directly acting on the material, so there is no additional heat loss. The air in the furnace and the corresponding container will not heat, so the thermal efficiency is particularly high, and the production environment is also significantly improved. Compared with far-infrared heating, it can save 30 % of electricity. 

3. Short heating time. Because microwave heating does not require heat conduction process, so the microwave penetrates the object from different directions into the interior of the object, from the inside to the outside so that the material in a very short period of time to achieve uniform drying, effectively shortening the drying time.

4, easy to control. Compared with the conventional method, microwave operation is simple ; the microwave power is adjustable and the transmission speed is adjustable.
