Introduction
Microwave drying is an emerging drying method.
When drying, the microwave energy directly acts on the medium molecules to convert into heat energy, and the microwave itself has strong penetrability. The dried objects can be heated simultaneously inside and outside, so when using microwave heating, there is no external ripening. In the case of life, heat conduction is not required, so the heating rate is very fast, and regardless of the shape of the object to be heated, the microwave is extremely strong, and the temperature inside and outside of the object to be heated is almost uniform, and the heating is uniform, which greatly improves. Dry quality and dewatering effect.
