Microwave dryers are widely used in various places and have won the of the masses. What benefits can it bring us? Let's briefly introduce its related knowledge points by the editor below.
1. Fast heating speed: Conventional heating to external heating, while microwave heating belongs to internal heating. Electromagnetic energy directly acts on the medium molecule to convert it into heat, and the transmission makes the medium heat inside and at the same time, without the need for heat conduction, so it can achieve uniform heating in a short time.
2. Selective heating: Different materials have different absorption and of microwaves, that is, microwaves have the characteristics of selective heating, which is beneficial to the drying process. Because water molecules have a large absorption loss of micaves, the parts with high water content absorb more microwave power than the parts with low water content, so the drying rate tends to be consistent.
3. Energy-saving and: Glass, polyethylene, etc., hardly absorb microwaves, and metals reflect microwaves. These substances cannot be heated by microwaves. When microwave heating the heated material is usually placed in a metal-made heating chamber. Electromagnetic waves cannot be leaked and can only be absorbed by the heated object. The air in the heating and the corresponding containers will not be heated, so the thermal efficiency is high.
4. Uniform heating: When heated by external heating, in order to improve the heating speed it is necessary to increase the external temperature and increase the temperature gradient. However, it is easy to produce the phenomenon of scorching on the outside and raw on the inside. microwave heating, no matter what shape it is, microwave can penetrate evenly to produce heat, so the uniformity is greatly improved.
