Microwave dryer, as the name implies, mainly uses microwaves for drying. Microwave is an electromagnetic wave of a specific frequency and wavelength, with a frequency between 300MHz and 300GHz, and a corresponding wavelength between 1 meter and 1 millimeter. Electromagnetic waves in this frequency range have the ability to penetrate materials and interact with water molecules in the material, causing the water molecules to vibrate and heat rapidly.

In a microwave dryer, the microwaves generated by the microwave generator are evenly transmitted to the drying cavity through a waveguide system. When these microwaves meet the water molecules in the material, they cause the water molecules to vibrate and rub at high frequencies, thereby generating heat. This internal heating method enables the material to heat up quickly and evenly, and effectively removes moisture to achieve the purpose of drying.

The advantages of microwave drying equipment are:

1. The product has good drying and shaping quality and does not crack;

2. It is easy to control and convenient and flexible to operate. Automatically control heating time and drying temperature;

3. Save time;

4. Less energy consumption;

5. Low production intensity and less space;

6. Save labor and process, especially easy to connect with previous and next processes into an automatic line to reduce the number of handling;

7. Environmentally friendly, clean and hygienic, pollution-free, and will not produce "three wastes".
