The thermal energy adjusting rod 9 can adjust the distance between the thermal energy generating device 5 and the material vibration device 7, so as to solve the problem of moisture uniformity and prevent excessive drying of different materials 6. At the same time, the heat energy generating device 5 can also directly dry the core of the material 6, so as to solve the phenomenon that the material 6 is difficult to dry.

The heating unit is composed of one or more heating elements in a micro-molecular nano-coating heating plate, a far-infrared silicon carbide electric heating plate, and a far-infrared heating tube.

The drying box 12 is distributed with a multi-layer bearing plate and a heating unit, and the vibration adjustment mechanism adjusts the inclination angle of the bearing plate. The material vibration device 7 is designed with vibration adjustment rods 10 at the front and rear, which can adjust the inclination of the material bearing plate of the material vibration device 7 when different drying unit boxes are connected.

The support plate is a sieve plate, a screen mesh or a glass plate. When the material bearing plate is a penetrable material such as a sieve plate, a screen mesh or glass, the thermal energy generating device 5 can be designed above and below the sieve plate, the mesh mesh or the glass.
