Product Overview
　　The wet material enters the spiral bed from the top feeding port. Under the action of the circumferential excitation force and gravity, the material jumps along the spiral bed from top to bottom until the bottom; At the same time, the clean hot air enters from the bottom of the spiral bed and is discharged from the top moisture outlet after sufficient heat and mass transfer with the materials distributed on the bed. Thus, the material can be dried.
Product application
　　The drying equipment product is mainly applicable to the drying of traditional Chinese medicine pills; It can also be applied to the drying of granular, short strip and spherical materials in industries such as chemical industry, restriction, food, plastics, building materials, feed, etc.
Main features

● The hot air passes through the material layer for many times and flows in reverse with the material, making the heat exchange sufficient and the heat efficiency high.

● Compact structure and small floor area.

● The retention time of materials in the bed can be adjusted, and the operation is convenient.

● When the material moves in a circle from bottom to top along the spiral bed, it also jumps itself, thus increasing the contact between the material and the hot air and enhancing the drying effect.

● Continuous feeding and discharging is suitable for assembly line operation and easy to reach the "GMP" specification, which can replace the traditional box-type drying.

● There is no damage to the surface and shape of the material, which not only ensures the roundness of the pills, but also greatly reduces the crushing rate of the pills.
