Pricinple :

The wet material enters the spiral bed through the top feeding port. Under the action of circumferential excitation force and gravity, the material jumps from top to bottom along the spiral surface until the bottom layer discharges; meanwhile, the clean hot air enters from the bottom of the spiral bed. After sufficient heat transfer and mass transfer with the materials distributed on the bed, the residual hot air and moisture are discharged from the top exhaust port, and the dried material is discharged from the discharge port at the bottom of the dryer.

 

 

 

Application

This product is mainly suitable for the drying of Chinese medicine pills. It can also be used for drying of granular, small spherical, short strip, short filament and other materials in various industries such as pharmaceutical, chemical, food, plastic, electronics, building materials, food, feed and so on. .

Features:

1. The hot air passes through the material layer multiple times, and moves backwards with the material, so that the heat exchange is sufficient and the heat efficiency is high.

2. Compact structure and small footprint.

3. The residence time of the material in the dryer can be adjusted and the operation is convenient.

4. While the material moves circumferentially from top to bottom along the spiral bed, it also jumps itself, which increases the contact area between the material and the hot air and enhances the drying effect.

5. Continuous feed and discharge is suitable for production line and easy to meet the "GMP" specification, which can replace the traditional box drying.

6. There is basically no damage to the surface and shape of the material, which not only ensures the roundness of the pellet, but also greatly reduces the breaking rate of the pellet.
