The principle of work
When the damp raw material is fed from one material, it is turned over through blades that are distributed inside the cylinder and will be distributed uniformly in the drier and contact fully with the counter current hot air. In this way, the process of heat conduction is increased.During the period of dry, under the effect of inclined blades/or angled bafflers and hot air stream,raw material can be moved to the star section of drier and discharged from discharging value.
Features
1. The motorization level of the barrel is high, and the production
capacity is high;
2. The resistance that the material passes through the barrel is
less, and the power consumption is low.
3. Application capability to different characters of materials is
high.
4. The operation is stable, the operation fee is low, and the
uniformity of product drying is good.
