What is the difference between a single-layer rotary dryer and a three-layer rotary dryer?

Second, In terms of drying effect.

The drying effect of the three-layer rotary dryer is better. 

Since the equipment has multiple cylinders, the material and the hot air flow are exchanged in the form of radiation, convection and conduction in the inner cylinder, and the heat exchange in the outer cylinder is combined in the form of conduction and convection.

The drying effect is obvious.

The operating parameters are also more reasonable.
