4. Material is constantly stired in middle, two steps forward one step back approach.

5. In the middle, the material fully absorb the inner drum heat, and the middle drum heat, while extending the drying time, the material achieve the best dry condition here.

6. The material move to the end of the middle into the outer layer, and it marching in rectangular multi-loop method.
