The object to be processed generated in the front portion tends to easily flow into the processing chamber 18.

Also, the amount of material to be processed is small in the rear part of the handling chamber 17, and most of the material to be processed generated in the front part is small due to outflow into the processing chamber 18 and leakage from the threshing net 19. ing. On the other hand, in the rear part of the processing chamber 18 corresponding to the rear opening communication part K, the ring collar body 3 is provided.
Since it is partitioned by 2 and is located on the transfer end side in the processing chamber 18, a large amount of the object to be processed is transferred from the front.

Therefore, the object to be processed flows into the processing chamber 18 from the handling chamber 17 at the opening communication portion K at the front end and the opening communication portion K at the front portion, and conversely at the opening communication portion K at the rear portion. It tends to flow out from the chamber 18 to the handling chamber 17. It should be noted that the processing chamber 18 in the opening communication part K at the rear part
The discharge from the discharge chamber to the handling chamber 17 is promoted in the arrow (d) direction by the emitter 31.
