The amount of adhering branches, etc. is increasing. In the first half of the dust feeding port processing cylinder 21, the charged shoots adhering grains and the like are processed while being conveyed backward, and the first half of the dust feeding port processing cylinder 21 is used as a parallel processing cylinder.
[0026]
Then, the soot and soot that cannot be processed in the first half of the dust feeding port processing cylinder 21 are conveyed to the latter half of the dust feeding port processing cylinder 21 as they are. On the other hand, the edible infarction particles and the like that could not be processed by the handling cylinder 20 are introduced into the middle part of the front and rear of the dust feeding port processing cylinder 21 from the rear side of the handling cylinder 20, and are conveyed from the front half of the dust feeding port processing cylinder 21. Together with the sawdust etc., it is conveyed to the latter half part of the dust feeding port processing cylinder 21. In the latter half of the dust-feeding port processing cylinder 21, processing is performed while conveying soot waste, branch stick-attached grains and the like backward, and the soot is discharged from the rear end of the dust-feeding port processing cylinder 21 to the outside of the machine. Therefore, the front half part and the latter half part of the dust feeding port processing cylinder 21 have different functions, and the leakage performance of the handling cylinder 20 is improved, and the treatment of branch rachis adhering grains and the like is reliably performed.
[0027]
