The receiving and cooling assembly is located at the bottom of the feeding auger 1 to cool and collect the cut particles.

[0037] In one embodiment of the present invention, the gear shaft 10 is driven by a drive motor 15 mounted on a bracket 14, and the drive motor 15 is also electrically connected to an external controller.
