[0019] Furthermore, the pressing shaft rotates in opposite directions to the stem conveying shaft, thereby facilitating the stems to be concentrated on the cutting wheel for cutting and crushing.

[0020] Under the action of the inclined baffle (ginger guiding plate), the stems with ginger are conveyed onto the stem conveyor belt, and the ginger is conveyed onto the ginger conveyor belt on one side of the stem conveyor belt. As the conveyor belt advances, the stems are concentrated at the cutting wheel and the slicing wheel. Under the action of the pressing belt, they are pressed, and the ginger and the stems are sliced by the cutting wheel, and the stems are cut into multiple sections by the slicing wheel.
