In the process of rolling and moving, the bunched or stacked cane is contacted with the stripping nails on the stripping paddle and stripping column in multiple directions and multiple times, and is cut open and scattered. The leaves wrapped around the cane are partially stripped, and the impurities such as mud and leaves mixed in the raw cane fall into the first-stage collecting chute from the screen gap of the first-stage screen cylinder, completing the first-stage stripping and impurity removal of the raw cane. Subsequently, the raw cane rolls and moves to the intermediate connecting cylinder, enters the second-stage screen cylinder, and continues to roll and move along the screen cylinder wall under the pushing of the spiral-distributed stripping paddle and stripping column. Through continuous all-directional frictional contact with the densely distributed stripping column, the leaves wrapped around the cane are stripped completely, and the stripped leaves fall into the second-stage collecting chute from the screen gap of the second-stage screen cylinder, completing the second-stage stripping and impurity removal of the raw cane. The raw cane rolls and moves from the second-stage screen cylinder to the discharge cylinder, and falls into the conveying equipment of the sugar mill production line from the discharge cylinder.
