The peeling machine is mainly used for separation of the green walnut green and walnut, using a single walnut peeling process, along with cutting through broken skin, torsion straining, and casting skin process. In order to realize the continuous feeding and discharging, a special kick-off device was designed, by utilizing a series of repeat actions, including rotation-depression-torsion-reduction, finally achieve the separation of the green walnut pericarp from walnut. It turned out that the mechanical structure was compact and easy to operate as well as the knifes were systematized. Therefore, the appropriate tool can be replaced according to the specific utilization. The machine designed in this study showed the good prospects for the development and practice.
