Abstract: A nut shelling apparatus and method for the shelling of nuts such as chinquapins and chestnuts without substantially damaging the meat of the nuts. The nut shelling machine utilizes a combination of the inertia of the nut and a planar rotating cutting disc, such as one with a layer of aluminum oxide abrasive material, to cut the shell of the nut in a series of small cuts. The rotating abrasive disc utilizes the resistive inertia of the nuts to launch the nut in an upward direction and causing the nuts to fall onto the abrasive surface to repeatedly cut the shells. The repeated cutting action results in removal of a substantial amount of the shell in a short period of time while at the same time minimizing damage to the meat of the nut.
