Abstract: The present invention is related to an apparatus for peeling off, and is composed of an opening through which water is introduced; a cylinder including a plurality of blades for peeling off attached in a row on the inner side of it; a rotating bottom plate which is arranged on a lower part of the cylinder, and which includes opposing convex portions formed on a part around an axis, and a projection rotatively installed on the surface of the bottom plate; a motor mounted on the lower part of the rotating bottom plate for rotating the rotating bottom plate forwardly and inversely; an outlet connected to the cylinder for discharging the remaining water and shells after peeling off; and a discharge opening for pulling out remaining materials in the cylinder. If a motor is operated after pouring the water and the materials into the cylinder, the water and the materials are rotated along the circumference of the cylinder according to the rotations of the rotating bottom plate.
