Shelling device aiming at Chinese chestnuts

Abstract

The invention discloses a shelling device aiming at Chinese chestnuts. The device comprises: an extrusion roller which is horizontally arranged, wherein a plurality of convex ribs which are parallel to the axis of the convex ribs are distributed on the outer surface of the extrusion roller; a kneading and rubbing roller which is arranged under the extruding roller in parallel, wherein the kneadingand rubbing roller is provided with a plurality of elastic scraping plates; a cage grid which is arranged below the kneading and rubbing roller, wherein the cage grid is provided with a curved-surface grid, the curved-surface grid is provided with a hole through which Chinese chestnuts pass, the self axis of the curved-surface grid is superposed with the self axis of the kneading and rubbing roller, and the radial distance between the curved-surface grid and the kneading and rubbing roller is smaller than the radial distance between the top of the scraping plates and the kneading and rubbingroller when the scraping plates are not pressed; and a shell which is used for wrapping the extrusion roller, the kneading and rubbing roller and the cage grid, wherein the top of the shell is provided with a feed hopper, the bottom of the shell is provided with a discharge hopper, and a gap exists between the cage grid and the discharge hopper. The extrusion roller and the kneading and rubbing roller are provided with rotating driving power. The device is combined with an extrusion method and a kneading and rubbing method to remove shells, the chestnuts are fully stirred, and the shelling effect is uniform.

Description

technical field [0001] The invention relates to the field of nut shelling equipment, in particular to a chestnut shelling device. Background technique [0002] The main chestnut shelling methods on the market now include manual shelling, chemical shelling, baking shelling, energy shelling and mechanical shelling. However, the manual shelling method has high work intensity and is unhygienic; the chemical shelling method will affect the structural components of chestnuts; the baking shelling method is difficult to operate and is not easy to control; the energy shelling method is expensive, so these four methods are not suitable. Used by most processing companies. As a nut, chestnut has a hard shell and a large size. Chestnut is different from other nuts, such as peanuts, melon seeds, walnuts, etc. The shell is hard, and there is no joint seam on the surface. There is a gap between the shell and the chestnut kernel. The red coat that is tightly combined with the chestnut kern...
