Automatic walnut sheller and shelling process

Abstract

The invention discloses an automatic walnut sheller and a shelling process. The sheller comprises a storage barrel, a walnut sorting mechanism, a walnut peel grinding mechanism, a conveying mechanism and an extrusion shell breaking mechanism which are sequentially arranged in the walnut advancing direction. A first discharging pipe is arranged on the material storage barrel, a sorting feeding port and a plurality of second discharging pipes are arranged on the walnut sorting mechanism, a plurality of feeding areas and a plurality of peel grinding discharging ports are arranged on the walnut peel grinding mechanism, and a conveying feeding port and a conveying discharging port are formed in the conveying mechanism. The extrusion shell breaking mechanism is provided with a shell breaking feeding port and a collecting box, the first discharging pipe is communicated with a sorting feeding port of the walnut sorting mechanism, the second discharging pipes are arranged above a corresponding feeding area, the peel grinding discharging port is arranged above a conveying feeding port of the conveying mechanism, and a conveying discharging port of the conveying mechanism is arranged above the shell breaking feeding port. After the shell of a walnut is broken by the sheller, the integrity of the walnut kernel is high.

Description

technical field [0001] The invention relates to the technical field of walnut shelling, in particular to an automatic walnut shelling machine and a shelling process. Background technique [0002] Before walnuts are processed into walnut slurry, walnuts need to be shelled before processing. Walnuts with a shell thickness of less than 1.5mm are thin-skinned walnuts, and walnut shells with a thickness of more than 1.5mm are thick-skinned walnuts. Most of the shelling machines are extruded. Traditional walnut shelling equipment, for thin-skinned walnuts, the walnuts can be shelled with a small extrusion force without excessive damage to the walnut kernel, but for thick-skinned walnuts In terms of walnut shell, because the walnut shell is extremely hard, the extrusion force is not easy to control. If the extrusion force is too small, the walnut shell breaking rate is not high, and the unshelled walnut needs to be re-shelled. It is easy to be crushed, and the integrity of the ker...

Problems solved by technology

[0002] Before walnuts are processed into walnut slurry, walnuts need to be shelled before processing. Walnuts with a shell thickness of less than 1.5mm are thin-skinned walnuts, and walnut shells with a thickness of more than 1.5mm are thick-skinned walnuts. Most of the shelling machines are extruded. Traditional walnut shelling equipment, for thin-skinned walnuts, the walnuts can be shelled with a small extrusion force without excessive damage to the walnut kernel, but for thick-skinned walnuts In terms of walnut shell, because the walnut shell is extremely hard, the extrusion force is not easy to control. If the extrusion force is too small, the walnut shell breaking rate is not high, and the unshelled walnut needs to be re-shelled. It is easy to be crushed and the integrity of the kernel is not high. Therefore, it is necessary to develop a shelling equipment and shelling method mainly for thick-skinned walnuts in order to improve the shell breaking rate and kernel integrity of thick-skinned walnuts.
