Shell breaking equipment capable of reducing surface damage of walnut kernels

Abstract

The invention discloses shell breaking equipment capable of reducing surface damage of walnut kernels. The shell breaking equipment comprises a machine shell, an air drying assembly, a grading assembly, shell breaking assemblies and a shell-kernel separating device, wherein a feeding hopper is mounted at the top end of the machine shell and is used for introducing walnuts to be subjected to shellbreaking into the equipment. The shell breaking equipment is characterized in that the air drying assembly is arranged at the upper end of the interior of the machine shell and is used for drying thewalnuts to be subjected to shell breaking, so that the dried walnuts enter the grading assembly; the grading assembly is arranged at the right end of the interior of the machine shell, and a grading chamber is formed by the grading assembly and the inner wall of the right side of the machine shell and is used for grading the walnuts according to the size; the multiple shell breaking assemblies aremounted in the machine shell, respectively communicate with the grading assembly and are used for breaking the shells of the walnuts; and the shell-kernel separating device is further arranged on theleft side of the interior of the machine shell and is used for separating the shells and the kernels of the walnuts subjected to shell breaking, so that the relatively complete walnut kernels are collected.

Description

technical field [0001] The invention belongs to the technical field of agricultural product processing, in particular to a shell breaking device capable of reducing surface damage of walnut kernels. Background technique [0002] As one of the four major nuts in the world, walnut kernels have high nutritional value and are deeply loved by people. Since the walnut shell is relatively hard, a shell-breaking equipment is needed to break the shell. However, according to the survey, it is currently The existing walnut shelling equipment often has the following problems: [0003] 1. The walnuts are not fully dried before the shells start to break, which makes it difficult to break the shells, and even breaks together with the walnut kernels; [0004] 2. Concentrate walnuts of different sizes and use a fixed shell breaking device to break their shells, resulting in incomplete shell breaking of smaller walnuts, and damage to walnut kernels by larger walnuts, which cannot guarantee t...

AI Technical Summary

Problems solved by technology

[0003] 1. The walnuts are not fully dried before the shells start to break, which makes it difficult to break the shells, and even breaks together with the walnut kernels;

[0004] 2. Concentrate walnuts of different sizes and use a fixed shell breaking device to break their shells, resulting in incomplete shell breaking of smaller walnuts, and damage to walnut kernels by larger walnuts, which cannot guarantee the effect of shell breaking. The equipment uses a one-time extrusion shell breaking method, which cannot guarantee the integrity of the walnut kernel after shell breaking;

[0005] 3. After the walnuts are broken by the existing shell breaking equipment, a vibrating screen is used to separate the shell kernels. Not only the separation effect is poor, but also the walnut kernels are more likely to be damaged
