A cracking device capable of reducing surface damage of walnut kernels

Abstract

The invention discloses a device for cracking walnut kernels that can reduce surface damage, which includes a casing, an air-drying component, a grading component, a cracking component and a shell kernel separation device, wherein a feeding hopper is installed on the top of the casing, It is used to introduce the walnuts to be cracked into the equipment, and it is characterized in that: the upper end of the inside of the casing is provided with an air-drying component, which is used to dry the walnuts to be cracked, so that the dried walnuts enter the grading component; the grading component It is installed at the right end inside the casing, and forms a grading chamber with the right inner wall of the casing, which is used for grading walnuts; multiple shell breaking components are installed inside the casing, and are respectively connected with the grading components, It is used to crack the shell of walnuts; the left side of the inside of the casing is also equipped with a shell and kernel separation device, which separates the shells and kernels of the broken walnuts so as to collect relatively complete walnut kernels.

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
