Created Method to Remove Hard Walnut Shell

The common methods to remove the hard shell of walnut are as fellows:

1. impact method
Walnut at great speed V impact plate (or liner), after repeated impact after the implementation of walnut shell cracking, shell.
2. roll extrusion method
In shell peanuts, rice and other equipment in the use of a pair of steering instead, adjustable distance parallel roller hulling function realization.
3. rubbing method

The walnut is subjected to strong rubbing and shearing in the two pieces of moving and fixed teeth which are relatively moving, and the outer shell is broken and separated from the shell to achieve the purpose of shelling.

The above are common shell breaking methods. We can compare the characteristics of these methods by experiment, data, experience and even intuition. It can be seen that each method is not ideal for walnut shell removal. On the basis of summing up and analyzing, we should give full play to imagination and innovation, and propose two better methods:

Method 1: using many methods to improve the effect of shell breaking.
Another method is the combination of rubbing and impact. The feeding tray is used for turning the walnut out, and the walnut speed is impacted on the casing, so that the walnut kernel is combined with the shell to loosen the walnut kernel, and the crushing of the walnut kernel when rubbing and grinding is reduced.

Method two: the principle of extrusion method was improved to make the extrusion and rubbing action at the same time, and to increase the crack of walnut shell. This method is driven to rotate on the toothed disc under the walnut squeeze spacing of teeth continuously along the shell surface pressure, crack expanding, finally shell basically completely broken, broken shells and nuts fall through minimum clearance at.
