A method for crushing pure natural wild iron walnuts and separating kernels and shells

Abstract

The invention discloses a method for crushing pure natural wild iron walnuts and separating kernels and shells, comprising the following steps: soaking: soaking the iron walnuts in clear water to obtain soaked iron walnuts; crushing in the machine to obtain crushed iron walnut particles mixed with kernels and shells; classification: put the crushed iron walnut particles mixed with shells and kernels in a sorting machine for sorting to obtain large particles of crushed iron walnut particles on the sieve and small particles Crushed iron walnut particles under the sieve; drying: drying the crushed iron walnut particles under the sieve to obtain dry iron walnut particles mixed with kernels and shells; separation of kernels and shells: placing the dried iron walnut particles mixed with kernels and shells in a color sorter Color sorting and separation, that is, to obtain separated walnut shells and walnut kernels. The pure natural method for crushing wild iron walnuts and separating kernels and shells has the advantages of simple process, safety and environmental protection, convenience and high efficiency.

Description

technical field [0001] The invention relates to the technical field of crushing and kernel shell separation methods, in particular to a pure natural wild iron walnut crushing and kernel shell separation method. Background technique [0002] Iron walnut is a kind of pure natural wild walnut, which is mainly distributed in Yunnan, southeastern Tibet, southern Sichuan and other places. Wild iron walnut has high nutritional value and commercial value. The kernel content rate of iron walnut is about 14% lower. The shell of wild iron walnut is hard. Rich in omega-3 linolenic acid, omega-6 linoleic acid and rich in various trace elements and vitamins. The wild iron walnut oil is moist and refreshing, with a mellow and long-lasting fragrance, and more than 70% of the ingredients in the walnut oil are linoleic acid and linolenic acid. In order to utilize it, it is very difficult to separate the shell and kernel in the processing process, which has been a major obstacle for people t...

AI Technical Summary

Problems solved by technology

[0003] Because the wild iron walnut skin is very hard and the shape of the kernel is irregular, ordinary walnut peeling technology cannot be applied to wild iron walnuts. The current method of shelling wild iron walnuts is completely manual sorting, which is not only labor-intensive and time-consuming, but also efficient. Low, it is impossible to form an industrialized iron walnut industry processing base, which makes it difficult to use wild iron walnut kernels, and a lot of resources are wasted

At present, there are no methods and complete sets of equipment specifically for the crushing of wild iron walnuts and the separation of kernels and shells in the market. Therefore, it is necessary to study a method for crushing wild iron walnuts and separation of shells and kernels.
