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.

Abstract

The invention discloses a method for crushing purely natural wild juglans sigillata and separating kernels from shells. The method comprises the following steps of performing soaking: placing the juglans sigillata in clean water for soaking so as to obtain soaked juglans sigillata; performing crushing: placing the soaked juglans sigillata into a crushing machine for crushing so as to obtain crushed juglans sigillata granules of which kernels and shells are mixed; performing classifying: placing the crushed juglans sigillata granules of which the kernels and the shells are mixed into a sorting machine for sorting so as to obtain large crushed juglans sigillata granules on a sieve and small crushed juglans sigillata granules under the sieve; performing drying: performing drying treatment on the small crushed juglans sigillata granules under the sieve so as to obtain dried juglans sigillata granules of which the kernels and the shells are mixed; and performing kernel-shell separation: placing the dried juglans sigillata granules of which the kernels and the shells are mixed in a color selector for color selection separation so as to obtain separated juglans sigillata shells and juglans sigillata kernels. The method for crushing purely natural wild juglans sigillata and separating kernels the shells is simple in technology, safe, environmentally-friendly, convenient and high-efficient.

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...
