Technique for separating hemp seed and husk kernel

Abstract

The invention relates to a separation process of hemp seeds, shells and kernels, in particular to a separation process of hemp seeds, shells and kernels. The invention includes breaking shells, screening and separating shells and kernels, and the steps are divided into: A. removing impurities and grading; B. controlling moisture; C. breaking shells with double-toothed rollers; D. separating shells and kernels with vibrating sieves; E. Separation of shell and kernel with a non-net inclined vibrating screen; F. Packing separately. The separation process of the present invention can make the hemp seed have a shell content rate≤5%, a kernel content rate in the shell≤3%, and a total yield of more than 97%, so as to improve the sensory perception, internal quality, and economical quality of further deep-processed products. effect played a positive role.

Description

technical field [0001] The invention relates to a process for separating shells and kernels, in particular to a process for separating shells and kernels of hemp seeds. Background technique [0002] Fructus Cannabis, also known as hemp seed, hemp seed, pockmark. It is the fruit of the Moraceae plant Cannabis sativa L. In my country, the use of hemp seed as a raw material for the food industry has just started, and there is almost no technology dedicated to the processing of hemp seed, and the first step in the processing of hemp seed as a food raw material is to process the husk separate. As far as the primary processing of hemp seeds is concerned, the closest food processing technologies include cottonseed husk and kernel separation technology, rapeseed peeling technology and sunflower seed husk and kernel separation technology. At present, there are two kinds of mature peeling and shelling separation techniques applied to plants with shells at home and abroad: one is to ...

AI Technical Summary

Problems solved by technology

However, because the shell kernels of hemp seed are not much different in terms of specific gravity and size, especially after the shell is broken, 30% to 40% of the shell kernel mixture is very close in specific gravity, so it is difficult to separate them by winnowing and screening. They are separated, and it is difficult to meet the requirements of the corresponding technical indicators, that is, the technical requirements of the shell content in the kernel ≤ 5%, the kernel content in the shell ≤ 3%, and the total yield of 97%.
