Tartary buckwheat non-thermal shucking method and Tartary buckwheat shucking device

Abstract

The invention discloses a Tartary buckwheat non-thermal shucking method which includes the steps: removing impurities in raw materials; grinding the Tartary buckwheat raw materials by the aid of small contact force, grinding off protruding corner angle portions on Tartary buckwheat shells, and sufficiently grinding the corner angle portions on the Tartary buckwheat shells but not grinding endosperms and conical surface ventral groove recesses; enabling the shells to slightly deform by twisting, grinding or slightly striking, further fracturing the shells and finally separating the shells from kernels by an airflow cleaning method. By the novel method including non-thermal shucking, non-pressure grinding and the like, nutritional components are kept, shucking cost is low, shucking rate is high, and kernel breaking rate is low.

Description

technical field [0001] The invention belongs to the field of agricultural and by-product processing machinery, and in particular relates to a non-thermal shelling method of tartary buckwheat and a shelling device thereof. Background technique [0002] Tartary buckwheat is known as "the king of five grains". It not only has excellent nutritional and health value, but also contains special trace elements and medicinal ingredients that other food crops do not have. It is an internationally recognized crop with both medicine and food. my country is the country that grows tartary buckwheat in a large area in the world, with a cultivation area of ​​about 300,000 hm 2 , with an output of 300,000 to 500,000 tons, both of which rank first in the world. However, the amount of deep processing of tartary buckwheat in my country is relatively small, accounting for only about 5% of the total output. [0003] The shape of tartary buckwheat grains is a triangular pyramid structure, the co...

AI Technical Summary

Problems solved by technology

Because this method and equipment mainly rely on the large impact force to make the tartary buckwheat elastically deform, which will cause the husk to break, which will inevitably cause a large amount of tartary buckwheat kernels to be broken.
