Highland barley processing technology

Abstract

The invention provides a highland barley processing technology which comprises a highland barley milling section. The technology is characterized by further comprising color sorting carried out on milled highland barley. A fine sorting function is added in the moisten highland barley cleaning process, and therefore foreign grains, incomplete grains, round beans and buckwheat can be separated out; in the highland barley milling section, four to seven emery rolls and one to two iron rolls are combined to work, the whole rice percentage can reach 80% and is improved by more than 10%, processing precision is ensured, the broken rice rate is reduced, and fine processing is achieved; before fine highland barley is packaged, color sorting for fine highland barely is increased, it is ensured that the product contains no impurity or incomplete grains such as immature grains, grains damaged by insects, spotted grains, mildew grains and brown rice grains, and food safety and dietetic hygiene are ensured; the finished product is automatically stacked after being packaged, the number of workers of enterprises is greatly reduced, the labor intensity is reduced, and mechanical work is achieved. All the working procedures can be completed through machines, and fine, large-scale and automatic production of highland barley can be achieved.

Description

technical field [0001] The invention belongs to the field of miscellaneous grain processing, in particular, the invention relates to a processing technology of highland barley rice. Background technique [0002] The seeds of highland barley are caryopsis, and the kernels are naked, completely separated from the chaff. The grains are 6-9mm long and 2-3mm wide, with spindle-shaped, oval, diamond-shaped, cone-shaped, etc. Highland barley grains have a smoother surface than barley with a variety of colors, such as yellow, gray-green, green, blue, Red, white, brown, purple and black etc. Highland barley consists of three parts: embryo, endosperm and cortex. There are no ectodermal leaves in the embryo, and there are 4 differentiated leaf primordia in the embryo. The endosperm contains more starch and less gluten. The grain contains 45% to 70% starch and 8% to 14% protein. Highland barley has rich nutritional value and special effects, and is mainly rich in β-glucan, which is 5...

AI Technical Summary

Problems solved by technology

However, the existing highland barley rice processing technology is simple, and there is no control measure for the heterochromatic grains and mildewed grains in the highland barley rice, and the produced highland barley rice has poor color and low quality
