Coarse cereal flour and preparation method thereof

Abstract

The invention belongs to the technical field of food processing and particularly relates to coarse cereal flour and a preparation method thereof. The preparation method includes: (1) removing impurities; (2) weighing materials, adding into a mixer, spraying wetting liquid, stirring, mixing, discharging a mixture, spreading, centrifugally dripping, spraying salt water, and spreading to complete wetting; (3) milling the mixture, and separating out cortex, residues, cores and powder to obtain the coarse cereal flour. By mixing of coarse cereals before milling, problems of high energy consumption,low mixing efficiency and incompleteness in mixing after traditional coarse cereal milling are avoided. By adoption of the wetting liquid for wetting, bonding force of a cortex layer, an aleurone layer and endosperm is reduced through water adsorption of endosperm and the cortex layer before milling, and milling energy consumption differences of different materials are reduced; by mixing and mutual extrusion and friction of the different materials, milling efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to miscellaneous grain flour and a flour making method thereof. Background technique [0002] In daily life, the flour we refer to refers to wheat flour, that is, flour ground from wheat. According to the different protein content, flour is divided into high-gluten flour, medium-gluten flour and low-gluten flour. Traditional flour can only provide most of the calories, but cannot fully meet the needs of the human body in terms of nutrition. The nutrition is single and lacks health care effects. This requires a diversified diet and scientific and reasonable matching to achieve nutritional balance of flour. to meet the needs of the human body. [0003] Miscellaneous grains refer to crops rich in cellulose, protein, minerals and various vitamins, and usually refer to grain and bean crops other than the five major crops of rice, wheat, corn, soybean and potato; such...

AI Technical Summary

Problems solved by technology

In the prior art, traditional flour is rich in a variety of nutritional elements through certain mixing and matching, that is, various miscellaneous grains are ground into powder separately, and then various flours are put into the mixing equipment according to a certain proportion. The disadvantage of this is that in order to fully mix the miscellaneous grain flour, it needs to be stirred repeatedly, the energy consumption of the equipment is high, and it is uneconomical.
