Flour processing method

Abstract

The invention relates to the technical field of food processing, in particular to a flour processing method. A wheat wetting device used in the method comprises a material pool, a material barrel, a spiral pipe and a controller. The lower portion of the material barrel communicates with the material pool, and the height of the material barrel is three times that of the material pool. The section area of the material pool is two times that of the material barrel. A pump shell is arranged in the material barrel and located in the center of the material barrel. The pump shell is cylindrical, andthe side wall of the pump shell communicates with the spiral pipe. The spiral diameter of the spiral pipe is increased along with the increasing of the distance between the spiral pipe and the pump shell. According to the wheat wetting device used in the flour processing method, water and wheat grains are driven by an impeller to move, then the wheat grains are impacted on the inner wall of the material barrel through the spiral pipe to be matched, wheat bran is impacted to generate cracks, and therefore the endosperm wetting effect is improved, the endosperm and wheat bran separation effect and the flour yield are improved, and the flour production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a flour processing method. Background technique [0002] Flour is the staple food in most parts of northern China, and there are many kinds of food made from flour, with various styles and flavors; flour is a kind of powder made from wheat; according to the protein content in flour, it can be divided into high Gluten flour, medium-gluten flour, low-gluten flour and gluten-free flour; the process of wheat grinding and milling is mainly the process of separating wheat endosperm, bran, and germ; wheat bran wrapping accounts for about 18-25% of the grain weight; The germinated wheat germ only accounts for 1-2%; the endosperm accounts for about 70-80%, and there is aleurone layer adhesion between the endosperm and wheat bran; wheat grains are processed by milling process to separate wheat bran, wheat germ and endosperm Grinding the endosperm into flour for human consumption; ...

[0002] Flour is the staple food in most parts of northern China, and there are many kinds of food made from flour, with various styles and flavors; flour is a kind of powder made from wheat; according to the protein content in flour, it can be divided into high Gluten flour, medium-gluten flour, low-gluten flour and gluten-free flour; the process of wheat grinding and milling is mainly the process of separating wheat endosperm, bran, and germ; wheat bran wrapping accounts for about 18-25% of the grain weight; The germinated wheat germ only accounts for 1-2%; the endosperm accounts for about 70-80%, and there is aleurone layer adhesion between the endosperm and wheat bran; wheat grains are processed by milling process to separate wheat bran, wheat germ and endosperm Grinding the endosperm into flour for human consumption; and tempering is of great significance to the flour extraction rate of wheat grains. During the process of wheat tempering, after the wheat bran is soaked in water, its toughness is enhanced, preventing water from entering the endosperm, thus affecting the endosperm and the endosperm. The separation effect of wheat bran, which in turn affects the production efficiency

[0003] There are also some technical solutions about flour processing methods in the prior art. For example, a patent with an application number of CN201811440348.7 discloses a flour processing method. The technical solution includes the following steps: material preparation, wool-wheat ratio, The steps of net wheat blending, wheat moistening, grinding and so on; the grinding adopts 17 stages of grinding, that is, 8 core mills, 5 skin mills, 2 slag mills, and 2 tail mills. After grinding, sieve through sieve silk; The powder machine separates materials with the same particle size, namely, pure endosperm particles, fine bran particles, and even bran endosperm particles; the sieved flour of different grades is passed through 25-30 powder mixing pipes. The powder mixing system is used to mix the flour; through the combined use of the wool-wheat ratio and the net-wheat ratio, the content of dust mustard impurities, sand and stones, and grain impurities of different varieties in wheat is reduced to a very low level, so as to provide a good source for processing High-precision, high-quality flour has laid the foundation; however, this technical solution still cannot solve the problem that wheat bran blocks water from entering the endosperm during the wheat tempering process. limitation
