Technical Field

The invention relates to the field of flour processing, in particular to a flour processing technology.

Background

Flour is a powder ground from wheat. According to the content of protein in the flour, the flour can be divided into high gluten flour, medium gluten flour, low gluten flour and non-gluten flour.

Flour (wheat flour) is staple food in most areas in the north of China, and foods made of the flour are various in variety, various in shape and different in flavor.

The existing flour has complex processing technology, destroys the nutritional ingredients of the flour and is not beneficial to long-term eating by people.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provides a flour processing technology to solve the problems that the existing flour processing technology is complex, destroys the nutritional ingredients of flour and is not beneficial to long-term eating of people.

The invention is realized by the following technical scheme:

the invention provides a flour processing technology, which comprises the following steps:

(1) cleaning the wheat to remove impurities;

(2) screening impurities by using a high-efficiency vibrating screen, separating heterochromatic particles in the wheat by using a color separator, and separating metal impurities in the wheat by using a circular magnetic separator;

(4) after 5-pass skin milling and 8-pass core milling, the wheat obtained in the step enters a 2-pass ball milling stage, then 2-pass tail milling is carried out, and the bran, the aleurone layer and the wheat core part of the wheat are separated through extrusion and friction of grinding rollers with different speed ratios;

(5) the method comprises the following steps of (1) effectively separating three materials with different textures, namely pure endosperm particles, fine bran particles and bran endosperm particles, which have the same granularity by using a purifier, wherein the cleaned pure wheat is required to have an impurity standard: not more than 0.1%;

(6) grading flour by using a square sieve, mixing the graded flour by using a flour mixing system, and grading the flour with different granularities and different parts in the wheat by using the square sieve for screening by using sieves with different apertures;

(7) checking and accepting, and packaging: and sealing the finished product bag filled with the wheat flour by using an electronic packing scale.

As a preferable scheme of the scheme, the step (1) is specifically to accept raw material wheat, meet GB1355 sanitary requirements and meet company quality standards, use a high-efficiency vibrating screen for primary screening, then use a specific gravity grading and stone removing machine for separating miscellaneous stones from the wheat, and control the air volume to be between 5 and 6 through a screen surface through which air flows by utilizing the different specific gravity of the wheat and the stone, so that the wheat and the stone are separated.

As a preferable scheme of the scheme, the impurities of the dust mustard after being cleaned in the step (2) are less than or equal to 0.09 percent, wherein the content of sand and stone is less than or equal to 0.09 percent, and the content of grains of different varieties is less than or equal to 0.09 percent.

Compared with the prior art, the invention has the following advantages: the flour disclosed by the invention is simple in processing technology, the nutritional ingredients of the flour are not damaged, and the flour is beneficial to being eaten by people for a long time; the flour processing technology is environment-friendly, the cost is low, and the prepared flour is fine and smooth and has good taste.
