The more you know about flour, what is the technological process of making flour from wheat?

1. cleaning: mainly clean up the impurities such as straw, gravel and damaged wheat that affect the flour yield. The main equipment includes: thresher, stone remover, winnowing machine, concentrator, etc. According to the quality and milling requirements of wheat, there will be some differences among flour mills.

2. Waterlogging: After wheat is washed, it needs to be waterlogged to make the water content of wheat reach a certain level, which can improve the toughness of wheat bran and reduce the mechanical strength of wheat endosperm, so that wheat bran can not be ground into pieces during milling, which will affect the quality of flour, and the tempered endosperm will reduce the wear of the grinding roller of the mill and reduce energy consumption. Generally, high-gluten wheat needs more water, while low-gluten wheat needs less water.

3. Moisten wheat: Wheat with water should be stored in the wheat barn for a certain period of time, usually 8-24 hours, depending on the wheat variety and temperature. High gluten wheat generally takes longer, and it takes longer to moisten wheat in winter. The soaked and wet wheat is called broken wheat, and the water content of broken wheat is controlled at 14~ 16%. If it is too high, it will affect the later screening mechanism.

4. Crushing and sieving: dispersion crushing system and hulling crushing system, in which wheat is crushed into big chaff, small chaff, big endosperm, small endosperm and coarse powder by pulverizers, and then different materials are crushed by different pulverizers, and simultaneously screened and cleaned. This is a very complicated process, which needs to be adjusted by an experienced pulverizer to achieve the best effect. Finally, flour (1~3 kinds), coarse bran and fine bran were obtained.

5. Flour blending: Due to the demand of special flour, the flour ground from one kind of wheat often fails to meet the requirements of customers. By mixing different wheat flour in a certain proportion, the flour properties of the finished flour can be adjusted to meet the requirements of customers.

Finally, packaging.

Equipment configuration, production capacity and technology are different, prices are often different, and profits are different from peers. It's a long story.
