1. Cleaning: mainly clean up the wheat in the straw, stone, broken wheat and other impurities affecting the flour yield. The main equipment are: wheat machine, to stone machine, wind selection, selection, etc., according to the quality of wheat and flour requirements, a variety of flour mills will be some difference
2. water: wheat cleaned up after the need for water, so that the moisture of wheat to reach a certain content, you can improve the toughness of the wheat husk, reduce the mechanical strength of the endosperm of wheat so that in the milling, so that the husk should not be ground to a very crushed and affect the quality of the flour, and the tempering of the endosperm makes the milling machine. The endosperm makes the grinding roller of the milling machine less abrasive, and reduces energy consumption at the same time. Generally high gluten wheat with more water, low gluten wheat is relatively less.
3. Wetting wheat: the wheat with water in the silo to be stored for a certain period of time, generally in 8 to 24 hours, according to wheat varieties, temperature varies. High-gluten wheat is generally longer, winter wetting time is also longer. After water and wetting wheat is called into the milling wheat, into the milling wheat moisture control in 14 ~ 16%. If it is too high, it will affect the latter sieving.
4. Grinding and sieving: the center milling system and the skin milling system, the milling machine will break the wheat into large bran, small bran, large endosperm, small endosperm, coarse powder and fine powder, and then different materials into different mills to grind, and at the same time with the sieving and clearing of powder. This is a very complicated process, which needs to be adjusted by experienced millers to achieve the optimal result. Finally you get flour (1~3 kinds), coarse bran, fine bran.
5. Matching flour: Due to the demand for specialized flour, the flour milled from one kind of wheat often fails to meet the requirements of the customers, through the mixing of different wheat flours according to a certain proportion, the finished flour can be adjusted to meet the requirements of the customers by adjusting the various characteristics of the flour.
