Background
Traditional flour processing is carried out by the following steps: firstly, screening is carried out, and the vibrating screen is used for screening out impurities in the wheat, so that the wheat is clean and free of impurities, and the quality of the flour is higher. After that, the wheat is washed by water spraying, which is mainly used for cleaning the wheat more cleanly, guaranteeing the sanitation of the flour and being beneficial to the later wheat peeling. Then the wheat is conveyed, and is transported up by a conveyer belt, and is sucked up by vacuum by a pipe processed by white iron. And then flour is ground, the special flour mill equipment can grind the flour up and down, and flour can be produced easily by continuous processing. Finally screening, the milled mixed coarse powder falls into a screening mechanism, so that the flour and the wheat bran are separated efficiently, and the embryo is extracted.
However, in the conventional processing method, multiple times of grinding are required in the grinding process to obtain finer flour.
