Background technique

Dietary fiber is a nutrient that maintains human health and cannot be replaced by other substances. It is a general term for a complex mixture. People refer to it as the six major nutrients following carbohydrates, fats, proteins, vitamins, water and minerals. Other than the "seventh nutrient" of the human body. The surface of wheat bran, bean dregs, and corn husks all contain lipids and lignin. If they are directly crushed, they will not only have poor eating quality, but also fail to achieve the effect of dietary fiber.

For example, winter wheat is a variety of wheat grown in warmer places. It is generally sown from mid to late September to early October, and matures from the end of May to mid to late June of the following year. my country is dominated by winter wheat. When wheat is processed into wheat kernels after harvesting, it is necessary to remove the wheat bran from the outer layer of the wheat granules, leaving only the high-gluten flour part of the wheat granules, which is used for people to cook porridge, etc., and the taste is better. However, at present, the operation of removing the surface layer of wheat bran from grain particles is usually carried out by manual hammering, which is inefficient and difficult to separate the wheat bran and the wheat kernel.
