Description

Primary crushing device for whole wheat flour

Technical Field

The utility model relates to a primary crushing device of whole wheat flour, belongs to the field of grain and oil processing facilities, and particularly relates to a device for cutting wheat into pieces by a blade before grinding.

Background

Whole wheat flour, mixed powder of crushed seed coats, endosperm, cotyledon, embryo buds, hypocotyls and radicle. However, most of the flour consumed by us is the flour which is removed of the skin and germ, and the nutrition in the flour is partially lost. When the existing flour processing enterprises process whole wheat flour, as the wheat is the seed coat which is most difficult to grind, three-stage serial flour mills are adopted, namely, a first-stage flour mill is primary mill, a second-stage flour mill is fine mill and a third-stage flour mill is fine mill, and the qualified whole wheat flour can be obtained through three-stage differential roller grinding. However, the differential rollers of the primary flour mill and the secondary flour mill wear faster and the matched power is larger, because the seed cortex of the wheat is hard and difficult to crush, so that the differential rollers of the primary flour mill and the secondary flour mill are tightly adjusted, the wear is too fast, and the equipment cost and the power consumption are increased. Therefore, a facility capable of crushing the wheat husks in advance is required to reduce the wear of the differential drum and the power consumption.
