Description

Technical Field

[0001] The utility model relates to the technical field of flour raw material processing, and more specifically to a raw material impurity removal device for flour production. Background Art

[0002] Flour is a powdered food made from wheat. The wheat purchased from the market is often mixed with various large and small gravel, ironware and other debris.

[0003] At present, in the process of wheat processing, the wheat needs to be filtered and impurities are removed by a de-impuring device. However, when the de-impuring device is used and when adding materials, it is easy to cause the wheat to pile up, which reduces the uniformity of spreading and is easy to spill. In addition, the removal area of ​​iron impurities in the wheat is small, resulting in incomplete removal of iron impurities in the wheat.

[0004] For example, announcement No. CN112452706A discloses a wheat impurity remover for flour processing, which includes a hopper and a screening drum. The hopper is arranged above the center of the screening drum. The lower end of the hopper is connected to a feed pipe that extends into the screening drum. A turntable is arranged directly below the feed pipe. A large number of first sieve holes are formed in a rectangular array on the outer edge of the turntable. The outer end face of the turntable is connected to a material retaining ring that is tilted and tilted upward.

[0005] It can be seen from the above-mentioned public scheme that wheat added to the surface of the turntable tends to accumulate in the middle position. At the same time, the turntable rotates, and the wheat is easily spilled out of the turntable under the action of centrifugal force. In addition, when iron impurities are removed by annular electromagnets, the adsorption area is small and the removal is not thorough. Utility Model Content
