Flour screening is an important step in the flour processing process. It is usually carried out using equipment such as vibrating screens or rotary vibrating screens. The purpose of screening is to classify the flour according to particle size and remove impurities and large particles to obtain purer and more uniform flour.

[0003] Patent No. CN202221985492.0 proposes a feeding device for flour processing, in which a driving device pushes an arc-shaped rack to rotate around a hinge point of a pushing arc plate, and the arc-shaped rack pushes the rotation, pushing the arc plate and the arc-shaped fixed rod to move relative to each other, and the arc-shaped baffle and the sliding cavity compress the arc-shaped spring. When the driving device and the arc-shaped rack are disengaged, the compressed arc-shaped spring pushes the arc plate to reset through the arc-shaped fixed rod and the arc-shaped baffle, and then pushes the arc plate to prevent flour accumulation inside the storage box in a reciprocating swing. It cannot feed in multiple stages, and cannot perform multi-stage screening while feeding in multiple stages. Therefore, a person skilled in the art provides a feeding device with a screening function to solve the problem that it cannot feed in multiple stages, and cannot perform multi-stage screening while feeding in multiple stages.
