The Purifier is an indispensable equipment in the flour mill. It uses the combined action of sieving and air flow to screen the flour.

The feeding material uses the vibration of the feeding device to make the material cover the entire screen width. Relying on the vibration of the screen body, the material is moving forward and layered through the screen surface and distributed on the three-layer screen. Under the combined action of vibration and air flow, the material is classified and layered according to the different particle size, specific gravity and suspension speed.

During the flour purifing process, the negative pressure air flow passes through the material layer, sucking out the debris of low specific gravity, the larger particles are pushed forward to the tail of the screen, the smaller particles fall through the screen, and the material passing through the screen is collected In the material conveying tank, the different materials that are sieved pass through the material conveying tank and the material discharging box, and are discharged according to the requirements of the process.
