Background

In the production process of arrowroot, fine sand contained in arrowroot is usually removed by a sand removal cyclone, the separation principle of the sand removal cyclone is that materials to be separated enter a cylinder part of the sand removal cyclone at a certain speed in a tangential direction to do circular rotation motion, and materials with different specific gravities obtain different centrifugal forces. The fine sand with low specific gravity obtains larger centrifugal force to be thrown to the outer layer of the circular motion to perform outer rotational flow, and the arrowroot milk with higher specific gravity is positioned in the inner layer of the circular motion to form inner rotational flow. The materials move downwards in a spiral shape and spirally descend to a bottom flow port along the inner wall of a conical barrel on the cyclone. The arrowroot milk rotating and descending in the inner layer of the circular motion is blocked by the underflow opening and moves upwards in the same rotating direction to be discharged from the core pipe at the top of the cyclone. The existing desanding cyclone has low separation efficiency and poor effect, and the degritted arrowroot powder still contains fine sand, which seriously influences the quality of the arrowroot powder.
