Description
Technical Field
The utility model relates to a high-efficiency air knife winnowing device which is applied to the field of grain processing.
Background
In the rice processing process, materials are required to be transferred from one device to the next device through a lifter, a chute and the like, and dust can often appear in the process or dust generated after the processing of the previous device. For example, after the rice mill is processed, the surface of the discharged rice grains is often attached with bran powder which is not cleaned by a machine, and the bran powder is not cleaned in time, so that the processing effect of the next processing procedure is affected, and a chute is easily blocked due to long-term accumulation, so that the production efficiency and the product quality are affected. In the traditional mode, three through holes are usually selected on a chute, and the material is simply winnowed by an air suction pipe, so that the efficiency is not high although the mode has a certain effect; particularly, when high yield is encountered, the thickness of the material layer in the chute is not ideal in winnowing effect; in addition, due to the limitation of the installation space, the wind separation pipeline is not necessarily well bonded in many cases. Therefore, there is a need for an efficient air separation device that is easily attachable to a chute or to a discharge port of a device.
