Abstract
This utility model discloses a device for removing powder and microparticles from finished rice, belonging to the field of rice impurity removal technology. The utility model includes a feeding assembly, a chamfered box, a vibrating filter layer, and a support base. The chamfered box includes a box body with a dust suction port on one side. The vibrating filter layer includes partitions and a filter screen structure. Two partitions are provided, forming a cavity between them. The filter screen structure is slidably disposed within the cavity. A groove is provided at the rear of one partition and at the front of the other partition. The rear groove matches the guide opening of the box body. The vibrating filter layer is mounted on a support base. Through the structural design of the chamfered box, combined with the feeding assembly consisting of a spiral feeder and a trapezoidal funnel, the negative pressure airflow generated by the dust suction port of the chamfered box can accurately adsorb the powder raised during vibration, avoiding the problem of incomplete removal of light powder by traditional air-separation equipment. This ensures that the rice is evenly distributed on the filter screen structure, preventing localized accumulation that could lead to screen wear or clogging.
