Rice dedusting device and rice dedusting process

Abstract

The invention discloses a rice dust removing device. The rice dust removing device comprises an upper cylinder and a lower cylinder; the upper cylinder is fixedly connected to the top of the lower cylinder; a rice scattering disc is arranged on the upper cylinder; a rice inlet hole is formed in the rice scattering disc; a mesh-shaped stop rod disc is fixedly connected into the rice inlet hole; water spraying pipes are peripherally distributed on the upper cylinder, and are connected with atomizing nozzles towards the inner side of the upper cylinder; air inlet holes are uniformly distributed in the axial direction of the lower cylinder; a water sucking cylinder is fixedly connected into the lower cylinder; spiral blades are arranged on the outer side wall of the water sucking cylinder; water sucking holes are uniformly distributed in the axial direction of the water sucking cylinder; and the water sucking cylinder is filled with water sucking materials. The invention further discloses a rice dust removing process; and the rice dust removing process comprises the steps of: (A) rice feeding; (B) rice scattering; (C) dust removal through water spraying; and (D) water and dust suction. The device directly uses atomized water for being matched with the water sucking cylinder to remove dust on the surface of rice; water can cool the rice, and can remove the dust, so that the dust removing effect is guaranteed, and the rice particle quality is guaranteed; and meanwhile, the process steps are simplified, so that the dust removing efficiency is improved.

Description

technical field [0001] The invention relates to a dust removal device and a dust removal process, in particular to a rice dust removal device and a rice dust removal processing technology. Background technique [0002] Rice dedusting is a step that needs to be carried out after finishing the rice. Generally, the common rice dedusting device is a centrifugal dust collector, which consists of an inner cylinder, an outer cylinder, a conical cylinder, an air inlet, and an ash discharge port. The inner and outer cylinders and the ash discharge port are located on the same axis; the inner cylinder is evenly distributed with dust discharge holes that rice grains cannot pass through. Spiral rotating at high speed. During the rotation, the dust particles are thrown to the inner wall of the outer cylinder under the action of a large centrifugal force and collide with the wall surface, friction and the speed gradually decreases to zero, and then fall to the cone part along the cylinde...

AI Technical Summary

Problems solved by technology

In step 4 above, since there is a relatively large space in the inner cylinder, when the inner cylinder rotates, the rice in the inner cylinder cannot be evenly distributed in the inner cylinder, so it is necessary to carry out a relative Only after a long time of dust removal can a better dust removal effect be achieved. After the dust is discharged, it is necessary to discharge the clean rice, and then add the rice with dust, so that the inner cylinder cannot continuously remove dust, which affects the work. efficiency
