Rice dust removal device

Abstract

The invention discloses a rice dedusting device, which comprises an outer cylinder, a rice bin, a sponge cover, a net bag, a blocking ball, a shunt net, a net plug, a sponge ball, an air ring, a rice box and a frame; the sponge cover, the net bag and the net plug The cylinder is divided into a primary dust removal bin and a secondary dust removal bin; the net bag is funnel-shaped with a leak at the lower end; the plugging ball is set in the primary dust removal bin; In the secondary dust removal bin; the wind ring is a hollow ring structure, located at the lower end of the net plug. The beneficial effects of the present invention are: the contact between the rice and the sponge ball or the sponge cover is not due to centrifugal force, but the wind force generated by the wind ring in the opposite direction to the falling direction of the rice, which can effectively blow away the dust carried on the rice, It has the effect of dedusting and will not damage the rice at the same time. This dedusting method does not need to wash the rice with water, but uses airflow to impact the rice, which will not cause the loss of rice nutrition.

Description

technical field [0001] The invention relates to the technical field of rice cleaning treatment, in particular to a rice dust removal device. Background technique [0002] Rice dedusting is a step that needs to be carried out after the rice has been refined. There are generally two kinds of existing rice dust removal methods, one is centrifugal dust removal, and the other is water washing dust removal; the centrifugal dust removal method is usually to put rice into a cylinder, and a brush is arranged in the cylinder, and the rotating circle The rice rubs against the inner wall of the cylinder and the brush, and the dust is cleaned, but under the action of centrifugal force, when the rice hits the inner wall of the cylinder, the rice is easily broken, and when the rice rubs against the inner wall of the cylinder at high speed, it is easy to wear the outer layer of rice, resulting in nutrition Lost, the rice grains are reduced, and the inner wall of the cylinder is difficult t...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the problem that the existing rice dedusting device easily causes rice nutrient loss and rice is easily broken, and provides a rice dedusting device with good dust removal effect, no damage to rice, and no nutrient loss
