A dust removal device for rice processing

Abstract

The invention discloses a dust removal device for rice processing, which includes a cleaning device. The cleaning device includes a body, an auger and a rice collection frame. The body is provided with a cleaning room and a rice collection room. The cleaning room includes a first swimming lane, a second The swimming lane and the third swimming lane, the first swimming lane, the second swimming lane and the third swimming lane are arranged in order from top to bottom, the first swimming lane, the second swimming lane and the third swimming lane are connected in sequence to form an S shape, the first swimming lane, the second swimming lane and the An auger is respectively arranged in the third swimming lane, and the rice collection chamber is arranged at the end of the third swimming lane, and the bottom height of the rice collection chamber is lower than the height of the third swimming lane, and the rice collection frame is arranged in the rice collection chamber, and the rice collection frame The height of the upper edge is not higher than the height of the third swimming lane, the side and surface of the rice collection frame are provided with a plurality of screen holes, and the bottom of the third swimming lane is provided with a drain. Compared with the prior art, the invention utilizes the cleaning device to realize the cleaning of the rice, utilizes the drying device to realize the drying of the rice, and can realize the rapid dedusting of the rice.

Description

technical field [0001] The invention relates to a dust removal device, in particular to a dust removal device for rice processing. 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 cylinder wall under the action of gravity, and then It is discha...

AI Technical Summary

Problems solved by technology

[0003] The above centrifugal dust collectors in the field of rice processing have the following problems. On the one hand, due to the action of centrifugal force, the interaction between the dust and the outer cylinder wall is relatively large, and the dust is easy to adhere to and accumulate on the outer cylinder wall, making it difficult to clean. Seriously affect the dust removal effect; on the other hand, the high-speed rotation of the inner and outer cylinders can easily break the rice, resulting in a decline in the overall quality of the rice
