Abstract
Description
Technical Field
[0001] The present application relates to the technical field of rice processing equipment, and particularly relates to a vibrating sieve bran device for rice processing. Background Art
[0002] During the process of processing paddy into polished rice, the outer shell and about 10% of the total weight of the pericarp, seed coat, aleurone layer, endosperm, and embryo need to be removed. Traditional rice bran, that is, the current national standard rice bran, is mainly made from the pericarp, seed coat, aleurone layer, endosperm, and embryo. Therefore, a small amount of rice husk, a certain amount of dust, and microorganisms will be mixed in during the processing. So rice bran can only be used for feed and is the main by-product of paddy processing. If the bran screening process is not carried out, it will greatly affect the edibility. Therefore, a sieve bran device is needed to remove the rice bran in the rice to meet the taste requirements of people.
[0003] Currently, a vibrating sieve bran device for rice processing announced in the Chinese patent with the publication number CN215542660U includes a sieve bran box. A circular groove is opened at the top of the sieve bran box, and a feeding component is arranged in the circular groove. A group of fixing plates are fixedly connected to both sides of the upper end inside the sieve bran box. With the above structure, by setting the mounting plate, a sieve mesh plate is arranged between the two mounting plates, and a vibrating motor is installed on the top of the mounting plate. The rice that needs to be sieved is added into the sieve bran box through the feeding funnel in the feeding component. The rice passing through the feeding funnel will fall on the sieve mesh plate for screening. The rice bran will remain on the top of the sieve mesh plate, and the rice will pass through the mesh holes of the sieve in the sieve mesh plate and fall into the receiving box. And some rice bran with smaller particles will fall with the rice. By setting the air separation component, the rice bran with smaller particles can be blown onto the surface of the filter mesh plate for collection, so that the clean rice falls into the receiving box, greatly improving the efficiency of rice bran screening.
[0004] In actual use, it is found that the existing vibrating sieve bran device for rice processing cannot convey rice at a uniform speed during feeding, which is likely to cause the rice to accumulate on the sieve mesh, and then lead to insufficient screening of the rice during bran screening, affecting the screening effect. Therefore, we propose a vibrating sieve bran device for rice processing to solve the above problems. Utility Model Content
