Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of rice bran production and processing, in particular to a rice bran impurity screening device. BACKGROUND

[0002] Rice bran is rich in nutrients and physiological active substances, including protein, fat, sugar, moisture, vitamins, plant alcohol, dietary fiber, amino acids and minerals. Rice bran is the main by-product of rice processing, mainly made of pericarp, seed coat, outer endosperm, aleurone layer and embryo. In the processing process, a small amount of rice hull and a certain amount of dust, microorganisms and other impurities will be mixed into the rice bran. In order to improve product quality and protect food safety, impurities in rice bran need to be screened to remove impurities in rice bran. When screening impurities in rice bran, screening devices are needed.

[0003] Common rice bran impurity screening devices are usually composed of a shell, a support structure, a feed inlet, a conveying mechanism, a screening mechanism, an impurity outlet and a collecting device. The conveying mechanism conveys rice bran into the shell through the feed inlet, the support structure provides stable support for the shell, the screening mechanism screens rice bran, and the impurities are conveyed to the inside of the collecting device for storage through the impurity outlet.

[0004] Traditional rice bran impurity screening devices contain iron impurities due to processing equipment and other reasons. The iron impurities are usually heavy in individual and cannot be screened by the fan. The iron impurities fall on the screen, which not only causes the screen to be blocked during use, but also damages the screen when it falls, thereby affecting the subsequent screening operation and screening effect of rice bran impurities. To solve the above problems, some rice bran impurity screening devices add magnetic materials such as magnets inside the device. When rice bran passes through the magnetic material, the iron impurities in the rice bran impurities are adsorbed, so that the fan and the screen can normally screen the rice bran impurities. However, this method has limitations because the magnetic material can only adsorb a limited amount of iron impurities and is located inside the device. The iron impurities on the magnetic material cannot be cleaned until the device is disassembled, which not only makes it difficult to clean the iron impurities on the magnetic material, but also affects the subsequent screening of rice bran impurities. Therefore, a rice bran impurity screening device is proposed. UTILITY MODEL CONTENTS
