Description

Technical Field

[0001] The utility model relates to the technical field of rice processing, in particular to a rice processing bran screening device. Background Art

[0002] Rice is the finished product made after processes such as cleaning, hulling, milling, and finished product finishing of paddy. Rice contains nearly 64% of the nutrients in rice and more than 90% of the nutrients required by the human body. At the same time, it is the main food for people in most parts of China. Bran, a Chinese character, originally refers to the outer shell of grains, a part of the whole grain, belonging to the outer layer of the seed. Rice containing bran is brown rice, while rice without bran is polished rice. Bran is the inedible part of the whole grain, which includes the exocarp and mesocarp of the whole grain.

[0003] The published patent No. CN219631954 discloses a rice processing bran screening device, including a first support leg. A second support block is fixedly installed on the side surface of the first support leg. A blower is fixedly installed on the surface of the second support block. A rotating shaft is installed through the inside of the blower. The tail of the rotating shaft is in contact with a bearing. The surface of the bearing is fixedly connected to the second support block. A second support leg is fixedly installed on the surface of the second support block. The top of the second support leg is in contact with a third support block. A feed bin is in contact with the surface of the third support block. When the utility model is in use, by installing a blower on the side surface of the first support leg, the motor can drive the square fan blades to blow air into the bran blowing box. By fixedly connecting the top of the bran blowing box to the feed bin, the rice to be processed can enter its interior evenly for air separation. At the same time, by installing multiple round rods on the side surface of the feed bin, impurities in the rice can be filtered, making the work smooth. However, the prior art still has drawbacks:

[0004] Although the prior art can filter out larger impurities when introducing the paddy to be screened through the installation of multiple round rods, thereby reducing the impact of blockage during the working process on the working progress, when the paddy filtered by the round rods falls into the feeding port through the baffle and then into the bran screening box through the feeding port, the falling quantity of the paddy cannot be accurately controlled. When a large amount of paddy falls into the interior of the bran screening box simultaneously, it is difficult for the bran screening box to completely and effectively separate the rice and the bran, thus affecting the efficiency and quality of bran screening.
