Description

Technical Field

[0001] The invention relates to the technical field of rice bran processing, in particular to a rice bran and chaff separator. Background Art

[0002] Rice bran is primarily made from the pericarp, seed coat, outer endosperm, aleurone layer, and germ. During processing, a small amount of rice husk, dust, and microorganisms are mixed in. Therefore, it can only be used as feed, being a major byproduct of rice processing. Rice bran is rich in various nutrients and bioactive substances. Modern food processing precision milling technology is used to separate harmful components in rice bran, such as the husk, pericarp, seed coat, dust, and microorganisms, from beneficial components, such as the germ, aleurone layer, and outer endosperm. This separation process allows rice bran to be classified into feed-grade and food-grade components. Food-grade rice bran accounts for approximately 80% of the total weight and over 90% of the nutrients. Because food-grade rice bran, while only 6% of the rice grain's weight, contains approximately 60% of its nutrients and is the byproduct of the rice milling process, it is also known as rice treasure or rice meal. With increasing awareness and technological advancements, rice bran has become a valuable resource for food processing. Rice bran is widely used in feed and as a huge renewable resource, it will have a good development prospect in the future. If it is used properly, it will produce immeasurable economic benefits.

[0003] In the prior art, rice bran separation adopts an application publication number CN113262837A invention that discloses an intelligent flexible bran separator, which includes a frame, and a rubbing system, an air inlet system, a feed port, a discharge system, a motor, a bran discharge channel, and a casing arranged on the frame. The rubbing system includes a rotor, a rotary screening system, and a passive pulley. The rotor is a rotating shaft, and a passive pulley is fixedly installed at the tail of the rotating shaft. The passive pulley is connected to the motor through a belt, and the rotor is driven to rotate by the motor. The rotary screening system is a cylindrical tube structure, which is sleeved on the outside of the rotor and fixedly mounted on the slewing support of the frame. It is driven by a special reduction motor and combined with the main shaft assembly to have a same-direction difference. The rotor and the rotary screening system are both equipped with polishing rods, which greatly improve the polishing efficiency during operation. During the polishing operation, air is supplied to the space between the rotor and the rotary screening system, which reduces the friction temperature during bran and bran separation and ensures separation. However, this separation method causes rice bran to adhere to the inner wall of the drum after long-term use, resulting in a decrease in screening effect, thereby affecting the quality of subsequent products.
