Description

Technical Field

[0001] This utility model relates to the field of rice processing screening technology, specifically a screening device for fine rice processing. Background Technology

[0002] Rice is a finished product made from paddy through cleaning, hulling, milling, and finishing processes. The germ and aleurone layer of paddy contain nearly 64% of the rice's nutrients and more than 90% of the nutrients required by the human body. Its main health benefits include replenishing qi and strengthening the spleen and stomach. After cleaning and hulling, the resulting rice grains are white and coarse. To enhance its taste and color, it needs to be refined through milling, polishing, and screening to produce qualified organic rice. To complete these steps, specialized equipment for rice refining is now widely used.

[0003] For example, Chinese patent CN220611221U discloses a screening device for rice refining. This component includes a tank with a feed hopper fixedly connected to its top. A support frame is installed inside the tank. This invention comprises a support frame, a screen, a vibrating motor, a limiting hoop, and support blocks. The support frame, made of aluminum alloy, supports the screen, which is made of mesh with several 4mm diameter holes to allow broken rice particles and dust to fall through. The limiting hoop is annular, and the screen is welded to its inner wall to form an integral structure, improving its stability. Six support blocks are symmetrically welded to the inner wall of the tank to support the limiting hoop. The support blocks are tilted at a 10-degree angle, allowing the rice to roll under its own weight, thus improving screening efficiency. Activating the vibrating motor causes the support frame and screen to vibrate, preventing screen blockage and further improving rice screening efficiency.

[0004] However, in actual application, after the rice is screened, a large amount of rice ash and impurities are generated during the rice processing, resulting in a large amount of dust in some of the screened rice, which affects the quality of the rice after screening.

[0005] Therefore, how to design a screening device for rice refining has become a problem that we need to solve. Utility Model Content

[0006] (a) Technical problems to be solved

[0023] (III) Beneficial Effects

[0024] This utility model provides a screening device for rice refining, which has the following beneficial effects:

[0025] By setting up a placement box, when workers put the rice to be sieved into the placement box, the rice inside the two fixed frames can be sieved through the screens. When a rotating component drives a rotating rod to rotate, the rotating rod can drive the fan blades to rotate, so that the fan blades can extract the dust generated during the sieving process inside the placement box. This reduces the amount of residual dust in the rice after sieving, thereby improving the quality of the sieved rice. At the same time, the rotating rod can also drive a striking component to rotate, so that the striking component can strike the screen and make the screen vibrate, thereby preventing rice grains from getting stuck in the screen's pores and improving the sieving efficiency.
