Description

Technical Field

[0001] The utility model relates to the technical field of rice polishing, and particularly relates to a rice polishing processing device. Background Technique

[0002] Rice is the main grain product made from paddy through a series of processes. First, the paddy is cleaned to remove impurities, and then hulled to remove the husk. Next, through milling processing, the paddy becomes finished rice. Rice is rich in nutrients, accounting for about 64% of the rice, and contains various nutrients required by the human body, such as carbohydrates, proteins, and vitamins. These nutrients are crucial for human health. Especially in most parts of China, rice is one of the main staple foods, providing an important energy source for the people. Usually, at the final stage of rice processing, after shelling, a layer of bran layer often remains on the surface of the rice. To improve the taste and appearance of the rice, it needs to be polished. Polished rice removes the outer skin on the surface of the rice grains through mechanical methods, making it smoother and brighter. This not only improves the appearance quality of the rice, making it look cleaner and more attractive, but also improves the taste when eating, making the cooked rice softer and more delicate. Therefore, polishing is not only for aesthetics but also to improve the overall quality and market competitiveness of rice.

Next, place the polishing barrel 903 as a whole above the fixed disk 905, and assemble the polishing roller 902 and the second motor 901. Then, place the screening mechanism 11 above the driving wheel 5 and place the driving limit groove 1101 corresponding to the driving wheel 5. Then, start the first motor 2 to drive the transmission shaft 3 inside the limit block 4 to rotate, so that the driving wheel 5 drives the screening mechanism 11 to rotate. Finally, turn on the second motor 901, invert the rice to be polished into the polishing barrel 903 for polishing. The polished rice falls from below the polishing barrel 903, slides along the hopper 1002 into the material receiving inlet 1102, and after being filtered by the first filter screen 1103 and the second filter screen 1105, the rice with larger grains is obtained and produced from the discharge port 1106.
