Technical Field

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

[0002] Rice, also known as paddy rice, is a food made from paddy through processes such as cleaning, hulling, milling, and finishing. Rice processing is the core link in the grain industry chain, using modern technology to transform paddy into safe and high-quality finished rice. Rice contains about 75% carbohydrates, 7%-8% protein, 1.3%-1.8% fat, and is also rich in B vitamins.

[0003] Regarding the above and existing related technologies: During rice processing, rice contains broken grains and underdeveloped grains. To ensure quality, a screening machine is needed to screen the rice. Since the screen has holes, the size of the broken grains may fit the holes, causing them to get stuck. Traditional screening machines lack a dedicated cleaning mechanism, which can lead to inconvenience and time-consuming cleaning. Therefore, a screening machine for processing premium rice is proposed to address these issues. Utility Model Content
