Description

Technical Field

[0001] This utility model relates to the field of rice sorting technology, specifically a rice sorting device with a continuous feeding mechanism. Background Technology

[0002] Rice is a finished product made from paddy through cleaning, hulling, milling, and finishing processes. Before it can be consumed, rice needs to undergo multiple processing steps to enter the market. Paddy is processed through a hulling machine to obtain brown rice. The brown rice is then milled by a rice milling machine to separate the bran and endosperm from the surface of the brown rice, improving its quality. After that, the rice is polished by a polishing machine to make its surface more shiny. Before processing, the rice needs to be fed.

[0003] However, currently, rice sorting is done manually, by carrying the rice to the sorting device. This method increases labor costs and significantly reduces work efficiency. Therefore, we propose a rice sorting device with a continuous feeding mechanism. Utility Model Content
