[0002] The rice color sorter is a machine that uses photoelectric technology to automatically sort out the different-colored particles in rice according to the difference in the optical properties of rice, so as to improve the quality of rice and remove impurities. Compared with manual selection, it saves labor, time, high efficiency, low processing cost, and improves the quality, economic and social benefits of the selected products. It includes a multifunctional rice color sorter, also known as a double-layer rice color sorter. The traditional rice color sorter uses a conveyor belt to transport rice, and uses gravity to discharge the different-colored particles and impurities with high-pressure airflow during the falling process. Although this operation method is commonly used, it also has some defects and problems: during the falling process of the conveyor belt, if the rice particles are unevenly distributed, some areas may be too dense, making it difficult for optical detection to accurately identify different-colored particles, which may reduce the accuracy and efficiency of the color sorter. And the discharge of the different-colored particles and impurities by the airflow will also cause the discharge of good rice particles. In view of this, the existing problems are studied and improved, and a double-layer rice color sorter is provided to solve the current problems, aiming to achieve the purpose of solving the problems and improving the practical value through this technology.
