The color sorting camera 9 can transmit images to the controller, and the controller can control the opening of the solenoid valve in the corresponding branch air pipe 12 according to the image;

[0021] The rice is fed through the feed port 2 and falls onto the primary color sorting mechanism 3, where the defective rice and some qualified rice are blown onto the conveyor belt 4. The power of the conveyor roller 5 is turned on, and the conveyor roller 5 drives the conveyor belt 4 to move. The conveyor belt 4 drives the rice through the lower part of the guide plate 7, which guides the rice into the hemispherical groove 6 on the conveyor belt 4, so that the hemispherical groove 6 contains a single grain of rice. The rice passes through the lower part of the color sorting camera 9, which transmits the image to the controller. The controller identifies the rice grains in the hemispherical groove 6. If there are defective rice grains, the controller controls the solenoid valve in the corresponding branch air pipe 12 to open, and the air intake system exhausts air into the branch air pipe 12 with the opened solenoid valve through the air intake pipe 13.

[0023] After the rice falls, it enters the inclined trough 31 and falls down. The color sorting camera 9 shoots the rice, the air intake system injects air through the second air intake pipe 34, and the controller controls the branch air pipe 33 to open, thus completing one color sorting.

The inferior quality rice is blown over the double-sided slope plate 15 and discharged through the lower part of the other side.
