"Food is the God of the people" China has been a traditional agricultural country since ancient times, with deep feelings for land and grain. Food is hard won. Most of the rice in China comes from the production of individual farmers, with many varieties; Poor harvesting and drying conditions, and more impurities in raw grains; It brings great difficulty to rice processing, and solving this problem becomes the top priority. There are so many instruments for rice processing and sorting on the market that a high-quality rice color sorter becomes the main choice to improve work efficiency.

The rice enters the machine from the top hopper, and the selected rice falls down along the feeding and distribution trough through the vibration of the feeding device (vibrator). The rice passes through the upper end of the rice track, slides down the rice track, enters the sorting box, enters the sorting box, and passes between the image processing sensor CCD and the background device,

The Korean rice color sorter receives the synthetic light signal from the selected rice under the effect of the light source, so that the system generates the output signal, amplifies and transmits it to the FPGA+ARM computing processing system, and then the control system sends instructions to drive the action of the jet solenoid valve, blowing the heterochromatic particles into the waste cavity of the discharge hopper to flow away. The good selected rice will continue to fall into the finished product cavity of the receiving hopper and flow out, so that the selected rice can reach the purpose of selection.

The moisture content of rice processing should be controlled at 14.5% - 15%. For rice stored at low temperature for a long time, the moisture content should be measured before processing. The moisture content of brown rice should be lower than 14%. The brown rice conditioner should be used as far as possible for conditioning treatment before processing; After conditioning, the color of processed rice was obviously improved, the glossiness was increased, the finished product rate was increased by 1%, and the broken rice rate was reduced by 0.5%; At the same time, the moisture content of rice after conditioning increased, and the working current during processing decreased by 10%, saving the unit energy consumption of processing.

The improvement of rice color and the reduction of broken rice rate have increased the selling price of rice to a certain extent, while the increase of finished product rate will increase the quantity of rice processed from rice, and the appropriate increase of rice moisture will improve the eating quality of rice. It can be seen from the above that proper humidification and conditioning of rice before processing will significantly improve the processing quality of rice, with significant economic and social benefits.
