Korean rice color sorter mainly selects moldy rice, black spot rice, yellow rice, small stones, heterochromatic particles and other impurities in rice according to the color difference of rice, so as to obtain high-quality rice and improve the quality and quality of rice. The rice color selected by the rice color sorter has the same quality, crystal clear and full, and is a good helper for rice processing.

The development of color sorters has brought about a turnaround situation for manufacturers, not only in the grain industry, but also in all walks of life, such as rice, miscellaneous grains, tea, etc. plastics, ores, jewelry, metals, seafood, etc. can be met to achieve industry coverage, and color sorters have gradually developed abroad, not only for national sales, but also exported to the United States, Brazil, India and other countries and regions, with an annual output value of more than 100 million yuan. The feeding system is mainly composed of three parts, hopper, vibrator and chute.

Among them, the main components are the selection of chutes. At present, most of the chute color separators on the market still use hard aluminum alloy materials to make chutes, so as to ensure that the wear of chutes is within a controllable range, reduce the replacement frequency of chutes, and improve the service life of color separators, which has achieved the goal of improving production efficiency. Domestic color separators have developed special-purpose and multi-functional color separators for different product needs of customers. At present, it can meet the color separation requirements of more than 7000 products, such as rice, tea, beans, medicinal materials, seeds, shrimp skins, nuts, various dry goods, plastics, jewelry, ores and other special materials.

There should be no stones, metals and other substances in the rice entering the color separator, which requires that reasonable cylinder primary cleaning screen, plane rotary screen, stone remover, dust collector, self balancing vibrating screen and magnetic separator should be installed in the primary cleaning section to remove as many impurities as possible, reduce the content of different color particles, reduce the working pressure of the color separator, give play to the primary cleaning function, and improve the efficiency of color separation.

White rice must be graded before the selection of big rice. After rice hulling, rice milling, polishing, grain roughness separation and impact during mechanical transportation, some heterochromatic grains that have become broken grains mainly include immature grains, moldy grains, yellow grains, etc. these grains have low tensile and compressive strength, higher crushing rate than normal, and a high proportion in medium and small crushing. Through classification, the workload of the color separator can be greatly reduced.
