Novel husked rice color sorting separation process with high quality and high benefit

Abstract

The invention relates to the technical field of color sorting separation, in particular to a novel husked rice color sorting separation process with high quality and high benefit. The process comprises the following steps: S1, feeding: providing clean rice which contain impurities and meet processing requirements; S2, rice husking: conducting husking treatment on the clean rice through a rice husker; S3, screening: screening the husked rice through a plane rotary screen, so that the husked grains are separated from rice husk and dust; S4, color sorting: sorting out the grains with different colors through a color sorter according to the optical characteristic difference of the grains, wherein the color sorter has multiple color sorting processes; and S5, husked rice separation: collecting the husked rice sorted by the color sorter to obtain clean husked rice. Impurities in the clean rice can be rapidly separated, and the separated valuable materials are independently selected, so that the economic benefit is increased; and meanwhile, the problems that the rice is polluted after the black ear grains enter the rice milling process, the color of the rice is influenced, the content of mould and toxin is increased, and the food safety is directly influenced can be solved.

Description

technical field [0001] The invention relates to the technical field of color sorting and separation, in particular to a novel high-quality and high-efficiency color sorting and separating process for paddy rice. Background technique [0002] In the modern rice processing technology, the cleaned and stone-removed rice has to be hulled by a huller, and the hulling rate is normally between 85% and 95%. The mixture of brown rice and paddy after husking needs to be separated by special equipment. The traditional paddy separation equipment uses a gravity paddy separator; it only separates paddy from brown rice; it cannot remove other impurities in the paddy. If other impurities need to be removed, then Multiple removal processes are required. [0003] Secondly, rice smut granules contain harmful substances such as molds and toxins, which are difficult to clean up by conventional processes. After smut granules enter the rice milling process, they will pollute the rice, which will ...
