Abstract
The invention provides a method for processing and purifying rice. The processing technology of the method is completed by thirteen technological processes as follows: unhulled rice screening, drying, stone removing, magnetic separating, rice hulling, husked rice separating, thickness grading, rice milling, white rice grading, color sorting, polishing, white rice grading and finished product packaging. According to the method for processing and purifying rice, impurities are removed through screening; after drying, the finished product rate can be increased in subsequent processing; the quality of rice can be improved through grading for multiple times; the processing course is pollution-free; and a low-temperature rice-rubbing and rice-milling mode is adopted, so that the broken rice rate is reduced, and the economic benefit is increased.
Description
Technical field
The present invention relates to a kind of rice processing technique, be specifically related to a kind of rice processing impurity-removing method.
Background technology
At present, in the processing technology of rice, raw grain is substantially based on machine receipts, peasant household can not carry out multiprocessing to grain substantially, raw grain is caused to mix, impurity is more, water content is uneven, very large difficulty is brought to rice processing, through shelling, after husk rice, the temperature of rice is higher, if directly send into polishing machine polishing, appearance sense organ can be caused not bright and clean on the low side with broken rate higher rice finished product rate, also because paddy moisture is higher, shortened shelf life, in addition the idea of consumer improves constantly rice bright and clean, the attention of mouthfeel, the rice of present single variety processing can not meet consumer demand.
Summary of the invention
The invention provides a kind ofly can reduce broken rice rate, improve whole grain rice rate, the rice of long shelf-life processing impurity-removing method.
The present invention adopts following technical scheme to realize its goal of the invention, a kind of rice processing impurity-removing method, its adopts paddy screening, oven dry, de-stone, magnetic separation, paddy rice are shelled, the rough separation of paddy, thickness classification, husk rice, rice grading, look choosing, polishing, rice grading, finished product packing 13 road technological process complete its processing technology;
Paddy screens: adopt vibratory sieve to carry out Preliminary screening impurity elimination thing to raw grain;
Dry: drying and processing is carried out to the paddy after Preliminary screening, carries out drying and processing by conveying equipment through dryer;
De-stone: the paddy after drying is delivered to stone remover, removes the stone in paddy;
Magnetic separation: the paddy after de-stone goes in the same direction through the electromagnetic drum of magnetic separator and paddy, effectively rejects the metallics that may exist in paddy, guarantees rice quality;
Paddy rice is shelled: carry out process of shelling in the paddy automatic transport after magnetic separation to green paddy machine, and what the present invention adopted is rubber roll husker, shells effective, brown rice smooth surface, and crack rice few, the finished product rate of output improves;
The rough separation of paddy: the brown rice automatic transport after clear assorted carries out the rough separation of paddy to gravity type paddy separator, utilize paddy rough between the difference of proportion, granularity and skin-friction coefficient, by means of the effect of inclined in two-way, reciprocating working plate, isolate clean brown rice;
Thickness classification: clean brown rice sub-elects broken kernel, immature kernel through thickness grading machine bolter;
Husk rice: the rice after thickness classification is entered supercooling and store, dabs light stone roller by the rice stored six horizontal rice whitening machines low temperature that is cascaded, and its cortex of rice after supercooling storage and aleurone are just wiped like a cork, improve head rice yield;
Rice grading: the rice after husk rice is carried out a rice classification by white rice grader and arranges, extracts the rice exceeding requirement and carries out grade separation;
Look selects: the rice automatic transport after classification carries out look choosing to color selector, removes glutinous millet and underproof rice, to improve the quality of rice;
Polishing: the rice automatic transport after look choosing carries out glossing to polishing machine, is provided with flow inductor in polishing machine, controls the flow of paddy, to reach best polishing effect;
Rice grading: the rice grain pattern after polishing is crossed white rice grader and carry out secondary rice classification arrangement, extract the rice exceeding requirement and carry out grade separation, the quality of rice is promoted further;
Finished product packing: packed respectively by above-mentioned different types of rice, delivers to after packaging and fills the storage of air-conditioned refrigerating chamber, separately stored respectively by variety classes.
Beneficial effect of the present invention: the present invention removes impurity by screening, a meter rate can be increased in following process after drying, the quality of rice can be improved through multiple fractionation, process of the present invention is pollution-free, adopt low temperature to dab husk rice pattern, reduce broken rice rate, increase economic efficiency.
