Description

A kind of rice fine-processing technique
Technical field
The present invention relates to technical field of agricultural product process, specially a kind of rice fine-processing technique.
Background technology
Oryza sativa L., as the first generalized grain kind of China, has widest consumer objects, huge development potentiality and wide Wealthy market, researchs and develops very high social benefit and economic worth to it.In general, traditional rice work flow base The operations such as cleaning, rice huller paddy, the rough separation of paddy, husk rice, rice refining, its processing method carrying with living standards of the people are all included on basis Height constantly develops and assumes mechanization trend.
Paddy processing is become rice by existing mechanized equipment, all using the processing mode of one continuous line, that is, using The production line of dragon, continuously once completes from Oryza glutinosa to rice finished product, although this traditional processing technique efficiency is higher, It is in operations such as husk rice, polishing, classifications, the continuous prodution of mechanization can greatly increase big because processing technique program is numerous and diverse The cost of rice processing enterprise, also results in that its rice milling yield is high, fineness is bad simultaneously, and in process, can because Equipment humidity controls the broken rice rate of the not good rice leading to process high.
Content of the invention
Technical problem solved by the invention is to provide a kind of rice fine-processing technique, to solve in above-mentioned technical background Defect.
Technical problem solved by the invention employs the following technical solutions to realize:
A kind of rice fine-processing technique, specifically includes following operating procedure:
1st, Oryza glutinosa is put into successively cylinder receiving sieve and vibrosieve, respectively remove Oryza glutinosa in miscellaneous greatly and in miscellaneous, little miscellaneous, then Oryza glutinosa after roguing is sent into stone remover hopper, removes stone shoulder to shoulder through stone remover, then will remove the Oryza glutinosa after stone through magnetic separation Metallicses that may be present in Oryza glutinosa rejected by machine.
2nd, the edible alkali solution accounting for water quality 5% is allocated uniformly and is heated to 50 ~ 60 DEG C, then the Oryza glutinosa after magnetic separation adds Enter and soak half an hour, then rinsed 10 minutes with 40 ~ 50 DEG C of flowing warm water, then Oryza glutinosa is spread out and dry or with cold Wind air-dries to water content 32 ~ 35%, then puts into hulling machine and carries out process of shelling, and makes brown rice and rice under blower fan suction Shell carries out crude separation.
3rd, the brown rice automatic transport after operating crude separation carries out the rough separation of paddy to grain separating machine, isolates only rough Rice, adopts thickness grading machine to remove immaturity grain and broken kernel successively, and it is classified, using air-cooler, brown rice is aqueous Amount is dried to 23 ~ 26%, and it is carried out out with rough and pearling, then, by ascorbic acid:Edible alkali:Water=2:50:1000 ratio Prepare soak, will open after the grain of rice after rough and pearling soaks 10 minutes with soak, washed down with 40 ~ 50 DEG C of flowing warm water, Then natural air drying or cold wind air-dry to water content 18% ~ 22%.
4th, by dried rice through going out rice whitening machine go out white after by divulge information cloth bag be cooled to after room temperature send into throwing Ray machine, arranges relevant parameter according to grain of rice size grade, weeds out the debris being attached on rice, make rice sparkling and crystal-clear bright, table The Starch formation gelatinous layer in face, then respectively by the color selector of relative set, sorts out the heterochromatic granule in rice, will throw Light, it is delivered to rice classifying screen again and carries out reclassification, separate special one meter, general rice, big broken rice and small brokens, then distinguish It is delivered to corresponding rice barn to carry out packing.
In the present invention, the natural air drying of the grain of rice is carried out in louvered gravity-flow ventilation storehouse, can effectively improve it and air-dry effect Rate, also can be sterilized in louvered gravity-flow ventilation lab setting uviol lamp simultaneously.
In the present invention, described soak can be circulated use, and every hectolitre soak can carry out 4 ~ 5 immersion operations.
Beneficial effect:Processing technique program of the present invention is simple, and rice milling yield is high, shells in Oryza glutinosa and rolles over a meter operation, all Rice is polished simultaneously, is classified intensification rice in operation and carries out cooling and enter back into next section adding by the strict water content controlling Oryza glutinosa Work operation, can effectively improve polished rice rate, reduce broken rice rate, and maximum composition preserves the nutrient substance in grain of rice epidermal area.
Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that the present invention realizes are easy to understand, tie below Close specific embodiment, the present invention is expanded on further.
Embodiment one:
Collect early rice, Oryza glutinosa is put into successively miscellaneous greatly in cylinder receiving sieve removing Oryza glutinosa, then pass through three-level vibrosieve respectively Dispel miscellaneous and little miscellaneous in Oryza glutinosa, then the Oryza glutinosa after roguing sent into stone remover hopper, remove stone shoulder to shoulder through stone remover, Then the Oryza glutinosa after stone will be gone to remove metallicses present in Oryza glutinosa through magnet separator magnetic despecking.
Add in the water of 1000 mass parts with the edible alkali of 5 mass parts, allotment uniformly and is heated to 50 DEG C, then by magnetic separation Oryza glutinosa afterwards is added to the water immersion half an hour, is rinsed 10 minutes with 50 DEG C of flowing warm water, after the completion of flushing after the completion of immersion Oryza glutinosa is spread out in louvered gravity-flow ventilation storehouse and cold wind air-dries to water content 30%, then put into hulling machine and carry out place of shelling Reason, and make brown rice and rice husk carry out crude separation under blower fan suction.
Brown rice automatic transport after crude separation is operated carries out the rough separation of paddy to grain separating machine, isolates net brown rice, Adopt thickness grading machine to remove immaturity grain and broken kernel successively, and it is classified, using air-cooler by brown rice water content It is dried to 25%, and it is carried out out with rough and pearling, then, by ascorbic acid:Edible alkali:Water=2:50:1000 proportions Soak, will open after the grain of rice after rough and pearling soaks 10 minutes with soak, is washed down with 45 DEG C of flowing warm water, then natural Air-dry or cold wind air-dries to water content 20%.
