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.
