Abstract

The invention provides a rice machining process which is finished by adopting thirteen processes of unhulled rice sieving, drying, stone removing, magnetic separation, rice hulling, husked rice separation, thickness grading, rice milling, white rice grading, color sorting, polishing, white rice grading and finished product packing. Impurities are removed by sieving, rice yield can be increased in the subsequent machining by drying, the rice quality is improved by grading for multiple times, the machining process has no pollution, a low-temperature light-rubbing rice milling mode is adopted, the rice crushing ratio is reduced and the economical benefits are improved.

[0019] Example 1

[0020] The invention provides a rice processing technological process, which adopts rice screening, drying, stone removal, magnetic separation, rice husking, grain separation, thickness grading, rice milling, white rice grading, color sorting, polishing, white rice grading, Thirteen technological processes of finished product packaging complete its processing technology;

[0021] Rice screening: use a vibrating screen to preliminarily screen the raw grain to remove debris;

[0022] Drying: Dry the rice after preliminary screening, and then pass the drying machine through the conveying equipment;

[0023] Stone removing: transport the dried rice to the stone removing machine to remove the stones in the rice;

[0024] Magnetic separation: The rice after stone removal passes through the permanent magnet drum of the magnetic separator to face the rice, which effectively removes possible metal substances in the rice and ensures the quality of rice;

[0025] Rice hulling: the magnetically separated rice is automatically transported to the hulling machine for hulling treatment. The present invention adopts the rubber roller hulling machine, which has good hulling effect, smooth brown rice surface, less broken rice, and improved yield of finished products;

[0026] Rough separation: The cleaned brown rice is automatically transported to the gravity Rough Separator for Rough Separation. The difference in specific gravity, particle size and surface friction coefficient between the Rough and Rough is used by the action of the working plate with two-way tilt and reciprocating motion. , Separate pure brown rice;

[0027] Thickness classification: the pure brown rice is separated and screened by a thickness classifier to select broken grains and immature grains;

[0028] Rice milling: After the thickness of the graded rice is cooled and stored, the stored rice is connected in series with six horizontal rice mills and gently rubbed at low temperature. After cooling and storage, the skin and aleurone layers of the rice are Easily wipe off and increase the whole rice rate;

[0029] White rice grading: pass the polished rice through a white rice grading sieve for a rice grading, and extract the rice that exceeds the requirements for grading;

[0030] Color sorting: The graded rice is automatically transported to the color sorter for color sorting, removing yellow rice and unqualified rice to improve the quality of rice;

[0031] Polishing: The color-selected rice is automatically transported to the polishing machine for polishing process. The polishing machine is equipped with a flow sensor to control the flow of rice to achieve the best polishing effect;

[0032] White rice grading: pass the polished rice through a white rice grading sieve for secondary rice grading, and extract the rice that exceeds the requirements for grading, so that the quality of the rice is further improved;

[0033] Finished product packaging: the above-mentioned different types of rice are packaged separately, and then sent to the air-conditioned constant-temperature finished product warehouse for storage, and the different types are stored separately.

[0034] The invention removes impurities through screening, can increase the rice yield rate in subsequent processing after drying, and can improve the quality of rice after multiple classifications. The processing process of the invention has no pollution, adopts a low-temperature light rubbing rice milling mode, and reduces the rate of broken rice. ,Improve economic efficiency.
