        Why need clean the paddy when processing the rice ?
        Sep 30, 2021

        Why need clean the paddy when processing the rice ? In the process of rice milling ,  it is inevitable that a certain amount of various impurities will be mixed with rice due to harvesting, threshing, storage, transportation and other reasons.

         

        1. The harmfulness of impurities in the rice processing

        Easy to damage processing equipment, increase maintenance costs;Influence and reduce the process effect and production capacity of equipment;Polluting the environment and affecting the health of workers.

         

        2. Classification of impurities

        Miscellaneous: impurities larger than rice, i. e., retained on ф 5.0 sieve.

        Small impurity: impurities smaller than rice, that is, through the ф 2.0 sieve under impurities.

        Light impurity: Impurities separated by air and collected by dust collector.

        Metal impurity: mainly ferromagnetic impurity

        Basic method of impurity cleaning

        1, Air separation method: the use of grain and impurities suspension speed difference, with the help of air impurities or grading method.(Vertical suction duct) .

        2, Screening method: the use of screening material particle size difference, with the sieve separation of impurities, or the raw grain classification method.(Rotary cleaning screen) .

        3. Specific gravity separation method: the method of sorting by using the difference of the specific gravity of rice and impurities.(Specific gravity stone removing machine) .

        4, Magnetic separation method: the use of magnetic force to remove magnetic metal impurities in rice.(Magnetic separator) .
