SEED-WINNOWING MACHINE FOR SEPARATING HULLING MIXTURE OF OIL SEEDS Russian patent published in 2017 - IPC C11B1/02 

FIELD: agriculture.

SUBSTANCE: machine is proposed, consisting of a sifter, which has an output box with branch pipes for removing hulling mixture particles calibrated by linear sizes, with a pre-sifter, inside which there are layers of sieves with pallets, and an aspiration device for separating air-entrained particles with an airflow. Each branch pipe for removing hulling mixture particles calibrated by linear sizes is docked with a corresponding branch pipe of the intake chamber of the aspiration device, which is a vertical pneumatic separating channel. Each sieve in each receiving chamber is equipped with a device for its movement along its length, the diameter of the openings of these sieves being not less than the diameter of the openings of the corresponding sieves in the sifter.

EFFECT: increasing the efficiency of the seed-winnowing machine due to excluding the formation of the winnowing residue fraction.
