METHOD OF SEPARATION OF GRAIN MIXTURE IN HULLING MACHINE AND HULLING MACHINE FOR REALIZATION OF THIS METHOD Russian patent published in 2003 - IPC

FIELD: separation of grain mixtures. SUBSTANCE: proposed method includes delivery of grain mixture to intake branch pipe and then to sorting chamber, cleaning of grain from dust and partial separation of shells and germs, separation of mixture into tailings and minus fractions. Minus fraction is removed by aspiration air flow. Before separation in sorting chamber, grain mixture is separated into fractions by aspiration air flow which is formed by taking air from grain mixture flow in intake branch pipe. Hulling machine is provided with intake branch pipe, housing with sorting chamber where drum is located with sieve under it; minus fraction branch pipe, tailings branch pipe and air intake port are located under sieve. Air intake port is combined with intake branch pipe and minus fraction branch pipe is connected with aspiration passage. EFFECT: enhanced efficiency of separation. 3 cl, 2 dwg
