Rotatively oscillating separator

Abstract

A rotatively oscillating separator comprising separating vessels each having cone-shaped separating plate disposed in the vessel, and drive means for rotatively oscillating said separating vessels , mixed rice consisting of unhulled rice and unpolished rice being fed onto the separating plates in the separating vessels at a given location to separate the unhulled rice and the unpolished rice from each other, the unpolished rice being discharged through raised peripheral portions of the vessels, and the unhulled rice being discharged through the central bottoms of the separating vessels. The drive means comprises a plurality of oscillatory drives provided at locations equi-angularly spaced around the separating vessels , said oscillatory drives each being upwardly inclined and operatively connected to the raised peripheral portion of the separating vessel to support it, said oscillatory drives being sequentially actuated at predetermined phases of delay to generate oscillatory motion to be imparted to the separating vessels, said each oscillatory drive including an oscillatory angle adjusting mechanism for retaining the oscillatory drive at the upward inclination and for varying an oscillatory angle in the rotative oscillation of the separating vessels.
