Abstract:
A rotatively oscillating separator comprising at least one separating vessel having a raised peripheral portion and a cone-shaped separating plate disposed in the vessel, and drive means for rotatively oscillating said separating vessel, mixed rice consisting of unhulled rice and unpolished rice being fed onto the separating plate in the separating vessel at a given location to separate the unhulled rice and the unpolished rice from each other, the unpolished rice being discharged through a portion of the raised peripheral portion, and the unhulled rice being discharged through a central bottom of the separating vessel, characterized in that said drive means comprises a plurality of oscillatory drives provided at locations equi-angularly spaced around the separating vessel, said oscillatory drives each being upwardly inclined and operatively connected to the raised peripheral portion of the separating vessel to support the separating vessel, said oscillatory drives being sequentially actuated at predetermined phases of delay to generate oscillatory motion to be imparted to the separating vessel, 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 vessel.
