A rotationally oscillating separator for separating mixed rice into unhulled rice and unpolished rice after the rice have passed through a rice huller to remove the hulls from rice. The separator comprises a vertical rotating shaft supported for rotation and having an axis, means for rotatively driving the rotating shaft, said rotating shaft including eccentric sections offset from the axis of the rotating shaft, separating vessels rotatably mounted on the eccentric sections and having a plurality of segmental separating plates disposed in a cone-shaped configuration within the separating vessels, retaining means on the separating vessels for preventing them from freely rotating, each of the eccentric sections having its axis, an upward extension of which is at a slight angle to the axis of the rotating shaft such that it intersects an extension of the axis of the rotating shaft at a point above its eccentric section, whereby the separating vessels are inclined relative to a horizon so that they are rotationally oscillated around the points of intersection between the extensions of the axes of the eccentric sections and the axis of the rotating shaft as phantom fulcrums, as the rotating shaft is rotated.
