Abstract: An ejector system for a color sorter, eliminates particulate matter by air by detection of the particulate matter falling from an end of a transfer device at a predetermined position, and has a nozzle part in which a plurality of air flow paths that communicate with a plurality of nozzle holes are formed. A manifold part is provided with a plurality of electromagnetic valves that communicate with an air space communicating with a compressed air source and in which a plurality of air flow paths for supplying compressed air to the corresponding air flow paths in the nozzle part by the operation of the respective electromagnetic valves are formed. The nozzle part and the manifold part are separably integrated while open surfaces of the air flow paths in the nozzle part and open surfaces of the air flow paths in the manifold part are brought into contact with each other.

Abstract: A rotatively oscillating separator comprising separating vessels 4 each having cone-shaped separating plate 5 disposed in the vessel, and drive means 6 for rotatively oscillating said separating vessels 4, 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.

Abstract: A rotary shaking separator for separating unhulled rice and unpolished rice from each other includes at least one separating vessel and a plurality of drives located at even intervals on the peripheral edge of the separating vessel, the plurality of drives being actuated to bring the whole of the separating vessel into a rotationally shaking motion.

Abstract: An object of the present invention is to provide a rotary shaking separator, which can maintain a constant separating accuracy without any failure in separation which might possibly occur in the same separating vessel, and which is not required to have a rotary shaft inserted though a central portion of the separating vessel.
