Ejector for granular matter color sorter

PROBLEM TO BE SOLVED: To provide an ejector for a granular matter color sorter in which the burden of cleaning and maintenance, particularly for a nozzle part, is reduced.SOLUTION: An ejector 10 comprises a nozzle part, a solenoid valve part and a manifold part 14, and is characterized in that: the nozzle part includes a plurality of nozzle devices 16 each of which is independent of the others; the solenoid valve part includes a plurality of solenoid valve devices 19; the respective nozzle devices 16 correspond to the respective solenoid valve devices 19 by one to one, and air flow passages thereof are connected via an air flow passage 38 of a manifold 29; and the nozzle device 16 and the manifold 29 are detachably assembled and integrated, in a state of abutting a surface of the nozzle device 16 on which the air flow passage 38 opens, to a surface of the manifold 29 on which the air flow passage 38 opens.SELECTED DRAWING: Figure 6
