ABSTRACT:
A color sorting apparatus has a chute from which grains come out in the form of a linear flux, a photoelectric detection device surrounding the flux and including light sources, light-receiving units each having a lens barrel having a filter unit and adapted to receive the light reflected by or transmitted through the flux of grains, and a jet nozzle which provides a jet of air in accordance with the signal from the light receiving units thereby to blow unwanted grains of different colors away from the flux, so that the desired grains and unwanted grains are separated from each other according to their colors. The filter unit consists of a plurality of filters carried by a plate member which is movably mounted on the lens barrel.
