Abstract
A color sorting machine sorts particles of different colors from raw material such as cereal grains or the like. The machine has a down chute descending towards a front side of the machine for letting raw material particles flow down linearly, a photoelectric detection device which subjects the raw material particles jumped out of the down chute to light and discriminates different-color particles in accordance with difference in reflected light, and a nozzle device which injects air to and blows off the different-color particles. The injection nozzle device is situated on the rear side of the machine with respect to a coming-down locus of raw material particles from the down chute and close to the coming-down locus. The sorting machine further comprises a dust collecting device which is situated on the front side of the machine with respect to the coming-down locus of the raw material. The dust collecting device has a dust collection opening which is substantially opposite to the injection nozzle device with the coming-down locus interposed therebetween, sucks in and discharges dust scattered from the raw material. The color sorting machine is highly precise in sorting different-color particles and facilitates cleaning of the dust collecting device.
