Cereal grain color sorting apparatus |
摘要 |
In a color sorting apparatus comprising: a grain guide device); a grain feed device; optical detecting devices including illuminating devices for illuminating the grain, light-receiving sensors for receiving the intensity of light from the illuminated grain and backgrounds; and an ejector device for removing the grain, the illuminating devices comprise first light sources having a spectral energy distribution in a visible light region and second light sources having a spectral energy distribution in a near-infrared region, and the light-receiving sensors comprise a first light-receiving sensor portion having a high sensitivity to light in the visible light region and a second light-receiving sensor portion having a high sensitivity to light in the near-infrared region, so as to detect and remove foreign matter having a different color from the good grain in visible light region as well as to separate and remove other foreign matter having the same color as the good grain or being transparent in near-infrared region with one color sorting apparatus.
