Abstract
A color sorting apparatus for beans includes a transferring device for transferring beans to be sorted to a detection position, an illuminating device for illuminating the bean at the detection position, a light receiving device for receiving a transmitted light transmitted through the bean and outputting a detection signal, a control device for operating the detection signal, comparing the detection signal operated with a predetermined threshold value to determine whether the bean is a good or defective one, and outputting an ejection signal when the bean is determined as a defective one, and a sorting device for removing the defective bean based on the ejection signal. The transferring device includes two endless belts defining therebetween a parallel gap on which the beans are held and a driving motor for driving the endless belts. The illuminating device is provided below the parallel gap defined by the two endless belts and the light receiving device is provided at a position opposite to the illuminating device with the bean being interposed therebetween. As the beans are stably transferred to the detection position, the detection signals based on the transmitted light from the beans are stably obtained without being influenced by the transferring device.
