Abstract

PURPOSE:To discriminate the drest grain, powdery grains and colored grains by irradiating two kinds of beams of different wavelengths to each grain of polished rice, and determining the transmittances thereof and finding the correlations between the two transmittances. CONSTITUTION:One grain 1 of polished rice is held in the opening 3 of a light shielding plate 2 and is moved in an arrow direction. It is irradiated with beams of wavelengths lambda2, lambda1 from light emitting elements 4, 6. The light part the grain 1 is photoelectrically converted with photodetectors 5, 7, and the signals are converted to digital quantities with A/D converters 10, 14 via amplifiers 8, 12 and effective signal discriminators 9, 13. The digital quantities are held in buffer registers 11, 15. A computer 16, inputted with the contents of the buffer registers 11, 15, discriminate the quality of the grain in accordance with the two transmittances and the difference between the transmittances as logical conditions, and outputs the drest grain, defective grains, the powdery grains in the defective grains and the rate of inclusion of colored grains in the prescribed amt. of the polished rice from an outputting device 17.
