APPARATUS FOR DETERMINING STATE OF GRANULAR SPECIMEN

PROBLEM TO BE SOLVED: To automatically calculate the existence of immersed break grains and a ratio of them to the sampling number, and rapidly and accurately determine the quality based on photometry data of a granular specimen containing moisture. …SOLUTION: A tray 72 stores water 58. Polished rice 56 is immersed into the water. After the polished rice is left for a predetermined time (approximately 20 minutes), a scanner 34 picks up an image of the polished rice 56 (measures a light from the polished rice 56). An actual image data and a pseudo image data are acquired based on the measured data. The pseudo image data is acquired by enlarging/reducing the actual image data. Since the existence of the immersed break grains is determined from a difference between the numbers of pixels in both images, the degree of interfusion of the immersed break grains can be rapidly and accurately determined in comparison with a visual determination by a worker. …COPYRIGHT: (C)2005,JPO&NCIPI
