Title:
RICE-PARTICLE-QUALITY DISCRIMINATING APPARATUS
Document Type and Number:
Japanese Patent JP3642106
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide the rice-particle-quality discriminating apparatus, wherein the constitution of an optical light-receiving means is simplified, the manufacturing cost becomes inexpensive and the fluctuation of the input voltage into an operating circuit is less.
SOLUTION: In a rice-particle-quality discriminating apparatus 1, the following parts are provided. A light source 7 projects light ray from the slant upper side to a sample grain particle moved from a sample picking hole 5. A dichroic mirror 8 classifies the amount of the vertical reflected light from the sample grain particle into the long-wavelength component and the short-wavelength component. Two photodetector 9 and 10 receive the amounts of lights having the respective classified wavelengths. A transmitted-light photodetector 11 receives the amount of the vertical transmitted light from the sample grain. The light ray is applied on one grain particle from the light source 7, from the slant upper side. A cracked-rice detecting photodetector 12, which receives the amount of the slant transmitted light from the sample grain particle, is provided.
