<p>PURPOSE:To easily and accurately evaluate the quality of rice within a short time, by measuring the light absorbancy of sample rice using near infrared rays and operating the quality evaluation value of the rice on the basis of the measured value to display the same. CONSTITUTION:The sample rice charged in a supply hopper 10 is polished by a rice polishing apparatus 11 and ground by a sample grinder to be received in a sample container 13 and moved to the position directly under a near infrared analyzer 3. The light emitted from a light source 17 passes through a narrow-band pass filter 19 consisting of a plurality of filters 19a-19f having a wavelength region of 1,900-2,500nm to become near infrared monochromatic light having a specific wavelength to irradiate the sample rice in the analyzer 3. The diffused reflected light from the sample rice 24 is incident to detectors 21a, 21b to measure the intensity thereof. The measured values detected by the detectors 21a, 21b are sent to a control apparatus 4 to be stored in a memory apparatus 4b. The operation apparatus 4c of the apparatus 4 calculates the quality evaluation value of the rice on the basis of the measured values stored in the apparatus 4b and the calculation result is visually displayed or printed by a printer 8.</p> |
