Calibration system in whiteness measuring device, artificial sample calibrator for the calibration system and method of manufacturing the same

摘要

The present invention is, brown rice equivalent of whiteness is a measure rice, the sensitivity adjustment in the vicinity of whiteness of milled rice equivalent to provide a calibration system in whiteness measuring device to realize the conduct instrumental error reduced using the artificial sample. A calibration system for a white measuring apparatus of the present invention is to place a sample of the measured rice housed in the measurement position of the body 2 whiteness measuring device 1, the measuring light in rice measured contained in the sample volume The irradiated, in the reflected light calibration in whiteness measuring device 1 for measuring a measurement rice whiteness and signal processing system, alteration to have brown rice, a whiteness such that measurement rice and whiteness and equal or approximate as rice The low inorganic material or an artificial sample calibration body 20 which contains the artificial sample 10 made of an organic material, is placed in the measurement position of the body 2, the sensitivity adjustment by whiteness measurement of artificial samples accommodated in the artificial sample calibration 20 It is intended to perform.
