GRAIN QUALITY MEASUREMENT METHOD

摘要

PURPOSE:To evaluate the taste of unpolished rice even in the state of husks and at the same time estimate the internal quality evaluation value of a grain sample by automatically discriminating the type of the grain. CONSTITUTION:Near infrared rays are applied to a grain sample and the absorbance of the infrared rays for each wavelength is measured to obtain the spectrum of the grain sample. The spectrum of the grain sample is compared with a standard spectrum stored for each type of grain in advance to discriminate the type of the grain. Different calibration curves for each grain used according to the discrimination result are automatically selected and an internal quality evaluation value such as the chemical constituent value of the grain sample and/or viscosity is estimated by the calibration curves.
