Quality measurement methods and quality measurement equipment of grain

摘要

PROBLEM TO BE SOLVED: To measure quality data with high accuracy though the moisture data related to the quantity of moisture contained in a sample is different, by selecting a measuring wavelength corresponding to moisture data from a plurality of measuring wavelengths, and receiving measuring light having the selected measuring wavelength to calculate quality data. ;SOLUTION: In a measuring means M, wavelengths are present corresponding to moisture data, and the measuring wavelength corresponding to the moisture data is selected from a plurality of the measuring wavelengths. For example, when the quality data of rice is measured, a quality planning apparatus irradiates a sample holding part holding a sample consisting of a plurality of uncleaned rices and the sample held to the sample holding part H with light, and receives measuring light having the measuring wavelength correlated with the quality data to be calculated from a material to calculate the quality data based on components contained in uncleaned rice on the basis of the received measuring light. The measuring means M includes a light source 1 emitting infrared rays, a spectral part 2 spectrally diffracting the transmitted light from the sample to obtain a spectrum and a processing part 3 calculating quality data on the basis of the spectrum.;COPYRIGHT: (C)1999,JPO
