<p>PURPOSE:To measure and display the tenacity and hardness of the functional index mark and the moisture value and provide guidelines of the water adjustment and dipping time for rice boiling by measuring the functional index mark such as the tenacity and hardness of the boiled rice or the alpha level of rice starch and the moisture of the boiled rice. CONSTITUTION:A near infrared ray spectral analyzer 21 irradiates near infrared rays to boiled rice serving as a sample while the wavelength is continuously changed to detect the reflected light of the sample. A reflected light sensor 29 is connected to a controller 33 constituted of a spectrum data input section 30, a memory section 31 storing the calibration curves generated in advance for the constituent and quality of each sample and their coefficient values to calculate the constituent and quality evaluation value and a calculating device 32 calculating the constituent and quality evaluation value based on the calibration curves and coefficient values. The calibration curves are generated when the detected data of the reflected light and transmitted light quantity of the specific wavelength based on the known chemical constituents are analyzed. Chemical constituent values of unknown samples such as amylose and contained moisture are calculated based on these calibration curves.</p> |
