摘要

This invention relates to an apparatus for evaluating the quality of rice grains. The apparatus comprises a near infrared spectrometer (3) having a bandpass filter (33) and detecting means (35a, 35b) for detecting the intensity of reflected light from the sample rice (55); control means (5) having a memory device (4b) for storing various values and a calculation device (4c) for pertorming various calculations; indicating device (6, 8) for displaying or printing the various calculated values: and a sample case (52) for being filled with the sample rice and being disposed at the measuring portion (37) within the near infrared spectrometer (3). The apparatus is capable of measuring the content percentages of pre-selected constituent or constituents, such as, of protein, either amylose or amylopectin and moisture of the rice grains, calculating a quality evaluation value of the sample rice based on the measured and calculated values and powers established for the pre-selected constituents, and displaying the calculated evaluation value of the sample rice.
