Apparatus for evaluating quality of raw coffee beans.

摘要

In an apparatus for evaluating raw coffee beans, a near-infrared light beam is applied to sample coffee powder (5), and a detector (26, 27, 28) receives light reflected from and/or transmitted through the sample coffee powder to generate a signal representative of luminous intensity of the received light. A memory device (122) has stored therein at least one of characteristic coefficients and appraisal coefficients for the sample coffee powder. A calculation device (123) calculates at least one of characteristic values and appraisal values of the raw coffee beans, based on the stored coefficients and the signal from the detector.
