Abstract

The method for presenting grain for NIR spectography examination includes causing the grain to move downward across a sloping presentation surface; associating the optics of an NIR spectography apparatus with the presentation surface to permit light from the optics to be projected into the curtain of grain at a substantial right angle with respect to the direction of flow of the curtain of grain over the presentation surface. An apparatus for presenting grain for NIR spectography examination includes the structure for practicing the aforementioned method.
