ABSTRACT
The inclined belt separator, or draper, separates seed by their relative ability to roll or slide, which is in turn determined by the seed’s shape and surface texture.
Uses
The seed mixture is fed onto an inclined draper belt which is moving toward the high end. The slope of the draper belt can be adjusted to more or less slope, to the slope that causes round seed to roll or slide downhill, while flat or rough seed can lie on the draper belt and be carried upward and fall off the high end of the draper belt (Figures 33.1, 33.2). While the draper is not in general use, it offers great flexibility in separating seed which differ in their relative ability to roll.
