Abstract/Contents:"A frequently used machine in the seed industry is the indent cylinder that separates seeds according to length. In an attempt to make more precise separations than are possible with conventional machines, a special indent cylinder separator was developed using roundhole perforated metal. In this model, the entire cylinder was wrapped with sheet metal. Although the machine made effective separations involving small length differences, seeds tended to lodge in the squareshouldered indents. To eliminate this problem, a new cylinder with a self-cleaning feature has been designed, constructed, and tested. The separating area of the new cylinder is wrapped with a thin belt moving with the cylinder. The belt is held off the cylinder to provide space for a cleaning brush immediately above the cylinder. This brush, rotating with the cylinder, removes seeds lodged in the holes. Based on measured seed dimension, one cylinder was designed to remove pigweed from alfalfa, and another to remove Bermudagrass seed not in the hull (groats) from seed in the hull. Performance trials with both cylinders show that the cleaning brush removes essentially all lodged seeds without degrading the improved separating selectivity of square-shouldered indents. Separations are influenced by feed rates, cylinder speed and slope, and collecting tray heights. The required seed purity is achieved in a single pass for Bermudagrass. Multiple passes are necessary to achieve the required alfalfa seed purity."
