Measurement of Grain Dustiness.

Three grains---corn, sorghum, and wheat---were handled in the U.S. Grain Marketing Research Laboratory headhouse while dust and grain samples were collected. The amount of dust separated by the dust control system was considered a relative measure of the grain dustiness. A diverter-type grain sampler collected grain samples during each handling. Each grain sample was bagged separately and moved to the laboratory for individual analysis. Grain samples were washed in isopropyl alcohol to remove residual dust and sieved to remove broken kernels. The residual dust was separated from alcohol by filtering and weighed. Data show that the amount of broken kernels from a sample were not always related to dustiness, while seed residual dustiness was indicative of dust collected during handling.
