Grain cleaning technologies improve efficiency, accuracy

Today’s grain cleaning machines are complex pieces of equipment that use various methods to remove impurities that infiltrate grain during harvest, transportation and storage. The USDA has published several studies on the value of cleaning grain for corn, soybeans, wheat and barley. But those were released in the mid-2000s, and the technology behind grain cleaning has evolved in that time, becoming faster, more precise and economically feasible.
