The design and testing of a novel, laboratory tangential abrasive dehulling device (TADD) is described. The TADD can process eight 10-g samples at a time to provide a measure of grain hardness and an extraction rate based on flour color. When barley and grain sorghum were tested with the TADD, coefficients of variation ranged from 1.0 to 3.8 for the percent kernel removed at a given time. For 31 samples of sorghum, the abrasive hardness index ranged from 5.0 to 12.8 and extraction rates from 69 to 98%.
