Barnyard millet (Echinochloa frumentacea L.), is presently dehulled manually. A 40–50 kg/h capacity dehuller driven by a 3.7 PS electric motor was designed, developed and optimized for process and machine parameters. The dehulling efficiency of 88.3±2.8% with 6.1±1.1% broken grain were obtained at optimized machine parameters (9 canvas strips over periphery of impeller and over hanging 3 mm width of canvas strip) and process parameters (8.6 m/s peripheral speed; 5 passes and 8.4% db moisture content).
