Abstract
A vital component in the design of threshers, dehuskers, shellers, and winnowers is the combination of geometrical, frictional, gravimetric, and aerodynamic characteristics. Consequently, to assess these qualities of barnyard millet grain, experiments were conducted. samples within a suitable moisture content range of 6.21 to 22.57% (db). were used in the experiments. Based on the moisture content appropriate for the majority of post-harvest operations, a range of 6 to 24% was selected. The geometrical mean diameter, equivalent mean diameter, arithmetic mean diameter, and square mean diameter increased from 2.05 to 2.24 mm, 2.63 to 2.87 mm, 2.18 to 2.38 mm, and 3.67 to 4.00 mm, respectively, with an increase in moisture content. Similarly, the coefficient of static friction with mild steel, GI sheets, plywood, and glass increased linearly from 0.369 to 0.533, 0.342 to 0.492, 0.288 to 0.301, and 0.314 to 0.363, respectively. Comparing the other three surfaces, it was found that mild steel had the highest coefficient of static friction while plywood had the lowest. Porosity, bulk density, and true density decreased from 0.572 to 0.429, 682.92 to 563.72 kg m-3, and 1318.95 to 1196.81 kg m-3 within the moisture content range, while angle of repose, aspect ratio, sphericity, surface area, volume, 1000 grain weight, coefficient of internal friction, and terminal velocity increased from 23.62° to 40.82°, 65.53 to 66.77, 0.6492 to 0.6569, 13.20 to 15.76 mm2, 4.35 to 6.22 mm3, 3.97 to 5.07 g, 0.556 to 0.863, and 4.42 to 5.23 ms-1.
