Abstract Preview
Knowledge of grain physical properties is essential for designing processing equipment. This study characterized properties of five Nigerian grain varieties: maize (SAMMAZ-15), sorghum (SAMSORG-17), millet (SOSAT-C88), rice (FARO-44), and cowpea (IT97K-499-35). Properties measured included dimensions, sphericity, bulk density, angle of repose, coefficient of friction, and terminal velocity. Results showed significant variation among grains. Sphericity ranged from 0.65 (rice) to 0.92 (millet). Bulk density ranged from 520 kg/m3 (millet) to 780 kg/m3 (cowpea). Coefficient of friction varied with surface material, being highest on rubber and lowest on stainless steel. Terminal velocity ranged from 7.2 m/s (millet) to 12.8 m/s (cowpea). Data generated provides essential parameters for designing locally-appropriate processing equipment.
