Abstract:
Maize or corn (Zea mays L.) is an important cereal crop of the world. The average value of maize grain dimension was determined in this study at various moisture content. The average length (8.192), width (6.20) and thickness (4.30) of the soaked maize were linearly increased according to moisture content. Arithmetic mean diameter (6.21), Geometric mean diameter (6.00), Squire mean diameter (10.42), Equivalent diameter (7.55), Degree of sphericity (0.75), Aspect ratio (0.76), shape factor (6.43) and angle of repose of soaked maize were increased with an increase in moisture content. The bulk density, true density, and porosity of the maize grain were found to decrease with increasing moisture content. The bulk density of maize grain decreased linearly from 806.4 to 768.3 kg/mm³. The true density of maize grain decreased linearly from 1109.4 to 1065.8 kg/mm³ for maize, respectively. The porosity was calculated as a function of the bulk density and the true density of the grain. It was found to decrease linearly from 32.3 to 27.8 for maize grain. The angle of repose of maize is different at different moisture content. The moisture content of maize was 8, 10, 12, 14, and 16 and the angle of repose was found at this moisture content was 19.98, 21.12, 23.20, 24.96, and 27.98 respectively.
