Abstract:
Dehusking and shelling of are two crucial unit operations involved in post-harvest processing of maize. Physical characteristics of maize must be considered while designing the equipment to perform these operations. The given study was planned to investigate the physical properties such as principal dimensions, effective diameter, one thousand seed mass, sphericity, bulk and true densities, angle of repose and coefficient of static friction. The obtained mean value for maize grain for length, width, and thickness was 9.47±0.83 mm, 9.69±0.83 mm and 5.13±0.84 mm, respectively. The sphericity of the maize grain varied between, 0.737 to 0.998. The angle of repose of maize grain ranges between 27.1 and 32.1°. The mean value of the angle of friction was 29°, 27° and 25° for plywood, painted M.S. sheet and M. S. Sheet without paint, respectively.
