Abstract
Some physical properties of the naked oat seeds were determined as a function of moisture content ranging from 9.56 to 18.07% (wet basis, w.b.). Seed length, width, thickness, and geometric mean diameter were increased from 7.89 to 8.81 mm, 2.32 to 3.09 mm, 1.85 to 2.77 mm, and 3.24 to 4.22 mm, respectively, with the increase of moisture content. The bulk and true densities of the seed samples were decreased from 682.1 to 533.1 kg/m3 and from 1,280.6 to 1,162.8 kg/m3, respectively. The average static friction coefficients of the seeds on the surfaces of plywood, stainless steel, and polypropylene knitted bags were increased from 0.403 to 0.674, from 0.371 to 0.496, and from 0.562 to 0.765, respectively, when the moisture content of these samples were increased from 9.56 to 18.07% (w.b.). The static angle of repose varied from 24.38° to 39.17° in the moisture content range.
