The box is lled with grain, then the front panel is quickly removed. This allows the grain to ow to its natural slope. This slope is taken asa measure of the angle of repose. The emptying angle of repose has been measured forfababeans (Fraser et al., 1, Irvine et al., , gram (Dutta et al., 1a), oilbean seed(Oje and Ugbor, , and axseed and lentils (Irvine et al., . Oje and Ugbor (found that the emptying angle of response of oilbean seed was considerably higher than for soybean, corn, and wheat. This was probably because the smooth surface of oilbean seed which makes it easy for the seeds to slide on each other. Dutta et al. (1a) showedthat the emptying angle of repose increased with an increase in moisture content of gramwhich could be characterized by second-order equation (Table . 2.8 Bulk Volume Shrinkage Data are required on bulk volume shrinkage of grain for the mathematical solution of drying processes (moisture desorption). The bulk volume shrinkage is determined by plac- ing grain sample in cylindrical container, exposing it to an air stream, and recording continuous changes in mass
