om 8.0 to 2.0%. The sphericity and roundness values for selected grains are also in-cluded in Table 1. 2.3 Bulk

Density The bulk density of cereal grains is determined by measuring the weight of grain sample of known volume. The

grain sample is placed in container of regular shape, and theexcess on the top of the container is removed by

sliding string or stick along the topedge of the container. After the excess is removed completely the weight of the

grainsample is measured. The bulk density of the grain sample is obtained simply by dividingthe weight of the sample by the volume of the container. The bulk density gives good idea of the storage space required for known quantity of particular grain. Bulk density also inuences the effective conductivity and other transport properties. From the storagepoint of view, it is important to determine the effect of moisture content on the bulkdensity of grains because the bulk density of some grains increase with an increasingmoisture content, whereas it decreases for some other grains. The bulk densities of roughrice (Wratten et al., and short rice (Morita and Singh, were reported to in- crease linearly with an increasing moisture content between 1 and 1%, whereas the bulk densities of canola (Sokhansanj and Lang, , fababeans (Fraser et al., 1;Irvine et al., , axseed (Irvine et al., , gram (Dutta et al., 1a), lentils (Irvineet al., 1; Carman, , malt (Bala and Woods, , and soybean (Deshpande etal., decreased linearly with an increasing moisture content. Shephard and Bhardwaj(1a) reported that the bulk density of pigeon pea is higher than that of soybean andgrain sorghum but lower than that of fababean in the same moisture range. The bulk densities of rice bran (Jones et al., 1; Tao et al., , pigeon pea (Shepherd and Bhardwaj, 1b; rice (Jones et al., 1; Chandrasekhar and Chattopadhyay, , andwheat (Jones et al., have also been determined as function of moisture contentfor the different grains, wh
