| Abstract | ||
| Physical properties such as principal dimensions, surface area, projected area, volume, mass of 1000 seeds, true and bulk densities and porosity for faba bean and lentil seeds were measured and calculated at different levels of seed moisture contents. The obtained results showed that, the principal dimensions, geometric and arithmetic diameter, surface area, actual and calculated volume, sphericity, mass of 1000 seed and porosity of faba bean (pods and seeds) and lentil seeds generally increased linearly with the increasing of moisture content. For faba bean pods and seeds, shape parameters (flakiness ratio Fr and elongation ratio Er) increased with the increase of moisture content but aspect ratios R1 (W/L), R2 (L/Th) and R3 (W/Th) of faba bean pods and seeds decreased with the increasing of moisture content. The values of projected area for faba bean and lentil seeds were also increased with the increase of moisture content. On the other hand, the results also showed that, both of bulk and true densities decreased by increasing the moisture content. Mathematical relationships were also developed relating the obtained values of all physical properties with the change in seed moisture contents. | ||
