Effect of Moisture Content and Variety on the Some Physical and Aerodynamic Properties of Sesame Seeds Relevant to Its Processing.

The physical and aerodynamic properties of black white sesame were determined at Moisture Content(MC%) range 8.5 – 30.6%(d.b).The major, minor, intermediate, arithmetic mean, geometric mean diameters sphericity, projected area the two varieties 2.96 3.94mm, 1.47 -2.40mm,0.54 -1.26mm,1.66 2.50mm, 0.78 - 3.66mm 26.53 93.45, 1.91 42.08mm2 respectively.The increase in MC resulted decrease true density from 1038.61 994.93 kg/mm2 1039.61 998.47 for seed terminal velocity ranged 3.12 7.82m/s while 3.16 7.94m/s 306% (d.b).The drag coefficient 3.750.31 2.26 0.23 respectively as 30.6% (d.b) Reynold number varied 2363.9 23067.3 3401.5 15121.6 significantly with variety MC.This findings are prerequisite design selection separating machine. A pneumatic separator can be designed provision effective separation undesired light material average below 5.17m/s 5.67m/s seeds respectively.
