Abstract


Some of the physical and mechanical properties of IARJAT2006019 Jatropha curcas L. fruits, seeds and kernels of Zaria origin were determined. The physical dimensions, which are the length, equatorial diameter (width) and breadth (thickness) of the fruits, seeds and kernels, were determined using a digital vernier caliper, reading 0.01 mm. The results of the physical dimensions were used to calculate the geometric mean diameter, arithmetic mean diameter, sphericity of the fruits, seeds and kernels. Other physical properties of jatropha curcas fruits, seeds and kernels determined were the surface area, volume, 1000 - unit mass, coefficient of static friction and angle of repose. Mechanical properties of the fruits, seeds and kernels determined were the rupture force and hardness. The mean length, equatorial diameter (width) and breadth (thickness) of the jatropha seeds was 16.92 mm, 10.38 mm and 7.54 mm. The mean rupture force of the jatropha seeds was 79.95 N at 7.0% db. The mean hardness obtained was 66.87 N. The results of some physical and mechanical properties obtained were used to design a modified jatropha oil mechanical extraction machine. The results obtained were within the range obtained by some known researchers.
