Abstract


An existing jatropha oil extraction machine was modified. The main components of the modified machine are; The frame, hopper, feed rate controller, worm shaft, speed step down shaft, extraction  barrel, barrel clamp plates, choke, choke regulator wheel, choke lock knob, bed bearings, oil outlet, cake outlet, V- groove pulleys, V-belts, belt guard, belt guard cover, prime mover seating, and prime mover. The components of the modified machine were designed. The designs made include, the  determination of the following; power required to drive the machine, load that can be lifted by the screw, pressure to be developed by the screw thread, machine capacity, hopper capacity, belt selection, pulley selection, the frame and others. The determined design power of the machine was 2.64 kW. The load that can be lifted by the screw was 5.82 N. The pressure to be developed by the screw thread was 172.97 N/m2 and the machine capacity was 78.95 kg/hr. In the design of the components considerations were made to select materials for the fabrication of an effective, efficient and affordable machine which was constructed from materials readily available in the local market. The targeted users of the machine are Small and Medium Enterprises (SMEs) because they require minimum investment to set up. This could be a possible solution to the unemployment problem plaguing many Nigerians, by providing a source of self-employment with income.
