Abstract:

Mechanical extraction is commonly used to extract oils from vegetable seeds and a single screw extruder has been successfully reported to separate oil and cake from Jatropha curcas seeds. In this study, a single screw extruder was designed and analyzed using Finite Element Method (FEM) and Computational Fluid Dynamics (CFD). Three different geometrical dimensions of screw extruder were designed and analyzed using FEM and CFD with software ANSYS POLYFLOW to study simulation of the flow and the behavior of Jatropha dough through of a single screw extruder. In a preliminary study, this study focused to simulate the velocity profile and local shear rate indie section with a power law model. The result obtained revealed that three important are as in designing a single screw extruder were gap area (clearance) in the range of 0.5-1.0 mm, chamber area (normal pitch) in the range 17-22 mm and root area.
