Abstract: In this work, the mechanical design calculations of the vegetable oil extraction plant presented in part I were show cased. Process description and flow sheet of the plant have been given in the design features in part I, and the mechanical design calculations are here based upon the figures obtained at various stages downstream in the process design. In fact, design stress due to load on hopper, agitated vessel, launder, sumps and down-comers, as well as extractor accessories of pipes, pumps, conveyor belts and screw, and miscella drainage, were also presented. Design was based on KPO as in Part I for the obvious reason that it is a simple oil which takes into consideration the properties of soyabean and palm oil, with an over design tolerance of plus/minus 10%. It was established from the mechanical design calculations that the volume of the extractor is 2.17m3 . Cost estimation of the designed extractor was carried out to also establish the cost of one unit to about three and a half million Naira (N3.5M), ($20,588.64). The design may be scaled up to any capacity for big industrial out-fit, and when fully developed and constructed, will serve the rural dwellers of the globe.
