About this book

This practical handbook describes the full process of oil production with a manual screw press, step by step, as well as detailing health and safety guidelines, equipment requirements, maintenance procedures, and approaches to sales and marketing. There are useful appendices which cover record keeping, financial considerations, and the use of a roller mill to speed up crushing, which is one of the essential preparatory stages for maximum oil production. Based on the authors' experience in Malawi, the book offers helpful advice to anyone starting up (or, indeed, already involved in) a small-scale project in oil processing.


Part 1: is there a local demand for oil and oilcake?; why manual processing?; why a screw press?; opportunities and risks; why start a small-scale oil processing enterprise?; what is needed to get going?; the decision. Part 2: Will the enterprise make a profit or loss?: how much finance is needed and when?; is it a good investment? what level of production has to be reached before the enterprise starts to make a profit?. Part 3: What is needed?. Part 4: How to do it, step-by-step.
