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.
