Returning to the GATE system I blogged about previously (http://www.digivu.co.za/2008/05/solar-dryer-detailed-design-link/) this manual on edible oil extraction is outstanding.
The manual focusses on three case studies of the small scale expelling of sunflower, shea and palm oil, It also presents general in depth information on the world market, oil science, descriptions of all oilseed and plants, agronomy, expelling processes, expelling equipment and by-products and their use.

Overall the manual has a special focus on technical issues and development potential.
The three case studies:
- Shea Nut Processing in Mali
- Sunflower Seed Processing in Zambia
- Oil Palm Fruit Processing in Togo
cover the costing and finances of small scale processing in detail.
There is an enormous amount of detailed information presented that would definitely be of use to anyone considering setting up a business or a community project.
