A comparison of labor-saving technologies for processing shea nut butter in Mali

Shea nut butter (karité) is a major cooking fat in semi-arid parts of West Africa. Its preparation by the traditional process involves long and arduous work by women. Several labor-saving technologies have been developed and applied in Mali. A manual press has been developed by KIT, with GTZ support. It is suitable for small groups of women where the ability to pay for equipment is limited or shea nut supplies are uncertain and other oilseeds are available. CEPAZE has developed two more mechanized alternatives with support from ATI and other donors. The first, a prototype of an animal-driven grinder/kneader, was not accepted in one village in Mali since the people were familiar with a motorized alternative. The animal-driven unit also requires further technical development. The second, a motorized grinder and centrifuge system, may be well suited for a larger, artisanal-scale commercial enterprise. By itself, the motorized CEPAZE grinder may be appropriate for service pressing of shea kernels as well as grain in larger villages.
