Foniois a staple cropin western Africa. Because the fonio grains are so small, it is difficult to remove the brittle outer shell. "For hundreds of years, African women have carried out the painstaking task of preparing fonio by pounding and threshing a grain and sand mixture with a pestle and mortar.

Diakité's solution was a 50kg device that gently abrades the surface of the seed before passing through a rotating mechanism, which removes the husks.
This device is an example of
appropriate technology, because of its ability to solve a significant problem in developing countries and the ease with which it can be manufactured.
