The Malian Peanut/Groundnut Sheller is a simple machine, requiring less than $10US of materials. It is hand operated and is capable of shelling 50 kilograms of raw, sun-dried nuts per hour. It is made of concrete, poured into two simple fibreglass molds, some primitive metal parts, one wrench and any piece of rock or wood that might serve as a hammer. It accepts a wide range of nut sizes without adjustment. If necessary, adjustment is easily done in seconds. In Mali, it is estimated that one machine will serve the needs of a village of 2000 people. The life expectancy of the machine is around 25 years. Its design is public domain and we expect that local experience will improve the design as time goes by. We offer every possible technical assistance to non-profit groups planning to use this design in their programs. Commercial groups are welcome to use any information provided free of charge.
