Universal nut sheller

The universal nut sheller (UNS; formerly called the Malian peanut sheller) is a hand-operated machine capable of shelling raw peanuts.

It is made of concrete poured into two fibreglass molds, metal parts, one wrench, and any piece of rock or wood that can serve as a hammer. It accepts a wide range of nut sizes without adjustment. Operators can make necessary adjustments. The life expectancy of the machine is around 25 years.

The Full Belly Project is working to establish businesses that manufacture and distribute appropriate technologies such as the Universal Nut Sheller.
