FBP LC Sheller

Background

The Full belly Project is an organization which creates low cost, simple technological solutions to be implemented in developing countries. One of these solutions, the Universal Nut Sheller, minimizes the work load of women in Western Africa by allowing nuts to be shelled through this device rather than by hand.

Abstract

To improve the Universal nut sheller, the LC Sheller design lowered the cost and weight of existing design using locally available and light weight materials.

Construction instructions

Equal mix (by volume) of cement, sand, clay and sawdust. Use fine grained clay, obtained by running dry, crushed clay through a sieve or screen. Also use fine sawdust, as opposed to wood shavings. Mix material dry, then slowly add water while mixing until desired consistency is obtained. This should be enough water for all materials (especially cement) to be wet, but is not too hard to mix. A slightly less-than cottage cheese wetness is acceptable. Follow Full Belly instructions as normal. Instructions http://www.fullbellyproject.org/Documents/UNS.pdf

Next steps

While improvements were made to the UNS, additional materials testing could result in a mixture that more thoroughly meets the Fully Belly Project's criteria. The final mixture decided upon is a base to move from.
