Designing and building a peanut-shelling machine to help people in third world countries such as Ghana/Haiti

摘要

A peanut shelling machine was designed and built to help improve the standard of living of people in third world countries such as Ghana and Haiti. Two prototypes were built to test the concept of using a wheel as a peanut sheller. Peanuts would go through a gap between a spinning wheel and a hard friction channel and come out on the other side fully shelled. The peanut sheller was powered using a crank. Second prototype was built after the concept of the spinning wheel worked after: testing the first prototype. Peanuts were shelled without breaking the kernels however a separator mechanism still needs to be built to separate the kernels from the shells.
