Statement

In places like Haiti and certain West African countries, peanuts are a significant crop. Most peanut farmers shell their peanuts by hand, an inefficient and labor-intensive process. Our goal is to build a low-cost, easy to manufacture peanut sheller targeted at individuals and small cooperatives that will increase the productivity of the peanut farmers. Further, this peanut sheller should be manufacturable with materials that are readily available in the target communities. Our target throughput is approximately 50 kg (110 lbs) per hour.

Customer Needs

Must remove the shell with minimal damage to the peanuts.
Electrical outlets are not available as a power source.
A large quantity of peanuts must be quickly shelled.
Low cost.
Easy to manufacture.
