Development of a Cost-Effective Coconut Dehusking Machine

This study aimed to develop an affordable mechanized solution to address this challenge.A coconut dehusking machine prototype was designed, fabricated, and tested. It consists of a rigid steel frame, two counter- rotating cylindrical drums fitted with spikes, an electric motor, a V-belt drive system, and a control panel. Components were sized through structural and mechanical calculations. Fabrication utilized locally sourced materials within a 250,000 NGN budget.Testing showed the machine achieving 90% dehusking efficiency at 120 nuts/hour. Operational costs are minimized through a 1.5HP electric motor. Finite element analysis verified the structural integrity of machine components under operational…
