Groundnut shelling is a fundamental process in post-harvest management. Manual shelling is inefficient and laborious with low throughput. Motorised shellers experience less than 100% shelling efficiency and varying levels of kernel damage, hence, the need for optimization. Research work involving many factors require large numbers of experimental runs, resulting in high costs and are time consuming. Taguchi design of experiments enables to arrive at best parameter combination for optimal conditions with least number of analytical investigations. In this work, Taguchi method with S/N and ANOVA techniques were applied to optimize groundnut sheller performance involving the influence of six machine and groundnut factors on three output parameters. Best output results were obtained as follows: Throughput per unit power consumption of 921.03 (kg/h)/kWh at 12.2 m/s shelling speed, rubber paddle shelling blades, CG 7 variety, 6% mc, 1200 kg/h feed rate and 10 mm concave clearance. Shelling efficiency of 99.08% at 12.2 m/s shelling speed, rolling steel pipe shelling blades, Valencia red variety, 6% mc, 2000 kg/h feed rate and 10 mm concave clearance. Kernel mechanical damage of 1.25% at 7.4 m/s shelling speed, fixed rubber pipe shelling blades, Valencia red variety, 12% mc, 800 kg/h feed rate and 15 mm concave clearance.
