Atiku et al. (2004) evaluated the performance of a bambara
groundnut sheller working on the principle of rollers
and pneumatically separating the shells from the seeds.
They got the maximum shelling and winnowing efficiencies
of 80 and 79.5%, respectively, at pod moisture content of5%
(w.b.) and feed rate of 93.6 kg h-1. The percentage of damaged
seed was about 20%, the percentage of partially shelled
(broken and unbroken seeds) and percentage of unshelled
pods were 10 and 7%, respectively, while the machine loss
accounted for 3%.
