African locust bean (ALB) seeds are processing into afitin through a succession of operations, of which dehulling of pre-cooked seeds. Dehulling is laborious for processors. To remove this constraint, a motorized dehuller has been developed. This study aims to evaluate the effects of the setting gap between the fixed and mobile grids of dehuller on these performances. Boiled ALB seed were subjected to mechanical dehulling with inter grid gap varying from 2 to 25 mm. The obtained results showed that, when the gap varies from 2 to 25 mm, the dehulling rate decreases from 100 to 0%, the breaking rate from 50.83% to 0%. The machine performs well when ALB seed cooked during 4 h and grids’ gaps in the range of 5 to 15 mm. The values of these cited parameters that give the best performance are obtained when gap’s adjustment is fixed at 9 mm.
