MORINGA SEED DEHULLING MACHINE: A NEW CONCEPTUAL DESIGN

This work aimed at designing and fabricating a Moringa seed dehulling machine using another design concept. The dehulling mechanisms includes a dehulling shaft that accommodates the dehulling drum of diameter 100mm and thickness 2.5mm and spikes 40mm long. The dehulling machine for Moringa seed processing is powered by an electric motor, pulleys, belts, shafts and bearings. The chaffs leave the machine through a slot created in the dehulling chamber while the seed fall through a screen under the action of gravity to a tray placed under the dehulling chamber. The overall efficiency of this machine on dry basis was 65.9 % and on wet basis was 52.5 %
