Prior to this, Baboo (1981) developed a device for dehusking dry areca nut fruit. The device comprised a scissor mechanism, a frame, a platform and a pedal operated lever mechanism. The device, which was operated by two workers, could produce 13.4 kg of areca nut per hour. Earlier still, Wang (1963) proposed a mathematical model for the design of a frictional roller poha-berry husking machine. The model not only indicated that both friction and normal forces caused the husking of the berry but also provided an estimate of roller size.
