Abstract: A power operated arecanut dehusker is designed, developed and its performance evaluated.
The major parts are the hopper, feeder, lead plate, cutting blade, shearing roller, friction plate and scraper. The feeder receives the graded fruit from the hopper and delivers it on the lead plate. The fruit is compressed between the rotating shearing roller and the lead plate. The teeth on the roller peel off the husk and the kernel is ejected out through the slot on the lead plate and the husk removed. A single phase 0.5 hp motor operates the machine.
From the studies, the optimum set - up of the machine for deriving maximum dehusking efficiency and Iower percentage of the number kernels damaged is at a speed of 35 rpm, blade angle of 600 and slot angle of 1400. At this set - up the machine gives an output of 9.0 kg dried fruit/h, with 84.5 per cent dehusking efficiency.
