Abstract
Groundnut shelling is done by either by hand shelling
or by hand or pedal or power operated decorticators. Hand or
pedal operated decorticators have low capacity (below 80 kg/h)
and have no facility to separate kernels and husk. Whereas power
operated decorticators have these facilities but they are costlier.
The Pedal Operated Rotary type Groundnut Decorticator-cum
Cleaner was, therefore, developed to bridge these two extremeties.
The machine consists of mainshaft which is driven by
chain and sprocket through pedaling which rotates the rotary unit in decorticating cylinder where decortication takes place. A blower
driven by pulleys blows husk and separates kernels.
Tests indicated that weight of machine was 85.5 kg. Its
average decorticating capacity was 120.72 kg pods/h, average
output capacity was 54.32 kg kernels/h, average decorticating
efficiency was 84.69 %, average cleaning efficiency was 87.76 %,
breakage was 5.76 % and its cost of operation was found to be Rs.
23.28 /100 kg kernels.
Machine showed satisfactory results and it was
suitable for small and medium farmers.
