Detail Design of a arechanut dehusking machine

areca nut peeling machine design

Areca nut has to be processed in dry condition by peeling the outer shell completely. Peeling of Areca nut is
very difficult by hand. However it is being done manually by using a sharp knife with a production rate of
3kg/hr. So it is essential to develop an agri-machine which will increase the production rate and safety to
labourers. Presently there are few machines available but these machines are not suitable for variety of sizes of
Areca nut which leads into the insufficient removal of outer shell of Areca nut. Therefore there is enough scope
to develop a agri-machine suitable for variety of sizes of Areca nut which will overcome these problems.
The present reserch work emphasizes on developing an Areca nut Dehusking agri-machine for three
different sizes of Areca nut. The concept is to shear-off the husk of the dry Areca nut by shearing force. The
features a Dehusking mechanism, and a power drive. The experiments were conducted by changing the blades,
and selecting the best method. The first experiment were conducted by mounting set of two cutters separated by
spacers for each size of Areca nut, then the set of two cutters were replaced by single cutters and the results of
both the experiments were compared and concluded that the single cutters were more efficient than the set of
two cutters in Dehusking the Areca nut
