Again, the modification on the twin-blade tool with manual feeding of coconut was taken as a part of the project
at KCAET, Tavanur, India [3]. It was mainly intended for small-scale application. The machine comprised of a cam and
a follower which was connected to a hinged movable-blade for separating the movable blade from the stationary blade
and then re-setting the former on the latter quickly. The cam and follower mechanism was intended to allow dwelling of
the two blades in the juxtaposed position for 2800
and separation of the blades for the remaining 800
, and then quickly resetting
the movable blade to the juxtaposed position. The cam is designed in such a way that the closing time of blade is
2 seconds, so that we can utilize that time for impaling the coconut into the juxtaposed blades and the opening time of
blade was one second. The machine required 12-20 seconds for husking a nut depending on the skill of the operator. The
major problem related to this machine was that it was bulky and costly not that much convenient for small-scale
applications and in case of large scale, it would be time consuming and required skill.
