Design & Fabrication of Semi-Automatic Coconut Dehusking, Water and Shell Separation Machine

Abstract

World’s third largest coconut producing country is India. All part of coconut is useful. Coconut husk is used
in coir industry, water as nutritious liquid, shell as a fuel and copra as a food. The scope of this project is to design and
fabrication of semi-automatic machine used to separate husk, water and shell from the coconut. The dehusking of
coconut is the most time-consuming operation since it is hand operated using a machete so injuries sustained by
dehuskers to their hands and other parts of body. it is dangerous and may causes back pain to dehuskers. The first
process of the machine is to remove husk from coconut with the help of rollers having pointed spikes on its periphery.
After that the second process is to make a hole in shell to remove water from it then last the process is shell removing
process with the use of cutter. By utilizing above technique, coconut can be dehusked, deshelled and water extracted from
it. Moreover, the system will be cost effective.
