Design and Fabrication of Coconut Dehusking Machine

This paper presents the development of a coconut dehusking machine with an optimized design. The components of the machine include a metal frame, an electric motor, a pulley, rollers with sharp edges, a roller with flaps, a spur gear, a hopper, and a bearing. The metal frame provides support, and all components are mounted on it. Two rollers are mounted adjacent to each other on the metal frame using bearings, and the metal roller with a flap is connected to the motor used to maintain contact between the roller and the coconut. A reduction gearbox is used to reduce RPM and provides sufficient torque from the motor. A Hopper with a circular shape is used to drop the coconut into rollers for safety purposes. Rollers peel the husk with the help of rollers. The coconut exits the rollers without a manual operator, making the de-husking process safer, less labor intensive, and more effective.
