Development of Power Operated Coir Removal Machine

Abstract

In general, Coconuts are de-husked manually using either a machete or a spike. These methods require skilled labor and are tiring to use. Attempts made so far in the development of de-husking tools have been only partially successful and not effective in replacing manual methods. Considering the drawbacks of manual de-husking methods, and existing automated de-husker, power operated coconut de-husking machine was developed. This power operated coconut de-husking machine operates on 3-phase, 2 hp electric motor. It mainly consists of parts like frame, electric motor, speed reduction unit and de-husking unit. Single person is required for operating the de-husker. During the tests, average time required for de-husking a coconut was found to be 25 second, and the machine can dehusk 120-150 coconuts per hour. Therefore by using this machine time and labor cost is saved to great extent.
