The Technological Developments in Power Operated Coconut (Cocos nucifera L.) Dehusking and Deshelling Machines: A Review

The aim of this paper is to present recent developments related to power operated coconut dehusking and deshelling machines. Coconut is a fruit of great value as every part of the fruit is commercially viable. To utilize coconut fruit and its parts, it is necessary to remove the coconut husk and to break the coconut shell. Coconut husking and shell breaking are traditionally labour-intensive operations. Both the mentioned operations are tedious, require skills and prone to harm the worker. There are many attempts to reduce the human drudgery involved in coconut processing operations by making machines which can dehusk and deshell the coconuts. The paper simply explains working mechanisms, features and capacity of recently developed machineries in the field of coconut dehusking and deshelling. The different types of working mechanisms used for coconut dehusking and deshelling can be overviewed from this review, which can be helpful for further developments in this field.
