Design and performance of a coconut dehusker machine

Md. Akhir Hamid, . and Mohd Taufik Ahmad, . and Ahmad Ngalim, . (2010) Design and performance of a coconut dehusker machine. [Proceedings Paper]

A mechanized coconut dehusker designed for industrial scale work load was fabricated and tested. The machine relies on a 5.5 Hp petrol engine to power a hydraulic pump that drives a set of double spike rollers. By rotating in different directions the rollers were able to grip the coconut exocarp and split the husks and nuts. The efficiency of the machine was tested for four local coconut varieties: Malayan tall respectively 92.5 and 85 for ripened and matured nut; Matag 85; Mawa 77; and Yellow dwaft 46. The machine is capable to dehusks 270-300 nuts/hr or 7-10 sec/nut. The estimated cost per machine is RM10 000.00.
