Description: The Philippines is the second-largest coconut producer in the world. More than half of the country?s annual coconut production is processed locally into copra. Traditionally, coconut dehusking is done at the farm level by means of simple tools. While it is accomplished with simple tools, dehusking relies mainly on human labor which can be quite tedious and hazardous. Hence, this study was conducted to develop a blade-type coconut dehusking machine for copra production The fabricated machine had a total dimension of 1370mm x 1275mm x 1665mm. It consisted of six major components, namely: feeding inlet and the dehusking unit, cleaning unit, husk and dehusked coconut discharge chutes, frame, power transmission system, and prime mover. The performance parameters of the machine such as dehusking capacity, dehusking efficiency, and percent coconut damaged as affected by the coconut sizes (Factor A: small, medium, large) and the operating speed of the dehusking roller (Factor B: 50 rpm, 75 rpm, 100 rpm) were analyzed using a factorial experiment in Completely Randomized Design. Comparison among means was done using Duncan?s Multiple Range Test at a 5% level of significance. The blade-type coconut dehusking machine was found suitable for farm-level dehusking operations during copra production. The machine can dehusk the desired number of coconut at reduced working time and labor requirements. Operating the machine at 75rpm resulted in a dehusking capacity and efficiency of 559 pcs/hr of 99.51% respectively, giving an increase of 311% in comparison to the manual coconut dehusking capacity of 180 pcs/hr.
