| 概要 |
This study presents the development and evaluation of a village-type semi-automated coconut meat grater to improve efficiency, safety, and productivity in coconut processing. The machine addresses lim...itations of existing manual and electric graters by integrating an Arduino-based system with a servo motor for precise coconut positioning and a stepper motor-driven mechanical jack for controlled grating. Tests showed an average grating capacity of 4.60 kg/h, a grating efficiency of 69.21%, and a recovery rate of 65.72%. The prototype demonstrated a low specific energy consumption (0.00387 kWh/kg), underscoring its energy efficiency. This innovation enhances the competitiveness and sustainability of the coconut industry, particularly in countries like the Philippines, where coconut cultivation is economically significant.続きを見る
