| dc.description.abstract | This study examines the Coconut Bristle Machine, designed to enhance productivity and efficiency in coconut processing. The machine includes outer structure, electric motor, drawer, holder, residue cover, and rotating shaft, and was tested according to Philippine Agricultural Engineering Standard (PAES) 251:2011. Tests were conducted using coconut husks of different maturities at three speeds: 500 rpm, 800 rpm and 900 rpm. Noise levels rose from 61.4-77.6 dB when idle to 74.5-84.9 dB during operation. Energy consumption was 0.234 kilowatt-hours, with power consumption at 811 watts voltage at 220 volts and current at 3.69 amps. Fiber extraction duration varied with drum speed and husk maturity, from 90.13 minutes (young husks at 900 rpm) to 18.723 minutes (mature husks at 900 rpm). The highest fiber weight was 2.867 kg at 500 rpm with young husks and the lowest was 1.817 kg at 900 rpm with mature husks. Moisture content ranged from 59.23% to 91.25%. Defibering capacity peaked at 185.22 g/min at 900 rpm with young husks, with the highest fiber recovery (77.49%) at 500 rpm with mature husks, and defibering efficiency at 75.01% at 500 rpm with mature husks. The economic analysis shows an initial investment of Php 26,310.00 and an annual income of Php 6,411.25 ensuring quick payback and high ROI. These findings emphasize the importance of optimizing both the cylinder speed and the maturity level of the coconut husk to maximize fiber yield and quality during the extraction process. The coconut Bristle Machine represents hope, progress and economic resilience for Aurora Province, promoting innovation and sustainability, potentially transforming the coconut industry into a model of economic prosperity and environmental responsibility. | |
