Design Analysis of a Palm Fruit Digester

Abstract

This study focused on the design analysis of a palm fruit digester to enhance efficiency and sustainability in palm oil production. Key objectives included determining the maximum bending and torsional moments, assessing belt tension, calculating power requirements for the driven pulley, and estimating fabrication costs. The analysis revealed that the Power required for the driven pulley, operating at a reduced speed of 659 rpm with a motor power of 0.75 kW, is 1.59 kW, underscoring the need for adequately specified motors. Belt tension calculations, with tensions of 5.084 N and 2.4 N for the driver and driven pulleys, respectively, confirmed sufficient power transmission. Additionally, the bending and torsional moments were determined to be 4280 Nmm, validating the shaft design's structural integrity and capability to withstand operational forces. These results affirm the digester's reliability and efficiency. The digester was designed using SolidWorks and fabricated with locally sourced materials, promoting sustainability and accessibility for small-scale producers. Its innovative design enhances palm oil extraction while serving as a model for future advancements in processing technology. Recommendations include scaling up industrial production, conducting further research on adaptability for other crops, and collaborating with stakeholders to support adoption. Dissemination of the Design to small-scale processors and continuous performance monitoring are also advised to maximize impact. This project represents a significant step in sustainable palm oil production, with the potential for industry-wide transformation and economic growth.
