This research paper focuses on the development of a mechanical system for extracting essential oil, considering its wide range of applications in medicine, perfumery, manufacturing, and pharmaceuticals. The study aims to address the need for efficient essential oil extraction, particularly from fruit wastes, by employing a direct steam distillation process using two prototype machines: a direct heat extractor and an electrically powered extractor. The research initially explored various design concepts, eventually narrowing down to the two most efficient options based on evaluations by technical experts. Comprehensive evaluations were conducted to finalize the specifications, materials, and manufacturing processes required for fabricating the essential oil extractors. The resulting prototypes underwent pre-testing to identify and rectify any minor issues prior to a thorough evaluation of their efficiency in extracting essential oil. Furthermore, the characteristics of the oil produced were also assessed. The results demonstrate that both prototype machines are capable of extracting essential oil; however, the direct heat extractor outperformed the electrically powered extractor in terms of several key factors. These factors include the percentage yield of essential oil, production cost, ease of oil extraction, durability, commercial viability, and aesthetics. Therefore, the machine utilizing direct heat is deemed superior overall. This research contributes to the field of essential oil extraction by providing a practical solution for effectively utilizing fruit wastes. The developed mechanical system offers a cost-effective and efficient approach to extracting essential oil, paving the way for potential advancements in the industry. The findings of this study can serve as a foundation for further research and development in the field of essential oil extraction machinery, benefiting various sectors such as medicine, perfumery, manufacturing, and pharmaceuticals.
