Abstract
This study investigates the performance of a manually operated centrifugal honey extractor developed to enhance efficiency and usability for small-scale and sustainable beekeeping practices. The extractor incorporates a bevel gearbox mechanism that converts shaft rotation from a horizontal to a vertical axis, enabling ergonomic and energy-efficient operation. The primary aim was to design a cost-effective solution that supports low-resource beekeepers while maintaining high honey extraction performance. To evaluate its effectiveness, performance tests were carried out under varying honey loads. Key performance metrics included extraction efficiency, rotational speed, user-applied force, and extraction time. The results revealed an extraction efficiency ranging from 92.5% to 96.8%, demonstrating the device’s capability to extract honey effectively with minimal wastage. User effort increased with rotational speed, peaking at 16 N at 140 rpm—an effort level deemed acceptable within ergonomic standards. The extraction time varied from 60 to 110 seconds depending on the honey load, highlighting the machine’s adaptability to different operational conditions. The inclusion of the bevel gearbox significantly reduced the manual effort required, contributing to smoother and more stable operation, even during prolonged use. Overall, the extractor proved to be a reliable and user-friendly tool suitable for decentralized honey production. Its simple construction and mechanical efficiency make it ideal for rural or remote areas where electricity access is limited. The study concludes that the manually operated centrifugal honey extractor is a practical and sustainable alternative for small-scale beekeepers. Future design improvements could include an integrated braking system and ergonomic modifications to further enhance usability and reduce operator fatigue.
