Purpose: This study aims to design, develop, and evaluate the performance of a compact dual-mode (hot and cold) oilseed extraction machine intended for household use. The specific objectives are: to design a dual-mode oilseed extraction unit that integrates both hot and cold pressing capabilities for domestic application; to fabricate a functional prototype using food-grade, durable, and cost-effective materials; and to evaluate the machine’s performance in terms of oil yield, extraction efficiency, and thermal regulation across different oilseeds.
Design/Methodology/Approach: The research adopted an applied engineering design methodology. It involved a comprehensive literature review, CAD-based conceptual modelling, prototype fabrication, and performance evaluation. Design criteria included energy efficiency, food-grade material selection, thermal regulation, and ergonomic suitability. Experimental trials were conducted on three oilseeds, groundnut, soybean, and sunflower, under varying thermal conditions to assess the machine’s yield and operational effectiveness.
Research Limitation: The machine was tested under controlled laboratory conditions with selected seed types. Broader trials across diverse home environments and a wider range of oilseeds would be required to generalise performance outcomes universally.
Findings: Results indicate that the developed machine effectively extracts oil yields of 250 ml (groundnut), 100 ml (soybean), and 220 ml (sunflower) per batch, affirming its viability for home-based oil production. The dual-mode functionality ensures nutrient retention in cold-pressed oils and improved yield under heated extraction, supporting both health and efficiency goals.
Practical Implication: The device empowers households to produce fresh, unrefined, and nutrient-rich oils, reducing reliance on commercially processed alternatives. Its user-friendly design and energy-conscious features make it suitable for widespread domestic applications.
Social Implication: By enabling small-scale oil processing, the technology contributes to local food sovereignty, lowers household expenses, and supports climate-conscious living. It has the potential to reduce socio-economic disparities related to access to healthy cooking oils.
Originality / Value: This study contributes novel insights into decentralised oilseed processing technologies. It bridges the gap between sustainable food practices and engineering innovation, offering a practical model for future research and development in green, home-based agro-processing systems.
