Design and Fabrication of Oil Extraction for Kachhi Ghani Waste Material

Abstract

The increasing demand for edible oils has led to the generation of large quantities of waste material from traditional oil extraction systems such as Kachhi Ghani. This waste still contains residual oil that can be recovered using appropriate extraction techniques. The present study focuses on the design and fabrication of a low-cost oil extraction machine to recover residual oil from Kachhi Ghani waste material. The system is designed to improve oil recovery efficiency, reduce waste, and enhance economic benefits for small-scale oil producers. The fabricated machine operates using a mechanical pressing mechanism powered by an electric actuator. Performance analysis shows improved oil yield and cost-effectiveness compared to traditional disposal methods. The developed system offers a sustainable solution for waste utilization in rural and small-scale industries.

Introduction

Kachhi Ghani is a traditional cold-press oil extraction method that preserves oil quality but leaves 8–12% of oil in the residual cake, causing economic loss and waste management challenges. Existing secondary extraction methods are often costly, complex, or environmentally unfriendly for small-scale rural producers.

This study develops an impact-type cylindrical oil extraction machine to recover residual oil efficiently while maintaining oil quality. The machine uses an actuator to compress and strike the oil cake in a chamber with a mesh, allowing oil to pass through for collection. It is fabricated from scrap materials, making it cost-effective, simple, and suitable for small-scale rural industries.

Results:

• Oil recovery increased by 6–10% compared to traditional methods.
• Produces high-quality oil free of solid contamination.
• De-oiled cake can be used as animal feed or organic fertilizer.
• Operates efficiently with minimal maintenance and moderate power input.
• Environmentally sustainable and promotes effective waste utilization.

Advantages: Simple design, low-cost, improved oil recovery, eco-friendly, continuous operation, and suitable for small-scale producers.

Limitations: Requires electricity, potential wear of impact components, careful alignment needed, limited to small-scale operations, and fabrication precision is essential.

Conclusion

1) Successfully designed and fabricated an impact-type oil extraction machine for recovering residual oil from Kachhi Ghani waste material. 2) Combines compression and mechanical impact to maximize oil recovery. 3) Maintains mechanical simplicity and affordability. 4) Testing confirmed improved extraction efficiency and reduced waste. 5) Demonstrated reliable and smooth operational performance. 6) Provides a sustainable and cost-effective solution for small-scale and rural oil production industries. 7) Enables better utilization of waste material and increases economic returns. 8) Shows that traditional oil extraction methods can be enhanced through simple mechanical innovation without compromising oil quality.
