Integrated design, thermal testing and sustainability analysis of a motorized chicken roaster for low-carbon food processing

This study presents the design, fabrication, and evaluation of a motorized chicken roaster optimized for both domestic and commercial use. 3D modeling was conducted in AutoCAD and SolidWorks to optimize the geometry, ensure assembly accuracy, and identify potential interference among components. Key components in contact with heat (rotisserie trays, shafts, chamber) were fabricated from stainless steel UNS S30400 for its excellent corrosion resistance, while the structural frame and base used cast steel (mild steel) for strength and fabrication ease. Performance testing conducted at a heating temperature of 162.78 °C, over 90 minutes achieved a final meat moisture content of 59%, closely aligning with the target of 60%, and a maximum heat penetration depth of 47.05 mm into the chicken core. The design incorporates options for cleaner heat sources (CNG gas or electric heating) to reduce CO₂ emissions and uses long-life recyclable materials to enhance sustainability. The final prototype demonstrated uniform cooking performance and met food safety standards, making it suitable for deployment in both domestic kitchens and commercial food service environments.
