Development of a Manually Operated Multi-purpose Roasting Machine

Aim: The aim of this research is to design and fabricate multi-purpose roasting machine.

Study Design: Development of a manually operated multi-purpose roasting machine was achieved with the aid of conceptual sketch, design analysis and creo parametric software.

Place and Duration of Study: Department of Mechanical Engineering, Federal University of Technology, Akure, Ondo State, Nigeria, between July 2014 and October 2016.

Methodology: Design of the developed multi-purpose roasting machine was done using creo parametric software. Some factors were considered before fabrication of the developed machine such as selection of materials, operating parameters, manufacturing processes and functional requirements.

Results: The multi-purpose roasting machine was developed and tested on food items (maize and plantain).

Conclusion: The multi-purpose roasting machine was developed based on the design. The machine developed is a simple technology which can be easily operated by a single person of an average height of 1.4 m. The developed machine is a capable of roasting food items (maize, yams and plantain) depending on the choice of the operator and season of harvest. The bill of engineering measurements and evaluation (BEME) of the developed machine is 231.26 dollars.
