Computer-Aided Engineering Process for the Development of a Bread Baking Biomass Oven.

Area of Science:

• Engineering
• Sustainable Energy
• Rural Technology

Background:

• Conventional ovens are often inaccessible or expensive in rural areas.
• Limited energy access hinders efficient bread baking in rural communities.

Purpose of the Study:

• To design and assemble an efficient biomass oven for bread baking tailored to rural contexts.
• To optimize heat distribution and combustion for improved baking performance.

Main Methods:

• Utilized computer-aided design (CAD), manufacturing (CAM), computational fluid dynamics (CFD), and finite element analysis (FEA).
• Optimized combustion and cooking chambers for efficient heat transfer.
• Conducted performance tests measuring temperature distribution and combustion efficiency.

Main Results:

• The assembled oven achieved suitable baking temperatures (below 473.15 K) with good heat retention and uniform distribution.
• Demonstrated near-zero oxygen concentration at the chimney exit, indicating complete combustion.
• Outperformed traditional ovens in temperature control and combustion efficiency.

Conclusions:

• The developed biomass oven is an efficient and viable technology for rural bread baking.
• The design addresses the specific needs of rural communities by providing a cost-effective and accessible baking solution.
• This innovation promotes sustainable energy use in underserved areas.
