Development and performance evaluation of an improved electric baking oven for baked products

An improved electric baking oven was designed and fabricated using locally available materials for baking cakes and biscuits. Provisions of necessary adjustments were employed for ensuring uniform distribution of heat in all trays of the baking chamber. Its baking characteristics in terms of baking time, specific volume, and product quality in terms of sensory attributes were evaluated. The oven was found to be quite satisfactory in functioning for baking cakes and biscuits. Total time was only 15-28 min for baking the cake samples in the oven. On the other hand, comparatively, a bit longer time 18-35 min required for baking the biscuit samples. Baking cost was lesser in baking small-sized cakes and biscuits than those of large sized. The quality of baked products was better in terms of taste, color, flavor, texture, and appearance than ordinary market products. Loaf volume of each cake (with 4 × 5 × 8 cm³) was 100%, which gave specific volume of 652.8 cm³/kg. Similarly, the specific volume of biscuits was 810 cm³/kg. The electric baking oven is quite efficient in baking quality cakes and biscuits uniformly, which can be provided to rural small entrepreneurs for commercial manufacturing of biscuits and cakes.
