Individual modes of heat transfer were estimated for the baking of roti, art Indian traditional product, in a tandoor oven. Mathematical expressions were proposed for the heat adsorbed by and transferred to roti during baking. Heat transfer parameters such as thermal conductivity and emissivity for roties were determined. Conduction and radiation from refractory surfaces were more prominent (51.4 and 44.0%, respectively) than other modes of heat transfer and conduction contributed more to the product quality aspects when compared to other modes of heat transfer.
