Kheer is a popular Indian dairy dessert prepared from concentrating milk with simultaneous cooking of rice grains. Conventional methods of preparing kheer have limited its mechanized production. Therefore, a conceptual design of continuous kheer-making machine has been prepared which among other components consists of a heating section for cooking kheer. The present study investigates the CFD analysis of fluid flow, heat transfer and fouling characteristics in the cooking section comprising of a helical coil heat exchanger heated with saturated steam on the outside. Development of such comprehensive models is appreciated to aid in efficient design of the continuous kheer making machine and to help overcome the adverse effects of milk fouling to obtain a product of desired quality.
