Drying is an important post-harvest preservation technique of spices. As drying is an energy intensive process, accessibility to good drying methods is essential for the economical betterment of the farmers. Solar energy based drying techniques offer better return on investment to farmers. Developed hybrid solar drying system can be used for drying various agricultural products like spices, fruits and vegetables. The dryer has been coupled to an electric air heater having an auto controlling facility and blackened surface of absorber for improved drying efficiency.

The thermal performance of a single pass solar air heater with five fins attached was investigated experimentally. Longitudinal fins were used inferior the absorber plate to increase the heat exchange and render the flow fluid in the channel uniform. The effect of mass flow rate of air on the outlet temperature, the heat transfer in the thickness of the solar collector, and the thermal efficiency were studied. Experiments were performed for two air mass flow rates of 0.012 and 0.016 kg s1 . Moreover, the maximum efficiency values obtained for the 0.012 and 0.
