In this communication, a new design of thin layer bed crop drying cum water heater has been
proposed and analysed for making the whole system operate throughout the year. Energy balance equations for each component of the system have been used to predict the analytical results. The system can be used to provide hot water in case the drying system is not in operation. The water heater below the air heater systems will act as a storage material for drying the crop during off sunshine hours.
