N2  - A solar dryer with a solar air heater, rock bed heat storage  was designed, fabricated and tested without load. The absorber plate of the solar air heater was corrugated iron sheet having absorber area of 9 m2 and 0.7315 m3 of ordinary rough gravel was used as heat storage medium.  The performance of the solar dryer for the selected clear,  clouded , rainy and the day after rainy days, has been presented.  The system was found capable to smoothen the temperature in the  chamber during day time and maintain the temperature 4-8°c  above the ambient during most of bright as well as dull days.  The solar dryer was also tested with a cowl to observe the  possible use of wind energy to force air through the system.  A simple mathematical model is developed to predict the  temperature profi1e through the system, working by natura1  convection. The mode l was found capable of predicting closely the temperatures through the system and the average chamber  temperature
