Drying is a very sophisticated process which consumes a large amount of energy. Solar energy can be used as an alternative or supplementary energy source to fossil fuels. Solar dryers are common ways for saving fossil fuel consumption during agricultural products drying. In this study, the performance of an active solar dryer equipped with an energy recovery system was investigated at three levels of drying air temperature. The results showed that the energy recovery system was able to increase inlet air temperature by 16.8, 18.5 and 18.9 ° C at drying temperatures of 55, 65 and 75 oC, respectively. Meanwhile 47.8, 42.9 and 40.9 percents of the dryer exhaust air energy were recovered respectively at these conditions which subsequently led to a reduction of 30.7, 19.2 and 14.7 percents in electrical heater energy consumption.
