  • Abstract:
  • in this paper, solar energy is the most promising of the renewable energy sources in view of its apparent limitless potential. Due to higher prices and shortages of fossil fuels and to reduce the fuel consumption used in the drying process, more importance is given to solar energy sources as it is freely available . For these purposes, an indirect type solar dryer was designed and developed to dry agricultural products. The efficiency of solar dryer is based on the absorber and it is made of different materials. In this project paraffin wax used to increase efficiency the indirect type solar dryer. The present study is aimed at investigating the feasibility of using a solar air heater with PCM to store the solar energy during the daytime, and to release it during the night. Advantages of the solar dryers used for agricultural product drying can be proved to be most useful device from energy conversation point of view that not only saves energy but also saves lot of time, occupying less area , improves product quality
