collector and drying chamber, velocity and moisture content of heated air, solar radiation and weight of product were measured. The maximum temperature inside chamber at the end of harvest season is about 60ºC, which was at least 20ºC above ambient temperature from 8 am to 4pm. Also a mathematical modeling which based on equations of heat and mass conservation was performed. Numerical results such as product temperature profile, remained moisture content of pistachio in different racks and drying rate due to time were plotted and compared withexperimental counterparts. It was found that proposed model have a sufficient accuracy with experimental results for forced convection dryers.
