摘要：
In this work, a solar drying system of a cylindrical section which consists of a solar collector flat plate, drying chamber cylindrical section and a fan was built and designed for the purpose of drying 70 kg of bean crop. And there was an analysis of a thermal solar collector with flat plate absorption being obtained at the maximum temperature outlet of 71.4 degrees C at 11 am. At radiation intensity, 750 W/m(2) for air flow rate of 0.0401 kg/s was obtained at ambient temperature of 34 degrees C. The maximum average value of thermal efficiency of the solar air collector obtained from the calculation is 25.64% at air flow rate of 0.0675 kg/s, the maximum daily efficiency drying system was 18.41% at air flow rate of 0.0405 kg/s.
