The current study aimed to use, besides solar, waste heat from exhaust gas of a diesel engine operated for milling grain, dry black nightshade seeds. Assessment thin layer models simulating drying kinetics seeds was performed in solar-exhaust greenhouse dryer on solar; gas; and modes. In solar mode, took 11 hours reach final moisture content 7.13% (db) an initial one 89.34% (db). mode were drie...

The purpose of this study was to determine the performance a hybrid dryer by combining utilization solar energy (solar dryer) and biomass power sources. Utilization thermal sources maximizing heat radiation which are absorbed directly into drying chamber in form transparent house with ventilation holes for fresh air enter moist exit. This process will produce hot circulation (convection) contin...
