Long drying time and less control on dryingparameters in natural convection drying give way to forcedconvection indirect solar drying. In forced convection drying, anexternal blower supplies ambient air into the solar collector. Theincoming air gets heated inside the collector and this air thenflows into the drying chamber where the product to be dried iskept. The hot air absorbs the moisture from the raw crops andexits through the chimney. Along with the temperature andhumidity of incoming air, its distribution inside the dryingchamber is also important in the process of drying. The dryingrate and quality can be improved if these parameters are undercontrol in forced convection solar drying. In this paper, designand analysis of a novel drying chamber are presented to improvethe performance and energy efficiency of solar drying witheffective distribution of air inside the chamber. The variation ofvelocity with respect to different positions inside the dryingchamber is also studied numerically.
