Abstract

Abstract: The solar drying system utilizes solar energy to heat up air and to dry food materials which in turn helps in preserving agricultural product for long duration in ambient condition. In light of the impediments of the normal sun drying for example openness to coordinate daylight, obligation to pests and rodents, absence of proper monitoring and the raised expense of the mechanical dryer. A minimal expense sunlight based dryer is subsequently evolved to cater for this limitation. this project presents the plan and development of a domestic passive solar powered dryer. The dryer is composed of solar collector (air heater) , a solar drying chamber with three cloth (net) tray ,inlet for air at the bottom and an outlet with exhaust fan operated by solar panel fitted of the top of the chamber. The air permitted in through air inlet is warmed up in the solar collector and diverted through the drying chamber where it is used for drying
