The drying chamber is positioned at the outlet of solar collector. Drying chamber is made up of galvanized
iron metal sheet and has a rectangular cross section. The length, width, and height of the drying chamber were 0.5m,
0.4m, and 0.15m, respectively. The material to be dried is kept on perorated aluminium tray in a drying chamber, such
that air flows through the tray in cross flow manner. At a time one tray can be placed in the drying chamber with
material to be dried. Tray is placed at a distance of 0.25 m from the top of drying chamber.
In this dryer model energy from the sun is trapped between transparent cover and absorber plate, and heats the air by
the “Green House Effect” and thus, thermal energy of air (enthalpy) is used for drying of the target material.
