Solar energy represents non-polluting, inexhaustible renewable source of energy that can be utilized economically to supply man's needs for all the time. A Modified Solar cooker cum dryer was designed to facilitate solar drying and solar cooking in the same structure. Different components (Trays, Aluminium pipe, Blower, Fins, lens and Glass plate) of the solar dryer cum cooker were theoretically justified to find out the feasibility and advantage of the new dryer cum cooker. As with time the sun hour increase, so does the solar intensity increases. Fin type flat plate collector is provided for dissipation of heat to the drying chamber, which is just below the solar cooking chamber. Glass cover of solar collector normally should be at least 0.33 cm thick. Black body is provided for absorbing the radiation, which is coated to the cooking chamber. Lens is provided to reflect the heat to the drying and cooking chamber. Trays is provided for drying the food materials fruits and vegetable slices), which is attached to the aluminium pipe. Blower is equipment which increase the velocity of air, which is just below the fin type flat plate collector. The solar cooker was used as the solar collector for the solar dryer. The solar dryer was designed with 0.49m2 area. A solar cooker having size 900 mm x 750 mm x 300 mm the drying chamber for the dryer having size is 900 mm x 750 mm x 600mm. The plenum chamber of size 750 mm x 600 mm x 300mm has to be constructed. A tray having size 700 mm x 500mm is to be provided for supporting the material to be dried.

Keywords: solar dryer, solar cooker, thermal performance, solar energy.
