Design and Development of Solar Cooker cum Dryer

Abstract

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 solar cooker cum dryer was designed, developed and fabricated. The performance evaluation of the system was carried out. The solar cooker was used as the solar collector for the solar dryer. A solar cooker having size 750mm x 600mm x 150mm has been developed. The solar dryer was designed with 0.49 m2 collector area. The collector angle was calculated for Jalgaon and it is 24.16˚ facing south. Drying chamber of size 750mm x 600mm x 450mm was designed and fabricated. This equipment was tested for cooking of food materials. The various atmospheric and drying parameters were also observed during the testing
