Design and Fabrication of Raisin dryer using Solar Powered Air Blower

This project describes the drying of grapes using a solar powered air blower and a heating module (peltier chip) .The preparation and maintenance of grapes has been considered to be a major complex issue for a long time. In order to achieve more product and higher marks and achieve customer satisfaction more attention is given to quality features. Quality factors including color, size, taste were very important as they would differ from the dehydration process. This project is used to reduce drying time by using solar energy. Solar power plants are important in the tropics, which face challenges in accessing electricity, which severely limits the refrigeration usage as storage of agricultural products is limited, and the need to make products competitive overseas. In this project, the solar energy used to dry food is described; it is thought that hot weather conditions are favorable during the summer season. A DC drive for suction fan operation is used to send atmospheric air into the system and the air temperature is increased using a peltier chip placed in the air. DC’s utility system is powered by a battery charged with the help of solar panels and electricity supply. It works well that the design will be able to shorten the final product time rather than the traditional method.
