Design and Fabrication of Food Dryer

Abstract

Pakistan has two major national strengths; the high rate of agricultural production and the solar irradiance that graces most of the country year-round. This project attempts to combine the two with a complementary technology that would enable Pakistani food products to compete internationally by both improving quality and cutting costs. Microwave drying with Convection has been proven in literature to be a highly efficient method of drying food items. Microwave convective drying (MCD) is achieving growing interest for its distinctive volumetrically heating capability and ability to considerably cut back drying time and improve food quality. Long drying time may be a concern in food industries. We are innovating the system by carrying out the drying operation in a highly dehumidified environment which both in theory and practice, results in improvement in all desired control parameters.
