microwave drying). The described microwave vacuum technology is used for high-end drying applications of thermal sensitive products like fruits and vegetables in order to achieve higher product qualities and shorter drying times. cDepartment of Mechanical Engineering, National University of Singapore, 9 Engineering Drive, Singapore 117576, Singapore Microwave (MW)-related (MW-assisted or MW-enhanced) combination drying is a rapid dehydration technique that can be applied to specic foods, particularly to fruits and veg-etables. About 100% of these are fruit & vegetable processing machines. Keywords: Dehydration, Solar dryer, tunnel dryer, tray dryer. Especially in microwave vacuum drying this advantages has a big significance for bulk products with poor thermal conductivity. Fruits and vegetables selected for drying should be the highest quality Top, enclosed frame solar drying oven with provision for air movement. 7 DIY Solar Dehydrators You Can Make at Home! the orientation of fibres in vegetables DEHYDRATION OF FRUITS AND VEGETABLES USING SOLAR ENERGY By S. C. Gupta Department of Agricultural Engineering, Allahabad Agricultural Institute, Allahabad, U.P., India ABSTRACT Most fruits and vegetables do not re quire very stringent drying conditions and solar energy, in the form of heat, can be effectively utilized for their As you reach the end of the drying time, check your fruits and vegetables frequently for dryness. Fruit and vegetables that are inferior before drying will be inferior after drying. Dehydration is the most common processing method or step, but also is the most energy consuming step in food and agricultural product processing. 357 Solar drying of fruit and vegetables.
