Abstract :
Abstract: In this research, microwave drying characteristics on moisture ratio, drying rate of quince slices were reported. Quince slices were dehydrated in a fan assisted microwave oven dryer. The effects of microwave drying (180, 360, 540, 720 and 900W) on drying time, drying rate of quince slices have been investigated. Quince slices were dried from 3.75 g water/g dry matter initial moisture content to 0.12 g water/g dry matter final moisture content. In the microwave drying system, quinces sliced into 5 mm thickness were dried at 180, 360, 540, 720 and 900W microwave drying powers. During microwave drying experiments, slices were weighted and data recorded manually per 1 minute. The drying data were applied to nine different mathematical models, namely, Newton, Page, Henderson and Pabis, Logarithmic, Midilli-Kucuk, Wang and Singh, Two Term, Verma, Two Term Exponential, Diffusion Approach Equation Models. It was found that the Midilli-Kucuk model described the drying curve satisfactorily in all drying methods.
