Combined Microwave Fan-Assisted Convection Dehydration of Banana [Musa acuminata Colla (Cavendish Group)]

摘要

The effects of microwave drying, combined fan-assisted convection and microwave drying, and fan-assisted convection drying, thickness of sample and mass load of sample on drying time and drying ratio capacities of banana [Musa acuminata Colla (Cavendish Group)] were compared. The drying data were applied to nine different mathematical models, namely, Newton, Page, Henderson and Pabis, Logarithmic, Diffusion Approach, Wang and Singh, Verma, Two-Term Exponential and Midilli-Kucuk Equation Models. The performances of these models were compared between the observed and the predicted moisture ratios based on coefficient of determination (R~2), standard error of estimate (SEE) and residual sum of squares (RSS). We found that the Midilli-Kucuk model described the drying ratio satisfactorily in all drying methods.
