Convective, microwave and microwave-convective drying and mathematical modeling of apricot (Prunus armeniaca L.)

33993

In this study, the effects of convective (50 and 75 °C), microwave (90 and 160W) and microwaveconvective (90W-50 °C, 90W-75 °C, 160W-50°C and 160W-75 °C) drying treatments on the drying parameters of apricot samples were investigated. To select the best thin-layer drying models for the drying treatments, 9 mathematical models were fitted to the experimental data and the performances of these models were compared for the following statistical parameters: reduced chi-squared (χ^2), root mean square error (RMSE) and coefficient of determination (R^2). Among the drying models investigated, the Midilli et al. model was found to be the best model for describing the drying behavior of apricot samples. The experimental results showed that increasing the drying temperature or microwave power level caused shorter drying time and the combined microwave-convective method provided the greatest time savings in comparison to other methods tested.
