چکیده انگلیسی
Thermophysical properties and hygroscopic behavior of unripe banana (Musa cavendishii) were studied. The sorption isotherms were measured at 25 °C, 40 °C, 50 °C and 60 °C and the observed sigmoid curves were modeled with GAB equation which satisfactorily fitted the experimental data. The mean value of monolayer moisture content (Xm) estimated was (5.5 ± 0.6) g/100 g d.b. Drying experiments were conducted at temperatures of 40 °C, 50 °C and 60 °C and the apparent density, specific heat, thermal conductivity and thermal diffusivity - were directly measured as a function of moisture content and porosity. Empirical models obtained by nonlinear regression were successfully fitted to the thermophysical properties, important data to model and simulate the drying process.
