MODELLING EFFECTIVE MOISTURE DIFFUSIVITY OF BERGAMOT SLICE (Citrus Medica)

摘要：

In this study, the drying behaviour of bergamot was fitted with the Page model with temperature dependence (40, 50, 60, 70 and 80oC), wheras the air velocitiy was at 2 m/s.The effective diffusivities (Deff) of bergamot were found to be 1.91×10-9, 2.23×10-9, 3.08×10-9, 3.80×10-9 and 4.15×10-9 m2/s at 40, 50, 60, 70 and 80℃ respectively.Therefore, it can be concluded that the effective diffusivity increases with air temperature.The activation energy (E a ) for diffusion and The diffusivity constant (D 0 ) were calculated and were 17319 J/g mol and 1.86×10-6 m2/s.During the falling drying rate, Deff is the main process that controls drying.
