Drying of Tunisian sardine (Sardinella aurita) experimental study and three-dimensional transfer modeling of drying kinetics

摘要: Abstract Experimental drying curves of sardine muscles ( Sardinella aurita ) in parallelepiped form were performed under different air conditions (three temperatures: 35, 40 and 50 °C ± 1 °C, two velocities: 1 2.5 m s −1 , at atmosphere humidity). A diffusive three-dimensional model was established to describe sample form. The calculated compared the experimental ones order determine apparent moisture diffusivity. An empirical equation describing diffusivity within suggested versus temperature local content product. good agreement found between kinetics.
