The impact of air velocity and temperature on the drying curves of the invasive brown alga Sargassum muticum was evaluated. An air impingement dryer was applied at five air velocities and four air temperatures. The equilibrium moisture content was properly modeled by Oswin, Halsey, and GAB models. Fick's diffusional model was employed to identify the apparent moisture diffusivity. The variations of the diffusivity versus temperature and velocity were determined. Three semi‐empirical expressions, namely, Page, two‐term, and Henderson‐Pabis modified equations were selected to fit the drying kinetics. The two‐term equation was the most appropriate to model the experimental data.
