Fitting of mathematical models in the drying of araticum (Annona crassiflora) seeds

Araticum (Annona crassiflora) seeds have relevant characteristics for industrialization due to the contents of phytosterols, carotenoids, phenolic compounds, fatty acids, and organic among other components responsible biological properties. The objective this study was fit different mathematical models experimental data, use criteria choose best model, evaluate effective diffusion coefficient, obtain activation energy thermodynamic properties araticum at drying temperatures. Seeds fruits were dried temperatures 40, 50, 60, 70ºC. time seed decreases with increasing temperature. Among fitted, Midilli model recommended predict curves under conditions. linear represented coefficient as a function Enthalpy entropy tend reduce, Gibbs free increases temperature increases.
