Modélisation de la déshydratation de la pulpe des fruits du Canarium schweinfurthii Engl

Modelling of the Dehydration of Canarium schweinfurthii Engl. Fruit Pulp. In this work, we obtained drying kinetic of Canarium schweinfurthii Engl. pulp fruit, under conditions of air velocity ranging between 1 and 3 m/s, relative humidity between 40 and 60%, temperature between 40 and 70 °C. The experiments were made in drying tunnel where properties of hot air flow are determined and controlled. It is observed from the drying kinetics that there is no constant rate phase. Modelling of the results was performed using the caracteristic curve of drying. Futhermore, we determined aiele pulp desorption isotherms in differents temperatures (40, 50, 60 and 70 °C), the Guggenheim, Anderson and de Boer model proved to be satisfactory to describe them.
