The objective of this work was to determine and model kinetic drying of leaves of Capparis Spinosa. Leaves were dehydratated in an oven until constant mass. The applied temperatures were 40°C, 50°C and 60°C. The results show that drying curves of leaves of Capparis Spinosa do not present a constant period. The effctive diffusivity of leaves of Capparis Spinosa varied between 1,09×10-11 and 1,82×10-11 m2/s in the rage of 40°C to 60°C. Curve expert software was used to find the best model for evaluating the rate of change of moisture change. Among the tested models, Logarithmic and Page models fitted the best the experimental results.

Abstract: (french)
L’objectif de cette étude est la détermination et la modélisation de la cinétique de séchage des feuilles du Capparis Spinosa; Les feuilles ont été déshydratées jusqu'à une masse constante dans une étuve. Les températures de séchage sont : 40,50 et 60°C. Les résultats montrent que les courbes de séchage des feuilles de Capparis Spinosa ne présentent pas une phase de cinétique constante. Les coefficients de diffusion varient entre 1,09×10-11 m2/s et 1,82×10-11 m2/s dans l’intervalle de 40°C et 60°C. Curve expert est utilisé pour trouver le meilleur modèle qui lisse la variation de l’humidité modèle. Parmi les modèles testés, le modèle logarithmique et le modèle de Page décrivent le mieux les courbes caractéristiques de séchage trouvées expérimentalement.
