This process was revisited through the modified Peleg model, assuming the drying as a moisture desorption versus drying time. The leaves of <em>Corymbia citriodora</em> acclimatized in the Congo Brazzaville “Plateau des Cataractes” were dried in open air and under shade thanks to a domestic scale of essential oil production. One obtains&nbsp; following model parameters: kinetic constant k<sub>1</sub>: 0.8555 - 2.1355 d.(g/g)<sup>-1</sup>, extraction capacity constant K<sub>2</sub>: 1.5255 - 1.8733 (g/g)<sup>-1</sup>; end equilibrium moisture X<sub>∞</sub> = 0.53 - 0.66 g/g. and first order&nbsp; drying kinetic constant k = K<sub>2</sub>/k<sub>1</sub>: 1.71 - 1.78 d<sup>-1</sup>. Pseudo first order diffusion model fits experimental data with k = 0.368 - 0.587 d<sup>-1</sup> and t<sub>1/2</sub> = 1,18 - 1,88 d.<strong><em>. </em></strong>These results needed for the optimization of proccess and sizing equipments came from a fast graphic data processing, with low computer inputs.</p> ER -
