Modelling the drying of a twig of "yerba maté" considering as a composite material Part II: Mathematical model
A drying model was developed for a composite material using the finite-difference method and applied to drying of twigs of "yerba maté". Drying experiments were carried out in a convective dryer with twigs with and without bark for three different diameters: 2.5 × 10-3, 5.0 × 10-3 and 7.5×...
