PINHEIRO, P. C. C.; RAAD, T. J.  and  YOSHIDA, M. I.. MODEL OF A PROCESS FOR DRYING Eucalyptus spp AT HIGH TEMPERATURES. Braz. J. Chem. Eng. [online]. 1998, vol.15, n.4, pp. 382-395. ISSN 0104-6632.  http://dx.doi.org/10.1590/S0104-66321998000400007.

A mathematical model of a process for drying of Eucalyptus spp is presented. This model was based on fundamental heat and mass transfer equations and it was numerically solved using a segregated finite volume method. Software in the FORTRAN language was developed to solve the mathematical model. The kinetic parameters of drying for Eucalyptus spp were experimentally obtained by isothermal thermogravimetry (TG). The theoretical results generated using the mathematical model were validated by experimental data.
