Modelación fenomenólogica de las curvas de sec ado por alta temperatura de pino radiata

Abstract

Experiments at industrial scale to show the high temperature wood drying of radiate pine were performed. After that, physical parameters of transport phenomena (global heat and mass transfer coefficients), required by the phenomenological mathematical models for the simulation of the drying process, were determined. Results of global heat transfer coefficients, experimental drying curves and simulated process were shown. It was concluded that the simulation of the drying process at high temperature of radiata pine can be satisfactorily carried out by phenomenological model based on the global mass transfer coefficient. The values of these coefficients were between 1 ́ 10-4 and 4.2 × 104 kg/m2s.
