ABSTRACT
This study is related to drying of wood chips as a preconditioning step for wood pellet production. This article presents experimental data which are important in designing an industrial drying process: initial moisture content, bulk density, bulk porosity and desorption isotherm. Five wood species from the boreal forest have been investigated and two initial hydric states were considered, i.e. green state and pre-dried state. Desorption isotherms have been modelled using the GAB model, whose constants have been determined using a linearization method.
