The article presents the results of experimental and computational studies of the kinetics of drying of different types of wood in a helium environment. Wood is considered as a multi-component composite, one component of which is free and bound moisture. A model describing the removal of bound moisture, as a set of direct (desorption) and reverse (sorption) processes is described. The experimental-computational method for determining the kinetic parameters of sorption is suggested. They are determined from the condition that the rate of sorption and desorption is equal with equilibrium moisture content of wood.
