A mathematical model of heat and mass transfer in vacuum-oscillating 
drying of lumber in which the drying process is made up of alternating 
stages of warming up and vacuum treatment has been developed. At the 
stage of warming up, it has been proposed to use a superheated steam 
to intensify heat- and mass-transfer processes and to relax stresses 
occurring at the stage of vacuum treatment.
