Timber is traditionally dried in kilns by processes that often take several days or weeks to complete. At present, it is possible to apply several methods of rapid drying of timber, including, for example, press drying. This research is based on the use of this process. Drying was performed using the heating plates with a temperature of 160 °C. Three pressures were compared in the research 1.0 MPa, 1.4 MPa, and 1.8 MPa. The density of the samples remarkably increased during press drying. The pressure of the heating plates had a substantial effect. The difference in the average density between the pressure of 1.0 MPa and 1.8 MPa was more than 92 kg.m-3 . A larger increase in density was discovered for radial samples (ranging between +95.31 to+110.85). The difference in the change of sample thickness was larger in the case of the tangential samples. For both groups of samples (radial, tangential) and all ressures, the samples dried by the contact method were more stable during swelling than the samples dried by the convection method.
