Abstract

The objective of this study was to assess, whether it is possible to reduce and to level out cross sectional wood moisture contents in thin beech timber through mechanical wood demoistening, i. e. a regime of alternating atmospheric high and ambient pressure. For this purpose, 25 pieces of beech timber of up to 30 cm mid diameter and 2.80 m length were treated in a pressure chamber. Their wood moisture content and cross sectional wood moisture distribution were compared to 26 untreated controls. The treated beech timber had significantly lower wood moisture contents as compared to untreated controls. Furthermore, wood moisture was significantly more evenly distributed across the trunks. Neither untreated controls nor treated samples had noticeable wood moisture gradients from the stem periphery to the centre. Instead, wood moisture was distributed irregularly across the trunks.
