Hygro-thermal modification of solid wood.
Abstract
Lack of knowledge about undesirable discolorations of hardwoods during storage and drying/steaming process, respectively, lead to processes of considerable quality and value losses. Currently, the potential of achieving a defined and even color of solid wood is restricted. The technology of drying and steaming in linkage with developments in technology has to be reconsidered and modelled in a new way to achieve an efficient consumption of resources and cost savings. The drying/steaming schedules, which developed mostly by experience, have to be critically determined, and the procedures of discoloration need to be revealed in their basic phenomena. The next step is the establishment of models based on “experimental design”, applying methods that lead to a knowledge-based production for wood drying and steaming.
