Drying kinetics and equilibrium moisture content of MDF fibres
Journal article, 2009

An experimental device was constructed to study the drying kinetics of wood fibers under controlled conditions. The device consisted of a drying chamber in which a net basket filled with the fiber material was connected to a load cell. The drying medium was then forced through the basket at controlled levels of humidity and temperature. Experiments were performed with spruce fibers and the drying medium at varying temperature (50-170° C) and relative humidity (1-86%). In general, the drying rate increased with increasing temperature and decreasing relative humidity. A constant drying rate period was observed in all cases. The critical moisture content was approximately 1.25. The characteristic drying curve has a slight downward concave shape. The equilibrium moisture contents obtained at ambient temperature agree well with data in the literature. © 2009 Taylor & Francis Group, LLC.
