Wood Drying Basics
The water inside wood moves from a higher to a lower zone of moisture content.
In other words, “wood dries from the outside in.” This means that the surface of the wood must be drier than the interior if moisture is to be removed.
The drying process can be broken down into two phases:
1. The movement of water from the interior towards the surface of the wood.
2. The removal of water from the surface.
The water inside wood is held as free water and bound water. Free water is contained inside the cell cavities, and bound water is held within the cell walls. Free water within the cell cavities is held less tightly than bound water within the cell walls. Consequently, slightly more energy is required to remove bound water than free water. Free water does not affect as many wood properties as bound water. The removal of bound water affects many physical and mechanical properties and therefore affects the quality and use of the wood.
The fibre saturation point (FSP) is defined as the moisture content at which “free water is completely gone, while the cell walls are saturated with bound water”. In most types of woods, the fibre saturation point is roughly at 25 to 30% of moisture content.
