<p>The present invention relates to a process for reducing water content in wood material, which process comprises the steps of:
- feeding said wood material into an overheated vapour filled, oxygen free drying apparatus (1),
- indirectly overheating said vapour in said drying apparatus (1) by heating means (3), whereby water and other chemical substances vaporise from said wood material into the atmosphere within the drying apparatus (1),
- releasing surplus drying apparatus vapour into separation means (2) which are connected to said drying apparatus (1), and
- discharging the dried wood material from said drying apparatus (1) when the moisture content in the wood material has reached a level of less than 10 % by weight.
The present invention also relates to wood material drying means to be used in said process.</p> |
