A multichamber timber drying kiln in which different conditions are maintained in each chamber and methods of drying timber using such a kiln. In one aspect timber is rapidly heated within a first chamber ( 2; 202; 207 ) and then transferred to a further chamber ( 3; 203; 208 ) for further drying. Timber may be transferred from the first chamber ( 2; 202; 207 ) when the moisture content of the timber approaches the fibre saturation point A preheating chamber ( 1; 201; 206 ) may be provided to preheat the timber before passing to the first chamber ( 2; 202; 207 ). A conditioning chamber ( 4; 204; 209 ) may be provided after the further chamber ( 3; 203; 208 ) to condition the timber. Energy transfer means ( 49-53; 54-58 ) may be provided to transfer energy between chambers. |
