Method and device for drying, modelling and/or thermally modifying wooden parts

A method for heat treatment of wooden parts by transmitting heat to wooden parts in a low-oxygen environment, comprising the steps of:

• a) arranging the wooden parts in a bath;
• b) filling the bath with a liquid;
• c) the liquid being heated for some time for the purpose of drying or thermally modifying the wooden parts;
• d) removing the wooden parts from the bath;
• wherein,
• step a) comprises the sub-steps of:
• a1) placing a liquid-excluding covering with an open underside of heat-conducting solid material over the wooden parts;
• a2) holding the covering in position during steps b), c) and (d);
• and
• step b) comprises the sub-step of:
• b1) enclosing the open underside of the covering with the liquid thereby creating a liquid level under the covering that encloses a volume of air under the covering, whereby the volume of air is contained under the covering by the liquid and the covering such that an air pressure is created under the covering which ensures that contact between the liquid and the wooden parts is avoided during steps b), c) and d).
