Line for drying raw wood and timber. The heat treatment of the wood before processing is good for reducing wood moisture to the so-called functional moisture.

In addition drying can reduce later shrinkage and swelling of the wood significantly.

Types of drying kilns and function

Longitudinal timber dryer and transversal ventilated dryer

The most used procedure is the intake/outlet air drying. Here the air heated up in a heating register is blown through the drying kilns by means of fans.

HF - vacuum- drying kilns

HF-Vacuum-drying kilns use electrical alternating fields for the vaporization of wood humidity and vacuum technology for conveying water vapour.

Vacuum drying kilns

When vacuum drying, the wood is being subjected to underpressure in addition to the warm airflow around. This speeds up the process of evaporating water contained within the wood and thus ensures careful drying.

Other drying plants

For drying varnished workpieces drying kilns are not suitable! Here lacquer drying systems are used.
