Abstract. The paper considers the convective drying of softwood lumber at the continuous circulation of a drying agent under low pressure.

29 июн. 2021 г. · The damp air is replaced with new drier air, i.e. air with a lower vapour pressure better able to absorb further moisture from the wood. ...

The traditional rule-of-thumb for air-drying lumber is to allow one year of drying time per inch of wood thickness.

7 дек. 2023 г. · For most woodworking purposes, the desired moisture content is generally between 6% and 8%, depending on the intended use.

In this method lumber is dried at a pressure above one atmosphere and a temperature above 212°F. In this paper we discuss the principles of steam drying lumber, ...

It has cut drying time from several weeks to only 4 days. As the drying process progresses, the pressure that works in the chamber is also reduced. Using steam ...

The high pressure steam goes through a turbine which rotates an axis connected to an electric generator. On the other hand the waste steam or low pressure steam ...
