METHOD TO DETECT DEMAND OF DRYING AIR IN WOOD DRYERS Russian patent published in 2012 - IPC F26B3/04 F26B25/22 

FIELD: power engineering.

SUBSTANCE: wood in the form of a wood pack is placed into a drying chamber closed relative to the environment, and where the water-containing atmosphere with moist temperature, dry temperature and a related psychrometric difference are maintained with the help of an injected drying air sent via wood. To optimise power consumption in process of drying, the speed of supplied drying air is controlled depending on current moisture in the wood or by registration of lower water release from the wood; at the same time control of current moisture or start of water release drop is carried out by measurements performed in process of drying.

EFFECT: reduced energy intensity of the process.
