MACHINE FOR WOOD DRYING Russian patent published in 2009 - IPC F26B9/06 F26B5/04 

FIELD: heating.

SUBSTANCE: machine for wood drying contains cylindrical pressurised body with installed inside heaters, ventilator and longitudinal partitions which form aerodynamic tract of movement, vacuum-pump, steam-generator and cargo cart for placing wood which is to be dried inside the chamber. Installation is provided with second pressurized chamber partially filled with liquid (water) and connected with the first chamber by means of pipe with perforated attachment on the tip for pressure "drop" and with two lines of condensation equipment, compressor of one of which is connected with heaters of the first chamber and condenser of the second chamber, and compressor of the second line is connected with heaters of the second chamber and condenser of the first chamber; in addition, inside the first chamber additional electric heater is installed. By means of condensation equipment heat energy removed from the first chamber, in which process of vacuumisation takes place, is brought to the second chamber in which heating of liquid (water) takes place; after the end of cycle "heating-vacuumisation" by switching off one compression device and switching on another change of stages in chambers takes place: in the first chamber heating of saw timber starts, and in the second necessary vacuum for further pressure drop is created.

EFFECT: reduction of cost price of saw timber drying process.
