DRYING CHAMBER Russian patent published in 2004 - IPC

FIELD: wood processing equipment.

SUBSTANCE: proposed drying chamber has hermetic bath whose body is sectional in form with external and internal walls and heat insulation layer in between them; bath is provided with hinged cover. Heat insulation layer ensures maintenance of optimal temperature conditions inside bath where working reservoir with wood laid on screens made from steel strips is located. Wood is pressed by means of hold-down frame and springs. Additional reservoir for storage of working heat-transfer agent (paraffin) is placed in bath and is brought in communication with main working chamber. Heating system includes heat exchanger with external heat-transfer agent; tubes of this heat exchanger are laid on bottoms of working and additional reservoirs. Working reservoir is provided with set of fans which are used for exhaust of vapor-gas mixture, ventilation and steaming of wood.

EFFECT: reduction of labor consumption; facilitated drying at removal of internal stresses and preservation of wood quality and moisture content.
