SHAPED TIMBER DRYING METHOD Russian patent published in 2009 - IPC F26B5/04

Abstract RU 2349849 C1

FIELD: construction industry; heating systems.

SUBSTANCE: shaped timber is heated in vacuum drying chamber, for example by being arranged between rows of heating elements - flexible mats or stiffened slabs - in four-stage modes with the stiffness changing parabolically following the condition (t₁, P₁)>(t₂, P₂)<(t₃, P₃)<(t₄, P₄), where: t_i - staged material temperature, °C; P_i - vacuum pressure, kPa; at that timber temperature is kept approximately at water boiling level at the appropriate pressure.

EFFECT: high quality of shaped timber drying, and reduction of electric energy consumption.
