Title:
WOOD DRYING METHOD
Document Type and Number:
WIPO Patent Application WO/2004/099692
Kind Code:
A1
Abstract:
The invention relate to wood processing engineering, in particular to sawn timber drying process, including thick-walled and round logs, with the aid of vacuum-impulse action performed on timber arranged in sealed drying chambers. The inventive method for drying thick-walled timber and logs consists in supplying steam to said drying chambers (1, 2), equalising humidity along the cross section of said sawn timber (28) inside and outside thereof and in heating the timber. Said operations are carried out with the aid of air ducts (23, 24) circled by sections, fans (20), distributors (24), air heaters (21) and guiding elements (25, 26,27) which uniformly distribute a flow through the height and length of stacked sawn timber (28). The distribution of steam and a wood syrup saturated steam-air mixture is carried out in two operations i.e. at first, in diffusers arranged between the fans (20) and the air heaters (21) and, afterwards with the aid of the guiding elements (25, 26,27) on at least two levels. The inventive method for drying thick-walled timber, i.e. beams, logs etc makes it possible to avoid the occurrence of stresses, cracks or warping of wood.
