METHOD FOR DRYING OF SAW TIMBER Russian patent published in 2010 - IPC F26B3/04 F26B5/04 

FIELD: heating.

SUBSTANCE: substance of method for saw timber drying, including delivery of saw timber into drying chamber, heating of drying agent in heating volume, displacement of drying agent in drying volume through saw timber with the help of fan, with the possibility to change direction of drying agent motion, drying of drying agent in condensation volume with condensation of water vapours in heater, sunction of spent drying agent by vacuum pump with vacuum development in drying chamber, moistening of saw timber in process of drying, control of drying process in automatic mode by means of microprocessor unit according to specified program. Even movement of drying agent in drying volume through saw timber is maintained by periodical calibrating inspection of gaskets height diminishing, those with allowance of more than 1 mm are rejected, installation of gaskets of identical height in all packs of drying chamber, for instance 25 mm high, coolant in working drying chambers is represented by hot water supplied by heating networks from biological boiler house of woodworking plant that operates on biological fuel of its own production wastes: bark, collected under the table for log processing line, bark produced at the first stage of bark stripping, woodchips.

EFFECT: reduced power inputs and recycling of production wastes.
