Vacuum chambers of the plant are complemented with steam ejectors connected to the steam generator, and their suction line is connected to an adjacent chamber, and heaters installed inside act as condensers of steam used by ejectors. Using steam ejectors makes it possible to simultaneously vacuumise in one chamber and heat in the other one. Besides, the thermal energy removed at the vacuumisation stage from one chamber is sent to heat saw timber in the other chamber.

EFFECT: reduction of prime cost of saw timber drying process, formation of steam in the steam generator may take place by combustion of wood waste generated in production.
