An arrangement for feeding wood particles into an impregnating stage of a wood treatment process comprises a feed silo (301, 701), at least one impregnating vessel (305, 601, 602, 603, 703) for receiving wood particles into said impregnating stage, and two or more conveyors (302, 303, 304, 501, 502, 503, 702) between said feed silo (301, 701) and said at least one impregnating vessel (305, 601, 602, 603, 703), for transferring wood particles from said feed silo (301, 701) to said at least one impregnating vessel (305, 601, 602, 603, 703). Each of said conveyors (302, 303, 304, 501, 502, 503, 702) is a compressing conveyor for applying pressure to the wood particles on their way through the respective conveyor.
