Bark openings or slots () extend through the drum inner surface () and multiple rigid studs () protrude inwardly from the inner surface () and are positioned between the debarking iron sections (). The studs operate to break the bark () of the wood () for debarking. The studs () are positioned along a partial length (L) of the drum () between the first end () and the second end (). The invention also relates to a method and system for the debarking of wood by the debarking drum.
