Apparatus is disclosed for steam drying a cake of filtered solids formed on a disc filter element of a rotary disc vacuum filter where the disc filter element is mounted on a rotating means for rotation in a container, the lower portion of which includes a slurry tank and the upper portion of which includes a steam hood. The steam hood encloses a portion of the disc filter element in a steam chamber and includes a pair of sidewalls and a spine wall which joins the pair of sidewalls. A linear seal means is mounted to the pair of sidewalls of the hood to define a steam-retaining exit for the steam chamber through which the disc filter element rotatably moves, and includes two elongated flexible flaps which extend in a straight line from the spine wall into the slurry tank.
