ABSTRACT A vertical container holds and treats particulate material, such as comminuted cellulosic fibrous material like wood chips. The container in- cludes a vertical interior wall, an open top, and a discharge outlet at the bottom. A top interior wall structure directs particulate material to a first false bottom concentric with it. The first false bottom is mounted for oscillation with respect to the vertical container and discharges particulate material through a discharge opening in the generally conical bottom thereof into a second false bottom structure. The second false bottom structure also includes a generally conical bottom with a discharge opening, and is also mounted for oscillation with respect to the container. Steam is preferably introduced into the container to effect steaming of the particulate material within it, and the container is held at super-atmospheric pressure.
