ABSTRACT:
In an autoclave (1) which can be charged with bulk material and has at its bottom a discharge opening (2) to be closed by means of a cover (4), the cover (4) can be opened inward. For preventing that the bulk material obstructs the opening movement of the cover (4), a closure device (13) is provided to shut off the cross-section of the autoclave, said closure device being opened only after the cover (4) closing the discharge opening (2) has started its opening movement. The preceding closure device (13) comprises downwardly swivellable plates (12).
