ABSTRACT:
An autoclave 10 has a first vessel 12 in which objects are heated, and a second vessel 14 in which the objects are cooled down. A container 24 containing the objects is introduced via a preheating chamber 30 into a chamber 20, and thence into the cavity 16 of the vessel 12. Similarly, at the downstream end of the second vessel 14, a container is removed from a cavity 18 via a chamber 22. Transfer of containers is effected in a manner similar to operation of a lock to limit loss of pressure. When a container is thus removed and a fresh container is loaded, containers in the cavity 16 are advanced upwardly and containers in the cavity 18 are advanced downwardly. A container at the top of the cavity 16 is laterally displaced to the top of the cavity 18, via a chamber 19. The autoclave is thus operated continuously, stepwise. Pressures and temperatures are monitored via an interface 32 and a computer 34. Sterilization values for the objects are computed and advance of the containers are dependant on appropriate sterilization values being obtained.
