ABSTRACT:
There is described herein an improved method for decatizing in an autoclave wherein steam is led into the jacket surrounding said autoclave, at a pressure level increasing up to a stationary level within the autoclave. That is obtained by means of an automatically and adjustably controlled throttling valve at the steam inlet to the jacket, the valve being for instance driven by means of a microprocessor routine, and having an autoclave inlet valve associated therewith. In case the outer jacket is missing there might possibly be provided only an automatically controlled autoclave inlet valve performing also as a throttling valve, in order to have a gradually increasing inlet pressure.
