Verfahren zum Sterilisieren einer Füllmaschine.

摘要

A sterilizing method is provided for use with a container filling machine (200) having components defining passages through which a fluid product flows. In one method aspect, sterilizing steam is passed through the components until the components have been sterilized. As the system cools and the steam condenses, the system is pressurized with gas to prevent the internal pressure in the system from decreasing below the ambient atmospheric pressure. In a further method aspect, the sterilizing process is controlled in response to sensing the temperature of one or more of the components. In yet another aspect, a common source of sterilizing steam (242) is provided for being directed into the product filling system (216) and simultaneously into an associated process gas supply system (224) to sterilize both systems generally concurrently in a single pass.
