ABSTRACT:
A method for the sterilization of a machine used in the formation, filling and sealing of plastic containers. A source of sterilizing agent, such as steam, is used to sterilize the various passageways, filters, and components within the machine which, if contaminated, would contaminate the liquid in the filled plastic container. Pressurized air or gas is delivered through sterilized lines having a micro-organism filter. The air flowing out of each filter is sterile and free from bacteria. A series of unique, easy to sterilize, three-position, two-way valves are used to duct pressurized gas and steam to the various components. A special air drop test apparatus is used to operationally check the integrity of the filters without breaching the sterile condition of the various fluid passageways and interconnected components.
