STERILIZATION SYSTEM FOR A BLOW/FILL/SEAL MACHINE |
| 摘要 |
A fill assembly sterilization system for a blow/fill/seal machine utilizes a closed loop circulation of sterilant containing gas. A typical sterilant is nitrogen dioxide. The closed loop includes a shroud that defines a plenum and encloses the fill system. Optionally, at least one high efficiency particulate absorption (HEPA) filter is provided in the closed loop. Sterility assurance level of 10−6 can be achieved by subjecting the fill system to the sterilizing gas for at least 20 minutes at a temperature in the range of about 18° C. to about 30° C. |

1. A sterilization system for a blow/fill/seal machine having a fill assembly, and comprising
a shroud enclosing the fill assembly and defining a plenum, a sterilizing gas inlet and a sterilizing gas outlet; an external conduit defining at least one sterilizing gas flow passageway between said sterilizing gas inlet and said sterilizing gas outlet; a blower in the external conduit adjacent to said sterilizing gas inlet for circulating the sterilizing gas through the shroud; and a sterilizing gas source in confined flow communication with the blower. |
