Abstract

Provided is an aseptic filler that includes no other sterilization apparatus for producing aseptic water than a sterilization apparatus for sterilizing a content, and a method for cleaning the same.
An aseptic water supply apparatus that supplies aseptic water, which is sterilized by a content sterilization apparatus that sterilizes a content, to at least a filling portion chamber is provided, and rinsing aseptic water for washing away a sterilizer when performing an SOP treatment of each chamber is supplied to each chamber.

First claim

The invention claimed is:

1. An aseptic filler, sequentially comprising:
a container sterilizing portion that sterilizes a molded container;
an air rinsing portion that air rinses the sterilized container;
a filling portion that fills the container sterilized with an aseptic atmosphere, with a content sterilized by a content sterilization apparatus;
a sealing portion that seals the container filled with the content, with a sterilized lid material in an aseptic atmosphere;
a discharging portion that places the sealed container on a discharging conveyor; and
further comprises chambers that shield the container sterilizing portion, the air rinsing portion, the filling portion chamber and the discharging portion,
wherein the aseptic filler comprises an aseptic water supply apparatus that supplies aseptic water which is sterilized by the content sterilization apparatus and sprays to a container sterilizing portion chamber, an air rinsing portion chamber, a filling portion chamber and the discharging portion chamber of the aseptic filler.

2. The aseptic filler according to claim 1 , wherein the aseptic water supply apparatus includes a heating apparatus that heats the aseptic water.

3. The aseptic filler according to claim 2 ,
wherein the aseptic water supply apparatus includes a sterilization apparatus that sterilizes an interior of aseptic water supply piping for supplying the aseptic water from the content sterilization apparatus to at least the filling portion chamber.

4. The aseptic filler according to claim 2 ,
wherein two or more of the content sterilization apparatuses are provided.

5. The aseptic filler according to claim 2 ,
wherein the aseptic water supply apparatus is provided with an aseptic water reservoir tank that stores the aseptic water.

6. The aseptic filler according to claim 1 , wherein
the aseptic water supply apparatus includes a sterilization apparatus that sterilizes an interior of aseptic water supply piping for supplying the aseptic water from the content sterilization apparatus to at least the filling portion chamber.

7. The aseptic filler according to claim 6 ,
wherein two or more of the content sterilization apparatuses are provided.

8. The aseptic filler according to claim 6 ,
wherein the aseptic water supply apparatus is provided with an aseptic water reservoir tank that stores the aseptic water.

9. The aseptic filler according to claim 1 , wherein two or more of the content sterilization apparatuses are provided.

10. The aseptic filler according to claim 9 ,
wherein the aseptic water supply apparatus is provided with an aseptic water reservoir tank that stores the aseptic water.

11. The aseptic filler according to claim 1 , wherein the aseptic water supply apparatus is provided with an aseptic water reservoir tank that stores the aseptic water.

12. A method for cleaning an aseptic filler,
the aseptic filler sequentially including: a container sterilizing portion that sterilizes a molded container; an air rinsing portion that air rinses the sterilized container; a filling portion that fills the container sterilized with an aseptic atmosphere, with a content sterilized by a content sterilization apparatus; and a sealing portion that seals the container filled with the content, with a sterilized lid material in an aseptic atmosphere; a discharging portion that places the sealed container on a discharging conveyor; and
further includes chambers that shield the container sterilizing portion, the air rinsing portion, the filling portion and the discharging portion,
wherein interiors of a container sterilizing portion chamber, an air rinsing portion chamber, a filling portion chamber and a discharging portion chamber are cleaned by supplying and spraying aseptic water sterilized by the content sterilization apparatus.

13. The method for cleaning an aseptic filler according to claim 12 ,
wherein the aseptic water supplied from the aseptic water supply apparatus is heated.

14. The method for cleaning an aseptic filler according to claim 13 ,
wherein the interior of aseptic water supply piping, which supplies the aseptic water from the content sterilization apparatus to at least the filling portion chamber, is sterilized with a sterilizer.

15. The method for cleaning an aseptic filler according to claim 13 ,
wherein the aseptic water is supplied from at least one of two or more of the content sterilization apparatuses.

16. The method for cleaning an aseptic filler according to claim 13 ,
wherein the aseptic water is stored and thereafter supplied.

17. The method for cleaning an aseptic filler according to claim 12 ,
wherein the interior of aseptic water supply piping, which supplies the aseptic water from the content sterilization apparatus to at least the filling portion chamber, is sterilized with a sterilizer.

18. The method for cleaning an aseptic filler according to claim 17 ,
wherein the aseptic water is supplied from at least one of two or more of the content sterilization apparatuses.

19. The method for cleaning an aseptic filler according to claim 12 ,
wherein the aseptic water is supplied from at least one of two or more of the content sterilization apparatuses.

20. The method for cleaning an aseptic filler according to claim 12 ,
wherein the aseptic water is stored and thereafter supplied.
