To reduce an amount of use of a replacement gas used for replacing air in a container. A gas replacement system includes: a washing machine that washes the container with water; a filling machine that fills the container with a content fluid; a sealing machine that seals the container transferred from the filling machine; a chamber that covers the filling machine and the sealing machine, and contains a replacement gas; and a water discharge mechanism (washing machine) that discharges the water in the container having been carried into the chamber while containing the water out of the container in the chamber. The water in the container is replaced with an ambient gas in the chamber along with the discharge of the water.

Gas replacement system and gas replacement method

There is provided a filling-and-sealing device and a filling-and-sealing method capable of reducing an amount of use of a replacement gas used for replacing air in a container. The filling-and-sealing device includes a filling machine that fills a container with a content fluid; a sealing machine that seals the container transferred from the filling machine with a lid; a chamber that covers the filling machine and the sealing machine; a gassing system that replaces, in the chamber, a gas in the container with a carbon dioxide gas by introducing the carbon dioxide gas as a second replacement gas supplied from a tank; and a pre-gassing system that replaces the gas in the container with a first replacement gas that remains in the chamber containing the carbon dioxide gas before processing by the gassing system.
