PURGING DEVICE, PURGING STOCKER, AND PURGING METHOD

摘要

[Problem] To provide a purging device that can appropriately perform purging while also conserving a purge gas. [Solution] A purging device (4) that is provided with: a first purging nozzle (41) that supplies a purge gas (G1) to a container (F) that is a purging target; an internal-state detection unit (8) that detects the internal state of the container before the first nozzle begins a purging process; and a purge determination unit (48) that, on the basis of detection results from the internal-state detection unit, determines purging conditions for the container.
