Apparatus for inerting the headspace of a container

摘要

Methods and apparatus for supplying an inert compound into the head space of a container. The apparatus has a delivery path which is made up of an inlet which receives a mixture of gaseous phase and solid phase inert compound, an outlet and a tortuous section. The tortuous section is located between the inlet and the outlet, and is situated so as to reduce the velocity of the solid phase inert compound as it passes through. The inert compound can then be delivered into the head space of a container at a lower velocity which increases the efficiency of the inert gas in displacing any air present.
