Abstract

Injection means for injecting a liquified gas such as sulphur dioxide into a container such as a wine storage tank and avoiding 'icing up' the valve mechanism, wherein a three limbed 'T' piece of conduit receives the liquified gas, each having a separately controlled valve, one of the limbs being connected to a source of gas which is not liquified, such as nitrogen, the nitrogen blowing the liquified sulphur dioxide gas out of the three limbed 'T' piece when two of the valves are opened. The volume of the 'T' piece accurately determined the dosage of sulphur dioxide.
