ABSTRACT:
A nitrogen injector system is provided including a nitrogen injector unit. The nitrogen injector unit includes liquid nitrogen with a head space having gaseous nitrogen at a pressure exceeding atmospheric pressure. An injector orifice is provided, as is a distributing disk which normally closes that orifice. The distributing disk is provided with metering apertures for receiving metered amounts of liquid nitrogen from a nitrogen receptacle and transporting those metered amounts to a position adjacent the injector orifice and for opening the orifice when the metered amount is in the requisite position. The pressure of nitrogen gas within the head space is utilized to eject the metered amount from the metering aperture into a container located at the dispensing position. Containers are advanced to the dispensing position on a container conveyor.
The distributing disk is rotated at a speed proportional to the speed of the container conveyor with a common drive such that a requisite amount of nitrogen will be dispensed to each container regardless of fluctuations in the speed of the conveyor.
A solenoid is provided for selectively disabling the ejection of liquid nitrogen by the disconnection of a gas discharge conduit which couples the injector orifice with the high pressure nitrogen gas within the head space.
