A liquid-nitrogen injection system comprises a vacuum-insulated reservoir that is held aloft and to one side of a flexible dosing arm. Such reservoir is completely sealed and capped on its top and sides, the vent, feed, return, and supply conduits enter only from the bottom. The feed and return conduits connect to the dosing arm through a long flexible, stainless steel, vacuum-insulating jacket. Such allows an injection nozzle at the end of the dosing arm to be adjusted up and down, in and out, and even tilted relative to both the assembly line and the r...


[ What is claimed is:] [1.] A flexible extension arm, comprising:a vacuum-insulated feed conduit for circulating a flow of liquid nitrogen from a reservoir to a control valve in a dosing head; anda pair of vacuum-insulated return conduits for circulating said flow of liquid nitrogen back from said control valve in said dosing head;wherein, a system for injecting liquid nitrogen into food and beverage packages on a high speed production line just before environmental sealing is provided.
