An elongated CO.sub.2 snow forming header is provided for disposition within an elongated insulated container and includes removably closable liquid CO.sub.2 inlet structure at each of its opposite ends. The header includes a central longitudinal supply pipe into either end of which liquid CO.sub.2 may be admitted and a pair of oppositely laterally spaced header lines supporting snow forming nozzles at points spaced longitudinally therealong for discharging jets of CO.sub.2 snow onto opposite sides of the center supply line. Lateral communicating lines communicate each end of the supply line with corresponding ends of the header lines and the communicating lines open into the supply line in a manner such that rapid inflow of liquid CO.sub.2 past the communicating lines causes an appreciable portion of the liquid CO.sub.2 passing through the header lines to be recirculated through the center supply line.
A CO.sub.2 snow forming system including a supply line having first and second ends, said first end including inlet means for admitting liquid CO.sub.2 therein and said second end being closed, a header line generally paralleling said supply line and including outlet and inlet ends corresponding to said first and second ends, respectively, a first pair of communicating pipes, one of said communicating pipes opening into and communicating said second end with said inlet end, the other of said communicating pipes opening into and communicating said outlet end with said first end, said header line including a plurality of CO.sub.2 snow forming nozzles supported therefrom at points spaced longitudinally therealong and opening outwardly of said header line toward said supply line and operative to discharge jets of CO.sub.2 snow onto said supply line, said other communicating pipe opening into said supply line in a manner defining eductor means operative to draw liquid CO.sub.2 into said first end of said supply line from said other communicating pipe responsive to rapid flow of liquid CO.sub.2 within said supply line from said first end toward said second end.
A CO.sub.2 snow forming system including a central supply line including first and second ends, a pair of header lines generally paralleling and spaced on opposite sides of said supply line, each of said header lines including a plurality of CO.sub.2 snow forming nozzles spaced longitudinally therealong and supported and opening outwardly from said header line toward said supply line, first communicating means communicating said first end of said supply line with the corresponding ends of said header lines and second communicating means communicating said second end of said supply line with the corresponding ends of said header lines, each end of said supply line being removably closed and including liquid CO.sub.2 inlet means, said first and second communicating means opening into said supply line in a manner defining eductor means operative to draw liquid CO.sub.2 into said supply line from the corresponding communicating means responsive to rapid flow of liquid CO.sub.2 through said supply line from past said corresponding communicating means toward the other of said first and second communicating means.
