Proper use

The machine produces dry ice pellets con-
sisting of liquid carbon dioxide. The size of
the dry ice pellets is selected via different
extruder plates.
The machine is only to be used in dry
rooms.

Function

Liquid carbon dioxide streams into the cyl-
inder and hardens into dry ice snow by the
drop in pressure. This dry ice snow is com-
pacted by a hydraulic cylinder and pressed
through the extruder plate. This creates cy-
lindrical dry ice sticks, which breaks down
into pellets.
