Dry ice compressor device

An apparatus for compressing dry ice, the apparatus comprising:

• a hollow cylinder;
• thermal insulation disposed in thermal communication with the cylinder;
• a post disposed coaxially in the cylinder;
• a piston defining an opening therein and being slidably disposed in the cylinder, the opening slidably receiving the post therein;
• a biasing device operatively coupled to the piston;
• an inlet port defined in a sidewall of the cylinder and connectable to a source of liquid carbon dioxide, the inlet port being configured to introduce liquid carbon dioxide into the cylinder, the inlet port being further configured to expand liquid carbon dioxide to dry ice and to gaseous carbon dioxide;
• and
• an openably closable lid positionable among a first closed position configured to vent gaseous carbon dioxide from the cylinder, a second closed position configured to leakably close the cylinder to permit carbon dioxide flakes to be compressed in the cylinder, and an open position.
