APPARATUS FOR PRODUCING DRY ICE AND PRESSURE RELIEF THEREOF

摘要

A device for producing a solidified block of carbon dioxide includes first a nd second housing portions removably connectable together. The first and second housing portions form an interior molding chamber that is adapted to receive liquid carbon dioxide at a pressure where expansion of the liquid carbon dioxide occurs, resulting in a mixture of solidified and gaseous carbon dioxide. A pressure relief device includes a biasing member for biasing the first and second housing portions together. T he biasing member permits relative movement between the first and second housing portio ns when internal pressure from the gaseous carbon dioxide exceeds a predetermined amount. With this arrangement, relative movement between first and second housing portions causes gaseous carbon dioxide to be released from the interior molding chamb er to thereby reduce the internal pressure.
