Abstract
PURPOSE: To provide titled apparatus having a simple structure and allowing uniform shape formation of dry ice by a method wherein dry ice is compressed and formed in a forming cylinder. A lid which is opened or closed by a spring attached to the end of the forming cylinder is connected to a pressing device and moves it.
CONSTITUTION: When solenoid valve 14 is open, liquefied carbon dioxide is blown from container 15 into a compression-forming chamber 18, adiabatically expanded to form snow flake carbon dioxide. Then, hydraulic cylinder 2 is actuated to push down a push-tool 10, so that snow flake carbon dioxide is pressed into square dry ice 4. Then a timer is actuated to stop the hydraulic cylinder 2, the push-tool 10 is slightly lifted up to remove the internal pressure in the forming chamber 18, then open-lid spring 28 pulls a lid 6 to open it. Then the hydraulic cylinder 2 extends to cause the push-tool 10 push out dry ice 4 to a product feed plate 8. Then the hydraulic cylinder 2 returns to the original position, and the open-lid spring 31 is actuated to close the lid 6.
