- About dry ice
Carbon dioxide (CO2) exists in three states: solid, liquid, and gaseous. Solid carbon dioxide is what we call 'dry ice'. When liquid carbon dioxide flows from a high-pressure low-temperature storage tank (with a pressure of 2.3 MPa) to the ice making chamber of a dry ice production machine (at atmospheric pressure of 0.1 MPa), a change in state occurs: 1 kg of liquid carbon dioxide will become approximately 0.4 kg of solid dry ice and 0.6 kg of gaseous carbon dioxide.
The temperature of dry ice (solid carbon dioxide) is -78.5 ℃, which is significantly different from the ambient temperature. Therefore, dry ice will sublime from solid to gas without leaving any residue. Due to its low temperature and sublimation properties, dry ice has been widely used in industry and daily life.
