Whether it is an industrial dry ice machine or a small dry ice maker, the core principle of dry ice making machine is that high-pressure carbon dioxide is cooled by rapid decompression to make part of the liquid carbon dioxide form solid dry ice. The following are the detailed steps and principles:
- Rapid decompression
When high-pressure CO2 is released through an expansion valve or a special nozzle, the pressure drops sharply to normal atmospheric pressure.
- Phase change endothermic
The pressure reduction causes part of the liquid CO2 to vaporize quickly into gas, and this process absorbs a lot of heat.
- Solid dry iceformation
The remaining liquid CO2 was absorbed a lot of heat that the temperature drops sharply to -78.5℃, and form snowflake solid dry ice directly.
- Dry ice forming
The loose snowflake solid dry ice is pressed through a mold to form high-density dry ice block or granular dry ice, which is easy to store and use.
Through the above process, the dry ice making machine can efficiently convert liquid CO2 into solid dry ice. Dry ice machine complete solutions and more information 008618882125191.
