The working principle of stage dry ice machine

Do you know how to achieve the fairy-like smoke effect on the stage we often see? In fact, most of them are practical dry ice machines, so how does it work? Let me tell you below.

The principle of the stage dry ice machine is very simple. The internal heating is used to quickly sublimate the dry ice and guide it through the exhaust air. Because carbon dioxide is heavier than air and the temperature is very low, it will sink on the ground. The ice-cold carbon dioxide that is removed meets the surrounding air to condense the water vapor in the air and form small water droplets. The smoke is gone. This smoke effect is very environmentally friendly and is the most widely used stage smoke effect in the world.

The WUAI-3000 dry ice smoke machine uses the principle of -78 ℃ solid dry ice to generate a large amount of white smoke when heated and vaporized at normal temperature, providing a smoke effect for the stage. At present, small power dry ice machines under 3kW are used in China, which is suitable for a medium and small stage, but cannot be used for a large stage. High-power dry ice machines such as WUAI-6000 have a large smoke volume, emit smoke quickly, can quickly fill the stage, and have the advantages of environmental protection. They have been widely used in developed countries.
