The dry ice pelletizer is a specialized machine designed to convert liquid carbon dioxide into dry ice pellets through rapid expansion and extrusion. It is widely used in dry ice blasting, industrial cooling, cold chain transportation, and dry ice processing applications.
The machine can continuously produce high-density dry ice pellets with uniform size. The pellets can be used directly in dry ice blasting machines without any secondary processing.
According to different production requirements, the dry ice pelletizer is available in multiple models ranging from SL-50 to SL-500, covering capacities from small-scale use to industrial continuous production.
Working Principle of The Dry ice pellet maker
The dry ice pelletizer uses liquid CO₂ as raw material. Inside a sealed system, the liquid CO₂ is rapidly expanded, cooled, and compressed, converting it into solid dry ice.
The dry ice is then extruded through a forming die to produce pellets and discharged directly through the outlet.
The machine can be equipped with single-outlet or dual-outlet discharge pipes, depending on site requirements.
Dry ice containers can be placed directly under the discharge outlet, allowing the pellets to fall directly into the container, reducing intermediate handling, minimizing loss, and improving operating efficiency.
