Our dry ice machine is designed for efficient conversion of liquid CO₂ into high-density dry ice products. The equipment is available in two configurations: a 50-type dry ice pelletizer for producing dry ice pellets and a 120-type dry ice block machine for manufacturing customized dry ice blocks.
The machine can produce dry ice in various forms to meet the requirements of cold chain transportation, food preservation, industrial cleaning, pharmaceutical logistics, and laboratory applications. The dry ice pellet machine supports common pellet diameters of 3 mm, 16 mm, 19 mm, and 21 mm, while the dry ice block machine can be customized according to customer requirements.
What Is a Dry Ice Machine?
A dry ice machine is a hydraulic or mechanical press that expands liquid CO₂ into snow and then compresses it into high-density pellets or blocks. With a conversion ratio of ≥42%, our machines ensure minimal waste and maximum output.
Depending on application requirements, the machine can produce:
- Dry ice pellets
- Dry ice blocks
- Customized dry ice shapes
The resulting dry ice has a temperature of approximately -78.5°C, making it ideal for refrigeration and cleaning applications.

Compared with pellets, dry ice blocks have:
- Longer sublimation time
- Better cooling retention
- Easier storage and transportation
- Reduced dry ice loss
- Customizable Block Sizes
The machine supports customized mold dimensions for different industries and transportation requirements.
Common applications include:
- Vaccine transportation
- Pharmaceutical cold storage
- Long-distance food logistics
- Laboratory refrigeration
- Industrial temperature control
Working Principle of the Dry Ice Machine
The dry ice making process includes:
Step 1: Liquid CO₂ Supply
Liquid carbon dioxide is introduced into the machine under pressure.
Step 2: Dry Ice Snow Formation
Pressure reduction causes part of the liquid CO₂ to rapidly expand and cool, forming dry ice snow.
Step 3: Compression Molding
Hydraulic or mechanical pressure compresses the dry ice snow into pellets or blocks.
Step 4: Finished Product Discharge
The finished dry ice pellets or blocks are automatically discharged for packaging or storage.
