The fully automatic dry ice pelletizer uses a process that directly pelletizes liquid CO₂. Combining a high-pressure hydraulic system with patented molding dies, it can rapidly produce high-density dry ice pellets. It supports one-touch automatic operation and features high efficiency, low waste, and stable operation.
The full range of models offers production capacities from 50 to 500 kg/h and supports the production of dry ice pellets in multiple sizes ranging from Φ3 to 19 mm. The dry ice density can reach 1550 kg/m³, with a stable CO₂ conversion rate of ≥42%. The equipment is widely used in industrial dry ice cleaning, cold chain transportation, the food and pharmaceutical industries, and scientific research and experimentation.
Main Applications of Dry Ice Pellet Machines
The granular dry ice machine can produce dry ice pellets in various sizes ranging from 3 to 19 mm, catering to diverse needs across all industries. Its core applications cover five major scenarios:
- Industrial dry ice blasting: used as a feedstock for dry ice blasting machines to remove stubborn stains from precision instruments, food-processing equipment, automotive engines, and industrial molds. It leaves no residue and causes no secondary pollution.
- Cold chain transportation and preservation: used as a refrigerant in the cold chain for fresh food, pharmaceutical reagents, and low-temperature ingredients. It extends shelf life and is suitable for long-distance transportation and warehouse preservation.
- Stage and film special effects: used to create smoke effects for stage performances, wedding events, and film and television productions. The smoke is uniform, and the effects are consistent.
- Laboratories and research: used for low-temperature freezing, sample preservation, and low-temperature experimental procedures in laboratories. Meets the low-temperature environmental requirements for scientific research and testing.
- Dry ice production and distribution: provides large-scale dry ice production capacity for dry ice distributors and gas companies. Supplies dry ice products of various specifications to local markets.
Core Value Advantages of the Dry Ice Pelletizer
Patented Molding Technology
The dry ice pelletizer utilizes a proprietary, self-developed ice-extrusion mold and an optimized hydraulic molding process. This results in a denser dry ice pellet structure with a density of up to 1550 kg/m³.
Compared to conventional pelletizing methods, it achieves:
- Stable CO₂ conversion rate of ≥42%
- No significant spray loss upon startup
- Uniform discharge and intact pellets
- Slower sublimation rate, resulting in longer transportation and storage times
High-density dry ice not only enhances industrial cleaning performance but also reduces losses during transportation, saving enterprises more on raw material costs.
Fully Automatic Control for Improved Production Efficiency
The entire dry ice pelletizer is equipped with a PLC control system and a touchscreen LCD. Operating parameters can be freely set according to production needs to enable automatic pelletizing and operation.
- One-button start
- Simple operation
- Adjustable parameters
- Continuous and stable production
- Reduced labor costs
Even operators without extensive experience can quickly begin using the machine after a brief training session.
Integrated Structural Design for a Smaller Footprint
The hydraulic station, power system, and pelletizing mechanism are all built-in. Compared to traditional split-type equipment:
- Saves installation space
- More compact layout
- Easier installation and maintenance
- Cleaner production environment
Additionally, the fully enclosed structure effectively reduces the ingress of external dust, improving the purity of the dry ice product.
High-Quality Components for More Stable Operation
The dry ice pelletizer main body is made of 304 stainless steel, which is corrosion-resistant, easy to clean, and suitable for long-term continuous production.
High-quality core components ensure the equipment features:
- Low failure rate
- Long service life
- Stable operation
- Low maintenance costs
For the food and pharmaceutical industries, food-grade hydraulic systems can be customized to meet higher hygiene standards.
Multi-Layered Safety Protection Design
To ensure production safety, the equipment is equipped with multiple protective measures, including:
- Safety alarm system
- Door-lock safety structure
- Adjustable support feet
- Fully enclosed housing
- Low-noise operation
These features not only facilitate daily maintenance but also effectively reduce operational risks.

How to Choose the Right Model for You?
When selecting the right dry ice pelletizer, we recommend focusing on the following aspects:
Select Production Capacity Based on Daily Output
- SL-50, SL-100: suitable for laboratories, small-scale distributors, and startup projects.
- SL-150, SL-200: suitable for small- to medium-sized dry ice production facilities and cold chain distribution centers.
- SL-300, SL-500: suitable for large-scale industrial cleaning service providers, gas companies, and large-scale dry ice production facilities.
Select Based on Pellet Size
The SL-50 supports pellets ranging from Φ3 to 16 mm, while the other models support pellets ranging from Φ3 to 19 mm, meeting the needs of different customers.
Select Based on Facility Conditions
Confirm the installation space, power supply configuration, and production layout in advance to select the equipment model best suited to your on-site conditions.
Customizable Configurations for Specialized Industries
For industries such as food, pharmaceuticals, and bioproducts, food-grade hydraulic systems and electrical configurations compliant with local standards are available.
How long do dry ice pellets last?
Dry ice pellets do not melt into a liquid but sublimate directly into carbon dioxide gas. Under good insulation conditions, they generally last 24–36 hours. The exact duration depends on factors such as ambient temperature, packaging method, and dry ice density.
To maximize the shelf life of dry ice, we recommend the following measures:
- Store dry ice in a specialized insulated container or dry ice storage box.
- Store it in a cool, shaded environment as much as possible, and avoid direct sunlight.
- Minimize frequent opening of the packaging to reduce the exchange of hot and cold air.
- Maintain a dry environment and prevent dry ice from coming into contact with moisture, as this accelerates the sublimation process.
- Plan production schedules based on actual usage needs to ensure that dry ice is produced and used immediately, which can further reduce losses from transportation and storage.
