Working Principle and Selection Parameters of Dry Ice Maker Machine

Dry ice maker machines are specialized equipment that produce solid dry ice from liquid carbon dioxide. They are primarily divided into two categories: industrial cleaning machines and catering smoke machines, with prices ranging from thousands to hundreds of thousands of yuan, catering to different production scales.

1. Core Working Principle

Flash Snowmaking: High-pressure stored liquid carbon dioxide is instantly depressurized through an expansion valve, directly converting into snowflake-shaped solid carbon dioxide.

Extrusion Molding: The snowflake-shaped dry ice is fed into a hydraulic device and compressed into uniformly dense granules or blocks.

Completely Waterless Process: Dry ice sublimates directly into gas, leaving no liquid residue, making it suitable for cleaning delicate equipment that is sensitive to water or electricity.

2. Core Selection Parameters

Capacity: Small machines 50-150 kg/h, medium machines 300-500 kg/h, large fully automatic models can reach 500-1800 kg/h.

Conversion Rate: High-quality models achieve a CO conversion rate of approximately 45%, while lower-end models only reach 35%-40%, directly impacting the production cost per ton of dry ice.

Dry Ice Density: Qualified products have a density of 1.4-1.55 g/cm3. Higher density results in slower evaporation and lower storage and transportation losses.

Particle Size: Standard sizes include 3mm (precision cleaning), 9mm/16mm (industrial cleaning), and 25mm blocks (cold chain transportation).
