HOW IS DRY ICE MADE?

Dry ice is made by pressurising and cooling high-purity carbon dioxide gas into a liquid form. The liquid CO₂ is injected into a hydraulic press chamber where the atmospheric pressure converts it to a snow-like consistency. The CO₂ snow is then compressed into solid blocks or pellets.

Any CO₂ liquid that does not transform into snow is recovered in a CO₂ gas form and recycled into the production process. The density of the compressed CO₂ snow depends on the applied pressure and the pressure time. The density of a compressed block can reach 1.56g/cm3 as a maximum at a temperature of -78.64°C. Once compressed into a solid state, Dry Ice will slowly revert to its original gas form. This gives the appearance of a fog emanating from it.

There are different types of dry ice products. It comes in three forms: pellets, blocks, and slices. Each form is designed for specific needs.

FOOD GRADE DRICE®

1.7mm and 3mm Pellets

High density (1.6g/cm3), cylindrical 3mm diameter dry ice pellets developed exclusively for dry ice blasting and food processing.

Drice is multi-purpose and is primarily used in clean blasting and industrial food processing. For the latter, rice-sized grains of dry ice are directly mixed in with the product to keep temperature low and reduce spoilage, and in the case of bakeries – retard yeast growth in the dough.
