Dry Ice Pelletizers

General information about CO2 and dry ice

Dry Ice is the product of processing liquid CO2 . If the pressure of liquid CO2 is suddenly released, a proportion of that liquid will change to the solid state (becoming dry ice “snow”) and the remainder will revert to gas (revert gas). When the snow is compressed under hydraulic or mechanical action, blocks or pellets of dry ice are formed. The revert gas (gaseous CO2 ) can be readily reclaimed and converted back to liquid by recompression and reliquefaction, thence returned to the dry ice block machine or pelletizer for further processing.

At atmospheric pressure it has a temperature of approx. -79 °C (-110°F). The solid CO2 goes directly into the gaseous state. This evaporation (sublimation) leaves no residues. Dry ice is non-toxic, non-flammable, inert, odourless and bacteriostatic. It is white and has a density of approx. 1'500 kg/m3 (93.6 lb/ft3) in its compact state. Dry ice is an ideal refrigerant, which is particularly suitable for various applications. It has a high cooling capacity and the heat transfer is very high when it is in direct contact with the cold material.

Carbon Dioxide has 3 physical states of gas, liquid and solid which depend on temperature and pressure.

CO2 is derived from a number of sources including combustion of carbonaceous fuels, fermentation, natural wells, and as a by-product of industrial processes such as ethylene oxide and bioethanol production and ammonia synthesis.

Below the triple point (5.18 bar, - 56.6°C) (7'512,96 psi, - 69,88 °F) CO2 can only appear in its solid and gaseous state. Dry ice is the common trade name for solid CO2 . At atmospheric pressure it has a temperature of approx. -79°C (-110,2 °F). The solid CO2 changes directly into its gaseous state. This evaporation (sublimation) does not leave any residues. Dry ice is non-toxic, non-inflammable, inert, without smell and bacteriostatic. It is white and has a density of approx. 1'500 kg/m3 (93,64 lb/ft3) in its compact state. Dry ice is an ideal refrigerant which qualifies especially well for various applications. It has a high cooling capacity and heat transfer is very high when in direct contact with the cold material.

Within a temperature range between -56.6°C (-69,88 °F) and 31°C (87,8 °F) and pressure greater than 5.2bar and less than 74bar (1'073,28 psi) respectively CO2 is in its liquid state except at very high pressures. This means that, below 5.2bar (754,20 psi), CO2 exists only in its solid or gaseous state. At 5.2bar (754,20 psi) and - 56.6°C (- 69,88 °F) all three states (solid, liquid and gas) are present. This is called the triple point.

The critical point of CO2 lies at a temperature of approx. 31 °C (87,8 °F) and a pressure of approx. 74 bar (1'073,28 psi). Normal CO2 liquid can only be formed at temperatures below 31 °C (87,8 °F). Above the critical point there is no physical difference between the liquid and gaseous phase. This supercritical state is also called „Fluid“. The liquid state is important for the storage and transportation of CO2 as well as during cooling and freezing applications. During release of the liquid CO2 to atmosphere a temperature of -79 °C (-110,2 °F) is reached. This is associated with a high cooling capacity due to the evaporation heat which is extracted from the environment when releasing the liquid CO2 .
CO2 gas has a density of approx. 1.9kg/m3 (0,12 lb/ft3) at atmospheric pressure and +15°C (+ 59 °F). CO2 has many unique and beneficial features which make it valuable in the preservation of packaged food, in explosion and fire protection, in pest control and as protective gas in inert-gas-welding. In all these applications it is important for the CO2 gas to drive out and replace the atmospheric oxygen. Moreover, CO2 gas is used for enriching the atmosphere in greenhouses, in storing fruits and vegetables and for pH control when treating potable and waste water.
Dry ice is an ideal cooling media which can be used for many applications. It has a high cooling capacity. Dry ice blocks/slices or dry ice pellets are used for cooling purposes.

ASCO Dry Ice Blasting is a powerful, gentle, dry and ecologically friendly cleaning method causing no secondary waste. It is applied in many industries. For the cleaning of surfaces with our ASCO dry ice blasting technology dry ice pellets with the diameter of 3 mm (0,12 in) are standardly used. Dry ice pellets with a diameter of 1.7 mm (0,06 in) can also be used for the cleaning of delicate surfaces. For cooling purposes dry ice blocks and pellets with a bigger diameter are used.
Dry ice is produced from liquid carbon dioxide (CO2). Inside a dry ice pelletizer, the liquid carbon dioxide is expanded under controlled conditions to form dry ice snow. This snow is then pressed through an extruder plate into round, hard pellets (elongated grains with a diameter of 3 mm or 1.7 mm according to the used extruder plate) for dry ice blasting purposes or into larger pellets/dry ice slices/blocks for cooling purposes.
