CO2 Dry Ice Production
Dry ice is the solid form of CO2 with a temperature of -79° C. At atmospheric pressure dry ice sublimes directly from a solid back to gas. It is called “dry ice” as it does not contain water and does turn to a liquid.
For cleaning purposes, dry ice in the form of 3 mm diameter pellets are most commonly used. For cooling and catering purposes, we recommend 10 mm or 16 mm diameter sticks.
Dry Ice made for
Dry ice pellets are made from liquid CO2 stored in a pressurized tank. When expanding the liquid CO2 it forms snow. This snow is compressed and extruded through an extruder plate giving the final dimensions of the pellets. The equipment producing the pellets is called pelletizer.
Dry ice pellets are stored and transported in well-isolated containers. Good quality containers will limit the evaporation of the pellets to a few percent per day.
PME provides its Dry Ice-based services in Saudi Arabia and Bahrain which serves the following sectors:
Dry Ice In The Industrial Sector
Dry Ice blasting -also called cryogenic or CO2 blasting- has remarkably proven a significant benefit associated with its cleaning capability and its applicability to a broad range of industries. Dry Ice blasting is used to clean machinery, electrical installations, electro-mechanical equipment and surfaces during live running operations. Dry Ice blasting has resulted in considerable increases in productivity, service quality, as well as substantial bottom-line savings.
Rust, dirt, dust, coal dust, varnish, mold, petroleum, oil, grease, paint, moss, plaster, marine growth, carbon build-up, mold, mortar, cement, Teflon adhesives, glue, wax resin, silicones, soot, weld splash and protective film.
Surfaces Cleaned with Dry Ice:
Metal, ceramics, stone, marble, plastic, glass, fiberglass, pipes, ovens, fans, turbines, mixers, tanks, cylinders, composites, machinery, high polished molds, presses, brick, conveyor belts, vessels, charred surfaces, electronic, gears and more.
Storage and Shipping
Dry Ice is used by hospitals, clinics and laboratories for the storage and shipment of temperature-sensitive items such as biomedical samples, organs, blood, medicine and vaccines.
The Dry Ice extremely cold temperature and the zero remnants makes it the best option for storing and transporting sensitive medical materials that must remain cold for an extended period.
Cleaning and Disinfection: Dry Ice can also be used to clean and disinfect medical and industrial equipment as it is not a pollutant and does not have a detrimental effect on the equipment itself during live running operations.
Spraying Dry Ice on the surface instantly decontaminate the treated area. This method is economical, environmentally safe, reduces waste and the usage of aggressive chemicals.
DRY ICE IN THE FOOD AND BEVERAGE INDUSTRY
Dry Ice is used as a non-cyclic refrigeration technique to preserve ingredients and food as a replacement of the mechanical cooling methods. It is frequently used for the below purposes:
- Food processing and distribution
- Food preservation process
- Food presentation – fog effect
- Serving special and fine dining dishes
- Making of ice cream and cold desserts
