Dry ice: its innovative applications in dry ice blasting, restoration, pharmacy, and events

There are times when traditional cooling systems simply don't measure up. Dry ice is here to solve that problem, offering professionals and individuals alike a safe and sustainable solution. Also known as " Dry Ice ", this solid substance keeps both food and pharmaceutical products at optimal temperatures throughout the day, whether for a special event or simply a casual get-together with friends. But dry ice is also used for dry ice blasting operations. In this article, we will examine how dry ice can be used across different sectors, offering customers significant advantages beyond cleaning alone and product preservation.

Properties and Uses of Dry Ice

La dry ice, également connue sous le nom de glace sèche, est un solide constitué de carbon dioxide (CO2). It is called "dry ice" because of its sublimation property—that is, it transitions directly from a solid state to a gaseous state without passing through a liquid state, at atmospheric temperature and pressure.

The production of dry ice typically involves the compression and cooling of gaseous carbon dioxide. The gaseous CO2 is first compressed to a pressure of approximately 50 to 75 atmospheres (50,6 to 76 bar). This compressed CO2 is then cooled below its sublimation point (-78,5 degrees Celsius) by passing it through a heat exchanger. Under this pressure and temperature, CO2 transforms into dry ice.

To obtain blocks or pellets of dry ice, the solid CO2 is then extruded or compressed into various shapes and sizes according to the user's specific needs. The equipment used is the pelletizer.

The extrusion process allows the creation of blocks or pellets with precise and uniform dimensions, which facilitates their use and transportation. Once formed, dry ice must be stored in insulated containers (polystyrene boxes, special containers) to minimize sublimation and preserve its shelf life.

Dry ice is used for various applications, such as cooling, or food preservation, cryogenic cleaning and special effects in the entertainment industry.

Dry ice differs from other forms of ice because it contains no water and transitions directly from solid state to gaseous state without passing through a liquid state, a phenomenon called sublimation.

Benefits for Food Service, Catering, and Beyond

Thanks to its ability to sublime into cold gas, it is an excellent way to keep food products at below-freezing temperatures. Its use is particularly appreciated by catering companies and food service providers. Indeed, it not only extends the shelf life of fresh products, but also improves their taste quality.

Moreover, dry ice plays a crucial role in preserving heat-sensitive medications and reducing the risk of bacterial contamination when cleaning medical instruments. By maintaining medications at appropriate temperatures, it ensures their effectiveness and preserves their quality. Furthermore, its use for cryogenic cleaning cleaning medical instruments allows the elimination of bacteria and other contaminants without the use of water or chemicals.

Use at Events and Parties

Dry ice transforms parties into enchanting et mysterious experiences by producing a cold mist that envelops the floor like a soft blanket of snow. This dreamy smoke emanating from the dry ice adds a touch of mystery and elegance to events, captivating guests and transporting them into a magical world where the senses are awakened and emotions intensify.

Furthermore, dry ice offers an additional touch of sophistication to parties by allowing the rapid and efficient cooling of alcoholic beverages and cocktails.

Unlike traditional ice, dry ice does not dilute the flavors of drinks, thus preserving the intensity and complexity of each aromatic note. Guests are thus seduced by chilled cocktails with preserved flavors, offering them an exquisite and unforgettable taste experience.

Delivery and Storage of Dry Ice

Transport and Storage Conditions

To preserve the properties physical et products of dry ice, it is crucial to store it at a temperature below its sublimation point, which is -78.5°C. At higher temperatures, solid carbon dioxide will sublime rapidly and transform into gas, which will compromise the effectiveness of dry ice for required applications.

It is also essential to store la dry ice it in a dry place, away from direct sources of heat such as radiators, ovens or electrical appliances that may generate heat. Prolonged exposure to heat will accelerate la sublimation and reduce the shelf life of dry ice. To minimize dry ice loss through sublimation, it is recommended to store it in insulated containers, such as polystyrene foam containers or coolers specially designed for dry ice storage. Moreover, it is important to ensure adequate ventilation during storage, as the sublimation of dry ice leads to an increase in CO2 pressure in the air, which can pose safety and health issues if CO2 concentration becomes too high.
