Dry Ice

Just as an ice cube is the solid form of water, dry ice is the solid form of carbon dioxide (CO2).
Also known as carboglace or dry ice, dry ice is produced by expanding CO₂ stored at -20 (-4°F) and 20bars (290 psi) to atmospheric pressure. The gas thus passes from the liquid state to the solid state; it is then compressed using a machine called a pelletizer.

The pieces of dry ice are produced at a temperature of -78 (-108°F) in different diameters of 3mm (0.12 in) or 16mm (0.63 in) depending on the intended use.

Dry ice is 5 to 10 times more effective than water ice; it releases cooling power on the order of 150 frigories/kg.
CO₂ is captured at industrial sites, allowing its reuse and thus preventing its release into the atmosphere.

Performances

In performances, when in contact with warm or hot water, dry ice sublimates and produces a white fog. This solution is used to create stage effects.

Harvest

For harvest, winemaking, temperature maintenance, and inerting. During harvest, dry ice is used as an antioxidant. It prevents freshly picked grapes from oxidizing during transport and storage before pressing. This process, also called inerting, is especially important when temperatures are high as it amplifies oxidation. Dry ice also allows precise temperature control of the must. When mixed with the must during winemaking, it facilitates cold maceration, resulting in a fruitier, more balanced wine with more pronounced aromas than that produced by traditional methods.

Food Industry

In the food and agro-food sector (restaurants, caterers, and industries) for preservation, transport, maintaining the cold chain, or ultra-fast cooling (injected during a mixing phase).

Rodent Control

Rodent control: dry ice in stick form is used to combat rodent proliferation while remaining safe for other wildlife. Placed at the burrow entrance, it sublimates and fills the tunnel, suffocating the rodent.

Technical data of the grape harvest:
Cooling of harvest: 1.3 Kg (2.9 lbs) of dry ice lowers the temperature of 100kg (220 lbs) of harvest by 1°C (33.8°F)
Inerting: 2 kg (4.4 lbs) of dry ice generate 1 m³ (35.3 ft³) of carbon dioxide gas
Fermentation temperature control: 6 kg (13.2 lbs) of dry ice cool 100 litres (26.4 US gal) of must by 1°C (33.8°F)

Usage Precautions

To reduce these losses, it is recommended to store dry ice appropriately, namely:
• Away from moisture
• In a well-ventilated area to limit CO₂ concentration in the ambient air.
• Using closed polystyrene containers but never hermetically, as during sublimation the gas volume increases significantly (up to nearly 800 times), exerting high pressure on the container that can lead to an explosion.
Cryosystemoffers rental or sale of high-capacity insulated containers specifically designed for the safe storage of your dry ice.

Using dry ice carries risks:
• Risk of asphyxiation: Ensure that dry ice is stored and used in a well-ventilated space.
• Risk of burns: Dry ice is at a temperature of -80°C (-112°F), so thick gloves must be worn when handling it.
