One of main uses for dry ice in the food industry is for meat processing, specifically sausage making. Dry ice is ground up in the meat to prevent bacteria growth and keep the meat product cold while made and shipped. By the time it has reached its destination, the dry ice will have fully sublimated, leaving nothing behind.
Anything you need to keep frozen during shipping, meat, food, other perishables, can be shipped with dry ice. Check with your provider to know the limits for much dry ice you can ship, but it is usually around 5 to 10 pounds. Dry ice is a popular way to keep things frozen during shipping because it lasts well and there is no cleanup, once the dry ice sublimates, it's gone.
Science and Research
The main use for dry ice in research facilities is to rapidly freeze samples and products for long term storage. Being able to quickly freeze samples is important for the reproducibility of experiments, it also keeps samples much colder than regular ice.
Craft Brew and Beverage Carbonation
In the craft brew and beverage industry, carbonation is a critical aspect of the production process. CO2 serves two main purposes. First, in craft brewing, CO2 is used to purge oxygen from the headspace in beer tanks, minimizing dissolved oxygen levels and preventing flavor compound oxidation. This results in better-tasting and longer-lasting beer. Secondly, carbonation is the process of dissolving CO2 gas in drinks, giving beer its foamy, fizzy texture. This carbonation process is also responsible for the bubbles in soda waters and soft drinks.
Greenhouse Yield Enhancement
CO2 plays a role in agriculture. When used in greenhouses, it contributes to increased crop yields. There are different strategies for disbursing CO2 in greenhouses, but each way can significantly shorten the growing period while enhancing the overall yield and quality of crops.
Dry Ice Blasting
Dry Ice blasting is similar to pressure washing. The main difference is there is much less cleanup since you don’t need to worry about water, just the dirt that you lift off whatever you are cleaning. It works by blasting small pellets at supersonic speeds, causing the ice to sublimate on impact. That lifts the dirt and impurities from the source. Dry ice blasting is non-abrasive, non-conductive, non-toxic, and non-flammable, making it a safe option for cleaning many different surfaces.
