Top snowing

Air Liquide’s top snowing systems utilize carbon dioxide (CO2) for on-demand process cooling of baked products, meats, seafood and processed foods. This simple chilling solution enables temperature control and offers a protective atmosphere while food products are being mixed or blended. Carbon dioxide snow horns mounted on the covers of blenders or tumblers expand liquid carbon dioxide into dry ice snow on the top of food products. The snow mixes easily with food products, providing spot cooling on demand. As dry ice sublimes to a vapor, there is no ingredient change to the food product. Carbon dioxide can be antimicrobial and anti-fungal, providing a protective atmosphere that can hinder additional bacterial growth in some food products.



Air Liquide offers a carbon dioxide snow horn for top snowing applications.
