Pressurization in Packaging Applications A precise dose of liquid nitrogen is delivered immediately before capping or seaming. The trapped LN2 quickly vaporizes, pressurizing the container. In hot fill applications, the nitrogen pressure counteracts the vacuum created when a hot product cools. Typical applications for this method include bottled water, energy shots, flax seed oil, juices (hot and ambient fill) and vinegar. Preservation Applications An exact dose of liquid nitrogen is introduced seconds before the seamer or capper. The small dose of liquid nitrogen gasifies, 700 times its volume, in the process. The large volume of gaseous nitrogen pushes the oxygen out of the container. Applications for preservation include automobile oil, condiments and .

The tunnel freezer uses liquid nitrogen (LIN) as a refrigerant to freeze food directly, suitable for all kinds of foods. It is modular in design, enabling you to expand production by adding additional tunnels for a longer freezing production line. It is available in several models and belt widths with production rates of 300–2, 000 kg/h .
