Cryogenic liquids are used in the food and beverage industry to cool, chill, freeze, and preserve in a wide variety of applications. Both liquid nitrogen and liquid carbon dioxide are often used in these applications. Liquid nitrogen is completely inert, colorless, tasteless, odorless, and has no adverse environmental effects. Cryogenic freezers and chillers are often chosen over mechanical freezers for the food industry due to the reduced equipment capital investment, faster and more efficient heat transfer, and reduced floor space claim.
Cryogenic liquids are also used to supply the gas used in what the industry calls Modified Atmosphere Packaging (MAP) and Controlled Atmosphere Packaging (CAP). Liquid nitrogen injectors, popular in the beverage industry but also used in other packaging applications, may be used to inject liquid nitrogen which rapidly expands displacing air in the container. This can be used to lengthen product life or to pressurize the container.
Technifab’s products have long been used in the food and beverage industry. Besides providing the best system performance and quality, some of our standard options are designed specifically with the food and beverage industry in mind. Stainless steel construction fits naturally in an environment where cleanliness is extremely important. We even offer a protective wrapping for our bendable pipe where convoluted tubing makes clean-up difficult.
Technifab’s Vacuum Jacketed Pipe (VJP) and transfer hoses are used to take liquid cryogens such as liquid nitrogen and liquid CO2 from the storage vessel or tank to the equipment (called the use point). Valves and Phase Separators may be used in the system to deliver a consistent and high quality liquid cryogen.
Liquid Nitrogen Injectors (such as Technifab’s Techinjector) can be used to inert beverages and food product containers with nitrogen gas at production line speeds. Injecting liquid nitrogen into a container can even be used to mildly pressurize bottled water or other PET containers allowing thinner containers to be used!
Technifab has been producing liquid nitrogen injectors for the packaging industry since the 1990’s, you can read about the history of liquid nitrogen injectors and their use and application here.
