Liquid Nitrogen Dosing Application Focus - 1

Preservation Wine Bottling Chart is known industry wide for its frost-free, vacuum insulated, liquid nitrogen equipment and piping distribution systems. With over 3,000 dosing units installed, Chart has a wealth of application specific knowledge across a wide range of dosing applications. The Challenge As the wine industry transitions to screw caps, wine makers are presented with new, unique challenges. Although screw caps eliminate the concern of “cork-taint”, screw cap bottles have a greater volume of headspace. Wine is exposed to oxygen trapped in the bottle headspace which in turn can result in increased dissolved oxygen levels, even after the cap is applied. Chart can help make this transition a success. The Solution By introducing liquid nitrogen into the bottle after filling, wine makers reduce headspace 0., content by more than 85%. Typical results are 2.0 - 2.5% 0.,. Less headspace 0., results in a significant reduction of dissolved 0., pickup. A very small dose of liquid nitrogen is dosed into the filled bottle. One part of liquid nitrogen warms and turns into 700 parts of gas, displacing 09 from the headspace.

Liquid Nitrogen Dosing Application Focus - 2

Pre-Fill and Pre-Cap Purging with Liquid Nitrogen Inerting with Liquid Nitrogen Effectively flushes O2 out of the bottle head space Extends shelf-life in screw cap packages Keeps the fruit in every pour PC-HS mean PC-DO mean PF-HS mean PF-DO mean HS = Headspace DO = Dissolved O2 PC = Pre-cap (Headspace) PF = Pre-Fill (Empty Bottle) Conclusion: Lowest HS and DO with pre-cap (headspace) liquid nitrogen purge. FSO2 Results FS02 Test Results FS02 ppm Conclusion: Liquid nitrogen dosing best “locks-in” FSO2 levels. Liquid nitrogen dosing provides winemakers with better diagnostic insights for...
