Heatflex's Gambrinus increases shelf life of beer

Heatflex Corporation industrial heating systems has launched Gambrinus to reduce Total Package Oxygen (TPO) in beer-bottling lines. 

The initial Gambrinus unit has been installed and tested in a high-volume commercial brewery and bottling plant in the Southeast region of the US, and has been shown to reduce the TPO in a beer bottle from 70 parts per million (PPM) to 30 PPM, increasing the shelf life of the beer and improving its quality and flavor consistency. 

"The Gambrinus product provides the brewery industry with an all-natural alternative to adding chemicals or biologicals, and reduces TPO in a beer bottle by more than 50%​," said Steve Hausle, VP, sales and marketing, Heateflex. 

As a result of the bottling process in commercial breweries, residual oxygen remains in the top of the bottle after filling. This results in oxidation that reduces the shelf life of the product as well as its flavor and quality. 

Various approaches have been tried by the brewing industry to reduce TPO, including the addition of oxygen-scavenging enzymes or ascorbic acid to the bottle, and mechanical approaches such as hitting the bottle with a hammer to increase foaming and displace oxygen. 

Gambrinus is a stainless steel in-line heater that injects a small and precise amount of filtered water into each beer bottle to induce correct foam characteristics and displace oxygen.

The heater connects to a jetting tip when installed in a beer filling subsystem in the plant’s bottling line. 

The heating process keeps the jetting tip clean because the heat leaves it dry and sterile. 

Based on the TPO reduction results achieved in the initial bottling plant installation, additional installations are being planned by the Heateflex brewery customer in its other bottling lines.
