Interesting new carbing kit

No one likes waiting, and the QuickCarb is the way to eliminate the wait from carbonating your homebrew.  This high-pressure co2-injection system from Blichmann Engineering™ will carbonate a keg in 30 minutes, with no chance of over carbonating your beer.  All connectors are included, and the unit hangs from the front of your keg.

Use is simple,  just sanitize the unit using the built in pump, and connect hoses to your Keg and CO2 system.  Turn on the gas, plug in the unit, and 30-40 minutes later, your beer will be perfectly carbonated.  Cleanup is just as easy, as you can run cleaner and sanitizer through the system using the pump as well.

Bloody expensive though, rocking back and forth or my patent pending process much cheaper

I need a machine to do the rocking for me. Maybe a rocking horse, and a toddler.

It looks as though the pump pulls the beer through the liquid post, via an air stone back through the gas post. what about the residual oxygen in the top of the cornie ? Normally you would burp this out in the traditional techniques. YOU could end up with oxidised carbonated beer?

Clever. Once the headspace is burped you've no more risk of oxidation. CO2 is injected into the flow of beer.

[Sorcerers Apprentice]

The beer is oxidised by the movement from one vessel to another, to minimise this it's better to fill the corny keg with CO2 before filling into it and prevent splashing. Its better also to discard the first runnings, as the beer air interface within the hose will also add to the dissolved oxygen content of the beer. As BB mentioned in another thread all of the auto syphons which he had checked drew in air as he could see a stream of bubbles drawn in around the seal on the inner pipe. So even with pre charging the keg with CO2 you could end up with dissolved oxygen in your beer. The best way to remove oxygen from beer is either by bottle conditioning or gas stripping, you drive it off by passing CO2 through the beer vertically rather than horizontally as per the design in this unit. If you reverse the connections on the corny  keg and drive CO2 through the liquid post, it will drive off the dissolved oxygen. It's considered bad practice in professional brewing as it also drives off some of the flavour compounds at the same time.
