Purging Corney Kegs

[BM1]

I was thinking ...about different ideas on purging corney kegs and I got some interesting feedback on another forum http://hbd.org/cgi-bin/recipator/discussion?item=21830 that caused me to think a little deeper about what a time saver it would behttp://hbd.org/cgi-bin/recipator/discussion?item=21840 based on how other people do it.If a person already had the tools and wanted to be thorough about it,it might be worth the effort.What do ya think?

Probably not important,but I love a challenge.
Give me input please or

Maybe I'm missing the point, but I'm really not familiar with the keg oxidation issue. I've been kegging for around 5 years or so and I myself have not encountered it. When filling the kegs I try to fill with as little agitation as possible and I just make sure that there is CO2 on the beer at all times. If I plan aging the beer for awhile in the keg, I will apply CO2 to the IN port and open the pressure release for 5 seconds or so to purge the oxygen.

It sounds like the guy from the link owns his own co2 distributorship -wasting co2. If you want to follow this method, I would wait short bits to allow the gas mixture of o2 to co2 to come to equilibrium, then purge off the o2. co2 is heavier than co2. But the 2 will mix together in a solution for a short period. You want to allow them to seperate into their own layers, purge off the lighter o2, being left only with the nice co2 blanket.

My own method for filling kegs includes adding some co2 to the empty keg, rack the beer into the keg, hook up the co2 and crank the pressure up on the regulator to about 40 PSI. I can hear the seal on the lid really seat. I disconnect the co2 to listen for any leaks from out/in posts, lid, and pop off. If no hissing, I hook up the co2 again, and purge 3-4 times about a second each waiting a short bit in between each purge to allow any o2 to rise to the top of the keg. I haven't been kegging as long as Dewayne, but I don't believe I've had any issues.
I forgot to mention that every time I hook up the co2, or tap to the keg I give each male/female connector a good spray with Star San.

I do pretty much what John does. You can usually see a nice layer of co2 at the bottom of the keg before you fill it. Then fill from the bottom up pushes out most of the o2. Then put the lid on a purge a few more times at high pressure. No oxidation problems here. I even fill my swingtops from the tap. We cracked open a blonde from the contest last Nov that I filled on from the tap on the Upland bus and no oxidation.
