Default Can I use a Corny Keg as a Primary Fermenter?

My fermentation chamber can only hold one 5 gallon ale pale, which sucks. However, I have a bunch of corny kegs and I could fit around 3 of them inside it instead. If I purged it everyday, couldn't this work?

Thanks,

Matt

You can put an air lock in one of the posts. FYI they are not fun to clean when your done.

Do like this and you will be all set to corny keg as a fermented vessel. No issue with cleaning.

Fill keg with hot water and scoop of PBW or Oxiclean, let it sit for several hours, rinse with lots of water. Really not difficult to clean at all. Simpler than a slippery glass carboy IMO.

I've been experimenting with fermenting in corny kegs and so far I like it. I transfer the wort to the keg after boiling without cooling it, seal it, let it cool down overnight, then pitch the yeast the next day. I use some rubber tubing attached to the gas-out post for a blow off. Once fermentation is complete I transfer to another keg using C02 to avoid exposing it to air/oxidation. This can be accomplished by using a jumper to connect the liquid out posts on both kegs.

No issues so far.

During the past year, I fermented around 7 beers in corny kegs and am planning to go back to buckets for 2012 for at least some of my brews.

Downsides:
1. The kegs are a total PITA to clean
2. Trub clogged my dip tubes & disconnects whenever I tried to push beer from fermentors to kegs. Ended up syphoning every time.
(cutting or bending the dip tubs might have helped ... )

Upsides:
1. Easy to move keg in and out of fridge for wort chilling & crash cooling.
2. Like the idea of fermenting in stainless

Good luck!

Guessing the tubing isn't too big, maybe 1/4" id? If so is there risk of krausen clogging it?

So it looks like a spare lid drilled and tapped for a fitting for a blow off tube and a small pail of water for an airlock and transfer with an autosiphon when done... I like the sound of that because I too have room for one pail or three/four kegs. I'm not too sure about the direct transfer because of trub without going through a filter of some kind, but an autosiphon doen't create much airation and it will be under pressure soon anyway, May have to give this a try. And BTW a pressure washer and PBW will clean a Corny in no time at all. Then a douche of Star-san and store till next batch. Just keep a spare set of O-rings handy and a tube of food grade lube and your golden.
