Oxygen reg & stone

fakr · November 06, 2012, 06:20:29 PM

Honestly, I've seen a solid 2 day lag when forgetting to use oxygen. On top of that, fermentation wasn't as aggressive as usual either. it took the krausen a couple of days longer to hit it's highest.

This was observed when pitching into 20C wort using the same type dry yeast, the fermentation chamber set to a constant temp, same OG, etc.

Quote from: "sdixon"I have been thinking about getting an aeration stone as well. My lag times drag on sometimes... opening myself up to potential contamination.

That's my biggest reason for getting this.

I have a spare SS T fitting that I think I'm going to retrofit to the end of my CFC for aeration. I'm going to install the aeration stone in one end of the T and blast 02 in it as wort passes through it, instead of fishing the stone on the end of a hose to the bottom of my fermenters.

I'll have to figure out how to seal it etc.

Interesting idea...

Essentially what many of the commercial breweries do.

That's what I'm hoping to eventually do as well. Will be interested to see what you put together.

Ok, I just remembered that I have a 1/2" end cap that I could use to thread into one of the holes of the T. I bought 2 or 3 of them to use as plugs for holes in kettles, etc.

If I drill a hole in the end cap, the same size as the SS tube coming off the aeration stone, that would be a start....Could probably just silver solder the stone in place.

I'll check when I get home to see if there is enough clearance. If so, then I can provide a solid parts list for making one of these puppies.

Awesome.

Well, unfortunately, I'm unable to fit my stone in a half inch Tee. I think the stone is a half inch and just won't go past the threads. I'll have to either think of another solution, or look at buying a different stone. That's disappointing.

What about using a bigger diameter T, and then use reducers on the ends to connect to the 1/2" fittings? You have Pinnacle locally, should be something usable there.

fakr · November 07, 2012, 07:18:50 PM

yeah, good point Kyle, thanks. A 3/4' T would definitely hold the stone. I'll look into it.

Ideally, a longer, more narrow stone would be ideal though.

This sort of what youre talking about fakr?

Seems like some good buys for oxygen systems here too..

After a super long lag time with this winter warmer im thinking an oxygenation system might be a good idea.

fakr · November 07, 2012, 10:48:29 PM

Thanks Dandy, that's exactly what I was looking for. screws right into a 1/2 ntp. Think I'm going grab one.

Yeah think I'm going to try this as well - I have O2 from a kit we always take along diving, and a stone, but I really like the stainless rod in the link you posted Dandy...

Fakr I'd be interested to see how much foaming you get with the stone / tee setup out of your CFC. Sounds like a nice setup. I know Dean had used a small piece of tubing with some small pin holes in them to aerate wort coming out of his CFC. I always wanted to try that as well...

Fakr if you order the 1/2 NPT stone, lemme know maybe order 2 and I'll go in with you?
