In line aerator, anyone tried this?

Anyone built this before?

An inline aerator but so you can add bottled oxygen as you transfer to the chiller.

Seems like a good idea and would save you having to oxygenate your wort afterwards.

I recently got one of these second hand off eBay which has an oxygen barb and stone in 1/2" fitting. The acutal fitting doesnt suit my needs so happy to post a pic tonight when I get home. Might save a lot of building time.

HAHA Yeh Im a bit of a gadget freak..

Haven't tried that, but I did undertake an online aerator project a while ago, and it only took 30 seconds. (The time taken to heat the end of a paper clip and stick it through the wall of a plastic tube. Venturi effect; seems to work okay.)

Got a link?

I've never found it THAT hard to inject the oxygen later on. I mean you stick the airstone in the wort and wait a minute. Not trying to put anybody off building one or anything, just seems like it might be solving a problem that doesn't exist.

A lot of commercial operators aerate in this fashion.

Will work in a HB situation, if that floats your boat, but doing it any other way on our scale will work just as well.

I would suggest doing it post chiller. The solubility of oxygen at high temperatures is very low and you will just have bubbles. I don't know whether things would sort themselves out going through the chiller and then dissolving, you may just end up with bubbles staying in the chiller. Of course doing it post chiller means sanitation needs to be considered and you want it easy to be cleaned.

It is done at many breweries post chiller but things are more difficult to do uniformly on large scale systems. It would be far from the first gadget I install, especially if you already have a stone.

This is a very lengthy discussion.

But I seem to recall that in the end the consensus on one discussion (which I can't seem to find) was that best results are obtained from just one pin/clip hole in plastic tube, near where the tube joins the tap (not at the bottom end), as long as the tube fits over the tap and not into it. This creates the pressure difference (ie, going from smaller diam to larger diam) and a hole about a centimetre below the tap will then suck in the air.

@ Black-labb..Yes the idea is definitely to do this post chiller. You turn the oxygen on once your fermenter is half full.

@STM... The method you describe is a simple venturi setup used to suck air flow into the wort. A good idea if you just want to add air. The method I link to above is for injecting oxygen from a bottle into the wort stream.

@Slash2200 You have a point it is easy to just stick an airstone into a fermenter for a minute. But I like the idea of being able to start draining to the fermenter, then once the ferms half full, turn the oxgen on pitch my yeast and let it continue to fill.

Im also assuming you would get a much better mix of oxgen in the wort doing this method, (Although just an assumption and would like to see some proof either way)

Arrr yes, thought you guys might have done something different, but that's basically what I used when working on big hydraulic tanks, jam a venture in the top with compressed air holding the fluid in so you could rip parts off and not have to drain all the oil..
Might whip one up.

Hmm i'd love an inline carbonator though!
