we

we do sell a lot of these for guys that do want to purge the system before adding beer to the hops.

https://www.norcalbrewingsolutions.com/store/Tri-Clover-2-Inch-Corny-Ball-Lock-Gas-Out.html

it gets installed in the bottom in place of the blank cap. We build the 1.5" 2" 3" and 4" TC

When you are using the brink or yeast collector, do you need to have an open vent at the top of the conical? If so, aren't you pulling in oxygen as you dump the yeast/beer into the sight glass/mason jar?

I am thinking you could connect a gas manifold and hook up a C02 tank but I am not sure how you would determine what pressure to set it at to displace the liquid with CO2 (it looks like it dumps pretty quickly with the brink)...

I'll jump in.

I have and use both the brink and the yeast harvester. With CO2 hooked up to either device you DO put CO2 into the fermenter, but not air if you purge adequately, regardless whether you are pressurized on unpressurized. When unpressurized, as long as you have an airlock in place the excess gas will vent without letting O2 in. When pressurized with a spunding valve in place the excess gas will vent when the tank pressure exceeds the value of the spund's set point.

In either case the CO2 input pressure only needs to exceed tank pressure by 1~2 psi to get a quick 'up siphoning' of yeast or dry hops with the brink. When dumping trub or harvesting yeast the pressure differential needs to be reversed, or just let gravity do the work. But when dumping or harvesting you'll need to vent using a gray QD fitting with gas line emptying into a blow off jar to allow the brink or harvester to displace the gas inside. The way to avoid suck back is to create 1~2 psi pressure inside the fermenter and then open the conical's lower dump valve. No air, no suck back.

There is a view right around 2 min 40 sec of what you can expect to see in the kettle when using the exhaust port to vent the oxygen.

Thanks, but I am assuming the lid was off the fermenter when you were filming that? My concern isn't air getting in through the dump port, as your device does a good job at venting that, it is pulling air in through the top of the fermenter when the yeast/trub drops into the jar. Sounds like connecting a CO2 tank at 2-3 psi while harvesting will do the trick though

Gotcha. Sorry I totally misunderstood. Yes absolutely adding a little pressure with a Co2 tank will work. What I do is use my Co2 harvesting kit and let it do it for me.

I got through my first use of the yeast brink OK. Doing a hazy IPA, I definitely tried to do too much hops at one time ended up with a bit of a mess but got through that.

I really disliked not having my sight glass. I guess I use more than I thought to see what's going on in my conical My setup pre-yeast brink was the sight glass, 90, and a valve. I'm thinking about setting up to use the brink like I've shown here. Is the extra 90 between the brink and the valve going to give me trouble?

No, that is how I have it setup. I like your straight sight glass setup. If you are worried about oxygen in the 90 degree elbow, you can loosen the TC at the outside of the valve and purge the yeast brink and 90 degree elbow with CO2 before opening the valve to allow beer to flow into the yeast brink and mix with the hops.

I wouldn't think it would. What's the inside diameter of the 90 degree pipes? Some are larger bore than others, and smaller might have some restriction. Gravity as well as any pressure you have in the tank should take care of it however.

I know what you mean about the sight glass. I've got a mini (~2") one that allows me to mount "dump port, sight glass, butterfly valve, yeast brink" in a single vertical drop with no bends. The biggest restriction is the I.D. of the mini sight glass which can create flow problems with trub dumping or yeast harvesting if I allow it to get too compacted. Cycling the butterfly valve or applying a couple psi of gas to the fermenter seems to get it flowing eventually. Just be patient and be ready to immediately close the valve when flow starts, because it can quickly fill the brink and also blow a hole through the trub or yeast inside the bottom of the conical's cone. If it does that you'll be 'dumping' beer while leaving leftover trub or unharvested yeast in the conical. Just crack the valve open enough that is slowly flows once you get it moving.

The sight glass, 90's, and valve all have approximately the same ID so that shouldn't be too much an issue. If I wait too long to do a dump, especially in a hoppy beer, and everything gets packed down in there I have seen flow issues like you mention with just the sight glass/90/valve.

Okay - disregard that previous post.

For others that may have thought the same thing - here is the solution:

Attach the dry hop filled yeast brink to the conical but do not fully tighten the triclamp. Apply purge gas a few times and allow the purge to exit around the TC gasket. After purging a few times tighten triclamp and voila - O2 free dryhops
I know this is an old post on an old thread but searching hasn't readily revealed an answer

Has anyone actual checked to see if purging with CO2 like this ACTUALLY removes the oxygen? What pressure? How long?

I would appreciate some input from any of the scientifically minded among you - to my mind it would seem that the sudden influx of high pressure gas would make all kinds of crazy eddys that would effectively just make a mixture of air and CO2 unless you did it for a LONG time. I'm thinking of fluids as an analogy

Fill a bowl with milk, then spray water into it and see how long it takes for it to be totally clear with no sign of milk. Maybe this is a bad analogy though.

I want to buy one of these for my new conical for dry hopping, but I'm trying to think of a way to liquid purge it or something, in order to actually be sure the air is displaced.

I only did this once, but I filled the yeast brink with starsan, pushed it out with co2, then dumped out the leftover starsan through the ball lock port, then added hops and purged again.

Yeah I thought of doing that - but you introduce air by opening it to the atmosphere again, so it seems marginally more effective than just purging

I did start another thread on this question as it may have the potential to become a larger conversation about purging small spaces (bottles, dry hops, etc)

I know there is an oxygen free dry hopping thread with some interesting ideas on it, maybe this discussion would be best on that thread too... The internet is a messy place

What is a yeast brink you ask? Here ya go. Its a multi purpose yeast harvesting and inoculating tool that you can also use to dry hop AND O2 evacuate your conical!


Here is a link to the actual brink online

I just watched your video and have to say Brilliant! I also thought of another use which you may already know of. While taste testing my young barleywine I think your product could be used to inject finings into a beer. After injecting just continue to purge with CO2 to lift the finings throughout the beer. I use gelatin and this should work.

yeast, finings, and priming sugar solution all seem like great options
