Does anyone here know what professional breweries use as their "airlock"? I cant imagine they have blow-off tubes sticking out of each massive tank. Are they all equipped with a spunding regulator or are they doing something else?
Cool
Yeah and I see why you need plenty of ventilation!Cool
Would be nice to capture all of that C02!
Do they have to purify it before re-use? I would image there is some sulfur, hop compounds and whatever else the fermentation produces.Sierra Nevada recovers CO2 and has since 2005.

It's quite interesting how much Ken invests in a sustainable brewery. He's an amazing guy. It's not unusual to run into him downtown...

They have honking big stainless steel blowoff tubes dunked into a five-gallon bucket of Star San. Or some smaller version, depending on the size of the fermentor.
It's crazy that its so low tech, compared to their other gear. Not that it has to be high tech, its just interestingThey have honking big stainless steel blowoff tubes dunked into a five-gallon bucket of Star San. Or some smaller version, depending on the size of the fermentor.
Yeah, I have a Unitank and i use a blow-off tube. It's just a crude part of my setup that I had assumed larger breweries would have solved for differently by now.Some are high-tech, with CO2 capture and so forth. Most just do what we do: use a blow-off tube. At that scale, an airlock is not practical. And as Yooper says, it can get messy.
Imagine the amount of vodka in that thing!I want to see a giant air lock on a 900 bbl fermentation tank.
