I’m converting a still to run under vacuum and need some kind of receiving flask (10-40L) for super cheap to run under vacuum. I was thinking an ideal system would be a few kegs run inline in an ice bath.
I’m wondering if anyone has any ideas for fittings on the keg. I was worried tacking a vacuum port on the surface would compromise the structural integrity of the keg. Is there anything off shelf I could use? Is it as simple as cutting off the top fitting and welding on a cap with a downtube and takeoff valve?
Or if you have ideas for something cheaper that I can just go and buy I’d be super happy to get on that!
