Rotary bottling machine

[john luc]

I am looking at building a small rotary bottling machine and have more or less worked out the workings except for one area. I will have the co2 coming from the header space in the bright beer tank and feeding into the header space of the rotating bowl as well as the beer coming from the same BBT into the bowl. Both will need a swivel connection but if fitted separate to the top of the bowl they of course will just twist around each other. Do not have access to an engineering shop to have some thing special made so would appreciate any advice.

I would like to help but would need to see a sketch or 2 of the problem to throw a few ideas into the mix.

could you take a photo of a sketch and post it here ? failing that you could email me the photo.

I am using a 30 Liter keg with 12 bottling heads connected. Each beer outlet pipe coming from the bottom of the keg is 10mm S/S with an I.D. of 8mm so with all pipes draining I need a minimum of 28mm I.D. pipe feeding beer from the BBT in through the top to keep a constant flow of beer filled in the keg. The 12 CO2 gas outlets all come out of the top side of the keg to feed each bottle.
I need 1 10mm connection feeding the CO2 from the BBT in through the top of the keg and 1 35mm connection also feeding beer from the BBT. Since both the CO2 and beer in pipe are coming from a fixed position BBT they need to swivel with the rotating keg and thus would just twist in to each other. The outlet on top of the keg is 50mm I.D. so a swiveling 50mm connection which has 2 connections fitted to it,one 10mm for the CO2 feed and the other a 35mm (approx) for the beer feed would mean the both connected pipes would rotate side by side and not twist . So I don't suppose I could drop in to my local B&Q and pick up one of these.

what about having the co2 pipe inside the 35mm beer feed ?

I had considered that and put it to one side but might go back to it again. I suppose I could have the CO2 pipe come direct from inside the BBT and then into the keg. Might work

Also a john guest fitting (plastic collet etc) allows liquid through whilst rotating 360 degrees without leaks. if you could get a large enough one.
