I've used my Cannular filler in three canning sessions now and I'm having trouble getting it configured such that it doesn't have quite a lot of overflow during the fill process, so I wanted to see if others are using it and have any tips that might help.

Could be my settings, could be I still have too much foaming, or, if having a fair amount of foam overflow is to be expected, at least I'll know I'm not doing it wrong. I just get the sense that with some tweaking it could be a lot better.

For background, I did the calibration steps per the Kegland video and instructions (both the manual and the instructions on the device itself), i.e., I made a 100 mm mark on the gas post, filled a glass of water to that mark, let the pressure stabilize as much as it seemed it was going to, and hit the calibrate button. The video vs. the instructions are inconsistent as to whether or not you should have the liquid post in the glass when doing this, but that probably doesn't make a huge difference. In my latest calibration I had the liquid post in the glass.

For reference, here are the settings from the Rapt portal:
  • Empty Pressure: -0.014718762598931788
  • Calibration Factor: 0.0108580831438303
  • Min Fill Rate: 0
  • Fill Timeout: 0
  • Temperature Offset: 0
500 ml Can preset settings:
  • Purge time (seconds): 3
  • Wait time (seconds): 0.20000000298023224
  • Fill Height (millimeters): 130
And in terms of how I'm connecting the keg to the can filler, I'm using a jumper consisting of a 6-foot length of EVABarrier tubing with a Duotight ball lock connected directly to the keg on one end and a Duotight ball lock with the poppet removed (per Kegland's recommendation in their video) on the other end. I also removed the poppet from the carbonation cap on the can filler, again per Kegland's recommendation. The pressure on the keg is 11 PSI.

For the fill height I've tried everything from 120 - 150 ml and in terms of getting the can filled all the way to the top and avoiding the dreaded "fill stopped due to lack of progress" error that happens for me on lower fill heights, this seems to be the sweet spot.

But, here's a video of what that looks like in terms of overflow (no audio, sorry about that):


The overflow is basically all foam. When I set the fill height to 140 or 150 mm I start to see actual beer overflowing.

But that still seems like a lot of overflow to me. When I manually fill a glass through the can filler, once the lines are cold it isn't an excessive amount of foam; it just looks like a good pour with what I'd consider a standard amount of head.

What I was going to try next was fill a keg with plain water and see if I can even get the thing to fill a can with water to the top with minimal overflow, because as of now when filling with beer I either have to accept the amount of overflow demonstrated in the video, or get a fill that either errors out or doesn't fill the can enough.

And while I'm complaining, I also find it pretty infuriating that this hose slips forward and eventually pops off (with the catastrophic wall spraying you might imagine) while you're filling cans.

If anyone has solved that issue with a particular small clamp that fits in that tight space or via other methods it'd be great to hear about that as well.

That's probably WAY too much information! :) I'd appreciate any troubleshooting tips anyone might have or hearing what experiences in general people have had with this filler.

Thanks!
 
I don't own one, but :) Maybe consider it like you would if you were serving from a keg into a glass, and the glass was overflowing with foam?

* Verify keg psi is set about right, something in the 10-12 psi range perhaps
* For kegs, you'd normally have a specific length of serving line, to slow down the beer, based on the line inner diameter - check an online calculator and see if your line length is long enough
* Check connections for restrictions, bad O-rings, anything else that could cause foaming issues
* Consider reducing the flow rate, even if it's just a band-aid maybe it'll get you there for now

I see faucet on the right side of the video so it's likely you know some or all of those things. Maybe approaching it in a similar manner to getting too much foam from the faucet would help?
 
Thanks for the ideas!

Yep, that's what I'm doing more or less, but when I fill a glass through this thing it looks decent. Then again if I kept filling the glass until the foam got pushed out I suppose I'd be seeing exactly this, so that's a good head check. :)

Yep, 11 PSI so we're good there.

Inside my keg I have 5' of 8mm ID EVABarrier tubing from the keg to the faucet, and I'm using 6' of the same tubing for this, so I was guessing that's OK but good call on checking the math.

Thanks again for the sanity checks. Serving from my keg is definitely not too foamy (other than the usual issue with the first pour being a bit too foamy since the faucet is warm) so in theory all this should be good, but I really appreciate all the troubleshooting suggestions! Definitely gives me some things to work with.
 
Yeah sounds like you have a good handle on that stuff. Could a quick disconnect be at fault? Some kind of mismatch between what's built into the Cannular and what are using from your own setup. Spring force issue where one side doesn't want to open up very far, and it's running through something like what happens if you open a picnic tap just a tiny bit (all foam instead of slow flow). I recently replaced a bunch of springs that came with some generic keg posts because they were basically too long and didn't compress like they were supposed to. Solved a lot of foam problems I was having.

Thanks for all the ideas! I'll definitely be tracing through all this to see if I can maybe dial it in better and particularly appreciate the thoughts on the checking the springs. I also might just RDWHAHB and accept some foam losses so I don't lose sleep over it since the end result in the can is good. As with most stuff in brewing I'm sure it'll get better with more tweaking and repetition. Thanks so much again for the suggestions and helping me think through this!
 
Did you end up getting it working? Where did you get the Cannular btw. Been looking for one
 
Well, I got it "working" in the sense that I wind up with full cans of beer and am capping on foam so the end result is good, but there's still a fair amount of foam overflow I need to keep working on. I think the filler itself is doing what it's supposed to do for the most part so I need to experiment a bit more with line length and maybe pressure. But in general I'm happy with it.

I did order some small clips to try to clip the hose coming out of the beer line that I pointed to in the previous post so it doesn't slip off over the course of a canning session. Haven't tried any of them yet but I'm hoping that'll fix that issue.

I got both the filler and the can seamer from MoreBeer -- I had to wait a while since they were both out of stock when I ordered (pulled the trigger when both were on sale), but they eventually showed up. From what I understand they're still having trouble keeping them in stock so I must have just gotten lucky a few months ago.
 
Someone in a thread on Facebook about the can filler said they had good luck reducing foam by reducing the CO2 pressure on the keg to like 3 PSI, so hopefully that'll work for me as well.
 
I having the same issue, excessive foaming. I've basically wasted a keg of beer to try to get this filler dialed in, but I'm having no luck at all.

Ugh that sucks. Sorry you're having trouble as well. My next run at it my plan is to take the main gas line off the keg (my normal serving pressure of 11 PSI), release the pressure on the keg, and then attach a SodaStream canister with a mini regulator so I can start with a super low pressure of like 2 PSI and see how that goes, increasing as needed. If that doesn't improve things substantially I may have to give up and get a Duofiller or just use a beer gun because I don't have the patience to fight with this thing.

I will say the cans I filled for a competition got good comments on the firmness of the can and carbonation level, but I wasted a lot of beer in the process.
 
That's one of my concerns for the competitions—that the beer will lose carbonation. I just don't have the patience to waste kegs of beer to get it dialed in.

I usually fill from the tap and then can, but I bought this to save time canning beers and filling the cans properly. It's not looking promising, that's for sure.
