I really need some advice on how to fix my foaming issues because I’m out of ideas.
I’m using a SS Brewtech 20-gallon brewmaster edition bright tank to carbonate seltzer style products made with 6%-11% fruit juice. I’m able to fill the first 20-25 cans, but then the amount of foam increases dramatically to the point cans are almost entirely foam.
Here is my process: Mix and chill the ingredients to about 33-34 and pressurize to roughly 12-14 psi in the headspace for about 2 days until the pressure stabilizes. I then connect to my xpressfill 2200 filler.
During the time that I am filling, I turn up the CO2 through the carb stone to backfill pressure in the tank and prevent CO2 breakout as I am filling the cans. I have tried using both a 5ft 3/8" filling tube and a 25ft. 3/8" filling tube with no significant difference. I also check the temperature of the liquid once it reaches the can, and it is still around 33 degrees.
The surprising thing is that after this major foaming begins, I test the liquid from the sampling port. It will come out as straight foam as well. This makes me assume that the source of the issue is inside the tank and not from my filling process.
Last time this happened I decided to shut the butterfly valve and let the liquid sit for a day before testing the liquid from the sampling port again. A day later, it was still just straight foam despite the sampling port being below the level of the liquid.
I am making 19-gallon batches and end up with 3-4 gallons max of usable product. Any thoughts or recommendations on how to fix this issue?
