Hi brewing community!
I'm in the middle of a filtration right now and having some trouble to perform it. I began 1h30 ago and I'm just half way through it.
We purchased a plate filter and this is my second filtration. First one was a mess as well.
So I have 4BBL of slightly hazy undryhopped beer to filter. It's been conditioning for 3 weeks so no heavy amount of yeast.
I picked some medium brilliant sheets, so 8-10µ. There are 16 of them, on some 40x40 frames.
Here's what I've done.
FV and BBT are balanced together at 1.2 bar (18 psi?). I began by performing a sanitation of the filter, hoses and pump and rinsed it with 85°C water. Once the rinse done, I pushed the hot water with hazy beer with pump off. Once hot water was out and beer fulled the system, I switched the oulet Tee to the BBT. Once pressure had been balanced, I started the pump slowly (around 12HL/h). At the beginning it went pretty well, except the output hose of the filter that was showing half beer half foam through the sight.
But quite quickly, the output flow went to slow down, and right now, bright beer is dropping rather than flowing.
I'm trying to understand what went wrong.
Did I pick a too fine sheet to begin?
Was I supposed to push hazy beer with pressure instead of pump?
Did I turn the pomp on too soon?
For precision, the sheets are in the right sense, I double checked.
Right now, inlet pressure is 2.2 bar for a outlet pressure of 1.2 bar, so I guess the sheets are completely clogged.
Does anyone have some ideas?
Thank you,
Guillaume
