Hi all,
I've got hazy filter #5 running through my 40 plate 40cmx40cm plate and frame filter press.
It is NOT:
-pads put in incorrectly. Trust me.
-bad pad lot...I share orders with other local brewers who have no problems from this lot
-yeast mutation....happening across 4 strains, all 1st-to-4th generation
-high protein content in new barley lot. Again, other local brewers using same supplier.
-mash technique, boil, cold stabilization post-ferment, etc....nothing has changed in our SOP over three years and suddenly every filter is hazy.
What I think it IS is f@cked-up filter plates or gaskets that are cracked or something. I've been talking with Dave at Glacier Brewing who had the same problem a few years back and he replaced all the plates and gaskets and the problem went away.
So here's what I'm asking for help with: can anyone out there think of a way to pinpoint which of these plates is bad so I don't have to buy 40 new plates at $60 a pop just to replace one bad one? I really can't think of how to locate the bad plate(s)!
Any help appreciated!!!
