Hey guys,
A few brews ago I bought a blichmann plate chiller, absolute game changer. 15 total minutes to get from boiling to pitching, though I use chilled glycol instead of tap water.
Immediately after I pitch my yeast, I pump warm water with pbw through, and then I pump some starsan through it. Then I let it sit on it’s side to drain and dry.
When I was preparing and doing prep-cleaning for my most recent brew, the output of the plate chiller was shooting out what looked like hop material, possibly even mold? I ran starsan through it multiple times, maybe even like 10-15 times, and every time I did it, more green solids came out. After a while of continuous pumping, the liquid coming out would eventually be clear, but then when I did it again more solids would come out.
So my questions are: what did I do wrong? What should I have done differently? And what should I do now?
