I also tried 1 sq. foot of 30 x 30 and it was a little better when hot draining in the case of a plate chiller. If you try cooling in place with an IC, forget it. Cold break + pellet hops = concrete wall on the mesh.
Thanks for the reply. I was planning backflushing, so I am not planning on completely getting rid of 100% of all particulates, however I don't want to irreversably damage my plate chiller, especially while I am using it.
So perhaps something a little smaller than 30x30 sounds like it would work? Maybe 35x35 or something?
