How much syrup do you filter in a day, if you use 4-6 cone filters? Maybe it's time, if you prefer staying with felt or Orlon filters, that you should make or have made, a large flat filter rack to use the largest flat filters, they will filter way faster and easy.
Years ago, I bought some tanks and small stuff from a retiring producer. He had a 4x14 oil fired evaporator so he did a lot of syrup. In his sugarhouse he had about 8 or 10 30"x30" flat racks that he filtered with, with a square tank under each.
Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
