Over 10 years ago I bought some tanks and barrels from a producer who was retiring from maple, who did 400-600 gal a year, all filtered on flat filters. He had a bunch of large filter pans on legs. I think they were 3'x3' or close to that. He likely had 6 or 8 of those set ups. He never used a filter press. I do not know if he used filter aid, but his syrup was nice and clear in the bottles I saw.
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.
