Going back to Proctor's reported experience from the 2018 season, they concentrated to 34-35%, cooled it to 23-24F and I think I read that they only boiled 2x a week, anyone, correct me if my old memory has again failed. The person who works the sugarhouse, and apparently has for years (along with Dr Tim) actually got weekends off.
The final results were a product that was great tasting and the lightest color ever.
I watched a news report which is available on this sight, posted by Dr Tim Perkins about this.
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.
