Back when I used a flat filter set-up, I filtered it in small batches off the evaporator. Then brought the syrup back up to about 185 and bottled it. In the filtering process it cooled to maybe 130-150 or so and it must be at 180+ to bottle it. Be careful not to heat it over 190 or you will form more sugarsand and thus get a cloudy finished product.
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.
