A long story on my first season. I bought a used half pint in real nice condition. I got is set up, firebriched it and was ready. I already had plenty of dry wood.
Then I started tapping trees. I tapped 27 at first and waited a few days for the first sap flow. That went well and I added more taps and repeated that until I had 70 taps. Then the trees really turned on and I had to boil for 20 hrs straight and still fell behind. I ended up having to dump some spoiled sap because I had more good sap and could not boil it all. That was just 70 taps. I see no way for a half pint to do 150+ taps unless you have an RO, even then it would be a long boil. My average boil was 6 GPH evaporation.
I sold that evaporator and bought a used 2x6 with drop flues for seasons 2-4. With that I got 24-27 GPH.
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.
