Welcome aboard. My first suggestion is to put Wisconsin for the location, It helps others better know how to answer some questions.
At this point, if you had a faster way to boil, how many taps might you consider? If thinking a small maple rig, there are lots of choices. A good way to start is to look for a small used rig where a producer has out grown it. Best prices are now and as the season gets closer the prices go up. I suggest a welded pan(s) or lead free soldered. Rigs made between1990 until the late 90's can have lead solder.. If by chance you get a lead soldered evaporator, do not clean the solder to a shine, leave a dull coating on it.
Even if you get an evaporator rated for 100-200 taps, you could build a reverse osmosis machine which would remove much of the water to reduce boiling time.
Again, welcome!
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.
