How many taps are you running and do you use an RO? The size is related to total tap count and your ability to process. I am set up for about 1000-1200 taps and I can process about 2000 GPD without working all night (At times in the past, pre-RO, I once boiled hard 4 days in a row while at the same time selling almost 1200 gal of sap. I boiled an 18 hr day, then 2 days at 21 hrs each followed by another 18, that was when I decided to buy an RO).
I have a few SS tank but I still haul in totes from my leased bush, hauling two totes. For tanks I have a 415, a 545, and a 300 that I use for sap. I also have a 200 and an 850 I don't use but could, then my head tank is 150 gal and my permeate tank is a 1000.
I wash each tank shortly after it is emptied each time. I thus like the multiple smaller tank approach. If you have just a 1000 gal, and can't empty it and wash it every day, things will head south on your syrup.
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.
