Yes, That's correct. I like 3 partitions best. You will need 2 draw off boxes and the cut outs in the partitions alternate from one end to the other. Then you will add sap at one draw off box and on a 2x3 pan, sap travels a 12' path (3' x 4 channels) to draw off, getting thicker as it moves along. # partitions is what the older Half Pint pans had, newer ones have gone to 2 partitions so now sap only has a 9' long travel path.
It is good to reverse direction as soon as the channel bottom nearest the draw off gets niter built up so that a plastic spatula has a drag resistance. Then Slowly draw off about 1/4 of the volume in the pan and slowly add it near the new draw off side. Then resume boiling and add new sap at the old draw off side, which is now your in feed side. Moving the portion that was almost syrup helps establish the new gradient faster and helps make lighter syrup. When drawing off syrup, do it very slowly and keep adding new sap slowly to reduce surges.
Dave Klish, I recently bought 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.
