This was our last boil of the season and the finish pan had so many bubbles/foam in it, it almost overflowed. Could not control it with defoamer. The only way to stop it was shut the fan off and kill the fire. What happened?
Overflowing pans?

Late season sap can do that.Originally Posted by Sunnyacres

Likely a sugar sand build up on the bottom.
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.
How deep are your pans? Are you using std defoamer? When was the last time you had boiled and was the sap kept cool?
You may have encountered some ropy syrup? What was the color of the bubbles?

Pan is 7” deep and running 1.75 deep. Yes using std defoamer from last year. It has worked all season. I had some ropey syrup at the beginning of the week but boiled that thru. Bubbles looked like normal syrup bubbles when we are close to syrup but I checked every partition and was not close to syrup. We just lit the fire less than 45 minutes when this happened.
Overflowing pans?
Had the same thing a couple years ago. Usually means season is over. No matter how much defoamer I put in nothing happened.
As in Atmos? Karsher?
Either way, if you're using a standard (non-organic) defoamer and this is happening...you're likely at or near the end.

So we dumped everything from flue pan and syrup pan in buckets thru filters cleaned everything and starting finishing in the syrup pan and it’s boiling like normal. Thought the syrup pan was going to have a thick layer of of buildup on the bottom but it was actually pretty clean well the season is over for us pulled Taps cleaned everything and just finishing the remaining pan juices.
Thanks for the info and picture. To me that just looks like syrup way over temp? But thats just my read of your picture. Yea I would have been adding defoamer too!
