I'm not seeing it ??Originally Posted by JeffB
Before we get too far into troubleshooting, I don't recall seeing what evaporation rate you're hitting. At 1 1/2" depth, I'd expect you to be at 16-20gph or so without much blower, 25ish with the new blower. How far off are you?
What size wood are you burning (and what is coffee dry wood ???)
In your initial post you mentioned that you sweetened the whole pan. Changes in depth are the culprit here. Every time the depth increases or decreases, you move sap back and forth within the pans, mixing the sap and averaging out your concentration. Pick a depth that you are comfortable with an stick with it. The gradient will reestablish itself over time as you keep adding raw sap at the back.
