I just shut down after 10 hours after boiling. I boiled 107 gallons of sap and am left with about an inch in my pan with is about 5 gallons. I have a 2x4 divided and was wondering what you pros thought. I never blocked off the dividers cause my original plan was to just finish on the turkey fryer in the morning. I was about to go to bed and I thought why couldnt I just add the sap I get tomorrow ( I am planning on about 40 gal ) to my pan and start my evaporator up again for another 4 or 5 hours. Would this be a better route or just finish what I have tomorrow and boil again in a couple days. I have my pan set up as a continuous flow but havent got to actully do a good flow because not enought sap.
