Well I made some progress on ther AOF system. After the first boil I was having trouble with getting the outer syrup pan partitions to boil. I changed the 1/4" pipe AOF nozzles out to 3/16 drilled pipe plugs. This should keep cool air to a minimum and hopfully cause more turbulence. I also reworked how the air enters the dampers. Hope to test boil this weekend so I am 100% when we get the next run.
