We have developed a new style syrup pan that allows very fast and simple reversing of the flow in the pan.

Background:
As sap concentrates into syrup, very very fine "maple sand" percipitates out of solution and collects on the bottom of the syrup pan, mostly in the last channel.  If the sand gets thick enough, heat transfer slows down and boiling slows.  If the sand gets real thick, the boundary layer between the pan and the sand will scorch, imparting a burnt flavor to the syrup and making a mess that is very difficult to clean

Solutions to the problem:
Solutions to this problem have been tried for years. The simple way is to let the fire die, take off the pan and clean it. Lots of lost time.
A reversible pans was then developed. The pan had ports on both the right and left sides that would connect to the float box from the flue pan. In order to reverse the pan, you had to let the fire die down enough that you could physically lift the pan off the arch, rotate it 180 degrees and re-connect it. If was also recommended to remove a lot of the sap from the pan to make it lighter and reduce the risk of a spill or scalding splash. Once the pan was reversed, new sap coming in from the flue pan would partially loosen and disolve the layer of sand. A few more hours of boiling could be done before the problem developed again.

Our solution:
we have developed a new design that can deliver sap to the front or the back of the syrup pan just by opening one ball valve and closing another. The pan has two syrup draw off points, one at the back and one at the front, both on the same side. Reversing the flow takes only a few seconds.
