There are float boxes on the back of the evaporators that maintain a continuous level in the evaporator pans, and are gravity fed from the storage tanks. As the sap flows forward in the evaporators, more and more H20 is removed from the sap until at the front of the evaporators where the syrup comes off it has lost most of the water and it's a thicker sugary liquid. Syrup needs to be brought to 221F to be syrup. As you know water boils at 212F but syrup is like oil and has a much higher density and boiling point. We use two methods to make sure that we are pulling batches of syrup off. Temp. is one and a hydromiter to measure density is the other. As the batch is drawn off we keep close track of both and discontinue drawing when temp drops and hydrometer drops below syrup density in the drawoff pails. Size of batches vary a great deal. Big batches yield around 15 gal. of syrup. Small ones can be 3-4. If the depth of sap/syrup gets too low we run the risk of scorching the syrup. The floats are set to maintain a minimum of 2.5" depth in front pans. There are times when the air is clear, the fires burning hot, that we have to ladel some cooler sap from the rear to close to the front to keep the syrup from getting too hot during a drawoff. There is a lot to know and understand. The amount of wood in the fire box and barometric pressure have a lot to do with the size of batches. the time laps between batches once the first one comes off range from an hr. to a couple on a slow day. These figures are per evaporator. We have two evaporators running and they both vary. Loren

Today's Featured Article - Earthmaster Project Progress Just a little update on my Earthmaster......it's back from the dead! I pulled the head, and soaked the stuck valves with mystery oil overnight, re-installed the head, and bingo, the compression returned. But alas, my carb foiled me again, it would fire a second then flood out. After numerous dead ends for a replacement carb, I went to work fixing mine.I soldered new floats on the float arm, they came from an old motorcycle carb, replaced the packing on the throttle shaft with o-rings, cut new ga
