OPERATING THE EVAPORATOR 

NOTE:  When operating the evaporator be cautious of hazards such as hot surfaces, hot liquids, sparks, and exposed 
flames.   

NOTE:  You must be aware at all times of the level of sap in all compartments of the pans.  If the level drops too low you 
can and will damage your pans.  If there is too much foam you risk damaging your pans. 

NOTE:  If you have purchased a scoop or skimmer, do NOT use them to push sap through the evaporator.  Doing so will 
change the gradient in the evaporator. 

1.

 

Check the evaporator 
a.

 

Make sure all sap sources are flowing freely i.e. not frozen. 

b.

 

Ensure defoamer is usable. 

c.

 

Ensure all fittings are tight. 

d.

 

Make sure all valves are working properly and the floats are properly positioned. 

e.

 

Clean the flues with the flue brush every 8 to 12 hours of boiling.   

f.

 

If using a wood fired arch, ensure the open area in the grates is clean and free of material.  If necessary, 
remove ashes from below the grates.   

g.

 

Open stack covers, cupolas and thimbles. 

h.

 

Open condensate drains. 

2.

 

If this startup is for a new evaporator or for the first time of the season, go to the Section titled MAKING SYRUP.   

It is recommended in order to minimize the sugar sand and niter, the flow in the syrup pan be reversed daily or when it 
is noted the bubbles from boiling are drawn back down into the compartment as they break (appear like boiling mud).  
The following are the instructions for reversing the flow in an PATRIOT evaporator: 

 

SYRUP PAN REVERSAL 

Flow reversal in a PATRIOT evaporator is done by changing the position of a stainless steel plug, two valves, the Z-arm 
and hot sap float.  These plugs control which side of the flue pan the fresh sap enters and which side of the syrup pan 
will be the finishing side.  The diagrams below illustrate the two possible flows in the pan set. 
 
RIGHT DRAW OFF
