7.7 SOLID DEPOSITS (STAINING) IN THE PANS

It is important to understand that the solid deposits or staining problems vary significantly from one sugar bush
to another, from one year to another, and even throughout the season.
The reference number of Brix degrees to be used is: 42° Brix.
In the BOILING pan (accordion pleated)
Solutions
1. When the evaporator is in operation, check the sugar content of the concentrate entering the hot float. Ideally,
the sugar content should be about 42 °Brix.
2. If the sugar content is higher, reduce the concentration level at the concentrator outlet until the staining
problem is solved, or the sugar concentration is 42 °Brix.
In the SIROP pan (plate)
Solutions
Reverse the flow regularly, or as soon as any solid deposits appear.

7.8 THE FLOAT DOES NOT CLOSE COMPLETELY

If one of your floats leaks or drips, proceed with the following troubleshooting tips.
Cold float, boiling pan
Solutions
First check the mechanical condition of the valve.
• RODS: Is it straight or warped?
• PISTON: Is it flat in the valve or at an angle?
• O-RING: What is its condition?
- Lift the lever that connects the float to the water inlet valve.
o The water stops flowing with a small amount of pressure. Simply readjust the float using the adjustment
rod that connects the float to the lever.
o The water still flows despite the following conditions.
✓ A concentrate basin base 8 ft. (2.4 m) higher than the float valve.
✓ An O-ring in good condition or replaced.
✓ The application of a large force on the valve.
In this case, the valve seat must be replaced with one of the following:
❖ EV406-011824S1, for floats with a 1.5 in. (3.81 cm) connector,
❖ EV406-011832S1, for floats with a 2 in. (5.08 cm) connector.
✓ The height from the base of the concentrate basin to the valve is less than 8 ft. (2.4 m) than the float
valve.
✓ The application of a large force on the valve.
In this case, the O-ring of the valve must be replaced.
