Syrup production

Below is a list of points to check when making maple syrup.
• Monitor the water level in each of the pans.
• Monitor the temperature in the chimney.
- The reference temperature of the chimney to keep in mind is above: 850 °F (450 °C).
- LAPIERRE EQUIPMENT suggests using this reference as the minimum starting temperature.
- This reference will be used to determine when combustion chamber fuel refills are required.
o A temperature below this reference indicates that a refill is required.
- Evenly distribute coals and embers with a poker, load a fresh load not above the middle of the door window.
- Monitor the temperature of the chimney regularly.
- IMPORTANT | At all times, the chimney temperature must not exceed:
o 1000 °F (540 °C) for VISION equipment with STANDARD or DELUXE pans,
o 1200 °F (650 °C) for VISION equipment with ACCORDIAN PLEATED pans.
• Regularly check the Brix concentration of the syrup at the drawing valve.
5.2.3

Changing the syrup pan

Below are the instructions to follow when changing the syrup pan.
• Check the condition of the gasket between the pans and the combustion chamber.
• Check the insulation joints between the pans.
- IMPORTANT :
o a syrup soiled gasket must be cleaned,
o a blackened or damaged gasket must be replaced immediately or very quickly.
• Check that there are no concentrate leaks under the boiling pan.
• Check the boiling rear pan for cleanliness and accumulation of sugar stones.
• Before replacing the syrup front pan, make sure the fireproof bead is fully raised to its position.

5.3 EVAPORATOR SHUTDOWN

Below are the instructions for shutting down your evaporator.
• Make sure you have a minimum reserve of 2 hours of concentrate or water.
• Stop feeding the combustion chamber.
• Although the coals burn out quickly it should be noted that the heating of the pans will continue for some
time due to accumulated heat in the evaporator.
• After 2 hours, turn off the water or concentrate supply to the evaporator.
• Close the valve located between the boiling rear pans and the syrup front pan. For the 18 x 48 in. mono pan
(single pan) close the opening between the rear accordion section and the front section with the supplied
plug.
