High-Viscosity Polymer Dispersant for Vacuum Pans & Crystal Pans
"Disperser S60 is your pan’s best engineering upgrade. Cut viscosity. Boost circulation. Crystallise faster."
Vacuum pans boil dense massecuite - a complex suspension of growing sugar crystals in high-purity molasses - under vacuum at 55–70°C. As the massecuite thickens to 90–95% dry solids, surface tension rises, thermal circulation stalls, and CaSO₄/CaOx begin depositing on pan walls and heating tubes. The result: extended boiling times, poorer crystal quality (high ICUMSA), incomplete molasses purging, and contamination of sugar with iron oxide from boiler condensate directly impacting export grade and premium pricing.
Sludge volume reduction
Acid cleaning interval extension
Zeta potential max repulsion
Blowdown iron (vs 8–12 ppm untreated)
Disperses fine solids and prevents crystal agglomeration to maintain free circulation.
Reduces insulating deposits on pan walls and heating tubes for faster evaporation.
Produces purer, brighter crystals with lower ICUMSA and better centrifugation performance.
Extends operating cycles and reduces acid cleaning downtime and cost.
Controls iron oxide contamination from condensate, protecting sugar colour and purity.
