The application of power ultrasound (PUS) to sugar processing is accompanied by reduction in viscosity of molasses and masscuites and control in scale formation. The FT-IR and SEM analysis of the scale implied that the PUS treatment suppresses the formation of calcite crystals (hard) and prefers vaterite; a thermodynamically least stable (soft) polymorph. The results are consistent with the Ostwald's repining principle. The laboratory experiments coupled with commercial trials were confirmed to be beneficial for process control and significant energy saving.

Abstract


The application of power ultrasound (PUS) to sugar processing is accompanied by reduction in viscosity of molasses and masscuites and control in scale formation. The FT-IR and SEM analysis of the scale implied that the PUS treatment suppresses the formation of calcite crystals (hard) and prefers vaterite; a thermodynamically least stable (soft) polymorph. The results are consistent with the Ostwald's repining principle. The laboratory experiments coupled with commercial trials were confirmed to be beneficial for process control and significant energy saving.
