7th ESST/VDZ Conference and Exhibition 2022

Sugar cristals
Centre des Congrès de Reims
Liquid Measurements

The European Society for Sugar Technology (ESST) and the Verein Deutscher Zuckertechniker (VDZ) organize the 7th ESST Conference for sugar technology bringing together sugar technologists from all European sugar producing countries.

Vaisala with it's partner Zutora and distributor Galabe welcome you to their booth no 52 to discuss Vaisala K‑PATENTS refractometers and SeedMaster SM-4 which provide:

  • Increased quality of liquid and crystal sugars 
  • Sugar products precisely according to recipe
  • Assurance that liquid bulk sugar and molasses meet specifications
  • and much more

Accurate process control brings huge advantages to refineries crystalizing sugar. A supersaturation-based control strategy using process refractometers can be used to optimize crystallization, including yield, quality, and energy efficiency. Contact us for more information.


Crystallization takes place in a vacuum boiling pan. Thick juice or syrup is fed to the vacuum pans and evaporated until saturated. Seed crystals are added during a strike to grow sugar crystals. The process is continued until a specified crystal size has been reached.

Supersaturation is the driving force of crystal growth, and the speed of crystallization depends on this multivariable function of several parameters. If the supersaturation drops outside its limit, the crystals will stop growing and might even melt. If the supersaturation level rises too high, new crystals will form spontaneously. Spontaneous nucleation results in poor quality crystals of irregular shape and size (fines and conglomerates) which require reprocessing.

The efficiency of the factory, the quality of the sugar product, the capacity of the plant, and the thermal balance all depend on the operation and control of the vacuum pans to produce a high-quality massecuite.
