Crystallization takes place in a vacuum boiling pan. Thich 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.
