Edible sugar manufacturing is a delicate process that requires process control and instant, accurate Brix (massecuite solids content) measurement of raw and in-process liquids for best product quantity and quality, measured with for example mean aperture (MA) and coefficient of variation (CV). Only high-quality liquid and crystal sugars are acceptable. In crystal sugar manufacturing, the absolute goal is to produce the maximum amount of even quality crystals, avoiding fines and conglomerates.
Sugar production involves two distinct operations: processing sugar cane or sugar beets into raw sugar and processing the raw sugar into refined sugar.
As sugar refining is a highly energy-intensive process where raw juice is subjected to multiple processing steps to remove impurities, the right process control tools help to maximize yield and minimize the cost of production. Overall, the sugar industry is a large water consumer as each production step requires water. The water and energy consumption during manufacturing can be significantly reduced, contributing to mill's or refinery's sustainability, by using modern technology equipment, such as Vaisala Polaris™ process refractometer.
Sugar crystallization is often the main production process, and mass-producing quality and constant sugar at a competitive price require robust measurement devices that are not affected by varying process conditions from the liquid phase to massecuite nor by increasing crystal content during a strike.
Supersaturation is the driving force of crystal growth, and the speed of crystallization depends on this multivariable function of several parameters. Supersaturation has an optimal range, where sugar crystals grow evenly and widely. Outside the range, the crystals will stop growing and might even melt or start to form new crystals spontaneously creating fines and conglomerates requiring reprocessing. The Zutora SeedMaster-4 is a unique device specifically created for sugar crystallization, providing the parameters necessary for sugar crystallization.
