This work presents the improvement of vacuum pressure and total evaporation time based on the metastable zone width ( and crystallization kinetics. An approach of fractional feeding was used in a cane sugar batch crystallizer at pilot-scale plant, operating condition imposed in the cane sugar industrial crystallization. The  was used as a strategy to limit the concentration within the saturation and metastable curves. It was coupled with a detailed analysis for primary nucleation and crystal growth, based on mechanistic kinetic models. The more efficient strategy for the fractional feeding increase  to 1089.51  avoiding losses of  (4,700.98 gr) at final process time of 90 min
