text: Considering several other factors related to the processes of the prior art, it becomes evident that the crystallization of fructose from aqueous or aqueous alcoholic media is highly complex inasmuch as it involves many process variables and requires stringent conditions for the operation of the system, such as: high solids concentration in the fructose-rich syrup used as the feed for the crystallizer (normally, higher than 90% by weight dry solids); high fructose purity of this crystallizer feed syrup (higher than 90% (dsb) fructose, preferably between 93 and 96% (dsb)); very high solubility of fructose in water; extremely high effective viscosities of the aqueous massecuite; narrow operating ranges for the pH of the solution; characteristics of the alcohol addition (temperature and rate of addition, and fructose-to-alcohol ratio); granulometric characteristics of the seed; characteristics of the seed addition (temperature and rate of addition, and proportion between the mass of fructose seed crystals and the mass of fructose in the syrup); accurate control of temperature during the additions of the alcohol and the seed, so as to eliminate or minimize spontaneous nucleation; and establishment of a precise degree of supersaturation of the fructose solution through an accurate control of its cooling.
