  • Process for continuously producing sugar
    Patent number: 4050953
    Abstract: In a continuous sugar evaporator-crystallizer having a plurality of evaporating-crystallizing vessels as stages, each evaporating-crystallizing stages being communicated one to another in series and being provided with a means for feeding an aqueous sugar solution, a heating means and a means for withdrawing generated steam, by feeding an aqueous sugar solution to each evaporating-crystallizing stage, heating the aqueous sugar solution in each evaporating-crystallizing stage, thereby evaporating water off the aqueous sugar solution and crystallizing sugar crystals, and withdrawing the generated steam from each of the stages, while feeding seed sugar crystals to the first evaporating-crystallizing stage and withdrawing the resulting sugar crystal slurry from the last evaporating-crystallizing stage, sugar crystals of high quality is obtained in the slurry with an effective suppression of occurrence of conglomerated sugar grains by providing sugar crystal distances of 0.26 to 0.
