An apparatus for continuously crystallizing sugar, both by developing crystals from sugar solutions and by exhausting solutions of mother liquor from a massecuite, or cooked mass, by means of evaporation of said solutions over seed crystals, said apparatus comprising a hollow horizontal cylinder which in its upper portion and over its entire length has connected to itself along a slot a rectangular cover which thus forms a single body; means for heating the exterior of the hollow cylindrical body; means for producing a helicoidal movement in the mass being processed; means for connecting the hollow cylindrical body by means of the rectangular cover to a source of low pressure; means for feeding into the front end a controlled quantity of a solution of sugar or of a massecuite; means for feeding controlled replacement quantities of sucrose solution or of mother liquors to replace the water evaporated and the material crystallized, and to increase the volume of the mass being processed, and means for controlled discharge included in the rear end of the hollow cylindrical body.
