Abstract
Solid saccharides are produced from an aqueous saccharide solution in a process, where the aqueous saccharide solution is admixed with a carrier liquid in which the saccharides are insoluble and that has a boiling point higher than that of water to obtain an aqueous admixture, and where the aqueous admixture is subjected to an evaporation step. The heat for the evaporation is at least partially supplied by a heated surface area to yield a vapor fraction including water and a residue fraction including solid saccharides and carrier liquid.
Claims18
A process for the production of solid saccharides from an aqueous saccharides solution comprising:
- admixing the aqueous saccharides solution with a carrier liquid, in which the saccharides are insoluble and the carrier liquid, which has not been heated, has a boiling point higher than that of water, to obtain an aqueous admixture, and
- subjecting the aqueous admixture to an evaporation step in an evaporator, wherein the heat for the evaporation is at least partially supplied by a heated surface area of the evaporator, to yield a vapor fraction comprising water, and a residue fraction comprising solid saccharides and carrier liquid,
- wherein the evaporation step is conducted in one or more equipments selected from the group consisting a stirrer evaporator, a rising film evaporator, a circulation evaporator, a forced circulation evaporator, a falling film evaporator, a rising-falling film evaporator, a spiral tube evaporator, a thin film evaporator and a short path distillation unit, and
- wherein the residue fraction is separated into a solids stream comprising the solid saccharides and a liquid stream comprising the carrier liquid.
