AQUEOUS-ALCOHOL FRUCTOSE CRYSTALLIZATION

摘要

An aqueous-alcohol mixture including fructose is crystallized by the inventive process. The first process step is to feed a hot, fructose, feed stream into an evaporator which immediately cools the feed stream to start a crystallization process. Then alcohol is mixed into the crystallizing feed stream or magma and the resulting mixture is linearly cooled over an extended period of time. Thereafter, the crystallized material is collected, filtered, and dried. The resulting crystals are then sorted by size. There is no seeding or feeding back of product in order to start the crystallization process.
