Abstract

The invention relates to a continuous method for obtaining a crystalline monosaccharide, comprising: continuous crystallization of the monosaccharide in a main crystallizer (), wherein crystallization by evaporation and/or crystallization by cooling is carried out continuously on a crystal suspension in the main crystallizer in order to allow crystals of the monosaccharide to grow in the crystal suspension; separation of crystals of the monosaccharide out of the crystal suspension to obtain crystalline monosaccharide; continuous formation of a mass of crystallization magma for the main crystallizer () in a cascade, wherein the cascade comprises at least one first stage () and a final stage () connected in series and each stage comprises at least one pre-crystallizer (A,A), wherein, in the at least one pre-crystallizer (A) of the first stage (), a solution is seeded with monosaccharide by means of monosaccharide seed crystals in order to obtain a pre-crystallization magma, and a mass of crystallization magma for the downstream stage () is formed from the pre-crystallization magma by means of crystallization by cooling and/or crystallization by evaporation, and wherein a solution containing monosaccharide and a mass of crystallization magma from the upstream stage is supplied to the at least one pre-crystallizer (A,B,C) of the final stage () to obtain a pre-crystallization magma, and in the at least one pre-crystallizer (A,B,C) of the final stage () a mass of crystallization magma for the main crystallizer () is formed from the pre-crystallisation magma by means of crystallization by cooling and/or crystallization by evaporation; the continuous supply of a solution containing the monosaccharide and a mass of crystallization magma from the at least one pre-crystallizer (A,B,C) of the final stage () of the cascade to the main crystallizer () to provide the crystal suspension.
