Crystalline Fructose



Mix the F55 syrup with the reflux hydrol from centrifuge separation and hot process water to adjust the concentration to about 60%


The concentrate adjusted syrup is sent to chromatography separation (SSMB) system. The fructose content of the extract part is not less than 99%. The raffinate part reflux to existing F55 production line

3.F99 syrup concentration

Part of the water will be removed from the syrup and finally the concentration of the discharge syrup from evaporation system DS75~80%

4.Vacuum evaporating pre-crystallizing

F99 high fructose enters vacuum evaporating crystallizing tank, the soluble fructose volume keeps decreasing as the water is being evaporated. The insoluble part will be crystallized from the syrup, the crystallizing ratio reaches a certain value when the evaporating is finished

5.Cooling crystallizing

The product from evaporation crystallizer is put into the horizontal crystallizer, then slowly cooled down to a certain temperature, the fructose crystals will grow to bigger particles, and final crystallizing rate could reach a certain figure

6.Centrifuge separating

Crystallized massecuite enters separator, the high purity crystals will be kept in the basket of the centrifuge separator, the soluble fructose and small amount of miscellaneous will be discharged from separator and used as mother liquor which will reflux back to blending tank


The separated crystalline fructose still has 1~2% moisture, which should be decreased below 0.1% for product standard and longtime storage, vibrating fluid bed drying and cooling machine is used for drying the crystalline fructose.
