ABSTRACT:
Pullulan is precipitated from an aqueous solution by mixing with a hydrophilic organic solvent incapable of dissolving pullulan. Solid pullulan is then separated from the liquid component of the dispersion by feeding the dispersion into a V-type disk press having a pair of discoid screens arranged so that the distance between them decreases as they are rotated. The pullulan dispersion is pressed by the discoid screens, recovering the liquid component through the screens. The resulting low-liquid-content pullulan continues to rotate together with the screens to an outlet, where it is discharged from the press.
