ABSTRACT:
A method for continuously precipitating a polysaccharide dissolved in an aqueous solution wherein a non-solvent for the polysaccharide is admixed with the aqueous solution to cause the polysaccharide to precipitate from the solution. The method includes the step of simultaneously feeding the aqueous solution containing the dissolved polysaccharide and the non-solvent through respective constant flow rate-pumps to produce non-pulsating metered first and second streams which are unaffected by pressure changes in the aqueous solution or the non-solvent fed to the respective pumps. The metered streams are simultaneously introduced from the respective pumps into a rotary turbine to mix the solution and the non-solvent and precipitate the polysaccharide. The precipitated polysaccharide is cut with an interlocking cutter which comprises a fixed cutter and a rotary cutter, and a suspension of finely cut polysaccharide particles is continuously withdrawn.
