The disclosure relates to a method for separation and purification of N-acetyl-glucosamine, and belongs to the technical field of biological engineering. In the disclosure, a raw material solution containing N-acetyl-glucosamine is obtained by microbial fermentation or by hydrolyzing the chitin. The raw material solution is subjected to flocculation pretreatment, and continuous centrifugation or pressure filtration is performed to remove suspended solids such as microorganisms, proteins and polysaccharides to obtain clear liquid. Double-stage ion exchange chromatography is performed to remove impurities such as charged organic molecules and inorganic salts. Membrane concentration is performed to efficiently remove water to improve the concentration of the target product. Spray drying or further evaporation concentration and crystallization are performed. Finally drying is performed to obtain an N-acetyl-glucosamine crystal of which the purity is more than 99%.

A purification system for separating a molecule of interest from a solution is provided and generally includes a plurality of resin processing sections, wherein each of the resin processing sections is controllably separated from each other via a configurable gate valve, wherein the configurable gate valve is configured to introduce or evacuate a fluid/resin into/out of a proximately located processing section, a plurality of inlets configured to introduce fluid and/or resin into one or more of the plurality of resin processing sections.
