Glucosamine hydrochloride, as a health-care pharmaceutical, plays an excellent role in protecting joints. A mature production process for glucosamine hydrochloride is fermentation. In the fermentation process, the fermentation broth has a complex composition, containing a large amount of culture medium, mycelia, miscellaneous proteins, pigments and other impurities. To separate and purify glucosamine hydrochloride, various processes need to be combined.
Chengdu HeCheng Filtration Technology Co., Ltd. has developed a set of membrane separation processes for glucosamine hydrochloride impurity removal and concentration based on the material properties of glucosamine hydrochloride and the application characteristics of membrane separation technology, which improves product quality, reduces energy consumption, and saves production costs.
Brief Introduction to Membrane-based Impurity Removal and Concentration Process for Glucosamine Hydrochloride Fermentation broth → Ceramic membrane separation system → Low-pressure membrane concentration system → Medium-pressure membrane concentration system → MVR/multi-effect thermal concentration → Subsequent processes
The concentrated solution after ceramic membrane separation is subjected to plate-and-frame filtration. The filter cake, consisting of bacterial cells and culture medium residues, can be used as feed.
The low-pressure membrane concentration system increases the concentration of glucosamine hydrochloride to 50g/L.
The medium-pressure membrane concentration system increases the concentration of glucosamine hydrochloride to more than 100g/L.
The permeate from the two-stage concentration is reused in the previous extraction process, with the glucosamine content in the permeate being less than 0.2g/L.
MVR has much lower energy consumption than traditional thermal concentration. It uses a steam compressor to compress steam, improving steam utilization and saving a large amount of steam.
Technical Features of Membrane Separation System Equipment
Advanced nanoscale membrane separation elements enable selective separation and concentration at the molecular level.
Unique cross-flow operation process solves the problem of easy clogging of filtration and separation elements.
Reduces solvent consumption, saves energy, reduces emissions, and complies with national environmental protection policies.
