Process Brief:

In the production of fermented functional sugars, ceramic membranes and organic membranes are combined into an efficient integrated process. The fermentation broth first enters the ceramic membrane system, where its high-precision sieving and fouling-resistant properties effectively retain cells, macromolecular proteins, and suspended particles, achieving clarification and sterilization of the feed liquid. The clarified permeate then proceeds to the organic membrane system for further purification and concentration: ultrafiltration removes residual macromolecules, while nanofiltration removes small-molecule impurities and concentrates the functional sugars at ambient temperature.

Technical Advantages:

Ceramic membranes deliver clear filtrate through high-precision crossflow filtration; subsequent organic membranes achieve desalting and dehydration at ambient temperature via nanofiltration, avoiding thermal degradation of functional sugars. The entire process replaces traditional evaporation, significantly reducing energy consumption. Ceramic membranes offer strong fouling resistance and stable flux, and with PLC automation control, membrane life is extended and maintenance costs are reduced.
