Nanofiltration Membrane for Herbal Extract Decolorization
Crude herbal extract often presents dark color caused by macromolecular pigments, tannin polymers and humus‑like substances. Conventional decolorization relies heavily on activated carbon adsorption, which leads to effective ingredient loss, disposable carbon waste and complicated post‑treatment. Nanofiltration membrane realizes physical decolorization by molecular weight cut‑off difference. It intercepts most high‑molecular‑weight pigments while retaining majority of target active components. This article discusses the mechanism of nanofiltration decolorization, compares with activated carbon process, analyzes influencing factors such as temperature, pH and transmembrane pressure, and states application value for herbal and plant extract factories.
Ceramic Membrane for Syrup Purification in Sugar Industry
Traditional fruit wine clarification commonly adopts bentonite adsorption and diatomite filtration. These conventional methods will cause loss of aroma substances, introduce exogenous additives and generate plenty of filter waste. Cross‑flow membrane filtration becomes a promising physical clarification solution for fruit wine production. Without adding flocculants, the cross‑flow membrane system removes suspended pulp residues, colloids and microbial particles under moderate operating pressure. It stabilizes fruit wine quality and shortens the aging cycle. This article describes working principle of cross‑flow membrane, compares it with traditional clarification processes, analyzes key operating parameters and summarizes practical benefits for fruit wine manufacturers.
