Membrane Separation Technology for Plant Extracts

Product Overview

The plant extraction membrane separation technology is an efficient and environmentally friendly solution for isolating active plant components. By integrating ceramic membranes, Flow-Cel membrane filtration, ultrafiltration (UF), nanofiltration (NF), continuous moving bed (CMB) separation, and wastewater recovery, the system achieves clarified and transparent extracts, enriched active compounds, and reduced solvent and water consumption. This technology enhances crystallization yield and production efficiency, promoting green manufacturing and resource recycling.

Working Principle

• Membrane Filtration: Ceramic and Flow-Cel membranes replace traditional plate-and-frame filtration to remove suspended solids, pigments, and impurities, improving filtrate clarity and quality.

• Ultrafiltration & Nanofiltration: UF removes proteins and pigments to enhance extract quality; NF concentrates the extract, shortens evaporation time, increases crystallization yield, and reduces evaporation loss.

• Continuous Moving Bed (CMB) Technology: Replaces fixed-bed separation, significantly reducing resin consumption, lowering unit costs, and improving overall resource efficiency.

• Waste Liquid Recovery: Membrane separation enables recovery of mother liquor, wastewater, and process water, maximizing resource reuse and minimizing wastewater discharge.

Key Features

• High Clarification Efficiency: Effectively removes impurities, ensuring transparent and high-quality extracts.
• Environmentally Friendly & Energy Saving: Reduces dependence on traditional solvents, lowers energy consumption, and minimizes environmental impact.


• Resource Recycling: Enables mother liquor and wastewater recovery, supporting near-zero discharge and sustainable production.
• Cost-Effective: Continuous moving bed technology reduces resin and regenerant consumption, lowering production costs.

Applications

• Food Industry: Production of natural plant extracts, such as stevia, enhancing extract quality and yield.
• Cosmetics Industry: Extraction of plant essences for high-quality cosmetic formulations.

• Pharmaceutical Industry: Isolation of active plant components for pharmaceuticals and health products.
• Environmental Protection: Recovery and treatment of mother liquor and wastewater to support green production and sustainability.
