Anthocyanin/Natural Pigment Extraction Membrane Separation Equipment - Plant Pigment Production Line - XH Ultrafiltration + Nanofiltration

Xihe Fluid Technology | Ultrafiltration + Nanofiltration System: The Innovative Solution for Anthocyanin Purification and Concentration 

       In industries such as food, health products, and cosmetics, anthocyanin has become a market favorite due to its exceptional antioxidant properties and natural coloring ability. However, traditional purification processes face challenges such as low efficiency, high energy consumption, and susceptibility to degradation of active components. Leveraging over a decade of expertise in membrane separation technology, Xihe Fluid Technology introduces the "Ultrafiltration + Nanofiltration" dual-membrane synergistic system, offering a groundbreaking solution for large-scale anthocyanin production. 

I. Dual-Membrane Synergy: Breaking Through Traditional Process Bottlenecks 

        Xihe's system employs a combined process of Ultrafiltration (UF) + Nanofiltration (NF), achieving molecular-level precision separation of anthocyanin. 

        - Ultrafiltration membrane (molecular weight cutoff: 10-100 kDa): Efficiently retains macromolecular impurities such as proteins and polysaccharides while preserving anthocyanin's active components. Compared to traditional solvent extraction methods, impurity removal efficiency increases by over 40%, and the extract's light transmittance reaches 98%. 

        - Nanofiltration membrane (molecular weight cutoff: 100-500 Da): Selectively retains anthocyanin molecules while removing impurities like inorganic salts and small-molecule pigments. Experimental data show that after dual-membrane treatment, anthocyanin purity increases from 52% to 79%, with energy consumption reduced by 35% compared to traditional column chromatography. 

        - Low-temperature operation: The entire process operates at room temperature, preventing anthocyanin degradation caused by high temperatures and preserving its antioxidant activity (ORAC value increases by 20%). 

II. Three Core Advantages: Redefining Production Standards 

1. High Efficiency and Energy Savings

        - Utilizes cross-flow filtration technology to reduce membrane fouling, extending stable flux duration by 50% and increasing cleaning cycles from 8 hours in traditional processes to 24 hours. 

        - Energy consumption is only 8%-10% of that of vacuum thermal concentration. For example, in a project producing 100 tons of anthocyanin annually, electricity costs are reduced by over 300,000 RMB per year. 

2. Quality Upgrade

        - Precise control of membrane pore size avoids organic solvent residues common in traditional resin adsorption methods, ensuring products comply with international standards such as EU EFSA and US FDA. 

        - Preserves anthocyanin's natural conformation, improving color stability in food applications by 3 times and extending shelf life to 18 months. 

3. Smart Integration

        - Modular design supports flexible capacity expansion (from 50 L/h to 10 m³/h), equipped with a PLC automatic control system for one-click startup and remote monitoring. 

        - Constructed with 316L stainless steel, compliant with GMP certification, and seamlessly integrable with downstream processes like spray drying and freeze drying. 

III. Full-Scenario Adaptability: Empowering Innovation Across Industries 

        - Food and Beverage: Used for clarification and concentration of products like blueberry juice and purple sweet potato beverages, replacing traditional diatomite filtration and reducing turbidity to below 0.1 NTU. 

        - Health Products: Extracts high-purity anthocyanin (≥95%) for use in capsules, oral liquids, and other formulations, increasing bioavailability by 3 times. 

        - Cosmetics: Separates anthocyanin monomers (e.g., cyanidin-3-O-glucoside) for use in high-end products like anti-aging serums and sunscreens. 

IV. Dual Assurance of Technology and Service 

        - One-stop service: Provides comprehensive support from raw material analysis and small-scale validation to full-line delivery, having successfully served over 20 domestic anthocyanin production enterprises. 

       - Environmental commitment: Achieves a wastewater reuse rate of 90%, reducing wastewater discharge per ton of product by 60% compared to traditional processes, helping enterprises meet "dual carbon" goals.
