Product Overview
The Pectin Refining and Concentration Equipment is a professional integrated solution independently developed by ZLN Technology Co., Ltd.—a National High-tech Enterprise with over 20 years of membrane separation and food processing expertise. Tailored for the industrial production of pectin (extracted from citrus peels, apple pomace, etc.), this equipment addresses the core pain points of traditional pectin processing: low purity due to incomplete impurity removal, reduced gel strength from thermal degradation, and high energy consumption from conventional concentration methods.
Integrating advanced membrane separation technologies (ultrafiltration, nanofiltration) with precision centrifugation and low-temperature concentration systems, the equipment covers the entire production chain from crude pectin extract pretreatment, refining, and desalination to concentration and finished product processing. It realizes molecular-level precision separation and gentle concentration of pectin, ensuring the final product has high purity (≥90%), excellent gel performance, and retained functional activity. Compliant with GMP, FDA, and other international standards, the equipment has been widely applied in food additive manufacturers, pharmaceutical raw material suppliers, and functional food producers, providing reliable technical support for large-scale, high-quality pectin production.
Core Advantages
1. High Purity & Superior Gel Performance
Adopts multi-stage precision refining (centrifugation + ultrafiltration + nanofiltration), effectively removing small-molecule sugars, proteins, mineral salts, pigments, and residual fruit peel residues. The impurity removal rate reaches ≥95%, and the finished pectin purity is ≥90%, with gel strength and stability significantly higher than traditional alcohol precipitation processes.
2. High Retention of Active Ingredients
Operates at room temperature (25–35℃) throughout the refining and concentration process, avoiding thermal degradation of pectin macromolecules. The gel activity retention rate reaches ≥98%, ensuring the finished product maintains excellent thickening, stabilizing, and gelling properties required for food and pharmaceutical applications.
3. Energy-Saving & Environmental Protection
Membrane concentration technology consumes only 30–40% of the energy of traditional thermal concentration, greatly reducing production costs. The pure physical separation process requires no organic solvents (e.g., ethanol), avoiding environmental pollution and solvent residue risks, meeting clean production requirements.
4. Targeted Design for Pectin Characteristics
Customizes process parameters and membrane configurations based on pectin's high colloid content and viscosity: uses ultrafiltration membranes (10–50 kDa) to intercept macromolecular pectin while removing small-molecule impurities; optimizes cross-flow filtration to prevent membrane fouling; supports adjustable desalination rate (≥90%) for high-ash raw materials.
5. Intelligent & Stable Operation
Equipped with a PLC automatic control system, real-time monitoring of key parameters such as filtration pressure, concentration temperature, and solid content. Features an online CIP cleaning system to reduce membrane fouling and extend the service life of core components to 2–3 years, ensuring consistent product quality across batches.
Main Features
1. Full-Chain Integration
Covers all links of pectin processing—crude extract pretreatment, precision refining, desalination, low-temperature concentration, and post-treatment—forming a closed-loop production system. Reduces floor space by 30% compared to split equipment and simplifies workflows.
2. Advanced Membrane Application
Provides one-stop services from on-site raw material testing, process design, equipment manufacturing, and installation to commissioning, operator training, and after-sales maintenance, adapting to diverse production needs.
3. Flexible Concentration Control
Supports adjusting the concentration endpoint (20–30% solid content) according to production needs, avoiding gelatinization caused by excessive concentration and reducing subsequent drying load.
4. Compliance & Safety Assurance
All parts in contact with materials use food-grade 304/316L stainless steel, PVDF/ceramic membranes, and FDA-compliant components. The process meets food safety and environmental protection standards, ensuring product safety and compliance.
5. Turnkey Service Capability
Provides one-stop services from on-site raw material testing, process design, equipment manufacturing, and installation to commissioning, operator training, and after-sales maintenance, adapting to diverse production needs.
