Hydrosol Filtration and Low-Temperature Concentration Equipment

Membrane Filtration and Membrane Concentration Equipment for Hydrosols—Opening a New Era of Purity in Natural Plant Extraction

In the field of natural plant extraction, hydrosols have become a popular raw material in the cosmetics, health products, food, and pharmaceutical industries due to their rich content of plant active ingredients, natural aroma, and mild properties. However, traditional hydrosol production processes often face issues such as loss of active ingredients, residual impurities, high energy consumption, and low efficiency, which directly affect product quality and market competitiveness. As an advanced equipment manufacturer specializing in the research and development of membrane separation technology, we have introduced a membrane filtration and membrane concentration equipment solution for hydrosols to address industry pain points. Our innovative technology empowers natural plant extraction, helping enterprises achieve efficient, energy-saving, and high-quality production.

I. Pain Points in Hydrosol Production: Limitations of Traditional Processes
Traditional hydrosol production processes mostly use distillation combined with simple filtration, which presents the following problems:
1. Loss of active ingredients: High-temperature distillation and rough filtration can easily damage heat-sensitive components, reducing efficacy;
2. High residual impurities: Macromolecular colloids, suspended solids, and microorganisms are difficult to remove completely, affecting product stability and safety;
3. Low concentration efficiency: Evaporation concentration consumes high energy, takes a long time, and incurs significant cost pressures;
4. Poor batch stability: Process parameters are difficult to control precisely, leading to significant fluctuations in product quality.

How can we achieve efficient separation, active ingredient retention, and safe purification of hydrosols while reducing energy consumption and costs? The answer lies in membrane separation technology.

II. Empowering Hydrosol Production with Membrane Technology: Precision Separation and Quality Enhancement
Our hydrosol membrane filtration and membrane concentration equipment adopts a multi-stage membrane combination process, including ceramic membranes, ultrafiltration membranes, nanofiltration membranes, and reverse osmosis membranes. This allows for precise control at different production stages, comprehensively optimizing hydrosol quality and production efficiency.

1. Membrane Filtration Process: Efficient Impurity Removal and Active Ingredient Retention
- Pretreatment stage: Uses microfiltration membranes (MF) or tubular membranes to quickly intercept plant residues and suspended particles, reducing the load on subsequent processes;
- Fine filtration stage: Utilizes ultrafiltration membranes (UF) (molecular weight cut-off 1kDa-100kDa) to remove macromolecular colloids, proteins, and some microorganisms while retaining small-molecule active substances;
- Sterilization and purification stage: Leverages the high-temperature and corrosion-resistant properties of ceramic membranes to achieve efficient sterilization in high-temperature environments, avoiding the need for chemical preservatives and ensuring natural product safety.

2. Membrane Concentration Process: Low-Temperature Efficiency and Energy Savings
- Nanofiltration membranes (NF): Selectively retain target active ingredients while removing some water and inorganic salts, achieving low-temperature pre-concentration and avoiding loss of heat-sensitive components;
- Reverse osmosis membranes (RO): Further concentrate hydrosols at room temperature, with a dehydration rate of over 90%, significantly reducing subsequent drying energy consumption;
- Hollow fiber membranes: Designed for high-viscosity materials with cross-flow filtration, offering strong anti-fouling properties and stable operational flux.

Technical Advantages:
✅ Active ingredient retention rate >95%: Low-temperature filtration and concentration processes maximize protection of heat-sensitive components;
✅ Impurity removal rate >99.9%: Ensures product clarity and transparency, with microbial indicators meeting international standards;
✅ Energy consumption reduced by 40%-60%: Compared to traditional evaporation processes, membrane concentration significantly lowers overall energy consumption;
✅ Modular design: Supports flexible capacity expansion, adaptable to small-scale, pilot-scale, and large-scale production needs.

III. Success Stories: Membrane Technology Helps Enterprises Break Through Bottlenecks
Case 1: A Well-Known Cosmetics Enterprise
The original process used centrifugation + evaporation concentration, resulting in issues such as loss of rose hydrosol aroma and yellowing of color. After adopting our ceramic membrane ultrafiltration + reverse osmosis membrane concentration system:
- Retention rate of active ingredients (e.g., phenylethanol, citronellol) increased to 98%;
- Product light transmittance >99%, with a pure aroma;
- Concentration energy consumption reduced by 50%, saving over 800,000 RMB annually.

Case 2: Organic Farm Lavender Hydrosol Production
The customer required an entirely additive-free process while retaining natural efficacy. We customized a tubular membrane pretreatment + nanofiltration membrane graded concentration solution:
