Expert in Protease Membrane Separation, Purification, and Concentration Equipment, Empowering Efficient Upgrades in Biomanufacturing

With the rapid development of the biopharmaceutical, food processing, and detergent industries, protease, as a core enzyme preparation, has its purity and activity directly determining the efficacy of end products. However, traditional production processes face pain points such as residual impurities, enzyme activity loss, and high energy consumption during concentration, severely restricting companies' efforts to reduce costs, improve efficiency, and achieve quality breakthroughs. Xihe Fluid Technology, with its independently developed membrane separation, purification, and concentration equipment, provides protease producers with a full-process solution featuring high-precision separation, low-temperature activity retention, and energy-saving environmental protection, helping customers achieve industrial upgrades characterized by "high purity, high activity, and low cost"!

I. Pain Points in Protease Production: Three Major Constraints of Traditional Processes
1. Severe Activity Loss: High-temperature evaporation and salting-out precipitation cause denaturation and inactivation of enzyme proteins, with enzyme activity retention rates ≤70%;
2. Incomplete Impurity Removal: Centrifugation and chromatography struggle to separate impurities with similar molecular weights, resulting in insufficient product purity;
3. High Comprehensive Costs: Multi-stage purification steps are complex, solvent consumption is high, and production costs per ton of enzyme exceed ￥10,000.

Xihe Fluid's membrane separation technology, through physical screening and low-temperature concentration, offers three key features—"precise retention, gentle operation, and high efficiency and energy savings"—making it an innovative choice for protease production!

II. Xihe Fluid's Technical Advantages: How to Solve Enzyme Production Challenges?
1. Four-Stage Membrane Process Chain for Full-Process Purification and Efficiency
- Microfiltration (MF): Removes cells and suspended particles from fermentation broth (pore size 0.1-1μm), with light transmittance ≥95%;
- Ultrafiltration (UF): Precisely retains target proteases (10-100kDa), removes small molecule impurities and foreign proteins, increasing purity to ≥90%;
- Nanofiltration (NF): Concentrates enzyme solution at low temperatures, increasing solid content to 20%-30%, with enzyme activity retention ≥95%;
- Reverse Osmosis (RO): Deep dehydration reduces subsequent drying energy consumption by 50%, compatible with spray drying or freeze-drying processes.

2. Low-Temperature Activity Retention, Enzyme Activity Retention ≥95%
- Entire process temperature ≤40°C, avoiding damage to enzyme protein spatial structure and ensuring catalytic activity;
- Pure physical separation process, eliminating chemical residues such as ammonium sulfate, compliant with FDA and GMP certification standards.

3. Energy Saving and Consumption Reduction, Comprehensive Costs Reduced by 50%
- Energy consumption reduced by 60%-70% compared to traditional evaporation processes, with processing costs per ton of enzyme ≤￥5,000;
- Wastewater reuse rate ≥80%, COD reduction ≥90%, supporting green factory certification.

III. Application Scenarios: How Membrane Technology Empowers Protease Production
1. Fermentation Broth Pretreatment
- Pain Point: Residual cells interfere with subsequent purification, and centrifugation efficiency is low;
- Solution: Ceramic microfiltration rapidly removes cells, increasing processing capacity by 3 times, with enzyme recovery rate ≥99%.

2. Enzyme Solution Refinement and Purification

- Pain Point: Impurities and target enzymes have similar molecular weights, making chromatography costly;

- Solution: Ultrafiltration membranes precisely retain target enzymes, with impurity removal rate ≥90%, achieving purity above 90%.

3. High-Concentration Enzyme Solution Preparation
- Pain Point: Traditional evaporation causes enzyme activity decline and high drying energy consumption;
- Solution: Nanofiltration low-temperature concentration increases enzyme solution solid content to 25%, reducing drying time by 40%.

IV. Xihe Fluid vs. Traditional Processes: Data Demonstrates the Technological Gap
