Product Overview
The Dairy Whole Production Line Membrane Sterilization and Concentration Equipment, developed by Zhengzhou Chlory Technology Co., Ltd.—a National High-tech Enterprise with over 20 years of membrane separation expertise—is a specialized integrated solution tailored for the dairy processing industry. Targeting core industry pain points such as thermal nutrient loss, high energy consumption, and flavor damage in traditional dairy processing (pasteurization, vacuum evaporation), this system adopts advanced membrane separation technologies (Microfiltration - MF, Ultrafiltration - UF, Nanofiltration - NF).
It realizes efficient sterilization, purification, and concentration of dairy products (raw milk, whey, yogurt base, etc.) through molecular-level sieving and low-temperature physical separation. While effectively removing bacteria, somatic cells, macromolecular impurities, and redundant salts, it maximizes the retention of heat-sensitive nutrients (whey protein, immunoglobulin, vitamins) and natural flavors. Fully compliant with international standards (GMP, FDA), the system has been widely applied in milk powder, whey protein powder, condensed milk, and functional dairy production, providing reliable support for high-quality, low-consumption, and standardized production in the dairy industry.
Core Advantages
1. Low-Temperature Operation & Nutrient Preservation
Operates at room temperature (25-40℃) without phase change, avoiding thermal denaturation of heat-sensitive components such as whey protein and vitamins. The retention rate of active nutrients reaches ≥95%, ensuring the natural nutritional value and flavor of dairy products.
2. High-Efficiency Sterilization & Stable Quality
MF/UF membrane technology achieves ≥99.99% removal of bacteria, yeast, mold, and somatic cells in dairy products, replacing traditional pasteurization. It solves the problem of cold turbidity caused by protein-polyphenol complexes, extending the shelf life of dairy products to 6-12 months while maintaining consistent product quality.
3. Energy Saving & Cost Reduction
Energy consumption is only 30-40% of traditional vacuum evaporation concentration processes, significantly reducing water and electricity costs. The pure physical separation process requires no chemical agents or filter aids, avoiding secondary pollution and reducing operating costs by 30-50%.
4. Dual-Function Integration & High Adaptability
Integrates sterilization, purification, concentration, and desalination functions. Supports customized configuration for different dairy products (raw milk, whey, probiotic drinks) and production scales (pilot to industrial), adapting to both new production line construction and old line upgrades.
5. Compliant & Safe Production
All parts in contact with materials are made of food-grade 304/316L stainless steel and PVDF/ceramic membranes, complying with strict food safety standards. The process has no chemical residues, ensuring the safety and hygiene of dairy products and meeting regulatory requirements.
Main Features
1. Modular Design & Flexible Configuration
Supports customized combination of MF (sterilization), UF (protein concentration), and NF (lactose concentration/desalination) membrane modules based on processing requirements. Processing capacity ranges from 50-100 Kg/h (pilot scale) to 5000-8000 Kg/h (industrial scale), adapting to diverse production needs.
2. Intelligent Automatic Control
Equipped with a PLC control system and touchscreen interface, enabling real-time monitoring and automatic adjustment of key parameters (pressure, flow rate, temperature, turbidity, protein concentration). Supports unattended operation, automatic backwashing, and abnormal alarm functions, reducing manual intervention and human error.
3. Integrated CIP Cleaning System
Built-in online Clean-in-Place (CIP) system with acid, alkali, and enzyme cleaning programs. Automatically cleans membrane surfaces and pipelines without disassembly, efficiently removing protein adsorption, colloidal deposition, and scaling, extending membrane service life to 2-3 years.
4. Durable & Corrosion-Resistant Materials
Adopts food-grade membrane materials (PVDF, ceramic, TFC) and 304/316L stainless steel for wetted parts, featuring excellent chemical resistance (pH 2-12) and corrosion resistance. It adapts to harsh dairy processing conditions (high viscosity, high protein content) and avoids material leaching.
5. Turnkey Project Capability
Provides one-stop services from technical con-sultation, dairy product property analysis, pilot-scale verification, and equipment manufacturing to on-site installation, commissioning, and opera-tor training. Seamlessly integrates with existing dairy production lines (centrifuges, spray dryers) to form a complete processing chain.
