Anping County Boli Hardware Wiremesh Products Factory, established in 1998 with an annual export value of US$5 million to US$10 million, is proud to present our Multi-Effect Vacuum Evaporation of Salts System. Designed for 220V 50Hz 3-Phase automatic operation, this system offers a reliable and energy-efficient solution for concentrating and crystallizing saline solutions. With decades of manufacturing experience and a global footprint spanning North America, South America, Europe, Asia, and Africa, we deliver industrial-grade evaporation equipment that meets the demands of modern salt processing industries.
Our Multi-Effect Vacuum Evaporation System utilizes a series of vacuum chambers to achieve efficient separation of dissolved salts from water. By applying multiple effects, the system reuses vapor from previous stages as heating medium, significantly reducing energy consumption compared to single-effect evaporators. The 220V 50Hz 3-Phase power supply ensures stable operation in industrial environments, while the fully automatic control minimizes manual intervention, improving productivity and consistency.
Key Features & Technical Specifications
- Multi-Effect Design – Up to 3–5 effects available, achieving steam economy of 0.2–0.3 kg steam per kg water evaporated, reducing operating costs by up to 40%.
- Vacuum Operation – Low boiling point under vacuum minimizes thermal degradation of heat-sensitive materials and allows use of low-grade heat sources.
- Automatic Control – PLC-based control system with touchscreen interface, monitoring temperature, pressure, liquid level, and flow rate. Alarm functions for safe operation.
- Corrosion-Resistant Construction – Main contact parts made of SS304 or SS316L stainless steel, suitable for high-salinity and corrosive environments.
- Compact Footprint – Modular design enables easy installation and maintenance, saving floor space.
- Energy Recovery – Integrated heat exchanger preheats feed solution using discharged condensate, further improving efficiency.
- Customizable Capacity – Available in standard capacities from 500 L/h to 10,000 L/h, with custom configurations upon request.

Advantages & Customer Benefits
- Reduced Energy Costs – Multi-effect technology recycles vapor, cutting steam consumption by 50–70% compared to single-effect systems.
- High Purity Crystals – Vacuum evaporation produces uniform salt crystals with low moisture content, suitable for food-grade or industrial applications.
- Low Maintenance – Automatic self-cleaning options (CIP) and durable materials extend equipment life and reduce downtime.
- Environmental Compliance – Closed-loop system minimizes wastewater discharge; condensate can be reused.
- User-Friendly Operation – Touchscreen interface provides real-time data and historical trends, making operation simple even for non-experts.
- Flexible Integration – Can be combined with existing pre-treatment or post-treatment units (e.g., reverse osmosis, crystallizers).

Frequently Asked Questions
-
What types of salt solutions can this system handle?
It is suitable for brine, seawater, industrial wastewater containing sodium chloride, potassium chloride, magnesium sulfate, and other soluble salts. For highly corrosive solutions, we recommend stainless steel 316L. -
What is the typical payback period for energy savings?
Depending on local energy prices and capacity, the payback period is usually 1–2 years due to the multi-effect design reducing steam consumption by up to 70%. -
Can the system operate with electric heating instead of steam?
Yes, electric heating is available as an option. However, steam is more economical for large-scale operations. -
What is the maximum salt concentration achievable?
Typically, the system can concentrate brine up to saturation (e.g., 26–30% for NaCl), and with additional crystallization steps, dry salt can be obtained. -
Is the system easy to install and maintain?
Yes, the modular design allows for simple installation. Routine maintenance includes cleaning the heat exchanger and checking vacuum pumps. An automatic CIP system is optional. -
Do you provide after-sales service in my country?
Our technical team offers remote support and can arrange on-site commissioning for major projects. We also provide spare parts worldwide. -
What certifications does your factory have?
Our factory holds relevant quality management system certifications and complies with international standards. Please contact us for specific documentation. -
Can I get a sample test before purchasing?
Yes, we can perform a pilot test in our lab using your solution sample. Results are provided within 2–3 weeks.
