Welcome to Anping County Boli Hardware Wiremesh Products Factory – a trusted manufacturer with over 25 years of experience since 1998. Our Automatic Electric Multi-Effect Vacuum Evaporation System is designed for high-efficiency PDV salt production, featuring 304 stainless steel construction and advanced PLC control. This system combines superior corrosion resistance, precise automation, and energy-saving multi-effect technology to deliver consistent salt quality and reduced operational costs. Whether you are a small-scale producer or a large industrial plant, this evaporation system offers a reliable solution for your salt concentration needs.
Key Features & Technical Specifications
- 304 Stainless Steel Construction – Ensures long service life, excellent corrosion resistance against brine and salt solutions, and easy cleaning.
- Multi-Effect Evaporation Design – Utilizes multiple evaporation stages to recover heat energy, reducing steam consumption by up to 40% compared to single-effect systems.
- PLC Automatic Control – Touchscreen interface with one-touch operation, real-time monitoring of temperature, pressure, liquid level, and flow rate. Minimal manual intervention required.
- High Efficiency for PDV Salt Production – Specifically optimized for producing pure dried vacuum salt (PDV) with consistent crystal size and low moisture content.
- Energy-Saving – Integrated heat recovery system and low operating temperature (60-80°C) reduce energy costs and prevent thermal degradation.
- Customizable Capacity – Available in various sizes from 500 L/h to 5000 L/h, tailored to your production volume.
- Easy Maintenance – Modular design with quick-access ports for inspection and cleaning, reducing downtime.

Frequently Asked Questions (FAQ)
Q1: What is the main application of this evaporation system?
A: It is specifically designed for PDV (Pure Dried Vacuum) salt production, but it can also be used for concentrating other brine solutions or industrial liquids with similar properties.
Q2: Can the system handle different feed concentrations?
A: Yes, the PLC control allows you to adjust parameters according to the feed brine concentration. The system is designed to handle a wide range of salt concentrations (e.g., 10%–30% NaCl).
Q3: What is the lifespan of the equipment?
A: With proper maintenance, the 304 stainless steel construction can last 15-20 years or more. Regular cleaning and inspection will maximize service life.
Q4: Do you provide installation and commissioning services?
A: Yes, we offer on-site installation guidance and commissioning support. Our technical team can also provide remote assistance if needed.
Q5: What is the power consumption of a typical system?
A: Power consumption depends on capacity and number of effects. For example, a 1000 L/h 3-effect system consumes approximately 50-70 kW. We can provide detailed energy data based on your requirements.
Q6: Is the system customizable for different salt grades?
A: Yes, we can adjust the evaporation parameters and optional add-ons (e.g., crystal size control, washing stages) to produce various salt grades such as industrial salt, food-grade salt, or pharmaceutical salt.
Q7: What certifications does the equipment have?
A: Our manufacturing process follows industry standards, and we have obtained relevant product certifications (others). Specific certifications can be provided upon request depending on the destination country.
Q8: How long does delivery take?
A: Lead time is typically 30-45 days after order confirmation, depending on the complexity and customization. We ship from Tianjin, Qingdao, or Shanghai ports.
