Anping County Boli Hardware Wiremesh Products Factory (established in 1998) is a trusted manufacturer exporting US$5-10 million annually to global markets. Our Multi-Effect Vacuum Evaporation of Salts system is specifically engineered for pharmaceutical salt recovery applications, delivering high-efficiency concentration and crystallization while minimizing energy consumption. With decades of fabrication experience, we ensure robust construction, precise control, and lasting performance for demanding industrial environments.
This advanced evaporation system utilizes multiple effect stages operating under vacuum to significantly reduce boiling point, enabling gentle treatment of heat-sensitive pharmaceutical salts. The closed-loop design prevents contamination and maximizes product purity. Ideal for recovering sodium chloride, potassium chloride, ammonium sulfate, and other salts from process streams, it helps manufacturers achieve zero liquid discharge (ZLD) goals and reduce waste disposal costs.
Key Features & Technical Advantages
- Multi-Effect Design – Up to 5 effects for maximum energy efficiency (steam consumption reduced by 50-70% compared to single-effect).
- Vacuum Operation – Low-temperature evaporation (40-80°C) protects thermal-sensitive compounds and reduces scaling.
- Corrosion-Resistant Materials – Constructed from SS304/316L with optional Hastelloy or titanium for aggressive chloride environments.
- Automated Control – PLC-based system with touchscreen HMI for precise temperature, pressure, and feed rate management.
- Compact Footprint – Vertical or horizontal layout saves floor space and simplifies installation.
- Easy Maintenance – Quick-opening doors, CIP spray balls, and accessible heating surfaces reduce downtime.
- High Recovery Rate – Salt recovery >95% (depending on feed composition and operating conditions).

Frequently Asked Questions (FAQ)
-
What types of salts can this system recover?
It handles common pharmaceutical salts like NaCl, KCl, NH4Cl, Na2SO4, and MgSO4. For aggressive chlorides, we offer Hastelloy or titanium options. -
How does multi-effect vacuum evaporation save energy?
Each effect reuses vapor from the previous effect as heating medium, drastically reducing fresh steam consumption. For example, a 3-effect system uses about 0.3 kg steam per kg evaporated water, versus 1.1 kg for single-effect. -
What is the typical recovery rate?
Under optimal conditions, salt recovery exceeds 95%. Actual rate depends on feed concentration, impurities, and operating parameters. -
Can the system be automated?
Yes, we offer PLC-based automatic control with touchscreen interface, including temperature, pressure, and feed rate regulation. Remote monitoring available upon request. -
What materials are used for construction?
Standard is SS304 or SS316L. For high chloride or acidic feeds, we recommend duplex stainless steel, Hastelloy C276, or titanium. -
What is the minimum order quantity (MOQ)?
MOQ is 1 set. We welcome both small-scale lab units and large industrial systems. -
Do you provide installation and commissioning support?
Yes, we offer on-site technical guidance and remote assistance. Detailed manuals and drawings are included. -
How long is the warranty?
Standard warranty is 12 months from commissioning or 18 months from shipment, whichever comes first. Extended warranty available.
