As a manufacturer with over 25 years of industry experience (since 1998), Anping County Boli Hardware Wiremesh Products Factory brings you a high-performance evaporation solution: the Evaporation Capacity 500kg/h 316L Stainless Steel Sugar Board-Type Automatic Salt Line MVR Tube Evaporator. This equipment is designed for efficient concentration of sugar solutions, brine, and other heat-sensitive liquids, combining board-type and tube-type heat transfer surfaces to maximize thermal efficiency and minimize fouling. Our MVR (Mechanical Vapor Recompression) technology significantly reduces energy consumption compared to traditional multi-effect evaporators, making it an ideal choice for cost-conscious production lines.
Built with premium 316L stainless steel, this evaporator offers excellent corrosion resistance against chlorides and acidic media, ensuring long service life even in harsh salt and sugar processing environments. The automatic control system allows for precise operation, reducing labor costs and human error. Whether you are producing refined sugar, table salt, or industrial brine, this evaporator delivers consistent, high-quality concentration results.
Key Features & Benefits:
- High Evaporation Capacity: 500 kg/h, suitable for medium-scale production lines.
- MVR Technology: Reduces steam consumption by up to 60-80% compared to conventional evaporators, lowering operational costs.
- 316L Stainless Steel Construction: Resists pitting, crevice corrosion, and stress corrosion cracking, especially in chloride-rich environments.
- Board-Type + Tube Bundle Design: Combines high heat transfer coefficients of plate heat exchangers with the robustness of tubular evaporators, handling high-viscosity and scaling-prone liquids effectively.
- Automatic Salt Line Operation: Integrated with automatic salt discharge and cleaning functions, minimizing downtime.
- PLC Control (Optional): Enables remote monitoring, data logging, and precise temperature/pressure control.
- Compact Footprint: Space-saving design ideal for factory retrofits or new installations.
- Easy Maintenance: Modular construction allows quick access to heating surfaces for cleaning and inspection.

Detailed Product Description:
The MVR tube evaporator operates on the principle of mechanical vapor recompression: the vapor generated from the boiling liquid is compressed by a centrifugal compressor, raising its temperature and pressure, and then returned to the heating chamber as the heating medium. This cycle recovers the latent heat of vaporization, drastically reducing the need for fresh steam. The board-type (plate) preheater section uses corrugated plates to achieve high turbulence and heat transfer, while the tubular falling-film or forced-circulation section handles the main evaporation. This hybrid design is particularly effective for sugar solutions, where viscosity increases during concentration, and for salt solutions, where scaling and crystallization are common.
The automatic salt line feature is critical for continuous operation in salt production. The evaporator includes a salt leg or cyclone separator with automatic discharge valves, which periodically removes precipitated salt crystals without interrupting the process. The PLC-based control system can be programmed to adjust the discharge frequency based on conductivity or density measurements, ensuring stable product quality.
Our factory has been exporting to major markets worldwide, including North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, the Middle East, and Western Europe. With an annual export value of US$5-10 million, we have established a reliable supply chain and quality control system. Each evaporator undergoes rigorous testing before shipment, including hydrostatic pressure tests, performance verification, and electrical checks. We provide comprehensive documentation (P&ID, layout drawings, operation manual) and offer on-site commissioning support upon request.

Frequently Asked Questions (FAQ):
-
Q: What is the difference between MVR and multiple-effect evaporation?
A: MVR uses a mechanical compressor to recompress vapor, recycling its latent heat, while multiple-effect uses a series of vessels at decreasing pressures. MVR typically consumes less steam and is more energy-efficient for single-effect equivalent capacities. -
Q: Can this evaporator handle highly viscous liquids like molasses?
A: Yes, the board-type preheater and tube bundle design can handle moderate viscosities. For very high viscosities, we recommend a forced-circulation configuration. Please provide your specific product properties for a tailored solution. -
Q: What is the required steam quality and pressure?
A: The system typically requires a small amount of startup steam (e.g., 0.3-0.5 MPa saturated). During normal operation, steam is only needed for compensation of heat losses, usually less than 5% of the total evaporation energy. -
Q: How do you prevent scaling in salt line applications?
A: The automatic salt discharge system removes crystals before they cause scaling. Additionally, the 316L material and smooth surfaces reduce adhesion. Periodic CIP (clean-in-place) cycles can be programmed. -
Q: What is the warranty period?
A: Standard warranty is 12 months from shipment or 18 months from installation, whichever comes first. Extended warranties are available upon request. -
Q: Do you provide installation services?
A: We can arrange on-site supervision and commissioning by our engineers. Travel expenses and per diem are quoted separately. -
Q: Can the control system be integrated with my existing DCS?
A: Yes, our PLC supports common communication protocols such as Modbus, Profibus, or Ethernet/IP. Custom integration is available. -
Q: What are the shipping ports?
A: We ship from Tianjin, Qingdao, and Shanghai ports. FOB, CIF, or other terms are negotiable.
