Product Description
Laser-welded embossed pillow plates combined with MVR (Mechanical Vapor Recompression) technology create a compact, energy-saving evaporator body with wide channels, strong turbulence, and hygienic surfaces. The design supports gentle vacuum evaporation, low ΔT operation, and continuous 24/7 duty for food, chemical, and environmental applications.
Key Benefits
- Energy Saving: MVR recycles latent heat with minimal fresh steam required after start-up
- High Heat Transfer: Embossed pillows promote turbulence and coefficients at low ΔT
- Fouling Tolerance: Wide channels handle particulates and viscosity better than narrow-gap plates
- Hygienic & Serviceable: SS304/SS316L surfaces, drainable geometry, CIP-ready, easy inspection
- Modular Scaling: Add/remove plate banks with upgrade path to TVR/MVR hybrids
Process & Thermal Economy
Secondary vapor is mechanically compressed to raise saturation temperature and reused as the heating medium. Uniform film distribution over pillow plates under vacuum maintains high heat-transfer coefficients and protects heat-sensitive products, reducing specific energy consumption.
Materials & Construction
Laser-welded SS304/SS316L pillow plates and manifolds with duplex/Ti/Hastelloy options available. Orbital-welded headers, sanitary finishes, slope-to-drain piping, and validated CIP documentation available for food-grade compliance.
Process Overview
- Feed Conditioning: Screening/filtration, pH trim, antiscalant to limit Ca/Mg/Si scaling
- Falling-Film Duty: Even wetting across embossed plates with tight ΔT/LMTD control
- MVR Compression: VFD-driven compressor sets discharge pressure for capacity/ΔT control
- Condensate Polishing: Filters/RO/AC for reuse or compliant discharge with conductivity/TOC guard
- Concentrate Routing: To crystallizer/centrifuge/dryer or recycle per ZLD/production needs
Key Components
- Laser-welded embossed pillow plate evaporator stack with distributors/collectors
- MVR mechanical vapor compressor (turbo/Roots) with VFD
- Vapor-liquid separator, surface condenser, vacuum/NCG handling skid
- Preheaters/heat-recovery HX; PLC/HMI/SCADA with historian
- CIP skid; antiscalant dosing; T/P/flow/conductivity/level instrumentation
Performance & Sizing
| Parameter | Typical Range |
|---|---|
| Operation | Continuous, vacuum duty |
| Electric Use (MVR) | 15-40 kWh per ton of water evaporated |
| Film ΔT | Low for quality preservation |
| Steam Demand | Very low after start-up |
| Materials | SS304 / SS316L standard; duplex/Ti/Hastelloy optional |
*Performance depends on feed chemistry/viscosity, fouling tendency, compression ratio, and plate geometry.
Frequently Asked Questions
Why choose embossed pillow plates?
Embossing increases turbulence and stiffness, improving heat-transfer coefficients and pressure tolerance at low ΔT.
Can the system be expanded later?
Yes - add plate banks or integrate TVR/MVR hybrid modules to increase capacity and reduce specific energy use.
Which stainless grade should we pick?
SS316L is preferred for chlorides/corrosives; SS304 suits benign duties. Duplex/Ti/Hastelloy available per corrosion study.
Applications
Ideal for food evaporation, chemical concentration, and high-salinity wastewater reduction applications requiring energy-efficient vacuum evaporation technology.
