Laser Welding Enbossed Pillow Plate MVR Evaporators

Laser Welding Enbossed Pillow Plate MVR Evaporators
Laser-welded embossed pillow plate MVR evaporator for high-efficiency vacuum evaporation

Laser-welded embossed pillow plates combined with MVR (Mechanical Vapor Recompression) 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; minimal fresh steam after start-up.
  • High heat transfer: Embossed pillows promote turbulence and coefficients at low ΔT.
  • Fouling tolerance: Wide channels handle particulates/viscosity better than narrow-gap plates.
  • Hygienic & serviceable: SS304/SS316L surfaces, drainable geometry, CIP-ready, easy inspection.
  • Modular scaling: Add/remove plate banks; 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 (duplex/Ti/Hastelloy optional). Orbital-welded headers, sanitary finishes, slope-to-drain piping, and validated CIP documentation available for food-grade compliance.

Process Overview — Pillow Plate MVR
Flow: feed conditioning → pillow plate falling-film evaporation (vacuum) → MVR compression → condensate polishing → concentrate/crystals handling
  • Feed conditioning: screening/filtration, pH trim, antiscalant to limit Ca/Mg/Si scaling.
  • Falling-film duty: even wetting across embossed plates; 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 (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
ParameterTypical Range*

Electric use (MVR)~15–40 kWh per ton of water evaporated (duty/CR dependent)
Film ΔTLow for quality preservation; set via compressor discharge pressure
Steam demandVery low after start-up (backup/ancillary only)
MaterialsSS304 / SS316L standard; duplex/Ti/Hastelloy optional

*Performance depends on feed chemistry/viscosity, fouling tendency, compression ratio, and plate geometry.

FAQ
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.

Application
Applications: food evaporation, chemical concentration, and high-salinity wastewater reduction with laser-welded pillow plate MVR
