Product Description

Pillow Plate Falling Film Evaporator Customized SS304

Customized SS304 pillow plate falling film evaporator with laser-welded dimple plates

Laser-welded pillow plate panels in SS304 form the heating surfaces of this falling film evaporator, delivering high heat-transfer area density with wide, non-clogging channels. The design supports gentle vacuum evaporation, uniform film distribution, and easy cleanability. Configurable for food, chemicals, and environmental duties, with optional TVR/MVR for enhanced energy efficiency.

Key Benefits

Efficient heat transfer: Turbulent flow inside pillow plates boosts coefficients at low ΔT.
Fouling tolerance: Wide channels handle particulates and viscous feeds better than narrow-gap plates.
Uniform film: Optimized distributors ensure even wetting, stable evaporation, and product quality.
Hygienic & serviceable: Smooth SS304 surfaces, CIP-ready geometry, easy access for inspection.
Scalable & modular: Add/remove plates to match capacity; upgrade path to TVR/MVR to cut OPEX.

Process & Thermal Economy

Feed is preheated and distributed as a thin film over pillow plate panels under vacuum. Evaporation occurs at low temperature; vapor is separated and condensed. Optional TVR or MVR recycles latent heat, lowering specific energy consumption while maintaining product quality.

Materials & Cleanability

Standard wetted materials: SS304 pillow plates and headers; options include SS316L/duplex/Ti for chloride or corrosive service. Sanitary finishes, drainable piping, CIP spray devices, and validated cleaning recipes available.

Process Overview -- Pillow Plate Falling Film

Flow diagram of pillow plate falling film evaporation process

Feed conditioning: screening/filtration, pH trim, antiscalant as required.
Falling film (vacuum): uniform distribution over pillow plates; low ΔT to protect product.
Vapor handling: separator -> condenser; optional TVR/MVR for energy recovery.
Condensate: polishing to reuse or discharge spec (conductivity/TOC guard optional).
Concentrate routing: to crystallizer/centrifuge/dryer or recycle per flowsheet.

Key Components

Laser-welded SS304 pillow plate evaporator stack with distributors and collectors
Vapor-liquid separator, surface condenser, vacuum/NCG handling skid
Preheaters/heat-recovery exchangers; optional TVR ejector or MVR compressor
Instrumentation (T/P/flow/cond/level), PLC/HMI/SCADA with historian
CIP skid and chemical dosing for scale control

Performance & Sizing

Parameter	Typical Range*
Operation	Continuous, vacuum duty
Film ΔT	Low (design-dependent) for gentle evaporation
Steam economy	SE ~1.0 (single effect); higher with TVR/MVR
Viscosity window	Low to medium-high; wide channels improve tolerance
Materials	SS304 standard; SS316L/duplex/Ti optional

*Actual performance depends on feed composition, fouling tendency, and selected energy-recovery option.

FAQ

When choose pillow plate over shell-and-tube?
Pillow plates offer compact area, wide channels, and easy modular scaling--ideal for moderate fouling and hygienic duties.

Can the unit be upgraded to MVR later?
Yes. The pillow plate body can integrate TVR initially and be upgraded to MVR to further reduce specific energy use.

Is SS304 sufficient for chloride service?
For elevated chlorides or aggressive chemistry, we recommend SS316L/duplex or Ti for improved corrosion resistance.
