Plate-Type Vacuum Evaporator

EasyReal’s plate-type vacuum evaporator is a compact solution for concentrating clear or low-solid liquids at low temperature—ideal for coconut water, clarified fruit juice, whey/permeate, soy sauce, herbal extracts, and similar heat-sensitive products. It combines a high-efficiency plate heat transfer surface with vacuum boiling and reliable vapor–liquid separation to deliver stable concentration with minimal footprint.

Typical capacity: 100–35,000 L/h (final sizing depends on product properties and concentration ratio).

Plate-Type Vacuum Evaporator Applications

Food & Beverage
• Coconut water concentration (low temperature vacuum operation to protect freshness)
• Clarified apple/pear/grape juice concentrates
• Dairy ingredients (whey, permeate, milk-based liquids with controlled fouling)
• Condiments & extracts (soy sauce, botanical extracts, functional beverage bases)
Bio/Pharma & Chemical (optional design)
• Solvent recovery / product concentration where corrosion-resistant materials are required
If your product contains high pulp, fibers, or heavy fouling solids, ask us for falling-film or forced-circulation options instead.

How a Plate-Type Vacuum Evaporator Works

1. Feed & preheating: Product enters a plate heat section and is brought close to boiling temperature under vacuum.
2. Vacuum evaporation: Reduced pressure lowers boiling temperature, helping protect heat-sensitive liquids.
3. Separation: Vapor is separated from concentrate in the evaporation chamber to prevent entrainment.
4. Condensation: Vapor is condensed (plate condenser option) and collected as condensate.
5. Discharge & control: Concentrate is discharged via pump; temperature, vacuum, and flow are controlled by PLC.
Optional energy-saving upgrade — TVR (steam thermocompressor):
Thermal vapor recompression reuses part of the generated vapor as heating vapor to reduce live steam demand and operating cost.

Configurations (Single-Effect / Multi-Effect)

• Single-effect plate evaporator: best for moderate concentration targets, simple utilities, fast start-up.
• Multi-effect plate evaporator: better steam economy for larger capacities and higher water removal.
• TVR-assisted system (optional): improved steam efficiency using a thermocompressor.

Key Features (Why Plate Evaporation)

• High heat-transfer efficiency: plate patterns promote turbulence for fast heat exchange.
• Compact footprint: plate packs provide large surface area in a small space.
• Low-temperature concentration under vacuum (better for aroma and color retention).
• Hygienic, service-friendly design: plate packs can be opened for inspection, gasket change, and cleaning.
• Flexible sizing: add/remove plates and tailor surface area to capacity changes.

Selection Guide (When to Choose Plate vs Other Evaporators)

Choose a plate evaporator when:
• Product is clear / low pulp, low-to-medium viscosity
• You need compact installation, fast cleaning, quick turnaround
• You want low-temperature vacuum operation for delicate liquids
Consider falling film / forced circulation when:
• Product has high solids, heavy pulp/fibers, high fouling, or very high viscosity
• You need strong anti-fouling circulation and longer run time between CIP

Standard Scope of Supply

• Evaporation chamber + balance tank
• Plate preheater section
• Plate condenser
• Feed/discharge/condensate pumps
• Vacuum system
• Steam thermocompressor (TVR) option
• Instrumentation (temperature / pressure / flow)
• Siemens PLC control system with operator interface (HMI)
• CIP-ready design (CIP module optional depending on project)
Materials (typical): Product-contact parts in SUS316L / SUS304; other corrosion-resistant options available on request.

Technical Parameters (Typical Range)

• Capacity: 100–35,000 L/h
• Operating temperature: 40–90°C (depends on vacuum level and product)
• Steam pressure: 0.2–0.8 MPa
• Heat transfer area: 5–200 m²
• Plate material: SUS316L / SUS304 / titanium (as required)
Final energy consumption depends on feed °Brix, target °Brix, effects/TVR selection, and utilities.

FAQ

Q1: Can a plate evaporator handle pulp or fibers?

It’s best for clarified or low-solid liquids. For high pulp/high fouling, ask for falling film or forced circulation.

Q2: Is TVR the same as MVR?

No. TVR uses a steam thermocompressor to recompress vapor; it reduces live steam demand and improves efficiency.

Q3: What do you need to size the evaporator?

Feed flow (L/h), main structure, inlet/outlet °Brix, solids/viscosity, evaporation allowable temperature, vacuum degree,foaming, and utilities consumption(steam/cooling water/air compresser /power).
