Falling Film Evaporator

Falling Film Evaporator

Description:

A Falling Film Evaporator is a type of heat exchanger designed for the concentration of heat-sensitive liquids. It works by allowing the liquid to form a thin film along the inside surface of vertical tubes, where it is evaporated using external heat, usually steam. The liquid flows down due to gravity, and the vapor is separated from the liquid as it descends.

This equipment is highly efficient for processes requiring gentle heat treatment, minimal product degradation, and continuous operation.

Where It’s Used:

Food & Beverage industry
Dairy processing plants (milk, whey, juice concentration)
Pharmaceutical and chemical industries
Paper and pulp industry
Sugar refining and ethanol plants
Herbal and nutraceutical extraction units
Desalination and water treatment plants

Uses:

Concentration of liquids (juices, milk, pharma solutions)
Solvent recovery and distillation
Pre-concentration before drying
Wastewater treatment and volume reduction
Alcohol and extract concentration
Removal of volatile substances from liquids

Importance:

Enables processing of heat-sensitive products with minimal degradation
Offers high heat transfer coefficients with energy efficiency
Supports large-scale continuous production
Helps reduce production cost through solvent reuse
Compact design suitable for space-constrained facilities
Integral in achieving high-purity outputs in pharma and food

Significance in Industry:

Energy Efficiency: Operates at low temperature differentials and can integrate with MVR (Mechanical Vapor Recompression) for energy savings
Product Quality: Preserves taste, aroma, and nutritional value in food and beverages
Reduced Fouling: Falling film design minimizes scale formation and fouling
Modularity: Can be scaled or configured with multiple effects for higher throughput
Low Residence Time: Makes it ideal for thermally sensitive materials

FAQs:

What is a falling film evaporator?
→ A thermal equipment used to concentrate liquids by forming a thin film on heated surfaces.
How does it differ from a rising film evaporator?
→ Falling film uses gravity, has lower residence time, and is better for heat-sensitive materials.
What materials are used to manufacture it?
→ Usually SS304, SS316L, or other food/pharma-grade stainless steel.
What are the energy-saving features?
→ Integration with MVR/TVR systems, multiple effects for reuse of vapor energy.
Is it suitable for viscous liquids?
→ Works best with low to moderate viscosity liquids.
Can it be automated?
→ Yes, fully automatic PLC-based systems are common.
What are its cleaning requirements?
→ CIP (Clean-In-Place) systems are usually included for hygiene and maintenance.
How is capacity measured?
→ Typically in Liters per Hour (LPH) or Tons per Day (TPD), based on evaporation rate.
Does it handle corrosive materials?
→ Special alloys or coatings can be used for corrosive media.
What industries benefit most from this system?
→ Dairy, pharma, food, biofuels, chemicals, and water treatment.
