Falling Film Evaporator

A falling film evaporator is an advanced thermal separation system widely used in food, pharmaceutical, dairy, and chemical industries. It works by evenly distributing liquid as a thin film along heated surfaces, allowing rapid evaporation at lower temperatures. This gentle process preserves product quality while ensuring high efficiency and energy savings, making it one of the most reliable solutions for large-scale concentration needs.

Falling Film Evaporator

 

The falling film evaporator is an advanced liquid concentration system widely applied in the food, beverage, pharmaceutical, and chemical industries. Known for its efficiency, reliability, and energy savings, this equipment is designed to handle heat-sensitive materials with precision. It is an essential solution for businesses seeking high productivity and consistent results.


Falling Film Evaporator Working Principle

 

The falling film evaporator working principle is based on distributing liquid as a thin film along the inner walls of vertical heating tubes. As the liquid flows downward, heat transfer occurs rapidly, allowing evaporation to happen under controlled vacuum or atmospheric conditions. This ensures fast concentration, minimal thermal degradation, and stable product quality, making it suitable for temperature-sensitive substances such as juices, milk, herbal extracts, and solvents.


Durable Construction and Advanced Design

 

Built with high-grade stainless steel, the evaporator falling film guarantees long service life, corrosion resistance, and easy cleaning. Its vertical tubular structure minimizes scaling, reduces maintenance, and supports continuous operation. Automated temperature, pressure, and flow controls improve safety and efficiency, ensuring consistent output across industries.


Applications Across Industries

 

The falling film evaporator is widely used for:

•  Food and Beverage: Concentration of juices, milk, and syrups

•  Pharmaceutical: Herbal extractions, medicinal liquids, and active ingredients

•  Chemical: Solvent recovery, liquid concentration, and industrial solutions
