Labmate Falling Film Evaporator offer evaporation rates from 15 to 700 L/h with its durable glass or stainless steel build. They evenly distribute liquid into heat exchange tubes, forming uniform downward film. These operate under vacuum and low-temperature conditions to preserve material integrity. Their continuous feeding and discharging, reduce labor costs and operation time. Our Falling Film Evaporator is ideal for solvent recovery, concentration, and crystallization.
Frequently Asked Questions
1 What is a Falling Film Evaporator?
A Falling Film Evaporator is a heat exchanger designed to use a thin film of liquid flowing down vertical tubes to efficiently concentrate solutions by evaporating the solvent.
2 How does Falling Film Evaporator work?
It works by allowing a liquid to flow as a thin film over heated tubes, where it evaporates in order to concentrate the solution.
3 Does temperature affect the performance of Falling Film Evaporator?
The temperature difference between the liquid and the heated tube surface impacts evaporation rate.
4 Can Falling Film Evaporator operate under vacuum conditions?
It can operate under vacuum in order to lower the boiling point of the solvent.
5 What is the difference between a Rising Film Evaporator and a Falling Film Evaporator?
In Rising Film Evaporator, the liquid moves upward in the tubes due to the force of vapor rising whereas a Falling Film Evaporator relies on gravity for downward movement.
6 Can Falling Film Evaporator be used for solvent recovery?
It is used for solvent recovery in industries like chemical and pharmaceutical manufacturing.
7 How does Falling Film Evaporator impact product quality?
It helps in maintaining the integrity of heat-sensitive compounds thereby ensuring higher quality products.
8 Can Falling Film Evaporator be used in continuous processes?
It is commonly used for continuous operations.
9 Is Falling Film Evaporator suitable for large-scale industrial operations?
It is suitable for large-scale industrial operations.
10 Can Falling Film Evaporator be used for environmental applications?
It is widely used in environmental applications such as wastewater treatment.
Selection Guide for Falling Film Evaporator
Falling Film Evaporator is an efficient thermal separation system used for concentrating heat-sensitive or low-viscosity liquids in various industries, including pharmaceuticals, food and beverage, dairy, chemicals, and wastewater treatment. When selecting a suitable model, key factors include the nature of the application, feed liquid characteristics, and desired processing capacity. The system should offer efficient heat transfer with minimal thermal degradation, especially for sensitive materials. Selection should consider evaporation rate, heat transfer surface area, and the number of effects. Single-effect systems are simpler, while multi-effect units provide better energy efficiency. The material of construction, typically stainless steel (SS304 or SS316L), should ensure chemical compatibility and hygiene. Vacuum compatibility is essential for handling delicate products at reduced temperatures. Models with advanced automation, PLC controls, and CIP/SIP features improve ease of use and compliance with GMP standards. Additionally, certifications like CE, ISO, or ASME validate quality and industry readiness, making them crucial for regulatory approval and safe operation.
Understanding Falling Film Evaporator: Purpose, Process, and Benefits
Falling Film Evaporator is a type of heat exchanger designed to evaporate volatile components, usually water or solvents, from a liquid mixture. In this system, the liquid is evenly distributed across the inside walls of vertical tubes, forming a thin film. As the liquid film flows downward due to gravity, it is heated by steam or another heat source applied to the outside of the tubes. The heat causes the solvent to evaporate while the concentrated solution flows downward and collects at the bottom.
Our Evaporator is designed for rapid and efficient heat transfer while minimizing product exposure to high temperatures. It features;

Multiple Effect Operation
Wide Operating Range
Falling Film Evaporator is widely used across multiple industries due to their efficient heat transfer and gentle processing of heat-sensitive materials. In the food and beverage industry, they are employed for concentrating fruit juices, dairy products, sweeteners, and flavor extracts while preserving nutritional and sensory qualities. The pharmaceutical industry utilizes them to concentrate active pharmaceutical ingredients (APIs), herbal extracts, and other sensitive compounds without thermal degradation. In the chemical industry, Falling Film Evaporator essential for solvent recovery, concentration of chemical solutions, and purification processes. The wastewater treatment sector applies falling film evaporators to minimize waste volumes and recover valuable components from industrial effluents. In desalination plants, they help remove salts from seawater to produce potable water. Additionally, the cosmetics and personal care industry uses them for concentrating formulations like essential oils, fragrances, and active ingredients. Falling Film Evaporator’s versatility also extends to biofuel production, where they assist in concentrating bioethanol or biodiesel intermediates efficiently.
