Evaporators in India
India has transformed itself into a hub for developing advanced evaporator systems and solutions for industrial applications. Leading companies such as Goldfinch Evaporators manufacture efficient and environment-friendly evaporation systems. The following blog discusses the different types of evaporators used, applications thereof, and choosing the right evaporator.
What Are Evaporators?
Evaporators are machines that convert liquids to vapor by adding heat to them. They are now a salient feature of industries like food processing, chemical processing, and waste treatment.
Types of Evaporators
Thin film Evaporators
These types of evaporators are meant just to be used for the heat-sensitive materials. The possible thermal degradation should be at a minimum. Their applications include the pharmaceutical and chemical industries.
Forced Circulation Evaporators
These evaporators are designed for solutions prone to fouling or scaling. They maintain high efficiency even with viscous liquids.
Wiped Film Evaporators
Wiped film evaporators are better suited for evaporating and condensing use in the separation of high boiling mixtures They’re efficient for processing thermally sensitive products.
Agitated thin-film evaporators
Known for handling difficult materials, these evaporators prevent fouling and provide consistent performance.
Multi-Effect Evaporators
Multi-effect evaporators improve energy efficiency by reusing steam. They are widely used in the desalination and food industries.
Which Type of Evaporator is Best?
High-agitation thin-film evaporators are extensively recommended for challenging materials. While tubular evaporators are versatile, they’re less effective for heat-sensitive or viscous liquids.
Examples of Evaporators
- Rotary evaporators
- Natural/forced circulation evaporators
- Falling film evaporators
- Rising film (long tube vertical) evaporators
- Agitated thin-film evaporators
The Principle of Evaporators
Evaporators operate on the principle of heat transfer, where heat energy transforms liquid into vapor. This process is enhanced by surface area, temperature control, and pressure conditions.
Applications of Evaporators
Chemical Industry
Used for concentrating solutions and recovering solvents.
Food Industry
For the production of concentrated products such as condensed milk, fruit juices, and the like.
Pharmaceutical Industry
Facilitates the production of APIs and other formulations.
Lifecycle Wastewater
Removes water content to minimize waste volume.
Renewable Energy
Assists in biofuel production and energy recovery.
Advantages of Falling Film Evaporators
Maximizing Effectiveness: Transfer as much heat as possible to the least possible energy.
Multipurpose: Suitable for various liquids.
Economical: Low operational cost.
Green Technology: Low carbon footprint.
Evaporator Selection Criteria
- Material Properties
- Consider solubility, temperature sensitivity, and viscosity.
- Operational Parameters
- Assess pressure, temperature, and scale deposition tendencies.
- Material of Construction
- Choose corrosion-resistant materials for durability.
