Evaporators

How Do Evaporators Work?

Evaporators operate on the principle of heat transfer and phase change. Here’s a step-by-step breakdown of the evaporation process:

1. Heat Input: We apply heat to the solution, typically through steam or hot water.
2. Boiling: The heat causes the solvent (usually water) to boil and transform into vapor.
3. Vapor Separation: We separate the vapor from the remaining concentrated solution.
4. Condensation: We then condense the vapor back into liquid form for reuse or disposal.

The efficiency and effectiveness of an evaporator depend on its design, type, and the specific requirements of the application.

Types of Evaporators

There are several types of evaporators, each suited for different applications and industries. At Acmefil, we specialize in manufacturing a wide range of evaporators to meet diverse industrial needs. Let’s explore the main types of evaporators:

1. Falling Film Evaporators
2. Thin Film Evaporators
3. Forced Circulation Evaporators
4. Wiped Film Evaporators
5. Agitated Thin Film Evaporators
6. Multi-Effect Evaporators

1. Falling Film Evaporators

We use falling film evaporators in industries where gentle heat treatment and short residence time are crucial. These evaporators distribute the liquid evenly over the inner surface of vertical tubes. The liquid forms a thin film, which flows downward under the influence of gravity. As it descends, the liquid heats up, causing the solvent to evaporate.

Advantages:

• High heat transfer efficiency
• Suitable for heat-sensitive materials
• Minimal fouling and scaling

Applications:

• Dairy and food industries
• Pharmaceutical manufacturing
• Chemical processing

2. Thin Film Evaporators

We design thin film evaporators, also known as wiped film evaporators, for the efficient evaporation of highly viscous and heat-sensitive products. These evaporators form a thin film of the liquid on a heated surface. A rotating wiper or blade spreads the liquid into a thin film, enhancing heat transfer and preventing fouling.

Advantages:

• Effective for high-viscosity solutions
• Low thermal degradation of products
• Continuous operation

Applications:

• Distillation of heat-sensitive compounds
• Concentration of viscous solutions
• Solvent recovery

3. Forced Circulation Evaporators

We recommend forced circulation evaporators for handling solutions with a high tendency to scale or crystallize. These evaporators use a pump to circulate the liquid through a heat exchanger, where it heats up before entering the evaporator body. The heated liquid then flashes into vapor, and the process repeats.

Advantages:

• Handles scaling and fouling liquids efficiently
• High heat transfer rates
• Suitable for large-scale operations

Applications:

• Wastewater treatment
• Chemical manufacturing
• Brine concentration

4. Wiped Film Evaporators

We specialize in wiped film evaporators for processing high-viscosity and heat-sensitive materials. These evaporators use a rotating wiper to spread the liquid into a thin film on the heated surface. The thin film allows for rapid evaporation and minimizes thermal degradation.

Advantages:

• Handles viscous and heat-sensitive materials
• High evaporation rates
• Continuous operation with minimal maintenance

Applications:

• Pharmaceutical production
• Essential oil extraction
• Polymer and resin processing

5. Agitated Thin Film Evaporators

We use agitated thin film evaporators for highly viscous and foaming liquids. These evaporators include additional mechanical agitation, which enhances the heat transfer and evaporation rates.

Advantages:

• Enhanced heat transfer
• Suitable for foaming and highly viscous liquids
• Minimal fouling

Applications:

• Concentration of polymer solutions
• Processing of heat-sensitive materials
• Solvent recovery

6. Multi-Effect Evaporators

We design multi-effect evaporators to improve energy efficiency by using the vapor generated in one effect as the heating medium for the next effect. These evaporators consist of multiple stages or effects, where each subsequent effect operates at a lower pressure.

Advantages:

• High energy efficiency
• Reduced operating costs
• Suitable for large-scale applications

Applications:

• Desalination of seawater
• Concentration of fruit juices
• Wastewater treatment

7. Rising Film Systems

Rising film systems are ideal for liquids that tend to foam. In these devices, the liquid is introduced at the bottom of the vertical tubes and heated. As it heats up, vapor forms and pushes the liquid upward, creating a thin film that evaporates quickly.

Advantages:

• Effective for foaming liquids
• High heat transfer efficiency
• Quick evaporation

Applications:

• Concentration of fruit juices
• Dairy product processing
• Chemical solutions
