AGITATED THIN FILM EVAPORATOR
An Agitated Thin Film Evaporator (ATFE) is a specialized type of evaporator used for highly viscous, heat-sensitive, or fouling-prone materials. It employs a thin film of liquid spread over a heated surface to achieve rapid evaporation and separation of volatile components.
KEY FEATURES OF AGITATED THIN FILM EVAPORATOR
1. Agitated Film Formation: A rotating agitator distributes the liquid as a thin, uniform film over the heated surface.
2. Low Residence Time: Minimal contact time between the product and heated surface reduces thermal degradation.
3. Operation Under Vacuum: Operates at low pressures to lower boiling points, making it ideal for heat-sensitive materials.
4. Wide Viscosity Range: Can handle feed materials with viscosities ranging from low to extremely high (up to 100,000 cP).
Applications of agitated thin flim evaporator
1. Pharmaceutical Industry: Concentration and purification of APIs (Active Pharmaceutical Ingredients).
2. Chemical Industry: Distillation of high-boiling or heat-sensitive chemicals.
3. Food & Beverage Industry: Concentration of fruit juices, flavors, and dairy products.
4. Wastewater Treatment: Recovery of reusable components from waste streams.
Technical Specifications
1. Heat Transfer Area: Typically ranges from 0.1 m² to 20 m² or more, depending on application.
2. Operating Pressure: Vacuum up to 1 mbar or lower for heat-sensitive materials.
3. Material of Construction:
Stainless Steel (304, 316): For general and hygienic applications.
4. Alloy Materials (Hastelloy, Inconel): For corrosive or high-temperature materials.
5. Viscosity Handling: Capable of processing materials with viscosities up to 100,000 cP.
6. Temperature Range: Up to 350°C or more, depending on the application.
