FAQs on Agitated Film Evaporator Video Lecture - Heat Transfer - Mechanical Engineering
| 1. What is an agitated film evaporator? |  |
Ans. An agitated film evaporator is a type of evaporator used in the chemical engineering industry. It consists of a heated cylindrical vessel with a rotating agitator that creates a thin film of liquid on the vessel walls. This design allows for efficient evaporation of volatile components from the liquid.
| 2. How does an agitated film evaporator work? | |
Ans. In an agitated film evaporator, the liquid to be evaporated is fed into the heated vessel. The rotating agitator creates a thin film of liquid on the vessel walls, which increases the surface area available for evaporation. As the liquid film flows downward, heat is transferred to it, causing the volatile components to vaporize. The vapors are then collected and condensed, while the remaining liquid is discharged from the bottom of the evaporator.
| 3. What are the advantages of using an agitated film evaporator? | |
Ans. Agitated film evaporators offer several advantages in chemical engineering processes. They provide high heat transfer rates due to the thin film formation, leading to efficient evaporation. The agitator helps prevent fouling and scaling on the vessel walls, ensuring continuous operation. Additionally, these evaporators are suitable for handling heat-sensitive materials and can operate at low pressure, reducing the risk of product degradation.
| 4. What applications can agitated film evaporators be used for? | |
Ans. Agitated film evaporators find applications in various industries. They are commonly used for concentration and purification of liquid products, such as fruit juices, pharmaceutical solutions, and chemical intermediates. These evaporators are also utilized in wastewater treatment processes, where they help separate and concentrate pollutants from the liquid stream.
| 5. How does an agitated film evaporator compare to other types of evaporators? | |
Ans. Agitated film evaporators offer distinct advantages compared to other types of evaporators. They have higher heat transfer coefficients and shorter residence times, leading to faster evaporation rates. The thin film formation in agitated film evaporators minimizes the risk of fouling and scaling, which can be problematic in other designs. Additionally, the ability to operate at low pressure makes them suitable for heat-sensitive materials, whereas other evaporators may require higher pressures.

we use agitated thin-film evaporators
for concentrating very viscous fluids
the feed is spread on the inside of the
cylindrical heating surface by the use
of wiper blades that rotate and
continuously scrape the inside surface
of the heating cylinder agitation
results in high convective heat transfer
coefficients which would otherwise not
be possible for these types of high
viscous liquids the cylindrical
configuration of this type of system
suggests that the heating surface area
would be rather low this means that this
type of system requires longer residence
time the processing capacity of these
types of systems would be low also the
maintenance costs are high due to moving
parts within the system
