Overview
Agitated thin film evaporators are often employed for fluids with high viscosity and sensitivity that is complex to tackle. Impediments with complicated materials are successfully handled by agitated thin-firm evaporation. The process uses mechanical agitation of the moving substance film under regulated conditions and indirect heat transfer to swiftly segregate the volatile from the less volatile components.The separation is usually done under a vacuum to maximize the difference in temperature while retaining the most suitable product temperature and to enhance volatile stripping and recovery.
An evaporator like this has two main parts: a rotor that spins at a high speed inside the shell and a jacketed shell. At the upper edge of the framework, the feed is introduced. The distributor distributes along with the shells that are tangential to it. The rotor blades stir the feed and disseminate it uniformly across the hot surface creating a thin coating. The heat source going through the jacket evaporates the volatile ingredient in the feed. Prior to exiting through the vapor nozzle, the flow counter is emptied inside an entrainment separator. The concentration product is dispensed at the bottom.
Working Principle
ATFE refers to the evaporation of a liquid to produce flakes or dry powder from a concentrated liquid. The ATFE is the optimum machine for converting condensed material into solid samples in a constant cycle. ATFE is made up of a vertical and cylindrical body with a thermal jacket and a rotor within the shell containing rows of pendulum blades all way down the dryer's length. The liquid feed product was distributed in a thin film across the heated wall by the hinged blades. The heat then transfers from the jacket towards the principal shell underneath the streamlined agitation. The turbulence enhances as the object goes through the release prior to accessing the calming zone located behind the blades. The liquid will evaporate as well as the liquid would then transform to cake, slurry, flex, or dry powder. The vapours generated ascend upwards, counter - current to the liquid, and travel through the ATFE's vapor outlet's Cyclone separator. These vapours will then be condensed and collected as residue in a condenser. For temperature - sensitive items, the equipment will be maintained under vacuum, and for standard drying, it would be operated under atmospheric conditions.
The applications for ATFE systems:
- Pharmaceutical Industries
- Textile Industries
