1. High Performance per unit surface area
2. Specialized Scraper Blade Design for Soft Silent Operations
3. Custom Scraper design for enhanced equipment shelf life
Types of ATFD designs:
1. Steam operated ATFD
2. Thermic fluid based ATFD
What Is an Agitated Thin Film Dryer?
A highly dependable solution for the use of an Agitated Thin Film Dryer (ATFD) is provided in industries where heat-sensitive, viscous, or sticky substances have to be dried effectively. An Agitated Thin Film Dryer is a continuous dryer that is used in evaporating solvents or moisture in liquids, slurries, and pastes by spreading them out over a hot surface in a thin layer. Being an outstanding Agitated Thin Film Dryer Manufacturer in Indore, Distington Engineers and Consultants have provided state-of-the-art ATFD systems that are designed to perform efficiently, evenly, and last long in industrial applications.
The ATFD technology finds extensive application in the pharmaceutical, chemical, food, and effluent treatment processes in which accurate temperature regulation and low residence time are essential.
Agitated Thin Film Dryer Working Principle
An agitated thin film dryer works on the principle of thin film evaporation with mechanical agitation. The feed material is introduced at the top of the vertical cylindrical drying chamber. A rotor with blades is mounted and spins at a high rate to disperse the feed into a thin, uniform film all over the heated inner wall of the dryer.
As the film descends, the heat is given out of the jacketed wall and the moisture or the solvent is rapidly evaporated off. The rotating blades maintain the film continuously and avoid fouling, as well as improve the heat transfer efficiency. The vapours are still gathered at the apex of the chamber, and the product, which has been dried, is thrown off at the base.
This process ensures:
- Very short residence time
- Uniform heat exposure
- Limited thermal degradation
Effective management of sticky and heat-sensitive substances.
Key Components of ATFD
There are a number of important components of a high-performance agitated thin film dryer:
Vertical jacketed heating surface drying chamber
Rotor assembly having the specially designed blades to form the film.
Material entry feed distribution system.
Use of steam, hot oil, or electrical heating to heat the system.
Solvent recovery, vapor outlet, and condenser.
Continuous discharge system of products.
Internal agitation by means of a drive with speed control.
Distington is quite a professional Agitated Thin Film Dryer Manufacturer; therefore, every part is designed to last a long period, transfer heat efficiently, and perform effectively.
Advantages of ATFD
Agitated thin film dryers have a number of technical and operational benefits:
- Strong evaporation factor and even drying.
- Very short residence time, which is good with heat-sensitive products.
- Constant production and consistent quality of output.
- Good work with sticky, oily, and foul substances.
- Little product degradation and discoloration.
- Small-scale design and high throughput.
- Cleaning and maintenance are easy.
Such benefits render the ATFD systems better than traditional batch dryers in challenging industrial use.
Applications of Agitated Thin Film Dryers
The agitated thin film dryers find application in:
- Manufacturing of pharmaceuticals and API.
- Specialty and chemical industries.
- Nutraceutical processing/food.
- Manufacture of polymer and resin.
- Sludge drying and effluent treatment.
- Solvent recovery systems
- Product concentration sensitivity to heat.
They work especially well with very viscous, thermally sensitive or fouling traditional dryers.
