An agitated thin film dryer is a type of drying equipment used in industrial processes to remove moisture from liquid or slurry-like materials. It consists of a cylindrical vessel with a heating jacket and an agitator inside, which facilitates the formation of a thin film of the material on the vessel’s walls, allowing for efficient drying.
The material to be dried is fed into the vessel and comes into contact with the heated surface of the vessel’s walls. The agitator inside the vessel rotates, spreading the material as a thin film on the walls, exposing a large surface area to the heated surface, promoting rapid evaporation of the moisture. The agitator also helps to prevent the material from sticking to the walls and forming a solid cake, ensuring continuous and efficient drying.
The agitated thin film dryer operates under vacuum or reduced pressure conditions, which lowers the boiling point of the moisture, allowing for gentle drying at lower temperatures, which is suitable for heat-sensitive materials. The evaporated moisture is then condensed and collected separately from the dried material.
Agitated thin film dryers are commonly used in industries such as chemicals, pharmaceuticals, food and beverage, and petrochemicals for drying applications such as solvent recovery, crystallization, and production of powders or granules. They are known for their high drying rates, short residence times, and ability to handle heat-sensitive materials without degradation. However, proper control of operating parameters such as temperature, pressure, and agitator speed is critical to achieve optimal drying performance and prevent issues such as product degradation or fouling.
Design is the safest way to update values. This is due to highest specification.
High Operating Efficiency
Shell side baffles enabled a high level of operational efficiency while also allowing for manageable reductions in fluid pressure.
The Next Generation of Evaporators
A highly experienced team of mechanical, process, and thermal design experts collaborated to optimise each and every aspect of Evaporators designs for the next generation design.
ATFDs are used for drying and evaporating various chemicals, such as solvents, polymers, resins, and dyes, in the chemical industry. They are also used for concentrating and drying heat-sensitive chemicals that require gentle treatment to avoid degradation.
ATFDs are used for drying food products, such as dairy powders, starches, proteins, and flavorings. They are ideal for heat-sensitive food products that require gentle drying at low temperatures to retain their nutritional value, flavor, and aroma.
ATFDs are used for drying pharmaceutical products, such as antibiotics, vitamins, and herbal extracts. They are commonly used in the production of pharmaceutical powders and granules, as well as for drying and concentrating liquid pharmaceutical formulations.
ATFDs are used for drying and concentrating bio-based products, such as enzymes, fermentation products, and biofuels. They are also used for processing bio-based feedstocks and for producing bio-based chemicals and pharmaceuticals.
ATFDs are used for drying and concentrating energy-related products, such as biofuels, bio-oils, and biodiesels. They are commonly used for removing moisture from bio-based energy products and for producing dry powders and granules that are suitable for further processing or combustion.
ATFDs are used for drying and concentrating nanoparticles and nanostructured materials in the field of nanotechnology. They are commonly used for producing dry nanopowders with controlled particle size and morphology, as well as for producing nanocomposites and nanomaterials with enhanced properties.
