Mechanically Agitated Thin Film Dryer is an indirectly heated continuous dryer. The feed can be in the form of a solution, slurry, wet cake or paste. If required it operates under vacuum. We offer both vertical and horizontal versions.   How they work : The vertical Agitated Thin Film Dryer has a jacketed cylinder with a closely fitting rotor at the centre. During operation the rotor revolves at high speed. The feed distributor spreads the incoming feed uniformly over the cylinder top periphery. The rotor blades pick up the material, spread it over heated surface in a thin film and agitate the film intensely, as it rapidly travels down. The material transforms from solution to slurry, wet cake, wet powder and finally dry powder as it travels from top to bottom. The vapour generated rises counter-currently to the inbuilt entrainment separator. Here the entrained droplets are separated from the vapour stream. The clean vapour leaves the dryer through the vapour nozzle at top. The horizontal version of the dryer is used for drying of wet cake, pastes, wet powders. The wet feed enters at one end and dry powder leaves from the opposite end. The vapours move counter currently to the powder flow and leave through vapour nozzle.

Features :

Once step drying eliminates number of steps like pre- concentration, filtration or centrifugation   Feeds can be processed without pre-concentration or dilution Indirect heating and drying in absence of air. Particularly effective for heat, light and oxygen sensitive products. Best suited for solvent bearing products for complete solvent recovery Quick processing time, best suitable for heat sensitive products Probably the most energy efficient dryer in the market. Thermal efficiency exceeds 90% Fine powder of uniform consistency can eliminate pulverizer from downstream step Intense agitation suppresses fouling, keeps heat transfer surface clean Operating pressure under vacuum, up to 1 torr Excellent turn down capability Low product holdup, ideal for hazardous applications Different rotor configurations to suit variety of applications

Applications :

Drying APIs, bulk drugs and intermediates Dyes, pigments and intermediates Organic and inorganic salts Recoveries Solvent and products from thick dry residues DMSO from salt bearing organic residues Glycerine from salt bearing organic residues Water from organic and salt bearing waste water streams

 

Techno Force Solutions was started in 1990 to manufacture process equipment based on Thin-Film technology, mainly Evaporators, Dryers and high vacuum Short Path Distillation Units. A pilot plant (test center) was also started simultaneously. The Extractors, Scraped Surface Heat Exchanger and Waste Water-Zero Discharge Systems were added subsequently to the product range in response to the demand from customers.
