A thin film dryer (TFD) has two major assemblies – jacketed shell and rotor assembly having closely fitting hinged blades which rotate inside the shell.

ATFD represents evaporation of water/solvents to make concentrated fluid to dry powder or pieces. This precisely Agitated Thin Film Dryer has made it conceivable to dry items with complete dissolvable recuperation. This indirectly warmed dryer, with no air contact made the drying conceivable with preparation time of a few moments, a perfect component for heat drying items.
ATFD is the perfect mechanical assembly for consistent preparation of concentrated material to dry solids. A thin film dryer (TFD) has two significant gatherings – jacketed shell and rotor get together having intently fitting pivoted blades which turn inside the shell. It is the most energy effective dryer in the market with warm effectiveness surpassing 90%.It is an incredible apparatus for getting the dry powder from nourishes in solution, slurry, wet cake or glue structure.

An Agitated thin Film Dryer contains a centrally set rotor having closely fitting blades. It rotates in a very precision-machined jacketed shell that can be the most energy efficient dryer within the market. The feed is regenerated into a thin film that is extremely agitated as a result of action of the high-speed rotor. The feed material goes through phases of suspension, paste and wet powder, before initiating as a dry powder. The dry powder solids at the bottom of the dryer are collected in the receiver. The feed material goes through different phases of slurry, paste, wet powder and finally comes out as a dry powder.

Agitated Thin Film Dryer Manufacturer comprises a cylindrical and vertical body with warming coat and a rotor within the shell which is outfitted with columns and pendulum cutting edges everywhere throughout the length of the dryer. The hinged sharp blades spread the wet feed item in a far film over the warmed divider. The feed enters the dryer digressively and gets appropriated similarly along the inside surface of the shell as thin film. The pivoted rotor edges hold the film under extraordinary tumult forestalling any scale arrangement. Warming medium going through the coat vanishes unstable segments in feed. The fume created a stream counter presently to bolster and leave through fume spout at the top of the dryer. The dry powder solids at the base of the dryer are gathered in the collector. The feed material experiences a distinctive period of slurry, paste, wet powder lastly turns out as a dry powder.
Features

Residence time of a few seconds eliminates degradation of heat sensitive product.
Drying in absence of air with indirect heating, hence effective for light and oxygen sensitive products.
Complete solvent recovery is possible since no air is used for drying as in case of all direct (air) contact dryers.
Operating pressure can be as low as 1 mbar Thermal efficiency of more than 85%, hence low operating loss compared to other dryers.
Fine powder of uniform consistency eliminates use of pulverizer for grinding in downstream steps. Amorphous powder can be obtained.
Different rotor designs available for process & effluent drying.
Applications

Drying of bulk drugs, intermediates, dyes, pigments, organic & inorganic salts.
Drying of an effluent stream to get zero discharge.
Recovery of solvents like DMF, DMSO & Glycerin from salt.
