Agitated Thin Film Dryer Dealers

The Agitated Thin Film Dryer consists of a jacketed vertical cylinder withmulti-blade rotors at the centre. With rotor revolving at high speed, material is spreadover the jacketed surface in a thin film due to the centrifugal force. The film is agitated intensely as it travels down the cylindrical vessel rapidly. With the material traveling from top to the bottom it undergoes physical changes from solution to slurry, wet cake, wet powder and then dry powder as the final product. The vapour produced during the process travels upwards towards the entrainment separator,where the entrained droplets are separated from the vapour and the clean vapour is removed from the ATFD through a nozzle from the top.

Due to its inherent design features, it is ideal for thermal treatment of solutions and heat sensitive products, where reduced operating temperatures and vacuum operating pressures are desirable. The typical Agitated Thin Film Evaporator consists of a tubular heat transfer area with an external heating jacket and a fast-revolving, inner rotor with flexible or rigid wiper elements. The driving speed is adapted to the product being handled, its particular specifications and task. The feed product is evenly distributed by the rotor and its wipers over the heating surface, forming a thin liquid film of uniform thickness. Highly turbulent swirls are produced at the tip of the rotor blades and wipers with intensive mixing and agitation of the product, as it comes into contact with the heating surface. This assures excellent heat transfer combined with constant renewal of the product film and provides an even heating and short residence time of the product through the heated zone.   Key Advantages Good heat conductivity (k-value), even when working with highly viscous and contaminated products Minimal thermal stress, thanks to low operating capacity, therefore a short dwell time (10-20 seconds of mean dwell time) No dead zone, therefore overheating prevented and perpetual high product quality guaranteed Continuous mechanical cleaning of the heating surface prevents incrustations High evaporation rates, due to highly turbulent film and large difference in temperature Gentle evaporation, due to short residence times, rapid conveyance in the heated zone and the constant product film renewal, happens often Combined with suppressed boiling points due to operation under vacuum Reduced need for maintenance because of sophisticated bearings and shaft sealing parts Shorter downtime and assembly time for maintenance and inspection No corrosion as outside surface is usually made of stainless steel Evaporation in one pass, no circulation Small film thickness, no hydrostatic height High turndown ratio and high flexibility for variation in requirements Low operating pressure down to 1 micron to reduced boiling temperature Single step drying because of unique designed combination of vertical and horizontal dryers Effective evaporation of concentrated slurries, heat sensitive products, viscous and fouling fluids up to 99% in a single pass Simple installation as the equipment is supplied skid mounted with all inter connecting piping, condensers and vacuum system Single source responsibility for all project stages because of combined expertise in vacuum technology, heat transfer, evaporation, crystallization and drying – a design mix which gives optimal results   Applications Mainly used for difficult vaporization and heat exchange processes, especially where products to be handled are highly viscous and conventional plants can no longer meet user demands because heat transfer is insufficient. Due to the liquid film, mechanically generated on the heating surfaces, thin film equipment achieve much better heat transfer rates, even with highly viscous products containing solids. To concentrate highly viscous products, polluted liquids, salt solutions, oils, resins, etc As a sump evaporator for vacuum rectification columns Sludge drainage To continuously dry powdery residues Distillation of high-boiling substances under high vacuum Degassing and/or removal of volatile components of highly viscous products Heating or cooling of viscous solutions Improve product quality by removing colour bodies, minimizing impurities and eliminating thermal degradation Increase product recovery by reclaiming additional bottoms product from overhead and distillate products from bottoms Separation of close-boiling compounds Enhance product recovery Recovers additional bottoms product from overhead

Since their introduction more than 50 years ago by Luwa and Samesreuther, today KEP Engineering is manufacturing Thin film Evaporator, generally called as Agitated thin film dryer. Specifications : Operating pressure from atmosphere down to 1 Ton vacuum Operating temperature up to 300 oC Advantages : Suitable to high vacuum distillation with very low residence time. Narrow spread Avoid product re-circulation and possible degradation Apt for viscous products Ideal for hazardous applications Applications : Vacuum Distillation Drying Solvent Recovery Concentration of bulk drugs, enzymes, juice, milk product etc. Features v Agitated thin Film Evaporator differ in the following main technical features from other evaporator types: Continuous and trouble-free processing of viscous, fouling and contaminated fluids by high turbulence in the liquid film, which also reduces the required temperature difference across the heating surface; v Gentle product treatment because of the short residence time and the narrow residence time spectrum in the whole equipment; v High evaporation performance because of high surface heat flux; v High evaporation ratio in a single pass; v Minimum losses in case of product change because of the low hold-up.

We are offering agitated thin film dryer. 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.

Agitated Thin Film Dryer is consist of cylindrical, vertical body with heating jacket and a rotor inside of the shell which is equipped with rows and pendulum blades all over the length of the dryer. The hinged blades spread the wet feed product in a thin film over the heated wall.
