The main component of the Combi Fluidization Technology is the CFT dryer. This dryer is filled with dry product, which is fluidized by the rotor. The wet product is fed into the hot fluid bed and due to the movement of the bed it is evenly distributed throughout the dry product and dried efficiently. The formation of sticky/viscous phases, the direct contact of the wet feed with the heat exchange surface and the consequential formation of crusts are avoided to a large extent. The whole process is comparable to conventional drying with external reflux system, but with the Combi Fluidization Technology the external mechanical work is no longer necessary. The vapour cleaning is integrated into the drying room of the CFT dryer, so that the vapours can be easily processed in a condenser or rectifier. This technology can be used for many different applications, as various heating methods are available and temperatures up to approx. 600°C can be reached. The CFT dryer can be operated under vacuum or overpressure. This technology can be used for many different applications, as various heating methods are available and temperatures up to approx. 600°C can be reached. The CFT dryer can be operated under vacuum or overpressure. Many of the slurries and sludges occurring in the field of environmental protection, as e. g. paint and varnish sludges, can be processed under atmospheric pressure. The Combi Fluidization Technology also offers a very interesting alternative with regard to cost and energy demand compared to the spray drying of products with sticky phases, if no specific properties and conditions of the dry product are required.
Buss-SMS-Canzler is a leading international supplier of thermal separation solutions for difficult products and mixtures. We are the world’s leading supplier of thin film evaporation technology, this is due to the long-standing experience of the three former companies Luwa, SMS, Buss and Canzler. This long experience and expertise is now incorporated into Buss-SMS-Canzler. For our customers around the world we develop and manufacture machines and plants for evaporation, processing of highly viscous materials, membrane filtration and drying. Our experience and our test centre allow us to develop customer specific process solutions by applying tailor-made equipment and complete systems. Buss-SMS-Canzler partners you as consultant, designer and manufacturer through all project stages: from process layout, pilot tests, engineering, mechanical design, manufacturing and documentation, to installation, start up and after sales service.
For more than 50 years we have supplied different types of dryers, adapted to a large variety of applications throughout the world, currently more than 500 dryers. Based on our longstanding experience and supported by lab and pilot tests, the specialists at Buss-SMS-Canzler select the most suitable drying technology for your application. Lab tests in our lab equipment show general feasibility. Tests in our pilot plants provide the basis for the design of our dryers. These studies are not only carried out upon our customers’ request, but also to investigate new applications on our own development projects, as for example the TDI recovery in the CFT dryer.
The Buss-SMS-Canzler range of dryers carries out the following process steps: drying, cooling, heating, calcining, reacting, mixing, sublimation and sterilisation. The product range covers heating temperatures of -20°C to 400°C, process pressures of 0,01 to 30 bar and residence times from seconds up to several hours. Buss-SMS-Canzler offers a program of dryers using different operating principles tailored to meet the individual process requirements when treating products with particular characteristics and specific drying behaviour. Vertical and horizontal thin film dryers with thin product layers on the heat exchange surface, the ROVACTOR®
with specific paddles to convey lumpy wet feed, the REACTOTHERM® with self-cleaning hooks for sticky products as well as the CFT dryer with its mechanically agitated fluid bed are technically mature solutions for a large variety of different drying applications.
