Buss-SMS-CanzlerCore Competence High Viscosity Technology

Positive displacement discharge

Buss-SMS-Canzler is a leading inter-national supplier of thermal separa-tion solutions for difficult productsand mixtures. We are the world's lea-ding supplier of thin film evaporationtechnology. This is due to the long-standing experience and expertise ofthe four former companies Luwa,SMS, Buss and Canzler. This long ex-perience and expertise is now incor-porated into Buss-SMS-Canzler.

For our customers around the worldwe develop and manufacture machi-nes and plants for evaporation, pro-cessing of highly viscous materials,membrane filtration and drying. Ourexperience and our test centre allowus to develop customer specific pro-cess solutions by applying tailor-made equipment and completesystems.

Buss-SMS-Canzler partners you asconsultant, designer and manufactu-rer through all project stages: fromthe process layout, pilot tests, engi-neering, mechanical design, manu-facturing and documentation, toinstallation, start up and after salesservice.

High Viscosity Technology:Joint successBuss-SMS-Canzler supplies Thin FilmProcessors and Large Volume Proces-sors for your highly viscous products.As a special service, we offer our cus-tomers the joint development of com-plex applications with utilisation ofour comprehensive resources, such asrental units, test centre, process engi-neering and design department.

High Viscosity Technology at a Glance

Our High Viscosity Technology withThin Film Processors and Large Vo-lume Processors is utilised for the ther-mal treatment in polymer productionand in post-reaction treatment.

Typical processes are• Polymerisation• Polycondensation• Devolatilization, including the removal of monomers, solvents, and reactants from a variety of viscous products• Compounding/Reactive compounding• High viscosity mixing• Crystallization• Sublimation• Combinations of the above

Products includedin these processes are• Acrylic resins• Adhesives• Biopolymers• Chemical intermediates• Detergents• Elastomers• Engineered thermoplastics• Fibres• Foods including fruit purees, sugars and cheeses• High performance polymers• Phenolic resins• Polyesters• Resources recovery - waste volume reduction• Silicones• Styrene co-polymers

To achieve the best process solution,combinations with state-of-the-art tech-nologies such as flash evaporationand extrusion are made. Our owntechnologies comprise key equipmentwith integrated application tailoredproduct feed, discharge systems anddrives.

Thin Film Processors and Large Volume Processors:Economic Production for High Quality Products

low product hold-up allows the sepa-ration of large volatile rates in a sin-gle stage.

Large Volume ProcessorsThe Large Volume Processor programconsists of horizontally arranged, hea-ted reactors with either a single ortwin (co- or counterrotating) shaft wichprovide intensive mixing and knea-ding.

The highly versatile Large Volume Pro-cessors are characterised by large pro-cess volumes and self-cleaning. Theyallow for the efficient treatment of dif-ficult and/or phase changing products.

Large Volume Processors allow for theeconomic realisation of long resi-dence times and the combination ofvarious process steps in the same unit.

Thin Film ProcessorsThe FILMTRUDER® and VISCON® ThinFilm Processors produce a mechani-cally agitated thin product film whichis distributed over the inner surface ofa vertical heated cylinder by a rotor.The rotor continuously agitates thefilm, creating surface renewal and re-sulting in high heat flux and masstransfer. The rotor blades are desig-ned to propel the product down thecylinder walls. Volatile componentsare rapidly evaporated. The largefree vapour space in relation to the
