The wet product fed through the inlet nozzle is picked up by the rotor blades, applied on the hot wall and simultaneously conveyed towards the outlet nozzle at the opposite end of the body. The generated vapours are streaming counter-currently to the product flow and are leaving the dryer close to the feed nozzle. Evaporating and conveying capacity are adapted by the right rotor blade arrangement. Entrained particles from the dry zone are removed in the wet zone. Moisture levels of less than 1 % can be achieved. The residence time of the product is typically between 5 and 15 minutes. The outstanding heat transfer rate for hot solid products enables cooling of large amounts of solids in a compact machine compared to usually used cooling screws and without cooling air.In product melting like the melting of urea, the particles are heated up and molten inside the dryer. The melt can be mixed with other liquid and solid additives to improve the properties of the final products.

The vertical thin film dryer consists of a cylindrical, vertically arranged body with heating jacket and a rotor inside. The rotor is equipped with rows of pendulum blades all over the length of the dryer. The hinged blades spread the wet feed product in a thin product layer over the heated wall and mix the product layer material intensively. Therefore the volatile components evaporate continuously from the product layer with high evaporation rates. The hinged blades are designed with a minimum gap to prevent fouling of the heating surface by product, but are never in contact with the heated wall. The product enters the dryer at its top. The evaporation starts after heating to the boiling point. In the slurry zone first solids are formed and with advancing evaporation of the volatiles and continued shearing by the hinged blades the paste breaks up to powder. The final solid product is discharged by gravity at the bottom of the dryer via a suitable air lock.

Coating substrates is one of our core competences. We have been coating precision optic components with optically effective layers ever since 1948. Over the years, technical specifications and possibilities have radically changed. We now have several highvacuum plants, an ultrasound cleaning and drying plant at our disposal to treat the substrates. We also build our own equipment e.g. for asymmetrical prisms. Coated substrates are inspected and documented with a "Lambda 900" PE spectral photometer. Antireflection coatings

SMS offers sludge drying systems with horizontal thin film dryers for treatment of sludge from municipal as well as from industrial waste water treatment plants. Variations of this sludge treatment process are: Pre-drying up to 35 to 50 % dry solid content before incineration in fluidized bed incinerators 65 to 75 % dry solid content before combined incineration with garbage, composting or landfill Full drying up to 85 to 95 % before thermal utilization as bio-fuel for cement kilns, coal fired power stations, pyrolysis, gasification or other conversion processes before composting and agricultural usage as fertilizer and for soil reclamation In all these drying processes the thin film dryer is the first choice.

The new LUXOR swift 250 dry air generator offers the ideal price-performance ratio for standard applications in the drying of granulate. The LUXOR swift 250 has a dry air capacity of 250 m³/h. The dry air generator can either be operated with a single drying bin or combined with multiple preconfigured drying bins in your plant. The drying bins are available from 100l to 900l sizes. This gives you the maximum possible flexibility and an uninterrupted production flow. For more energy efficient drying, additional functions such as dew point control or return air cooling can be added. Versatile use Different drying bin sizes for different applications Thanks to motan’s automatic air regulation the drying process can be optimized. Different sizes of drying bins with integrated heating allow a wide range of applications with proven motan drying technology.
