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.

Transport and disposal costs, at over 70 percent, represent by far the largest cost item in sludge dewatering. A powerful dewatering assembly is thus an important criterion. With a Flottweg HTS Decanter in the C series, you can achieve the highest possible total dry solids in the dewatered sludge, thereby continuously saving on transport and disposal. More than 50 years of experience in the dewatering of sewage sludge and continuous further development have gone into the design of the Flottweg HTS Decanter. This experience, combined with references from the entire world, makes Flottweg one of the leading providers of mechanical separation technology. The HTS Decanter is attractive for its performance, its efficiency, and its high cost-effectiveness. The decanters in the Flottweg C series cover a throughput range from about 5 to over 150 cubic meters per hour. We can offer you comprehensive know-how and customized systems.

The sample drill for stalk material is a sampler especially for hay, silage, straw, herbs, bushes or other stalky plant dry material where other drills quickly get tangled. The special geometry of the drill tip cuts effectively and quickly into different stalky materials. The hay and silage sample drill takes samples quickly, cleanly and easily from a silo or bale. Sampling with mechanical assistance from a drill or powerful cordless screwdriver allows the sample to be taken effortlessly with little manual effort. The sample drill can be used flexibly both horizontally (sampling from the side) and vertically (sampling from above). The robust and durable tube drill is completely made of stainless steel 1.4404/1.4034 (316L/420) or aluminium/stainless steel 1.4034 (420). The practical ejector helps to empty the sample from the sample drill.

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.

VENTAPP radial fans are used in wood-processing plants where air or loaded air is conveyed under increased pressure. They convey gases, bres, and particles; they are used for wetting, drying or ltering of media. In energy plants, in bre drying, for mat formers and dust extraction systems they form integral parts of Siempelkamp plants. Features Pressures beyond 20,000 Pa Temperatures up to 700 °C Impeller wheel diameters up to 3,150 mm Circumferential speed up to 200 m/s Gas-tight and pressure-resistant design ATEX Advantages High eciency Smooth operation Robust design Low caking, high wear resistance High dependability and operational safety Diverse accessories Maintenance and repair service Variants Drive type Casing positioning Size of all components Angular position Material Colour

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.
