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.

This group of polyurethane products typically features a lightweight foam core with a compact, dense skin – the so-called integral skin. Thanks to these properties, PU soft- / semi-rigid integral skin foams cover a broad range of applications such as steering wheels, shifter knobs, arm rests, protective pads, floor mats and operating room rests. Typical properties Moulded part density of 220–600 kg/m³ Shore A hardness of 10–90 Available foaming agents: pentane, hydrofluorocarbons (such as 365/227mfc) and water Good abrasion resistance Special formulations and versions Viscoelastic Anti-static Flame protection formulations Automotive: FMVSS 302 Rail vehicle construction: DIN 5510 (S4, SR2, ST2), EU TL 45545 Aircraft construction: ABD 0031, FAR 25.853 Construction industry: DIN 4102 B2 Recreation industry: M2, UNI 9175/87 (= CSE 4/83): class 1.IM, BS 5852 crib 5
