The great advantages of the vertical granulator are the gentle drying of the product in a vacuum of up to 10 mbar and the relatively small process space, which is quickly and easily cleaned. An additional air supply via nozzles at the rotor blades significantly accelerates the drying of the particles. The Glatt vertical granulators are available which can be easily integrated into a vertical or horizontal process chain. Loading of the vertical pelletizer can be carried out by means of containers with lifting and conveying devices as well as loading devices or pneumatically by means of vacuum feed systems. Pellets are discharged from the working chamber either by gravity or by means of a vacuum system into a fluidized bed unit or into a container. OYSTAR Huttlin high shear mixer-granulators.

To carry out the mixing process, this unit has an innovative mixing device, which achieves a completely new mixing character. The disadvantage of most conventional stirring mechanisms is their geometry, which results in poor mixing of the product at low speeds. In addition, there are many parts of the chamber where the product can stick to the walls and thus fall out of the granulation process and subsequent drying. This innovative design, however, ensures excellent, thorough mixing of the product even at low blade speeds. At the same time, the central cone, the device that provides the gas supply for barbotage, prevents sticking on the walls and the formation of dead zones in the working chamber. As for the pelletizing process, this equipment produces the highest quality pellets thanks to the quality and controlled product mixing and homogeneous atomization of the liquid.
