  Process advantages
VG wet granulation is an important technology for the manufacture of granules, pellets and tablets. Granules from vertical granulators (also forced, moist or wet blenders) are distinguished by a compact structure with good flow characteristics, as the product is mechanically compressed during the process.



Principle of operation
For this process, Glatt offers Vertical Granulators with batch sizes from 10
0g to 1t/batch.
The technical design of the process has a significant effect on the properties of the end product. In the Wet Granulation process, powder is presented in a vertical granulator and subsequently moistened or sprayed with molten material. The shear forces produced by the Z-shaped rotor blades lead to an intensive mixing of the powder and, with the addition of binder solutions, to the rapid formation of high-density granulates. The chopper on the side wall of the container assists the formation of larger agglomerates.
Single Pot process:
With smaller batch sizes (up to 80
0l) and/or frequently changing products, granules can also be dried and cooled in the vertical granulator. The major advantages lie in the gentle product handling in vacuum up to 10mbar and the comparitively small processing area, which can be cleaned very quickly and easily.


In systems using the Single Pot method, the container is designed with a double wall and can be connected to a solvent separator system. Additional gas-stripping by means of nozzles in the lee of the rotor blades considerably accelerates the drying of the particles.
