ABSTRACT:
A process for cleaning tabletting, pan-coating and granulating machines, especially rotary tabletting presses, with a treatment chamber including at least the rotor. To ensure the complete removal of the liquid residues from the treatment chamber and from the components left in the treatment chamber, especially of the rotor of a rotary tabletting press using small amounts of cleaning and rinsing liquids, a cleaning agent and a rinsing agent are sprayed within the treatment chamber and then drained off. All openings of the treatment chamber are then closed, and a vacuum of about 0.1 to 0.2 bar (absolute pressure) is generated within the sealed treatment chamber. The vacuum drains the residual liquid from all holes and joints of the rotor and from the treatment chamber.
