Definitions

  • the invention relates to a method and a device for cleaning tableting, coating and granulating machines, in particular rotary tablet presses, with a treatment chamber that includes at least the rotor.
  • the invention is therefore based on the object of providing a method and a device for cleaning tableting, coating and granulating machines, in particular a rotary tablet press, with complete removal of the liquid residues from and from the treatment chamber with little use of cleaning liquids in this component, in particular a rotary tablet press, is ensured.
  • the method according to the invention provides that a cleaning agent and a rinsing agent are sprayed and sucked off again one after the other within the treatment chamber, then all openings of the treatment chamber are closed and a vacuum, in particular from about 0.1 to 0.2 bar , is generated within the encapsulated treatment chamber.
  • the device according to the invention provides that spray heads for spraying the cleaning and rinsing agent are provided within the treatment chamber and connections are provided for suctioning off the cleaning and rinsing agent and that devices for closing all openings of the treatment chamber and a vacuum device which can be connected to them are provided in order to prevent the Negative pressure of about 0.1 to 0.2 bar from the absolute pressure within the encapsulated treatment chamber.
  • the method and the device according to the invention enable cleaning, in particular the components of the rotor of a rotary tablet press located in the treatment chamber, with little use of detergents and dishwashing agents and complete removal of the detergents and dishwashing agents used by applying the negative pressure of approximately 0.1 to 0.2 bar of the absolute pressure within the encapsulated treatment chamber.
  • the generation of the vacuum within the treatment chamber enables the components of the rotary tablet press located within the treatment chamber to dry, even in inaccessible openings and parting lines of the rotor. Remaining liquid residues are sucked off by means of the vacuum and drawn off via the vacuum connection.
  • the method according to the invention is then followed explained in more detail with reference to the device according to the invention shown in the drawing.
  • the single figure shows a side view of a rotary tablet press with a rotor located within the treatment chamber, certain components having been removed beforehand.
  • the rotary tablet press comprises a machine base 1 standing on feet 2 for receiving the bearing and the drive elements of the rotor 3, which is arranged within a treatment chamber 4 arranged above the machine base 1 and is provided with a further bearing in the head piece 5.
  • the treatment chamber 4 is enclosed by four window panes 6, which enclose the rotor 3 and are fixed to four supports 7 which mount the head piece 5 on the machine base 1.
  • the machine base 1 comprises a cover plate 8, not shown in detail, the surface of which each has a gradient of 3 to 4 ° to outlets, to which suction hoses 9 are connected, which are guided to a common drain connector 10.
  • a plurality of high-pressure spray nozzles 11 are arranged inside the treatment chamber 4 and are directed against the rotor 3 and into the interior of the treatment chamber 4 at different angles of inclination from above and below.
  • an inflow nozzle 12 for cleaning and rinsing agents and an inflow nozzle 13 for superheated steam are attached, which lead via channels (not shown) in the head piece 5 into the treatment chamber 4, in which the rotor 3 is mounted.
  • a connecting piece 14 is attached to the machine base 1, which is connected to the vacuum hose 15 with the Treatment chamber 4 is connected and to which a vacuum device, not shown, for applying a vacuum of 0.1 to 0.2 bar within the treatment chamber 4 can be connected.
  • the treatment chamber 4 and the rotor 3 rotating slowly therein are rinsed, a rinsing agent, in particular distilled water, being fed in via the inlet connection 12 and sprayed against the rotor 3 via the high-pressure spray nozzles 11.
  • a rinsing agent in particular distilled water
  • the detergent is then also sucked off again via the suction nozzle 10 and can be cleaned via filters and used again.
  • all openings of the treatment chamber 4 are hermetically sealed, in particular the suction nozzle 10, the inlet nozzle 12 for cleaning and washing-up liquid and also the inlet nozzle 13 for superheated steam and the outlet nozzle 10.
  • the window panes 6, the cover plate 8 of the machine base 1 and the base plate of the head piece 5 enclose the hermetically sealed treatment chamber 4.
  • a negative pressure of about 0.1 to 0.2 bar is then generated based on the absolute pressure within the then hermetically sealed treatment chamber 4, so that the entire still within the Treatment chamber 4 residual moisture adhering to the window panes 6 and in particular the residual moisture remaining within the bores and connecting gaps of the rotor 3 are completely removed.
  • the residual water evaporates at room temperature and is drawn off via the connecting piece 24 for the vacuum device.
  • the first and the second cleaning step are preferably carried out at temperatures above room temperature, in particular at temperatures between 40 and 70 ° C. This prevents condensation from forming when the treatment chamber 4 is opened.
  • the process enables compliance with the clean room conditions for the production of food and beverages according to GMP and FDA regulations.
  • the high-pressure spray nozzles 11 can also be designed as E-shaped spray heads, a high-pressure spray nozzle being arranged at the ends of the horizontal webs of the E-shaped spray heads, which, for example, enclose the die table 18 on both sides and spray directly into the holes in the die.
