They have a mixing container which is provided with a mixing device, for example an agitator and / or dissolver and / or homogenizer, propeller or the like for mixing products.
  • a mixing device for example an agitator and / or dissolver and / or homogenizer, propeller or the like for mixing products.
  • the mixing container known from the publication has a flow refracting device which is referred to in the publication as an active baffle and which has a drive.
  • the flow-breaking device can also be designed completely or at least partially as a passive flow-breaking device without its own drive be and have, for example, a fixedly installed in the mixing vessel Strömungsbrechungsêt whose purpose is to disturb the example caused by a mixer flow, in particular to avoid thrombus formation or the like and at the same time redirect the flow to improve the mixing, or the flow direction change.
  • the cleaning of a corresponding mixing container is carried out in a CIP ("Cleaning in Place") cleaning method, in which the inner surfaces to be cleaned are cleaned without dismantling the mixing container.
  • CIP Cosmetic in Place
  • spray heads are used, which are permanently installed in the mixing container.
  • the disadvantage here is that a arranged in the mixing vessel flow baffle generates a spray shadow, so that there is a risk that the inner surfaces of the mixing container in the spray shadow not or at least not sufficiently cleaned.
  • the use of additional spray heads to avoid or reduce a spray shadow requires additional equipment and additional piping and additional nozzles or passages in the mixing vessel, which must be constructed frequently and even usually as a pressure vessel.
  • the invention has for its object to provide a mixing container referred to in the preamble of claim 1 type of apparatus for mixing flowable, especially liquid or pasty substances, in which, with relatively little expenditure on equipment, a reliable CIP cleaning of the interior of the mixing container is made possible.
  • the basic idea of the invention is to configure the flow-disrupting device such that at least one outlet opening for cleaning fluid for cleaning the inner wall of the mixing container is provided on the flow-refracting device.

  • the flow-breaking device then simultaneously forms a supply line for the cleaning fluid, so that additional piping is eliminated and in this way compared to mixing vessels, in which additional piping is required for the purpose mentioned, the equipment cost is reduced.
  • nozzles and passages are saved in the mixing container.
  • a particular advantage of the mixing container according to the invention is that a spray shadow when spraying the inner wall of the mixing container with cleaning liquid can be completely avoided.
  • at least one outlet opening for the cleaning liquid can be formed in a section of the flow-breaking device, for example the flow-disrupting body, which is directly opposite the inner wall of the container. With such an arrangement of the outlet opening, the inner wall of the container is thus sprayed directly, without there being an obstacle between the outlet opening and the inner wall.
  • a flow-breaking body of the flow-breaking device is installed from a lid or bottom of the mixing container, the flow-breaking body is held by the lid or the bottom, so that a separate connecting element for connecting the flow-breaking body to the wall of the mixing container is basically unnecessary.

  • the flow-restricting body or the connecting element delimits the feed channel, so that separate pipelines for supplying the cleaning liquid to the outlet opening or the outlet openings are unnecessary.
  • the mixing container is simplified in its construction.
  • An advantageous development of the aforementioned embodiment provides at least two outlet openings communicating with the feed channel.
  • at least two outlet openings are fed via a common feed channel.
  • the number of outlet openings and their arrangement on the Strömungsbrechungsève or the connecting element can be selected according to the respective requirements within wide limits.
