They are aligned in particular at an angle greater than 0° and less than 90° to the axial direction and at an angle greater than 0° and less than 90° to the radial direction of the line opening.
  • the number of nozzle openings is in particular greater than two, in particular greater than three.
  • the at least one cleaning liquid supply line is in particular a ring line, which is in particular ring-shaped in the nozzle body.
  • the cleaning liquid supply line can also form, for example, only one ring segment, ie a ring section, ie be interrupted at at least one point in the nozzle body and thus have two end regions in the nozzle body.
  • cleaning liquid supply lines can be formed in the nozzle body, which each extend, for example, over a partial region of a circumference of the nozzle body and thus each form a ring segment, ie a Ring section, wherein the respective cleaning liquid supply line is then closed, for example, from adjacent cleaning liquid supply lines formed in the nozzle body, ie the ring segments or ring sections are then not connected to one another.
  • the cleaning unit according to the invention can be installed in the line before or after the valve to be cleaned, depending on which side of the valve is to be cleaned. If both sides of the valve are to be cleaned, one of the cleaning units can also be installed on each side of the valve.
  • a valve arrangement thus has the valve arranged or arrangeable in the line and the cleaning unit or such a cleaning unit on each side of the valve.
  • the cleaning unit or the respective cleaning unit is thus arranged in the axial direction of a valve opening of the valve on one of the two sides of the valve.
  • the nozzle openings of the cleaning unit are each aligned in the direction of the valve, in particular in the direction of a closure element of the valve when this is arranged in a closed position, i.e. in a closed valve state.
  • the nozzle openings are aligned in such a way that they jointly, at least substantially, spray the entire side, in particular the surface, of the closure element facing them with cleaning fluid.
  • the cleaning unit according to the invention and the valve arrangement according to the invention are particularly advantageous for use in connection with a cleaning device for cleaning the interior of a hollow body with cleaning fluid.
  • cleaning devices have a cleaning head that can be moved into the interior of the hollow body to clean the interior of the hollow body in order to spray the cleaning fluid therein.
  • the cleaning device is usually attached to a line connected to an opening in the hollow body.
  • This line is, for example, a connecting piece of the hollow body or an extension on such a connecting piece.
  • the cleaning head is thus moved through this line into the interior of the hollow body and, once cleaning is complete, moved out again. In order not to have to constantly remove and install the cleaning device, it remains on this line on the hollow body.
  • the valve In order to protect the cleaning device outside the interior of the hollow body when no cleaning is taking place, the valve is provided in the line. This prevents the cleaning device from becoming contaminated, for example during a production process taking place in the hollow body, and coming into contact with the conditions prevailing therein, which could, for example, lead to a significant reduction in the service life of the cleaning device or to its failure. Contamination of the cleaning device with a product during a production process taking place in the hollow body can, for example, lead to the blockage of mechanical components of the cleaning device. In addition, the cleaning device itself would then also pose a contamination risk. Furthermore, as already mentioned, the conditions during the production process could also damage the cleaning device.
  • the hollow body is part of a roasting system, and very high temperatures prevail during production, which could damage the cleaning device, particularly sliding and sealing components. This is prevented by the valve, which separates the cleaning device and the interior of the hollow body from each other if the interior of the hollow body is not cleaned.
  • the valve is opened in order to be able to insert the cleaning head into the hollow body.
  • the problem here is that one side of the closure element facing the hollow body is in contact with the contents of the hollow body when the valve is closed and is therefore contaminated, but cannot be cleaned using the cleaning device because the closure element is not accessible to the cleaning head and the cleaning fluid sprayed by it during cleaning and therefore when the valve is open.
  • This still contaminated side of the closure element therefore represents a contamination risk for the already cleaned interior of the hollow body.
  • adhesions on this side of the closure element can severely damage the valve, for example a wiper, i.e. a sealing element in the valve, and significantly reduce its service life.
