Distributor device, method of guiding materials and method of cleaning a distributor device

A distributor device for guiding materials, the device comprising:

• a process chamber (2) having at least one inlet opening (3) and having at least two outlet openings (4),
• a distributor element (5) for distributing the materials,
• wherein the distributor element (5) extends through the process chamber (2) in order to connect the inlet opening (3) to one of the outlet openings (4), wherein the distributor element (5) is arranged rotatably about an axis of rotation (6),
• a cleaning apparatus (7) which is configured to clean the process chamber (2) and the distributor element (5),
• wherein the cleaning apparatus (7) has a nozzle (70), and
• wherein the nozzle (70) is arranged on the process chamber (2) for introducing a cleaning fluid into the process chamber (2), and
• a seal (9) which is arranged at a free end of the distributor element (5),
• wherein the seal (9) is inflatable and is configured, by pressurization with compressed air via a compressed air inlet (10), to produce a material-tight seal of the distributor element (5) at the outlet opening (4), or at the outlet opening (4) and at the inlet opening (3).
