Method for operating a cellular wheel sluice and cellular wheel sluice for carrying out the method

A cellular wheel sluice for carrying out the method for operating a cellular wheel sluice (1;

• 22), wherein the cellular wheel sluice (1;
• 22) has:
• a housing (2)
• with a feed shaft (3) opening from above into the housing (2),
• with an outlet shaft (5) opening downwardly out of the housing (2),
• a cellular wheel (10), which is arranged between the feed shaft (3) and the outlet shaft (5) and is arranged to be rotationally drivable about a horizontal rotational axis (9a) in a cylindrical cellular wheel housing portion (4) of the housing (2),
• a cellular wheel drive shaft (12), which is non-rotatably connected to the cellular wheel (10) and is rotatably mounted in the housing (2),
• comprising the following steps:
• applying a pressure drop, a higher pressure being present in the feed shaft (3) than in the outlet shaft (5),
• operating the cellular wheel (10) during the product conveyance between the feed shaft (3) and the outlet shaft (5) at a rotational speed such that an outer periphery of the cellular wheel (10) reaches a speed, which is greater than 0.6 m/s
• wherein when applying the pressure drop in the feed shaft, a pressure is applied, which is higher than normal pressure.
