A transport device for transporting a transportable product, especially a bulk-type product, includes an essentially cylindrical chamber containing at least one shaft which extends along the cylindrical chamber and comprises a plurality of first transport elements for transporting products in a product transport direction. The air-suspension system includes at least one compressed-air delivery device, a plurality of air-suspension bellows and valves constructed and arranged for control of the filling of one, several or all air-suspension bellows with compressed air discharged by the compressed-air delivery device. When a user interacts with the accessory device application, display changes are generated in response, in accordance with the interface definition, and are sent to a companion extension at an associated companion device. An ohmic heating element may be used to produce heat under the control of circuitry inside an electronic device and may be adjusted based on temperature sensor data.
