1. A fluidized bed reactor apparatus, comprising:
a cylindrical reactor chamber having a rotating shaft equipped with radially extending fluidization blades disposed in the reactor chamber, said rotating shaft is connected to a drive unit, one or more inlets for feeding fluidizing bed material into the reactor chamber, creating a fluidized bed in the reactor chamber, and for feeding organic material that shall be processed into the fluidized bed in the reactor chamber, and
one or more outlets for discharge of material, gases and/or vapors from the reactor chamber, wherein the apparatus further comprises
a mechanical separator chamber connected to the rotating shaft of the reactor chamber, said separator chamber being an apparatus for mechanical separation of dust particles in the gas and/or vapor stream received from the reactor chamber, and which comprises separation blades rotating around an axis of said rotating shaft, mechanically separating dust particles from the gas and/or vapor stream,
a control system connected to the drive unit driving the rotating shaft, said control system being connected to sensors in the reactor chamber and in the mechanical separator chamber, and
wherein said apparatus comprises sealing and support bearings at each end of the reactor chamber, said sealing and support bearings having inert gas flushing,
wherein said apparatus comprises a polishing chamber connected to the mechanical separator chamber, said polishing chamber being an apparatus for removing particles in the gas and/or vapor stream received from the mechanical separator chamber, and
said polishing chamber comprises a housing with an internal screw, forcing the gas and/or the vapor to follow the screw trajectory, and circulation means for circulating a cleansing fluid over surfaces in the polishing chamber.
