Abstract

The present invention relates to a device for removing fluids and/or solid substances from a mixture of particle-shaped materials with a container which forms a ring-shaped process chamber with a plurality of cells separated from each other by walls, comprising an inlet cell, intermediate cells and an outlet cell, a feeding installation for conveying the mixture to be treated into the inlet cell of the process chamber, a discharge installation for discharging the mixture treated from the outlet cell of the process chamber, a ventilation installation for feeding in a first fluidisation agent, in particular in the form of overheated vapour, from below into the process chamber through an inflow floor for generating a fluidised bed in the process chamber, a heating installation for preparing the first fluidisation agent in the flow direction before the ventilation installation, swirl impellers for conditioning the flow in the container from the process chamber to the heating installation and which in part also leads to a vapour outlet, and a dust removal installation in the flow path between the process chamber and the heating installation, wherein dust can be guided to the outlet cell via the dust removal installation, wherein in order to support a transportation of the mixture from the inlet cell to the outlet cell and/or a turbulence of the mixture in the process chamber, the inflow floor comprises first unevenness and/or at least at times a second fluidisation agent, in particular in the form of overheated vapour, can be fed at least into the inlet cell essentially parallel to the inflow floor by means of first nozzles, and/or first flow guidance members are provided above the inflow floor and/or second flow guidance members are provided below the inflow floor.
