  • the exit opening 97 bounded inwardly a central, pyramid-shaped counter-cone 98, which is in the opposite direction to the conveying direction 5 to the center tapered towards whose guide walls 99 so also fall to the exit opening 97 out.
  • the configuration of the cone section 95 according to FIG. 6 favors a well-distributed transfer of the bulk material from the cone section 95 in the downstream buffer section 21 and thus leads to a good drying performance by the in the opposite direction to the conveying direction 5 through the outlet opening 97 flowing drying gas.
  • a circular exit opening may also be present.
  • the cone ring 96 and the counter cone 98 can also be designed as rotationally symmetrical cones.
  • the amounts of gas in the various supply lines can also be specified by means of a control circuit, not shown, depending on the drying capacity to be achieved. This can be done, for example, depending on the degree of moisture of the supplied bulk material and / or depending on the supplied bulk flow, the bulk material temperature, the type of bulk material or other parameters.
  • FIG. 3 can be a view of the bulk material during drying accomplish.
  • FIG. 3 are separated from the other bulk material 49 to be separated during the viewing dust particles with 100. These dust particles are removed via the suction line 90 and can later be separated from the drying gas via a separator cyclone and / or a filter.
  • an absorption dryer For drying the drying gas prior to its introduction into the entry module and / or the heat exchanger module, an absorption dryer can be used.
