Definitions

  • the invention relates to a mixer dryer according to the preamble of patent claim 1.
  • Such a dryer is usually heated via the housing and the mixing screw.
  • the heat required to dry the product is brought into the product by contact with the heating surfaces of the housing and the mixing screw.
  • the mixer dryer has the option of introducing energy into the product via microwaves, in which it is converted into heat.
  • European patent application 0 306 563 a cone mixer dryer is known in which the mixer screw is driven from above by means of a drive arranged centrally in the cover via an angle lever. Between the drive and further built-in components arranged in the cover, a microwave generator, known as a magnetron, is provided, through which microwaves are applied to the material to be dried in the mixer dryer.
  • the material to be dried is partially covered by the rotating angle lever so that it is not constantly and evenly reached by the microwaves emitted by the magnetron.
  • the space available for the magnetron is very restricted by the drive unit.
  • the invention is therefore based on the object of impinging a mixer dryer as freely and as uniformly as possible with microwaves in order to achieve a shorter drying time and a more gentle drying.
  • the invention thus enables a particularly effective drying of the product in that, in addition to heating the container and the mixing screw, energy can be introduced into the product without hindrance via microwaves.
  • a cylindrical intermediate ring is provided between the mixing container and the lid, on which one or more magnetrons are arranged.
  • the intermediate ring enables the attachment of any number of magnetrons distributed over the circumference of the container without obstruction or constriction of the parts arranged on the lid, such as inlet connectors, vapor filters and sight glasses.
  • the microwave exposure can advantageously take place via one or more magnetrons and coaxial lines, as a result of which the number of magnetrons can be reduced.
  • coaxial lines can also start from one magnetron.
  • the combined contact and microwave drying can greatly shorten the drying time compared to normal vacuum drying and the product can be dried more gently when the internal moisture evaporates.
  • a vapor filter 3 and a product inlet nozzle 4 are arranged on the cover 2.
  • a product discharge nozzle 5 and a drive 6 are provided which drive an overhung mixing screw 7.
  • a magnetron 8 is additionally arranged on the cover 2.
  • an intermediate ring 9 is inserted between the mixing container 1 and the lid 2, on which two magnetrons 10 and 11 and associated coaxial lines 12 and 13 are provided.
