Heating and cooling mixers

Dl «- invention relates to a heating and cooling mixer for processing of plastics, consisting of a double-walled standing container with a lid that can be closed with an ir * container interior arranged double-walled internals for heating or Coolant flow and rotating at the bottom Tool,

Such double-walled internals with heating or coolant flow are required to allow the heated material to be mixed quickly with larger contact surfaces; cool down and thus the throughput of the To be able to increase the mixing plant.

It is known to work in parallel in double-walled heatable mixers one or two concentric double-walled xge to the container shell to arrange flat rings through which heating or coolant flows, between which the mix is moved.

The disadvantage of this procedure is that the mix is in accumulates in the gap between the rings and depending on the property of the material also clumped together in kiumpen. A steady circulation and represents a uniform scorching of the mixed material is therefore 'it> place.

Ir invent * 'g the give up is based on the shape and the attachment of additional double rain ιβ, τκ ^3' gen installations with heating '' or KUhlmittei.ai to make 3Chluß so that the mix without Stauersc.ieinungen circulate irr mixing vessel - »Nd can be cooled evenly.
