Device for determining the temperature of a mixture in a rotary mixer

A device (1) for determining a temperature of a mixed material (13) in a rotary mixer (2), comprising:

• a stationary housing (3);
• a mixing container (10) that can be moved on a circular path (14) into different rotational positions about a main axis of rotation (16), the mixing container (10) having
• a mixed material receptacle (9) with
• a bottom (7) and
• a side wall (8),
• wherein the mixed material receptacle (9) is in form of a solid of revolution with an axis of symmetry (11) arranged obliquely to a plane (15) of the circular path (14) and orthogonally to the bottom (7);
• and
• a non-contact measuring radiation detector (4) arranged in a stationary manner on the housing (3),
• wherein the mixing container (10) is rotatably mounted about the axis of symmetry (11),
• wherein the device (1) in an idle state (R) has no mixed material (13) and in an operating state (A) the mixing container (10) filled with mixed material (13) rotates on the circular path (14), and
• wherein radiation detector (4) is directed towards the circular path (14).
