Mixing apparatus for counterbalancing flowable masses

Apparatus for mixing flowable masses within at least one container comprising a substantially horizontal rotatable support having a substantially vertical central axis of rotation and an upper surface and a lower surface, at least one rotatable container carrier mounted on the upper surface of said rotatable support, said at least one container carrier having an axis of rotation spaced radially outwardly from and inclined inwardly towards the central axis of rotation of said rotatable support, said at least one container carrier being adapted to firmly hold said at least one container containing said flowable masses for rotation therewith, and a drive motor for rotating said rotatable support about the central axis of rotation, said drive motor being arranged coaxially with the central axis of rotation of said rotatable support below said rotatable support and adapted for separately rotating said at least one container carrier together with said at least one container containing said flowable masses about the inclined axis of rotation thereof and counter to the rotational direction of said rotatable support by means of a drive for said at least one rotatable container carrier located below the lower surface of said rotatable support, said rotatable support being rotated about twice as fast as said container carrier, said rotatable support further being provided with a means for dynamically counterbalancing centrifugal forces resulting from rotation of said at least one container carrier together with said at least one container containing said flowable masses therein, such that at all rotational speeds an equilibrium is established between the centrifugal forces acting on said at least one container carrier with said at least one container containing said flowable masses and centrifugal forces acting on said counterbalancing means.
