Abstract (en)

[origin: EP0640383A1] In a process and mixer assembly, the assembly control unit is linked to inner (4) and outer (8) shafts rotating a mixer vessel (2). The inner (4) and outer (8) shafts are at an angle to each other and may be separately driven. The novelty is that the direction of rotation of the inner (4) and outer (8) shafts is periodically reversed, and that following reversal, the respective shaft is driven at a pre-determined speed of rotation; further that the speed of rotation following reversal is different from that of the previous cycle; further that the mixer assembly incorporates a control unit (16) with stored values.
