<p>The apparatus comprises a frame carrying a motor (2), a vertically disposed shaft (6) driven in rotation by the motor, a cone-shaped surface centrifugal aerator (4) driven in rotation by the motor in a first direction of rotation, a mixer (8) driven in rotation by the shaft, a control unit to drive the shaft in a second direction of rotation, a device for activating or deactivating the aerator, an unidirectional rotation transmission device (14), and a guide conduit positioned between the mixer and the aerator. The shaft is immersed in the liquid composition. The apparatus comprises a frame carrying a motor (2), a vertically disposed shaft (6) driven in rotation by the motor, a cone-shaped surface centrifugal aerator (4) driven in rotation by the motor in a first direction of rotation, a mixer (8) driven in rotation by the shaft, a control unit to drive the shaft in a second direction of rotation, a device for activating or deactivating the aerator, an unidirectional rotation transmission device (14), and a guide conduit positioned between the mixer and the aerator. The shaft is immersed in the liquid composition. A centrifugal blade is fixed on the aerator. A position of aerator is identical in the first and second direction of rotation. The mixer is formed with an axial impeller. An axis of shaft coincides with an axis of revolution of a cylindrical section of the conduit. An axis of rotation of the aerator and an axis of rotation of mixer are parallel to the shaft. The frame comprises a pillar laying at a bottom of the tank. An independent claim is included for a process for mechanical treatment of liquid composition in a tank.</p> |
