Abstract
A mixing device having at least one rotor supporting mixing blades that is also capable of being rotated. The device further includes an annular ring surrounding the rotor and having at least one axial opening and radial mixing openings associated with the mixing blades so as to allow the passage of the mixture therethrough. At least one particle-conveying line leads to the inside of said ring. The annular ring has a recirculation stage placed between the conveying line and the radial mixing openings and further includes at least two axially consecutive rows of radial openings.
Claims9
A mixing device comprising:
- at least one rotor supporting mixing blades and designed to cooperate with at least one motor means so as to be able to be rotated,
- an annular ring surrounding the rotor and forming the stator, said ring having at least one axial opening and radial mixing openings associated with the mixing blades for the passage of the mixture therethrough,
- at least one particle-conveying line conveying particles designed to be incorporated into said mixture and emerging inside said ring,
- wherein the annular ring has a recirculation stage positioned between the conveying line and the radial mixing openings, said recirculation stage comprising at least two axially consecutive rows of radial openings.
A method for manufacturing a preparation having at least one mixing step, the method including the following steps:
- providing a mixing assembly having a vat and at least one rotor supporting mixing blades configured to cooperate with at least one motor means,
- providing an annular ring surrounding the rotor and forming the stator, wherein the annular ring includes at least one axial opening and radial mixing openings associated with the mixing blades for the passage of the mixture therethrough,
- providing at least one particle-conveying line conveying particles configured to be incorporated into the mixture and emerging inside the ring,
- positioning a recirculation stage between the conveying line and the radial mixing openings, the recirculation stage having at least two axially consecutive rows of radial openings;
- and
- introducing particles into a mixture in the vat.
