<p>The present invention relates to a kneader (10) for alimentary doughs comprising a container (20) provided with a tight lid (70) and a rotor (30) rotatably arranged in said container (20) around a vertical rotation axis (A), said kneader (10) further comprising a plurality of spraying nozzles (80) restrained to said lid (70) and arranged so as to direct their sprays towards the bottom (21) and the peripheral walls (23) of the container (20), wherein said rotor (30) comprises a flat base made up of a plurality of arms (32, 33) and a plurality of mixing paddles (34, 35) extending from said arms (32, 33) in a direction that is predominantly perpendicular thereto, and wherein the arms (32, 33) of the rotor (30) comprise chamfered surfaces (36, 37) formed along their peripheries on the sides intended to face the rotation direction (R) of the rotor (30). The mixing paddles (34, 35) comprise free ends (38, 39) that are bent towards said rotation axis (A) of the rotor (30) and inclined both with respect to the flat base of the rotor (30) and with respect to a plane (P) perpendicular thereto and passing through the rotation axis (A). Thanks to these characteristics it is possible to generate mixing movements of a swirling type on planes that are perpendicular to each other, which promote mixing between the particles of the mixtures of flours and/or meals and the ingredients injected by the nozzles and therefore the homogenization and hydration of the dough.</p> |
