Abstract
A kneading machine for flour-based mixes, particularly for bakery products, comprises two kneading implements turning within a rotating tank having a cylindrical shape, with concordant directions of rotation, about two axes, which are parallel to the axis of the tank and are set at a distance from the axis of the tank so as to describe two theoretical cylinders that are substantially tangential both with respect to one another and with respect to the circumferential wall of the tank. Each arm describes an orbital movement about the respective axis of rotation and is set inclined with respect to a straight line generatrix of its theoretical cylinder.

A kneading machine comprising:
- a rotating tank that is substantially cylindrical;
- and
- a pair of kneading implements turning within the tank, with concordant directions of rotation, about two axes parallel to the axis of the tank, which are substantially tangential both to one another and to the circumferential wall of the tank,
- wherein:
- each implement comprises at least one arm;
- each arm extends on the periphery and from one end to the other of the theoretical cylinder that has an axis that is coincident with the respective axis of rotation of said arm, in such a way that said arm describes an orbital movement about the respective axis of rotation;
- each arm, at least for a part of its length, is inclined with respect to a straight line generatrix of said theoretical cylinder parallel to said axis of rotation of the arm;
- the opposite ends of the two arms are staggered with respect to one another, viewed in the direction of the axis of rotation, by an angle smaller than 180° about said axis of rotation;
- means are provided for causing said arms to have orbital movements about the respective axes of rotation that are synchronized with respect to one another, in such a way that the arms pass simultaneously in the area of tangency of the respective theoretical cylinders, intersecting one another with opposite directions of movement on account of the concordant rotation of the two implements,
- wherein the aforesaid angle of staggering of the two opposite ends of each arm is between 20° and 100°, and is preferably between 20° and 45°.
