Member for kneading dough and kneading device comprising such a member

A kneading member for a kneading device for kneading a dough, said kneading member comprising:

• a mounting roller, adapted to be rotated via a motor of the kneading device;
• a kneading tool, intended to be at least partially immersed in a mixing and kneading vessel of the kneading device and designed to mix ingredients that constitute the dough, said kneading tool comprising:
• an upper portion, extending from said mounting roller,
• a middle portion, in continuation of the upper portion, and
• a lower portion, in continuation of the middle portion, one end of which forms a lower edge of the kneading tool,
• wherein the kneading tool is formed by a circular helix blade which winding angle is not constant at least between the upper, middle and lower portions of said kneading tool, and wherein the winding angle of the lower portion of the kneading tool is smaller than that of the middle portion of the kneading tool, the winding angle of the kneading tool being defined by the angle formed by the kneading tool about an axis of rotation of the kneading member, between an upper edge at the end of the upper portion of the tool and the lower edge,
• wherein a value of the winding angle formed by the upper and middle portions of the kneading tool is comprised between about 85% and about 95% of the value of the total winding angle of the kneading tool, and wherein the value of the winding angle formed by the lower portion of the kneading tool is comprised between about 5% and about 15% of the value of the total winding angle of the kneading tool, and
• wherein the upper and middle portions of the kneading tool extend over a height comprised between about 70% and about 75% of the total height of the kneading tool, and wherein the lower portion of the kneading tool extends over a height comprised between about 25% and about 30% of the total height of the kneading tool, said total height of the kneading tool being measured between a reference plane containing an upper wall of the mounting roller and a plane parallel to said reference plane and containing the lower edge of the kneading tool.
