A kneading member for a kneading device of 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 a dough, said kneading tool comprising: • an upper portion, extending from said mounting roller, • a middle portion, in the continuation of said upper portion, and • a lower portion, in the continuation of said middle portion, one end of which consists of a lower edge of the kneading tool, the kneading tool consists of a circular helix blade which winding angle is not constant at least between said upper, middle and lower portions of said kneading tool, the winding angle of the lower portion of said kneading tool is smaller than that of the middle portion of said kneading tool, the winding angle 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 kneading tool and the lower edge the kneading member being characterized in that: - the value of the winding angle formed by the upper and middle portions of the kneading tool is comprised between 85% and 95% of the value of the total winding angle of the kneading tool, and in that the value of the winding angle formed by the lower portion of the kneading tool is comprised between 5% and 15% of the value of the total winding angle of the kneading tool and in that, - the upper and middle portions of the kneading tool extend over a height comprised between 70% and 75% of the total height of the kneading tool, and in that the lower portion of the kneading tool extends over a height comprised between 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 (P') parallel to said reference plane and passing through the lower edge of the kneading tool. - a mounting roller, adapted to be rotated via a motor of the kneading device;
