A kneading machine comprises a substantially cylindrical tank (40), and at least one kneading implement (26), which can turn within the tank (40), about an axis substantially parallel to the axis of the tank so as to define a theoretical cylinder. The kneading implement comprises at least two or more arms all extending substantially on the periphery of the respective theoretical cylinder so that said arms perform an orbital movement about the axis of rotation of the implement. Each arm, at least for a part of its length, is substantially rectilinear and set in a direction substantially parallel or slightly inclined with respect to a generatrix of the respective theoretical cylinder. The arms of the kneading implement are set at unequal angular distances apart about the axis of rotation of the implement in such a way as to be relatively grouped together in one or more angular ranges of the surface of said theoretical cylinder. The implement preferably co-operates with a similar implement or with a fixed contrast member.
