Abstract

A machine for kneading dough includes a rotating, driven tub with a flat bottom and a cylindrical tub wall and two kneading tools which engage the tub eccentrically from above and which are rotated in opposite directions, synchronously about axes that are parallel to the axis of the tub and lie in a common plane with the axis. The kneading tools consist of two hoops which have two longitudinal legs which are disposed symmetrically to their axes of rotation, in each case are connected at their ends facing the bottom of the tub by a cross leg, are fastened at their upper ends at a supporting hub and pass through cylindrical working areas which overlap one another regionally, the longitudinal legs being twisted helically relative to the direction of rotation of the hoop formed thereby. The angles of rotation of the cross legs of the hoops are mutually offset. The hoop facing the center of the tub sweeps over the axis of the tub and the working area of the hoop facing the wall of the tub is adjacent to the wall of the tub and has a direction of rotation which is opposite to the direction of rotation of the tub. The diameters of the working areas of the two kneading tools are of a diffe…
