Kneading drum assembly for the treatment of dough comprising a) an outer drum rotatable around a kneading rotation axis with intake recesses to take in dough pieces, b) an inner drum mounted coaxially in the outer drum and rotatable relative to same, wherein c) the intake recesses configure kneading chambers, as i) the intake recesses are limited inwards by an outer shell of the inner drum and are limited outwards upon kneading by a kneading strand of a conveyor belt abutting on a circumferential section of the outer drum, d) a kneading shaft rotatable around the kneading rotation axis, which i) is drivable in a rotating manner by a first driving device and ii) is in torque proof connection with the inner drum and sets same in rotation around the kneading rotation axis, e) a second driving device for driving the outer drum in a rotating manner around the kneading rotation axis, and f) a controlling and regulating device, which coordinates at least two of the following quantities by controlling the driving devices: - a rotational speed of the inner drum, - a rotational speed of the outer drum and - an amplitude of an axial stroke of the inner drum, characterized in that the kneading drum assembly g) has a third driving device for the linear movement of the kneading shaft along the kneading rotation axis, and that h) the three driving devices (14, 15, 16) are drivable independently from one another. a) an outer drum rotatable around a kneading rotation axis with intake recesses to take in dough pieces, b) an inner drum mounted coaxially in the outer drum and rotatable relative to same, wherein c) the intake recesses configure kneading chambers, as i) the intake recesses are limited inwards by an outer shell of the inner drum and are limited outwards upon kneading by a kneading strand of a conveyor belt abutting on a circumferential section of the outer drum, i) the intake recesses are limited inwards by an outer shell of the inner drum and are limited outwards upon kneading by a kneading strand of a conveyor belt abutting on a circumferential section of the outer drum, d) a kneading shaft rotatable around the kneading rotation axis, which i) is drivable in a rotating manner by a first driving device and ii) is in torque proof connection with the inner drum and sets same in rotation around the kneading rotation axis, i) is drivable in a rotating manner by a first driving device and ii) is in torque proof connection with the inner drum and sets same in rotation around the kneading rotation axis, e) a second driving device for driving the outer drum in a rotating manner around the kneading rotation axis, and f) a controlling and regulating device, which coordinates at least two of the following quantities by controlling the driving devices: - a rotational speed of the inner drum, - a rotational speed of the outer drum and - an amplitude of an axial stroke of the inner drum, - a rotational speed of the inner drum, - a rotational speed of the outer drum and - an amplitude of an axial stroke of the inner drum, g) has a third driving device for the linear movement of the kneading shaft along the kneading rotation axis, and that h) the three driving devices (14, 15, 16) are drivable independently from one another.
