DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a continuous kneading machine for doughs. More specifically, the present invention relates to a kneading apparatus which provides careful, manual-like kneading for doughs, which is especially effective for kneading wheat doughs.
SUMMARY OF THE INVENTION
In accordance with an illustrative embodiment of the present invention, a continuous kneading machine for doughs is configured with one or more pairs of identical kneading shafts, which are set within a tub-shaped container partially filled with dough, which has an open top. The kneading shafts are located below the surface level of the dough, and are synchronously counterrotated in pairs by an external drive mechanism. A series of longitudinally adjacent U-shaped bracket components are attached to each kneading shaft, with each bracket component being angularly offset relative to each other around the circumference of the kneading shaft. The U-shaped bracket components are each inclined in the direction of motion, such that they form a helical profile along the kneading shaft.
The angle of offset in the longitudinal direction between corresponding legs of adjacent bracket components around the circumference of the kneading shaft is, advantageously, 22.5.degree.. Moreover, the opposing pairs of bracket components located at corresponding longitudinal positions on their respective kneading shafts are rotationally offset towards one another, advantageously, by 45.degree.. As a result, a "manual" kneading simulation is achieved, which is especially effective for wheat doughs.
An illustrative embodiment of the present invention is more fully described below in conjunction with the following drawings:

DETAILED DESCRIPTION OF THE INVENTION
According to one embodiment, the present invention is a kneading machine, as depicted in FIG. 1. The machine is composed of a longitudinal container 1 which has the shape of a tub and is open at the top and of two synchronously driven kneading shafts 2a, 2b which counter-rotate. Within the trough 1 there is disposed premixed dough material which is filled up to the level of indicator line 3.
As is shown in FIGS. 2 and 3, each of the synchronous shafts 2a, 2b is provided with kneading elements, of which each individual one has the shape of a U-shaped bracket, both of whose legs are attached to the shaft, with the base side of the U-shaped kneading element facing outwardly.
There are provided a plurality of two mutually diametrically opposite kneading elements for each shaft. In the longitudinal direction of the shafts 2a, 2b the individual kneading elements are adjacent nearly without any gap in between and form a helical profile as is outlined in FIGS. 2 and 3.
This occurs in such a way that in the longitudinal direction the respective following kneading element is arranged offset towards the previous element by a specific angle around the shaft circumference, e.g. 22.5.degree.. Moreover, as is shown in FIG. 1 especially, each kneading element is slightly inclined in the direction of motion.
The kneading elements of the one kneading shaft 2a are offset by 45.degree. towards the second kneading shaft 2b (FIG. 1).
The spatial arrangement of the kneading elements can be seen in the top view according to FIG. 2.
FIG. 4 shows a representati
