DESCRIPTION:

BRIEF SUMMARY
FIELD OF THE INVENTION

The invention relates to the production of endless strips of dough, consisting particularly of flour and water, which on heated, mobile and endless baking surfaces are transformed into endless dried strips through a drying or baking process. This strips are rolled up and temporarily stored as endless strips for further processing, or subdivided into separate layers and temporarily stored as layers for further processing, or separated into separate layers immediately after production, the separate layers being formed into three-dimensional objects, or are formed into three-dimensional objects immediately after production and subsequently separated into individual objects.


BACKGROUND OF THE INVENTION

Baking devices are known for preparing or producing endless strips of a food product, whereby a fluid or pasty dough consisting mainly of flour and water is continuously applied onto a continuously revolving baking surface and there transformed into an endless dried strip through a drying or baking process, this strip being continuously removed from the revolving baking surface.
Such baking devices are equipped with a continuously revolving baking surface carrier heated on its internal and external sides, which carries the revolving baking surface on its external side and transports the same through an external stationary baking zone, at whose beginning a dough application device and at whose end a strip removal device are provided. The dough application device forms an uninterrupted dough strip on the revolving baking surface, which is at least partially baked in the baking zone and at the end of the baking zone is continuously removed from the baking zone by the strip removal device.
In most cases a rotating baking drum is used as the revolving baking surface carrier. The hub of the baking drum is rotatably supported on a horizontally arranged rotation axle. The cylindrical shell of the baking drum is connected with the hub by a support structure and carries the baking surface on its outside. The baking drum surrounds a space containing the support structure and the hub of the baking drum, which also contains the heating device for the heating of the inner drum shell. The baking drum is surrounded by an outer space which contains the dough application device and the strip removal device of the outer stationary baking zone arranged successively in the rotation direction of the baking drum, as well as a heating device for heating the outer surface of the drum shell.
Such baking devices are used for producing baked goods, and for the production of endless wafer strips, which when still warm from baking can be plastically shaped and are further processed in continuously operating production lines to separate objects which in the cooled state are crisp and solid. The endless wafer strips which can be plastically shaped are produced from wafer dough with a high sugar content, which contain 25 to 100% by weight sugar in relation to the flour content of the wafer dough. The objects consisting of sugar-containing wafer dough can represent a final wafer product or an intermediate product in the production of other sweets, e.g. cream-filled wafers or chocolate-coated wafers, candy with fillings, etc. The objects made of plastically shaped sugar-containing endless wafer strips are for instance whole hollow bodies, such as deep cups, wafer rolls, hollow shells, wafer cones, ice cream cones, or also parts of hollow bodies interconnected by layer strips and which together with the layer strips form separate rectangular wafer layers provided with depressions formed by the hollow bodies, or also flat bowls, plates, flat slices, etc.
In the cylindrical baking drums of the known baking devices heat losses result due to the heating of the drum hub and of the support structure form-fittingly connecting the hub with the drum shell. Depending on the construction of the baking drum, the support structure can comprise two radial support plates arranged on the lateral margins of the drum shell, or a single su
