Model for shaping and cutting out milled dough

The invention relates to a model for shaping and cutting out Milled dough, especially for biscuits and the like.

According to the procedures currently used to remove from fulled To obtain dough cut pieces that correspond to the desired biscuits, so-called swinging or pendulum cutting machines or pressing used. Such cutting machines, which are mounted above a conveyor belt that transports the rolled out dough are provided with a number of models made of a metal, in particular of bronze.

These molds or models have a part which is stationary with respect to the vibrating cutter in which the biscuit is placed being molded and moving parts that are actually pullers for the homogeneous separation of the dough from the cookie cutter or model.

Because the embossing and cutting of the milled dough at the same time be carried out, this must be taken into account when lifting the cookie cutter.

Formed biscuit to be separated from the mold and attached to the canvas conveyor belt stick, which it then transports to the baking station. This type of model has several disadvantages.

Since it consists of a metallic material, in particular bronze, it has considerable weight, and the cutting machine, which simultaneously supports a large number of models, has considerable weight large moving masses, and therefore requires a large amount of power.

In addition, the presence of pull-out devices requires that Control devices are provided, which act on the movement of the extractor at the right time so that the Loosen the dough sticking to the cookie cutter.

In practice, such pullers typically include a number of cylindrical elements passing through the body or the housing of the cutter itself are guided and made this push out at the moment in which the dough is to be thrown off.

These movements made with one of the pendulum motion of the swaying Stamping machine take place at the same frequency, cause a continuous creep of the metal surface of the bearing of the extractor and the extractors themselves.

Taking into account that the material in this case is an edible one If the dough is dough, then it is completely impossible to lubricate these areas and surfaces, as the lubricant enters the edible dough.

909817/0874

seep and have an unpleasant effect on the end product.

That is, the extractors must operate dry, i.e. that on the one hand they have to work slower in order not to generate excessively high frictional forces and on the other hand that an unavoidable one premature wear of the model parts is the result.

All of this results in a fairly high operating cost for biscuit making according to the construction described above.

The object of the invention is thus to create a model that does not have any movable pull-out devices. According to the invention a model is provided in which the separation of the cut and shaped dough is automatically simple occurs that the cookie cutter is lifted from the dough that has been rolled out. In a further embodiment of the invention, a model be created in lightweight construction so that the swinging or pendular part of the cutter does not go back and forth excessively is exposed to ongoing loads, whereby their power requirements can be kept low.

The object of the invention is achieved by a model for shaping and cutting out fulled dough, in particular for punched biscuits and the like., characterized in that the model comprises a cutter or press, which the negative shape of the has biscuits to be produced, further in that it consists of a plastic from the group of polyamides, further in that that the cookie cutter or press is processed so that

909817/0874

their surfaces are extremely smooth and uniform, and that the Plastic has dough-repellent properties and prevents the dough from sticking to the cookie cutter and ultimately, that the model is provided with a sharp edge in order to simultaneously make a cut with the cutout.

The invention is explained in more detail below. All in the description Features and measures contained therein can be essential to the invention. The drawings show: Fig. 1 is a plan view of the cutter according to the invention.

FIG. 2 shows a section along the line II-II in FIG. 1

of the model according to the invention. Fig. 3 shows the particular shape of the cutting edge for the

Dough.

The model according to the invention essentially comprises a parallelepiped block 1 with two lateral lugs 2 and 3, in which four holes 4 are formed, around the block on the swinging or pendulum part to attach a cutting or pressing machine.

The surface 5 of the parallelepiped, that of the pendulum part of the cutter Adhesive surface 6 is opposite, is processed so that it forms a negative impression of the biscuit to be produced.

In this case, a number of small pins 7 from small round head cylinders are provided, which are let into the model housing and serve to replicate the traditional fine pin pattern in the To produce biscuits.

909817/0874

The rounded edge 8 at the corners fulfills the double task, the Shape the biscuit and cut it out of the dough mass.

For this reason, according to FIG. 3, it has the cross-section of an equilateral triangle with a chamfered apex Angle of inclination Ck be approx. 20.

The material used for the model is from the group of polyamides is selected and the cookie cutter must be machined with great precision to achieve very smooth surfaces.

The material processed in this way is very low Adhesion coefficients for materials such as edible dough, and the angles of inclination of the edge that performs the cutting process, are chosen so that the material cannot adhere after the cutting process is finished.

In practice, the shaped biscuit that does not come loose on the model can adhere by itself during the stroke cycle of the model or it separates automatically due to its own weight, whereby the There is no need for extractors.

The advantages offered are essential to the invention: The swinging one Part of the cookie cutter now carries very light cookie cutters, there are no moving devices or devices subject to friction also no clock controls to trigger the pull-out process.

This leads to reduced power consumption by the machine, to a longer service life of the model and the other

909817 / 087A

components of the machine.

Another advantage is an improved environmental friendliness as a result of a practical reduction in the noise level due to the elimination of all moving parts.

Of course, the invention can also be applied to the construction of models of other shapes, in particular the polyamide can also be used for the biscuit mold by providing them with a support of a baking device made of a different material will.

One of the preferred plastics used in accordance with the invention is PTEF, known under the brand name "Teflon".
