Description:
PROCESS AND SYSTEM FOR THE LINE PRODUCTION OF BAKERY FOODSTUFF

The present invention refers to a process and to a system for the line production of bakery foodstuff, particularly but not exclusively used in the production of panettone, pandoro, muffins and so on.

In the following present description reference will be made as a non-limiting example to the case of panettone .

As known, the production of a panettone provides placing a leavened dough into baking molds for the so- called final rising and the subsequent baking in the oven .

The baking molds commonly used are the so-called paper cases consisting of baking paper.

Such paper cases can have a smooth side surface or of the concertina-type.

The stacks of concertina paper cases are loaded in succession onto machines arranged to extract the single paper cases from the aforementioned stacks and to place them on a conveyor belt. Such a conveyor belt conveys the concertina paper cases in succession towards a filling station wherein a dose of dough for panettone or other bakery foodstuff is introduced into each single paper case.

After such a filling station the paper cases containing the dough are carried on a belt to a rising chamber where the final rising takes place. The paper cases coming out of the rising chamber are taken to a baking station comprising one or more ovens and, finally, to a cooling station. At the end of the cooling step the bakery foodstuff thus made is transported to a packaging station.

The production process described above suffers from some drawbacks .

A first drawback lies in the fact that the paper cases currently known are kept stacked in rows in the storehouses .

The bulk deriving from the storage of the paper cases is therefore relevant if one considers the production that is wished to be reached mainly in certain periods of the year in which panettone are highly in demand. For this reason, it is necessary to have very large storehouses .

Another drawback lies in the fact that the machine that extracts the single paper cases from the stacks must be continually loaded by an operator, since each stack can comprise no more than a few dozen of stacked paper cases in order to keep the bulk of the stack itself and, therefore, of the extracting machine, low.

This involves higher production costs since it is necessary to provide staff in charge of loading the extracting machine.

An example of a known process for producing bakery foodstuff is described in document US4114760.

The purpose of the present invention is to avoid the aforementioned drawbacks and, in particular, to devise a process and a system for the line production of bakery foodstuff that allow reducing the size of the storehouses necessary to contain the baking molds.

Another purpose of the present invention is to provide a process and a system for the line production of bakery foodstuff that allows reducing the production costs with respect to known processes and/or systems. These and other purposes according to the present invention are accomplished by making a process and a system for the line production of bakery foodstuff as outlined in the independent claims.

Further characteristics of the process and system for the line production of bakery foodstuff are the object of the dependent claims.

The characteristics and advantages of a process and a system for the line production of bakery foodstuff according to the present invention will become clearer from the following description, given as an example and not for limiting purposes, referring to the attached schematic drawings, in which:

- figure 1 is a schematic view of a system for the line production of bakery foodstuff;

- figure 2 is a schematic perspective view of a baking mold made and used in the system of figure 1; and

- figure 3 is a schematic view of a disc for making the baking mold of figure 2.

With reference to the figures, a system for the line production of bakery foodstuff is shown, wholly indicated with 10.

Such a system 10 comprises a forming machine 40 that in turn comprises a loading station adapted to be fed with at least one stack of sheets 20 of deformable material; each sheet 20 of such a stack is, in particular, shaped and arranged to be deformed so as to make a baking mold like, for example, a paper case for panettone .

The loading station is for example made through a loading plate whereonto the stacks of sheets are placed . Preferably, the sheets of deformable material are a plurality of disks 20 of paper material.

In the course of the description, for the sake of simplicity reference will be made to the disks of paper material, even though the sheets 20 can take up any shape and can consist of any deformable material.

As it can be observed in figure 3, each disk 20 comprises a central portion having a circular section 21 and a lateral portion 22 that surrounds the central portion 21. The lateral portion 22 in turn comprises a plurality of folding lines 23 arranged in a substantially radial direction so as to define a plurality of foldable wedges 24.

Preferably, a layer of a gluing promoter or primer is placed onto the lateral portion 22.

Alternatively, a hot glue layer can be placed onto each foldable wedge 24.

The forming machine 40 comprises gripping means (not illustrated) provided for picking up a sheet 20 from the at least one stack of sheets and for transferring the sheet 20 picked up to the entry of a forming station (not illustrated) arranged to deform such a sheet 20 so as to make a corresponding baking mold 30. In particular, the gripping means can comprise at least one mechanical or pneumatic arm (not illustrated) that is provided at one end with a pincer element (not illustrated) to grip the sheet 20 arranged on top of the stack.

Alternatively, the gripping means can comprise a suction element (not illustrated) capable of lifting the sheet 20 arranged on top of the stack by suction. Preferably, the forming station comprises a forming mold (not illustrated) in which the sheet of deformable material 20 received from the gripping means is deformed .

In particular, the forming mold comprises a mobile male element and a fixed female element.

Once the sheet of deformable material has been placed between the two aforementioned elements of the mold, the male element penetrates into the female element deforming the sheet 20 giving it the shape of the baking mold.

In an embodiment of the present invention the forming station also comprises means for heating the forming mold .

Such heating means preferably comprise a heater band that is positioned so as to wound the lateral surface of the forming mold and at least one thermostat for controlling the temperature of the mold provided with a temperature sensor that is positioned inside the mold. In particular, such heating means are capable of heating the forming mold at least up to the temperature triggering the gluing promoter or the temperature melting the hot glue placed on the deformable disk 20, for example 150°C.

In this way, the disk 20 is deformed by the forming mold folding around the folding lines 23 so as to take up a substantially cylindrical shape.

Further to the triggering of the gluing promoter or to the melting of the hot glue present on the single disk 20, the walls of the wedges 24 folded around the folding lines 23 glue together giving rigidity to the baking mold 30.

The production system 10 also comprises a filling station 16 arranged to place a dough into each of the baking molds 30 made and a baking station 17 arranged to perform the baking of the dough placed inside each of the baking molds in order to obtain the desired bakery foodstuff.

Once baking has been completed, the foodstuff can firstly be cooled in a cooling station 18 and then packaged for sale in a packaging station 19 in a per se known manner.

Moreover, the production system 10 can also comprise a rising station 25 arranged between the filling station 16 and the baking station 17 in which the dough placed inside the baking mold is risen for a predetermined time period that varies according to the type of dough used.

The production system 10 can advantageously comprise a conveyor belt for conveying the baking mold through the aforementioned filling 16, rising 25, baking 17, cooling 18 and packaging 19 stations.

The process for the line production of bakery foodstuff according to the present invention is as follows.

Such a production process comprises the step in which a stack of sheets 20 of deformable material is arranged in the loading station of the forming machine 40. The stack of sheets 20 is, in particular, taken from a storehouse 50.

Afterwards each sheet of the stack is transferred to the forming station of the forming machine 40 through the gripping means .

At such a forming station each sheet 20 is deformed so as to make a corresponding baking mold 30.

Once the baking mold 30 has been made, a dough is placed into it at the filling station. Such a filling step is carried out through the use of per se known dough dosers. After filling, the baking mold filled with dough is taken to the baking station where the baking of the dough is carried out in order to obtain the desired foodstuff.

Preferably, the step of making the baking mold 30 comprises the step in which each deformable sheet 20 is deformed through the forming mold.

Preferably, the step of making the baking mold 30 comprises the step in which the forming mold is heated at a temperature such as to trigger the gluing promoter or to melt the hot glue layer.

From the description that has been made, the characteristics of the process and of the system for producing bakery foodstuff object of the present invention are clear, as well as the relative advantages .

Indeed, the production process according to the present invention provides the formation of the baking mold directly in the production line. This implies that for the same amount of foodstuff you may have smaller storehouses with respect to the prior art. The bulk due to a stack of deformable sheets, indeed, is greatly less than that of a corresponding plurality of preformed baking molds.

Moreover, the stacks of deformable sheets are significantly more compact than the stacks of paper cases currently used; this allows transporting and holding an amount of sheets necessary for many hours of production close to the loading station.

Finally, it should be emphasised that the time dedicated to loading of the loading station is reduced with respect to the prior art and, therefore, the continuous presence of workers in charge of loading is no longer necessary.

For example, it is possible to load a stack of sheets sufficient for about thirty minutes of production in about fifteen seconds.

In light of the above, therefore, the costs of the foodstuff are also reduced with respect to the known ones .

It is clear, finally, that the process and the system for producing bakery foodstuff thus conceived can undergo numerous modifications and variants, all of which are covered by the invention; moreover, all of the details can be replaced by technically equivalent elements. In practice, the materials used, as well as the sizes, can be whatever according to the technical requirements .
