Description

[0001] The invention relates to dough processing plants.

[0002] Devices for rounding dough, also known as belt rounders, are known from the prior art, for example from EP 0 494 600 A1. They are often used to shape loaves of bread. For this purpose, a mass of dough is placed in the device between the conveyor belts. Due to the different speeds of the conveyor belts, the dough is conveyed on the one hand and rounded on the other. Problems often arise after insertion, since the engagement between the dough and the conveyor belts required for conveying and rounding does not always occur as desired. This is particularly problematic in highly automated dough processing plants, since malfunctions can frequently occur, which on the one hand cause downtime and on the other hand require personnel intervention, which counteracts the idea of ​​automation.

[0003] The applicant's unpublished application DE 10 2021 134 478.6 describes a dough processing device that conveys a dough mass through two pairs of rollers before transferring it to a belt rounder. This allows the dough mass to be formed into a more compact shape and increases the reliability of the start-up in the subsequent belt rounder.

[0004] It is an object of the invention to provide a further improved dough processing system that enables more reliable rounding of dough masses in belt rounders. This object is achieved by a dough processing device having the features of claim 1 and by a method having the features of claim 7. Advantageous developments are specified in the dependent claims.

[0005] The dough processing system comprises a dough sheet generator configured to produce a dough sheet from an unformed quantity of dough, said dough sheet extending in the direction of a production path, and a cutting device configured to produce a dough mass by severing the dough sheet. The dough processing system further comprises a dough processing device with a winding device and a belt rounder, wherein the winding device is arranged along the production path between the cutting device and the belt rounder and is configured to wind the dough mass around an axis that is preferably oriented transversely to the production path, in particular transversely to the course of the production path through the winding device. By arranging a winding device between the cutting device and the belt rounder, dough masses of any shape can be formed into a more compact form.This can increase the reliability of the start-up in a subsequent ribbon rounder.

[0006] Axes, paths or directions oriented transversely to one another can be regarded as, for example, axes, paths or directions that enclose an angle that is, for example, greater than 0° and less than 180° and preferably 90°. A production path can be regarded as a path along which the dough or dough sheet or dough mass passes through the dough processing plant. The production path or the course of the production path can be oriented differently at different points in the dough processing plant, e.g. in different stations and / or devices of the dough processing plant. For example, the course of the path through the cutting device can be oriented transversely to the course of the production path through the winding device.

[0007] It is conceivable that the production path through the winding device is oriented transversely to the production path through the cutting device. This allows the orientation of the dough mass relative to the production path, particularly between the cutting device and the winding device, to be changed, for example, by transferring it between two conveyors whose conveying directions are oriented transversely to each other. By changing the orientation of the dough mass, the orientation of the winding axis can be influenced in such a way that the dough mass can be formed into the most compact shape possible by winding in the winding device.

[0008] The axis can, for example, be oriented transversely to a cutting direction of the cutting device. This can be particularly advantageous if the cutting device is configured to separate dough masses from the dough sheet that are shorter in the direction of the production path, particularly in the direction of the production path in the cutting device, than the dough sheet is wide. In such cases, an axis oriented transversely to the cutting direction can enable a more compactly wound dough mass.

[0009] The cutting device can be configured to separate the dough mass from the dough sheet transversely to the production path, in particular transversely to the course of the production path through the cutting device. Thus, individual dough masses can be produced with a single cut per dough mass.

[0010] The winding device can comprise, for example, a winding mat. A winding mat allows the dough mass to be wound particularly easily around an axis oriented transversely to the production path, in particular transversely to the course of the production path through the winding device. A winding mat can comprise polymer and / or metal materials.

[0011] The cutting device can comprise a cutting conveyor, and the winding device can comprise a winding conveyor. The cutting conveyor and the winding conveyor can have conveying directions oriented transversely to each other. The cutting conveyor can be configured to discharge the dough mass onto the winding conveyor. This allows the orientation of the dough mass relative to the production path to be specifically changed.

[0012] The invention also relates to a method for round-molding a dough mass. The method comprises producing a dough sheet extending in the direction of a production path from an unformed quantity of dough by a dough sheet producer, separating a dough mass from the dough sheet by a cutting device, and winding the dough mass around an axis by a winding device, wherein the axis is preferably oriented transversely to the production path, in particular transversely to the course of the production path through the winding device. The method further comprises transferring the dough mass to a belt rounder after winding by the winding device and round-molding the dough mass by the belt rounder. By winding the dough mass before transferring it to the belt rounder, dough masses of any shape can be formed into a more compact form. This can increase the reliability of start-up in a subsequent belt rounder.

[0013] The production path through the winding device can be oriented transversely to the production path through the cutting device. This allows the orientation of the dough mass relative to the production path, particularly between the cutting device and the winding device, to be changed, for example, by transferring it between two conveyors whose conveying directions are oriented transversely to each other. By changing the orientation of the dough mass, the orientation of the winding axis can be influenced in such a way that the dough mass can be formed into the most compact shape possible by winding in the winding device.

[0014] The axis can, for example, be oriented transversely to a cutting direction of the cutting device. This can be particularly advantageous if the cutting device is configured to separate dough masses from the dough sheet that are shorter in the direction of the production path, particularly in the direction of the production path in the cutting device, than the dough sheet is wide. In such cases, an axis oriented transversely to the cutting direction can enable a more compactly wound dough mass.

[0015] The method may further comprise separating the dough mass from the dough sheet by the cutting device transversely to the production path, in particular transversely to the course of the production path through the cutting device. Thus, individual dough masses can be produced with a single cut per dough mass.

[0016] It may be advantageous if the winding device comprises a winding mat. A winding mat allows the dough mass to be wound particularly easily around an axis oriented transversely to the production path, in particular transversely to the course of the production path through the winding device. A winding mat can comprise polymer and / or metal materials.

[0017] In the cutting device, the dough mass can have a greater extent transversely to the production path, in particular transversely to the course of the production path through the cutting device, than parallel to the production path, in particular parallel to the course of the production path through the cutting device. Alternatively or additionally, in the winding device, the dough mass can have a smaller extent transversely to the production path, in particular transversely to the course of the production path through the winding device, than parallel to the production path, in particular parallel to the course of the production path through the winding device. This allows the compacting effect of the winding around the axis oriented transversely to the production path to be optimized.

[0018] The method may further comprise discharging the dough mass onto a winding conveyor of the winding device by means of a cutting conveyor of the cutting device. The cutting conveyor and the winding conveyor may have conveying directions oriented transversely to each other. This allows the orientation of the dough mass relative to the production path to be specifically changed.

[0019] The invention relates to a dough processing plant and a method of the type described above. In the following, a possible embodiment is explained in more detail by way of example with reference to drawings. Fig. 1 shows a schematic perspective view of a dough processing plant. Fig. Figure 2 shows a schematic plan view from above of parts of a cutting device, a winding device and a ribbon rounder.

[0020] In Fig. 1 shows a dough processing plant 1 in a schematic, perspective view. The dough processing plant 1 can be configured, for example, for producing bread. It can comprise a plurality of components and / or devices that can be arranged one after the other along a production path P. It can comprise a dough lift 2. With the dough lift 2, delivered dough containers can be lifted in order to fill the delivered dough into the dough sheet producer 3. For this purpose, the dough sheet producer 3 can comprise a hopper 4. The dough sheet producer 3 can be configured to produce a dough sheet 5 from a still unformed dough quantity 17, which dough sheet preferably extends in the direction of the production path P.

[0021] The dough processing plant 1 can further comprise a rolling device 6. The dough sheet 5 produced by the dough sheet producer 3 can pass through the rolling device 6 after the dough sheet producer 3. The rolling device 6 can be configured to roll the dough sheet 5 to a desired thickness. The dough processing plant 1 can further comprise a cutting device 7. The cutting device 7 can be configured to separate a dough mass 8 from the dough sheet 5 by the cutting device 7, preferably transversely to the production path P, in particular transversely to the course of the production path P.

[0022] Furthermore, the dough processing plant 1 may comprise a dough processing device 9. The dough processing device 9 may comprise a winding device 10. The winding device 10 may be configured to wind the dough mass 8 around an axis 11 (see Fig. 2). The dough processing device 9 may further comprise a ribbon rounder 12. The ribbon rounder 12 may be configured to form the dough mass 8 into a round loaf. The dough or the dough ribbon 5 or the dough mass 9 may pass through the dough processing system 1 along the production path P.

[0023] In Fig. Figure 2 shows a schematic top view of parts of a cutting device 7, the winding device 10, and the ribbon rounder 12. It can now be seen that the winding device 10 can include a winding mat 13. The course of the production path P can also be seen in more detail. As in the present embodiment, the course of the production path P through the winding device 10 can be oriented transversely to the course of the production path P through the cutting device 7.

[0024] The cutting device 7 can comprise a cutting conveyor 14. The cutting conveyor 14 can be configured to convey the dough mass 8 along the production path P through the cutting device 7. The winding device 10 can comprise a winding conveyor 15. The winding conveyor 15 can be configured to convey the dough mass 8 along the production path P through the winding device 10. The cutting conveyor 14 and the winding conveyor 15 can, as shown in the exemplary embodiment, be arranged such that they have different conveying directions. This makes it possible for the course of the production path P through the winding device 10 to be oriented transversely to the course of the production path P through the cutting device 7.

[0025] In Fig.2 also shows, by way of example, a cutting direction 16 in which the dough mass 8 can be separated from the dough sheet 5. The cutting direction 16 can be oriented transversely to the production path P, in particular transversely to the course of the production path P through the cutting device 7. The axis 11 can be oriented transversely to the cutting direction 16.

[0026] An exemplary production sequence can be provided as follows. The dough lift 2 can fill the unformed dough quantity 17 into the hopper 4. The dough sheet generator 3 can form a dough sheet 5 from the unformed dough quantity 17. The dough sheet 5 can then be rolled to a desired thickness and / or width by the rolling device 6. The cutting device 7 can separate the dough mass 8 from the dough sheet 5. As shown in the exemplary embodiment, an expansion of the dough mass 8 in the cutting device 7 transversely to the production path P, in particular transversely to the course of the production path P through the cutting device 7, can be greater than parallel to the production path P, in particular parallel to the course of the production path P through the cutting device 7.

[0027] The dough mass 5 can then be transferred from the cutting device 7, in particular from the cutting conveyor 14, to the winding device 10, in particular to the winding conveyor 15. The orientation of the dough mass 8 relative to the production path P can be changed. In the winding device 10, the extension of the dough mass 8 transversely to the production path P, in particular transversely to the course of the production path P through the winding device 10, can thus be smaller than parallel to the production path P, in particular parallel to the course of the production path P through the winding device 10.

[0028] The dough mass can then be wound around the axis 11 by the winding device 10, in particular by the winding mat 13. Because, according to the present exemplary embodiment, the extension of the dough mass 8 in the winding device 10 transversely to the production path P, in particular transversely to the course of the production path P through the winding device 10, is smaller than parallel to the production path P, in particular parallel to the course of the production path P through the winding device 10, and because the axis 11 according to the exemplary embodiment is oriented transversely to the production path P, in particular transversely to the course of the production path P through the winding device 10, the dough mass 8 can be brought into a particularly compact shape.

[0029] The dough mass 8 can then be transferred to the belt rounder 12 and formed into a round loaf. QUOTES CONTAINED IN THE DESCRIPTION
