Description

[0001] Textile baking mat for supporting baked goods during a baking process and support assembly for baked goods in an oven with such a textile baking mat

[0002] The content of the German patent application DE 10 2024 203 460.6 is incorporated herein by reference.

[0003] The invention relates to a textile baking mat for supporting baked goods during a baking process. Furthermore, the invention relates to a support assembly for baked goods in an oven with such a textile baking mat.

[0004] Baking trays or metal racks are known for supporting baked goods during a baking process. EP 3 926 241 A1 discloses a tray for baked goods. WO 2006 / 073 566 A2 discloses a baking tray. EP 2 002 723 B1 discloses a fermentation tray with an insert and a method for loading a fermentation tray with an insert.

[0005] It is an object of the present invention to improve a baking base for supporting baked goods, in particular with regard to baking energy efficiency.

[0006] This object is achieved according to the invention by a textile baking mat having the features specified in claim 1.

[0007] The invention recognizes that the advantages of textile materials, particularly their lower heat capacity, are particularly advantageous when used for a supporting baking mat. Aramid fibers have proven particularly advantageous for the base material because they are food-safe, heat-resistant, and dimensionally stable. The non-stick coating ensures that baked goods can be easily removed from the textile baking mat after baking. The surface weight ensures sufficient stability of the baking mat. The textile baking mat can be designed to be particularly permeable to air.

[0008] The basis weight of the textile base material can be in the range between 50 g / m 2 and 250 g / m 2 and especially in the range between 50 g / m 2 and 200 g / m 2 , for example in the range between 100 g / m 2 and 125 g / m 2 lay.

[0009] The non-stick coating can be applied as a doctor blade coating or as a calender coating.

[0010] A non-stick coating layer according to claim 2 has proven particularly advantageous with regard to the combination of the properties "non-stick effect," "dimensional stability," and "influence on air permeability." The non-stick coating layer refers to the basis weight of the non-stick coating material on the textile base body. The total basis weight of the coated textile base body therefore includes both the basis weight of the base material and the basis weight of the non-stick coating.

[0011] The non-stick coating can be in the range between 50 g / m 2 and 200 g / m 2 , especially in the range between 50 g / m 2 and 150 g / m 2, lie. Silicone as a non-stick material according to claim 3 is a substantially inert material, particularly food-safe, when used for the textile baking mat. The silicone coating can be grease-resistant. The silicone coating can be implemented as an LSR or HTV coating. Alternatively, the non-stick coating can be PTFE-based.

[0012] Air permeability according to claim 4 leads to particularly good baking results. By specifying a target air permeability, a good combination of baking effect from the hot air flowing around the baked goods and minimal drying of the baked goods due to the hot air flowing around them can be achieved, particularly tailored to the baked goods. In extreme cases, the textile baking mat can also be air-impermeable (air permeability 0 l / m 2 / s). The air permeability of the textile baking mat can be in the range between 0.1 l / m 2 / s and 500 l / m 2 / s, in the range between 1 l / m 2 / s and 500 l / m 2 / s, in the range between 10 l / m 2 / s and 500 l / m 2 / s, in the range between 50 l / m 2 / s and 500 l / m 2 / s, in the range between 100 l / m 2 / s and 400 l / m 2 / s or in the range of 250 l / m 2 / s and 350 l / m 2 / s lie.

[0013] Staple lengths according to claim 5 have proven particularly suitable for ensuring dimensional stability and sufficient load-bearing capacity. Alternatively, long-staple yarn, medium-staple yarn, short-staple yarn, and endless yarn are possible. The staple length can be between 40 mm and 100 mm, in particular between 50 mm and 90 mm.

[0014] A fabric according to claim 6 results in a textile baking mat with a particularly good combination of the aforementioned properties. The fabric can be in the form of a 3D fabric. As an alternative to a fabric, the textile base material can also be in the form of a scrim, a braid, a machine-woven fabric, or even a nonwoven.

[0015] An identification marker according to claim 7 makes it possible, in particular, to distinguish an individual textile baking mat from another textile baking mat of a used plurality of corresponding baking mats. This can be used, in particular, to document the number of baking and / or washing cycles performed with the textile baking mat. Multiple identification markers can also be used. The identification marker can be in the form of an RFID chip. Alternatively or in addition to an RFID chip, a barcode or a QR code can also be used as an identification marker. It can also be used to control an oven, provided details of the baking program are stored in the identification marker.

[0016] The advantages of a support assembly according to claim 8 correspond to those already explained above with reference to the textile base. The support frame gives the support assembly additional load-bearing and dimensional stability. The dimensions of the support frame can correspond to those of standard baking trays, so that the support assembly can easily be used as an alternative to a conventional baking tray. The support frame serves to hold and, if necessary, tension the textile baking base. With regard to the baked goods themselves, the support frame has no supporting function. The baked goods are therefore carried exclusively by the textile baking base without being supported by the support frame. Designs of the support frame according to claims 9 and 10 have proven to be particularly suitable. In particular, this results in a comparatively simple separation of the textile baking base from the support frame, which can be used to prepare for a washing process.If the support frame includes tubular sections, these can be designed to completely surround the textile base or in sections. The dimensions of the support frame can be adapted to standard baking tray dimensions.

[0017] Screws and / or snap fasteners or other locking elements can be used as fastening elements.

[0018] Embodiments of the invention are explained in more detail below with reference to the drawings, in which:

[0019] Fig. 1 shows a support assembly for baked goods in an oven, comprising a textile baking base and a support frame for the same;

[0020] Fig. 2 is a plan view of a section of the textile baking mat;

[0021] Fig. 3 in comparison to Fig. 2 shows an enlarged detail of the textile baking mat to illustrate a weave of the fiber base material;

[0022] Fig. 4 shows a section along line IV-IV in Fig. 3; and Figs. 5 to 7, each in a representation similar to Fig. 3, show further variants of weaves for the fiber base material of the textile baking mat.

[0023] Fig. 1 shows a perspective view of a support assembly 1 for baked goods in an oven. The support assembly 1 can be used as an alternative to a conventional baking tray, for example, in a rack oven, but also in a household oven.

[0024] The support assembly 1 has a textile baking base 2. The textile baking base 2 is used to support baked goods, for example rolls or bread, during a baking process. Fiber or filament material, in particular in the form of aramid fibers 4, serves as the base material for a textile base body 3 (see Fig. 4) of the baking base 2. The aramid fibers or filaments 4 are made of para-aramid. The aramid fibers 4 are designed as yarns with a staple length between 30 mm and 120 mm or as continuous filaments. The yarn is in particular a long-staple yarn. A medium-staple yarn, a short-staple yarn, or even a continuous yarn is also possible.

[0025] The textile base body 3 is in the form of a woven fabric with warp and weft threads. Figures 2, 3, and 5 to 7 provide examples of possible weaves. The weave can be a plain weave, a leno weave or a waffle weave (see Figure 5), a broken twill weave (see Figure 6), a flat twill weave (see Figure 7), a rib weave, or a panama weave.

[0026] The fabric can be designed as a 3D fabric. Alternatively, the textile base body 3 can be in the form of a scrim, a braid, a knit, or even a nonwoven.

[0027] The uncoated textile base body 3 has a basis weight in the range between 50 g / m 2 and 250 g / m 2 .

[0028] The textile base body 3 of the baking mat 2 has a non-stick coating 5. A coating, i.e. a surface weight, of the non-stick coating 5 on the textile base body 3 is in the range between 50 g / m 2 and 300 g / m 2 . The coating can be applied to one or both sides of the textile base body 3.

[0029] The non-stick coating 5 is applied over the entire surface of the textile base body 3.

[0030] The non-stick coating 5 can be implemented as a silicone coating. Liquid silicone rubber (LSR) or HTV silicone is used as a doctor blade or calender coating. Alternatively, the non-stick coating 5 can be implemented using PTFE.

[0031] A Shore A hardness of the non-stick coating 5 is in the range between 8 and 50, measured according to DIN ISO 7619-1.

[0032] The silicone material of the non-stick coating 5 is a grease-resistant silicone material. The air permeability of the textile baking mat 2, i.e., the textile base body 3 coated with the non-stick coating 5, is in the range of 0 l / m 2 / s and 500 l / m 2 / s. The air permeability of the textile baking mat 2 can be in the range between 0.1 l / m 2 / s and 500 l / m 2 / s, in the range between 1 l / m 2 / s and 500 l / m 2 / s, in the range between 10 l / m 2 / s and 500 l / m 2 / s, in the range between 50 l / m 2 / s and 500 l / m 2 / s, in the range between 100 l / m 2 / s and 400 l / m 2 / s or in the range of 250 l / m 2 / s and 350 l / m 2 / s lie.

[0033] The air permeability of the textile baking mat 2 was tested on a TEXTEST FX 3300 Lab Air IV device with a test area of ​​20 cm 2and a test pressure of 200 Pa.

[0034] The air permeability of the textile baking base 2 ensures good air circulation, especially of hot air during baking around the baked goods supported by the textile baking base 2.

[0035] In an alternative embodiment, the textile base body 3 can be coated with the non-stick coating 5 over its entire surface and in an airtight manner in the initial step, followed by perforation of the thus coated textile base body 3.

[0036] The surface weight of the textile baking mat 2 including the non-stick coating 5 is in the range between 150 g / m 2 and 550 g / m 2 , especially in the range between 150 g / m 2 and 250 g / m 2 .

[0037] The textile baking mat 2 has an identification marker 6 (see Fig. 1) supported by the textile base body 3. The identification marker 6 is an RFID chip. The RFID chip can be a thin film chip. Alternatively or additionally, a barcode or QR code can also be used as the identification marker 6.

[0038] The textile baking mat 2 is washable. Even after washing, the textile baking mat 2 retains its shape.

[0039] The textile baking mat 2 is food safe.

[0040] The textile baking mat 2, tested for crease recovery according to ISO 9867, has only a slight to negligible tendency to crease.

[0041] The support assembly 1 further comprises a support frame 7 which runs around the textile baking base 2 and in particular around the textile base body 3, at least in sections.

[0042] In the embodiment shown in Fig. 1, the support frame 7 is designed as a support frame that completely surrounds the textile base body 3. The textile baking mat 2 and in particular the textile base body 3 are fixed to the support frame 7 via fastening means 8, which can be screws. Snap fasteners can also be used as fastening means.

[0043] In an alternative, not-shown embodiment of the support frame 7, it comprises several tube sections. These frame tube sections can be connected to each other by plug-in connections or screw connections. In this case, the textile baking mat 2 is held to the tube sections, for example, by loops that are attached to the textile base body 3 or molded onto it.

[0044] The support assembly 1 is used for baking in a similar way to a conventional baking tray. The baked goods are supported by the textile baking base 2, thus, they are not supported by any other component. The textile baking base 2 has a low heat capacity compared to a baking tray, which leads to significant energy savings during the baking process, which can be in the range of 10%. The non-stick coating 5 ensures that the baked goods can be easily removed from the textile baking base 2 after baking.

[0045] The textile baking mat 2 retains its shape even after multiple or numerous baking processes and is heat-resistant up to a temperature of at least 250°C and, regularly, up to a temperature of at least 300°C. During the baking process, no significant outgassing of substances that are hazardous to health occurs.

[0046] User information about the individual textile baking mat 2 can be stored on the RFID chip 6, for example, the number of baking cycles and / or the number of wash cycles and / or information about the baking program being performed. It is then possible, for example, to control a suitably equipped oven via the RFID chip using the respective support assembly 1.
