Description

[0001] 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 comprising such a textile baking mat.

[0002] Baking trays or metal racks are known for supporting baked goods during baking. EP 3 926 241 A1 discloses a tray for baking goods. WO 2006 / 073 566 A2 discloses a baking tray.

[0003] 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.

[0004] This object is achieved according to the invention by a textile baking mat having the features specified in claim 1.

[0005] The invention recognizes that the advantages of textile materials, particularly their lower heat capacity, are particularly well-suited for use as 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 breathable.

[0006] 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.

[0007] The non-stick coating can be applied as a doctor blade coating or as a calender coating.

[0008] 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.

[0009] 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 , lay.

[0010] 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.

[0011] 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 / m2 / 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.

[0012] 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 continuous yarn are possible. The staple length can be between 40 mm and 100 mm, in particular between 50 mm and 90 mm.

[0013] 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.

[0014] 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.

[0015] The advantages of a support assembly according to claim 8 correspond to those already explained above with reference to the textile baking base. The support frame provides the support assembly with 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.

[0016] Designs of the support frame according to claims 9 and 10 have proven to be highly suitable. In particular, this allows for a comparatively simple separation of the textile baking mat from the support frame, which can be used for preparing a washing process. If the support frame has tubular sections, these can be designed to surround the textile base completely 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: Fig. 1 a support assembly for baked goods in an oven, comprising a textile baking base and a support frame for the same; Fig. 2 a top view of a section of the textile baking mat; Fig. 3 compared to Fig. 2 shows an enlarged detail of the textile baking mat to illustrate the weave of the fibre base material; Fig. 4 a section along line IV-IV in Fig. 3; and Fig. 5 to 7 in each one to Fig. 3 similar illustration further variants of fabric weaves for the fiber base material of the textile baking mat.

[0020] The support assembly 1 has a textile baking base 2. The textile baking base 2 serves to support baked goods, such as rolls or bread, during a baking process. The base material for a textile base body 3 (see Fig. 4) The baking base 2 is made of fiber or filament material, particularly in the form of aramid fibers 4. The aramid fibers or filaments 4 are made of para-aramid. The aramid fibers 4 are designed as a yarn with a staple length between 30 mm and 120 mm or as a continuous filament. The yarn is particularly a long-staple yarn. A medium-staple yarn, a short-staple yarn, or even a continuous yarn is also possible.

[0021] The textile base body 3 is in the form of a fabric with warp and weft threads. Fig. 2, Fig. 3 and 5 to 7 provide examples of possible weaves. The weave can be a plain weave, a leno weave, a waffle weave (cf. Fig. 5) to create a broken twill weave (cf. Fig. 6) or a twill weave (cf. Fig. 7), ribbed or panama weave.

[0022] The fabric can be designed in the form of a 3D fabric.

[0023] As an alternative to a woven fabric, the textile base body 3 can be in the form of a scrim, in the form of a braid, in the form of a knitted fabric or even in the form of a nonwoven fabric.

[0024] The uncoated textile base body 3 has a basis weight in the range between 50 g / m 2 and 250 g / m 2 .

[0025] 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.

[0026] The non-stick coating 5 is applied over the entire surface of the textile base body 3.

[0027] 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 based on PTFE.

[0028] 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.

[0029] The silicone material of the non-stick coating 5 is a grease-resistant silicone material.

[0030] The air permeability of the textile baking base 2, i.e. the textile base body 3, coated with the non-stick coating 5, is in the range between 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 / m2 / 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.

[0031] The air permeability of the textile baking mat 2 was tested on a TEXTEST FX 3300 LabAir IV device with a test area of ​​20 cm 2 and a test pressure of 200 Pa.

[0032] 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.

[0033] 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.

[0034] 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 .

[0035] The textile baking mat 2 has an identification marker 6 (cf. Fig. 1), which is supported by the textile base body 3. The identification marker 6 is an RFID chip. The RFID chip can be a thin, foil-like chip. Alternatively or additionally, a barcode or QR code can also be used as the identification marker 6.

[0036] The textile baking mat 2 is washable. Even after washing, the textile baking mat 2 retains its shape.

[0037] The textile baking mat 2 is food safe.

[0038] The textile baking mat 2, tested for crease recovery according to ISO 9867, has only a slight to negligible tendency to crease.

[0039] 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.

[0040] The supporting frame 7 is in the version according to Fig. 1 is designed as a supporting frame that completely surrounds the textile base body 3. The textile baking mat 2, and in particular the textile base body 3, is fixed to the supporting frame 7 via fastening means 8, which may be screws. Snap fasteners can also be used as fastening means.

[0041] 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.

[0042] 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 and are therefore not supported by any other component.

[0043] The textile baking mat 2 has a lower heat capacity than a baking tray, resulting in 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 mat 2 after baking.

[0044] 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.

[0045] 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. QUOTES CONTAINED IN THE DESCRIPTION
