[0001] Tubular body as a carrier for grilled food

[0002] Description

[0003] The invention relates to a tubular body as a carrier for grilled food for rotisserie grills.

[0004] A dish commonly known as doner kebab, gyro, or schwarma contains grilled meat as its main ingredient, which is cooked on a usually vertically arranged rotisserie. For this purpose, large numbers of individual raw pieces of meat are skewered onto a tubular body until a roughly cylindrical or often truncated cone-shaped layer with a diameter of up to 50-60 cm is formed. This layer is then attached to a motor-driven rotisserie of the grill via the tubular body and rotated relative to a heating surface located a few centimeters from the layer. This creates a cooked layer of meat a few millimeters thick, which is then cut off the layer in portions using a cutting device and used for further processing.

[0005] Round or polygonal tubes made of aluminum, steel, or coated cardboard have been used as tube bodies to date. A disadvantage is that these tube bodies are not safe for human health. Aluminum, for example, should not be brought into prolonged contact with raw meat due to its proven toxicity. While steel and coated cardboard are not considered directly harmful, there is a risk that the cutting tool could come into contact with the tube body if the laminated body is almost completely used up. This can generate shavings from the tube body or the cutting tool itself (in the case of contact with metal tube bodies) and end up in the grilled meat.Based on this, the invention is based on the object of creating a tubular body as a carrier for grilled food that is harmless to health, suitable for consumption or compostable and inexpensive to produce.

[0006] To solve this problem, the combination of features specified in claim 1 is proposed. Advantageous embodiments and further developments of the invention emerge from the dependent claims.

[0007] According to the invention, the tubular body is made of a material based on grain flour or semolina. Such a material is harmless to health and even suitable for consumption or can be disposed of in an environmentally friendly manner as organic waste.

[0008] The material preferably contains cereal flour or semolina and water, as well as less than 10% by weight of egg, eggshell, and / or gum arabic as a binding agent. In particular, the material can contain 55-65% by weight of cereal flour or semolina and 35-45% by weight of water. As a grain, durum wheat is well suited to creating a tube body with sufficient mechanical strength.

[0009] The tubular body is preferably designed as a round tube or a polygonal tube, particularly a square tube. To improve the rigidity of the tube, the outer surface of the tubular body can be provided with grooves running parallel to its longitudinal center axis or with spiral grooves. A wall thickness of 1-10 mm and an outer diameter of 20-40 mm are practical for the tubular body, as are lengths of 30-100 cm.

[0010] Preferably, the tube body is manufactured cost-effectively using an extrusion process. This also allows for easy length measurement. In practice, it is also possible for the user to shorten an overly long tube body using simple means. The safety of the tube body under food regulations is further enhanced by pasteurization with hot steam. Tube bodies stored at room temperature can be used for at least one year.

[0011] The invention will be explained in more detail below with reference to an embodiment shown schematically in the drawing.

[0012] Fig. 1 a and b show a first embodiment of a grain-based tubular body with a round cross-section;

[0013] Fig. 2a and b a second embodiment of a grain-based tubular body with a square cross-section.

[0014] The tubular body 10, 10' shown in Fig. 1 as a carrier for grilled food for rotisserie grills based on a grain material has, as an extrusion product, an outer diameter of 25 mm, an inner diameter of 20 mm, and a wall thickness of 2.5 mm. The tubular body 10 has a smooth outer surface, while the tubular body 10' is provided on its outer surface with a plurality of ribs 12 that extend parallel to a longitudinal center axis of the tubular body. In principle, the tubular body can also be provided with any other surface structures that can be realized using an extrusion process.

[0015] The tubular body 14, 1' shown in Fig. 2 is made of the same material as the one shown in Fig. 1, but has a square cross-section with an outer edge length of 22 mm, an inner edge length of 16 mm, and a wall thickness of 3 mm. The tubular body 14 has a smooth surface, while the tubular body 14' is provided with a plurality of longitudinal ribs 16.

[0016] Both the tubular body shown in Fig. 1 and the one shown in Fig. 2 are compatible with all common rotisserie grills.
