[0001] DONER KEBAB STRETCHING MACHINE

[0002] Technical Field

[0003] The invention relates to a machine used in the stretching process of doner kebab products made with red meat or white meat in the food industry.

[0004] The invention particularly relates to a doner kebab stretching machine that enables the conical shaped doner kebab to be wrapped with stretch in accordance with its angular form.

[0005] The State of Art

[0006] In the food sector, doner kebab is a type of food obtained by cooking pieces of red or white meat on a skewer by hanging them vertically on a doner kebab cooking machine via a skewer and rotating them in front of a fire.

[0007] In the production of doner kebab, which is commonly cooked in restaurants and diner (cook shop) in the food industry, after the meat pieces are placed on skewer, the doner is wrapped with stretch to protect it from external factors and to be transported until the cooking process. In present applications, doner kebab stretching machines are used to wrap the doner kebab with stretch. In the doner kebab stretching machines in the state of art, the slide system that performs the stretching process cannot detect the angle of the conical doner and therefore it is not possible to perform the stretching process properly. In some cases, the doner kebab is laid on its side to obtain the appropriate angle for stretching. However, in this case, the doner kebab made of minced meat or meat may spill on the ground and be wasted when the doner kebab is turned while being stretched. For this reason, in the state of the art, there was a need for a machine to ensure the proper stretching of the conical doner kebab.

[0008] In the research carried out in the literature, document numbered TR2012 / 09417 can be shown as an example to the state of the art. Said document relates to a doner kebab cooking device having movable cooking wings, which will allow fast, economical and delicious doner cooking in diners, restaurants and similar food production areas. Said device basically consists of two movable wings that have a curved structure to surround the doner meat fixed on a cooking skewer, various resistances that are positioned inside the movable wings, and two connection poles to which the electrical resistances are fixed.

[0009] In the research carried out in the literature, document numbered TR2022 / 018201 can be shown as another example to the state of the art. Said document relates to a radiant-free gas cooking device that provides increasing of gas combustion efficiency, especially in doner kebab stoves, for use in the entire food industry. Said device basically comprises a ventilation apparatus with at least one fan that provides air and gas circulation, at least one firing card that enables firing timing to be adjusted, at least one proportional valve provides adjusting the ratio of gas mixture entering through the air and venturi channel positioned between a firing card and at least one venturi channel, at least one venturi channel that is positioned behind said ventilation apparatus and ensures the mixing of air and flammable gas in it, at least one flexible fabric that provides firing and on which at least one electrode is positioned, at least one combustion head comprising a flexible fabric, which is a metal knitted cloth that can withstand high temperatures.

[0010] Both devices mentioned above are for cooking doner kebab and cannot be used for wrapping the doner kebab with stretch during its production.

[0011] As a result, the existence of the above problems and the inadequacy of existing solutions have required a development in the relevant technical field.

[0015] The main of the invention is to present a doner kebab stretching machine that enables the stretching process to be carried out properly by calculating the conical angle of the doner kebab and eliminates the spilling problem of minced meat or meat during the stretching process.

[0016] Another object of the invention is to present a doner kebab stretching machine that allows the doner to be wrapped tightly at the desired tension with increasing force in each rotation by means of the torque control.

[0017] In order to fulfill all the objects that are stated above and can be derived from the detailed description, the invention is a stretching machine used in the stretching process of doner kebab which is made with red meat or white meat in the food industry, and comprises the following: a chassis that is positioned on the ground, a doner table that carries the doner kebab by making a rotating movement on the chassis, a pressure plate that allows the doner kebab to rotate by applying pressure to the doner on the chassis, a stretch holder that carries the stretch on the chassis, a sensor at the front of the stretch holderthat calculates the angle of the conical doner kebab, an angled slide system that is positioned on the chassis by moving up and down according to the angle information coming from the sensor, an engine that moves the angled slide system on the chassis, a stretch wrapping mechanism that wraps the stretch around the doner kebab on the stretch holder.

[0032] Detailed Description of the Invention

[0033] In this detailed description, the preferred alternatives of the stretching machine (A), which is subject of the invention are described only for a better understanding of the subject and in a way that does not form any limiting effect.

[0034] In Figure 1 , it is given a general view of the stretching machine (A), which is subject of the invention. According to this, the stretching machine (A) comprises the following in its most basic form; a chassis (10) that is positioned on the ground, a doner table (20) that carries the doner kebab (D) by making a rotating movement on the chassis (10), a pressure plate (30) that allows the doner kebab (D) to rotate by applying pressure to the doner kebab (D) on the chassis (10), a stretch holder (40) that carries the stretch on the chassis (10), a sensor (50) at the front of the stretch holder (40) that calculates the angle of the conical shaped doner kebab (D), an angled slide system (60) that is positioned on the chassis (10) by moving up and down according to the angle information coming from the sensor (50), an engine that (70) moves the angled slide system, a stretch wrapping mechanism (80) that on the stretch holder (40) which is wraps the stretch around the doner kebab (D), a screen (90) that is located on the chassis (10) and allows manual entry of the conical shaped doner kebab (D) angle.

[0035] There is a doner table (20) that rotates on the chassis (10), which forms the main structure of the stretching machine (A), which is subject of the invention. The said doner table (20) carries the doner kebab (D) by making a free rotation movement. There is a pressure plate (30) on the chassis (10) that allows the doner kebab (D) to rotate by applying pressure force to the doner kebab (D).

[0036] The stretch wrapped on the doner kebab (D) is held by the stretch holder (40) located on the chassis (10). At least one sensor (50) is positioned on the chassis (10), at the front of the stretch holder (40). The said sensor (50) calculates the angle of the conical shaped doner kebab (D). There is an angled slide system (60) on the chassis (10), which is positioned by moving up and down according to the angle information coming from the sensor (50). The up and down movement of the angled slide system (60) is provided by at least one engine (70) located on the chassis (10).

[0037] In an alternative embodiment of the invention, there may be at least one screen (90) on the chassis (10). The said screen (90) can allow the user to manually enter the angle (D) of the conical shaped doner kebab (D).

[0038] On the stretch holder (40), there is a stretch wrapping mechanism (80) that wraps the stretch on the doner kebab (D). The said stretch wrapping mechanism (80) also adjusts the stretch tension by means of the torque control system. Thus, the tension of the stretch is increased and it is provided that the doner kebab (D) is tightly wrapped with stretch.

[0039] The working principle of the stretching machine (A), which is subject of the invention is as follows;

[0040] The doner kebab (D) is placed on the doner table (20) and the doner kebab (D) starts to rotate by applying pressure on the doner kebab (D) from above with the pressure plate (30).
