AUTOMATIC DONER KEBAB SLICING MACHINE Technical Field

The present invention is related to automatic slicing machine that enables the products obtained by forming meat of chicken, veal etc. in a certain manner to be cooked and sliced automatically under the control of the user. The present invention is especially related to automatic doner kebab slicing machine, which enables the processes such as cooking doner kebab obtained after forming the meat of chicken, veal etc. in the shape of doner kebab, in maximum diameter, height and slope as much as desired and slicing thereof in desired thickness, to be determined by the user and to be performed automatically.

State of the Art

Today, many mechanisms where doner kebab slicing processes are performed are present. These create some problems while detecting the doner kebab meat, and hence performing the slicing. One of them is gauge slicing process. In the gauge slicing process, where doner kebab meat is detected, a gauge is used in the maximum size of doner kebab that can be sliced by the product getting closer to the doner kebab with a cutting knife and when said gauge contacts with doner kebab, slicing is performed on gauge plane and along the gauge. Here, slicing height is not equal to the doner kebab height and additional displacement is performed. That kind of slicing is appropriate for cylindrical doner kebabs and if doner kebab put during the first slicing process is conical or has roughness thereon, it cannot be sliced until the entire doner kebab surface is cylindrical. The non-sliced surfaces will be burnt during the second cooking process. In addition, the apparatuses are difficult to be cleaned because of their complexity.

Optic system, which is another system performing doner kebab slicing process and detecting doner kebab meat, includes optic sensors at both sides of knife mechanism that will perform the doner kebab meat slicing process. The position of doner kebab meat to be put between the sensors is detected and surface follow-up process is performed. Conical doner kebab can be sliced in said system; however, meat pieces hanging out of doner kebab surface cause the surface of doner kebab to be rough, in other words, to have many burrs, or as the meats put on slicing blade are detected as doner kebab surface by optic detector, surface follow-up cannot be performed on said areas. Therefore, the non-sliced surfaces are burnt during the second cooking process. One of the applications encountered in the search made in the literature with regards to the subject is the application numbered AU2008100850 and titled "meat slicing system". Said application is configured in order to slice the meat on a rotisserie around a longitudinal axis as gauge slicing process. Said meat slicing system comprises an arm. Said arm is mounted so as to rotate on a support and is positioned angular to the rotisserie. Said arm comprises a cutting end extending on a determined length and having a cutting track. Said cutting tradk extends longitudinal and parallel to the rotisserie and retains a cutting tool and allows the movement of cutting tool along the cutting track.

Another application relating to the subject is the one numbered WO2009085022 and titled "microcontroller controlled doner kebab meat broiler and cutter machine, operated by individual motion forms, with stepper motors and optical scanners". Said application is an optical system and is related to a machine recognizing the formed doner kebab. Said meat is cut by achieving different forms in terms of linear and angular position, speed, acceleration vector properties using optical detectors in determined periods.

In conclusion, improvements are made in doner kebab slicing systems and thus, new embodiments eliminating the above mentioned disadvantages and offering solutions for the present systems are needed.

Functioning principle of the invention;

The doner kebab rotisserie (15) is attached through the middle of formed doner kebab, is located at the doner kebab rotisserie lower bearing (23) and is fixed with doner kebab shaft upper fixer (7) provided on the doner kebab holder upper profile (6). The doner kebab rotisserie (15) is located into the doner kebab rotisserie lower balls (31 ) on the doner kebab rotisserie lower bearing (23) so as not leave any gap thanks to the conical shape of the bottom of doner kebab rotisserie (15) and to the grooves formed on the conical surface. It rotates idly on said bearing (23) in case of pulsed placement and prevents possible hits. The doner kebab rotisserie (15) is rotated together with doner kebab thereon without being displaced by rotating the doner kebab rotisserie lower bearing upper lid (32) via a wrench angularly with respect to the doner kebab rotisserie lower bearing (23) in case of electricity cut or any breakdown, and the doner kebab rotisserie (15) is enabled to rotate idly on the doner kebab rotisserie lower bearing middle ball (33) for manual slicing.

If doner kebab diameter is large, doner kebab bottom broad sheet (25) is put under the doner kebab and doner kebab is prevented from leaning downwards. The angle of burner (10) is adjusted via angle adjuster (1 1 ) and the distance thereof is adjusted via motion arm (12) in accordance with doner kebab surface. Again, burner wings (9) are adjusted in accordance with the size of doner kebab and the heat is directed to the desired area. The doner kebab follow-up apparatus (28) is located into the bearing (30) thereof by pulling the doner kebab follow-up apparatus montage pin (1). The circular knife (29) is located into the housing thereof and is fixed via fixing bolt (3) by closing the upper lid (4). The thickness adjustment of the knife is performed by means of rotating the thickness adjustment screw (27) and moving the knife (29) provided on the cutting unit (2).

The sliced doner kebabs are enabled to be stored and to remain hot and wet in the chamber thanks to the lid (24) closed on doner kebab meat covering tray (22). The sliced product can be accessed easily via upper lid (24) that is mobile in a back and forth manner and doner kebab piece sheet (21). The tray bottom burner (20) enables the sliced doner kebab meat to remain at desired temperature.

Upon issuing the command "slice", doner kebab follow-up apparatus (28) provided on arm unit (5) gets closer to the doner kebab. The apparatus (28) contacting with the meat surface performs angular motion without changing the distance between thereof and circular knife (29) rotating. Said motion is transferred to the detector thanks to the bearing (30) and read by the electronic system. Thus, the position of doner kebab is detected. The surface of doner kebab is followed up at the pressing force determined by the user via pressure adjustment button (18) and at the thickness again determined by the user, and is sliced by the rotating knife (29). When the power cable (13) provided on the main body (14) is attached and on/off button ( 7) is switched on, the system becomes ready for operation. The emergency button (19) is used in order to stop the system and cut the energy in case of emergency. Programing input (16) is used for software update. During cleaning of doner kebab burner (10), cleaning lid (8) is located so as to cover the top of the cores and cleaning chemical materials are prevented from damaging the cores.

In the preferred embodiments of the present invention, the gas-filled burner on the present invention can be in double-row (V type) and three-row, apart from a single row. The same variety can also be applied to electrical burners. As the diameter of doner kebab becomes smaller, doner kebab burner (10) can be made to get closer to the doner kebab automatically.

In another preferred embodiment of the present invention, doner kebab surface is recognized by heat sensor or sensors and start command can be issued for the slicing process automatically. The doner kebab rotisserie (15) can be rotated manually in case of any electricity cut or breakdown. The rotating motion of doner kebab can be determined by the user and the number of the balls (31 ) on the doner kebab rotisserie lower bearing can be changed.
