Description

The invention relates to a rotisserie griller for grilling kebab, kebab, gyros or the like., With a vertically arranged grill spit and a tangentially arranged on substantially cylindrical or conical Grillgut heat source automatically to the grilling and with reference to the Grillgut is arranged pivotably and radially displaceable.

[State of the art]

Rotisserie grills are known in two designs. In one design, the rotisserie is arranged horizontally and is used for grilling poultry, rabbits, suckling pig or the like.

The other design is a vertically arranged rotisserie for grilling kebab, kebab, gyros or the like, in which a vertically arranged axis serves to receive the food. This axis is usually provided with a motor drive, which puts them in an axial rotational movement to slowly pass the skewered grilled food on a background heat source and fry it. After reaching a certain tan of the food to be cut with a knife or a cutter small strips from the surface of the meat body and offered for consumption. In the kebab production is made in this way from a conical body of meat, consisting of sandwiched skewered meat slices or pieces, a continuous cutting, always thinning meat body until the last meat is consumed.

In order to achieve a uniform distance between the food to be grilled and the heat source when removing the Dönerdurchmessers, the two ends of the spit are fixed in the known devices, that the position of the upper and lower Achslagerpunktes can be moved radially by loosening the movable detents. After repositioning of the spit and subsequent locking of the two Achslagerpunkte results in each case a different tangential position of the grill spit to the heat source. With the change of the position of the rotisserie the distance can be corrected continuously.

For other solutions, such as the DE 197 40 659 A1 , the position of the grill is not adjustable. Instead, the heat source is radially adjustable, so that an optimal distance to Grillgut can be adjusted.

In all previous solutions, the constant manual repositioning of the spit or the heat source when removing the diameter of the meat body is disadvantageous, because thereby an exact adherence to the distances is almost impossible and so an irregular browning of the food is achieved.

Furthermore, in the known devices of energy use is relatively high, as always a certain distance between grilled food and heat source must be maintained and a large part of the energy is withdrawn before reaching the grilling through a fume hood.

Another disadvantage is the unequal heat emission of the heat radiator with respect to its length.

OBJECT OF THE INVENTION

The object of the invention is to provide a rotisserie griller for grilling kebab, kebab, gyros or the like. That requires no control of proper positioning of grille and heat source, is economical in energy use and uniform cooking and browning over the entire length ensured the barbecue.

The object is achieved with the features of the first claim. Advantageous developments and refinements are the subject of the dependent claims.

The grill has a motor-driven grill spit and a tangentially arranged heat source, which is rotatable and pivotal in direct contact with the food to be grilled. The heat source consists of an oil-filled, cylindrical heating roller, in which an electrical heating element is arranged axially. The oil ensures a uniform heat dissipation of the heating roller to the food to be grilled over its entire length.

So that the heating roller does not stick with the food to be grilled, this is expediently provided with a non-stick coating.

Due to the direct concern of the heating roller to the grill good heat transfer is possible and the required temperatures can be lower compared to grills with fuel-powered and electric heat radiators, allowing a lower energy consumption.

[Example]

On the basis of a drawing, 1 , Is an advantageous embodiment of a rotisserie griller 1 described in detail as a kebab grill device.

In 1 is a vertically arranged and rotatably mounted grill spit 2 on which the grilled food 3 is arranged fixed in its axial and radial position. The spit 2 is powered by a motor and the motor puts him in a slow rotational movement about its longitudinal axis. The heat source for tanning the food 3 consists of a cylindrical heating roller 4 which are non-stick coated on their outside and about their longitudinal axis 16 is rotatably mounted.

The heating roller 4 consists of a closed at the bottom of the tubular cylinder, at its upper end an axle bushing is present. The longitudinal axis 16 is from a sleeve 5 formed, which is arranged concentrically within the tubular cylinder. At both ends of the cylinder is within the tubular cylinder each have a Achslagerung 7 (For example, ball bearings), in which, along the longitudinal axis 16 arranged sleeve 5 is stored.

At the top is the sleeve 5 guided by the axle bushing to the outside and there in an axle by means of a joint 17 in a sledge 11 hinged. The cylinder is thus in its longitudinal axis 16 rotatably arranged.

Inside the rigid sleeve 5 There is an electric heater 6 their connections 15 guided by the axle feedthrough to the outside. In the closed cavity of the heating roller 4 there is an oil filling 8th that the heat of electric heating 6 receives and forwards to the wall of the cylinder. The tubular cylinder, which is in direct contact with the food to be grilled 3 is located, this heat is in turn to the grilled food 3 from. To ensure a constant oil temperature, the heating is 6 via an adjustable thermostat 14 controlled.

So that the heating roller 4 a constant contact with the food 3 over the entire length, is the rotatable heating roller 4 radially displaceable and tangentially pivotable with respect to the food to be grilled 3 executed. This is the joint 17 the axle by means of a carriage 11 radially to the grill spit 2 movably arranged and is by the pressure force of a helical compression spring 10 permanently in the direction of the grill spit 2 pressed. The sled 11 moves on a slide rail 12 with the upper part of the grill 1 firmly connected and the movement of the carriage 11 radially limited. A helical spring 9 causes a tangential movement of the Heizwalzenlängsachse 16 and pivots the heating roller 4 in a circular arc in the direction of the spit 2 , wherein the pivot pivot point is at the upper end of the Heizwalzenachse. Both coil springs 9 . 10 thus cause a direct concern of the heating roller 4 over the entire length of the cylinder to the grill food 3 , Direct contact of the heating roller 4 with the grilled food 3 , puts the heating roller 4 by friction in a rotational movement about its own longitudinal axis 16 , wherein a direction of rotation of the heating roller 4 opposite to the direction of rotation of the grill skewer 2 results.

By continuously cutting small pieces of meat takes the diameter of the food 3 constantly off. The spring pressure of both coil springs 9 . 10 causes a continuous tracking of the heating roller 4 so that these are the direct contact to the grill 3 do not lose.
