TECHNICAL AREA

The present invention relates to a device for scraping cheese slices from a piece of cheese.

STATE OF THE ART

Facilities for scraping cheese slices from a piece of cheese are marketed by Metafil-laGirolle AG, 2718 Lajoux, Switzerland under the name "Girolle" and are shown inter alia in EP 0 081 466 A1 and EP 1 905 333 A2.

The piece of cheese is placed on a holding plate and then the upper side thereof is scraped off with a knife, which is rotated with its cutting edge pointing downwards around the center of the piece of cheese, to produce the cheese slices.

The guidance of the knife and the stabilization of the piece of cheese on the holding plate is taken over by a guide mandrel passing centrally through the piece of cheese or guided in a tripod centrally into the top of the cheese piece over the top of the piece of cheese, from which the knife moves radially extends outside. The cheese slats obtained with these known devices, however, in the edge region, which is formed by scraping the cheese surface in the region of the center of rotation of the knife, with respect to their structure undefined and crumbly and therefore in need of improvement.

PRESENTATION OF THE INVENTION

It is therefore the task of a device for scraping cheese slices of a piece of cheese to provide, which does not have the aforementioned disadvantages of the prior art, or at least partially avoids.

This object is achieved by the device according to claim 1.

Accordingly, the invention relates to a device for scraping cheese slices of a preferably barrel-shaped piece of cheese. Cheese slices here are thin, flaky structures or chips made of cheese, which are formed when scraping cheese from the surface of the piece of cheese and usually roll up into rosette-like structures, which is why these cheese slices are often referred to as "rosettes" A distinction is made between the cheese slices of cheese slices, which are obtained by cutting off a layer from a piece of cheese and undergo virtually no structural change.

The device comprises a preferably circular on ahmeplatte with a preferably substantially flat, upwardly facing receiving surface for receiving the cheese piece to be scraped. The receiving plate is rotatably mounted about a vertical, perpendicular to the receiving surface axis of rotation in a fixed during normal operation basic structure, which is preferably formed by a closed housing and also has drive means for rotating the receiving plate about its axis of rotation around. As a driving means are both manually betägtigbare drive means, such as. a hand crank with deflection gear, as well as foreign energy-actuated drive means, such. an electric motor, provided.

Furthermore, the device comprises a blade with a cutting edge for scraping the cheese slats from the top of the cheese on the receiving surface of the receiving plate and rotated with this during normal operation. It is the Blade placed or placed over the receiving surface in such a way that its cutting edge in operation substantially perpendicular to the axis of rotation or parallel to the receiving surface of the receiving plate and the axis of rotation of the receiving plate thereby cuts. The cutting edge of the blade thus extends to the axis of rotation of the receiving plate.

Furthermore, the device comprises a pressing member, which is placed or placed over the receiving surface such that the cheese piece can be pressed against the receiving surface of the receiving plate during the appropriate scraping of cheese slats from the upper side, with the effect that the cheese piece is pressed on the receiving plate is stabilized.

By the inventive device for scraping cheese slices, wherein the surface of the

Cheese piece is scraped to the center of rotation, it is possible to obtain in terms of their shape and structure optimal cheese slices.

In a preferred embodiment of the device, the cutting edge of the blade is rotatably guided in the intended operation relative to the rotational axis of the receiving plate but along this, whereby the scraping speed is determined solely by the rotational speed of the receiving plate and a structurally simple structure is possible.

In principle, however, it would also be conceivable additionally to rotate the blade about an axis of rotation extending parallel or at a particularly right angle to the axis of rotation of the receiving plate, thereby additionally influencing the scraping speed.

In a further preferred embodiment of the device, the blade has on the side on which the cheese slices are scraped off the cheese piece during normal operation, an outer surface, which extends from the cutting edge substantially vertically upwards. This can the structure of the obtained cheese slices can be further improved.

In yet another preferred embodiment of the device, the receiving surface of the receiving plate is formed in relief or provided with projecting driving elements. This makes it possible to produce a positive connection between the piece of cheese and the receiving plate during operation and thus reliably prevent a relative movement between the receiving plate and the piece of cheese, which can lead to a standstill of the cheese in operation.

In yet another preferred embodiment of the device, the pressing member is designed such that it has at least one pressing surface for pressing against the upper side of the cheese piece, which in the intended operation is non-rotatable relative to the axis of rotation of the receiving plate but slidable along it, so that the pressing surface when the cheese piece is pressed against the receiving surface of the receiving plate as intended, it slides on top of the piece of cheese. Preferably, the Andrückorgan exactly one, substantially flat pressing surface.

As a result, a conceivable simple and easy-to-clean construction of the device can be achieved.

Also, in the aforementioned preferred embodiment, it is advantageous that the pressing surface is formed of a material having a lower friction coefficient with respect to a piece of cheese, more preferably than a piece of cheese of the Tete de Moine type cheese, as the material containing the cheese

Receiving surface of the receiving plate forms. For this purpose, the at least one pressing surface is preferably provided with a non-stick coating, preferably made of Teflon. As a result, the danger of a relative movement between the receiving plate and the piece of cheese during normal operation can be further reduced. In yet another or alternative preferred embodiment of the device, the pressing member has at least one, preferably conical pressure roller for pressing against the top of the cheese piece during normal operation. The rotation axis of the pressure roller is non-rotatably in the intended operation with respect to the axis of rotation of the receiving plate but slidably along the same, so that this pressure roller unrolls when pressing the cheese piece on the top.

Advantageously, the device has at least two, preferably exactly three, pressure rollers, which are preferably arranged relative to one another such that their axes of rotation form uniform angles relative to one another in the direction of the axis of rotation of the mounting plate.

By using pressure rollers for pressing the piece of cheese to the receiving surface of the receiving plate, the torque to be transmitted from the receiving surface to the piece of cheese can be reduced substantially to the moment required for peeling the cheese slices, thereby increasing safety against a relative movement between the receiving plate and the cheese piece can be further increased during normal operation.

In yet another preferred embodiment of the device, the blade is fixedly connected to a component forming the at least one pressing surface or to a component of the pressing member carrying the at least one pressure roller, preferably in such a way that the cutting edge of the blade overlies this pressure surface or Pressure roller protrudes. This makes it possible in a simple manner to keep the thickness of the peeled cheese slats constant by manual pressing.

In yet another preferred embodiment of the device, the pressing member is disposed above a guide plate arranged next to the receiving plate connected to the basic structure, such that it is rotatably guided during the intended operation with respect to the rotational axis of the receiving plate but slidably along the same or feasible. This construction ^¬ principle allows a compact design of the device according to inventiveness.

It is further advantageous that the pressing member for facilitating the placement of a piece of cheese on the receiving surface of the receiving plate from an operating position in which it is placed as intended on the receiving surface of the receiving plate to allow pressing a cheese piece, in a non-operating position, in which it releases the area above the receiving surface, is pivotable, preferably around a vertical or horizontal pivot axis around. In addition to the simple loading of the device with a piece of cheese, this embodiment also offers the possibility of "parking" the pressing device when not in use of the device in the area next to the receiving plate.

In yet another preferred embodiment of the device, the pressing member is the only device for stabilizing the cheese piece during the intended scraping of cheese slats. As a result, a simple and easy-to-clean construction of the inventive device is favored.

In another preferred embodiment, the device comprises guide means for laterally guiding a barrel-shaped piece of cheese arranged on the receiving surface during normal operation during scraping of cheese slats.

It is preferred that the guide means comprise one or more guide surfaces or guide rollers which can slide or roll along the outer circumference of the barrel-shaped piece of cheese during normal operation, it being preferred that these Guide surfaces or guide rollers are formed or carried by the Andrückorgan.

Such guide means help to stabilize the tonnenförrige cheese piece during the intended scraping of cheese slats, in addition to stabilization by the pressure surfaces and / or pressure rollers of Andrückorgans.

WAYS FOR CARRYING OUT THE INVENTION

Fig. 1 shows an inventive device for scraping cheese slats obliquely from the front in a non-operating state. FIGS. 2a and 2b show the same device with a tonal cheese piece 1 arranged thereon in an operative state, once obliquely from the front (FIG. 2a) and once obliquely from the rear (FIG. 2b).

As can be seen, the device has a housing 4 which serves as a basic structure that complies with the requirements, in which a circular receiving plate 2 is rotatably mounted about a vertical axis of rotation D. Arranged in the housing 4 is an electric motor (not visible) for rotating the receiving plate about its axis of rotation D. The electric motor can be powered by a pressure Switch 11 can be activated. The receiving plate 2 has an upwardly facing receiving surface 3, on which a barrel-shaped piece of cheese 1 of the type of cheese "Tete de Moine" is centrally arranged in Figures 2a and 2. As can be seen in Figure 1, the receiving surface 3 is six provided radially inwardly and upwardly extending driving wings 14 from the rotation center of the receiving plate 2, which in operation produce a positive locking in the direction of rotation between the receiving plate 2 and the cheese piece 1. The receiving plate 2 is surrounded by a tray 17 which encloses the housing 4 This tray 17 serves to catch any crumbs falling off when scraping from cheese slices.To be able to remove these crumbs in a simple manner, the tray 17 can be drawn laterally under the receiving plate 2 and from the device will be removed.

Further, the device comprises a pressure plate 7, which 'forms on its underside a single continuous flat pressing surface, with which the cheese piece 1 can be manually pressed in the situation shown in Fig. 2 against the receiving plate 2, to stabilize the same during the scraping of cheese slats during normal operation. In the non-operating situation shown in FIG. 1, the pressure plate 7 is positioned next to the receiving plate 2.

As can also be seen, the pressure plate 7 has a blade holder 5, which carries a blade 13 with a downwardly over the pressing surface above cutting edge 6, for scraping the cheese slats during normal operation of the device from the top of the receiving surface 3 of the receiving plate In the operative situation shown in FIGS. 2a and 2b, the cutting edge 6 extends perpendicular to the axis of rotation D of the receiving plate 2 and cuts this axis of rotation D thereby. On the side on which the cheese slices are scraped off the piece of cheese 1 during normal operation, ie in the present case on the side facing away from the blade holder 5, the blade 13 has an outer surface 8 which extends vertically upward from the cutting edge 6 extends.

In order to enable the intended operation and the optional placement of the pressure plate 7 in the non-operating position shown in Fig. 1, the device has two fixedly connected to the housing 4 and next to the receiving plate 2 upwardly projecting guide columns 9, 10, with which the pressure plate 7 in the operating state shown in Figures 2a and 2b rotatably relative to the rotational axis D of the receiving plate 2 but slidably guided along this axis of rotation D.

In this case, the first guide column 9, which is larger in diameter and longer in extent than the second guide column 10, together with a arranged on the pressure plate 7 bearing bush 12, the actual longitudinal guide of the pressure plate 7, while the second guide column 10 during normal operation a hole 15 passes through in the pressure plate 7 and serves only as an abutment against rotation of the pressure plate 7 about the first guide column 9 around and thus the securing of the rotationally fixed state with respect to the axis of rotation D of the receiving plate. 2

In order to scrape cheese slices (rosettes) from the piece of cheese 1 as intended, the user in the situation shown in Figures 2a and 2b presses with one hand from above on the pressure plate 7. With the other hand he presses the pressure switch 11, whereby the receiving plate 2 with the Cheese slices 1 arranged thereon are set in rotation and scraped with the blade 13 cheese slices from the top of the cheese piece 1. As soon as the user releases the pressure switch 11 again, the rotation stops and the user can remove the cheese slices accumulated in front of the blade 13.

In order to bring the pressure plate 7, starting from the operative situation shown in FIGS. 2a and 2b, in which it is placed as intended above the receiving surface 3 of the receiving plate 2, into the inoperative situation shown in FIG. until the second guide post 10 emerges completely from its bore 15. Subsequently, the pressure plate 7 is rotated with its guide sleeve 12 about the longitudinal axis S of the first guide column 9 around and then lowered next to the receiving plate 2 on the housing 4.

To bring the pressure plate 7 starting from the operative situation shown in Figures 2a and 2b in the rest position shown in Fig. 3, in which it is usually placed when the cheese piece remains on the receiving plate 2 but temporarily scraped no cheese slats be, the pressure plate 7 is raised until the second guide column 10 completely emerges from the bore 15 in the pressure plate 7. Then, the pressure plate 7 is rotated with its guide sleeve 12 about the longitudinal axis S of the first FU insurance column 9 around until a arranged in the pressure plate 7 centering hole 16 is positioned over the second guide post 10. Subsequently, the pressure plate 7 is lowered. Since the second guide column 10 is formed pointed or stepped at its upper end, such that it can enter a piece in the center hole 16 before it rests axially on the boundaries of the center hole 16, the pressure plate 7 is located after lowering positively centered on the upper end of the second guide column 10. In this situation, it is located above the piece of cheese 1 and exposes the top thereof.
