    Field of the invention
    The invention relates to the general field of the food industry requiring a scraping instrument which operates in a cylindrical manner. This particularly concerns cylindrical pieces of cheese and chocolate whose consistency is variable, varying from medium-hard to hard. The instrument of the present invention generates the passage of a knife and this in a motorized manner on the surface of the food generating a scraping effect, forming a rosette of the food.
    The invention comprises a threaded rod which guarantees a uniform descent of the knife aesthetically generating beautiful rosettes.
    The invention also includes a system generating a reduction in the torque necessary to scrape the food, which allows the formation of rosettes fully automated and therefore without human intervention.
    State of the art
    The market has 2 classes of devices for scraping food as described briefly above, on the one hand there are completely mechanical systems which require manual scraping, that is to say by hand , and on the other hand there are the motorized systems.
    All mechanical systems as described in European patent applications EP 1 905 333 A2 and EP 0 081 466 A1. These systems consist of a stationary plate with a smooth cylindrical rod in the center around which a knife can turn by movement and manual force. A force pointing towards the base is manually applied so that said knife descends while exerting a circular movement which produces rosettes.
    In its "traditional" version, the device tray is in the form of a wooden disc of a certain thickness. The more modern versions often incorporate synthetic elements, in particular the circular base. Nevertheless, the technical condition is comparable from the point of view of its compactness and space as well as the operation to the "traditional" version.
    Any automated system, notably referring to the "Rosomat" (produced by Tête de Moine AOP), comprises a movable plate rotating the food around a central axis. The downward force necessary to make rosettes is provided by the user and is therefore difficult to control and is highly dependent on the user. Finally to generate the torque necessary to turn the food against the knife which is pushed down, an industrial motor is mounted under the circular disc which constitutes the base of the scraping instrument.
    Subject of the invention
    An object of the invention is to provide a motorized food scraper system, preferably in cylindrical form, and requiring a low torque and less power to obtain "rosettes" of food with good reproducibility, allowing a motorized chanterelle at low cost and low energy consumption.
    The present invention presents an alternative to existing motorized scraper systems which include a high torque industrial motor in addition to being energy intensive.
    Another object of the invention is to form these "rosettes" fully automatically and without force manually applied downwards. This is achieved by threading the central axis accompanied by a female part threaded inside the knife.
    A particular application of the invention consists in the production of rosettes of cheese or chocolate, in particular the head of a monk and without human intervention, apart from the location of the food to be scraped.

    Description of embodiments of the invention
    The present invention relates to a scraper device 1, also defined as a food scraper system, which is at least partially automated.
    Although a preferred application of the invention relates to the cheese field, it is not limited to scraping cheese. This invention relates to any food intended to be scraped and which is in the form of a block, preferably a cylindrical block. Said block is for example a cheese of the "Tête de moine" type or else chocolate. The details of the scraping system will be adapted according to the nature of the food to be scraped, as described below. Figure 9 illustrates different food blocks A, B.
    We refer here to the documents and website whose content is fully part of this application:<tb> - <SEP> EP 1 905 333 A2 and EP 0 081 466 A1;<tb> - <SEP> https://www.tetedemoine.ch/fr/;<tb> - <SEP> https://fr.wikipedia.org/wiki/T%C3%AAte_de_Moine.
    In its general form the scraper device of the invention 1 comprises a base 20 and a rod 12 and a knife 14 which is preferably secured to said rod 12. Said base 20 is arranged to receive an end 12b of said rod 12, and comprises a motorized mechanism 21 arranged to cooperate with said rod 12 so that, in operation, the rod 12 and said base 20 are put in relative rotation so that during each complete revolution, the knife descends in the direction of said base with a predetermined displacement. Several variants are included in the apparatus of invention 1:<tb> a) <SEP> the base 20 as well as the food block A, B can be fixed relative to the rod which is put into operation in rotation by said mechanism;<tb> b) <SEP> the base 20 can comprise mobile means, such as a rotary plate 23, in order to allow the rotation of a food block A, B relative to a rod 12 which is not subjected to rotation;<tb> c) <SEP> the base 20 can comprise a rotary plate 23 and a mechanism which can rotate the rod 12, the rod 12 and the rotary plate 23 being able to be rotated around a fictitious axis at rotational speeds different.
    There is shown in Figures 1 to 8 a preferred embodiment of the invention. FIG. 1 illustrates a view in 3 dimensions and FIG. 2 illustrates a section in a vertical plane of a scraping system of the invention.
    In the simplest form the invention consists of a plate 23 arranged at said base 20, this plate 23 being crossed by a rod 12 which is preferably an at least partially threaded rod. On this plate 23 is placed the food block. We see in Figure 2 that the set of gears 20a which move the plate 23 on which the food is placed. Figure 3 shows a section through a rotation mechanism according to the invention. FIG. 3 illustrates the motor 30 which moves the gears so that the rod 12 and the plate 23 rotate in the same direction. As illustrated in FIG. 6, the mechanism 20a of the apparatus of the invention can be mounted in a housing 21 which can be adapted in said base 20.
    In Figures 2-8, 7.8 it is clearly seen that the gears do not have the same dimensions. The ratio of the diameters of the gears is chosen so that the thickness of the resulting rosette is constant, for example 0.1 mm.
    In the case of cheese rosettes "Tête de moine" a thickness of 0.1mm was set as a preferred and optimal value giving beautiful rosettes. Other thicknesses are of course also possible for other types of cheese or food such as chocolate blocks. In carrying out the invention the number of teeth of a first gear 24 in Figure 2 and Figure 8 in is n2, the number of teeth of a second gear 22 shown in Figure 2 and 8 is n1. The number of teeth of a third gear 26 shown in Figure 2 and 8 is n4 and finally the number of teeth of a fourth gear 28 shown in Figure 3 and 8 is n3. The preferred numerical values respectively: n1 = 15, n2 = 40, n3 = 10 and n4 = 100. The central rod 12 is threaded, in a preferred embodiment, with a pitch M8, and has a corresponding part (threaded with a pitch of M8) which carries the knife 14. This means that if the rod makes 1 turn around it- even as the knife goes down 0.5mm. By turning the plate on which the cheese rests, the descent of the knife towards the cheese is multiplied by a factor R, defined by R = (n1 / n2) * (n4 / n3) which gives in this case copy R = 5. For R = 5 we can therefore obtain a rosette with a thickness of 0.5mm / 5 = 0.1mm.
    In one embodiment the system 1 can be adapted to vary the speed which does not necessarily have to be uniform during the scraping.
    In an advantageous embodiment the gear system can be modified so that said rod and the plate rotate in opposite directions and / or at different rotational speeds.
    In an exemplary embodiment of the mechanical and electrical means can be adapted to the scraping system in order to measure the forces applied during the scraping and to adapt the rotation speed accordingly, see the support forces. It is understood that in one embodiment, the system may include a modification of cogwheels before or during the scraping operation, similar to the change of cooperation of cogs in a gearbox.
    In one embodiment, illustrated in Figure 9, a system 1 'may include at least two systems 1a, 1b scraping as described before. The said at least two scraping systems 1a, 1b can be different systems as illustrated diagrammatically in FIG. 9. Thus, a system can comprise a single plate and at least two motorized systems. FIG. 9 illustrates the principle of a system 1 'comprising a central mechanism 30' which actuates each of the knives 14a, 14b of the two scraping devices 1a, 1b of said system 1 '. This can be useful when a large number of scraper rosettes are to be produced. In a variant, a system 1 can comprise several scraping systems each having their own motorized system. In another variant, the system 1 of the invention can be adapted so that a single motorized block actuates several scraping systems preferably fixed on a single base.
    In one embodiment, the scraping system 1 may include means which make it possible to remove the rosettes produced without the keys. For example, a mechanical system can be adapted to a scraping system so that the rosette has come out of the scraping surface. This can be done by various means, the following examples are not limiting. In one example, the rosette can be gripped by a pinching mechanism at the end of the scraping process and this mechanism can move and transfer the rosette to a container provided for this purpose. Said displacement and transfer can also be achieved by techniques using at least a portion actuated by compressed air and / or a partial vacuum technique. Not handling a rosette manually can be an advantage if a consumer does not want the rosettes to be handled by the hands of an operator.
    In a variant, the conditions of speed and applied force can be adapted in order to produce rosettes of particular shapes, textures and edges. A manual system would not allow such force and speed control to be achieved in order to produce such predetermined shapes.
    It is also understood in the invention the possibilities of exchanging the scraping knives 14 of the system 1. Thus, the system 1 can be adapted so that, as a function of certain parameters such as the shape or the thickness or the desired volume of the rosette, system 1 can choose and place a knife of a particular shape. In a variant, said knife 14 can be replaced manually or the system can be designed to present a new knife for the scraping operation. In an exemplary embodiment, p illustrated in FIG. 9, a knife 14 can comprise at least two portions whose scraping edge is different and the system can be designed to move the knife radially in order to present one of said two facing portions on the surface of the food to be scraped off. It is also understood that a knife 14 need not necessarily have a uniform cutting edge but can be structured as illustrated in FIG. 9.
    In variants, the system may include means for subjecting the knife 14 to vibration during scraping. This can be useful in order to avoid blocking the rotation mechanism 20a during the scraping operation.
    Also, in one embodiment the system may include sensors or actuators. For example, the system 1 may include means for measuring force in order to capture the hardness of the surface to be scraped, which makes it possible to better adapt the scraping parameters of the machine such as the vertical force applied and / or the speed of rotation and / or displacement in the direction of the central axis for each rotation.
    In variants, the system 1 may include a system for detecting the color and / or the texture of the surface. Such a variant can be used in order to improve the determination of the area for the end of scraping of the block. The detection system can include at least one light source and an integrated image sensor and / or mini spectrometer. Such a more sophisticated pigging system can be useful in a laboratory environment to help improve the performance and choice of parameters of the pigging machine.
    In a variant, the scraping system 1 can be adapted and may include a reservoir intended to include several blocks of food to be scraped, and include a mechanism which grasps the blocks and automatically transmits them on said axis of rotation. The mechanism can also be adapted to automatically remove the bottom of the block at the end of the scraping operation.
