Description

The present invention relates to a method and a device for molding food products, exhibiting at least one embossed imprint, appearing in hollow form and / or in the form of a recess and / or a device for molding food products with embossed fingerprints, especially in bakery, pastry and bakery. or projecting, especially in the bakery, pastry, biscuit, and other food trades.

The method and the molding device according to the invention are intended to propose a custom marking technique for food products, in particular bakery, pastry and biscuit, by the positioning of supports, which can be removable, and in relief, recessed and / or protruding, in molds used for the molding of food products, in all trades of mouth. The general object of the present invention is to allow customization of molded food products, and in particular molded products of bakery, pastry and biscuit, on the bottom and / or around molds, rigid or flexible, used in this type of mold. 'industry. Indeed, there is a strong expectation of professionals of the food trades, and in particular the bakery, pastry and biscuit, to be able to customize the finished products, such as breads, cakes, biscuits and pastries, with a marking in relief (hollow and / or projecting) desired by the consumers of these finished products and / or by the professionals who market them.

By the French patent 2,759,250, there is already known a baking mat having raised asperities, to obtain decorative patterns for pastry or confectionery.

Such a cooking mat of food products, made of a material that does not adhere to foodstuffs, such as silicone or fluoropolymer that can be supported or associated with a foam material, plastic, or fiberglass or metal, is remarkable in that it has, on the surface, reliefs able to provide different decorations on the food product considered. This type of embossed carpet, which is also in the form of sheets of composite materials or polymers resistant to high cooking temperatures (up to about 300 ° C) generates a print on the food product that is cooked on the carpet. In particular, such a relief mat can achieve, on cooked food products, detailed markings, which can not be obtained with stamped molds having fingerprints included in the mold structure. The problem underlying the present invention is to meet the expectation presented above of the professionals of the oral industries, and in particular the bakery, pastry and biscuit, by proposing a method and a molding device of food products having at least one relief imprint (recessed and / or protruding) to allow them to customize finished food products, such as breads, biscuits, pastries, cakes, according to a relief mark desired by said manufacturers and / or their customers.

For this purpose, the method of molding food products having at least one relief imprint, appearing hollow and / or protruding, according to the invention, especially in the bakery, pastry, biscuit and other food trades, is characterized in that it comprises the steps of: disposing, removably or permanently, at least one positioning interface, in the form of a plate or sheet, or glue film, and at least one food grade material, inside of a mold, rigid or flexible, fixing, removably or permanently, on said positioning interface at least one molding insert having at least one embossed recess, appearing hollow and / or protruding, in its face turned towards the volume inside said mold, introducing into said mold at least one food product to be molded up to cover said molding insert, carrying out a molding operation, whereby said food product is subjected to end en masse in the mold, and demolding the resulting molded product, which has, in its portion having been in contact with said embossed print of said molding insert, a raised mark, appearing protruding and / or recessed, of shape at least in part complementary to that of said raised relief, appearing hollow and / or projecting, said molding insert.

With regard more particularly to the bakery, pastry and biscuit industry, the method of the invention is advantageously further characterized in that it consists in introducing into said mold a bakery, pastry or biscuit dough, to bake said dough in the mold, wherein has previously disposed at least one positioning interface and at least one molding insert made of one or more materials resistant to the molding temperature. However, the method of the invention is not limited to moldings requiring a firing or heating step, the molding being able to result from a gelling step, OR generating a setting of the weight of the food product or products introduced into the mold, by any other physicochemical phenomenon, in particular freezing.With or without a cooking step, or more simply heating, the method of the invention may consist of disposing, removably or permanently, at least one positioning interface on the bottom mold, and / or dispose, removably or permanently, at least one positioning interface on the inner face of a side wall of the mold. In the latter case, it is obvious that the implementation of the method of the invention is more favorable to the use of a flexible mold rather than a rigid mold, to promote demolding. In the case of permanent fixing of a positioning interface in a mold and / or of a molding insert on a positioning interface, the interface may itself be constituted by a layer of adhesive, fixing the molding insert in the mold. The invention also relates to a device for molding food products having at least one embossed impression, appearing in a hollow, in particular in a bakery, a biscuit shop, for projecting and / or baking, and the method according to the invention. invention and as presented above, the molding device being characterized in that it comprises: - at least one positioning interface, substantially in the form of a plate or sheet, in at least one food grade material, and adapted to be arranged, removably or permanently, inside a mold, rigid or flexible, against the bottom and / or a side wall of said mold, - at least one molding insert, also in at least one food grade material , capable of being retained, removably or permanently, on said positioning interface, and having a relief imprint, appearing hollow and / or protruding, in a face of said insert which is turned to the interior of said mold. In the case of a positioning interface permanently fixed in the mold, the interface may be a fixed bonding interface, itself made by a layer of glue.

So that the device of the invention is suitable for use in bakery, pastry and / or biscuit, said positioning interface and / or said molding insert is or is thermally stable (s) with a temperature of about - 40 ° C at a temperature of about + 300 ° C, so as to allow not only molding by heating and baking, but also moldings, for example by gelling, freezing / freezing, from liquid food products poured into the mold or for the preservation operations, possibly after growth or fermentation of bread dough, cake or biscuit.

In the various applications of a molding device according to the invention, said positioning interface and / or said molding insert is or are made of one or more materials chosen from metallic materials, ceramics, polymers, composites, in particular synthetic resin matrix reinforced by a reinforcement of organic or inorganic fibers, and synthetic, especially high temperature resistant polymers and silicone elastomers. In addition, and more particularly for applications involving molding with a cooking or heating step, said positioning interface has a sufficiently high thermal conductivity, so that the interface does not constitute a heat shield opposing the heat transfer between the mold and the food product (s) to be molded. In the case of a removable attachment of a positioning interface in the mold and / or at least one insert on said interface and to promote the introduction and removal of any positioning interface in the mold , against the bottom or a side wall thereof, and / or the removable attachment of any molding insert on any positioning interface, it is advantageous that said positioning interface is bondable and peelable on the mold and / or on said molding insert. Alternatively, or cumulatively, said molding insert can be removably attached to the mold and / or said at least one positioning interface by at least one permanent magnet.

Finally, the subject of the invention is a food product molding assembly having at least one embossed, recessed and / or protruding impression, said assembly being characterized in that it comprises at least one mold, rigid or flexible, and a molding device according to the invention and as presented above. A decisive advantage of the device and the molding assembly according to the invention is that the fixing, preferably removable but may be permanent, of any molding insert on any positioning interface, and the provision, preferably removable but can being permanent, any positioning interface in the mold can customize the productions, without necessarily changing the mold in case of removable attachment, but by changing more simply insert molding and / or positioning interface, so that the device and the molding assembly according to the invention provide a great versatility and great freedom of marking food products, by associating, in the same mold, one or more positioning interfaces, at least one of which is more specifically intended to be arranged on the bottom of the mold, and at least one other is more specifically intended to be removably retained on a wall lateral mold, the positioning interface or each of them being able to maintain in a defined position relative to the mold at least one, but advantageously several interchangeable molding inserts, each of which can be fixed removably on one or each positioning interfaces. Other features and advantages of the invention will emerge from the description given below, without limitation, of an exemplary embodiment described with reference to the accompanying drawings, in which: FIG. 1 is a perspective view of a example of mold, flexible or rigid, on the bottom of which is preferably removably disposed a positioning interface, on which is, preferably removably, fixed a molding insert having two patterns in relief, projecting inwardly of mold in this example, but one of which may project inwards from the mold and the other recessed in the insert, in a second example, or both of which are recessed in the insert, in a third example, not shown for simplicity; Figure 2 is an exploded perspective view of the molding assembly of Figure 1; Figure 3 is a diametrical sectional view along the line III of the molding assembly of Figure 1; and FIG. 4 is a perspective view of a cake molded in the molding assembly of FIGS. 1 to 3, the top of which, after demolding, has two recessed markings having shapes complementary to the shapes of the two cavities. projecting relief of the molding insert of the assembly and the molding device of Figures 1 to 3, the two markings of the cake can be one recessed and the other protruding or both projecting on the above the cake, respectively in the case of the insert according to the second and third examples mentioned above in the presentation of Figure 1. The example of molding assembly with at least one relief imprint according to the invention and as shown in FIGS. 1 to 3 comprises a mold 1 and a molding device 2 with at least one embossed imprint, which is capable of being positioned, preferably removably, in the mold 1, for a mold molding operation. one or more products has foodstuffs, for example a dough of bread dough, or a cake or biscuit dough, which requires a baking in the mold 1. The molding device 2 itself comprises at least one positioning interface such as 3, and at at least one molding insert such as 4, having at least one relief imprint (projecting and / or recessed), and, in the illustrated example of the molding insert 4, two embossed imprints 5 and 6, appearing protruding outwards (towards the top) of the insert 4. In this example, the mold is a generally frustoconical baking mold, with a circular disc bottom 7, with a frustoconical lateral wall 8, flared from the bottom 7 to a flat and peripheral annular rim 9 at the upper end of the side wall 8. Of course, many other mold geometries 30 can be envisaged (molds with an oval, rectangular or square cross-section, or having another polygonal shape, and / or mold with central chimney e for example).

The mold 1 may be a rigid mold, metal, food grade, for example stamped sheet of stainless steel, aluminized steel or an aluminum alloy, all coated with a non-stick coating or not . Such a metal mold is able to withstand cooking temperatures above 300 ° C and temperatures below -40 ° C, allowing its use for freezing / freezing operations. Alternatively, the mold 1 may be a flexible mold, of the type described for example in patent document WO 2009/147344, and made of a flexible, self-supporting, non-adherent membrane that may be alveolated, forming a food preparation mold, in particular for baking, pastry, pastry and biscuit making, in particular for molding, fermenting and baking bread-making pastes, and which comprises a composite structure comprising a silicone rubber matrix consisting of at least one elastomer or at least one silicone resin, and reinforced by a textile structure reinforcement consisting of son and / or inorganic and / or organic fibers. Such a flexible, food grade mold also supports baking temperatures up to about 300 ° C, and negative temperatures up to about -40 ° C, suitable for freezing / freezing operations. The positioning interface 3 is, in this example, a circular disc consisting of a thin plate or silicone sheet, preferably disposed removably against the face of the bottom 7 of the mold which is turned towards the inside of the mold 1 The diameter of the disk of the interface 3 is therefore preferably slightly smaller than the internal diameter of the bottom 7.

This interface 3 can stick to the bottom 7 of the mold 1 and, preferably, take off from the bottom 7, which can be obtained, for example, by a tacky surface state (permanent or peelable) of the silicone of the 3, or by other means, for example by small flat and thin permanent magnets, embedded in the silicone of the interface 3 and distributed substantially over the entire surface of the disk of this interface 3, each magnet can also be embedded in the molding insert 4 or glued (through the interface 3) in the case where the mold 1 is metal and a metal or diamagnetic alloy. This interface 3, also in a food grade material, is thermally stable from about -40 ° C to about + 300 ° C, to be compatible with the mold 1. Alternatively, other materials can be used to achieve a positioning interface such as 3, for example metal materials, ceramics, composites, in particular of synthetic resin reinforced with inorganic or organic fibers, or of polymer materials resistant to temperatures of the order of + 300 ° C. The molding insert 4 is, in this example, also in the form of a circular flat disc, of a diameter substantially equal to that of the interface 3, and a material also of food grade, which may also be silicone, or a metallic, ceramic, composite or synthetic material, in particular a polymer that is also resistant to temperatures of the order of + 300 ° C. The molding insert 4 is adapted to be fixed, preferably removably, on the positioning interface 3 in the mold 1, as shown in the insert 4 is fixed its two indentations to the outside of the insert 4 and towards the inside of the mold 1, as clearly shown in FIGS. 1 and 3. It is also possible for one of the indentations to protrude outwardly from the insert 4 and the other indent towards the interior of the insert 4, or that the two cavities are recessed towards the inside of the insert 4 10 as already mentioned above in the second and third examples. The mode of removable attachment of the insert 4 on the interface 3 allows, according to the wishes of the user, to replace this insert 4 by another insert, similar in its structure, but having one or more imprints in different relief (s) fingerprints 5 and 6, according to the wishes of the user. Similarly, the interface 3 may be replaced by an interface possibly of different structure but fulfilling the same functions, namely to allow the positioning of at least one insert such as 4 in the mold 1, during a molding operation. In an example of permanent attachment of at least one insert such as 4 in a mold, the interface such as 3 may itself consist of a layer of glue. With the molding assembly in the configuration of FIGS. 1 and 2, the molding is carried out by pouring, for example, a cake or biscuit dough into the mold 1, until completely covering the insert 4 and its components. raised imprints 5 and 6 (projecting), and then performing a baking operation. 5 and 3 so that protrude after baking, the release of the cake or biscuit obtained, shown at 10 in Figure 4, shows on the top of this cake or biscuit 10, two imprints or embossed markings 11 and 12, which are complementary recessed markings respectively of the shapes of the embossed imprints (projecting) 5 and 6 of the molding insert 4. Of course if at least one of the markings 5 and 6 of the insert 4 is recessed in the insert, and not protruding on the insert 4, then at least one of the corresponding markings 11 and 12 of the cake or biscuit is protruding on the cake or biscuit. Thus, a producer of molded food products, for example an artisan baker or pastry chef, can customize his products, thanks to the molding device of the invention, with at least one interface 3 ensuring the maintenance of at least one molding insert such 4, functioning as a stamp in relief, during the introduction of dough or liquid pasta in the mold 1, the shaping of these dough or pasta, and their cooking or freezing. The final result obtained is to mark the food product thus produced with a marking desired by the professional user of this device. It is understood that by changing the molding insert, which is easy to make, it is possible to economically change the marking of the finished food product. Of course, the invention is not limited to the fixing, removable or permanent, of an insert such as 4 on an interface such as 3 applied, removably or permanently, against the bottom 7 of a mold such as than 1, but it is also possible to adapt the shape and size of at least one interface so that it can be applied and maintained, removably or permanently, against, for example, a portion of the side wall 8 of the mold 1, the fixing, removable or permanent, of a molding insert with at least one relief imprint (recessed or projecting) on such an interface reported against the inner face of a portion of the side wall 8 of the mold 1 is also done by gluing, and possibly takeoff, sticky part (s) or with the aid of small permanent magnets embedded in the food grade material in which said molding insert is made, the corresponding interface may also contain one or more small thin plates of a diamagnetic material embedded in a silicone envelope, for example, to ensure the retention of the insert.

For its part, the interface can also be retained against the side wall 8 of a mold such as 1 by gluing, and possibly removed by take-off, or even, especially when the inserts or glues (s) and peels off (nt) of this interface, by small permanent magnets embedded in the interface, if the mold 1 is metal in a metal or diamagnetic alloy. The invention thus offers, in particular to professionals of the food industry, a custom marking technique for the food products they prepare and market, with the possibility of modifying, in a simple and economical manner, this personalized marking.
