Decorative sheet food and its manufacturing method

Abstract

Conventional sheet foods are often manufactured in flat sheets, such as nori seaweed. For decoration, some are printed or cut with a laser, or branded. These are two-dimensional elements produced in flat sheets and do not include three-dimensional elements that take into account the thickness of the sheet food. In addition, the number of processes increases, reducing efficiency and affecting the sheet food ingredients. [Solution] The present invention is not carried out after processing into a flat sheet, but is carried out simultaneously when forming into a sheet. A dot- or embossed mold is used, a mixture of at least water or a binder solution is poured into the chopped food, and the mixture is controlled to produce a thick, thin, and plain part of the sheet food material, thereby providing a decorative sheet food with added value.

Description

[Technical field]

[0001] The present invention relates to a decorated sheet food and to a method for producing the same. [Background technology]

[0002] Conventional sheet foods are created as a flat, single plane, and to add value, designs are printed on the surface of the finished sheet food or burned or cut out with a laser. [Prior art documents] [Patent documents]

[0005] Patent Document 1 describes a basic method for producing sheet type food, and merely produces a single-plane sheet type food.

[0006] Patent Document 2 is a paper processing of basic shapes invented by the present inventor, and is not related to food. (This patent is also an application patent of our company.)

[0007] Patent Documents 3, 4, and 5 disclose a type of printing method, which involves decoration of two-dimensional elements.

[0008] Patent Document 6 is similar to Patent Document 2 but is two-dimensional due to die cutting.

[0009] Patent Document 7 describes a method for applying marks such as letters and figures to the surface of food. This method is applicable to all types of food, and is a two-dimensional element that decorates only the surface by irradiating with a laser.

[0010] Non-Patent Document 1 uses laser processing, while Patent Document 6 uses die cutting and baking, but since the processing is done with a laser beam rather than a watermark, it takes time.

[0011] The conventional sheet foods mentioned above are not efficient because of the additional post-processing required, such as single flat sheets without decoration, two-dimensional printing on the surface for decoration, and laser irradiation processing that can only be done by line drawing, and the food materials are affected by laser burns. Also, these are two-dimensional elements and do not take into account the thickness of the sheet. [Means for solving the problem]

[0012] The present invention provides a decorative sheet-like food that has never been seen before, by forming a pattern with openwork elements consisting of a combination of two or more of thick, thin, and plain parts of chopped food material. The openwork can be black, which shows the shape with the material, or white, which fills the surrounding area with material and leaves the shape blank.

[0013] The present invention can manufacture decorated sheet-type foods by using a mold material that has been subjected to halftone dot processing or embossing. The decorated sheet-type foods manufactured by the above-mentioned method can be transferred (transferred) onto a sheet of food material or non-food material, thereby expanding the range of decoration. Effect of the Invention

[0014] The present invention is capable of producing three-dimensional decorated sheet foods, characterized in that in the sheet forming step of the manufacturing method for sheet foods, a mold material using a halftone dot technique or an embossed mold material is provided, and a mixture of at least water or a binding solution is poured into the desired shredded basic food, thereby forming a watermark pattern with thin and thick shading in the layers of the food material.

[0015] The decorative sheet food of the present invention also expands the range of decoration. It is possible to combine sheet food with a decorative sheet food composed of a watermark pattern. In particular, a sheet food made with a black watermark is effective, and it is also possible to use a sheet food of the same or different quality as the basic food material.

[0016] The present invention uses an edible film or a film that is safe from the standpoint of food hygiene, and can be transferred (transferred) to other foods.

[0017] In practicing the present invention, by varying the quality, quantity and density of the dots, and also by using high and low embossing and dot techniques, thick and thin areas of the base food material can be created to show the effect of watermarks.

[0018] In the manufacturing method of the present invention, in order to maintain the shading of the thick and thin parts by using mold materials with various patterns, if a water-permeable support is used, the basic food material will remain and be shaped. [Brief description of the drawings]

[0020] The following will be described with reference to FIGS. 1 to 33. EXAMPLES

[0021] The method for producing sheet foods is based on that shown in Patent Document 1, JP Patent Publication No. 2002-016961. However, this only applies to single-planar sheet foods, and Patent Documents 2 to 7 and Non-Patent Document 1 involve decorating the sheet foods to add value. This decorating process involves printing or other decoration on the surface of a single-planar sheet food or cutting it out after the food has been completed, and is two-dimensional, not a three-dimensional technical method that takes into account the thickness of the layers of the sheet food.

[0022] This invention is a three-dimensional watermark technique that takes into account the thickness of sheet-type food, and allows for gradation. It is possible to manufacture decorated sheet-type food with a blurring effect.

[0023] Fig. 1 is a flow chart showing the basic manufacturing process of sheet food, which adds the decoration process of the present invention to the sheeting process. After creating a mold using an image processed by a computer and placing it in a molding machine, the basic food ingredients are pre-processed by washing and shredding, and then mixed with at least water and a binding solution, which is poured into the molding machine. After sheeting, post-processing such as drying and transfer (transfer) is performed to produce a decorated sheet food.

[0024] Figure 2 is a schematic diagram showing a simple flow of the sheeting process. The mixture is poured into a laminate of mold materials and supports installed in a molding machine, and the basic food material remains on the support. It is then dried with infrared rays or the like, and then transferred (moved) from the support to another sheet material to complete the process.

[0025] Figure 3 is a schematic diagram of a mold material 3a for making sheet-type food by the black watermark method. It uses a water-resistant material such as film, and the black part is fully open in the shape of a basic figure, with some parts being halftone-processed. If the black part is made high density by halftone-processing, the same effect as a fully open part can be obtained.

[0026] Figure 4 shows the process of forming sheet food by the black watermark method. In a forming machine 1 equipped with a blind 2, a mold material 3a made of a waterproof material and a support 4 that is safe from the viewpoint of food hygiene but allows water to pass through are placed on the blind 2, and a mixture 5 of at least water and a binding solution is poured into the chopped basic food, and air and water are sucked in from below.

[0027] Figure 5 is a cross-sectional view of the state after the mixture is poured in and dried in the molding process using the mold material 3a in Figure 3. The mixture 5 is sucked in in large amounts at all the openings of the mold material 3a and in small amounts at the dotted areas, and basic food ingredients 5' and 6' from which water and other substances have been removed remain on the support 4 and are in a dried state.

[0028] FIG. 6 is a schematic diagram showing a sheet-like food product of a basic food material 6' formed on a support 4 in the form of a basic figure, the basic food material 5' being thick-walled and the dotted areas being thin-walled.

[0029] Figure 7 is a schematic diagram of mold material 3b for making sheet food by overlapping a thick sheet of a basic shape on a thin full-surface sheet, and uses the waterproof material mentioned above. The full surface is perforated with halftone dot processing, and the black part is fully open in the shape of the basic shape. Also, by controlling the size and density of the holes with halftone dot processing, it is possible to control the thickness of the sheet.

[0030] Figure 8 shows the process of forming sheet food by the black watermark method. In a forming machine 1 equipped with a blind 2, a mold material 3b made of a waterproof material and a support 4 that is safe from the viewpoint of food hygiene but allows water to pass through are placed on the blind 2, and a mixture 5 of at least water and a binder solution is poured into the chopped basic food, and air and water are sucked in from below.

[0031] Fig. 9 is a cross-sectional view of the state after the mixture is poured into the molding process using the mold material 3b and then dried. The mixture 5 is sucked out, and most of the basic food ingredients 5' from which the water and other substances have been removed remain in the areas of the support 4 that correspond to all the openings of the mold material 3b, while the rest of the areas are perforated by halftone dot processing, leaving only a small amount of basic food ingredients 6', which are in a dried state.

[0032] Fig. 10 is a schematic diagram of a sheet-like food in which a thick basic food material 5' of a basic shape is overlaid on a thin, full-sheet basic food material 6' to form an integrated sheet food. In the halftone-processed area inside the basic shape, part of the basic food material 5' is thin and transparent.

[0033] Fig. 11 is a schematic diagram of a mold 3c for making a sheet food product in which a thick full-surface sheet is overlaid with a thin basic-shape sheet. The above-mentioned waterproof material is used, and the black part is a full-opening in a shape other than the basic shape. The grey areas are processed using halftone dots to control the size and density of the holes.

[0034] Figure 12 shows the process of forming sheet food by the white watermark method. In a forming machine 1 equipped with a blind 2, a mold material 3c made of a waterproof material and a support 4 that is safe from the viewpoint of food hygiene and that allows water to pass through are placed on the blind 2, and a mixture of at least water and a binding solution is poured into the chopped basic food, and air and water are sucked in from below.

[0035] Figure 13 is a cross-sectional view of the state after the mixture is poured in and dried in the molding process using the mold material 3c in Figure 11. The mixture 5 is sucked out, and most of the basic food ingredients 5' from which water and other substances have been removed remain on the support 4 in the areas that correspond to all the openings of the mold material 3c, while the rest of the area is perforated by halftone dot processing, leaving only a small amount of basic food ingredients 6' remaining in the dried state.

[0036] Figure 14 is a schematic diagram of a thick, full-sheet basic food material 5' overlaid with a thin, basic-shape basic food material 6' sheet. The grey parts of the mold 3c in Figure 11 are processed with halftone dots to control the size and density of the holes, which creates a thick and thin shading in the food sheet.

[0037] Up until now, the molding process has been carried out by placing the support 4 on top of the mold members 3a, 3b, and 3c, but it is now possible to switch between the two and place the mold members 3a, 3b, and 3c on top of the support 4, thereby forming a thicker food material 5'. The most important prerequisite is that both materials are safe from the standpoint of food hygiene, and this is explained in the next section.

[0038] Figure 15 is a schematic diagram of a mold 3a for making sheet food in the shape of a basic figure only. It uses a waterproof material such as a film, and the black part is fully open in the shape of the basic figure, and some parts are halftone dot holes. The black part also has a high density halftone dot, which can produce the same effect.

[0039] Figure 16 is a diagram of the state when a mold material 3a is placed on a support 4 and a mixture is poured in, which is a black openwork technique in which the basic food material thickens into the shape of a basic figure. In a molding machine 1 equipped with a blind 2, a support material 4 that is safe from the viewpoint of food hygiene and allows water to pass through, and a mold material 3a made of a material that does not allow water to pass through are placed on top of the blind 2, and a mixture of chopped basic food mixed with at least water and a binding solution is poured in, and air and water are sucked in from below.

[0040] Figure 17 is a cross-sectional view of the state after the mixture is poured in and dried in the molding process using the mold material 3a in Figure 15. The mixture 5 is sucked in and passes through all the openings and dotted parts of the mold material 3a, and basic food ingredients 5', 6' from which water and other substances have been removed remain on the support 4 and are in a dried state.

[0041] FIG. 18 is a schematic diagram of the support after the mixture is poured in during the molding process using the mold material 3a of FIG. The mixture 5 is sucked and passes through all the openings of the mold 3a to produce the basic food material 5' from which water and other substances have been removed. becomes thick on the support 4. Since a part of the basic shape is perforated by halftone dot processing, only a small amount of the basic food material passes through, and the basic food material 6' remains thin on the support 4 and is in a dried state.

[0042] Figure 16 illustrates the state in which the mold 3a and the support 4 in Figure 4 are interchanged, but it is also possible to produce the decorated sheet-type food as described above by going through the process of interchangeably replacing the molds 3b, 3c and the support 4 in Figures 8 and 12.

[0043] Figure 19 is a schematic diagram of the black watermark method for making sheet food of a basic shape, in which an embossed portion 23a is formed on the white part of the support 4 other than the basic shape using a water-impermeable material, and the basic shape is fully open in the black part.

[0044] Figure 20 shows the state of the mixture flowing into a waterproof embossed section 23a provided on a water-permeable support 4, and is a black openwork technique in which the basic food material becomes thick in the shape of a basic figure. In a molding machine 1 provided with a blind 2, a hygienically safe support 4 that allows water to pass through is provided with an embossed section 23a made of a water-impermeable material on top of the blind 2, and a mixture of chopped basic food mixed with at least water and a binder solution is poured into the embossed section, and air and water are sucked in from below.

[0045] FIG. 21 is a cross-sectional view showing a state in which a support 4 having a waterproof embossed portion 23a in the white area other than the basic shape in FIG. 19 is used, and after the mixture is poured in during the molding process, it dries and the basic food material 5' remains other than the embossed portion 23a.

[0046] FIG. 22 is a schematic diagram showing a sheet-like food product in which the basic food ingredient 5' remains only in the area of ​​the basic figure due to the waterproof embossed portion 23a provided outside the basic figure, resulting in a black outline of the sheet-like food product.

[0047] Figure 23 shows a sheet food with openwork, in which a thick sheet of a basic shape is overlapped on a thin full-surface sheet, and an embossed section 23b is provided on a support 4 using a waterproof material. The black section is fully open in the shape of the basic shape, and the grey section is a schematic diagram of embossing with halftone dot processing that controls the size and density of the holes. If the black section is also processed with high-density halftone dot processing, the same effect as a full open section can be obtained.

[0048] Figure 24 shows the state of the mixture poured into a waterproof embossed section 23b on a water-permeable support 4, and is a black openwork technique in which the basic food material becomes thick in the shape of a basic figure. In a molding machine 1 equipped with a blind 2, a water-permeable support 4 that is safe from the viewpoint of food hygiene and that is water-permeable is provided above the blind 2, and an embossed section 23b made of a material that does not pass water is provided, and a mixture of chopped basic food mixed with at least water and a binding solution is poured into the area, and air and water are sucked in from below.

[0049] FIG. 25 shows a cross-sectional view of a thick basic food material 5' because the basic shape is fully open and not embossed, while the entire sheet portion and the inside of the basic shape are embossed with a halftone dot process, resulting in a low flow rate of the mixture 5 and a thin basic food material 6'.

[0050] FIG. 26 is a schematic diagram showing a thick basic food material 5' integrated onto a shaded basic food material 6' due to halftone embossing.

[0051] Figure 27 shows a sheet food product with openwork, in which a thick full-surface sheet is overlaid with a thin basic-figure sheet, and an embossed section 23c is formed on a support 4 using a waterproof material. The black section is fully open in a shape other than the basic figure, and the grey section is a schematic diagram of a halftone embossed process that controls the size and density of the holes. If the black section is also subjected to a high-density halftone process, an effect close to a full open shape can be obtained.

[0052] Figure 28 shows the state of the mixture poured into a waterproof embossed section 23c on a water-permeable support 4, and is a white openwork technique in which the basic food material becomes thin-walled in the shape of a basic figure. In a molding machine 1 equipped with a blind 2, a hygienically safe support 4 that allows water to pass through and an embossed section 23c made of a waterproof material are provided above the blind 2, and a mixture of chopped basic food mixed with at least water and a binder solution is poured into the area, and air and water are sucked in from below.

[0053] FIG. 29 is a cross-sectional view of a basic food material 6' in a thin state due to a small flow rate caused by dots and embossing being applied to a part of the basic shape.

[0054] FIG. 30 is a schematic diagram showing a thick basic food material 5' and a shaded basic food material 6' integrated together.

[0055] Figure 31 shows an image of a sheet food made by shredding carrots and transferring (transferring) the decorative sheet food of the present invention, nori seaweed, as shown in Figure 2. As can be seen in the image, the degree of shrinkage of each food material must be taken into consideration.

[0056] FIG. 32 is a schematic diagram showing the transfer of the present invention to a rice ball made from white rice.

[0057] FIG. 33 is an image showing an embodiment of the present invention, in which a decorated sheet food product is made from seaweed and transferred onto a rice ball.

[0058] 6, 18 and 22 show the process of constructing a sheet-type food product on a support 4. Thus, Once this forming is complete, there is a possibility that the connections between the sheet-like foods of each basic figure may be lost. Therefore, it is possible to transfer (transfer) them onto a sheet of food material or non-food material as described in claim 5. Figure 31 shows what has been transferred (transferred) onto a food material, and Figure 33 shows what has been transferred (transferred) onto a rice ball after being transferred (transferred) onto a non-food material.
