[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mold for molding a semi-solid food such as a kneaded product using a mold, and has a good releasability from the mold and can provide an extremely smooth release surface. It is related to a molding device of.

[0002]

2. Description of the Related Art Heretofore, a molding method using a mold has been generally employed for molding kneaded foods such as croquettes, ganmodoki, and hangers. In this method, a fixed shape is obtained by filling and releasing a raw material into molds of various shapes. As a typical example, a method as shown in FIG. 4 is used. In the example shown in the figure, a molding drum 41 obtained by hollowing out a mold part 40 is used as a mold frame. First, as shown in (a), the mold part 40 is filled with a raw material at a predetermined pressure, and then the molding drum is moved to a position (b). The extruded piece 42 positioned so as to be able to protrude and retract from the molding drum 41 rotates the molded material 4 of the filling material 4 from the mold portion 40.
3 is extruded and the release from the extruded piece 42 is reliably performed using the wire cutter 44.

[0003]

However, in the conventional molding method as described above, when the molded body 43 is rubbed against the inner wall surface of the mold when releasing from the mold, the molded body 43 is removed.
This causes a problem that the surface of the material is roughened, and also causes a problem that a part of the raw material adheres to the forming drum 41 and the wire cutter 44 due to the rubbing. If the surface becomes rough like this, there is no problem when coating the garment like a croquette, but in the case of steamed foods such as hampen, the rough surface form is reflected as it is, It is not preferred and poses a problem in terms of food value. In addition, since a part of the raw material adheres to the molding drum 41 and the wire cutter 44 at the time of release, it is not preferable from the viewpoint of hygiene. Thus, the conventional molding method has a problem in appearance and a problem in hygiene.

Next, the molding method of the present invention will be described in detail with reference to the drawings. FIG. 1 shows an embodiment of a mold capable of realizing the molding method of the present invention. In the figure, reference numeral 1 denotes a mold, a raw material filling portion 2 from which a fluid can be discharged from an inner wall surface, and an outer frame 3.
Consisting of A fluid supply port 4 and a fluid supply joint 5 are connected to the bottom rear surface at the center of the bottom of the outer frame 3, while a recess 6 for fluid introduction is provided on the bottom surface of the raw material filling unit 2. The shape of the concave portion 6 is appropriately set according to the type and flow rate of the fluid to be introduced, and may be provided on the entire bottom surface or in an appropriate pattern such as a cross shape.

In the present method, it is effective to mainly use a porous material for the raw material filling portion 2 so that a fluid can be jetted from the inner wall surface 7. Various materials can be used as the porous material, and details thereof will be described later. First, the details of the molding method of the present invention will be described based on specific examples.

FIG. 2 shows schematically the molding method of the present invention. First, as shown in FIG.
The raw material filling section 2 composed of hemispheres is filled with the raw material 8 made by kneading walleye pollack, salt, starch powder and water at a weight ratio of 40: 1: 2: 3, and then as shown in (b), A small amount of water was mixed with air through the fluid supply pipe 9 and supplied to the raw material filling section 2. By this supply of air, a thin layer 11 of air was formed between the raw material filling section 2 and the molded body 10 of the kamaboko raw material, and extremely good releasability was confirmed. Further, the surface of the molded body 10 after the release was extremely smooth, and no roughening of the surface of the molded body caused by the conventional release method was observed.

In the same manner as in the present embodiment, the hamburger material is filled and air mixed with a small amount of oil is supplied at the time of release, or ice cream is filled and dry ice, ie, cooled, is used instead of air at the time of release. Even when carbon dioxide was supplied, very good releasability was obtained, as in the above-described example.

Further, using the Kamaboko raw material, water was applied to the entire inner wall surface of the raw material filling section 2 before filling, and the releasability and the smoothness of the molded product surface were evaluated in the same manner as described above. With respect to those having high properties, more excellent releasability and surface smoothness were obtained. Further, even when oil was applied instead of water using a hamburger material, more excellent releasability was confirmed.

On the other hand, in such a molding method, particularly in the case of ice cream or the like, the raw material may soak into the discharge holes due to the pressure at the time of filling the raw material filling section 2. However, this problem can be solved by applying a fluid pressure equal to the filling pressure of the raw material in advance and maintaining the pressure until the mold release.

Next, an example of a molding machine using such a molding method is shown as a sectional structure in FIGS. 3A and 3B. In the example shown in the figure, first, as shown in FIG.
And a hopper 2 for material supply is provided above the rotating body 20.
1, a conveyor 22 for taking out a molded body is provided at a lower portion, and a rotating body 20 is positioned so as to be rotatable about a central axis 23. The fluid supply pipes 9, 9 are taken out of the molds 1, 1, and are taken out of the rotating body 20 through the rotating body back plate 24. As shown in FIG. 2B, a fluid supply cell 27 having a fluid supply port 26 via an O-ring 25 is provided so as to cover the through-hole of the fluid supply pipe 9 at the lower position. The fluid supply cell 27 is fixed to the apparatus main body side, and the O-ring 2
5, the rotating body 20 rotates and slides with respect to the fluid supply cell 27 while maintaining airtightness.

In such a molding machine, first, the raw material 8 is filled into the raw material filling portion 2 of the mold frame 1 located at the upper portion from the hopper 21 by a suitable pressing force such as air pressure. Next, the edge 2 of the hopper 21 is
The raw material 8 is cut by 8, and at the same time the mold 1 reaches the lower position, a fluid of a predetermined pressure is supplied from the fluid supply port 26. Then, the molded body 10 is released by ejecting a fluid from the inner wall surface of the raw material filling unit 2 and is discharged onto the conveyor 22 to complete a series of molding operations.

As described above, in the present invention, in order to release the molded body 10 by injecting the fluid from the raw material filling portion 2 in the mold 1, it is desirable that the fluid is injected from the entire inner wall surface. . The present invention can also be basically achieved by forming the raw material filling section 2 from a general metal and forming a shower structure with a large number of minute holes for discharge, but as described above, it is possible to use a porous material. It is more preferable.

As such a porous material, first, a porous casting is excellent, and an aluminum casting will be described below as an example. Aluminum casting is, of course, not a porous material, but by actively utilizing casting defects that have conventionally occurred as defects during casting, porous aluminum casting is extremely useful for realizing the present invention. You can get the body. The production of such a porous aluminum casting can be realized by intentionally generating voids called casting cavities due to gas generation during casting, that is, casting defects. These cavities can be classified into those caused mainly by the molten metal and those caused by the mold.In order to obtain the cavities caused by the molten metal, the casting temperature must be set outside the normal control limits, especially on the high temperature side. Can be easily obtained by: For example, the melting point of aluminum is 660 ° C
However, by casting this at a temperature of about 860 ° C., a casting cavity is formed uniformly over the entire casting, and a porous casting can be obtained. The formation density of the cavities can be controlled by the casting temperature.

Next, in order to obtain a cavity caused by the mold,
For example, it can be easily obtained by intentionally increasing the moisture content of the foundry sand and casting it in a state where degassing is not sufficiently performed. Also in this case, for example, by controlling the moisture content of the molding sand, the formation density of the casting cavities can be controlled.

Next, as the second porous material, a cast body obtained by casting a porous ceramic is excellent. This is made by casting a porous ceramic known in the art together with a metal material such as aluminum, stainless steel, iron or the like, and the formation density of the discharge ports can be controlled by the porosity of the porous ceramic. That is, the porous ceramics is obtained by impregnating a slurry composed of a ceramic raw material and a binder into a polyurethane foam, which is a combustible material, as an example, pyrolyzing and removing the polyurethane foam by drying and baking. By controlling the foaming ratio of, it is possible to finally control the discharge port density in the casting. In addition to the method using a polyurethane foam, other manufacturing methods including a method in which combustible beads and the slurry are mixed and molded and fired are also possible. Can also be set.

As the third porous material, a porous synthetic resin can be used. This has the advantage that it is simplest to use a foamable synthetic resin, and even a complicated shape can be manufactured as an inexpensive mold. As the foamable synthetic resin, besides the above-mentioned polyurethane, general foamable resins such as polystyrene, vinyl chloride resin, phenol resin, urea resin, epoxy resin, polyethylene, and methacryl resin can be widely used. The discharge port density can be easily controlled by the expansion ratio of these synthetic resins.

[0020]

As described above, in the present invention, a mold is used in which a fluid can be discharged from the inner wall surface of the raw material filling section, and after the raw material is filled, the fluid is injected from the inner wall surface to form a molded body. Since the release is performed, a molded product having a smooth surface and excellent design can be obtained. This is because a thin layer of the fluid is formed between the raw material filling section and the molded body by the fluid supplied to the raw material filling section, and the molded body does not rub against the inner wall surface of the raw material filling section as in the related art. Therefore, even in the case of a raw material having tackiness, a molding process having an extremely smooth surface can be performed. Also, by applying water or oil to the inner wall of the raw material filling section before filling the raw material,
The above effects are further enhanced, and the present invention can be applied to a wider range of raw materials.

When a porous casting, a casting obtained by casting a porous ceramic, or a porous synthetic resin is used in the raw material filling portion, the fluid is jetted uniformly from the entire inner wall surface. The effects of the present invention can be maximized. And according to such a molding method of the present invention, it becomes a food excellent in design, which leads to further increase in appetite.
