The outer skin is sealed at a predetermined position, and the control unit performs supply control such that the layer A material and the layer B are formed before the multilayer body reaches the predetermined position in the outer skin. The supply of materials is over.

According to this configuration, it is possible to reduce the possibility that the multilayered material adheres to the outer layer of the coated multi-layered material and is to be sealed, and it is possible to suppress the occurrence of poor sealing.

In the above-described multi-layer product manufacturing apparatus of the present invention, the discharge mechanism includes an A-layer material supply unit including an A-layer material supply device for supplying the A-layer material, and a B-layer material supply unit including a B-layer material supply device for supplying the B-layer material; and a discharge portion for discharging the A-layer material and the B-layer material supplied from the A-layer material supply portion and the B-layer material supply portion; The layer material supply device and the B-layer material supply device include a uniaxial eccentric screw pump mechanism, and the uniaxial eccentric screw pump mechanism includes a male screw type rotor that is eccentrically rotated by power driving, and an inner circumferential surface is formed into a female screw type. stator.

According to the present invention, it is possible to manufacture a multilayer product which further utilizes the outer skin packaging multilayer. Therefore, according to the present invention, it is possible to manufacture a multilayered product which is high in added value and can be used in various uses.

In the method for producing a multilayer product according to the present invention, the discharge mechanism performs a discharge operation by a step including the following step, that is, a B layer material discharge start step, in which the B layer material is discharged from the discharge nozzle. The A layer material discharge start step, in which the A layer material is discharged from the discharge nozzle after a predetermined time has elapsed after the B layer material discharge start step, and the A layer material discharge stop step is performed in the A After the layer material discharge start step is performed, in which the discharge of the layer A material is stopped; and the layer B material discharge stop step is performed after the step A material discharge stop step, in which step B is The discharge of the layer material stops.

In the method for producing a multilayer product of the present invention, after the B layer material is discharged in the B layer material discharge start step, the A layer material discharge start step is started to eject the A layer material. Thereby, in the stage in which the multi-layered material is started to be discharged, it is possible to suppress the material of the layer A which is to constitute the inner layer from flowing out to the outer side of the material of the layer B which is to constitute the outer layer. In addition, in the multilayer of the present invention In the product manufacturing method, after the layer A material is discharged, the layer A material to be formed into the inner layer is discharged in the step of discharging the layer A material, and then the layer B is formed in the layer B material discharging stop step.

In order to prevent deterioration of the A-layer material and the B-layer material, it is preferable to prevent the A-layer material and the B-layer material from adhering to the vicinity of the end of the discharge nozzle as much as possible while stopping the discharge period for a short period of time. In the case of the outside air, it is particularly necessary to prevent exposure to the outside air when the layer A material and the layer B material are foods and the like. Further, when the A layer material or the B layer material is adhered to the vicinity of the end portion of the discharge nozzle, the subsequent discharge operation of the A layer material or the B layer material is performed, and the discharge amount of the A layer material or the B layer material is correspondingly increased. The amount near the end of the spout nozzle is likely to cause the manufacturing quality of the multilayer product to be uneven.

Further, the discharge nozzle used in the method for producing a multilayer product of the present invention is configured as an A-layer material discharge cylinder and a B-layer material discharge cylinder Since they are arranged in a substantially concentric manner, the A-layer material and the B-layer material adhering to the end portions of the A-layer material discharge cylinder and the B-layer material discharge cylinder may be mixed with each other during the stop of discharge. If the A layer material and the B layer material are mixed, not only the appearance is not good, but also problems such as deterioration of characteristics are likely to occur. Specifically, in the case where the A layer material and the B layer material are foods, in addition to the appearance problems caused by the mixing, there may be problems in food hygiene, or changes in taste or aroma. Problems such as problems, which greatly damage the commodity value of multi-layer products. In order to solve these problems, it is preferable to suck back the A layer material and the B layer material toward the inside when the discharge of the A layer material and the B layer material is stopped.

In the method for manufacturing a multilayer product according to the above problem, the B layer material supply device connected to the B layer material discharge cylinder and the A layer material supply device connected to the A layer material discharge cylinder respectively have uniaxial eccentricity a screw pump mechanism including a male screw type rotor that is eccentrically rotated by power and a stator whose inner peripheral surface is formed into a female screw type; and stops discharging A in the A layer material discharge stop step In the case of the layer material, the rotor of the A-layer material supply device is operated in a direction opposite to the direction in which the A-layer material is discharged, and when the B-layer material is stopped in the B-layer material discharge stop step, the B-layer material is supplied. The rotor of the device operates in a direction opposite to when the material of the B layer is discharged.

According to this configuration, when the supply of the layer A material and the layer B material is stopped, it is possible to suppress the end of the discharge nozzle due to the influence of surface tension or the like. A layer material and B layer material remain in the vicinity. In addition, various problems that may occur due to the A layer material and the B layer material remaining in the vicinity of the discharge nozzle end portion can be prevented.

Further, the multilayer product of the present invention is characterized in that it is produced by the above-described multilayer product producing apparatus of the present invention.

The multilayer product of the present invention is produced by the above-described multilayer product producing apparatus of the present invention, and is further obtained by packaging a multilayered product with a sheath. Therefore, the multi-layer product of the present invention has a higher added value than a product which is only a multilayer, and can be used in various uses.

The control unit 10e is a part that performs the operation control of the discharge mechanism unit 10a, the molding mechanism unit 10b, the film feeding mechanism 10c, and the sealing mechanism unit 10d. In other words, the control unit 10e controls the operation of the inner layer material supply device 22 and the outer layer material supply device 32 constituting the discharge mechanism portion 10a, thereby controlling the supply of the inner layer material and the outer layer material. Further, by controlling the discharge mechanism unit 10a, the operation of the molding mechanism unit 10b, the film feeding mechanism 10c, or the sealing mechanism unit 10d is controlled in accordance with the discharge state of the multilayered material, and the outer skin S is formed by the film F. The multilayer is packaged to form a multilayer product P.

"Manufacturing Method for Multilayer Product P"

Hereinafter, referring to the flowchart shown in FIG. 5 and the time chart shown in FIG. 6, The manufacturing method of the multilayer product P executed under the operation control of the control unit 10e will be described in detail.

(step 1)

In step 1, it is confirmed whether or not the operation signal of the multilayer product manufacturing apparatus 10 is in an ON state. When it is confirmed that the operation signal is turned on, the control flow proceeds to step 2.

(Step 2)

In step 2, the operation of forming the outer skin S by the film F is started under the control of the control unit 10e. Then, the control flow proceeds to step 3.

(Step 3)

In step 3, the outer layer material supply device 32 is used to supply the outer layer material (see Fig. 6). As a result, in the discharge nozzle 42 provided in the discharge unit 40, the outer layer material is discharged downward from the gap formed between the inner layer material discharge cylinder 52 and the outer layer material discharge cylinder 54 (the outer layer material discharge start step).

(Step 4)

In step 4, it is confirmed whether or not a predetermined time t3 has elapsed after the ejection of the outer layer material in step 3 (refer to Fig. 6). Here, the predetermined time t3 is based on various conditions such as the viscosity of the outer layer material and the inner layer material, the discharge speed, the shape of the discharge nozzle 42, and the thickness of the outer layer material constituting the multilayer product. When the setting is made, the outer layer material and the inner layer material may be simultaneously ejected according to the conditions without setting the predetermined time t3 (t3 = 0). When it is confirmed in step 4 that the predetermined time t3 has elapsed, the control flow proceeds to step 5 (the inner layer material discharge start step).

(Step 5)

In the step 5, the discharge of the outer layer material is started in the above step 3, and the operation of discharging the inner layer material downward from the inner layer material discharge cylinder 52 of the discharge nozzle 42 is started. That is, from the time when the outer layer material is ejected in step 3 and the predetermined time t3 elapses, the outer layer material is discharged and the inner layer material is started to be ejected.

(Step 6)

In step 6, it is confirmed whether or not the predetermined time t4 has elapsed after the ejection of the inner layer material in step 5 (see Fig. 6). The predetermined time t4 is appropriately adjusted in accordance with the size (length) of the multilayer produced. When it is confirmed in step 6 that the prescribed time t4 has elapsed, the control flow proceeds to step 7.

(Step 7)

In step 7, the direction of rotation of the rotor 102 of the inner layer material supply device 22 is switched to a direction opposite to that when the inner layer material is discharged within a predetermined time t5. That is, as shown in FIG. 6, the output as the control signal of the rotor 102 is inverted before the predetermined time t4 has been confirmed in step 6. Control signal. Thereby, the inner layer material supply device 22 performs an operation of sucking back the inner layer material supplied to the discharge nozzle 42 in the period up to step 6. When the predetermined time t5 has elapsed after the start of the suckback operation of the inner layer material, the control flow proceeds to step 8.

(Step 8)

In step 8, the rotor 102 that is moving in the suckback direction of the inner layer material is stopped from rotating (steps 7 to 8: inner layer material discharge stop step). Then, the control flow proceeds to step 9.

(Step 9)

In step 9, it is confirmed whether or not a predetermined time t1 has elapsed after the start of ejection of the outer layer material (see Fig. 6). Here, although the discharge of the inner layer material has been completed up to the above step 8, the discharge of the outer layer material is not completed but continues. Then, when it is confirmed that the predetermined time t1 has elapsed after the start of ejection of the outer layer material, the control flow proceeds to step 10.

(Step 10)

In step 10, the direction of rotation of the rotor 202 provided in the outer layer material supply device 32 is switched to a direction opposite to that when the outer layer material is discharged, within a predetermined time t2. In other words, the outer layer material supply device 32 performs an operation of sucking back the outer layer material toward the discharge nozzle 42 in the period up to the previous step. As shown in Fig. 6, the prescribed time t2 required for the suckback of the outer layer material is much less than the prescribed time t1. When the suckback action of the outer layer material begins When the predetermined time t2 has elapsed, the control flow proceeds to step 11.

(Step 11)

In step 11, the supply of the outer layer material is stopped by switching the rotor 202 of the outer layer material supply device 32 to the rotation stop state (steps 10 to 11: outer layer material discharge stop step). Thereby, a series of discharge operation of the multilayered material which is performed from step 3 to step 11 is completed. Then, the control flow proceeds to step 12.

(Step 12)

In step 12, the film feeding mechanism 10c is operated to convey the film F (skin S) of the length required to form the sealing portion 84 toward the downstream side. That is, if a multilayer is present in the formed portion of the sealing portion 84, the sealing portion 84 cannot be formed smoothly, which may result in poor sealing. Therefore, the operation of transporting the film F of the length required to form the sealing portion 84 toward the downstream side is performed while the multi-layered material is stopped. Thus, one of the series of actions shown in the flowchart of FIG. 5 and the time chart of FIG. 6 ends.

As described above, according to the multi-layer product manufacturing apparatus 10, the multi-layered object can be wrapped by the outer skin S, and the film F (the outer skin S) can be sealed by the sealing mechanism portion 10d, and the outer skin S is formed by the formed mechanism portion 10b. A film F formed into a cylindrical shape is formed. Thereby, it is possible to provide the multilayered product P which is easy to use or preserve and which is good in hygienic use. Further, the outer layer S is used to wrap the multi-layer discharged from the discharge mechanism portion 10a as described above. In the case of a material, even if a multilayer material is produced using a soft material, it is easy to carry it without damaging its shape. Further, since it can be provided in a state in which the multilayered body is wrapped by the outer skin S, it is possible to easily perform processing such as heating or cooling. Thus, according to the multilayer product manufacturing apparatus 10 of the present embodiment, it is possible to increase the added value of the multilayer and to diversify its use.

Further, in the present embodiment, as the multilayer product manufacturing apparatus 10, a structure for manufacturing a multilayered structure in which a double-layer structure constituting the outer periphery of the inner layer material of the center is covered with one layer of the outer layer material is exemplified, but the present invention does not As defined herein, the multilayer product manufacturing apparatus 10 can also be formed as a structure for manufacturing a multilayer having a multi-layer structure. For example, in the case of manufacturing a three-layered multilayer product P including a center layer P4, an intermediate layer P5, and an outer layer P6 from the center side toward the outside, the multilayer product manufacturing apparatus 10 is formed into a structure in which, as shown in FIG. The nozzle structure 44 (also referred to as "first nozzle structure 44") which forms the first discharge region 42a and the second discharge region 42b by the inner layer material discharge cylinder 52 and the outer layer material discharge cylinder 54 is used in the same manner as the above-described discharge nozzle 42. In addition, a third discharge area 42c is formed between the outer layer material discharge cylinder 54 and the third discharge cylinder 56 by providing another discharge cylinder (third discharge cylinder 56) that encloses the outer layer discharge cylinder 54. Thus, in addition to the first nozzle structure 44, a second nozzle structure 46 composed of the outer layer material discharge cylinder 54 and the third discharge cylinder 56 is formed. Thereby, by forming the nozzle structure into a multilayer structure, it is possible to further multilayer the discharged material formed in the discharge mechanism portion 10a.

As described above, according to the multilayer product manufacturing apparatus 10, the outer layer material may use a material having the same viscosity as that of the inner layer material or having a viscosity lower than that of the inner layer material. Therefore, according to the multi-layer product manufacturing apparatus 10, it is possible to manufacture a multi-layered product P in which the outer layer material is formed of a material having a lower viscosity than the inner layer material, which cannot be manufactured by a packaging product manufacturing apparatus of the prior art.

As described above, in the multi-layer product manufacturing apparatus 10, in the manufacturing process of the multi-layered product P, the supply control is performed in such a manner that the multilayered material discharged from the discharge mechanism portion 10a reaches the position where the sealing portion 84 should be formed in the tubular film F. The supply of the inner layer material and the outer layer material is stopped at the previous time. By performing such control, it is possible to reduce the possibility that the multilayered material adheres to the position where the sealing portion 84 should be formed on the film F, and it is possible to suppress the occurrence of a problem that the sealing portion 84 cannot be formed smoothly.

Further, in the multilayer product manufacturing apparatus 10, the inner layer material supply device 22 and the outer layer material supply device 32 are devices including the uniaxial eccentric screw pump mechanisms 100 and 200. Therefore, the supply state of the inner layer material and the outer layer material can be controlled with high precision, so that an appropriate amount of the inner layer material and the outer layer material can be discharged at an appropriate timing in the manufacturing process of the multilayer product. Therefore, according to the multilayer product manufacturing apparatus 10, the manufacturing quality of the multilayer product can be further improved.

Further, the uniaxial eccentric screw pump mechanisms 100 and 200 constituting the inner layer material supply device 22 and the outer layer material supply device 32 can appropriately switch the flow directions of the inner layer material and the outer layer material by adjusting the rotation directions of the rotors 102 and 202. . Therefore, even the inner and outer materials It is also possible to prevent the occurrence of unexpected dripping and the deterioration of the quality of the multilayer product due to dripping by using a material having a low viscosity and by rotating the rotors 102 and 202 in the reverse direction when the supply of each material is stopped.

Further, the configuration of the uniaxial eccentric screw pump mechanisms 100 and 200 constituting the inner layer material supply device 22 and the outer layer material supply device 32 is extremely simple. Thereby, the manufacturing cost of the multilayer product manufacturing apparatus 10 and the maintenance characteristics can be suppressed.

In the multilayer product manufacturing apparatus 10, since the inner layer material supply device 22 and the outer layer material supply device 32 are provided with the uniaxial eccentric screw pump mechanisms 100 and 200, it is possible to accurately control the start and end of discharge of the inner layer material and the outer layer material. Therefore, when the predetermined time t3 elapses after the supply of the outer layer material is started by the outer layer material supply device 32 as described above, the inner layer material supply device 22 starts to supply the inner layer material, and the outer layer material supply device is used. When the predetermined time t1 before the supply of the outer layer material is stopped until the supply of the outer layer material is stopped for a predetermined period of time, the inner layer material supply device 22 is stopped from supplying the inner layer material. In this case, the high-quality multilayer product can be stably produced.

In addition, as a method of manufacturing the multilayer product P of the above-described embodiment, the outer layer material discharge start step (step 3) and the inner layer material discharge start step (step 5) are sequentially performed as shown in the control flow in FIG. 5 . An example of each step of the layer material discharge stopping step (steps 7 to 8) and the outer layer material discharge stopping step (steps 10 to 11) may be further added in addition to these steps. Specifically, after the outer layer material is discharged from the start step and the inner layer Before the material discharge start step, the rotor 102 of the inner layer material supply device 22 is rotated in a direction opposite to that when the inner layer material is discharged, by a predetermined amount of the outer layer material suction step.

By providing the above-described outer layer material suction step, after the outer layer material discharge start step, the outer layer material discharged from the outer layer material discharge cylinder 54 of the discharge nozzle 42 and adhering to the front end portion thereof is sucked to the inner side of the inner layer material discharge cylinder 52. Therefore, before the inner layer material discharge start step, a small amount of the outer layer material is filled in the front end portion of the inner layer material discharge cylinder 52. In this state, when the manufacturing step is shifted from the outer layer material suction step to the inner layer material discharge start step, the inner layer material is discharged after the outer layer material filled in the front end portion of the inner layer material discharge cylinder 52 is discharged. Therefore, the multilayer product P thus produced has a structure in which the outer layer material is reinforced from the inner layer material discharge cylinder 52 and the lower portion of the inner layer material is reinforced by the inner layer material discharge start step. Thereby, it is possible to suppress manufacturing defects such as leakage of the inner layer material from the bottom side of the multilayer product P due to the influence of the weight of the inner layer material, etc., thereby contributing to improvement in productivity.

The multilayer product manufacturing apparatus 10 can manufacture a multilayered product P in which a plurality of layers are covered by a film F, but the multilayer product manufacturing apparatus 10 can also be configured to perform heat treatment or sterilization treatment on the multilayer product P. . Specifically, as shown by the two-dot chain line in FIG. 1, the multi-layer product manufacturing apparatus 10 is provided with a heat treatment apparatus 90 capable of further encapsulating the multilayer product P of the multilayer using the outer skin S. Either or both of the heat treatment and the cooling treatment are performed. In the case of such a configuration, it is possible to The post-treatment such as heat treatment such as heat treatment or cooling treatment is performed on the multilayer material surrounded by the outer skin S, whereby the added value of the multilayer product P can be further improved.

Specifically, by performing heat treatment, it is possible to obtain a product obtained by heating the multilayered article surrounded by the sheath S, and an effect such as a sterilization effect can be expected. Further, by performing the cooling treatment, it is possible to obtain an effect of forming a product which is completed after cooling the multilayered body surrounded by the outer skin S, or forming the multilayered product P to be suitable for storage in a refrigerated state or a frozen state. The state and other effects.

In the above, the discharge mechanism portion 10a of the multi-layer product manufacturing apparatus 10 is provided with one discharge nozzle 42. However, the present invention is not limited thereto, and the multi-layer product manufacturing apparatus 10 may be configured to include a plurality of discharge nozzles 42. . In this case, the inner layer material and the outer layer material are supplied to the discharge nozzle 42 after the inner layer material and the outer layer material supplied from the inner layer material supply device 22 and the outer layer material supply device 32 are distributed, and the like, and the plural layer can be discharged at a time. A multilayer. In addition, by providing the molding mechanism portion 10b, the film feeding mechanism 10b, the sealing mechanism portion 10d, and the like for each of the plurality of discharge nozzles 42, it is possible to simultaneously form a plurality of layers of the multi-layered product by the outer skin S. operation. With this configuration, it is possible to mass-produce a multilayer product of the same quality.

In the above embodiment, an example in which the multilayered product can be produced in the following manner is exemplified, which means that the discharge nozzle 42 is in a fixed state, and the outer skin S is conveyed by the film feeding mechanism 10c while discharging more. In the form of the layer, the outer skin S is formed of the film F formed by the molding mechanism portion 10b. However, the present invention is not limited thereto, and the discharge nozzle 42 may be relatively moved with respect to the outer skin S. In other words, in the example described in the present embodiment, the discharge nozzle 42 can be moved up and down, and the multilayered object can be discharged into the outer skin S while the discharge nozzle 42 is moved upward.

In the above-described embodiment, the multilayer structure product is formed by the film F by the molding mechanism portion 10b, and the multilayer body is discharged from the discharge mechanism portion 10a while forming the outer skin by the film F. However, the present invention is not limited thereto. . In other words, the multilayer structure may be discharged from the discharge mechanism portion 10a into the separately prepared outer skin without providing the molding mechanism portion 10b.

Specifically, for example, as shown in FIG. 8 or FIG. 9, a material made of rubber, a film, a resin, or the like may be prepared as a sheath, and a multi-layered material may be discharged from the discharge nozzle 42 of the discharge mechanism portion 10a to the outer skin. The package is completed after the discharge is completed. In the case where the outer skin utilizes a substance having elasticity, as shown in Fig. 8, the multilayer is spit out through the outer skin, and the outer skin is deformed like a balloon. Thereby, it is possible to manufacture a multilayer product having a shape conforming to the deformation of the material constituting the outer skin (spherical in the illustrated example). More specifically, in the example shown in FIG. 8, first, as shown in FIG. 8(a), the outer layer material is discharged in a state in which the discharge nozzle 42 is inserted into the outer skin S. Thereby, the outer layer material as shown in (b) of FIG. 8 is discharged into the outer skin S. Then, the inner layer material is discharged from the discharge nozzle 42 within a predetermined time from a predetermined time (see (c) of FIG. 8). Then, the discharge nozzle 42 is taken out from the outer skin S and sealed to the outer skin S. The spherical multilayer product was formed as shown in (d) of Fig. 8 .

Further, in the case where the outer skin is a material which does not deform even if a multilayer is placed inside, as shown in Fig. 9, it is possible to manufacture a multilayer product which conforms to the shape of the outer skin formed in advance. More specifically, in the example shown in FIG. 9, first, a state in which the discharge nozzle 42 is inserted into the outer skin S as indicated by an arrow in (a) of FIG. 9 is formed. In this state, as shown in FIG. 9(b), the discharge nozzle 42 is moved in a direction away from the bottom side of the outer skin S while the outer layer material is discharged. Thereby, the state in which the outer layer material is first ejected into the outer skin S as shown in (b) of FIG. 9 is obtained. Then, the inner layer material is discharged while discharging the outer layer material from the discharge nozzle 42 within a predetermined time from the time when a predetermined amount of the outer layer material is discharged into the outer skin S (see (c) of FIG. 9). Then, when the discharge nozzle 42 is moved to the outside of the outer skin S, the multilayered body is accommodated in the outer skin S as shown in (d) of FIG. In this state, the outer skin S is encapsulated to form a multilayer product as shown in (e) of FIG.

More specifically, when a fish cake or a sausage containing a filling is produced, a meat meal which is a raw material for feeding fish cake or sausage as an outer layer material is supplied as a material for the filling as an inner layer material. In addition, making bread or taro In the case of the outer layer material, the raw material of the bread or the steamed bread is supplied, and the filling material is supplied as the inner layer material. By doing so, it is possible to manufacture a multi-layered food containing a filling. In addition, when the heat treatment apparatus 90 is provided as described above, the multilayered material in a state in which the filling material is wrapped in the meat emulsion or the raw material can be wrapped by the film F and directly heated in this state to prepare a food. In addition, it is possible to form a state suitable for storage by refrigerating or freezing the state in which the multilayer containing the filling material is wrapped by the film F. Further, the food made by the multi-layer product manufacturing apparatus 10 can be cooked in a state in which the film F is wrapped or the film F is removed before being eaten, which is convenient.

Alternatively, the film F may be formed using an edible material such as rice paper. According to this configuration, it is possible to provide a multi-layered food which can be directly consumed without peeling off the film F.

[Embodiment 2] <<Example of Manufacturing Apparatus and Manufacturing Method of Industrial Product>>

The above multilayer product manufacturing apparatus 10 can also be used to manufacture industrial products other than food. Specifically, by utilizing the outer layer material effectively, a material having a viscosity equal to or lower than that of the inner layer material can be used to form the multi-layer product P, and the following deodorant product or fragrance is used. The product, or a bathing product, etc., is enclosed in a tubular film F, and can be provided in the form of a multi-layered product P, which is a liquid or gel-like deodorant or a fragrance. Layer material The product is wrapped in a material constituting the outer layer of the outer skin and formed into a spherical or beaded product, and the bathing product is a product formed by encapsulating an inner layer material such as soap or a bathing agent with a gel-like outer layer material or a water-soluble outer layer material. The multilayer product P thus produced may be used by the user after peeling off the film F, or may be directly applied to the user in a state in which the film F is wrapped.

[Example 3] <<Example of Manufacturing Apparatus and Manufacturing Method of Artificial Egg>>

In the multilayer product manufacturing apparatus 10 described above, an artificial egg can be produced by using an artificially prepared egg white component and an egg yolk component as an outer layer material and an inner layer material, respectively. The egg thus formed has a cross-sectional shape in which the egg yolk is located at a substantially central portion of the egg white. Further, when the heat treatment apparatus 90 is provided as described above, it is possible to form a boiled egg by directly heating in a state in which the film F is wrapped.

The outer layer of the egg produced as described above is formed of the film F, so that the problem that the egg is broken by a slight impact like an egg in a natural state does not occur. Therefore, the eggs artificially manufactured by the multi-layer product manufacturing apparatus 10 are suitable for handling, storage, and the like. Further, since the egg white component and the egg yolk component can be prepared in an arbitrary ratio, not only eggs in a natural state can be reproduced in the same ratio, but also an egg having a high proportion of egg yolk components can be produced. In addition, by artificially manufacturing the eggs in this way, the quality can be made uniform.
