Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for mass-producing flat baked confectioneries such as okonomiyaki and its apparatus, and more particularly to a manufacturing method for softly baking the edges of the product and its surroundings. Regarding the device.

[0002]

2. Description of the Related Art Okonomiyaki is a type of food made from teppanyaki. In ordinary stores, it is common practice to put ingredients for one serving on an iron plate and bake both sides. in this case,
A mixture of flour, eggs, milk, etc. is used as a base, and vegetables, meat, and other ingredients are placed on top of it and then baked while turning over on an iron plate.

On the other hand, in order to produce a large amount of okonomiyaki, a mold is generally used because a flat iron plate cannot make the planar shape of the product uniform. FIG. 6 shows a schematic diagram of a cooking example of okonomiyaki with a mold.

As shown in FIG. 1A, a flat mold plate 5 is formed.
0 is provided with a plurality of recesses 51 for material filling. In order to increase production efficiency, brackets 52 provided at both ends of the template 50 are connected to, for example, a chain 53 and the like, and the chain 53 is driven to continuously convey a baking line to burn a product. Generally adopted.

A heating source is provided at the upper and lower sides of the template 50 carrying line to sandwich the line. As this heating source, the template 5
Pipe-shaped burner 54 for directly heating 0 from below
A heating head 55 that is located above the template 50 and heats the upper surface of the product by radiant heat is used.

[0006] With such equipment, the material 56 such as the pasty wheat flour or the filling filled in the recess 51 is heated while being conveyed, and after baking, the product is recovered from the recess 51, and the planar shape of the recess 51 is changed. It becomes possible to supply it to the market as a standard flat baked confectionery.

[0007]

Since the surface of the material 56 injected into the recess 51 faces the heating head 55 above it and is heated by the radiant heat from the heating head 55, a soft finish is obtained even after baking. Become.

However, due to the heat transfer from the template 50, the heating temperature of the portion in direct contact with the bottom wall 51a of the recess 51 and the surrounding peripheral wall 51b and the area in the vicinity thereof becomes higher than that of other portions. Cheap. Therefore, when properly baking the inside of the material in the recess 51, too much heat is applied to the bottom and the periphery of the material 56, and the bottom and the periphery of the finished product become hard. When the obtained product has a soft portion and a hard portion, the feeling when eating becomes poor, and the hardened portion is often left after baking. In particular, this tendency is remarkable because the hard portion becomes harder as the temperature of the product decreases after baking.

As described above, in the conventional manufacturing process, even if the product can be mass-produced, the distribution of the heating for the filled material cannot be set uniformly, so that even if the product is properly baked, its bottom and surroundings can be prevented. There is a problem that parts and parts become too hard. This is occurring not only in the field of okonomiyaki, but also in the production of Imagawa ware and the like.

[0010] The problem to be solved in the present invention is to provide a good quality product by uniformly and softly baking the peripheral surface and the inside of the product in the production of baking a baked confectionery by a mold.

[0011]

A method for manufacturing a flat-baked confectionery according to the present invention comprises a baking plate on which a pasty material of the baked confectionery is placed, and a peripheral shape of the baked confectionery placed on the baking plate. In the method for producing a baked confectionery using a mold, the material is supplied to a filling space formed by the baking plate and the mold, and the peripheral portion of the peripheral portion is supplied to such an extent that the material does not flow out from the peripheral portion. Heat and solidify the material,
After this heating and solidification, the mold is removed from the baking plate,
The heating of the material is continued.

Further, it is suitable for such a method for producing baked confectionery.
For manufacturing equipment that can be used,
The following configuration can be adopted.

That is, the baked confectionery manufacturing apparatus of the present invention
Is a baking plate that receives and conveys a pasty material of baked confectionery, a mold that can be brought into contact with and separated from the upper surface in synchronization with the movement of the baking plate, and a molding space formed by the baking plate and the mold. A primary heating system for heating the material of the part to the extent that the material of the part in contact with the mold solidifies a little more than the core part, and the primary heating system is arranged downstream of the line, and the mold is characterized in that it comprises a secondary heating system to continue heating after releasing from the baked plate.

[0014]

When the paste-like material is poured onto the baking plate, the mold is placed on the baking plate, so that the paste-like material is restrained from flowing out by the mold, like a normal mold. The material is filled. When heat is applied to the material from the outside in this state, heat transfer is also performed through the grill and plate, and the material is in contact with the bottom of the grill and the inner wall of the mold. The peripheral surface portion begins to solidify before the core portion. Therefore, if only this peripheral surface part is solidified to some extent, the paste-like material solidifies like a dam even if the form is removed, and the paste-like material does not flow out from the core side. .

Then, if the mold is removed, only the bottom surface of the material remains on the grill plate, and if the upper surface side is heated using radiant heat or the like, the upper surface and The surroundings can be baked uniformly and softly.

1 is a schematic side view showing an entire apparatus for carrying out the manufacturing method of the present invention, and FIG. 2 is a schematic vertical sectional view taken along the line AA of FIG.

In the figure, two chain conveyors 2 running in the line direction are provided at both ends of the frame 1 in the width direction.
a, 2b are arranged and these chain conveyors 2a, 2b
Both ends of the grilling plate 3 are connected at a constant pitch between b.
The chain conveyors 2a, 2b form a loop by the sprockets 2c, 2d provided at both ends of the line, and are driven at a constant speed in the arrow direction in the figure by the drive motor 2e in the frame 1.

Above the pass line of the grill plate 3 and in a portion occupying almost half of the line of the entire apparatus, the grill plate 3
A circulation line for the formwork 4 to be placed on is provided. In this circulation line, two chain conveyors 5a and 5b provided in the width direction of the line are looped around by four sprockets 5c, and a drive motor 5d passes in the direction of the arrow in synchronization with the traveling speed of the grill plate 3. It was possible. Both ends of the mold 4 are connected to the chain conveyors 5a and 5b so that they can travel while always maintaining a substantially horizontal posture. Then, at a position facing the transportation line of the grilling plate 3, the path lines of the chain conveyors 5a and 5b are set so that the lower surface of the formwork 4 is exactly hit on the grilling plate 3 and placed.

A material injection hopper 6 is provided on the most upstream side in a plane area included in the circulation line of the mold 4, and
A primary heating system 7 is provided on the downstream side. The injection hopper 6 is provided with a fixed-quantity cut-out valve and the like, and by intermittently opening and closing this valve, the paste-like material is discharged onto the grill plate 3 in a state where the mold 4 is already mounted, It is possible to automatically fill the grilling plate 3 and the mold 4 that continuously run. Note that the material may be manually injected instead of the automatic filling by the injection hopper 6.

The primary heating system 7 is provided with a plurality of burner heads 7a located below the pass line and a radiant heating head 7b located above. As shown in FIG. 2, the burner head 7a is a pipe-shaped burner, and ignites the gas supplied from the gas pipe 7c to uniformly heat the grill plate 3 in the width direction thereof. The radiant heating head 7b is also connected to the gas pipe 7d in the same manner, and the lower surface of the radiant heating head 7b is exposed above the grill plate 3 to uniformly heat the material in the mold 4 by radiant heat.

Further, a secondary heating system 8 for heating the material on the grill plate 3 after removing the mold 4 is provided in a region of the mold 4 which is located downstream of the circulation line. This secondary heating system 8 is provided with a plurality of burner heads 8a and a total of 6 units of radiant heating heads 8b, and the ratio with the primary heating system 7 is such that the heat power can be optimally adjusted. The burner head 8a and the radiant heating head 8b are exactly the same as those of the primary heating system 7 shown in FIG.

FIG. 3 shows one mold 4 on one baking plate 3.
FIG. 4 is a plan view when the sheet is placed, FIG. 4 is a schematic vertical sectional view taken along the line BB of FIG. 3, and FIG. 5 is a vertical sectional view taken along the line CC of FIG.

As described above, the grilling plate 3 has its both ends connected to the chain conveyors 2a and 2b, and can pass with its upper surface in a horizontal posture at least in the line flowing from the left end to the right end in FIG. And

The formwork 4 has brackets 4a, 4 on both ends thereof.
b is raised, and pins 5e and 5f protruding from the chain conveyors 5a and 5b are inserted into the brackets 4a and 4b to be connected. By making the brackets 4a and 4b rotatable around the pins 5e and 5f, the circulation line can be moved while always maintaining the posture horizontal as shown in FIG. Further, in the illustrated example, a total of four partition walls 4c, which are circular in the illustrated example, are provided (the number of partitions and the shape thereof may be changed as appropriate), and the mold frame 4 is placed on the grill plate 3. When placed, the grill 3 serves as the bottom of the material filling space, and the partition wall 4c forms the peripheral surface of the paste material filling space.

In the above structure, the drive motor 2e on the side of the frame 1 and the drive motor 5d on the side of the circulation line of the form 4 are used.
1 is operated, the chain conveyors 2a, 2b, 5a, 5b run, respectively, as shown by the arrows in FIG. Then, with respect to the grilling plate 3 passing by, the formwork 4 fed from above is synchronized so as to be placed exactly on the grilling plate 3, and the traveling speeds are also made to coincide with each other, so that from the front side of the injection hopper 6. Formwork 4 until it passes through the primary heating system 7.
Is kept on the grill plate 3.

For the integrated baking plate 3 and the mold 4, the material is filled into each partition wall 4c from the pouring hopper 6, and the filling is performed by running the chain conveyors 2a, 2b, 5a, 5b. Will be performed intermittently for subsequent ones. The material in which the partition wall 4c is filled with the material is first heated by the first heating system 7.

In the first heating system 7, the burner head 7a below the grill plate 3 directly heats it, and the radiant heating head 7b above it radiantly heats the material. And
The amount of heat in the first heating system 7 is such that the core of the material in the partition wall 4c is not solidified by firing and the shape of the material does not collapse even if the partition wall 4c is extracted. That is, the peripheral surface of the material in the partition wall 4c contacts the partition wall 4c,
The entire bottom surface is in contact with the grill plate 3 which is directly heated by the burner head 7a. Therefore, the filled material gradually solidifies from the bottom surface and the peripheral surface, so if the peripheral surface is heated and the surrounding area of the material is slightly solidified, the material itself creates a weir. The material does not flow out or lose its shape even without the partition wall 4c.

As described above, by setting the heating amount in the first heating system 7, the mold 4 is removed from the upper surface of the baking plate 3 at a stage where the shape of the material is not lost and the core is not baked and solidified. This is a chain conveyor 5 in the circulation line of the formwork 4.
Since a and 5b have an upward path immediately downstream of the primary heating system 7, the formwork 4 is carried out by a movement that is automatically pulled up from the grill plate 3.

After that, the unsintered material placed on the upper surface of the grill plate 3 is heated again by the secondary heating system 8 as the grill plate 3 moves to the downstream side. Also in this secondary heating system 8, as in the case of the primary heating system 7, both the burner head 8a for directly heating the grill 3 from below and the radiant heating head 8b for heating the material by radiation from above are performed.

In heating the material by the secondary heating system 8,
The calorific value is adjusted so that the core portion is baked and solidified. In the case of this heating, only the bottom surface of the material is placed on the grill plate 3, and the peripheral surface and the top surface are heated only by the radiation from the radiation heating head 8b. Therefore, when the periphery of the material is surrounded by the frame, the periphery of the material is likely to be harder than the core portion due to heat transfer from the frame, and it is possible to bake softly including the peripheral surface portion. .

When the grill plate 3 on which the material is placed finishes advancing through the secondary heating system 8, the material is properly heated to the core portion to obtain the final product. And this final product is baked plate 3
Is collected by suitable collecting means (not shown) before it is passed through the sprocket 2c and inverted.

In this way, the material is primarily heated in the mold 4 and fired to the extent that the material does not flow out without the mold 4, and then the mold 4 is removed to secondary the material to the core. The final product is obtained by heating. Therefore, as compared with the conventional case where the material is filled in the depressions of the template and heating is continued, the entire surface except the bottom surface can be baked softly.

Further, when it is desired to change the plane shape and size of the product in various ways, it is sufficient to replace only the mold 4 and it is possible to manufacture various kinds of baked confectionery. And
If various forms 4 are provided in the circulation line, okonomiyaki with different shapes and sizes can be manufactured.

Although the production of okonomiyaki was described in the examples, it is needless to say that the method and apparatus of the present invention can be applied to various other flat baked confectioneries.

[0035]

According to the present invention, after heating in a mold to such an extent that the shape of the material on the baking plate is not deformed, the mold is removed and only the bottom portion of the baked confectionery is applied to the baking plate. While finally baking. Therefore, only the bottom portion of the baked confectionery has a higher degree of solidification than the other portions, and the core, surface and periphery of the baked confectionery can be baked evenly and softly.

Further, since a baking plate and a mold for creating a planar shape of a product as a separate body are combined, it is possible to manufacture various kinds of baked confectionery having different shapes and sizes simply by changing the mold, and it is possible to meet the needs. It can easily handle diversification.
