For example, in an apparatus for producing baked foods such as okonomiyaki and hot cakes, materials are mixed to make dough, and vegetables such as cabbage, fruits, etc. are mixed with the dough to be baked.成) Firing of the material is carried out. In particular, okonomiyaki topped with sliced meat or seafood of a certain size has a sense of quality and is widely accepted. Until now, in the case of mass production of okonomiyaki, ingredients such as sliced meat or seafood were manually placed one by one on the spot on the semi-baked dough. However, in the manual method, it is difficult to cope with mass production, and there is a problem in terms of speed and cost. So, a method of mechanizing the operation of placing the ingredients is being considered.

Patent Document 1 discloses a technique for mass-producing okonomiyaki without requiring manual labor by automatically performing the entire process of okonomiyaki. However, in Patent Document 1, although it is disclosed that a space for toppings for placing meat or fish tools is provided, it is not specifically disclosed how to mechanically place the ingredients.

On the other hand, an apparatus for lifting bread dough, hamburger dough before baking, sliced meat, etc. with a robot arm and transferring them is being developed, and its practical use is being studied. For example, in Patent Documents 2 and 3, a technique for transferring an object to be transferred to a predetermined place is disclosed. Patent Documents 2 and 3 describe a transfer method and apparatus having a support plate and a transfer belt. According to the apparatus described in Patent Documents 2 and 3, by changing the rotational direction of the belt, it is possible to lift and move a transfer target and transfer it to another place.

<Operation of Baked Food Manufacturing Equipment>

The operation of the baked food manufacturing apparatus 100 will be described together with the method for manufacturing the baked food of the present embodiment with reference to FIGS. 1 to 6 .

The manufacturing method of the baked food of this embodiment is provided with a material arrangement process, a scraping process, a 1st baking process, a filling material supply process, a batter liquid application process, a turning process, and a 2nd baking process. Each of these steps is performed in this order in the process in which each heating plate P is conveyed in the conveyance direction M by the baked food manufacturing apparatus 100, respectively. For this reason, on each heating plate P, corresponding to a conveyance position, one of the said processes is performed in parallel.

Moreover, in the manufacturing method of the baked food of this embodiment, in a filling material supply process, it heat-processes with respect to a frozen filling material in the middle of conveying a frozen filling material.

Hereinafter, the operation with respect to one heating plate P is demonstrated.

When manufacturing the baked food F6 is started by the baked food manufacturing apparatus 100, first, each heating plate P is preheated by the heating part 6. As shown in FIG. The heating part 6 is a position p1 shown in FIG. 1, ... , it is possible to individually adjust the thermal power at p8.

The temperature of the heating plate P can be set to 170 degreeC - 250 degreeC, for example similarly to normal cooking of okonomiyaki.

(Material arrangement process)

A material arrangement process is a process of arrange|positioning the to-be-baked material F on the heating plate P. That is, it is a process of preparing the to-be-baked material of a predetermined shape.

The control part 4 sends a control signal to the to-be-baked material supply part 1, and supplies the to-be-baked material F0 in a fixed amount from the supply port 10a of each material supply cylinder 10. As shown in FIG. The amount of material to be baked F0 is measured in order to manufacture one baked food F6, respectively, and is extruded downward from each supply port 10a.

The material to be fired (F0) is supplied in a state in which the dough and the filling material in the range of suitable amounts described above are mixed and combined. If the dough and the filling material are mixed and left for a long time, moisture will come out of the filling material and the physical properties of the dough will be changed. In this embodiment, each material supply cylinder 10 is supplied with the fixed quantity which can manufacture at least 1 piece of baked food F6 so that the to-be-baked material F0 may not stay for a long time.

As shown in FIG. 1, the to-be-baked material F0 extruded from the supply port 10a falls on the heating plate P stopped at the position p1 opposing the material supply cylinder 10. As shown in FIG. Since the material to be fired F0 has fluidity, on the heating plate P, it spreads in a substantially circular shape centering on the central axis of the supply port 10a, and the flat material F1 to be fired do. As for the material surface S0" serving as the upper surface of the material to be fired F1, the dough and the filling material as a whole constitute the convex surface of the convex portion thereon. The thickness of the material F1 to be fired is , thickens at the center and becomes thinner at the outer edge. Hereinafter, the maximum thickness of the to-be-fired material F1 is expressed as h0. The outer diameter of the to-be-fired material F1 is the to-be-fired material F0. It becomes an approximately constant value determined according to the size of the fluidity according to the prescription.

However, due to the characteristics of the to-be-fired material F0 including a solid material having a non-uniform shape as the filling material, a certain degree of variation occurs in the thickness distribution and the outer diameter of the to-be-fired material F1. For this reason, it does not become the smooth convex shape typically shown in FIG. 1 in many cases.

When a certain period of time has elapsed after arranging the material to be fired F1, the control unit 4 sends a control signal to the heating plate conveying unit 5, and moves each heating plate P in the conveying direction M by a predetermined pitch. is moved Thereby, the heating plate P at the position p1 is moved to the position p2. The to-be-fired material F1 is moved to the position where the center becomes just below the shaping|molding part 2 . 1 shows a state in which the material to be fired F2 disposed on the heating plate P2 is moved to the position p2 in the material arrangement step immediately before the material to be fired F1 is disposed.

With this, the material arrangement process is finished.

(First firing process)

1 shows a state in which the material to be fired F1 is being fired while being moved to the position p3.

The material to be fired is fired from the bottom at least between the positions p2 to p5 by the heating unit 6 (first firing step). In this process, the to-be-fired material F1 is injected|thrown-in, and the shaping body F3 in which the outer peripheral part of the to-be-baked material F on which the filling material 11 was placed was further heated, and at least the contact surface with the heating plate P This is a step of forming the fired intermediate fired body F4.

The target temperature of the heating plate P in this process is about 170 degreeC - 250 degreeC. The firing temperature and firing time are adjusted according to the firing state of the intermediate fired body F4.

(Ingredient supply process)

The filling material supply step includes a filling material placing step of placing the frozen filling material 11 on each of the plurality of filling material conveying units 73 (support plate 22), and heating the frozen filling material 11 to partially It has the heat treatment process to thaw, and the stuffing material placing process which places the stuffing material 11 after heat processing on the to-be-baked material F2, and it is performed in parallel with a 1st baking process. Here, the filling material 11 is supplied one by one on the material surface S0", which is the upper surface of the to-be-fired material F2 on the heating plate P, while heat-treating the filling material 11. The flow is shown in Fig. 6 shows.

((Ingredients loading process))

First, the control part 4 moves the some filling material conveying part 73 in the filling material supply part 7 in the conveyance direction N by driving a conveyor (not shown). During movement, on the support plate 22 of each filling material conveying part 73, the frozen filling material 11 is put on one by one. The operation|work which puts the filling material 11 on the support plate 22 may be the operation|work by the robot 35 controlled by the control part 4, for example, and may be performed manually by the person 36.

((Heat treatment process))

In addition, the control unit 4 sends a control signal to the steam generator 71 to heat the supplied water to generate steam, and supply steam to the heat processing space K of the preheating processing unit 72 . . The control unit 4 adjusts the amount of water vapor supplied from the water vapor generating unit 71 to the preliminary heat treatment unit 72, and sets the heat treatment temperature (temperature of the heat source) in the water vapor atmosphere in the heat treatment space K to 60 Control to be within the range of ℃ or more and 120℃ or less. According to this heat treatment temperature, the time required for the heat treatment with respect to the filling material 11 in a frozen state is set within the range of 1 second or more and 15 seconds or less.

Next, the control part 4 transmits a control signal to the filling material conveying part 73, and heat-processing with respect to the filling material 11 in a frozen state. The control unit 4 conveys the filling material 11 placed on the support plate 22 through the covering member 23 to the preheating processing unit 72 by the filling material conveying unit 73 , and transporting the inside of the housing 24 . It passes while moving along the opening (25). A high-temperature steam atmosphere is formed in the housing 24 of the pre-heating treatment unit 72, and when the filling material 11 on the support plate 22 is exposed to the heated steam, the surface of the filling material 11 instantly falls in love. is matched The time required for the heat treatment is in the range of 1 second or more and 15 seconds or less. The heat treatment time corresponds to the time during which the filling material conveying unit 73 passes through the housing 24 of the preheating treatment unit 72 . That is, in the present embodiment, the surface of the filling material 11 is anti-thawed while the filling material conveying unit 73 supporting the filling material 11 passes through the heat processing space K of the preheating processing unit 72 . it is made to be

The surface of the filling material 11, which is in a semi-thawed state by heat treatment, does not dry due to the adhesion of water droplets, and does not become hard.

((Ingredient material placement process))

Next, the control part 4 continuously moves the filling material conveying part 73 along the conveyance direction N, and conveys the half-thawed filling material 11 over the to-be-baked material on the predetermined heating plate P. . During the movement, it is preferable that the semi-thawed state of the filling material is maintained as much as possible, and it is preferable to move the filling material in the shortest possible time.

The control part 4 temporarily stops the filling material conveyance part 73 which reached|attained the predetermined|prescribed heating plate P, and moves it to a predetermined place on the conveyance direction M by a moving means. By the operation of the pressing means 29, each pressing portion 29A enters the round hole 14 formed in the housing 21 of the filling material conveying portion 73 and is pushed toward the front wall 21a. When the supporting plate 22 is pushed toward the rear wall 21b side, the supporting plate 22 is displaced from the advanced position to the retracted position. The covering member 23 is retracted to the rear side so as to be wound around the front end of the support plate 22 . The filling material 11 in a semi-thawed state placed on the support plate 22 does not follow the movement of the support plate 22, but is extruded toward the tip side of the support plate 22, maintaining a horizontal posture, the support plate 22 falling from above

In this way, by continuously performing the filling material placing step, the heating treatment step, and the filling material placing step, in the approximate center of the material surface S0″ of the material to be fired F2 on the predetermined heating plate P2, it is half-thawed. The filling material 11 in a state is placed.

(Battery solution application process)

Next, the control unit 4 sends a control signal to the batter liquid supply unit 8, and the filling material 11 in a semi-thawed state is placed on the material surface S0" of the baking material F2 on which the filling material 11 is placed. 11) and the batter liquid 15 for binding the material to be fired (F2) is supplied.

(raking process)

Next, a scraping process is performed. This process is a process of shaping the outer periphery of the to-be-baked material F on which the filling material 11 on the heating plate P was placed, and pressing the dough supplied in the shape of a mountain. Moreover, in this process, an outer peripheral part can also be adjusted to circular shape. In this embodiment, this process is performed by the shaping|shaping part 2, for example. In addition, when thickness is not required, this process is unnecessary.

For example, the outer periphery of the to-be-fired material F is scraped by a shaping spatula, a shaping mold, etc. to shape an outer peripheral shape, and the thickness is adjusted as needed by a pressing member etc. Thereby, the disk-shaped fixed body F3 is formed.

Since the heating from the heating plate P is advancing the molded object F3, the lower surface which contacts the heating plate P is baked gradually. However, the material surface S0", which is the upper surface of the shaped body F3, has not yet been fired.

In this way, when the shape of the shaped body F3 is stabilized to some extent, the control unit 4 sends a control signal to the heating plate conveying unit 5, and each heating plate P is moved at a constant pitch in the conveying direction M. move as much Thereby, the heating plate P at the position p4 is moved to the position p5.

With this, the scraping process is finished.

(flip process)

Next, an overturning process is performed.

In this step, the above-described molded body F3 is continuously heated from the heating plate P by the inversion unit 3, and the intermediate fired body F4 in a state in which the first firing surface S1 (contact surface) is formed on the lower surface. ) is a process of arranging upside down on the heating plate P at the position p6. This process is started when this heating plate P is moved to the position p5 after the intermediate|middle sintered body F4 is formed from the mold body F3.

First, the control unit 4 sends a control signal to the reversing plate moving mechanism 34 to horizontally move the reversing plate 30 to the upstream side in the conveying direction M, and the distal end of the heating plate at the position p5 ( P) It is inserted between the first firing surface (S1) and the heating plate (P) of the intermediate fired body (F4) above, and then is lifted up by the inversion plate (30). Previously, the control unit 4 moves the heating plate P at the position p5 (the heating plate P without the intermediate fired body F4) to the position p6.

Next, the control unit 4 inverts the intermediate fired body F4 by rotating the inverting plate 30 above the heating plate P to invert the intermediate fired body F4 over the heating plate P at the position p6. place it

As for the fallen intermediate fired body F4, the heating plate P and the whole material surface S0" on which the filling material 11 is placed are brought into contact, and the first firing surface S1 is turned upward, and is turned over. lose

(Second firing process)

Next, a second firing step is performed. This step is a step in which the inverted intermediate fired body F5 in which the intermediate fired body F4 is turned over is heated by the heating plate P and fired.

When the inversion intermediate fired body F5 is placed on the heating plate P at the position p6, it is immediately heated, so that the material surface S0″ is fired gradually.

The inversion intermediate fired body F5 is disposed on the heating plate P for a time required for the material surface S0″ to be fired. In this embodiment, as an example, the heating plate P is moved to the position p7, and the heating plate When the tact time of the movement of (P) is completed, the firing of the contact surface with the heating plate P in the inversion intermediate fired body F5 is finished, and the second fired surface S2 is formed.

As described above, the second baking process is completed, and the baked food is manufactured.

Since such a process is performed sequentially and in parallel on each heating plate P, 6 baked foods are produced intermittently for every fixed takt time.

Baked food is moved from the heating plate P to a suitable cooling place in this embodiment. After cooling to some extent in a cooling place, a refrigeration process or a freezing process is implemented.

As a means for refrigeration or freezing, a suitable conventional technique can be applied. For example, a spiral cooler, a wagon cooler, a flexible cooler, an aluminum fin coil type refrigerator, a unit cooler type refrigerator, etc. are applicable. Freezing can be performed rapidly using a spiral cooler, for example, at about -30°C.

The frozen baked food F6 can be thawed and cooked in a microwave oven to reproduce a freshly baked state and provide it to the table.

According to the manufacturing method of the baked food of this embodiment using the baked food manufacturing apparatus 100, since the filling material 11 dropped from the support plate 22 is in a semi-thawed state, the material surface S0 of the to-be-baked material F2 "), it is possible to place it in a predetermined position without being bounced. In this embodiment, when conveying the filling material 11 by the filling material supply part 7, the frozen filling material 11 is turned on in a steam atmosphere. In this way, the surface of the filling material 11 can be partially thawed. Previously, when the frozen filling material 11 is dropped onto the material surface S0" of the material to be fired F2 as it is, it is hardened by freezing. The filling material 11 is thrown away, and cannot be placed on the material surface S0" of the material to be fired F2, or it may deviate from a predetermined placement position. In contrast, in this embodiment, the frozen filling material ( By semi-thawing 11) in advance, flexibility can be given to the filling material 11, and the filling material 11 dropped from the support plate 22 is placed at a predetermined position on the material surface S0" of the material to be fired F2. It is possible to wit Moreover, since the half-thawed filling material 11 does not adhere to an apparatus, the baked food F6 can be mass-produced efficiently.

In addition, in this embodiment, water vapor|steam was used for the heat processing of the filling material 11 of freezing. Since heat is not locally applied by arranging the frozen filling material 11 in water vapor, it is possible to uniformly thaw the surface of the filling material 11 . Moreover, since water vapor|steam adheres to the surface of the filling material 11, it does not dry and harden, and the original quality of the filling material 11 can be maintained.

In addition, in this embodiment, the filling material 11 is not completely thawed, but it is made into a semi-thawed state. Therefore, there is also no fear that the filling material 11 adheres to the covering member 23 surrounding the support plate 22 and becomes difficult to fall off, and workability in the step of placing the filling material 11 can be improved.

Moreover, in this embodiment, by dripping the batter liquid 15 on the to-be-baked material F2 on which the filling material 11 was mounted, it can suppress that the filling material 11 comes off when implementing a turning-over process. .

In addition, in this embodiment, the robot 35 may be sufficient as the operation|work which puts the filling material 11 in a frozen state on the support plate 22 of each filling material conveyance part 73, for example, and the person 36 It is assumed that it is also possible to perform it manually. In the past, the filling material was placed manually on the material to be fired on the heating plate P, but in the present invention, even if it is manually done, it can be placed on the support plate 22 at room temperature, so that the worker can work under an appropriate temperature environment. Being able to do it is also excellent.

Next, the result of having investigated the mounting condition of the filling material 11 on the material surface S0" of the to-be-fired material F2 is demonstrated.

[Example 1]

Table 1 compares the state of the filling material for each heat treatment time for the filling material 11 under the conditions shown below, and the evaluation when the filling material 11 is placed on the material surface S0" of the material to be fired F2 indicates

(Example of processing conditions)

Heat treatment temperature (atmospheric temperature in warehouse): 60℃

The temperature near the sliced meat: 80 degrees Celsius

Product temperature: -4℃ before heating → 15℃ after heating

Passing time: 9.5 seconds

As shown in Table 1, when the surface temperature of the filling material 11 is frozen at -20°C, the filling material 11 is repelled from the material surface S0" of the material to be fired F2 and placed on the surface. It was not possible, or it deviated from a predetermined position.

Moreover, when heat processing is performed for about 5 seconds and the surface temperature of the filling material 11 becomes 5 degreeC, only the surface will be in the thawed state. In this case, the filling material 11 was satisfactorily placed in the central position on the material surface S0" of the to-be-fired material F2.

Moreover, when heat processing is performed for about 15 seconds and the surface temperature of the filling material 11 becomes 10 degreeC, only the surface will be in the thawed state. In this case, the filling material 11 was satisfactorily placed in the central position on the material surface S0" of the to-be-fired material F2.

However, when the heat treatment is performed for about 30 seconds and the surface temperature of the filling material 11 reaches 40°C, only the tip is thawed. In this case, it was not possible to mount at the central position on the material surface S0" of the to-be-fired material F2 in some cases.

In addition, when the heat treatment is performed for about 30 seconds and the surface temperature of the filling material 11 reaches 60°C, about 1/3 of the filling material 11 is thawed, and the material surface S0" of the material to be fired F2 is ) could not be placed in the central position because of the fact that the filling material 11 had adhered to the device by thawing too much.

From the above, when the heat treatment is performed under the predetermined temperature conditions, the heat treatment time for the frozen filling material 11 is preferably within the range of 5 to 15 seconds, and heat treatment to thaw only the surface of the filling material 11 is performed. to do it Thereby, the filling material 11 can be mounted efficiently on the central position of the material surface S0" of the to-be-baked material F2.

[Example 2]

Next, the result of examining the placement state of the filling material 11 after the overturning process according to the presence or absence of the batter liquid 15 is demonstrated.

(1) In the case of the intermediate sintered body F4 in which the batter liquid 15 could not be dripped onto the surface on which the filling material 11 was placed, the drop of the filling material 11 was found to be about 5% after the overturning process.

(2) In the case of the intermediate sintered body F4 in which the batter liquid 15 was dripped by 5 ml on the surface on which the filling material 11 was placed, there was no drop of the filling material 11 after the overturning step.

(3) In the case of the intermediate fired body F4 in which 10 ml of the batter liquid 15 is dripped on the surface on which the filling material 11 is placed, there is no drop of the filling material 11 after the turning over step, but the batter liquid 15 Since there is a large amount of dripping, it takes time to bake the batter liquid 15, and the production time per unit is prolonged.

From the above, about 5 ml of the dripping amount of the batter liquid 15 in manufacture of okonomiyaki is good, and it adjusts suitably according to the size of the intermediate|middle baked body F4, the filling material 11, etc. The dripping amount of the batter liquid 15 is 1 ml or more and 15 ml or less, for example. It is preferable that they are 1 ml or more and 10 ml or less, and, as for the dripping amount of the batter liquid 15, 3 ml or more and 8 ml or less are more preferable. By dripping the batter liquid 15 on the intermediate fired body F4 on which the filling material 11 is placed and then turning it over, the filling material 11 can be bound to the surface of the intermediate fired body F4.

In this embodiment, the intermediate fired body F4 is turned over after the batter liquid 15 is dripped. ) may be provided with a calciner capable of calcining the surface in a non-contact manner, and the batter liquid 15 may be calcined before performing the overturning step. Thereby, after turning over the intermediate calcined body F4, the time for calcining the batter liquid 15 dripped on the surface can be shortened.

As mentioned above, although preferred embodiment which concerns on this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to the example concerned. It is clear that it is within the scope of the technical idea described in the claim by those skilled in the art, and it is clear that various changes and modifications can be conceived, and it is understood that it belongs to the technical scope of this invention also about them of course. You may combine the structures of each embodiment suitably.

For example, the manufacturing process sequence of the baked food is not limited to the process sequence described above, and can be appropriately changed. For example, it does not specifically limit about which timing to implement a scraping process.

Moreover, you may warm the support plate 22 on which the filling material 11 of freezing is mounted, for example. In this case, as in the case of exposure to water vapor, it is preferable to warm to a temperature such that the surface of the filling material 11 is thawed.

In the above-mentioned heat treatment, only the surface of the frozen filling material needs to be thawed, and it may be a method of exposure to heated steam, a method of passing through a bath or hot water, or a method of thawing in a microwave for a short time. Although the method of irradiating to heated water vapor|steam is suitable since it can prepare easily in a normal factory etc., it is not specifically limited.

In addition, in this embodiment, by horizontally moving the support plate 22 on which the filling material 11 is placed, the filling material 11 is extruded from the top of the support plate 22 and dropped on the material to be fired. On the material to be fired, You may drop it by giving recoil to the support plate 22, or making the support plate 22 incline.
