Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a manufacturing apparatus suitable mainly for manufacturing bean paste buns, especially what is called "Imakawa ware"("large format ware" or "rotary ware"), and mainly The present invention relates to a heating device used in the manufacturing apparatus.

(Prior Art) Manju with bean paste, for example, the so-called "Imakawa-yaki", is a flow-like dough prepared by mixing wheat flour as a main component into two surfaces 1A, 1B (each surface). Is called half)
In the recess 2 formed in the half-face 1A of the copper plate or the like made of copper plate, an amount of about 2/3 of the recessed portion 2 is poured off, and when the surface is baked to a degree of hardness, its center Put the red bean paste on the other side and the other half of the baking mold 1B
About 1/3 of the dough is poured into the above, and the semi-finished product on the half side 1A side where the bean paste is put (half of the product containing the bean paste) is almost baked, and the semi-finished product is recessed on the half surface 1A. Take out from 2, and turn it upside down to cover the upper half-finished product (half of the product without bean paste) on the other half surface 1B side. Then, in this state, the surface on the side of the other half surface 1B and the entire inside are baked to such an extent that they are sufficiently treated (alpha-ized) to complete the product.

One cycle of the manufacturing work is completed in the above series of steps, but since the manufacturing work is generally performed continuously,
After covering the above-mentioned semi-finished product with bean paste on the top of the semi-finished product on the other half surface 1B side, the dough for the semi-finished product with bean paste for the next cycle is dropped onto the empty half surface 1A. Then, the next manufacturing cycle is started.

By the way, as a feature of the above product, it is the most preferable product that the surface of the product is burnt in a fox color and the inside thereof is castella-shaped in a completed state.

Further, the surface of the product is required to be smoothly finished without forming pores due to bubbles or the like. The pores such as air bubbles impair the passage of heat to the inside and significantly impair the appearance of the product.

In order to meet the above-mentioned requirements for products,
As shown in FIG. 4, a gas stove 4'having a size corresponding to one half surface is placed below a baking mold 1 composed of two surfaces 1A and 1B in which a plurality of concave portions are arranged in line. A device is used which is slidably arranged below the mold 1 and can selectively supply the flame to only one half surface (1A or 1B) of the baking mold.

Then, using the above apparatus, in order to produce a good product as described above, the temperature of the baking mold when the dough is cast off is approximately 110 ° C to 145 ° C (referred to as a low temperature range), and After the runoff, the baking temperature is 170
℃ ~ 210 ℃ (high temperature range) must be raised rapidly, and the temperature of this baking mold is different from that of the bean paste, even though the specific heat of the object to be baked is different. Both half and half of the fabric must be satisfied.

Therefore, at the time of manufacturing, an operator appropriately slides the gas stove 4'below the baking mold 1 between the one half surface 1A and the other half surface 1B as needed, and at the same time, the gas flame It is the current situation that the size must be adjusted frequently.

In addition, the temperature of the baking mold is currently empirically determined by observing the state (reaction) when the dough or the like flows down or the state of bubbles generated from the dough after the dough or the like flows down.

Further, in the case of continuous manufacturing work, when shifting to the next manufacturing cycle as described above, it is required to quickly reduce the temperature from the high temperature range to the low temperature range.

(Problems to be Solved by the Invention) As described above, this manufacturing work is extremely difficult because the position of the gas stove and the flame of the gas must be adjusted while observing the firing state of the dough and the like. .

For this reason, considerable training and the personal talent of the worker are required until a good product can be manufactured.

In addition, as mentioned above, it is necessary to use a gas stove with large calories in order to raise the baking mold from a low temperature region to a high temperature region within a predetermined time. Gas stove regulations are tightened,
These are becoming difficult to use. Generally, it is conceivable to use an electric heating type so-called sheathed heater as a heat generating device instead of the gas stove, but such a sheathed heater cannot obtain the calories required for the above production.

The present invention has been made in view of the above situation, and provides a bean bun manufacturing apparatus that can be easily controlled by a control device without using a gas stove, and a heating device that can be used in this manufacturing device. The purpose is to do.

(Means for Solving the Problem) A steamed bun manufacturing apparatus according to the present invention is a steamed bun manufacturing apparatus in which baking molds are arranged in a row above and a calorie controllable heating device is arranged below the baking dies. There, the bottom of the baking mold is coated in black, and the heat generating device is composed of a halogen lamp provided corresponding to the row of the baking mold, and it is located below the halogen lamp and reflects upward. A reflecting plate having a trough is formed, and the space below the baking mold where the halogen lamp and the reflecting plate are arranged is partitioned from the outside, and if necessary, a ventilation hole communicating with the outside is provided on the partitioned wall surface. It is characterized by that.

Further, in the above structure, in the halogen lamp, tungsten is wound in a heat-resistant straight transparent thin tube so that both ends are densely roughened at the center, and both ends of the transparent thin tube are covered. It is characterized in that it is hermetically sealed and a small amount of a halogen substance is enclosed therein together with an inert gas.

(Operation) However, the steamed bun manufacturing apparatus having the above configuration effectively heats the baking dies whose bottom surface is coated in black by the radiant heat from the halogen lamp from the bottom, thereby generating a large calorie required for baking. The air is supplied so that it concentrates on the rows of the baking dies, and when it is necessary to quickly lower the temperature, the halogen lamp is turned off and, if necessary, the ventilation holes formed in the partition walls in the space below the baking dies. By communicating with the outside, the heat of the space can be released to the outside, and the required low temperature region can be quickly obtained.

When using the above "Imakawa Yaki", use the above halogen lamps and divide them into two groups corresponding to half of the baking mold. If the heat generation is controlled according to the above, and the other halogen lamp group is controlled to perform heat generation in cooperation with the above-mentioned bean jam dough control cycle for baking dough without bean jam, the surface will be fox-colored inside. Can continuously produce good castella-shaped "Imakawa Yaki".

Further, since the heating device is a halogen lamp, it generates stable and extremely large radiant heat over a long period of time, and both end portions generate a large amount of heat per unit length as compared with the central portion, so the bun manufacturing apparatus In this case, both the periphery of the baking mold, which has a large amount of heat radiation to the outside, and the central portion, which has a small amount of heat radiation to the outside, are uniformly heated.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing the internal structure of the “Imakawayaki” manufacturing apparatus according to the present embodiment with the half surface raised, and FIG. 2 shows the structure of the halogen lamp used in FIG. FIG. 3 is a plan view showing the operation state of the halogen lamp on each half surface of the baking mold of the apparatus and the operation diagram of the work corresponding thereto.

In FIG. 1, reference numeral 1 is a baking plate made of a copper plate.
Has a large number of flat circular recesses 2 in which portions corresponding to the shape of the upper half or the lower half of the upper and lower joints of "Imakawa Yaki" are depressed downward (in Fig. 1, 7 rows in horizontal and 6 columns in vertical). Total 4
2) are formed. As shown in FIG. 1, this baking mold 1 is divided into half surfaces 1A and 1B at the center of the left and right (upper and lower when viewed from the operator side; left and right in the figure). The bottom surface 1a of the baking mold 1 is coated with black ceramic.

Under each half surface 1A, 1B of the baking mold 1, there is formed a box-shaped body 5 composed of a peripheral wall and a bottom surface and opened upward. That is, the box-shaped body 5 is configured by disposing the peripheral wall 5A and the reflection plate 3 forming the bottom surface on the bottom portion surrounded by the peripheral wall 5A shown in FIG. Then, by placing the baking mold 1 above the open box-shaped body 5, a space having a partition wall is formed below the baking mold 1. Further, a gap (ventilation hole) S for ventilation is formed between the baking mold 1 and the lower peripheral wall 5A,
A baking mold 1 is placed on the peripheral wall, and a plurality of ventilation holes 6 are also formed in a valley portion 3a of a reflecting plate 3 described later.

In the case of the present embodiment, the reflection plate 3 is formed in a mountain shape in which the bottom surface 2a of the recess 2 of the baking mold 1 is located above the valley portion 3a of the reflection plate 3. The surface of the reflector 3 is gold-plated so as to obtain high reflection efficiency.

A heating device, that is, a straight halogen lamp 4 having a small diameter is arranged in the space of each valley 3a of the reflection plate 3.

Therefore, in the case of the present embodiment, the half surfaces 1A and 1B of each baking mold 1
A total of six halogen lamps 4 will be arranged in two groups so that three lamps each constitute one group.
Then, terminals for supplying electric power are formed at both ends of each halogen lamp 4, and these terminals turn on the electricity for each group.
It is connected to the power supply side via a control device (not shown) so that it can be turned off.

As shown in FIG. 2, the halogen lamp 4 is composed of a straight transparent small-diameter tube 4a made of heat-resistant quartz glass on the outside, and is densely roughened in the center at both ends inside. The tungsten 4b is disposed in a wound state, and the both ends of the transparent small diameter tube 4a are hermetically sealed and an inert gas and a small amount of a halogen substance are sealed inside.

Then, the control device operates in the order and strength (voltage) as shown in the device operation diagram of FIG. 3 to each half surface 1A, 1B of the baking mold 1.
The halogen lamp 4 group on the side is sequentially energized or interrupted. That is, this manufacturing apparatus is controlled by the control device so as to repeat the series of operating states described in "Step 1" to "Step 4" below.

In the "step 1" state, energize the four groups of halogen lamps (three halogen lamps in this embodiment) on the half surface 1A side of the baking mold 1 on which the bean paste is placed so that the strength is "weak". At the same time, the halogen lamp group 4 (three halogen lamps in this embodiment) on the half surface 1B of the baking mold 1 on the side where the bean paste is not placed is energized so that the strength becomes "strong". The strength of the energized state is “weak”, and the strength is “strong” when the halogen lamp group 4 energizes at a voltage value that brings the baking mold 1 to the low temperature range (110 to 145 ° C.). Similarly, energization is performed at a voltage value that brings the baking mold 1 to a high temperature range (170 to 210 ° C.).

Then, when this device is in this state, the half surface 1A of the baking mold 1
Becomes a desired low temperature range. Therefore, in this state, the worker may sequentially drop the dough into each recess 2 of the half surface 1A. Also, at this time, half-face 1B is in a high temperature range, and in the concave portion 2 of half-face 1B, the final stage baking is performed for the product that was in the product state (the state in which "Imakawa Yaki" was vertically stacked) in the previous cycle. It is carried out. Therefore, in this "step 1" state, the manufacturing process of the previous cycle and the manufacturing process of the next cycle are performed in a state of overlapping.

Then, when the dough is completely washed off in the state of "step 1" as described above, the apparatus shifts to the next "step 2". At this time, in the concave portion 2 where the dough was first dropped,
The surface of the dough is baked to a predetermined hardness, and the apparatus shifts to the next "step 2".

In "Step 2", the intensity of the halogen lamps 4 on the half surface 1A side of the baking mold 1 is changed to "strong", and the half surface 1A is in the high temperature range. Then, in this state, the operator puts the bean paste into the dough in the concave portion of the half surface 1A. Further, in this "step 2", the intensity of the halogen lamp 4 group on the other half surface 1B side becomes "weak", and the temperature of this half surface 1B gradually decreases. At this time, the product is completed on this half surface 1B, the product is recovered from the concave portion 2 of this half surface 1B, and the previous manufacturing cycle is ended.

Next, the process proceeds to "step 3". In this "Step 3", the halogen lamp 4 group on the half surface 1A side of the baking mold 1 is "strong".
In this state, the baking of the semi-finished product containing the bean paste will continue. Further, in this "step 3", the halogen lamp 4 group on the other half surface 1B is in the "OFF" state, and this half surface 1B is quickly lowered to the low temperature range.
Then, while the baking of the semi-finished product on the half surface 1A is continued, the dough is made to flow into the concave portion 2 of the half surface 1B.

Next, shift to "Step 4", the halogen lamp 4 group on the half surface 1A side of the baking dies 1 becomes "off", and the other half surface
The intensity of 4 groups of halogen lamps on the 1B side changes to "strong". In this state, the semi-finished product on the half surface 1A side (semi-finished product on the side containing bean paste) has been almost completely baked, and this semi-finished product is turned upside down (the side where the bean paste is exposed faces downward ), And put it on the other half 1B on the baking material in sequence.

And when the last one has been placed, half 1A of baking mold 1
The recessed part becomes empty and is ready for the next manufacturing cycle. That is, the state returns to the above-mentioned "step 1", and the manufacturing is continued in the series of steps described above.

In this manufacturing apparatus, when the halogen lamp group 4 is in the "strong" energization state, it is inferior to the conventional gas stove due to the radiation heat from the halogen lamps and the effect of the black ceramic coating provided on the bottom surface of the baking mold 1. No calories can be supplied to the baking mold. In addition, the rapid decrease in temperature from the high temperature range to the low temperature range uses the convection effect in the space below the baking mold (here, warm air rises upward) to make the valley of the reflector plate described above. It is made to escape from the ventilation hole 6 formed in the portion to the outside through a gap S formed between the baking mold 1 and the peripheral wall therebelow.

Therefore, in the present manufacturing apparatus, it is possible to obtain the rapid temperature rise and fall required for bean paste buns such as "Imakawa Yaki" with the above-mentioned configuration.

Further, the control device of the manufacturing apparatus is configured so as to be able to adjust the cycle of the series of manufacturing steps, and therefore, from the expert to the beginner, the cycle time suitable for the skill of the person is manufactured. Is possible. That is, since the skilled worker and the beginner have different work speeds such as the flow of dough into each recess or the supply of bean paste, the transition time to the next step is different, so the cycle time is adjusted according to each work speed. It is configured to be able to.

Furthermore, in the case of this manufacturing apparatus, for each half surface of the baking mold,
Since the independent space is formed thereunder, the temperature of one half surface is not affected by the other half surface, and each can obtain the most suitable temperature for each process.

The manufacturing apparatus configured as described above and having the function is as follows.
If the cycle time of the above series of steps is adjusted according to the skill of the user, the control device can control the baking mold temperature without requiring extremely difficult work such as the size of the flame or the movement of the gas stove. Because it is controlled, even beginners can produce the manju with the best quality, which is the same as the one baked by the expert.

(Effects of the Invention) Since the steamed bun manufacturing apparatus according to the present invention can obtain a large calorie without using a gas stove, the manufacturing apparatus can be implemented without any problem even in a place to which the Fire Service Act is severely applied. Therefore, in-store manufacturing with a great advertising effect can be carried out in a department store building or in an underground mall.

Further, unlike a gas stove, no combustion gas is generated, so that the working environment is significantly improved compared to the conventional environment.

Further, since this manufacturing apparatus is heated by the electric heating device, it is possible to easily perform accurate control by the control device, and therefore, a semi-automatic manju-manufacturing apparatus for filling with bean paste is provided as in the above embodiment. In this case, since the control device controls the complicated temperature of the baking mold, even a beginner can manufacture the manju bun with the same best quality as the expert.

Since the apparatus of the present invention is provided with the reflection plate having the valleys corresponding to the rows of the baking dies, the rows of the baking dies can be intensively heated, and the baking dies can be quickly heated to the baking temperature. You can

Furthermore, since the above-mentioned heating device gives calories to the periphery and the center of the baking mold so as to correct the difference in the amount of heat radiation, each part is considered in consideration of the flame and the amount of heat radiation as in conventional manufacturing equipment. It is not necessary to irregularly change the order of processing or the order of product recovery of the semi-finished products in the recess located at.
