Description

The present invention relates to a Baumkuchen baking machine that bakes dough.

A conventional Baumkuchen baking machine, for example, as disclosed in Japanese Utility Model Publication No. 46-4878, Japanese Patent Publication No. 7-24532, etc., has a pair of left and right opposing shafts intermittently rotatable inside the baking furnace. and a horizontal rolling pin that is detachably inserted between the left and right sides of both circular drums, and when the rolling pin reaches the lowest position and temporarily stops, the dough is wound from the dough plate. After being coated, the dough is baked while rotating and revolving inside the baking furnace. By repeating such a cycle, the basic structure was to manufacture Baumkuchen in which the dough was layered in the shape of tree rings.

However, in any of the above known techniques, the dough plate for applying the dough to the rolling pin is located at the entrance of the baking furnace, and the entrance communicates with the innermost part of the baking furnace in a fully open state. It is said that it is impossible to obtain a uniform thickness and quality that is rich in expansion and moistness (wetness), because the dough is already heated in the dish and the heating temperature is uneven. I had a problem.

Japanese Patent No. 3686671, for example, is known as a technique related to conventional Baumkuchen baking aimed at solving this conventional problem.
FIG. 13 is a diagram showing the basic structure of the Baumkuchen baking machine disclosed in Japanese Patent No. 3686671. As shown in FIG. As shown in FIG. 13, the baking furnace B can be partitioned into a dough coating zone Z1 on the entrance side where the dough dish 72 is present and a dough baking zone Z2 on the inner and inner side where the gas burners 8 and 9 as heat sources are present. A first partition shutter 43 and a second partition rotary shutter 45 are installed, and the first partition shutter 43 and the second partition rotary shutter 45 are synchronized with the intermittent rotary drive of the rotary drum 14 to cause the rolling pin 16 to revolve. By advancing and retreating so as to block the locus R, the dough baking zone Z2 is sealed while the rotary drum 14 is temporarily stopped to prevent heat radiation therefrom, while the dough is also heated when the rotary drum 14 is rotating. The baking zone Z2 is designed to open in communication with the dough coating zone Z1. Since the first partition shutter 43 has a margin in the lower space of the baking machine, it can be operated vertically and vertically. Therefore, it is a rotating shutter type.

This configuration and operation are the basic configuration and operation of the prior art.
In a general Baumkuchen baking machine, there are six stopping places in the intermittent movement along the revolution orbit. In FIG. 10, the stop positions are P1 to P6. The roles played in the Baumkuchen baking process at the respective stop positions P1 to P6 are as follows.
In the baking process of Baumkuchen, P1 is dough making, P2 is dough molding, P3 is steaming baking, P4 is main baking, P5 is coloring baking, and P6 is preparation.
Among these, there are four stop positions from P3 to P6 in the dough baking zone Z2 that can be heated and baked. In particular, due to the structure of the furnace, there are two main firing points: P4, which is the main firing, and P5, which is the coloring firing.
The Baumkuchen baking machine, due to its structure, bakes while alternately immersing the dough with a stick suspended horizontally on a rotating drum and baking the dough while rotating the dough around the immersed rod. In general, 15 to 30 layers of baked dough are piled up.

Japanese Utility Model Publication No. 46-4878 Japanese Patent Publication No. 7-24532 Japanese Patent No. 3686671

The first issue is to shorten the firing time by improving the firing process.
As mentioned above, in the baking process of Baumkuchen, there are 6 processes of P1 dough making, P2 dough molding, P3 steaming baking, P4 main baking, P5 coloring baking, P6 preparation preparation. is one cycle, and the dough is baked while repeating the cycle to produce a multi-layered baked confectionery. This cycle is repeated for 15 to 30 cycles to bake Baumkuchen having 15 to 30 layers. Therefore, there is a problem that it takes a long time to bake one Baumkuchen.
In addition, in order to bake moist and soft Baumkuchen, it is necessary to bake one cycle for the required time while maintaining the required temperature and humidity in the baking process. 30 cycles should be repeated. For this reason, the baking time required to bake moist and soft Baumkuchen was unavoidably long.
Here, if you try to solve it by simply applying a large amount of heat to shorten the baking time, not only will uneven baking occur, but the surface of the Baumkuchen will be baked too hard. In recent years, moist and soft baumkuchen has become popular, and since it has a refractory temperature as a kiln of a baking machine, it cannot be solved simply by throwing in a large amount of heat.
Here, the inventors realized that if the baking process consisting of these six processes could be improved, the baking time of Baumkuchen could be shortened.

The second issue is the improvement of the firing space in the firing operation.
The baumkuchen baking machine is an automatic machine, but in order to proceed with the baking of baumkuchen, workers are required during operation, and they are responsible for some molding work. In the Baumkuchen baking process described above, it is necessary to stand in front of the dough application zone Z1, which is an open space in front of the Baumkuchen baking machine, and assist the operations of dough application P1 and dough molding P2. The depth of the dough in the dough tray is important in the dough application process of P1, and it is necessary to frequently supply the dough. Also, in the dough forming process of P2, it is necessary to check the state of the dough on the rods lifted from the dough tray, and shape the dough on the surface of the Baumkuchen with a spatula or the like. It is difficult to automate this P2 dough molding process in order to finish the baking naturally and neatly, and the quality of baking is better if an operator intervenes.
However, the standing position of the manufacturing worker who operates the baking machine is in front of the dough coating zone Z1, which is an open space in front of the Baumkuchen baking machine, and is an open part of the furnace operating at high temperature. It is difficult to shield the heat, and the heat dissipation inevitably increases. There is also a limit to the refractory temperature of the production workers who operate the calcining machine, and it was necessary to improve the work space.
Here, the present inventors realized that if the structure of the Baumkuchen baking machine can be improved, the baking space of the Baumkuchen baking machine and the work environment for workers can be improved.

The third issue is to improve the baking ability (firing potential) in the Baumkuchen baking machine.
As described above, in the conventional Baumkuchen baking machine, there are four stop positions from P3 to P6 in the dough baking zone Z2 where the dough can be heated and baked. In particular, due to the structure of the furnace, there are two main locations facing the heat source: P4 main firing and P5 coloring firing. In other words, there were only two stop positions among the six stop positions where the potential for firing could be exhibited.
Here, the present inventor believes that if the structure of the Baumkuchen baking machine can be improved, the number of stop points in the furnace of the Baumkuchen baking machine that are close to the heat source where baking can be performed sufficiently can be increased, and the baking potential of the entire Baumkuchen baking machine can be improved. I noticed that there is

Therefore, in view of the above problems, the present invention improves the structure of the furnace itself, realizes moist and soft baking, shortens the baking time, improves the working environment for workers, and improves Baumkuchen baking. It is an object of the present invention to provide a Baumkuchen baking machine with a new furnace structure that can improve the baking potential of the machine.

In order to solve the above problems, the present invention has the following configurations. It should be noted that the constituent elements described below can be employed in any possible combination. In addition, the aspects and technical features of the present invention are not limited to those described below, but are described in the entire specification and drawings, or are based on inventive ideas that can be understood by those skilled in the art from these descriptions. It should be understood that it is recognized on the basis of

The Baumkuchen baking machine of the present invention comprises a baking furnace equipped with a heat source, a pair of left and right rotating drums facing each other and rotatably supported by a rotating drum shaft, a core rod, and a hollow shaft for receiving the core rod. A rod-shaped body attached to a rod is provided, and one or a plurality of hanging rods are horizontally spanned between the rotating drums. From the first revolution intermittent stop position provided near the lower side of the inside, through the second revolution intermittent stop position provided near the upper side in the opening of the firing furnace, and further through a plurality of subsequent revolution intermittent stop positions a driving mechanism for controlling a revolution motion for sequentially revolving and moving to the first revolution intermittent stop position and a rotation motion for rotating the rod while being supported by the rotating drum; A dough tray installed so as to be movable up and down from below in order to apply the dough to the rod body at the revolution intermittent stop position, a dough baking zone of the baking furnace, and a dough coating zone on the opening side of the baking furnace. a first partition shutter and a second partition shutter which are advanced and retracted to block the orbital motion trajectory in synchronization with the intermittent orbital motion of the drive mechanism to separate the is provided between the first intermittent revolution stop position and the intermittent revolution stop position immediately before that, and the second partition shutter is provided between the first intermittent revolution stop position and the second intermittent revolution immediately after that. provided between stop positions, only the first intermittent revolution stop position is provided in the dough coating zone, and all the intermittent revolution stop positions other than the first intermittent revolution stop position are included in the dough baking zone. It is characterized by partitioning into

In a conventional Baumkuchen baking machine, the shielding position of the second partition shutter is to shield between the second revolution intermittent stop position and the revolution intermittent stop position immediately after that, so the first revolution intermittent stop position and the second revolution intermittent stop position becomes the dough coating zone, and the remaining revolution intermittent stop positions are included in the dough baking zone. Only the first revolution intermittent stop position becomes the dough application zone, all the revolution intermittent stop positions other than the first revolution intermittent stop position are included in the dough baking zone, and the baking space in the dough baking zone is conventionally ratio can be increased (eg, 30% increase), greatly improving the bakeability of the dough.

Here, the mechanism of the second partition shutter is preferably a folding extension mechanism or a sliding extension mechanism. If the mechanism of the second partition shutter is a push-out type, there is no room for installation on the inner back side of the furnace space or the front side of the open space. Become.

In the above configuration, the shielding direction of the second partition shutter is from the inner depth side of the baking furnace to the upper edge of the opening of the baking furnace, and when the second partition shutter is shielding the dough baking zone and the opening. is preferably shielded.
With the above configuration, the dough baking zone and the opening can be separated by shielding, and the opening can be made slightly smaller, so that the worker can be prevented from being exposed to the exhaust heat of the baking furnace that is received from the opening, and the work space can be reduced. environment can be improved.

Next, it is possible to devise ways to secure time for the molding operation in the Baumkuchen baking machine of the present invention. In the above configuration, the synchronization timing between the revolving motion of the rod body by the drive mechanism and the shielding movement of the first partition shutter and the second partition shutter is adjusted, and the revolution of the rod body is adjusted. As a result of the movement, after each of the rod bodies stops at the revolution intermittent stop position, the first partition shutter and the second partition shutter can be synchronized to start the shielding movement after a predetermined time delay. can.

Here, it is also possible to perform control so that the start of the shielding movement of the second partition shutter is delayed by a predetermined time from the start of the shielding movement of the first partition shutter.
With the above structure, after the dough is applied to the Baumkuchen being formed around the vertical rod by the dough tray at the first revolution intermittent stop position, the spatula is used to apply the dough evenly and in a good shape. However, in the Baumkuchen baking machine of the present invention, the second revolution intermittent stop position to be stopped next is already shielded by the second partition shutter and divided into dough baking zones. However, even an inexperienced worker or a veteran worker may not be able to complete the molding operation due to a slight deviation in timing. Therefore, instead of shielding with the second partition shutter immediately after reaching the second revolution intermittent stop position in the revolution movement and temporarily stopping, it is possible to adjust so that the shielding movement is performed after a predetermined time delay, and the molding time is sufficiently long. can be secured.

It is also preferable to provide a shutter opening/closing control means capable of adjusting the delay timing of the predetermined time of the start of the shielding movement of the second partition shutter with respect to the start of the shielding movement of the first partition shutter.
With the above configuration, it is possible to make adjustments in consideration of the worker's skill level, fatigue due to an excessive amount of work, and the like.
For example, if the shutter opening/closing control means has a button or a footswitch, and the button or footswitch is pressed to start the shielding movement of the second partition shutter, the operator himself/herself completes the molding operation. The timing of the shielding movement of the second partition shutter can be actively adjusted using a foot switch or the like.

Next, in the above configuration, it is possible to provide, near the upper surface of the firing furnace, a top surface heat source whose heat conduction area is widened with respect to the second revolution intermittent stop position provided near the upper side of the opening of the firing furnace. preferable.
In the conventional Baumkuchen baking machine, since the dough application zone extends up to the second intermittent revolution stop position, it is necessary to prevent heat conduction for heating to the second intermittent revolution stop position. However, in the Baumkuchen baking machine of the present invention, since the second revolution intermittent stop position is the dough baking zone, the upper surface heat source whose heat conduction area is expanded positively with respect to the second revolution intermittent stop position is positively used. By providing it, the firing ability (sintering potential) can be improved.
In addition, at the second intermittent revolution stop position, it is possible that an operator may perform molding work in the initial stage of stopping, so it is also preferable to separate the stage of molding work from the subsequent firing stage. Therefore, when the second partition shutter is closed, the heating of the upper surface heat source is set to a predetermined heating amount, and when the second partition shutter is opened, the heating of the upper surface heat source is temporarily stopped or weakened. It shall be provided with a heating adjustment control means for adjusting the temperature.

Next, the shortening of the baking time in the Baumkuchen baking machine of the present invention will be described.
Since the Baumkuchen baking machine of the present invention has an enlarged baking space and improved baking capacity as described above, it is possible to shorten the time required for imparting baking calories required for one cycle of conventional revolution motion. Therefore, in the conventional Baumkuchen baking, the speed of the revolution motion by the drive mechanism is blocked between the second partition shutter blocking position and the intermittent revolution stop position immediately after the second intermittent revolution stop position. It is possible to operate at a higher speed than the speed of the orbital motion in the machine.

According to the Baumkuchen baking machine of the present invention, the baking space is expanded so that the whole area other than the first revolution intermittent stop position is the dough baking zone, the baking process can be improved, and moist and soft Baumkuchen can be baked in a short time. can. Furthermore, it is possible to add an additional heat source on the upper surface of the furnace where the heat conduction area extends to the second revolution intermittent stop position, thereby improving the baking capacity (firing potential) of the Baumkuchen baking machine and shortening the Baumkuchen baking time. .
In addition, according to the Baumkuchen baking machine of the present invention, the upper edge of the opening can be shielded immediately after the operator's molding work, the opening itself can be made slightly smaller, and the baking environment for the operator during the baking work can be improved.

Hereinafter, embodiments of the Baumkuchen baking machine of the present invention and the hanging rod used in the Baumkuchen baking machine of the present invention will be described with reference to the drawings. However, it goes without saying that the scope of the present invention is not limited to those shown in the following examples.

As Example 1, a configuration example of the Baumkuchen baking machine 100 of the present invention will be described.
FIG. 1 is a diagram very simply showing the basic structure of a Baumkuchen baking machine 100 of the present invention. Although FIG. 1(a) is a front view, it is illustrated in cross section so that the internal components can be easily understood. FIG. 1(b) is a left side view, showing a cross section for easy understanding of internal components. Both are simply illustrated so that the internal structure and the intermittent revolution stop position can be understood.

The configuration example of the Baumkuchen baking machine 100 of the present invention, as shown in FIG. A first partition shutter 160 , a second partition shutter 170 and an inner back partition plate 180 are provided. These are examples of the basic structure, and the mechanisms and functions of these components may be improved and different, and the Baumkuchen baking machine 100 to which other components different from these components are added Also good.
1, the core rod 210 of the support rod body 200 can be supported at the position of the support rod of the rotary drum 130, and the support rods are assumed to be provided at the revolution intermittent stop positions of the rotation drum 130. do.

The housing 101 is made of a highly heat-resistant metallic material.
The operation control panel 102 controls the operation of the Baumkuchen baking machine 100, and is arranged, for example, on the front surface of the apparatus, but the arrangement location is not limited. Switches, buttons, a touch panel, and the like for inputting operation instructions are arranged, and a foot switch and the like may be provided.
An opening 103 is an opening opened in the housing 101 . A dough tray 150 is positioned below and serves as an access point for workers to approach the dough application zone. The inside of the opening 103 is partitioned by a first partition shutter 160, a second partition shutter 170, and an inner/back partition plate 180, which will be described later, and the first partition shutter 160 and the second partition shutter 170 are in a closed state. If there is, it is separated from the space of the dough baking zone.

The firing furnace 110 is made of a metal or ceramic material having excellent heat resistance, and has a heat source 120 inside. Even a baking furnace provided with a normal Baumkuchen baking machine can be used because the set temperature and the like are within the allowable range.
Although the size of the firing furnace 110 is not limited, it is housed in a case of, for example, width 1500 mm×height 1650 mm×depth about 1000 mm.
An opening 111 is provided in front of the firing furnace 110 . A worker stands in front of this opening 111 to perform the work.

The rotating drums 130 are a pair of right and left facing drums, are rotatably supported by a rotating drum shaft, and are driven by a driving mechanism 140 to perform intermittent rotational motion. Although the material of the rotating drum 130 is not particularly limited, for example, stainless steel with high heat resistance may be used.
A rod body 200 is inserted and horizontally mounted on a rod portion of the rotating drum 130 in a freely removable and replaceable manner. , and in this configuration example, six hanging rod bodies 200 are arranged. Of course, the number and thickness of the rod bodies 200 are not limited, and the length of the rod bodies 200 is determined by the distance between the rotating drums 130 .

In this configuration example, six positions are intermittently provided in the orbital motion of the rotary drum 130, and the rotary drum shaft 131 rotates intermittently to divide the firing process into six stages. . In other words, it makes one round by intermittently moving six times.
Here, the six revolution intermittent stop positions are defined as a first revolution intermittent stop position (1), a second revolution intermittent stop position (2), a third revolution intermittent stop position (3), and a fourth revolution stop position (3). Intermittent stop position (4), fifth intermittent revolution stop position (5), and sixth intermittent revolution stop position (6). In the figure, they are simply numbered from (1) to (6).
In the baking process of the Baumkuchen baking machine 100, the baking process executed at each of these revolution intermittent stop positions is as follows.

The baking process at the first revolution intermittent stop position (1) is the dough application process+dough molding process. Once the dough application is complete and the dough tray is lifted, the dough molding process can continue. A dough tray 150 is installed below the first revolution intermittent stop position ( 1 ), and has an elevating mechanism for elevating the dough tray 150 in synchronization with the revolution of the rotary drum 130 . A detailed operation will be described later.

The firing process at the second revolution intermittent stop position (2) is a steaming molding process+steaming firing process. As will be described later, the second partition shutter 170 is shielded during one intermittent revolution stop period stopped at the second intermittent revolution stop position (2). As will be described later, it is also possible to carry out two processes, a steaming molding process and a steaming baking process, before and after the second partition shutter 170 shields at the second revolution intermittent stop position (2). Details will be described later.

The firing process at the third revolution intermittent stop position (3) is the first main firing process.
The firing process at the fourth revolution intermittent stop position (4) is the second main firing process.
The firing process at the fifth revolution intermittent stop position (5) is a coloring firing process.
The firing process at the sixth revolution intermittent stop position (6) is a trimming and preparation process. Since this trimming preparation process itself is also in the dough baking zone, the baking continues.

Thus, there is a baking process at six intermittent revolution stop positions, but only the first intermittent revolution stop position (1) is the unbaked "dough coating zone" and the second intermittent revolution stop position (2 ) to the sixth revolution intermittent stop position (6) are in the “dough baking zone”. Thus, the Baumkuchen baking machine 100 of the present invention has only one revolution intermittent stop position in the "dough coating zone" compared to the conventional one, and conversely, in the "dough baking zone" A major feature is that the number of revolution intermittent stop positions is increased by one.

The heat source 120 is a heat supply source arranged in the baking furnace 110, but is not particularly limited as long as it can supply sufficient calories for baking Baumkuchen. For example, gas combustion equipment and electric heating equipment are suitable as a stable heat source that prevents uneven baking.
In this configuration example, four heat sources 120, namely, a gas burner 121, an electric heating device 122, an electric heating device 123, and an electric heating device 124 as an additional heat source are provided in the firing furnace 110. .
A gas combustor 121 is provided at the innermost part of the combustion furnace 110 at an angle toward the center of the combustion furnace 110, and widely supplies heat to the entire dough baking zone of the combustion furnace 110. , the revolution intermittent stop position (5) and the fourth revolution intermittent stop position (4).
The electric heater 122 is provided so as to face the support rod supported at the fifth intermittent revolution stop position (5) in the combustion furnace 110 .
The electric heater 123 is provided at an angle so as to face the support rod supported at the fourth revolution intermittent stop position (4) in the combustion furnace 110 .
Furthermore, an electric heating device 124 as an additional heat source is provided near the upper surface (ceiling bank) inside the combustion furnace 110 . The electric heating device 124, which is the additional heat source, is arranged near the third revolution intermittent stop position (3) as a heat source, and furthermore, the second revolution intermittent stop position (2) is also provided with the heat. The conduction range is widened.

In the Baumkuchen baking machine 100 of the present invention, the second revolution intermittent stop position (2), which was conventionally treated as being in the "dough coating zone", is replaced by the second partition shutter described later in the Baumkuchen baking machine 100 of the present invention. Because it is located in the "dough baking zone" due to the shielding of , the structure is such that the heating of the baking furnace 110 is sufficiently distributed, and the electric heating device 124, which is the additional heat source, is located at the second revolution intermittent stop position (2). Since the heat conduction area is expanded relatively close to each other, the heat conduction is such that the Baumkuchen dough of the hanging rod body 200 at the second revolution intermittent stop position (2) can be sufficiently baked. The feature is that is ensured.

The drive mechanism 140 is a drive mechanism that brakes so as to rotate around the shaft on which the rod body 200 is supported and to revolve around the rotary drum shaft 131 by intermittent rotation of the rotary drum 130 . . In this configuration example, since there are six suspension rods 200 and they are suspended at six positions on the rotary drum 130, the revolution is an example of rotating 60 degrees for each stroke.
As will be described later, the Baumkuchen baking machine 100 of the present invention expands the "dough baking zone" by shielding with the second partition shutter 170 in the baking process provided by the intermittent revolution movement in one cycle. By increasing the revolution intermittent stop position in the "zone" and increasing the amount of heat supplied to Baumkuchen by the electric heating device 124, which is an additional heat source, the dough can be baked in one cycle even if the intermittent revolution motion time of one cycle is shortened. It is possible. Therefore, the drive mechanism 140 can increase the speed of the intermittent revolution motion. That is, the firing time for one cycle is shortened.

The dough tray 150 is arranged directly below the first revolution intermittent stop position (1), and has an elevating mechanism that moves up and down in synchronization with the revolution motion of the rotary drum 130 . The dough tray 150 is lowered so as not to interfere with the revolution motion when the suspension rod 200 is making a revolving motion. 200 will be immersed in the fabric to a given depth. The lifting operation of the dough tray 150 will be described later.

Next, the first partition shutter 160 and the second partition shutter 170 are described.
The first partition shutter 160 and the second partition shutter 170 are partition shutters for separating the “dough baking zone” of the baking furnace 110 from the “dough application zone” on the opening 111 side of the baking furnace 110 . The shielding performance is improved by facing the inner/back partition plate 180 .
The first partition shutter 160 is provided in the interior of the firing furnace 110, and in this configuration example, between the first revolution intermittent stop position (1) and the immediately preceding sixth revolution intermittent stop position (6). is provided in a position to shield the
The second partition shutter 170 is provided near the upper edge of the opening 111 of the kiln 110. In this configuration example, the first revolution intermittent stop position (1) and the second revolution intermittent stop position (2 ) is provided at a position to shield between

The shielding movements of the first partition shutter 160 and the second partition shutter 170 are synchronized with the intermittent revolution motion of the drive mechanism 140 and are operated to block the intermittent revolution motion trajectory of the rod body 200 . In other words, during the intermittent revolving movement of the rod body 200, the first partition shutter 160 and the second partition shutter 170 return to their standby positions so as not to interfere with the passage of the rod body 200, respectively. When the intermittent revolution motion of the rod body 200 is finished and the rod body 200 is temporarily stopped at each revolution intermittent stop position, the first partition shutter 160 and the second partition shutter 170 are extended together, and the first partition shutter is opened. 160 shields between the first intermittent revolution stop position (1) and the immediately preceding sixth intermittent revolution stop position (6), and the second partition shutter 170 separates the first intermittent revolution stop position (1) and It moves so as to shield between the second revolution intermittent stop positions (2) immediately after.

Due to the shielding movement of the first partition shutter 160 and the second partition shutter 170, only the rod body 200 at the first revolution intermittent stop position (1) is partitioned as a "dough application zone", and the first All of the five rods 200 located at the second intermittent revolution stop position (2) to the sixth intermittent revolution stop position (6) other than the intermittent revolution stop position (1) are used as a "dough baking zone" in the baking furnace 110. trapped inside. Each rod body 200 confined in the “dough baking zone” in this way is effectively subjected to the baking process in the baking furnace 110 .

Here, the first partition shutter 160 may be a mechanism for lifting and lowering a metal plate because the housing of the Baumkuchen baking machine 100 has room and the space below the baking furnace 110 can be easily utilized. However, since the second partition shutter 170 advances and retreats in the horizontal direction so as to shield the vicinity of the upper edge of the opening 111, there is little space for horizontal movement of the second partition shutter 170 as a mere metal plate. often.
Therefore, the inventors of the present invention have realized that the shielding mechanism of the second partition shutter 170 can be configured to be a folding extension mechanism or a sliding extension mechanism. FIG. 2 is a diagram simply illustrating the shielding mechanism of the second partition shutter 170. As shown in FIG. The upper diagram in FIG. 2 shows how the second partition shutter 170 adopting the folding and retracting mechanism moves for blocking, and the lower diagram in FIG. In either case, the second partition shutter 170 can be moved to block by utilizing the space of the revolving motion in the kiln 110 . If it is a single-plate flap type, the space required for flap movement due to shielding becomes large, and there is a risk of colliding with the hanging rod body 200. With the adopted configuration, the space required for shielding movement may be small.

The shielding direction of the second partition shutter 170 is set to the direction of moving from the inner depth side of the baking furnace 110 to the upper edge of the opening 111 of the baking furnace 110, and when the second partition shutter 170 is shielded, the "dough baking zone". and the "dough application zone" on the opening 111 side can be clearly shielded. In this way, by moving the second partition shutter 170 to cover, it is possible to keep the opening 111 as small as possible while ensuring the width of the opening 111 for workers to work. The larger the opening 111, the easier it is for the worker to perform the dough molding work. Furthermore, the space of the "dough baking zone" in the baking furnace 110 becomes smaller, which is a disadvantage for the baking process. With the above configuration, the opening 111 can be kept relatively small while securing the space for the worker's dough molding work, and the environment for the worker working facing the opening 111 can be improved. , a large space for the “dough baking zone” in the baking furnace 110 can be secured.

Next, one cycle baking process of the Baumkuchen baking machine 100 of the present invention according to the first embodiment will be described.
3 to 10 are diagrams for briefly explaining the revolving motion of the suspension rod 200 supported on the rotating drum 130 by the braking of the drive mechanism 140. FIG. These figures simply illustrate the horizontal position of the suspension rod 200 with respect to the rotating drum 130 . That is, the rod bodies 200A to 100F are drawn so that the cross section of the core rod 10 of the rod body can be seen.
The front side of the Baumkuchen baking machine 100 is on the right side.
The following description focuses on one rod body 200A. The suspension rod is painted black in the drawing. 3 and 4 show the operation in the first interval of the orbital motion, FIG. 5 shows the operation in the second interval of the orbital motion, and FIG. 6 shows the increase in the space of the dough baking zone. FIG. 7 is a diagram showing the operation in the third interval of the revolution motion, FIG. 8 is a diagram showing the operation in the fourth interval of the revolution motion, and FIG. 10 is a diagram showing the operation in interval No. 5, and FIG. 10 is a diagram showing the operation in the sixth interval of revolutional motion.

[First revolution intermittent stop position (1): fabric application process + fabric molding process]
Assume that the previous cycle has ended and the rod body 200A has arrived at the first revolution intermittent stop position (1) as shown in FIG. 3(a). Here, the dough tray 150 is lowered by the elevating mechanism until the support bar 200A stops at the first revolution intermittent stop position (1).
Next, when the rod body 200A stops at the first revolution intermittent stop position (1) and the dough coating process, which is the first process of the baking process, starts, the first The second partition shutter 160 and the second partition shutter 170 are moved to shield and partition the dough baking zone and the dough application zone. Also, the dough tray 150 is lifted by the elevating mechanism of the dough tray 150 . Dough is accumulated to a predetermined depth in the dough tray 150, and the hanging bar 200 is immersed in the dough in the dough tray 150 to a predetermined depth. Since the suspension rod 200A rotates, the dough in the dough tray 150 is applied to the entire surface of the suspension rod 200A.
If the interval time of the revolution intermittent motion is long, the hanging bar 200A is excessively immersed in the dough. may be terminated.
Here, in the middle of the first cycle of the revolution motion, the dough tray 150 descends after a predetermined period of time has passed, and the hanging bar 200A comes out of the dough tray 150, as shown in FIG. 4(a). As shown in FIG. 4(b), the worker can begin to perform a dough shaping process to smooth the surface of the dough attached to the hanging rod 200A. In the dough molding process, the spatula 210 or the like is brought into contact with the surface of the baked Baumkuchen to remove irregularities on the surface of the dough and lumps in the dough. During this time, the first partition shutter 160 and the second partition shutter 170 remain shielded, the dough baking zone and the dough coating zone are separated, and the workers are not directly exposed to the exhaust heat of the baking furnace 110. The working environment is maintained in good condition.

[Second Revolution Intermittent Stop Position (2): Steaming Molding Process + Steaming Firing Process]
When the next revolution movement of the rotary drum 130 starts, the first partition shutter 160 and the second partition shutter 170 are moved to release the shielding state, and the rod body 200 is moved, as shown in FIG. 5(a). The positions of the first shutter 160 and the second shutter 170 are passable. The rod body 200A at the first intermittent revolution stop position (1) moves to the second intermittent revolution stop position (2). When the rod body 200A reaches the second revolution intermittent stop position (2), the rotation of the rotary drum 130 is temporarily stopped again.
The second interval of this revolution motion is the baking process at the second revolution intermittent stop position (2), which is "steaming molding process"+"steaming baking process".
As shown in FIG. 5( a ), even if the rod body 200 A reaches the second revolution intermittent stop position ( 2 ), if it is before the second partition shutter 170 shields, the operator can move the rod. The dough molding process for body 200A can also be continued. A skilled and fast worker can fully complete the dough forming process during the first revolution intermittent stop position (1), but an unskilled worker and a dough clump remover will be able to fully complete the dough forming process. Even if the dough molding process cannot be completed between the first revolution intermittent stop positions (1) due to a delay, etc., even if the second revolution intermittent stop position (2) is reached, this second Before the second partition shutter 170 is blocked, the rod 200A is in a position accessible to the operator, so that the dough forming process can be continued. Here, the molding process at the second revolution intermittent stop position (2) is called a "steaming molding process".

Next, as shown in FIG. 5B, the first partition shutter 160 and the second partition shutter 170 block at a predetermined timing. In addition, in this Example 1, as shown in FIG. 5(b), the first partition shutter 160 and the second partition shutter 170 are operated at the same time for shielding.
As will be described later, in the second embodiment, there is a control example in which the shielding timing of the second partition shutter 170 is shifted from the shielding of the first partition shutter 160, and an operator sets the shielding timing of the second partition shutter 170. Give an example of what you can control. They will be collectively described as Example 2 below.
In Example 1, as shown in FIG. 5B, the first partition shutter 160 and the second partition shutter 170 are shielded to separate the "dough application zone" and the "dough baking zone". In the embodiment, the second partition shutter 170 shields between the first intermittent revolution stop position (1) and the second intermittent revolution stop position (2). When the "dough baking zone" is divided, the second revolution intermittent stop position (2) is located in the "dough baking zone".

Thus, when the second partition shutter 170 is blocked, the "steaming baking process", which is part of the baking process, starts at the second revolution intermittent stop position (2). As shown in FIG. 5, the electric heating device 124, which is the additional heat source, is located relatively close to the second revolution intermittent stop position (2), and the heat conduction area is widened. Heat conduction is ensured so that the Baumkuchen dough on the rod body 200 at the revolution intermittent stop position (2) can also be sufficiently baked.
In the case of a conventional Baumkuchen baking machine, even if there is something equivalent to a partition shutter, it is located at the second revolution intermittent stop position (2) and the third revolution intermittent stop position (3). Even if the partition shutter 170 is blocked, the second revolution intermittent stop position (2) is located in the "dough application zone" and the baking process does not start. Since the revolution intermittent stop position (2) of is located in the "dough baking zone", the "steaming baking process" which is a part of the baking process starts at the second revolution intermittent stop position (2).

In this way, by devising the blocking position of the second shutter 170, as shown in FIG. It is understood that For example, the "dough baking zone" is expanded by about 30% compared to the conventional one.
In addition, since the "steaming baking process" which is a part of the baking process starts at the second revolution intermittent stop position (2), in one round cycle of the rotating drum 130 due to the revolution motion, the hanging rod 200 "bakes the dough". The time to pass through the "zone" is longer, and the ratio of the firing time to the total revolution time is greatly improved compared to the conventional method.

[Third Revolution Intermittent Stop Position (3): First Main Firing Process]
When the next revolution movement of the rotary drum 130 starts, as shown in FIG. 7A, the first partition shutter 160 and the second partition shutter 170 are moved to release the shielding state, and the rod body 200A is The position of the second shutter 170 can be passed. When the rod body 200A at the second intermittent revolution stop position (2) moves to the third intermittent revolution stop position (3) and reaches the third intermittent revolution stop position (3), the rotation of the rotary drum 130 is temporarily stopped again.
The firing process at the third revolution intermittent stop position (3) is the first main firing process. During the period of stopping at the third intermittent revolution stop position (3), in this configuration example, as shown in FIG. 3), and the first main firing process is performed on the rod body 200A.

[Fourth Revolution Intermittent Stop Position (4): Second Final Firing Process]
When the next revolution movement of the rotary drum 130 starts, the first partition shutter 160 and the second partition shutter 170 move to release the shielding state, and the rod body 200 moves, as shown in FIG. 8(a). The positions of the first shutter 160 and the second shutter 170 are passable. When the rod body 200A at the third revolution intermittent stop position (3) moves to the fourth revolution intermittent stop position (4) and reaches the revolution intermittent stop position (4), the rotation of the rotary drum 130 is temporarily stopped again.
The firing process at the fourth revolution intermittent stop position (4) is the second main firing process. During the period of stopping at the fourth revolution intermittent stop position (4), in this configuration example, as shown in FIG. It is provided at an angle so as to face the suspended rod body, and is relatively close to the gas combustor 121, and the second main firing process for the rod body 200A is performed.

[Fifth revolution intermittent stop position (5): coloring firing process]
When the next revolution movement of the rotary drum 130 starts, as shown in FIG. The positions of the first shutter 160 and the second shutter 170 are passable. When the rod body 200A at the fourth revolution intermittent stop position (4) moves to the fifth revolution intermittent stop position (5) and reaches the revolution intermittent stop position (5), the rotation of the rotary drum 130 is temporarily stopped again.
The firing process at the fifth revolution intermittent stop position (5) is a coloring firing process. During the period of stopping at the fifth intermittent revolution stop position (5), in this configuration example, as shown in FIG. It is provided so as to face the rod body suspended at the stop position (5), and the coloring firing process is performed on the rod body 200A. The coloring baking process does not change as a baking process, and is called the coloring baking process because the baked Baumkuchen dough progresses and the surface begins to be browned.

[Sixth Revolution Intermittent Stop Position (6): Preparation Process]
When the next revolution movement of the rotary drum 130 starts, the first partition shutter 160 and the second partition shutter 170 are moved to release the shielding state, and the rod body 200 is moved, as shown in FIG. 10(a). The positions of the first shutter 160 and the second shutter 170 are passable. When the rod body 200A at the fifth intermittent revolution stop position (5) moves to the sixth intermittent revolution stop position (6) and reaches the intermittent revolution stop position (6), the rotation of the rotary drum 130 is temporarily stopped again.
The baking process at the sixth revolution intermittent stop position (6) is a coloring baking process. During the period of stopping at the sixth intermittent revolution stop position (6), in this configuration example, the gas combustor 121 is supported at the sixth intermittent revolution stop position (6) as shown in FIG. It is also close to the hanging rods that have been installed, and the trimming and preparation process for the hanging rods 200A proceeds. It should be noted that the preparation process does not change as a baking process, and the baking of the Baumkuchen dough is progressing.

[Circulation to the first revolution intermittent stop position (1)]
Returning from FIG. 10 to FIG. 3, the rod body 200A at the sixth intermittent revolution stop position (6) moves to the first intermittent revolution stop position (1) and circulates.
In this manner, the rod body 200A revolves around the firing furnace 110 as the rotating drum 130 revolves. 15 to 30 cycles are repeated with the flow from FIG. 3 to FIG. 9 as one cycle, and the Baumkuchen is baked around the rod 200A.

Here, the revolution speed in the Baumkuchen baking machine 100 of the present invention will be described.
The revolution speed referred to here is the intermittent revolution motion of the Baumkuchen baking machine 100 of the present invention. irpm: intermittent rotation per minute). The unit of rpm is often used to express the speed of a non-stop revolution, but since it revolves intermittently, it is indicated as an intermittent revolution speed.
In the Baumkuchen baking machine 100 of the present invention, as described above, the "steaming baking process", which is a part of the baking process, starts at the second revolution intermittent stop position (2). cycle, the ratio of the firing time to the total revolution time is greatly improved. In addition, the addition of the electric heating device 124, which is an additional heat source, increases the amount of heat in the combustion furnace 110, which increases the firing efficiency and shortens the time required for firing. can be greatly improved than the conventional Baumkuchen baking machine.
According to the Baumkuchen baking machine 100 of the present invention, it was found that the Baumkuchen can be sufficiently baked even if the intermittent revolution speed is increased compared to the conventional one due to the improvement of the baking efficiency. As an example, the intermittent rotation speed of conventional models in the industry is about 1.5 (irpm), that is, the drum rotates 1.5 times per minute. Baumkuchen was baked at an intermittent rotation speed of 3.3 (irpm), that is, at a speed at which the drum rotated 3.3 times per minute. In other words, it was found that Baumkuchen can be baked by intermittently rotating at 2.2 times the speed.
After repeated experiments, it was found that Baumkuchen can be baked at an intermittent rotation speed of about 2 to 3 times that of conventional models in the industry. In terms of Baumkuchen baking time, we were able to reduce the time to about 1/2 to 1/3 compared to conventional models in the industry. The baked Baumkuchen was equivalent to Baumkuchen baked by a conventional Baumkuchen baking machine. In other words, according to the Baumkuchen baking machine 100 of the present invention, it was confirmed that the Baumkuchen baking time can be shortened by about 50% to 65% compared to the conventional machine.

As Example 2, a Baumkuchen baking machine 100a incorporating a device regarding the timing of the shielding movement of the second partition shutter 170 will be described.
FIG. 11 is a diagram simply showing the basic structure of the Baumkuchen baking machine 100a according to the second embodiment. It is simply illustrated from the left side direction, and is simply illustrated so that the internal structure and the revolution intermittent stop position can be understood.
As shown in FIG. 11, the configuration example of the Baumkuchen baking machine 100a of the present invention according to the second embodiment includes a baking furnace 110, a heat source 120, a rotating drum 130, a drive mechanism 140, a dough tray 150, a first partition shutter 160, A second partition shutter 170 , an inner/back partition plate 180 , and shutter opening/closing control means 190 are provided. These are examples of the basic structure, and even if the mechanisms and functions of these components are improved and different, or the Baumkuchen baking machine 100a with other components different from these components added good. The shutter opening/closing control means 190 may be installed anywhere as long as it can communicate with the first partition shutter 160 and the second partition shutter 170, and is simply illustrated in FIG. 11 for convenience.
The apparatus configuration itself of the Baumkuchen baking machine 100a according to the second embodiment is the same as the apparatus configuration of the first embodiment. 160 and the part related to the opening/closing control of the second partition shutter 170 will be mainly described.

The shutter opening/closing control means 190 is a part that controls the opening/closing of the first partition shutter 160 and the second partition shutter 170 . Under the control of the shutter opening/closing control means 190 , the shielding movement of the first partition shutter 160 and the shielding movement of the second partition shutter 170 are operated in synchronization with the orbital movement of the rod body 200 by the drive mechanism 140 .
The first partition shutter 160 and the second partition shutter 170, which separate the dough application zone and the dough baking zone, operate in synchronization with the orbital movement of the rod body 200 by the drive mechanism 140 as follows. do.

As described in Embodiment 1, the shutter opening/closing control means 190 controls the first partition shutter 160 and The second partition shutter 170 is also controlled to be open.
Subsequently, at the end of the orbital motion, as a result of the orbital motion of the rod bodies 200, each of the rod bodies 200 passes through the first partition shutter 160 and the second partition shutter 170 and stops at the revolution intermittent stop position. , the shielding movement of the first partition shutter and the second partition shutter starts with a delay of a predetermined time.

Based on this movement, in the Baumkuchen baking machine 100a of the present invention of the second embodiment, the shutter opening/closing control means 190 can be devised as follows.
A first idea is to delay the start of the shielding movement of the second partition shutter 170 by a predetermined time from the start of the shielding movement of the first partition shutter 160 .
FIG. 12 is a diagram showing a device for delaying the start of the blocking movement of the second partition shutter 170 by the shutter opening/closing control means 190 according to the second embodiment by a predetermined time.
The first partition shutter 160 is located at the innermost part of the firing furnace 110, and immediately shuts off the heat of the firing furnace 110 so that the heat of the firing furnace 110 does not escape as soon as the orbital movement of the rod body 200 by the drive mechanism 140 is completed. good. Therefore, as shown in FIG. 12(a), the shutter opening/closing control means 190 causes the first partition shutter 160 to start shielding movement as soon as the orbital movement of the rod body 200 by the drive mechanism 140 is completed. .

The second partition shutter 170 is located on the front side of the baking furnace 110 and shields the second revolution intermittent stop position (2) to the dough baking zone side. Delaying the movement of the shield for a predetermined period of time may contribute to the worker's work. For example, when the dough forming work at the first revolution intermittent stop position (1) is not sufficiently completed, such as when an unskilled worker takes time in the dough forming work, or when fatigued from continuous work, the It may be convenient if there is enough time to continue the dough molding operation for a predetermined time even after reaching the revolution intermittent stop position (2) of 2. Therefore, the shutter opening/closing control means 190 makes it possible to adjust the delay timing of the start of the shielding movement of the second partition shutter 170 by a predetermined time, and as shown in FIG. is delayed.
In addition, it is preferable that the operator can set and input the delay of the predetermined time for the start of the shielding movement of the second partition shutter 170 . Alternatively, the shutter opening/closing control means 190 may be provided with a button or a footswitch, and pressing the button or the footswitch may start the blocking movement of the second partition shutter.

Next, it is possible to contrive to interlock the shielding movement of the second partition shutter 170 with the intensity of a part of the heat source in the combustion furnace 110 . The heat source for interlocking the intensity is not limited, but a heat source close to the second revolution intermittent stop position (2), such as the electric heating device 124 as an additional heat source, is preferable.
Interlocking the shielding movement of the second partition shutter 170 with the intensity of the heat source in the combustion furnace 110 improves the working relationship of the operator. That is, when the second partition shutter 170 is in the open state, the exhaust heat in the combustion furnace 110 is emitted from the front opening of the Baumkuchen baking machine 110a, and the worker is exposed to the exhaust heat. Dimming or suspending some of the heat sources within the furnace 110 when 170 is open improves the working environment for the operator. In order not to excessively lower the temperature in the combustion furnace 110, the intensity of the heat source near the second revolution intermittent stop position (2) may be weakened, and the other heat sources may not be weakened.

While the preferred embodiment of the Baumkuchen baking machine 100 of the present invention has been illustrated and described, it will be appreciated that various modifications can be made without departing from the scope of the invention.

The Baumkuchen baking machine 100 of the present invention can be widely applied as equipment and members for producing new baked goods.
