[0004]
The rotating shaft 5 is formed with a fluid supply path 7 in the axial direction. The agitating blade 6 communicates with the fluid supplying path 7 and opens in a direction opposite to the rotating direction of the agitating blade 6. A blowout hole 8 is provided. Further, a steam supply means 9 and a purified air supply means 10 are connected to the rotary shaft 5, respectively, and steam and purified air are selectively supplied to the fluid supply path 7 of the rotary shaft 5 via the electromagnetic on-off valves 11 and 12. It is configured to be supplied.
[0005]
In the steaming machine 1 having the above-described configuration, first, after adding materials such as water and powder and additives such as sugar into the steaming chamber 2, the drive source is started and the stirring blade 6 is moved via the rotating shaft 5. Rotate to mix the materials for a predetermined time.
[0006]
Next, in order to steam the dough, the electromagnetic on-off valve 12 of the purified air supply means 10 is closed, and then the steam generated by the boiler of the steam supply means 9 is supplied to the fluid supply path 7 of the rotary shaft 5. Supply in. The supplied steam blows the steam on the whole of the mixed material from a large number of fluid blowing holes 8 in the direction opposite to the rotation direction while the stirring blade 6 rotates.
As a result, it is possible to steam a uniform dough with a small amount of steam in a short time.
[0007]
On the other hand, when the dough has been steamed, the electromagnetic on-off valve 11 is closed, the electromagnetic on-off valve 12 is opened, and the purified air supply means 10 supplies fluid to the electromagnetic on-off valve 12 and the rotary shaft 5.

[0008]
[Problems to be solved by the invention]
However, the conventional steaming machine as described above has the following problems.
The rotating shaft 5 is supported by a pair of bearings 13 and 13, and rotational driving of a driving source is transmitted via the sprocket 14.
However, since the high temperature steam is supplied to the fluid supply path 7 of the rotating shaft 5, the bearings and the like constituting the bearings 13, 13 are heated by the heat transmitted to the bearings 13, 13 through the rotating shaft 5 and are normal. The rotating shaft 5 may not rotate smoothly.
[0009]
In order to replace the bearings 13 and 13, it is necessary to remove various pipes connected to the rotating shaft 5, or to remove the rotating shaft 5 itself from the steaming container 4. However, since the steaming operation has to be stopped, there is a problem that a great amount of time is lost.
[0010]
The present invention has been made in consideration of the above points, and suppresses the transfer of steam heat through the rotating shaft, so that the functional member mounted on the rotating shaft is damaged by heat. It aims at providing the steamer which can be suppressed.
[0011]
[Means for Solving the Problems]
  In order to achieve the above object, the present invention employs the following configuration.
  The steaming machine according to claim 1, a cylindrical stirring container having a steaming chamber inside,
  A cylindrical drive shaft rotatably mounted on the stirring vessel in a state where the tip side protrudes into the steaming chamber;
  In a steaming machine provided with a stirring blade provided on the tip side of the drive shaft and kneading the material charged into the steaming chamber,
  A steam supply pipe connected to a steam supply source and inserted through the drive shaft with a gap between the drive shaft;
  When the stirring blade rotates around the axis, the stirring blade is located on the rear side in the traveling direction of the stirring blade, guides the steam supplied through the steam supply pipe along the stirring blade, and moves backward in the traveling direction. A steam introduction pipe having a steam delivery hole drilled toward,
  The stirring blade is disposed so that the radius from the rotation axis is set to be approximately the same as the radius of the inner peripheral surface of the steaming chamber, and the spiral portion is made of a rectangular plate material, and is opposed to the spiral portion. And a crank portion that is arranged to be shifted outward while the central horizontal bar portion is maintained parallel to the rotation axis of the stirring blade.It is characterized by that.
[0012]
  Therefore, in the steaming machine of the present invention, by rotating the drive shaft, the stirring blades rotate to knead the material put into the steaming chamber. At this time, the steam supplied from the steam supply source is introduced from the steam supply pipe into the steam introduction pipe, and then sent out from the steam delivery hole toward the rear side in the traveling direction of the stirring blade. Thereby, since a vapor | steam can be sent out to the vicinity of the material kneaded, it can knead | mix uniformly throughout the dough. Moreover, since the steam delivery hole is arranged toward the rear side in the advancing direction of the stirring blade, clogging due to the dough can be prevented. Moreover, the steam introduction pipe can be easily manufactured because it can be retrofitted to the stirring blade by welding or the like. Furthermore, since a gap is formed between the drive shaft and the steam supply pipe, the amount of steam heat transmitted from the steam supply pipe to the drive shaft can be suppressed.
  Furthermore, in the steaming machine of the present invention, the material attached to the inner peripheral surface of the steaming chamber is transferred forward along the axial direction of the steaming chamber by rotating the stirring blade. At this time, when the front of the steaming chamber is closed, the material transferred forward is pushed back. Then, after the pushed-down material falls by its own weight to the central part or the rear part at the lower part of the steaming chamber, it is kneaded while being divided by the horizontal bar part of the crank part. Further, since the spiral portion is formed of a square plate material, the material is pushed by a surface instead of a line, so that the material transfer efficiency is improved as compared with the case of using a round bar or the like.
[0013]
A steamer according to a second aspect is the steamer according to the first aspect, further comprising an opening for opening a gap between the steam supply pipe and the drive shaft to the outside.
[0014]
Therefore, in the steamer of the present invention, air in the gap between the drive shaft and the steam supply pipe can be circulated to the outside, so that the temperature rise of the air can be suppressed.
Further, the drive shaft and the steam supply pipe can be cooled by the circulating air.
[0015]
The steaming machine according to claim 3 is a steaming machine according to claim 1 or 2, wherein the stirring blades are provided on the outside and the space for opening the steam supply pipe is provided on the inside. Is coaxially assembled to the front end side of the drive shaft, and the outer peripheral surface of the boss member has a protrusion protruding spirally around the axis of the drive shaft, and the boss member is rotated about the axis. A through hole penetrating into the space is provided on the rear side of the projecting portion in the traveling direction.
[0016]
Therefore, in the steaming machine of the present invention, the protruding portion rotates around the axis, so that the semi-kneaded dough that falls by its own weight from the stirring blade positioned above and adheres to the boss member is moved in the axial direction while kneading. be able to. At this time, the steam supplied through the steam supply pipe is ejected from the through hole, so that the steam can be sent to the vicinity of the kneaded material, and the entire dough can be uniformly steamed. Moreover, since this through-hole is arrange | positioned in the advancing direction back side of a protrusion part, it can prevent clogging with cloth | dough.
[0021]
  Claim 4The described steamer isClaims 1 to 3In the steamer according to any one of the above, the steam supply device including the steam supply source and the steam supply pipe, and the steam supply from a wall faced to the steaming chamber, which is disposed in a separate system from the steam supply device It is characterized in that a steam jetting device for jetting steam into the room can be selectively used.
[0022]
Therefore, in the steaming machine of the present invention, when the dough is given a firmness, only the steam supply device is used for steaming, and when making the dough soft, both the steam supply device and the steam jetting device are used. Depending on the dough to be steamed, it can be used arbitrarily. In addition, when both apparatuses are used, the steam hits the inner and outer surfaces of the dough, so that the steaming time can be shortened. Furthermore, since these devices are configured in separate systems, the steam pressure after branching becomes weak and the steam blow-out amount becomes unstable by supplying the steam in a branched manner as in the case of configuring in the same system. Can be prevented. Therefore, clogging at each steam blowing portion is less likely to occur, and the quality of the product after steaming can be maintained.

[0039]
A procedure for producing a dough such as rice cake using the above-structured steaming machine will be described below.
First, new powder, water, sugar and other materials are charged into the steaming chamber 28 from the charging port 24 of the stirring vessel 17. Next, the drive device 23 is driven to rotate the drive shaft 18 via the sprockets 21 and 22 and the chain 20, thereby rotating the stirring blade 19 via the blade boss 46 and stirring for an appropriate short time. .
[0040]
After closing the opening / closing lid 26 of the charging port 24, steam is sent into the steaming chamber 28 by the steam ejection device 34 and the steam supply device 57.
That is, in the steam ejection device 34, the steam supply valve 33 is opened, and steam is ejected from the steam supply source into the steaming chamber 28 through the header 32, the steam pipe 31 and the steam outlet 30.
[0041]
In the steam supply device 57, the steam supplied from the steam supply source 58 is opened via a steam pipe 59, a steam supply pipe 61, a blade boss 46, and a steam introduction pipe 62 by opening a steam supply valve (not shown). From the steam delivery hole 68, the stirring blade 19 is sent to the steaming chamber 28 toward the rear side in the traveling direction. Here, the steam that has passed through the steam supply path 64 of the steam supply pipe 61 is discharged into the space 45 at the blade boss 46 and introduced into the steam introduction pipe 62 from the space 45.
[0042]
When the stirring blade 19 is rotated while being supplied with steam, the material accumulated on the lower inner peripheral surface 28a of the steaming chamber 28 due to its own weight is moved along the axial direction of the steaming chamber 28 by the rotating spiral portion 47. It is transferred forward. At this time, since the front of the steaming chamber 28 is closed by the opening / closing lid 27, the material transferred forward is moved from the lower inner peripheral surface of the steaming chamber 28 to the center of the spiral portion 47 by the opening / closing lid 27. The horizontal bar portion 48 is dropped by its own weight through the vacant space A to the central portion or the rear portion of the lower portion of the steaming chamber 28 and is divided or bent in the lateral direction by the horizontal bar portion 48 of the crank portion 49. Kneaded by.
[0043]
During this time, the steam delivered from the steam delivery hole 68 near the material mainly acts on the inner surface of the fabric, and the steam ejected from the steam outlet 30 mainly acts on the outer surface of the fabric, so that the entire fabric is evenly distributed, And it can be steamed in a short time. Further, since the steam delivery hole 68 is disposed on the rear side in the traveling direction of the stirring blade 19, clogging is not caused by the dough. In addition, when giving a firmness to dough, it is also possible to drive and steam only the steam supply device 57 without operating the steam ejection device 34.
[0044]
Thus, after steaming for a predetermined time is finished and a high-temperature paste product is generated, the steam ejection device 34 and the steam supply device 57 are stopped while the stirring blade 19 is rotated, the exhaust valve 39 is closed, The on-off valve 36 is opened and the vacuum device 37 is operated.
[0045]
As the atmospheric pressure decreases, moisture contained in the paste product is vaporized at a low temperature, and the temperature of the paste product is lowered by taking heat of vaporization from the paste product. There are a method for checking the temperature of the kneaded product with a temperature sensor installed on the inner wall of the kneading chamber 15 and a method for estimating it from the degree of vacuum in the kneading chamber 28. The vacuum device 37 is stopped.
[0046]
Then, when the dough is taken out after the inside of the steaming chamber 28 is returned to atmospheric pressure, the stirring blade 19 is rotated with the open / close lid 27 open to adhere to the lower inner peripheral surface of the steaming chamber 28. The dough that is being pressed can be forcibly pushed forward and discharged automatically from the take-out port 25, and the work of taking out the material becomes extremely easy.
[0047]
In the steamer of the present embodiment, the steam supply pipe 61 having the steam supply path 64 is disposed with a gap 63 interposed between the drive shaft 18 and the gap 63 functions as a heat insulating layer. Even if the temperature of the steam supply pipe 61 rises due to this heat, this heat can be suppressed from being transmitted to the drive shaft 18. Therefore, it can suppress that the temperature of the bearing apparatus 43 and the bearings 44 and 44 which are supporting the drive shaft 18 rises, and it can prevent that these functions are damaged beforehand.
[0048]
Further, since the gap 63 is opened to the outside by the air vent 67 and the air in the gap 63 circulates with the external air, it is possible to further suppress the air temperature of the gap 63 from rising. In addition, the steam supply pipe 61 and the drive shaft 18 can be directly cooled by external air.
[0049]
Furthermore, in the steaming machine of the present embodiment, the stirring blade 19 includes the spiral portion 47 made of a square plate material and the crank portion 49 having the horizontal bar portion 48. While being continuously transferred along the axial direction of the kneading chamber 28, it is kneaded while being divided and bent mainly by the crank portion 49, so that good stirring and kneading can be performed. Since the portion 47 is formed of a square plate material, the dough is pushed by a surface instead of a line, and the transfer efficiency of the dough can be improved and the kneading can be further improved as compared with the case of using a round bar or the like. . In addition, since the stirring blade 19 and the steam introduction pipe 62 are configured separately, it is not necessary to form a complicated steam flow passage in the stirring blade 19 and the manufacturing operation is facilitated.
[0050]
Further, in the steaming machine of the present embodiment, the steam ejection device 34 and the steam supply device 57 are selectively used, so that each device can be used properly according to the dough to be steamed. Increases nature. Further, when both devices 34 and 57 are used, steam can be applied to the inner and outer surfaces of the dough, so that the dough can be finished softly and the steaming time can be greatly shortened. Furthermore, since these devices 34 and 57 are arranged in separate systems, the steam pressure decreases due to the branch supply of steam, and the amount of steam blown out becomes unstable as in the case where the systems are configured in the same system. It is possible to prevent the steam outlet 30 and the steam delivery hole 68 from being clogged and the quality of the product from being deteriorated.
[0051]
FIG. 8 thru | or FIG. 11 is a figure which shows 2nd Embodiment of the steamer of this invention.
In this figure, the same reference numerals are given to the same elements as those of the first embodiment shown in FIGS. 1 to 7, and the description thereof is omitted.
The difference between the second embodiment and the first embodiment described above is the configuration of the stirring blade and the blade boss.
[0052]
That is, as shown in FIG. 8, the blade boss (boss member) 46a is provided with a stirring blade 19a and a screw blade (projection) 69 on the outside, and a space 45 is formed on the inside as shown in FIG. It is substantially cylindrical and is coaxially assembled to the distal end side of the drive shaft 18 so as to be located in the steaming chamber 28.
[0053]
In the stirring blade 19a, stay portions 70, 70 are provided in parallel to each other at an appropriate interval in the axial direction so as to be orthogonal to the blade boss 46a, and the horizontal bar portion is parallel to the axis between the tips of the stay portions 70, 70. A pair of agitating portions 72, 72 to which 71 is attached is provided by being shifted by 180 degrees and appropriately shifted in the axial direction.
[0054]
Further, the stirring blade 19a has a steam introduction pipe 62 having one end opened to the space 45 of the blade boss 46a through a hole (not shown) at the inner edge of the stay portions 70, 70 and the horizontal bar portion 71 starting from the blade boss 46a. It is arranged in a U shape along. As shown by the arrows in FIG. 10, when the stirring blade 19a rotates counterclockwise around the rotation axis L, the steam introduction pipe 62 is disposed on the rear side in the traveling direction of the stirring portions 72 and 72 of the stirring blade 19a. It is attached by joining means, such as welding, so that it may be located. The steam introduction pipe 62 is provided with a plurality of steam delivery holes 68 at regular intervals of about 10 cm toward the rear side in the traveling direction.
[0055]
The screw blade 69 transfers material adhered to the outer peripheral surface of the blade boss 46a. The screw blade 69 projects in a spiral shape (left screw direction) around the axis on the outer peripheral surface of the blade boss 46a. Further, as shown in FIG. 11, through holes 73 are provided at regular intervals along the screw blades 69 in the blade boss 46 a. The through-hole 73 is formed so as to penetrate the space 45 formed inside the blade boss 46a and to be positioned on the rear side in the traveling direction of the screw blade 69 when the blade boss 46a rotates around the rotation axis L. Has been.
Other configurations are the same as those in the first embodiment.
[0056]
In the steaming machine configured as described above, any of the kneading materials adhering to the lower inner peripheral surface of the steaming chamber 28 by passing the horizontal bar portion 71 of the stirring unit 72 in the vicinity of the inner peripheral surface 28a of the steaming chamber 28 is selected. Scoop up with the horizontal bar 71 of one stirring unit 72. The scooped dough drops by its own weight when it is lifted to almost right above, and is then divided in the vertical direction by the stay part 70 of the other stirring part 72 and the horizontal bar part 71 of the other stirring part 72 Therefore, good stirring and kneading can be performed.
[0057]
The semi-kneaded dough that adheres to the outer peripheral surface of the blade boss 46a among the dough that has fallen by its own weight is transferred forward by the rotation of the screw blade 69, and steam is supplied from the through hole 73 during the transfer. However, mixing is improved by kneading with the screw blades 69. Furthermore, it is possible to prevent the fabric from being entangled with the blade boss 46 a by transferring the fabric and blowing out the steam from the through hole 73.
With respect to the configuration other than the stirring blade and the blade boss, the same actions and effects as those of the first embodiment can be obtained.
[0058]
In addition, in the said embodiment, although it was set as the structure which installs the stirring container 17 horizontally, it is not restricted to this, Even if it is a vertical half-rotation type stirring container, it is applicable.
Further, a cooling device that sends cooling air to the gap 63 between the drive shaft 18 and the steam supply pipe 61 may be provided to prevent the temperature of the drive shaft 18 and the steam supply pipe 61 from rising.
[0059]
【The invention's effect】
  As described above, in the steamer according to the first aspect, the steam supply pipe connected to the steam supply source with a gap formed between the drive shaft and the steam supply source is inserted into the drive shaft, and the agitating blade is moved backward in the traveling direction. A steam introduction pipe having a steam delivery hole which is located at the rear side and is bored toward the rear side is attached. Thereby, in this steaming machine, since the gap functions as a heat insulating layer, even if the temperature of the steam supply pipe rises due to the heat of steam, it is possible to suppress the transfer of this heat to the drive shaft. Further, it is possible to suppress an increase in the temperature of the bearing device or the bearing that supports the drive shaft and to prevent the functions from being damaged in advance.
  In addition, the stirring blade has a configuration including a spiral portion made of a square plate material and a crank portion arranged to face the spiral portion.

  Claim 4In the steamer according to the above, the steam supply device and the steam ejection device are arranged in separate systems, and can be selectively used.
  As a result, in this steaming machine, versatility is enhanced by arbitrarily using each device according to the dough to be steamed, and when both devices are used, steam is applied to the inner and outer surfaces of the dough. As a result, the dough can be finished soft and the steaming time can be shortened. Furthermore, since these devices are arranged in a separate system, as when configured in the same system, it is possible to prevent the steam pressure from being lowered due to the branch supply of steam and the amount of steam blown out to be unstable, There is also an effect that it is possible to prevent the steam outlet and the steam delivery hole from becoming clogged and deteriorating the quality of products.
