[0001]

[Industrial applications]

 The present invention relates to a food steaming machine suitable for use in mixing, kneading, steaming, and the like of food materials such as new powder, fertilizer powder, and fish meat.

[0002]

[Prior Art]

 Conventionally, this type of food kneader has a material injection port and a dough extraction port, each of which can be sealed by a lid, an inside is formed into a kneading chamber, and an outside is provided with a jacket. A kneading container, a rotary shaft that is inserted into the kneading container with the tip end protruding into the kneading chamber, and is driven to rotate in a predetermined direction by a drive source, and extends in the radial direction of the kneading chamber. In this state, the stirring blade is provided on the tip side of the rotary shaft, and is roughly composed of one steam injection hole that is formed on the rear wall of the kneading chamber and blows steam into the kneading chamber. There is.

When, for example, new powder is steamed using the food steamer described above, appropriate amounts of new powder, water and necessary additives such as sugar and pigment are put into the steaming chamber through the material inlet. After mixing the materials by rotating a stirring blade, steam is blown into the kneading chamber through a steam blowing hole for a predetermined time to steam the mixture while kneading the mixture to produce a dough.

[0004]

[Problems to be solved by the device]

 By the way, in the prior art as described above, since one steam injection hole is provided in the rear wall portion of the kneading vessel, there are the following drawbacks. The first point is that if the steam blowing pressure is weak, the steam is supplied only to the surface side of the mixed material, so that a steamy dough is produced. The second point is that in order to prevent the steaming unevenness to some extent, it is sufficient to increase the steam pressure and supply a large amount of steam, but as a result, steam consumption increases and operating costs increase. is there.

Further, the third point is that since the steam injection hole is located in the rear wall portion, the injection hole is easily clogged with the material. For this reason, there is the inconvenience that the kneading work of mixing other materials into the dough cannot be performed without blowing steam, and the clogging must be removed after the kneading process. The fourth point is that since it is difficult to evenly supply steam to the mixed materials, it is necessary to supply a large amount of steam even when kneading a small amount of material, and the dough is too soft. Is possible.

The present invention has been made in view of the above-mentioned drawbacks of the prior art, and provides a food kneader capable of uniformly supplying a small amount of steam to a material and preventing clogging of steam outlet holes. It is provided.

[0007]

[Means for Solving the Problems]

 The features of the means of the present invention configured to solve the above-mentioned problems are that a rotary shaft is provided with a steam supply passage in the axial direction, and the stirring blade is connected to the steam supply passage to rotate the stirring blade. This means that a plurality of steam outlets were provided to blow steam in the opposite direction.

[0008]

[Action]

 The stirring blade provided on the rotating shaft rotates in a predetermined direction in the kneading chamber to mix the materials and the like. During this time, steam is blown out from the plurality of steam blowout holes of the stirring blade in the direction opposite to the rotation direction, and is uniformly supplied to the entire material.

Next, the operation of the food kneader of the present embodiment having the above configuration will be described. First, water, materials such as powder and necessary additives such as sugar are charged from the charging port 3 into the kneading chamber 5 in which the dough discharging port 4 is closed by the discharging port cover 8, and the charging port cover 6 is closed. It Next, the electric motor 16 is started, and the stirring blade 26 is rotated in the direction of arrow A through the rotary shaft 19 to mix the materials for a predetermined time.

Thereafter, the steam generated by a boiler (not shown) and set to a predetermined steam pressure by the pressure reducing valve is supplied into the steam supply passage 20 of the rotary shaft 19 through the airtight rotary joint 24. The supplied steam is blown into the stirring blade 26 through the axial communication hole 27B, and is blown into the stirring blade 26 from each steam supply hole 21 through the radial communication hole 27B, and then the stirring blade 26. It is jetted into the kneading chamber 5 from each steam blowing hole 34 in the direction of arrow B, which is the opposite direction to the rotational direction A of 26. During this period, steam for heating is supplied from the upper supply / discharge pipe 14 into the jacket chamber 11.

Then, while the stirring blades 26 rotate, the steam can be blown evenly to the whole of the mixed material from the large number of steam blowing holes 34 toward the other side of the rotating direction A, and as a result, there is no unevenness in steaming. You can steam different dough. Moreover, the steam blow-out holes 34 are not clogged, and it is possible to knead in a short time with a small amount of steam as compared with the prior art.

When the steaming of the dough is completed as described above, cooling water is supplied to the jacket chamber 11 from the lower supply / exhaust pipe 13 in place of the steam, and the dough is cooled to complete the work.

Further, according to the present embodiment, in addition to the above-described steaming treatment, a kneading treatment for mixing the additive with the dough while heating without steam being blown can be performed. That is, steam is supplied into the jacket chamber 11 through the upper supply / discharge pipe 14, and the dough and the additive are mixed by the stirring blade 26 while maintaining the container body at a predetermined temperature. In this case, since the steam blow-out holes 34 are provided in the direction B opposite to the rotating direction A of the stirring blade 26, the steam blow-out holes 34 will not be clogged with the material even if the steam is not blown out. Therefore, maintenance after work can be done easily.

Moreover, according to the present embodiment, since the tip side 13A of the lower supply / discharge pipe 13 is extended to the front end of the jacket 10, the cooling water can be circulated throughout the jacket chamber 11. Therefore, it is possible to manufacture a uniform dough without unevenness in kneading.

In the present embodiment, the horizontal type kneading vessel 1 is shown, but according to the present invention in which the steam blowing holes 34 are provided in the stirring blade 26, a vertical half-rolling type kneading vessel is provided. It can also be configured as a food steamer.

[0028]

[Effect of the device]

 As described in detail above, the present invention has the following effects because the stirring blade is provided with a plurality of steam blowout holes in the direction opposite to the rotating direction. The steam blow-out holes will not be clogged with the material, not only when steam is blown out but also when kneading is performed without blowing out steam. Since the steam can be uniformly supplied to the entire material through the plurality of steam outlets, it is possible to knead a high-quality dough without steaming unevenness in a short time with a small amount of steam. As a result of being able to quickly supply steam to the entire material, it becomes possible to adapt the steam supply amount to the amount of material, and it is possible to produce a dough of the same quality in both large-scale steaming and small-scale steaming. it can.
