Description

[Detailed Description of the Invention] (Industrial Application Field) This invention is applicable to raw noodles such as raw udon, ramen, and soba;
This invention relates to a grain flour kneading and extrusion cooking device for making pasta such as spaghetti.

(Prior art) Conventionally, when producing this type of raw noodles using a machine, powder such as wheat flour and salt water are kneaded in a kneading device, and then the kneaded dough is rolled in a device separate from the kneading device. The fabric is then cut by hand using a knife.

(Problem to be solved by the invention) However, in this case, ``■ Since kneading and cutting are performed separately, there are many manual steps and it is troublesome.

■Since kneading and cutting are performed in separate devices, there are many parts to be cleaned after noodle making, and a large amount of space is required to place the devices.

``The structure of the device is complex, and the cost of the device itself is high.''

Therefore, this invention is a grain flour kneading extrusion method that is low cost, compact, does not require a large space, has a relatively simple structure, can easily produce noodles, etc., and has a finished amount suitable for general households. The purpose is to provide a molded cooking device.

(Means for Solving the Problems) In order to achieve this object, in the grain flour kneading extrusion cooking device of the present invention, a hollow container that extends horizontally in an elongated manner is provided in the main body in which the drive device is built, and the A screw for kneading and conveying linked to an output shaft is disposed concentrically and rotatably within the hollow container, a hopper extending vertically in a cylindrical shape is provided at the upper part of the main body side of the hollow container, and an opening at the tip of the hollow container is provided. The part is closed by a multi-hole nozzle disk provided with a large number of nozzles, and the drive device is provided with a rotation direction switching means for switching the rotation direction of the output shaft between forward and reverse, and the output shaft When the output shaft rotates in one direction, the screw kneads the material, and when the output shaft rotates in the other direction, the screw transports and extrudes the material.

Further, when the material is kneaded, the connection direction of the winding of the drive motor of the drive device is switched to a direction with good motor efficiency, and when the material is conveyed and extruded, the connection direction of the drive motor is switched in the opposite direction. A switch is used as the rotation direction switching means.

Furthermore, the pitch of the screw blades of the screw is
Among the parts corresponding to the hopper, the part from the center of the hopper to the nozzle side is the largest, and the pitch becomes smaller toward both ends from the largest part.

Furthermore, a material pushing rod having a semi-cylindrical recess with a curvature corresponding to the curvature of the outer diameter of the screw blade provided on the screw is inserted into the hopper, and the material pushing rod is provided with a distal end portion and an engaging portion provided on the peripheral wall. The hopper is provided with a first locking portion capable of locking the engaging portion at a position where the tip of the material pushing rod corresponds to the frontage end into the hollow container of the hopper, and the recess is located in the screw blade. A second locking portion capable of locking the engaging portion at a corresponding position is provided on the hopper.

Further, a flexible tongue extending toward the screw is provided at the center of the recess.

The screw is made of a material having a smaller coefficient of friction than the hollow container.

The shaft portions forming the concave conveyance path of the screw have different diameters in the circumferential direction.

(Function) According to such a configuration, by rotating the output shaft of the grain flour kneading extrusion molding cooker in one direction, the material is kneaded by the screw while the material is flowing back inside the hollow container. On the other hand, by rotating the output shaft in the other direction, the kneaded dough is extruded from the nozzle by the screw, and the extruded dough is formed into noodles with a cross section corresponding to the nozzle shape.

Furthermore, if the direction of connection of the windings of the drive motor of the drive device is immediately switched to a more efficient direction, the materials can be kneaded efficiently, and if the direction of connection of the windings of the drive motor of the drive device is switched in the opposite direction. Then, the kneaded material is extruded from the nozzle by the screw.

Furthermore, the pitch of the screw blades of the screw is
Of the parts corresponding to the OQ hopper, the part from the center of the hopper to the nozzle side is the maximum, and this pitch is smaller than the maximum part, as the rows are smaller than the maximum part, so when kneading materials or extruding dough, the material The compressive force of the fabric gradually increases.

Moreover, when the engaging part is locked with the first locking part, the leading end of the material pushing rod corresponds to the opening end of the hopper into the hollow container. In this "position, a space for material circulation is formed between the recess of the best push rod and the screw. Also, when the engaging part is locked with the second locking part, the recess is connected to the screw blade. Correspondingly, no gap is created between this concave portion and the screw blade of the screw, resulting in a state suitable for extrusion of dough by the screw.

Further, by providing a flexible tongue extending toward the screw in the center of the recess, when the engaging portion is locked with the second locking portion, the recess corresponds to the screw blade. Since the flexible tongues invade the sides of the screw blades of the screw, the flexible tongues scrape off the dough that adheres to the surface of the screw during dough extrusion.

Since the screw is made of a material having a smaller coefficient of friction than the hollow container, the dough can be smoothly extruded without the kneaded material sticking to the screw.

By varying the diameter in the circumferential direction of the shaft portion forming the concave conveyance path of the screw, the material undergoes repeated compression and relaxation as the screw rotates.

Next, the operation of the grain flour kneading extrusion cooking device having such a structure will be explained.

Position the connection direction switch S to the "turn" or kneading side, and select the terminal? ,,T,each other and Ts,? When the wires are connected by the connection direction switch S, the drive motor 3 is rotated in the normal direction, and the rotational force of the drive motor 3 is reduced in speed through the reduction gear 5 and then transmitted to the screw 22, so that the screw 22 rotates in the normal direction. be turned over.

On the other hand, the connection direction switch S is positioned on the "extrusion" side, that is, on the conveyance/extrusion side, and the terminals a, Ts and Ts are
, Ts are connected to each other by the connection direction changeover switch S, the drive motor 3 is reversed, and the rotational force of the drive motor 3 is decelerated via the reduction gear 5 and then transmitted to the screw 22, and the screw 22 is reversed. I am made to do so.

Therefore, when making noodles, such as fresh udon noodles, as shown in FIG. 9, first, an appropriate amount of the material 31, which is a mixture of wheat flour, salt water, etc., is put into the hopper 15, and then the material push rod 27 is inserted into the hopper 15. Then, the engaging portion 29 of the material pushing rod 27
is locked in the first locking part 16a as shown in FIG. Lock and fix. In this position, for example, Fig. 3, Fig. 21,
As shown in FIG. 22, a gap is formed between the recess 28 and the screw 22.

On this edge, the drive motor 3 rotates the screw 22 in the normal direction. As a result, the material 31 is moved by the screw blade 24 to the right in FIG.
are moved in this order. According to the screw 22 shown in FIGS. 16 to 18, due to the action of the protrusion 25 and the notch 26, the material 31 does not stay at the position m4, but moves into the recess 28 of the material pushing rod 27. and returned to the ml position. Here, the screw blade 24
Since the pitch of the material 31 gradually becomes smaller as it goes toward the end wall 24a side, the material 31 receives a gradually larger compressive force as it goes toward the end wall 24a side.
When moving from m to position m, it no longer receives compressive force. By continuing the reflux operation of compressing and relaxing the material 31 in this way, the material 31 is sufficiently kneaded as shown in FIG.
It accumulates in the range W in Fig. 23. Incidentally, due to this operation, the screw 22 receives thrust to the left, so there is a gap l! between the thrust washer TW and the wall portion 11b as shown in FIG. Jla is formed.

After such kneading is performed, the locking portion 2 of the material pushing rod 27
9 is locked to the second locking part 17a as shown in FIG. As a result, the flexible tongue piece 30 protrudes into the conveyance path 24b of the screw blade 24 as shown in FIGS. 28 and 29. In this state, when the screw 22 is reversed by the drive motor 3, the material 3
1, the dough is conveyed to the multi-hole nozzle disk 19 while being compressed by the action of the screw blades 24. Then, this material 31 is extruded from the nozzle 19a of the multi-hole nozzle disk 19 as shown in FIG. 28, and becomes string-like raw noodles. At this time, the flexible tongue piece 30 scrapes off the material adhering to the screw blade 24 at the portion facing the hopper 15 so that no material remains on the surface of the screw 22. Incidentally, with this operation, the screw 22 receives a rightward thrust, and this thrust is received by the thrust washer TV as shown in FIG. 27.

In the embodiment described above, the coupling between the screw 22 and the output shaft 6 is composed of the engagement groove 7 provided on the output shaft 6 and the flat engagement protrusion 23a provided on the screw 22, but this is not necessarily the case. For example, but not limited to,
As shown in FIGS. 36 and 31, a hexagonal engagement protrusion 32 is provided on the shaft portion 23 of the screw 22 as shown in FIG.
By providing a hexagonal engagement hole 33 on the output shaft 6 and fitting the engagement protrusion 32 into the engagement hole 33, the engagement protrusion 32 and the engagement hole 33 form a coupling. You may do so.

Further, although the screw blade 24 is provided with an end wall 24a and the end wall 24a is provided with a notch 26, the structure of the end of the screw 22 is not necessarily limited to this. For example, Without providing the above-mentioned end wall 24a, the third
As shown in FIG. 3, one arc-shaped protrusion 34 is simply provided on the end face of the screw blade 24, or two arc-shaped protrusions 34 are provided as shown in FIG. 34, or as shown in FIG. It is also possible to adopt a configuration in which linear protrusions 35 are provided as shown in FIG.

Further, in the above-described embodiment, an example was shown in which the cross-sectional shape of the shaft portion 24d of the screw blade 24 was formed into a circular shape, but the shape is not necessarily limited to this.

For example, as shown in FIGS. 36 and 37, the cross-sectional shape of the shaft of the screw blade 24, that is, the cylinder shaft ^X that forms the concave and spiral conveyance path 24b, is set to an eccentricity of minimum radius rl + maximum radius r2. Alternatively, as shown in FIG. 42, the radius of the cylindrical axis AX of the screw blade 24 may be formed in multiple stages of r and xr in the circumferential direction. It is also possible to have a structure with unevenness. In these cases,
As the screw blade 24 rotates, the material is transferred to the screw 2.
While being conveyed in the longitudinal direction of 2, the compressing and loosening operations are repeated, which corresponds to the operations such as hand-pounding, kneading, and stepping performed by a skilled person when making noodles. And the 38th
In the case of the embodiment shown in the figure, such compression and relaxation operations are performed many times in one rotation of the screw blade 24, so even if the material is conveyed at a low speed, the compression and relaxation operations per unit time are
This means that you have done more relaxing work, and you can effectively perform work that corresponds to movements such as hand clapping, hand kneading, and foot stomping.

Further, the material pushing rod 27 described above can also be formed from polyethylene resin, polypropylene, etc. In this case, the flexible tongue piece 30 is formed into a cylindrical shape or a rectangular shape (not shown) as shown in FIG. can. Furthermore, the flexible tongue piece 30
If a thin hinge is provided at the base of the material push rod 27 as shown in FIGS. 40 and 41, the material for the material push rod 27 can be selected from a wider range of materials, so the material push rod 27 and the flexible tongue piece 30 can be manufactured at low cost.

A screw for kneading and conveying that is interlocked with the output shaft of the drive device is disposed concentrically and rotatably within the hollow container, and a hopper extending vertically in a cylindrical shape is provided at the upper part of the main body side of the hollow container. The opening at the tip of the container is closed by a perforated nozzle disk provided with a large number of nozzles, and the drive device is provided with a rotation direction switching means for switching the rotation direction of the output shaft between forward and reverse. When the output shaft rotates in one direction, the screw kneads the material, and when the output shaft rotates in the other direction, the screw transports and extrudes the material,
It is low cost, small size, and does not require large space.
It is possible to provide a grain flour kneading and extrusion cooking device which has a relatively simple structure, can easily manufacture noodles, etc., and can produce a quantity suitable for general households.

Further, when the material is kneaded, the connection direction of the winding of the drive motor of the drive device is switched to a direction with good motor efficiency, and when the material is conveyed and extruded, the connection direction of the drive motor is switched in the opposite direction. When a switch is used as the rotation direction switching means, the driving force of the motor can be used efficiently enough when kneading materials that require a large torque.

Furthermore, the pit t of the screw blade of the screw is
Among the parts corresponding to the hopper, the part from the center of the hopper to the nozzle side is the largest, and if this pitch is made smaller toward both ends than the maximum part, the compression pressure of the material can be gradually increased as it is conveyed. .

Furthermore, a material pushing rod having a semi-cylindrical recess with a curvature corresponding to the curvature of the outer diameter of the screw blade provided on the screw i- is provided at the tip and an engaging portion is provided on the peripheral wall, and is inserted into the hopper. , the hopper is provided with a first locking portion capable of locking the engaging portion at a position where the leading end of the material pushing rod corresponds to the opening end into the hollow container of the hopper; When the hopper is provided with a second locking portion capable of locking the engaging portion at a position corresponding to the blade, when the engaging portion is locked with the first locking portion,
A leading end of the material pushing rod corresponds to an open end of the hopper into the hollow container. At this position, a space for material reflux is formed between the recess of the best push rod and the screw, and the material can be moved and kneaded using this space during kneading of the material. Furthermore, when the engaging portion is locked with the second locking portion, the recess corresponds to the screw blade, and no gap is created between the recess and the screw blade of the screw, and the fabric is removed by the screw. The state can be made suitable for extrusion.

Further, when a flexible tongue extending toward the screw is provided in the center of the recess, the engaging portion is locked to the second locking portion so that the recess is engaged with the screw blade. By doing so, when no gap is created between this concave portion and the screw blade of the screw, the flexible tongue protrudes into the conveyance path of the screw blade and scrapes the dough from the screw blade during dough extrusion. This prevents it from falling and sticking to the surface.

If the screw is made of a material with a lower coefficient of friction than the hollow container, it will prevent the material or dough from adhering to the surface of the screw blades and making it difficult to move, and this will prevent the material or dough from adhering to the surface of the screw blades and making it difficult to move. You can easily travel through time.

When the circumferential diameters of the shaft portions forming the concave conveyance path of the screw are made different, the material undergoes repeated compression and relaxation as the screw rotates, so that when an expert makes noodles, etc. Able to perform movements equivalent to manual clapping, massaging with nine hands, nine foot pedals, etc.
