Description

  The present invention relates to a method and apparatus for producing seaweed noodles mainly composed of seaweeds.

  The manufacturing method of the noodle which has seaweed as a main component is known conventionally, and if it classify | categorizes according to the form of the noodle manufactured, the manufacturing method (for example, refer patent document 1) shape | molded in the form of a thread | yarn, and the manufacturing shape | molded in a strip shape A method (see, for example, Patent Document 2) is known.

  In the former production method, seaweeds are treated with an alkaline solution to form a mud, then mixed until there is no solid content, the resulting liquid is concentrated, and the concentrate is passed through a nozzle into a calcium chloride solution. The filamentous seaweed noodles are obtained by extruding and solidifying into filaments, neutralizing the filamentous solids with an acid solution and washing with water. As the nozzle for extrusion forming into a yarn shape, a spinneret type is used.

  The seaweed noodles, which are thinly shaped into a strip, can be eaten as they are with vinegar soy sauce, mixed with salads, etc., and they have a good texture, so an increase in production is expected.

  However, seaweed noodles contain alginic acid as a component, and this alginic acid has a function of increasing the surface tension. Therefore, seaweed noodles that have been extruded flat in the coagulation liquid become agglomerated in the vicinity of the nozzle outlet. In many cases, it was difficult to produce stably.

  The present invention has been made in view of the problems in the conventional method for producing seaweed noodles as described above, and prevents the seaweed noodles extruded from the nozzle from solidifying in a lump and continuously forming flat strips of seaweed noodles. The present invention provides a method and apparatus for producing seaweed noodles that can be stably produced.

  The method for producing seaweed noodles of the present invention is a method for producing seaweed noodles in which a raw material obtained by gelling seaweeds is extruded into a coagulating liquid from a plurality of discharge nozzles, and the coagulating liquid is introduced into a water channel by introducing the coagulating liquid into the water channel. A flow is formed, and a plurality of discharge nozzles are immersed in the coagulation liquid in a state substantially parallel to the flow direction of the coagulation liquid, and the raw material is pushed out from the discharge nozzles while flowing the coagulation liquid along the outer peripheral wall of each discharge nozzle. This is the gist.

  According to the present invention, since the raw material is extruded from the discharge nozzle while flowing the coagulating liquid along the outer peripheral wall of each discharge nozzle, a tensile force due to the flow of the coagulating liquid acts on the raw material extruded from the discharge nozzle. Thereby, it becomes possible to make noodles without agglomerating the seaweed noodles immediately after being extruded from the discharge nozzle.

  In the above manufacturing method, it is preferable to flow the coagulation liquid through the water channel at a speed equal to or higher than the extrusion speed of the raw material extruded from the discharge nozzle.

  The seaweed noodle production apparatus of the present invention is a seaweed noodle production apparatus for producing noodles by extruding a raw material obtained by gelling seaweed into a coagulation liquid from a plurality of discharge nozzles. A plurality of discharge nozzles immersed in the coagulation liquid in a state substantially parallel to the flow direction of the coagulation liquid so that the coagulation liquid flows along the outer peripheral wall of each discharge nozzle. The gist.

  In the manufacturing apparatus, the front end side end surface of the discharge nozzle can be formed flat or circular.

  Moreover, in the structure which connects the container part which stores a raw material to the upstream end of the said coagulation liquid water supply path, a some discharge nozzle can be extended from this container part.

  Moreover, in the structure which immerses the container part which stores a raw material in the upstream part of the said coagulation liquid water supply path, a some discharge nozzle can be extended from this immersion container part.

  Moreover, in the structure which arrange | positions the said coagulation liquid water supply path substantially horizontal, and arrange | positions the container part which stores a raw material above the upstream part, each delivery pipe hung down from this container part is discharged through a bending part. Can be connected with a nozzle.

  In addition, by having a coagulation liquid supply pipe for supplying the coagulation liquid to the upstream part of the coagulation liquid water supply path, and by connecting a variable capacity type pump for adjusting the supply amount of the coagulation liquid to the coagulation liquid supply pipe, The flow rate of the coagulating liquid flowing through the coagulating liquid water channel can be adjusted.

  In addition, if a coiled winding tube wound around a vertical axis is connected to the downstream portion of the coagulating liquid water passage, and the number of turns of this winding tube is selected, the height difference between the inlet and outlet of the winding tube The flow rate of the coagulating liquid in the coagulating liquid water channel can be adjusted.

According to the method and apparatus for producing seaweed noodles of the present invention, since the linearity of seaweed noodles extruded from the discharge nozzle is maintained, the algae noodles extruded from the nozzles are prevented from being agglomerated, and the striped seaweed noodles are continuously formed. Can be manufactured stably.
Moreover, since it becomes possible to arrange | position a discharge nozzle closely, the production efficiency of seaweed noodles can be improved.

  Hereinafter, the present invention will be described in detail based on the embodiments shown in the drawings.

  FIG. 1 is a perspective view showing a first embodiment of a seaweed noodle production apparatus according to the present invention.

  In the figure, as a raw material supplied to the seaweed noodle production apparatus 1, a material in which seaweed such as kelp, laver, young cloth, hijiki, etc. is dissolved can be used.

  Specifically, after washing the young cloth with water, sodium carbonate is added and heated and stirred to make a paste-like melt, which is used as a raw material. A calcium chloride aqueous solution is used as a coagulating liquid for coagulating the raw material.

  The seaweed noodle production apparatus 1 is mainly composed of a nozzle device 2 for extruding a raw material, and a coagulating liquid water supply path 3 in which the flow of the coagulating liquid is formed and the nozzle device 2 is immersed.

<Nozzle device>
The nozzle device 2 has a container part 4 made of a hollow rectangular container, and a raw material supply pipe 5 for supplying a raw material to the container part 4 is connected to the upper part thereof.

  One of the side walls constituting the container part 4 is constituted by a forming die 6 for forming the gelated raw material into a strip shape, and the container part 4 and the forming die 6 are connected and integrated. Yes.

  FIG. 2 is an enlarged view of the molding die 6, wherein (a) is a front view and (b) is a side view.

  In both figures, the forming die 6 is composed of a rectangular thick plate member, has a plurality of slit-like discharge ports 6 a on the surface, and a flat passage 6 b communicating with the discharge ports 6 a penetrates the inside of the forming die 6. Is provided.

  In the present embodiment, the discharge ports 6a are formed in 12 rows, 3 rows in the row direction and 4 columns in the column direction, and a total of 12 discharge ports 6a are shown. As an example of the size of the discharge ports 6a, the gap t is 0.5 mm and the width w is 22.5 mm. The vertical interval Sv between the discharge ports 6a is 10 mm, and the horizontal interval Sh is 5 mm. Thus, each discharge port 6a is arrange | positioned in the state which adjoined.

  Returning to FIG.

  Each discharge port 6a of the forming die 6 is connected to one end of a nozzle 7a obtained by processing a metal pipe into a flat shape, and a flat passage 6b of the forming die 6 communicates with the nozzle 7a and is extended. Yes.

  Each nozzle 7a is arranged so as to be parallel to each other in the horizontal direction, and constitutes a nozzle group 7 as a whole.

  The gap between the nozzles 7a becomes a flow path through which the coagulating liquid flows, and the coagulating liquid flows along the outer peripheral wall of each nozzle 7a. In addition, the length of the nozzle 7a in a water supply groove 3b described later needs to be at least 80 mm. When the length of the nozzle 7a in the water supply groove 3b is less than 80 mm, it tends to be agglomerated under the influence of turbulent flow when extruding the raw material from the nozzle 7a.

<Coagulating liquid water channel>
The coagulating liquid water passage 3 is formed in a bowl shape with an open top, and a reservoir 3a for accommodating the container part 4 is formed in a rectangular shape (as viewed from the plane) at the upstream portion thereof. A water supply groove 3b is formed from one place on the side wall of the reservoir 3a.

  A downstream end (not shown) of the water supply groove 3b is connected to an upper entrance of a conventionally known wound tube in which the tube is wound spirally (coiled) around the vertical axis.

  Since the lower outlet of the winding tube is at a lower position than the upper inlet of the winding tube, the coagulating liquid is given a flow velocity VL due to the height difference when flowing from the water supply groove 3b to the winding tube. Further, the flow velocity VL can be adjusted by adjusting the number of turns in the winding tube.

When the extrusion rate of the raw material is ML, the flow rate VL of the coagulating liquid is
It is preferable to set VL ≧ ML.

  (a) When the flow rate VL of the coagulation liquid is slower than the extrusion speed ML, the seaweed noodles immediately after being discharged from the nozzle 7a can be prevented from agglomerating, but the formed seaweed noodles are twisted, When the thickness becomes thicker than necessary, a solidification failure occurs.

  (b) When the flow rate VL of the coagulation liquid is substantially equal to the extrusion speed ML (discharged from the nozzle), seaweed noodles with no twisting can be produced, and the thickness becomes thinner than in the case of (a) above. This eliminates poor solidification.

  (c) When the flow rate VL of the coagulation liquid exceeds the extrusion speed ML, it is possible to produce seaweed noodles with a thinner thickness (good texture) than in the case of (b) above, and the thickness becomes thinner. This further improves the solidification state.

  In addition, since the thickness of the seaweed noodles becomes thinner as the flow rate VL of the coagulation liquid is increased with respect to the extrusion speed ML, the product thickness of the seaweed noodles can be changed by adjusting the flow rate VL of the coagulation liquid.

  Further, a tip of a coagulating liquid supply pipe 8 for supplying the coagulating liquid is immersed in the storage part 3a so that the coagulating liquid is filled in the coagulating liquid water supply path 3. In addition, when the coagulating liquid in the coagulating liquid water passage 3 exceeds a predetermined water level, it is discharged to the outside through the overflow pipe 9.

  Moreover, the groove width of the water supply groove part 3b is formed narrower than the lateral width of the storage part 3a, and the flow of the coagulating liquid is accelerated and guided to the water supply groove part 3b. The nozzle group 7 is disposed in the water supply groove 3b.

<Method for producing seaweed noodles>
Next, a method for producing seaweed noodles using the seaweed noodle production apparatus 1 having the above configuration will be described.

  In FIG. 1, the coagulating liquid is filled in the coagulating liquid water passage 3 at a predetermined level, and the coagulating liquid is caused to flow in the water feeding groove 3b by flowing the coagulating liquid through the water feeding groove 3b to the winding tube.

  The raw material gelled in this state is supplied to the container part 4 through the raw material supply pipe 5.

  When the inside of the container part 4 is filled with the raw material, the raw material is sent to each nozzle 7 a through the flat passage 6 b of the molding die 6.

  The raw material formed into a strip shape by moving in the nozzle 7a is extruded into the coagulating liquid from the tip of the nozzle 7a, and solidification starts.

  The coagulating liquid flows around each nozzle 7a along the nozzle 7a, and when the flow rate VL of the coagulating liquid is set to a speed exceeding the extrusion speed VS of the raw material, the raw material extruded into the coagulating liquid from the tip of the nozzle 7a. A tensile force acts so as not to break the raw material (in the tube axis direction of the nozzle 7a).

  In this way, since the tensile force acts on the seaweed noodles extruded from the nozzle 7a in a strip shape, the seaweed noodles to be curled immediately after being extruded from the nozzles 7a are forcibly stretched straight, The seaweed noodles are prevented from adhering to each other in the vicinity of the nozzle 7a exit.

  In the above-described embodiment, the method for manufacturing the strip-shaped seaweed noodles by processing the cross section of the entire nozzle 7a to be flat has been described. However, the cross section of the flat passage 6b of the forming die 6 and the cross section of the nozzle 7a are made circular to communicate with each other. Then, it can replace with a strip | belt-shaped seaweed noodle and can manufacture a filamentous seaweed noodle.

  FIG. 3 is a perspective view showing a second embodiment of the seaweed noodle production apparatus according to the present invention.

  In the following description, the same components as those in FIG. 1 are denoted by the same reference numerals and description thereof is omitted.

  The seaweed noodle production apparatus 10 shown in FIG. 3 is different from that shown in FIG. 1 in that the container part 11 (corresponding to the container part 4 in FIG. 1) is arranged outside the coagulation liquid water passage 3 and the nozzle 7 This is the point that the cross section is changed from flat to circular.

  In this configuration, when a pasty raw material is supplied in a pressurized state to the container part 4 through the raw material supply pipe 5, the raw material is once stored in the container part 11 formed of a hollow box-like container, and the inside of the container part 11 is filled with the raw material. When it is full, each cylindrical passage 12a of the forming die 12 provided at the bottom of the container 11 is lowered and sent to each delivery pipe 13a.

  Each delivery pipe 13a suspended from the forming die 12 is bent in the L-shape from the vertical direction to the horizontal direction in the middle thereof, and the horizontal portion ahead of the bent portion 13b, that is, the nozzle 13c is a coagulated liquid feed channel. 3 is configured so as to be substantially parallel to the flow direction of the coagulating liquid flowing through the inside.

  Therefore, the raw material formed into a thread shape when moving in each nozzle 13c is extruded from the nozzle group 13 into the coagulation liquid, and solidification starts.

  Around each nozzle 13c, the coagulating liquid flows along the outer wall of each nozzle 13c. When the flow rate VL of the coagulating liquid is adjusted to a speed exceeding the extrusion speed VS of the raw material, the nozzle 13c is pushed out and tries to curl. The filamentous seaweed noodles are forcibly stretched in a straight line by the coagulation liquid flow, thereby solidifying the filamentous seaweed noodles without adhering to each other.

  In addition, when the container part 11 is disposed outside the coagulating liquid water supply path 3, turbulent flow is not generated on the downstream side of the container part, so that the coagulating liquid is faster than the nozzle group 7 shown in FIG. It becomes possible to flow along the outer wall of the nozzle 13c. Therefore, the length of the nozzle 13c can be shortened compared to the configuration shown in FIG.

  FIG. 4 is a perspective view showing a third embodiment of the seaweed noodle production apparatus according to the present invention.

  In the seaweed noodle production apparatus 20 shown in the figure, the coagulation liquid water supply path 3 is formed of a sealed rectangular tube, and the upstream end face thereof is partitioned by a forming die 21, and this forming die A container portion 22 made of a hollow rectangular container is connected to 21.

  A rectangular tube-shaped storage part 23 is installed above the upstream part of the coagulating liquid supply passage 3, and the coagulating liquid is introduced into the storage part 23 via the coagulating liquid supply pipe 8.

  In addition, when the coagulating liquid stored in the storage part 23 exceeds a predetermined water level, it is drained through the overflow pipe 9.

  In addition, each nozzle 24a extending in parallel with the coagulation liquid water supply path 3 from the molding die 21 is constituted by a straight pipe, but only its tip is processed flat to form a slit-like discharge port 24b. Yes.

  In this configuration, when the pasty raw material is supplied to the container part 22 through the raw material supply pipe 5, the raw material is once stored in the container part 22, and when the container part 22 is filled with the raw material, the container part 22 side It passes through each cylindrical passage 21a of the forming die 21 provided in the section and is sent to each nozzle 24a.

  The raw material formed into a band shape by passing through the slit-like discharge port 24b at the tip of the nozzle 24a is extruded into the coagulating liquid from the nozzle 24a and starts to coagulate.

  Around each nozzle 24a, the coagulating liquid flows along the outer wall of each nozzle 24a. When the flow rate VL of the coagulating liquid is adjusted to a speed exceeding the raw material extrusion speed VS, the coagulating liquid is extruded from each discharge port 24b in a strip shape. The seaweed noodles can be solidified without adhering to each other, and since the tensile force acts on the seaweed noodles by the flow of the coagulating liquid, the seaweed noodles to be curled immediately after being pushed out from the nozzle 24a Forcibly stretched linearly, thereby preventing seaweed noodles from sticking together.

  The nozzle 24a is formed by flattening only the end surface on the front end side of a straight pipe having a circular cross section, and the production of the nozzle is simplified as compared with the case where the whole nozzle is machined flat.

  FIG. 5 is a perspective view showing a fourth embodiment of the seaweed noodle production apparatus according to the present invention.

  The seaweed noodle production apparatus 30 shown in the figure is configured to extrude the raw material from the upstream end of the coagulation liquid water passage 3 as in the configuration shown in FIG. The raw materials are fed in this order, and seaweed noodles formed into a band shape from the discharge port 24a are extruded into the coagulation liquid.

  However, in this configuration, the reservoir 23 is not provided, and a variable capacity pump (not shown) is used to feed the coagulating liquid from the coagulating liquid supply pipe 8 to the coagulating liquid water supply path 3 while adjusting the flow rate of the coagulating liquid. Thus, a controlled flow of the coagulating liquid is formed in the coagulating liquid water supply path 3 toward the outlet pipe 31 provided on the downstream side of the coagulating liquid water supply path 3. According to this configuration, the seaweed noodle manufacturing apparatus 30 can be made compact.

  The coagulating liquid supply channel 3 of the present invention is not limited to its shape as long as it can form a flow of coagulating liquid around the nozzle along the nozzle, and the method for introducing the coagulating liquid is not limited.

  Further, the direction in which the coagulation liquid flows is not limited to the horizontal direction described above, and may be a vertical direction. In this case, since the nozzles are arranged in parallel with the descending flow, they are arranged in the vertical direction.
