Description

  The present invention is a mixture of raw seaweed and seawater obtained by cutting raw seaweed (raw seaweed) collected from the sea such as a seaweed farm and mixing with seawater (hereinafter referred to as “raw seaweed mixed liquid”). BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a raw seaweed foreign matter separating apparatus and a method for separating and removing foreign matter from raw seaweed for the purpose of separating foreign matter mixed in the seaweed.

  In particular, the fresh seaweed mixture liquid is forced to pass through a narrow gap, and foreign matter separation / removal processing is performed with a raw seaweed foreign matter separation device that separates foreign matter of a size that cannot pass through the gap from the raw seaweed mixture liquid. When the treatment is interrupted and the separated / removed foreign matter is discarded outside the fresh seaweed foreign matter separation device, the amount of untreated fresh seaweed that is discarded along with the foreign matter is reduced, thereby nori culture The present invention relates to a system that can contribute to improving the production amount and the production efficiency of dry seaweed by using as much as possible the seaweed raw algae (raw seaweed) collected from the sea such as the field.

  Dried seaweed for food use is collected from the seaweed raw algae (raw seaweed) cultivated with a net in the sea, cut, washed, dehydrated, etc., then dried to a predetermined shape and size, etc. It is manufactured by.

  In the above-mentioned case, foreign matter (for example, dust such as sawdust, nets, shrimp insects, synthetic resin pieces, crustacean fragments, seaweeds other than seaweed, etc.) adhere to the cultured seaweed raw algae (raw nori) Therefore, there is a possibility that such a foreign substance may be mixed into the dry nori simply by cutting, washing, dehydrating, etc. the original seaweed (raw nori).

  Even if a small amount of foreign matter is mixed in the dried seaweed, its value as a product decreases, so in the processing process of raw seaweed (seaweed raw algae) that cuts, cleans, dehydrates, etc. However, since the raw nori (the nori seaweed) and the foreign object are often attached (or entangled), cutting the raw nori (the nori seaweed), It is difficult to more reliably separate and remove foreign matters only by washing, dehydration, and the like.

  Therefore, the raw nori mixed solution that is a mixture of raw nori (seaweed algae) and seawater introduced into the foreign matter separation tank is forced to pass through a gap having a narrow interval of about 0.1 mm to 0.2 mm. A fresh seaweed foreign matter separation / removal apparatus / method for separating foreign matter having a size that cannot pass through the gap from the fresh seaweed mixture is widely used. For example, a ring is arranged on the inner peripheral edge of the circular hole formed in the bottom surface of the foreign substance separation tank, and a rotating disk whose outer diameter is slightly smaller than the inner peripheral diameter of the ring is arranged inside the ring, so that the rotating disk is fast While being rotated at the same time, the raw nori mixed solution is forcibly sucked and passed through a narrow gap of about 0.1 mm to 0.2 mm formed between the outer periphery of the rotating disk and the inner periphery of the ring. In addition, there has been proposed a fresh seaweed foreign matter separation device that separates and removes foreign matter having a size that cannot pass through the gap from the raw nori mixed solution that passes through the gap.

  In the conventional raw laver foreign matter separating apparatus / method, the raw laver mixed liquid is forcibly sucked and passed through a narrow gap from a foreign matter separation tank containing the raw laver mixed liquid so that it cannot pass through the gap. Since foreign matter is separated and removed, if the foreign matter separation / removal process is performed for a predetermined time, the process is temporarily stopped, water is poured into the foreign matter separation tank, and the foreign matter remaining in the foreign matter separation tank. Is discarded outside the foreign matter separation tank (hereinafter referred to as “dispensing”), and then the fresh laver mixture is again introduced into the foreign matter separation tank, and the foreign matter is forcibly sucked through the gap again. Separation / removal processing is performed.

  For this reason, at the time of paying out, a waste pipe that constitutes a flow path in which water, foreign matter, and the like are discarded outside the foreign matter separation tank is connected to the foreign matter separation tank.

  The waste pipe is provided with a valve body (for example, a discharge valve) that opens and closes, and a foreign matter separation tank is subjected to a foreign matter separation process for a predetermined time (eg, about 10 to 20 minutes) by a timer or the like. When the raw nori mixed liquid is exhausted, the forced suction through the gap is interrupted, while the water for dispensing is supplied to the foreign matter separation tank and the valve element ( The discharge valve) is opened, and the separated and removed foreign matter and water and the water are discarded outside the foreign matter separation tank through the disposal pipe.

  In such a conventional raw seaweed foreign matter separation / removal device, the valve body (dispensing valve) of the waste pipe is closed while the foreign laver mixture is put into the foreign matter separation tank and the foreign matter separation / removal processing is performed. Has been. Therefore, while the fresh laver mixture is put into the foreign matter separation tank and the foreign matter separation / removal process is performed, the foreign matter separation / removal is performed on the upstream side (foreign matter separation tank side) of the valve body (dispensing valve) of the disposal pipe. There is a raw laver mixture to be processed.

  As described above, when the dispensing process is performed every predetermined time (for example, about 10 to 20 minutes), the foreign matter separation existing on the upstream side (foreign matter separation tank side) from the valve body of the disposal pipe. The raw laver mixed liquid that has not been removed is also discarded outside the foreign matter separation tank.

  The disposal pipe connected to the foreign matter separation tank has an inner diameter of about 50 mm and the length to the valve body is only about 500 mm, but at the time of dispensing performed every predetermined time (for example, about 10 to 20 minutes) In addition, when the untreated raw laver that has not yet been subjected to the foreign matter separation / removal process stored here is discarded for each payout process, the whole process of foreign matter separation / removal process of raw laver that is performed in one day The amount of unprocessed raw seaweed that is discarded in the sea is not negligible.

  If the foreign matter separation / removal process can be used for dry seaweed production without discarding the untreated raw seaweed that has not yet been subjected to the foreign matter separation / removal process, it has been collected from the sea such as a laver farm. Effective use of raw seaweed can be effectively utilized to increase the production of dry seaweed and improve production efficiency.

  Therefore, the present invention forcibly feeds the raw nori mixture into the foreign matter separation tank through a gap provided in the foreign matter separation tank into which the raw nori mixture, which is a mixture of raw nori and seawater, is charged and stored. Foreign matter separated and removed from the raw nori mixture when performing the separation / removal process of the raw nori foreign matter that separates and removes the foreign matter that cannot pass through the gap by passing it to the outside. Reduce the amount of untreated raw seaweed that has not been separated and removed from the outside of the separation tank, and this allows the seaweed algae (raw seaweed) collected from the sea such as laver farms to be collected. The purpose is to provide a system that can be used as much as possible to contribute to improving dry seaweed production and production efficiency.

  The raw nori mixture is forcibly passed outside the foreign matter separation tank through a gap provided in the foreign matter separation tank into which the raw nori mixed liquid, which is a mixed liquid of raw nori and seawater, is charged and stored. By this, it is a system attached to the raw laver foreign matter separating apparatus for performing the raw laver foreign matter separating / removing process for separating and removing the foreign matter having a size that cannot pass through the gap from the raw laver mixed liquid.

The on-off valve is configured with respect to a disposal pipe that constitutes a flow path in which the foreign matter remaining in the foreign matter separation tank is discarded from the foreign matter separation tank to the outside of the foreign matter separation tank. Than the water supply pipe connected on the foreign matter separation tank side,
Untreated raw laver waste comprising pump means for supplying water into the foreign matter separation tank via the water supply pipe and the disposal pipe while the raw seaweed foreign matter separation / removal process is performed It is a quantity reduction system.

  According to the present invention, the raw nori mixed liquid is forcibly forced through the gap provided in the foreign matter separation tank into which the raw nori mixed liquid, which is a mixed liquid of raw nori and seawater, is charged and stored. Foreign matter separated and removed from the raw nori mixture when performing the separation / removal process of the raw nori foreign matter that separates and removes the foreign matter that cannot pass through the gap by passing it to the outside. Reduce the amount of untreated raw seaweed that has not been separated and removed from the outside of the separation tank, and this allows the seaweed algae (raw seaweed) collected from the sea such as laver farms to be collected. It can be used as much as possible to improve dry laver production and production efficiency.

The schematic block diagram which abbreviate | omitted one part explaining the system configuration | structure of this invention.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 illustrates an example of the entire configuration for explaining an example of a raw seaweed foreign matter separation / removal apparatus in which the system of the present invention is employed.

  The raw seaweed foreign matter separating apparatus 1 illustrated in FIG. 1 rotates a raw laver mixed liquid that is a mixed liquid of raw seaweed (original seaweed of seaweed) and water (for example, seawater) charged into the foreign matter separation tank 2. In addition, by forcibly sucking the raw nori mixed solution through the annular gap 3 in a plan view, foreign substances that cannot pass through the gap 3 (for example, sawdust etc.) Waste, nets, shrimp insects, synthetic resin pieces, crustacean fragments, seaweeds other than seaweed, etc.).

  As illustrated in FIG. 2, a circular hole 4 is formed in the bottom surface 10 a of the foreign matter separation tank 2 including the partition wall 8, the partition wall 46, and the outer wall 45, as illustrated in FIG. Rotating disks 5a, 5b, 5c and 5d (which may be collectively referred to as “rotating disk 5” in the present specification and drawings) rotated by a driven rotating shaft 6 are shown in FIGS. As shown in the figure, it is loosely fitted inside the circular hole 4 so as to be freely rotatable.

  A metal ring 10b is attached to the inner peripheral edge of a circular hole formed in the bottom surface 10a of the foreign matter separation tank 2 by screwing or the like.

  The gap 3 is formed between the inner peripheral wall of the circular hole 4, that is, the inner peripheral wall of the ring 10 b and the outer peripheral wall of the rotating disk 5 facing this.

  The size (size) and interval of the gap 3 determined by the interval between the inner peripheral wall of the circular hole 4, that is, the inner peripheral wall of the ring 10 b and the outer peripheral wall of the rotating disk 5 are, for example, 0.1 mm to 0 mm. .2 mm.

  Suction chambers 7 are respectively provided below the circular holes, and suction pumps 50 are connected to the suction chambers 7 through suction pipes 51a, 51b, 51c, 51d, and 51e, respectively.

  After putting the raw nori mixture into the foreign matter separation tank 2, the rotating plates 5a, 5b, 5c, and 5d are rotated by the motor 49 as indicated by arrows 30a, 30b, 30c, and 30d, and the rotating disks 5a, 5b, and 5c are rotated. When suction by the suction pump 50 is started while rotating the raw laver mixed liquid on 5d in the same manner, the mixed liquid is forcibly sucked into the suction chamber 7 through the gap 3, and the suction pipe It is put into the storage tank 52 as indicated by arrows 37e and 38 through 51a, 51b, 51c, 51d and 51e.

  The raw nori mixed liquid is forced to pass through the gap 3 while receiving the rotational force in this manner, so that foreign substances having a size that cannot pass through the gap 3 are separated and removed from the raw nori mixed liquid passing through the gap 3. It remains in the foreign matter separation tank 2.

  This process will be described in more detail as follows.

  The raw laver mixed liquid fed from the pretreatment step as shown by the arrow 33 (FIG. 1) is sent by the pump 41 to the mincing machine 43 through the feed pipe 42 as shown by the arrow 34. The mincing machine 43 is provided with a rotary cutting blade so as to be orthogonal to the flow of the raw nori mixed liquid moving in the feed pipe 42, and the raw nori is cut finely by passing the mixed liquid therethrough. For example, raw seaweed (original seaweed) having a length of about 50 mm to 300 mm is cut into a length of about 20 mm to 50 mm.

  The raw laver mixture liquid thus finely cut is subsequently transferred through the feed pipe 44 as indicated by an arrow 35 and is introduced into the foreign matter separation tank 2 as indicated by an arrow 36.

  The partition wall 8 partitioning the foreign matter separation tank 2 is made of punching metal, and has a large number of minute-diameter through holes 8a.

  Although the size of the small-diameter through-holes 8a formed in the partition wall 8 is larger than the size (size) / interval of the gap 3 described above, forced suction by the suction pump 50 described above is performed. Otherwise, the raw seaweed that is subjected to foreign matter separation / removal processing is sized so that it cannot pass through.

  Foreign matter (for example, dust such as sawdust, nets, shrimp insects, synthetic resin pieces, crustacean fragments, seaweeds other than seaweed, etc.) in the raw laver mixed liquid introduced into the foreign matter separation tank 2, By passing through the mincing machine 43, the foreign material is cut more finely than the minute diameter of the through-holes 8a formed in the partition wall 8 and can pass through the through-holes 8a without being subjected to forced suction. Enters the inside of the outer wall 45 from the through-hole 8a through the partition wall 46 and flows out to the disposal pipe 47a together with water (seawater).

  On the other hand, since forced suction is not performed, fresh seaweed that is subject to foreign matter separation / removal processing through the gap 3 is interposed between the partition wall 8 and the partition wall 46 through the through holes 8a of the partition wall 8. There is almost no inflow.

  For the raw laver mixed liquid staying in the foreign matter separation tank 2, the motor 49 is driven and the rotating shaft 6 is rotated at an appropriate rotational speed, for example, 200 rpm to 600 rpm, so that the rotating plate 5 is rotated. It rotates as indicated by an arrow 30a and a rotational force is applied.

  At the same time, when the suction pump 50 is activated to start suction, the raw laver mixed liquid that is rotating in the direction of the arrow 30 as the rotating plate 5 rotates is moved in the direction of the suction chamber 7 through the gap 3. It is forcibly sucked.

  Thereby, the raw laver mixed liquid in the foreign matter separation tank 2 is also forcibly sucked into the gap 3 and sucked into the suction chamber 7, and further, through the suction pipes 51a, 51b, 51c, 51d, 51e, Suction is performed as indicated by an arrow 37e, and is introduced into the storage tank 52 as indicated by an arrow 38.

  Since it is forcibly sucked through the gap 3 having a size (size) and interval of 0.1 mm to 0.2 mm, fine foreign matters (for example, dust such as sawdust, mites, shrimp insects, synthetic resin pieces, shells) Debris, seaweeds other than laver, etc.) cannot pass through the gap 3 and are separated and removed from the raw laver mixture.

  The raw nori mixed liquid that has been introduced into the storage tank 52 as indicated by the arrow 38 and separated and removed by the foreign matter is slowly rotated as indicated by the arrow 61 in the storage tank 52 by the rotation of the stirring blades 53, while being stored in the storage tank 52. And then transferred to the next process by suction or the like as indicated by an arrow 62.

  On the other hand, if a large amount of the separated foreign matter remains in the foreign matter separation tank 2 by continuing the foreign matter separation process for a predetermined time, the payout process is performed.

  In the payout processing step, the introduction of the raw laver mixture into the foreign matter separation tank 2 is stopped, and then the rotation of the rotating disk 5 and the suction by the suction pump 50 are stopped. Then, a clean cleaning liquid (for example, water or seawater) is introduced into the foreign matter separation tank 2 as indicated by an arrow 63, and foreign matters remaining in the foreign matter separation tank 2 are formed on the bottom surface 10a of the foreign matter separation tank 2. The foreign matter discharge port 9 (FIG. 2) and the disposal pipe 48 are discarded outside the foreign matter separation tank 2.

  In this payout processing step, clean washing water (for example, water or seawater) is also poured inside the outer wall 45 as indicated by an arrow 64, and between the partition wall 8 and the partition wall 46, the partition wall 46 and the outer wall 45. Since the disposal pipes 47 a and 47 b connected between the two are connected to the disposal pipe 48, they exist between the partition wall 8 and the partition wall 46 and between the partition wall 46 and the outer wall 45. Also, foreign matter or the like that has passed through the small-diameter through-hole 8a of the partition wall 8 is discarded outside the foreign matter separation tank 2 as indicated by an arrow 65 through the disposal pipes 47a and 47b.

  The disposal pipe 48 is provided with a dispensing valve (opening / closing valve body) 70. The valve body 70 is closed while the foreign matter separation process is performed, and the valve body 70 is closed simultaneously with the start of the dispensing process. Opened and discarded to the outside of the foreign matter separation tank 2 via the disposal pipes 48, 47a, 47b.

  This payout processing step is usually performed about once every 10 to 20 minutes, although it varies depending on the degree of contamination of the raw laver mixture. For example, it is possible to set a timer every 10 minutes and automatically insert a payout process step at intervals of 10 minutes between successive foreign matter separation process steps.

  When the payout processing step is finished, the washing water is turned on, the payout valve (opening / closing valve body) 70 is closed, and the pouring of the raw laver mixture into the foreign matter separation tank 2 is resumed. The rotation of the rotating disk 5 and the suction by the suction pump 50 are started, and foreign matter separation processing is performed.

  In the system of the present invention, the distal end side of the water supply pipe 71 is connected to the upstream side (foreign matter separation tank 2 side) of the discharge valve (opening / closing valve body) 70 of the disposal pipe 48. The proximal end side of the water supply pipe 71 is connected to pump means 74 (FIG. 3) such as a submersible pump.

The water supply pipe 71 is provided with a valve body 72 for opening and closing, and the valve body 72 is opened while the raw seaweed foreign matter separation / removal process is being performed. When the payout process is performed, the valve body 72 is closed. While the fresh seaweed foreign matter separation / removal process is being performed and the valve body 72 is open, as described above, the tip of the disposal pipe 48 is closed. Since the discharge valve (opening / closing valve body) 70 provided on the side (outlet side) is closed, the water (for example, seawater) fed from the pump means 74 is indicated by an arrow 73. Then, the water is supplied from the water supply pipe 71 to the disposal pipe 48 and is then supplied into the foreign matter separation tank 2 through the disposal pipe 48 as indicated by an arrow 73a.

  At this time, since the disposal pipes 47a and 47b connected between the partition wall 8 and the partition wall 46 and between the partition wall 46 and the outer wall 45 are connected to the disposal pipe 48, the partition wall 8 and the partition wall are separated. Also between the wall 46 and between the partition wall 46 and the outer wall 45, the water has been fed through the waste pipe 48 and the waste pipes 47 a and 47 b through the pump means 74 and the water supply pipe 71. Water is supplied.

  Thus, while the raw seaweed foreign matter separation / removal process is being performed, the water (for example, seawater) fed from the pump means is always in the foreign matter separation tank 2 via the disposal pipes 48, 47a, 47b. It will be in the state being supplied to. Therefore, while the foreign matter separation / removal process is being performed, untreated raw laver that has not been subjected to the foreign matter separation / removal process does not flow into the disposal pipes 48, 47a, 47b.

  As a result, the foreign matter separation / removal process is stopped, and when the dispensing process is started as described above, the unprocessed raw material that has flown into the disposal pipe 48 and has not yet been subjected to the substance separation / removal process has been performed. There is no risk of nori being discarded.

  As a result, without discarding raw untreated seaweed that has not yet been subjected to foreign matter separation / removal processing, foreign matter separation / removal processing can be performed, foreign matter separation / removal processing can be performed and used for dry seaweed production, It is possible to increase the production efficiency of dry seaweed and improve production efficiency by making effective use of raw seaweed collected from the sea such as seaweed farms.

  Compared with the case where the system of the embodiment described above is applied to the raw seaweed foreign matter separation / removal apparatus 1 of the embodiment described above and illustrated using the seaweed original algae collected from the same seaweed farm. As a result, when compared with the working time of a normal day, the amount of dry seaweed produced by applying the system of this embodiment increased on average by 3 to 5% compared to the case where it was not applied. I was able to confirm.

  In addition, as shown by the arrow 65 (FIGS. 1 and 3), foreign matters and the like discarded outside the foreign matter separation tank 2 are separated from seawater and discarded, but the system of this embodiment is applied. In this case, the amount of disposal is reduced to about 1/3 of the conventional case where the system of this embodiment is not applied on average, and the labor required for disposal processing is greatly reduced.

  The size of the small-diameter through-holes 8a formed in the partition wall 8 is larger than the size (size) / interval of the gap 3 described above. It is not the size that can pass the raw seaweed to be removed. Therefore, while the foreign matter separation process is being performed, the untreated raw laver remains in the foreign matter separation tank 2 even if the foreign matter that passes through the small-diameter through holes 8a of the partition wall 8 is automatically discarded. It is rarely discarded outside.

  Therefore, the waste pipes 47 a and 47 b connected between the partition wall 8 and the partition wall 46 and between the partition wall 46 and the outer wall 45 are connected to the foreign matter discharge port 9 formed on the bottom surface 10 a of the foreign matter separation tank 2. It is also possible to adopt a configuration not connected to the disposal pipe 48 connected to (FIG. 2) and connected to the opening / closing operation by the discharge valve (opening / closing valve body) 70.

  In this way, while the raw seaweed foreign matter separation / removal process is being performed, the water (for example, seawater) fed from the pump means is always in the foreign matter separation tank 2 via the disposal pipe 48. While the supplied and foreign matter separation / removal process is being performed, untreated raw laver that has not yet been subjected to the foreign matter separation / removal process will not flow into the disposal pipe 48, While the raw seaweed foreign matter separation / removal process is being performed, it passes through the small-diameter through-holes 8a of the partition wall 8 and flows between the partition wall 8 and the partition wall 46 and between the partition wall 46 and the outer wall 45. The foreign matter having a size that can pass through the small-diameter through-holes 8a of the partition wall 8 is separated from the foreign matter separation tank 2 via the disposal pipes 47a and 47b while the fresh seaweed foreign matter is separated and removed. Will be disposed of outside.

  In this system, as the water to be fed into the waste pipe 48 via the water supply pipe 71 and the pump means, the sea water used in the whole raw laver foreign matter separation process is efficiently circulated and used. can do.

  For example, a concentration adjustment device for a mixed liquid for laminating laver may be used in the whole process of separating raw seaweed foreign matter, and minced seaweed algae and seawater are contained in a concentration adjustment tank and minced. The concentration of the mixed solution of seaweed raw algae and seawater is adjusted to an appropriate concentration. Water such as seawater used in the concentration adjusting device can be fed into the disposal pipe 48 via the water supply pipe 71 by pump means such as a submersible pump.

  Further, as described above, the seawater can be separated from the raw laver mixed liquid after the foreign matter separation and removal stored in the storage tank 52, and can be circulated and utilized.

  As mentioned above, although embodiment of this invention was described with reference to the accompanying drawing, this invention is not limited to this embodiment, In the technical range grasped | ascertained from description of a claim, it can change variously. is there.

  For example, in the above, the gap between the gaps of about 0.1 mm to 0.2 mm is forcibly made by using a raw laver mixed liquid that is a mixed liquid of raw nori (seaweed algae) and seawater introduced into the foreign matter separation tank. As a raw seaweed foreign matter separation device that separates foreign matter having a size that cannot pass through the gap from the raw laver mixture, a ring is arranged on the inner peripheral edge of the circular hole formed in the bottom surface of the foreign matter separation tank 2, and the outer diameter Is formed between the outer periphery of the rotating disk and the inner periphery of the ring while rotating the rotating disk at a high speed while arranging a rotating disk slightly smaller than the inner peripheral diameter of the ring. .Forcibly suck and pass the raw nori mixed liquid through a gap having a narrow interval of about 1 mm to 0.2 mm, and separate foreign substances having a size that cannot pass through the gap from the raw nori mixed liquid that passes through the gap. The apparatus for separating foreign matter from raw seaweed to be removed has been described. The raw seaweed foreign matter separation device is not limited to the one described above, and the raw seaweed mixed liquid is forced to pass through a narrow gap, and the foreign matter having a size that cannot pass through the gap is separated from the raw nori mixed liquid. The system of the present invention can be applied to the raw seaweed foreign matter separating apparatus having various structures and forms.
