Description

  This invention cuts a laver original algae (raw nori) collected from a laver farm and mixes it with water (for example, seawater), or a laver original algae (raw) Nori of raw seaweed for the purpose of separating the foreign matter mixed in the raw nori mixture from the raw nori mixture that is a mixture obtained by mixing seaweed and seawater (eg seawater) The present invention relates to a separation device.

  Dry seaweed for food use is manufactured by cutting, washing, dehydrating, etc. the original seaweed algae (raw seaweed) cultivated with a net in the sea, and then drying to a predetermined shape and size. Yes.

  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 foreign matter may be mixed into the dry seaweed only by cutting, washing, dehydrating, etc. the raw seaweed (raw seaweed).

  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. The foreign matter is separated and removed. However, since fresh seaweed (original seaweed algae) and foreign matter are often attached (or entangled), cutting, washing, dehydration, etc. of raw seaweed (original seaweed algae) alone will ensure foreign matter. It is difficult to separate and remove.

  Therefore, a method of separating and removing the above-mentioned foreign matter through a punching metal or the like, or a mixture of fresh seaweed (original seaweed of seaweed) and seawater charged in the foreign matter separation tank, with an interval of 0.1 mm The mixture of raw nori (seaweed algae) and seawater is forcibly sucked through a narrow clearance of about 0.2 mm, and the raw nori (seaweed algae) passing through the clearance and seawater A fresh seaweed foreign matter separating device for separating foreign matter that cannot pass through the clearance from a mixed solution has been proposed.

      While rotating the raw laver mixture liquid put into the foreign matter separation tank, the raw laver mixture liquid is forcibly sucked through the clearance, and the foreign matter that cannot pass through the clearance is separated from the raw laver mixture liquid that passes through the clearance. In a conventional fresh seaweed foreign matter separation device, if the clearance interval and size are made narrower for the purpose of reliably removing foreign matter, the fresh seaweed (original seaweed algae) tends to clog the clearance. Therefore, it has not been easy to satisfy both the purpose of reliably removing foreign matters and the purpose of removing foreign matters reliably by efficiently treating a larger amount of raw laver mixed liquid.

It has a predetermined circumferential length, and has a foreign substance separation tank bottom side recess having a predetermined depth from the upper plane of the portion surrounding the circular hole to the lower side.

      Alternatively, the rotating disk has a predetermined radial width radially inward from an outer peripheral edge of the upper end of the rotating disk and a predetermined circumferential length extending in the circumferential direction of the rotating disk. The rotating disk side recess has a predetermined depth from the upper plane of the rotating disk toward the lower side of the rotating disk.

      Or the part surrounding the said circular hole of the bottom face of the said foreign material separation tank is a structure provided with the said foreign material separation tank bottom face side recessed part, and the said rotating disc is equipped with the said rotating disk side recessed part.

      Further, the rotating disk is a rotating disk protrusion that protrudes in an upward direction from an upper plane of the rotating disk, and is a rotating disk that is an outer surface in the radial direction of the rotating disk protrusion. The protrusion outer wall surface has a rotating disk protrusion that does not protrude outward in the radial direction from the upper edge of the rotating disk in the vicinity of the upper edge of the rotating disk.

      The portion surrounding the circular hole on the bottom surface of the foreign matter separation tank is a fixing ring fixed at a position where the circular hole is formed on the bottom surface of the foreign matter separation tank, and the concave portion on the bottom side of the foreign matter separation tank Is a fixing ring side recess, and the fixing ring side recess has a predetermined radial width extending radially outward from an inner peripheral edge of the upper end of the fixing ring, and a predetermined circumference extending in the circumferential direction of the fixing ring. It is possible to make a structure having a predetermined length from the upper plane of the fixing ring to the lower side.

      By adopting such a structure, the purpose of surely removing foreign matters and the purpose of reliably removing foreign matters from a larger amount of fresh seaweed (original seaweed of seaweed) are compatible.

      According to the present invention, it is possible to provide a raw seaweed foreign matter separation apparatus that efficiently and reliably separates and removes foreign matter from a large amount of raw laver mixed liquid. That is, it is possible to provide a raw seaweed foreign matter separation apparatus that enables efficient and large-scale raw seaweed foreign matter separation processing.

      In the illustrated embodiment, the clearance 3 for separating the foreign matter having a size that cannot pass through the forcing of the raw nori mixture is provided on the bottom surface 100 of the foreign matter separation tank 2 that forms the circular hole 4. The fixing ring 10 is formed between the inner peripheral wall surface 20 and the outer peripheral wall surface 15 of the rotating disk 5 facing the inner peripheral wall surface 20.

      In the illustrated embodiment, the fixing ring 10 is attached to the bottom surface 100 at a location where the circular hole 4 is provided in the bottom surface 100 of the foreign matter separation tank 2. A circular hole 4 is formed inside.

      In the illustrated embodiment, as shown in FIG. 11 (a), the fixing ring 10 is attached to the bottom surface 100 of the foreign matter separation tank 2 by an embedded fixing means such as a flat screw and can be removed. It is fixed.

      FIG. 1 illustrates an example of the entire configuration of a raw seaweed processing apparatus provided with the raw seaweed foreign matter separating apparatus 1 of the present invention.

      As shown in FIG. 2, four circular holes 4 are provided on the bottom surface 100 of the foreign matter separation tank 2, and rotating disks 5 a, 5 b, 5 c, and 5 d are freely loosely fitted thereto, respectively. .

      The rotating disks 5 are respectively attached to the upper end side of the rotation center shaft 6 rotated by the motor 49.

      Under the four circular holes 4, suction chambers 7a, 7b, 7c, and 7d (collectively referred to as “suction chamber 7”) are provided, and the suction chambers 7a, 7b, 7c, A suction pump 50 is connected to 7d via suction pipes 51a, 51b, 51c, 51d, and 51e, respectively.

      After putting the raw nori mixed solution into the foreign matter separation tank 2, the rotating plate 5 is rotated by the motor 49 in the circumferential direction of the rotating disc 5 indicated by the arrow 30, and the raw nori mixed solution on the rotating disc 5 is the same. When the suction by the suction pump 50 is started while rotating and flowing as described above, the raw laver mixed liquid is sucked through the suction chambers 7a, 7b, 7c, and the clearance 3 as indicated by arrows 32 and 31 (FIG. 9B). 7d is forcibly sucked into the storage tank 52, and is further introduced into the storage tank 52 through the suction pipes 51a, 51b, 51c, 51d and 51e as indicated by arrows 37e and 38e.

      The raw nori mixed solution is forced to pass through the clearance 3 while receiving the rotational force in this way, so that the foreign matter that cannot pass through the clearance 3 is separated and removed from the raw nori mixed solution that passes through the clearance 3. It remains in the 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 mixed with the raw nori mixed liquid passes through here. Algae) is finely cut. 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 seaweed mixture, which is a mixture of raw seaweed (seaweed algae) and water (seawater) finely cut in this way, is subsequently transferred through the feed pipe 44 as shown by the arrow 35, and inside the foreign matter separation tank 2. As shown by the arrow 36.

      The partition wall 8 that partitions the foreign matter separation tank 2 is made of punching metal, and has a large number of minute-diameter through holes 8a. Therefore, foreign matter (for example, dust such as sawdust, nets, shrimp insects, synthetic resin pieces, crustacean fragments, seaweeds other than seaweed, etc.) contained in the raw laver mixture introduced into the foreign matter separation tank 2 Thus, the foreign matter cut finer than the small diameter of the through-holes 8a formed in the partition wall 8 by passing through the mincing machine 43 enters the outer tank 45 from the through-holes 8a together with water (seawater). Enters, flows over the partition wall 46, and flows out to the discharge pipe 47.

      On the other hand, the raw laver mixed liquid staying in the foreign matter separation tank 2 is rotated by driving the motor 49 and rotating the rotation center shaft 6 at an appropriate rotation speed, for example, 200 rpm to 600 rpm. The plate 5 rotates as indicated by an arrow 30 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 by the rotation of the rotating plate 5 is passed through the clearance 3 (see FIG. 9). (B) Forcibly sucked in the direction.

      As a result, the raw laver mixture in the foreign matter separation tank 2 is also forcibly sucked into the clearance 3 and sucked into the suction chamber 7 as indicated by an arrow 32 (FIG. 9B), and further, the suction pipe The air is sucked in as indicated by an arrow 37e through 51a to 51e, and charged into the storage tank 52 as indicated by an arrow 38.

      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 charging of the raw laver mixture into the foreign matter separation tank 2 is stopped. Then, the rotation of the rotary disk 5 and the suction by the suction pump 50 are stopped. Then, the foreign matter discharge port 9 (FIG. 2) provided on the bottom surface 10 a of the foreign matter separation tank 2 is opened, and a clean cleaning liquid is poured into the foreign matter separation tank 2 as indicated by an arrow 63 and remains in the foreign matter separation tank 2. The foreign matter that is being discharged is discharged from the foreign matter discharge port 9 to the outside.

      At this time, clean washing water is also poured into the outer tub 45 as indicated by an arrow 64, and foreign matter remaining in the outer tub 45 is discharged via the discharge pipes 47 and 48 as indicated by an arrow 65. .

      Although this washing | cleaning process changes with the grade of the stain | pollution | contamination of a raw nori mixture liquid, the objective can be achieved normally about once in 20 minutes-60 minutes. For example, the cleaning process can be automatically set at intervals of 30 minutes between successive foreign matter separation processing processes set every 30 minutes.

      When the washing process is completed, the washing water is finished, the foreign matter discharge port 9 is closed, the raw laver mixed liquid is put into the foreign matter separation tank 2 again, and the rotation disk 5 is subsequently rotated. Then, suction by the suction pump 50 is started and foreign matter separation processing is performed.

      In this embodiment, the inner peripheral wall surface 20 of the fixing ring 10 disposed on the bottom surface 100 of the foreign matter separation tank 2 that forms the circular hole 4 and the outer peripheral wall surface 15 of the rotating disk 5 that faces the inner peripheral wall surface 20. By setting the size (size) and interval (S) (FIG. 9B) of the clearance 3 formed between them to about 0.1 mm to 0.3 mm, foreign matter that cannot pass through this size ( For example, waste such as sawdust, nets, shrimp insects, synthetic resin pieces, crustacean fragments, seaweeds other than laver, etc. cannot pass through this clearance 3 and are separated and removed from the raw laver mixture. Is done.

      In the illustrated embodiment, the fixing ring 10 includes a fixing ring-side recess 91 corresponding to the foreign matter separation tank bottom-side recess (FIG. 6). The fixing ring-side recess 91 has a predetermined radial width W that extends radially outward from the inner peripheral edge 90 of the upper end of the fixing ring 10 and a predetermined circumferential length L that extends in the circumferential direction of the fixing ring 10. The concave portion has a predetermined depth D from the upper flat surface 92 of the fixing ring 10 toward the lower side of the fixing ring 10.

      In the illustrated embodiment, the rotating disk 5 includes a rotating disk side recess 71 (FIG. 3). The rotating disk-side recess 71 has a predetermined radial width w radially inward from the upper outer periphery 70 of the rotating disk 5 and a predetermined circumferential length l extending in the circumferential direction of the rotating disk 5. And a predetermined depth d from the upper flat surface 76 of the rotating disk 5 toward the lower side of the rotating disk 5.

      Both the fixing ring side recess 91 and the rotating disk side recess 71 rotate the raw laver mixed liquid in the foreign matter separation tank 2 by rotating the rotating disk 5 in the circumferential direction around the rotation center axis 6. The raw nori mixed liquid is directed downward of the clearance 3 through the clearance 3 formed between the inner peripheral wall surface 20 of the fixing ring 10 and the outer peripheral wall surface 15 of the rotating disk 5 facing the fixing ring 10. When the foreign matter that cannot pass through the clearance 3 is separated from the raw nori mixed solution that passes through the clearance 3, the clearance 3 is clogged with raw nori (original seaweed) and foreign matter. It is provided for the purpose of preventing the occurrence of a situation in which the rotational movement becomes difficult or the suction of the raw laver mixed liquid through the clearance 3 becomes difficult.

      That is, the fixing ring side recess 91 and the rotating disk side recess 71 both prevent the occurrence of the above-described situation, thereby reliably removing foreign matters from a larger amount of raw laver mixture, It is deployed for the purpose of making it possible to efficiently perform a foreign matter separation process on the raw nori mixture.

      As the rotating disk 5 rotates in the circumferential direction about the rotation center axis 6, the raw nori mixed liquid rotates in accordance with the rotation of the rotating disk 5 while moving toward the lower side of the clearance 3. At the time, both end edges 91a, 91b in the circumferential direction of the fixing ring side recess 91 and both end edges 71a, 71b in the circumferential direction of the rotating disk side recess 71 cut raw laver (original seaweed). To act as an edge. As a result, the clearance 3 is clogged with fresh seaweed (seaweed algae) and foreign matter, making it difficult to rotate the rotating disk 5, or making it difficult to suck the raw seaweed mixture through the clearance 3. Generation | occurrence | production is prevented and it becomes possible to perform a foreign material isolation | separation process efficiently with respect to a lot of raw nori mixed liquid, removing a foreign material reliably from a larger quantity of raw nori mixed liquid.

      Since the fixing ring side recess 91 is provided for the above-mentioned purpose, it is not only provided at one place as shown in FIG. 6, but also in the circumferential direction of the fixing ring 10 as shown in FIGS. A plurality of them can be provided with an interval of.

      In the embodiment illustrated in FIG. 7, the fixing ring side recesses 91 and 93 are provided at two locations to be targeted with respect to the center of the fixing ring 10. In the embodiment shown in FIG. 8, the fixing ring side recesses 91, 93, 94, and 95 are provided at four positions to be targeted with respect to the center of the fixing ring 10.

      Further, since the rotating disk side recess 71 is also provided for the above-mentioned purpose, it is not only provided at one place as shown in FIG. 3, but also as shown in FIGS. A plurality can be provided at predetermined intervals in the circumferential direction.

      In both the embodiment shown in FIG. 4 and the embodiment shown in FIG. 5, two rotating disk side recesses 71, 72 and rotating disk side recesses 73, 74 are formed with respect to the rotation center of the rotating disk 5. It is what.

      In the fixed ring side recess 91, the fixed ring side recess against the raw nori (raw seaweed) in the raw nori mixture that rotates in accordance with the rotation of the rotating disk 5 while facing the lower side of the clearance 3. Both end edges 91a and 91b in the circumferential direction 91 perform an edge function of cutting, but the fixing ring 10 itself is fixed. Therefore, both end edges 91a and 91b in the circumferential direction are formed by two fixing ring side recesses 91 and 93, respectively, as shown in FIG. 7, rather than being formed by only one fixing ring side recess 91 as shown in FIG. Furthermore, it is advantageous if the fixing ring side recesses 91, 93, 94, and 95 are respectively formed as shown in FIG.

      The predetermined circumferential length L extending in the circumferential direction of the fixing ring 10 can be set in consideration of the effective display of the edge function described above. Although depending on the size of the diameter of the fixing ring 10, a length L indicated by θ in FIG. 6 is set so that the central angle of both end edges 91 a and 91 b in the circumferential direction is in a range of 15 to 45 degrees. be able to.

      On the other hand, since the rotating disk 5 continues to rotate at 200 rpm to 600 rpm, the circle of the fixing ring side recess 91 described above has a predetermined circumferential length l extending in the circumferential direction of the rotating disk 5. There is no need to particularly examine the size considering the circumferential length L. What is necessary is just to have both end edges 71a and 71b in the circumferential direction of the rotating disk side concave portion 71 that fulfills the edge function. Therefore, as shown in FIG. 5, two rotating disk side recesses 73 and 74 having a size of l reaching the almost half of the circumference of the rotating disk 5 are formed. It is also possible to adopt other forms.

      In the case of the embodiment shown in FIG. 5, the portions indicated by reference numerals 75 a and 75 b other than the rotating disk side recesses 73 and 74 are flush with the upper plane 76 of the rotating disk 5. .

      A predetermined radial width W radially outward from the upper end inner peripheral edge 90 of the fixing ring 10 of the fixing ring side recess 91 and an inner side in the radial direction from the upper outer periphery 70 of the rotating disk 5 of the rotating disk side recess 71. As described above, the predetermined radial width w toward the fixing ring side recess 91 and the rotating disk side recess 71 is such that the clearance 3 is filled with fresh seaweed (seaweed algae) or foreign matter and the rotating disk 5 Since it is provided for the purpose of preventing the occurrence of such a situation that rotational movement becomes difficult, it is necessary that concaves are formed on the outer side and the inner side in the radial direction with the clearance 3 interposed therebetween. In any case, the size is about 1 mm to 5 mm.

      A predetermined depth D from the upper flat surface 92 of the fixing ring 10 to the lower side of the fixing ring 10 and a predetermined depth from the upper flat surface 76 of the rotating disc 5 to the lower side of the rotating disc 5. As described above, the fixing ring side recess 91 and the rotating disk side recess 71 are also clogged with fresh laver (original seaweed) and foreign matter in the clearance 3, and it becomes difficult to rotate the rotating disk 5. Therefore, it is necessary that a recess that performs an edge function is formed on the side of the entrance 3a (FIG. 11 (b)) of the clearance 3 because it is provided for the purpose of preventing the occurrence of a situation such as D is about 0.3 mm to 0.6 mm, and d is about 0.5 mm to 1.0 mm.

When the raw nori mixed solution is forcibly sucked in the downward direction of the clearance 3 through the clearance 3 to separate foreign matter that cannot pass through the clearance 3 from the raw nori mixed solution passing through the clearance 3, Occurrence of a situation in which it becomes difficult to rotate the rotating disk 5 due to clogging with raw laver (original seaweed of seaweed) or foreign matter, or suction of the raw laver mixture through the clearance 3 It is deployed for the purpose of preventing.

      Therefore, although the fixing ring 10 includes the fixing ring side recess 91, the upper flat surface 76 of the rotating disk 5 is flush with the upper end outer peripheral edge 70, or the upper flat surface 76 is the upper end outer peripheral edge 70 and A structure in which the rotating disk 5 is not provided with the rotating disk side recess 71, such as a protrusion that protrudes upward in the vicinity, and conversely, the rotating disk 5 is a rotating circle. Although the plate-side recess 71 is provided, the upper plane 92 of the fixing ring 10 is flush with the upper end inner peripheral edge 90, and the fixing ring 10 does not include the fixing ring-side recess 91. It can be prevented that the clearance 3 is clogged with fresh seaweed (original seaweed of seaweed) or foreign matter and the rotational movement of the rotating disk 5 becomes difficult.

      Further, as shown in FIG. 2, if the fixing ring 10 has a fixing ring side recess 91 and the rotating disk 5 has a rotating disk side recess 71, the fresh seaweed is provided in the clearance 3. (Nori seaweed) and foreign matter are clogged, making it difficult to rotate the rotating disk 5, or making it difficult to suck the raw nori mixture through the clearance 3 is more effectively prevented. It is more advantageous in removing foreign matters reliably from a larger amount of raw laver mixed liquid and performing an effective and large amount of raw laver separation processing.

The spring 84 determines the size (position) of the rotary disk 5 to move up and down as indicated by the double arrow 66 in accordance with the rotation of the gap adjusting rotary plate 82. For example, the spring 84 plays a role of determining the size (position) by which the rotating disk 5 is raised or lowered by 0.01 mm by rotating the gap adjusting rotating plate 82.

      Therefore, the rotating disk 5 is positioned by the spring 84 simply by rotating the gap adjusting rotating plate 82 in the 39a direction or 39b direction with the rotating disk 5 attached to the upper end side of the rotation center shaft 6. Ascending or descending gradually, the size of the interval (S) of the clearance 3 and the depth (L) of the clearance 3 and the rotation provided on the outer peripheral wall 15 of the rotating disk 5 can be easily performed. The distance (H) between the upper edge 70 of the disk-side tapered surface and the upper edge 90 of the fixed ring-side tapered surface of the inner peripheral wall 20 of the circular hole 4 can be finely adjusted to a desired size.
