The apparatus for removing foreign matter from nori includes the steps of washing algae and cutting and washing algae in the process of producing laver, and cutting and washing algae and dewatering laver, cutting and dewatering laver and maturing nori. It is used by incorporating it during the raw dehydration step, between the nori maturing raw dehydration step and the nori blending step, or between the nori blending step and the nori sheet forming step. In use, the seaweed mixed solution is supplied to the supply chamber 7 from the previous step by the supply hose 32. Part of the raw seaweed and part of the water of the seaweed mixture in the supply chamber 7 enter the separation chambers 16a and 16b through the separation holes 28,
Further, the water of the mixed liquid of seaweed and foreign matter such as small pieces of seaweed enter the foreign matter storage chamber 8 through the communication hole 6 a of the separation plate 6. Supply room 7
When the detection switch 90 detects that the liquid level inside has risen and has reached the upper limit, the supply of the seaweed mixed liquid by the supply means 31 is stopped by the signal thereof. On the other hand, the return unit 2
The water is supplied into the storage tank 80, and an appropriate amount of water, for example, about 80% is supplied into the storage tank 80 and the reflux tank 81, and the stirring means 84 is operated. Further, the drive motor 65 is driven to rotate the injection nozzle 59 along the periphery of the separation wall 27 in the arrow direction.

In this state, the suction pump 34 of the discharging means 33
The supply pumps 63 and 88 of the recirculation means 66 are operated, and the drive motor 44 for operating the rotation switching valve 35 is operated. Due to the operation of the suction pump 34, a large suction force acts on the discharge port 41 of the rotation switching valve 35, and the drive motor 4
By the operation of 4, the rotary valve body 42 rotates at a predetermined speed, and the two supply ports 38a and 38b are alternately communicated with the discharge port 41. Therefore, two supply ports 38a,
The maximum suction force of the suction pump 34 is constantly applied to 38b, so that the two separation chambers 16a and 16b of the foreign matter separator 15 are constantly operated.
The seaweed mixed solution in the inside is forcibly sucked intermittently for a predetermined time every predetermined time. When the seaweed mixed solution in the separation chambers 16a and 16b is forcibly sucked intermittently, the seaweed mixed solution in the supply chamber 7 is forcibly sucked from the separation hole 28 into the separation chambers 16a and 16b for a predetermined time and then for a predetermined time. To stop. Separation chamber 16
The time during which the suction force acts on a and 16b can be arbitrarily adjusted by the rotation speed of the rotary valve body 42 by the drive motor 44, but is set to, for example, 1 second or 2 seconds, and the time during which the suction force action is stopped is also 1 Set to seconds or 2 seconds.

The seaweed mixed liquid sucked by the suction pump 34 is supplied to the injection pipe 83 of the reflux unit 2 through the connection hose 54, and is supplied into the storage tank 80 from the injection hole 83a of the injection pipe 83. Since the seaweed mixed liquid sprayed from the spray hole 83a contacts the partition wall 82, the communication hole 8
The clogging of 2a with raw seaweed is eliminated. When the supply pump 63 of the reflux means 66 is operated, the auxiliary reflux tank 69
The water inside is sucked and supplied from the rotary shaft 58 into each of the jet nozzles 59, and the water is jetted from the jet holes 59a of the jet nozzle 59. The water sprayed from the spray holes 59 a is continuously sprayed over the entire circumference of the separation wall 27, and the seaweed mixed liquid in the supply chamber 7 existing near the periphery of the separation wall 27 is sprayed on the separation wall 27. The seaweed mixed solution is positively sent to the separation hole 28. When the supply pump 88 is operated, the water in the reflux tank 81 is supplied to the auxiliary reflux tank 69 via the supply hose 89.

Since the separation hole 28 is formed in an elongated shape having a hole width slightly larger than the thickness of raw seaweed,
Raw seaweed of the seaweed mixture is separated from the separation hole 28 together with water in the separation chamber 1
Foreign matter such as shrimps and mussels having a size larger than the hole width of the separation hole 28 is retained by the edge of the separation hole 28 and left in the supply chamber 7. Since the width of the separation hole 28 is formed to be slightly larger than the thickness of the raw seaweed, for example, about 0.3 mm, the seaweed mixed liquid in the separation chamber 16 has a width of, for example, about 0.3 mm or more. There is no foreign material. The seaweed mixed solution in the supply chamber 7 is separated from the separation hole 28 in the separation chamber 1
A phenomenon in which the raw seaweed of the seaweed mixed liquid adheres to the outer periphery of the seaweed foreign matter separator 15 and blocks the separation hole 28 by positively sucking into the seaweed 6a, 16b is shown.
Since water is continuously sprayed from the spray hole 59a of 9 over the entire circumference of the separation wall 27, and the suction force acting on the separation chambers 16a, 16b is intermittently stopped by the rotation switching valve 35, The raw seaweed and the foreign matter adsorbed on the separation wall 27 are peeled off by water jet from the jet nozzle 59 when the suction force does not act, and the clogging of the separation hole 28 is efficiently cleaned to improve the inflow of raw seaweed. This greatly improves the ability to remove laver foreign matter per unit time. Further, when the suction pump 34 is continuously operated, the two separation chambers 16 are
Since the suction force acting on a and 16b is selectively switched by the rotation switching valve 35, a large suction force by the suction pump 34 always acts on each separation chamber 16 intermittently, and as a result, the seaweed mixed liquid is obtained. Can be efficiently sucked into the separation chambers 16a and 16b with a large force, and the small foreign matter separation tank 15
Therefore, a large foreign matter removing ability can be exhibited.

As described above, the seaweed mixed liquid is supplied to the storage tank 80 by the discharge means 33 and the storage tank 8 is supplied.
Since the water in the reflux tank 81 communicating with 0 is refluxed by the reflux means 66, the concentration of the seaweed mixed solution in the storage tank 80 is increased in a short time. In addition, the amount supplied to the storage tank 80 by the discharge means 33 is changed to the reflux tank 81 by the reflux means 66.
The amount of the seaweed mixed liquid in the storage tank 80 can be increased by slightly increasing the amount discharged from the storage tank 80. Detection switch 9 that the liquid level in the storage tank 80 has reached the upper limit
When 3 is detected, the operation of the suction pump 34 of the discharging means 33 is stopped. When the concentration of the laver mixed solution in the storage tank 80 reaches a desired concentration, the feed pump 91A of the feeding means 90 is operated to discharge the laver mixed solution to the next step. Since the foreign matter is removed from the seaweed mixture, the quality of the seaweed product after papermaking can be improved. When the detection switch 94 detects that the mixture of seaweed in the storage tank 80 has decreased due to the supply by the supply unit 90 and the lower limit has been reached, the suction pump 34 is operated.

On the other hand, when the detection switch 92 detects that the amount of the seaweed mixed liquid in the supply chamber 7 has become low and has reached the lower limit, the supply pump of the supply means 31 is operated again. In addition, the discharge amount from the supply chamber 7 by the discharge means 33 is determined by the reflux means 6
6, the foreign matter can be removed efficiently by making the amount of discharge by the discharge means 33 substantially equal to the sum of the amount of supply by the supply means 31 and the amount of reflux by the reflux means 66. Further, it is preferable that the recirculation means 66 is always operated and the injection device 56 is continuously operated. Bubbles and light dust floating on the water in the foreign matter storage chamber 8 flow over the overflow plate 78 of the communication window 74 into the foreign matter separation passage 73 and flow on the inclined separation wall 72 when the liquid level approaches the upper limit. The water of the seaweed mixed liquid flowing on the inclined separating wall 72 is collected in the auxiliary reflux tank 69 through the separating net 75 of the opening 72a, and bubbles and dust flowing on the separating net 75 are discharged from the discharge hose 76.

It is left outside and removed. In this case, when the rotating shaft 105 is rotated, the separation hole 28 facing the separation chamber 16af is formed.
f will change sequentially. As a result, the new separation hole 28f on which the seaweed is not adsorbed faces the separation chamber 16af, so that the seaweed can be efficiently sucked from the separation hole 28f and the foreign matter separation capability can be enhanced. In the present application, the inside of the hollow container may be divided into three or more chambers.
