  First, the foreign matter separation apparatus for laver mixture used in the rotation control method of the rotating part with the liquid level in the foreign matter separation apparatus for laver mixture according to the present invention as a reference value will be described.

  In the figure, reference numeral 1 denotes a laver mixed liquid tank. The laver mixed liquid tank 1 has a supply port 2 for introducing a laver mixed liquid, a foreign matter discharge port 3 for discharging foreign matter, a liquid level sensor 4 for fresh laver mixed liquid, and the like. Is provided. A sorting casing 5 is provided on the lower surface 1 c of the laver mixed liquid tank 1, and a sorting ring 50 is provided on the upper surface of the sorting casing 5. A tip portion 70 of the rotating portion 7 provided with an appropriate gap 6 is provided on the lower side 500 of the sorting ring 50. The flange 51 of the sorting casing 5 is mounted on the lower frame 1b of the laver mixed liquid tank 1 and is fixed by, for example, a set screw 100. The rotating portion 7 is fixed to a rotating shaft 9 penetrating a bearing 8 provided in the sorting casing 5. The rotary shaft 9 is rotated via a drive source (not shown). In the figure, reference numeral 10 denotes a raw laver suction port provided on the bottom surface of the sorting casing 5. The suction port 10 is provided with a tube (hose) for transporting fresh seaweed equipped with a pump (not shown). Further, a protrusion 71 for cleaning the gap 6 is provided on the outer periphery of the rotating portion 7. In the figure, A indicates a laver stirring / separation chamber, and 1a indicates an outer frame. The laver mixed liquid tank 1 is an example, and a similar mechanism is within the scope of the present invention.

  In the figure, reference numeral 11 denotes a cleaning water supply port serving as a cleaning water supply means facing the laver mixed liquid tank 1. Reference numeral 12 denotes a tube (hose) for conveying fresh seaweed equipped with a suction pump. Reference numeral 13 denotes a drain outlet for adjusting the liquid level, and reference numeral 14 denotes a hose provided at the foreign matter outlet 3.

  In the figure, reference numeral 16 denotes a slope provided on the inner surface 1d of the laver mixed liquid tank 1 so as to be detachably protruded or recessed, and extends from one side of the foreign matter discharge port 3 in the circumferential direction of the inner surface 1d. And a structure that reaches the other side of the foreign matter discharge port 3. This slope 16 is constructed so as to be inclined from one side to the other side, and it is intended to release the foreign matter of the laver mixed liquid from the gap 6 (induction in the separating direction). Further, by making a change in the swirling flow, the clogging of the gap 6 and the swirling of fresh seaweed are promoted. In addition, although it is the structure which sloped up the slope 16 toward the other side from one side, it is not limited to this, A stair-type (it is the same as the front view in FIG. 1), an uneven | corrugated type, a waveform type, There are examples such as a curved surface type, and there are configurations that give various changes to the swirling flow generated by the rotating unit 7, or there are horizontal examples that restrict the swirling flow generated by the rotating unit 7, etc. It is considered applicable.

  Next, the rotation control method of the rotating part using the liquid level in the foreign matter separator for laver mixed liquid according to the present invention as a reference value will be described.

  The laver mixture is sequentially introduced from the supply port 2 of the laver mixture tank 1 of the present invention. The introduced laver mixture (raw seaweed and / or foreign matter) is swirled in a substantially horizontal direction (turned and swirled in a substantially horizontal state) by the rotating unit 7. While being dispersed evenly throughout (not in the form of a lump), the laver is stirred and separated in the laver stirring / separating chamber A. And in the state which this nori mixed liquid has ensured the standard liquid level (standard liquid level), the said rotation part 7 and / or protrusion 71 are in the liquid (under the liquid level), and scattering of this nori mixed liquid Therefore, the rotation of the rotation unit 7 is set to the standard rotation number.

  Then, raw nori in the liquid is sucked using a gap 6 formed between the lower surface of the sorting ring 50 and the upper surface of the rotating portion 7 and is sent into the sorting casing 5. The fresh seaweed in the sorting casing 5 reaches the inner bottom surface of the sorting casing 5 and then is sent to a processing tank (not shown) via the suction port 10 and the hose 12.

  On the other hand, this laver mixed liquid deviates from the standard liquid level and becomes a low liquid level (generally, a liquid level (liquid level) slightly above the boss portion 72 of the rotating part 7) (the liquid level is low). In this state, the rotating part 7 and / or the protrusions 71 appear almost intermittently from the liquid surface, so that there is a risk of scattering of the laver mixed liquid. (Revolutions below standard speed). As a result, the speed of the swirling flow is reduced, so that scattering caused by the rotation of the rotating portion 7 and / or the protrusion 71 can be prevented.

  When the gap 6 becomes clogged with foreign matter, raw nori, etc., the gap 6 is opened, and the clogged raw nori is automatically sucked. The characteristics that can temporarily improve the clogging phenomenon by this processing method are as described in detail.

  The foreign matter remaining in the rotating part 7 described in detail is stopped from supplying the laver mixture, discharged from the laver mixture tank 1, and then discharged by the seawater or water supplied from the washing water supply means. Guided towards 3. Then, it is discharged out of the apparatus from the foreign matter discharge port 3 (pipe) by, for example, an automatic valve. The removal of foreign matter can be performed automatically and / or manually.

  The rotational speed of the rotating unit 7 is controlled based on the detection value of the liquid level sensor 4, but is visually checked by skilled intuition and / or nori (physical properties, amount of foreign matter mixed), amount, and productivity. It is possible to control based on the above. Further, the liquid level sensor 4 and visual observation are also used as necessary, and more accurate control and skillful intuition are used in combination.

  In the rotation control method that can control the number of rotations of the rotating part 7 of the nori mixed liquid tank in multiple stages, for example, ensuring the quality of raw nori and ensuring the number of rotations suitable for physical properties and / or reliable, simple and precise. There is a feature that can prevent scattering.
