Description

[0001]
[Industrial application fields]
The present invention relates to a device for separating and removing raw seaweed foreign matter (dust, shrimp, thread, etc., the same shall apply hereinafter), and removing the foreign matter from a raw nori mixed solution (a mixture of raw nori and salt water at an appropriate concentration) via clearance. It is used when the leaves of fresh seaweed are passed in the direction of the exit of fresh seaweed out of fresh seaweed that has been separated and removed and has a stem portion filled with the clearance.
[0002]
[Prior art]
In this type of foreign matter separation and removal apparatus in the past, the outer peripheral edge of the annular frame plate portion is connected to the peripheral edge of the bottom portion of the mixed liquid tank, and a rotating plate is installed inside the annular frame plate portion. A clearance is formed between the rotating plate and the annular frame plate portion, and the rotating plate is rotated by an appropriate rotation driving means around the axis, and only fresh seaweed is allowed to pass through the clearance together with water and separated from foreign matter. It was. And if this clearance is clogged with fresh seaweed with stems, the clogged raw seaweed with stems is rotated together with the rotating plate and allowed to pass through the wide part of the clearance. (Actual registration 3053035).
[0003]
[Problems to be solved by the invention]
However, in such a conventional foreign matter separation / removal device, the raw seaweed with the stem part clogged (cleared) is removed by the suction force from below, but once clogged (clogged). When it occurs, the passage speed of the raw seaweed with this stem part becomes slower than that of normal raw seaweed, and as a result, the normal raw seaweed that comes later accumulates on the clogging and enlarges the clogging. There was a disadvantage that clogging could not be prevented.
[0004]
Furthermore, the conventional method has a wide clearance (0.2 to 0.3mm), so the foreign matter sorting performance is poor, and the raw nori with roots also passes through, so the roots are mixed into the dried nori and the quality of the product. Was worsening.
[0005]
An object of the present invention is to eliminate such inconvenience.
[0006]
[Means for Solving the Problems]
The foreign matter separation / removal device for raw seaweed according to the present invention uses the clearance formed by the annular frame plate portion and the rotating plate, and in the foreign matter separation / removal device for raw nori to separate foreign matter, the clearance configuration of the rotating plate A spiral groove or an inclined groove is provided in a part or / and a clearance constituting part of the annular frame plate portion, and the width of the spiral groove or the inclined groove is made substantially the same as the clearance to generate a screw pump action effect and clog the clearance. Because the raw seaweed leaves were passed through the raw seaweed towards the exit of the raw seaweed among the raw seaweed with stems, when the leaves of the raw seaweed clogged with clearance entered the spiral groove or inclined groove, The clearance is passed through the clearance by the screw pump action by the spiral groove or the inclined surface of the inclined groove and discharged to the outlet side of the raw laver.
[0007]
In this case, when the spiral groove or the inclined groove is provided in the clearance constituting portion of the rotating plate and the clearance constituting portion of the annular frame plate portion, the above-described effects can be exhibited synergistically.
[0008]
The foreign matter separation / removal device for fresh seaweed according to the present invention includes a rotating plate installed inside the annular frame plate portion, and a clearance is formed between the rotating plate and the annular frame plate portion. In the fresh seaweed foreign matter separation and removal device which can be rotated by a rotation driving means as appropriate around an axis, a required number of inclined grooves are formed on the inner peripheral edge of the annular frame plate part and / or the outer peripheral surface of the rotary plate. The width of the inclined groove is made substantially the same as the clearance, and a screw pump action effect is generated to pass the leaf part of the raw seaweed toward the exit of the raw seaweed out of the raw seaweed with the stem part clogged with the clearance. Therefore, when the leaf portion of fresh seaweed clogged with clearance enters the spiral groove or inclined groove, the rotation plate rotates to the appropriate rotation driving means, so that The flop action and effect are those discharged to the outlet side of the raw laver through the clearance.
[0009]
In this case, when the required number of inclined grooves are provided on the inner peripheral edge of the annular frame plate portion and the outer peripheral surface of the rotating plate, the above effects can be exhibited synergistically.

The first rotating shaft 24 or the second rotating shaft 34 is fitted in the shaft holes 262 and 362, respectively. Therefore, these rotary plates 26 and 36 can be rotated by the rotational drive of the first motor 21 or the second motor 31, respectively.
[0020]
In FIG. 4, 269 is an inclined groove formed on the outer peripheral surface of the first rotary plate 26, and 369 is an inclined groove formed on the outer peripheral surface of the second rotary plate 36. The clearance C in the inclined grooves 269 and 369 is wider than other portions. However, the width of this portion is as narrow as about 0.2 mm, and it is for passing a thing clogged by the screw pump action.
[0021]
In FIG. 1, reference numeral 53 denotes a raw material supply pipe, which is installed at the upper end edge of the mixed liquid tank 10. Via this raw material supply pipe 53, a raw material liquid (a mixture of raw nori, water and foreign matter) is supplied into the mixed liquid tank 10. Although not shown, a water supply pipe is also installed at the upper edge of the mixed liquid tank 10. Reference numeral 54 denotes a liquid level upper limit level sensor, and reference numeral 55 denotes the lower limit level sensor, which are respectively installed in the liquid mixture tank 10. This liquid level upper limit level sensor 54 controls the supply of the mixed liquid and water into the mixed liquid tank 10 (stops the supply of the mixed liquid and water when the mixed liquid reaches a predetermined amount in the tank 10).
[0022]
An outflow pipe 52 is installed below the first pot 112 and the second pot 113 in the bottom plate 11, and sends the raw laver mixed liquid from which foreign matters are removed to the batch water tank B through a suction pump.
[0023]
In FIG. 2, 51 is a discharge pipe installed on the bottom plate 11 for discharging the removed foreign matter out of the mixed liquid tank 10.
[0024]
Next, the operation of the foreign matter separation and removal apparatus D will be described.
[0025]
First, a raw nori mixed solution (a mixture of raw nori including foreign matters and salt water in an appropriate concentration) is supplied into the mixed solution tank 10 through the raw material supply pipe 53. Then, the motors 21 and 31 are driven to rotate the first rotating plate 26 and the second rotating plate 36 (in the directions of arrows in FIGS. 2 and 4). Then, only raw nori smaller than the clearance C passes through the clearance C together with water and is sucked downward. At this time, since the first rotating plate 26 and the second rotating plate 36 are rotating, the fresh seaweed is hardly clogged in the clearance C.
[0026]
In rare cases, the narrow portion of the clearance C (the portion of the clearance C where the inclined grooves 232, 332, 269, and 369 do not exist) may be clogged with so-called raw laver with a stem. In this case, the clogged fresh seaweed is held in that place, but the rotating plates 26, 36 rotate to the part where the inclined grooves 269, 369 provided in the rotating plates 26, 36 are clogged, and the leaf parts are rotated by the screw pump action. Only in the direction of passing through the clearance C.
[0027]
In the above embodiment, the first annular frame plate 23, the second annular frame plate 33, the inclined groove 269 of the first rotating plate 26, and the inclined groove 369 are formed in the second rotating plate 36. The inclined grooves 232 and 332 can be provided only on the second annular frame plate 33, or the inclined grooves 269 and 369 can be provided only on the first rotating plate 26 and the second rotating plate 36.
[0028]
Further, the “inclined groove” in the present invention includes a “spiral groove” and the like.
[0029]
