As a result, the water in the upper dewatering sponge 51 can be sucked through the upper suction hole 534 of the upper plate 531 and the water can be efficiently removed from the upper dewatering sponge 51 .

The lower dewatering sponge 52 placed below the seaweed screen 2 is made of, for example, urethane, and is made of a porous and soft sponge-like material having a large number of pores inside, similar to the upper dewatering sponge 51. It is formed in a rectangular plate shape of substantially the same size or slightly larger size. As shown in FIGS. 2 and 3, the lower dewatering sponge 52 is detachably held by a lower plate 541 of the lower negative pressure suction means 54 with its plate surface facing up and down.

It is set narrowly, and (LX2)=2×(LX1).

In other words, the arrangement configuration of the through-holes 52a along the conveying direction X is such that the length of the lower dewatering sponge 52 in the conveying direction X is equally divided (6 divisions in FIG. Two rows of through-holes 52a are arranged in the horizontal direction Y on the side F and the rear end portion side R, and one row of through-holes 52a is arranged in the horizontal direction Y in the front-rear intermediate portion M. ing. In addition, in FIG. 3, the number of through holes 52a within the equal division width W is all set to be the same.

On the other hand, in the arrangement of the through holes 52a along the horizontal direction Y, the interval LY1 in the horizontal direction Y between the front end portion side F and the rear end portion side R is set wider than the interval LX1 in the transport direction X between the front and rear intermediate portions M. and (LY2)=1/2×(LY1).

The left and right end sides of the front end portion side F and the rear end portion side R of the through hole 52a are provided in substantially the same arrangement as the through holes in the front and rear intermediate portion M. As shown in FIG.

When the lower suction device 543 is operated, the lower space surrounded by the lower cover 542 is vacuum-sucked through the lower suction pipe 545 . As a result, the water in the lower dewatering sponge 52 is sucked through the lower suction hole 544 of the lower plate 541 , and the water can be removed from the lower dewatering sponge 52 efficiently.

Thus, water can be efficiently removed from the raw seaweed 21 in the dehydrating section 5 by the upper and lower dehydrating sponges 51 and 52 and the negative pressure suction means 53 and 54 of the dehydrating section 5 .

In this embodiment, the dewatering section 5 has a lower dewatering sponge 52 whose height position is fixed, while the upper dewatering sponge 51 is vertically movable by the press mechanism 55 . That is, the press mechanism 55 is an elevating means for elevating the upper dewatering sponge 51 . When the upper dewatering sponge 51 is lowered by the press mechanism 55, water is removed from the raw laver 21 by pressing the upper dehydrating sponge 51 and the lower dewatering sponge 52 against the raw laver 21 on the laver screen 2 from above and below. have it removed.

Further, after this press dehydration, when the upper dewatering sponge 51 is lifted by the press mechanism 55, the shape of the upper dewatering sponge 51 and the lower dewatering sponge 52 compressed and deformed by the press is restored. 52 further absorbs and removes the moisture remaining in the raw seaweed 21 .

In addition, the upper and lower dewatering sponges 51 and 52 are press-pressed, and the upper and lower dewatering sponges 51 and 52 are vacuum - sucked by the upper and lower suction devices 513 and 543, respectively. Backflow to the dewatering sponge 52 can be prevented.

As described above, in the laver manufacturing apparatus 1, the dehydrating section 5 includes a pair of dehydrating sponges 51 and 52 which are arranged vertically facing each other with the laver screen 2 interposed therebetween and can be separated from each other. Negative pressure suction force is applied to the dehydration sponges 51 and 52 through a plurality of suction holes 534 and 544 arranged side by side at predetermined intervals to remove moisture in the dehydration sponges 51 and 52. The dehydration sponges 51 and 52 are provided with a plurality of through holes 51a and 52a penetrating vertically, and the through holes 51a and 52a of the dehydration sponge and the Since the suction holes 534 and 544 of the negative pressure suction means are set at the same position in plan view, the dehydration effect in the dehydrating section is achieved by cooperation between the through holes of the dehydration sponge and the suction holes of the negative pressure suction means. can be further enhanced. In addition, there is an effect that the central portions of the dewatering sponges 51 and 52 are less likely to become dirty. Therefore, it is possible to realize a seaweed manufacturing apparatus which is easy to use with a long maintenance interval including cleaning and replacement of the dewatering sponge, and which can provide good seaweed without causing stains to adhere to the seaweed.
