Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laver producing apparatus for producing dry laver by adhering raw laver to a laver cage in a sheet form and drying it, and a method for cleaning a water absorbing member in the laver producing apparatus.

[0002]

2. Description of the Related Art A seaweed production apparatus is used to make a seaweed cage by transporting a seaweed cage by a conveyor, and a dewatering section for dewatering the raw seaweed that has been dried, and a dewatering section for dewatering the raw seaweed. It consists of a drying room to dry the adhering raw seaweed and a stripping section that strips the dried seaweed from the seaweed cage, and the dry seaweed is manufactured by transporting each of these sections.

Conventionally, a press dehydration system has been widely practiced as the dehydration section. The press dewatering method is to arrange the water absorbing members above and below the transport path so as to sandwich the transport path for the seaweed from above and below, and to cause the water absorbing member to move up and down to spread it on the seaweed cage. The water absorbent material is pressed against the seaweed to perform press dehydration.

As the water absorbing member, a sponge having a strong water absorbing property is often used, and the sponge is pressed and dehydrated by pressing it against the raw seaweed spread on the seaweed cage. Therefore, fine raw seaweed is likely to adhere to the surface of the water-absorbing member, and as a result, there is a problem that the water-absorbing member is clogged and the dehydration ability is reduced, and various bacteria are generated in the adhered raw seaweed.

Therefore, it is necessary to appropriately wash the water absorbing member, and thus the water absorbing member has conventionally been washed as follows. That is, the water absorbing member is removed from the mounting plate and washed by hand, or after being cleaned by a cleaning device provided separately from the laver producing device, the water absorbing member is mounted on the mounting plate again.

[0006]

However, in any of the above-mentioned conventional methods, the water absorbing member must be manually removed from the mounting plate, or must be remounted after cleaning, which results in a great labor burden on the worker. There was a problem. By the way, the number of water absorbing members set in the seaweed production device varies depending on the model, but is generally 20.
Since it is more than one sheet, it takes a lot of time and labor to wash all the water absorbing members. In addition, the number of seaweed production units produced varies depending on the model, but is generally 300 per hour.
Since the number of sheets was 0 or more, and therefore the water absorbing member was pressed against the fresh seaweed many times in a short time, the above clogging was likely to occur. Therefore, it is an object of the present invention to provide a laver producing apparatus and a method for washing a water absorbing member in a laver producing apparatus that can easily wash the water absorbing member.

[0007]

To this end, the present invention provides a cleaning liquid for supplying a cleaning liquid to an upper water-absorbing member 35A and a lower water-absorbing member 35B which are provided so as to sandwich the transport path 5 for laver cage 13 from above and below. Supplying means 40a, 40b, 41, 42
And a power connecting / disconnecting portion K4 for connecting / disconnecting the vertical movement of the water absorbing members 35A, 35B by the drive of the drive mechanism 24.

[0008]

According to the above construction, the operation of producing seaweed by the seaweed production apparatus is stopped, the water absorption members 35A and 35B are attached to the seaweed production apparatus, and the water absorption members 35A and 35B are moved up and down while supplying the cleaning liquid thereto. By performing the above, cleaning can be easily performed.

The endless chains 2 and 5, the paper making section 7, the dehydrating section 8 and the stripping section 9 can be driven independently or independently of each other.

This seaweed production apparatus has the above-mentioned structure, and the operation of the whole will be described below. In FIG. 1, the seaweed cage holder 4 is conveyed by the endless chain 5 and stops immediately below the papermaking section 7. In the state where the seaweed cage 13 is temporarily stopped below the paper making section 7, the raw seaweed 15 is made on the seaweed cage 13 by the paper making section 7. Subsequently, the seaweed cage holder 4 moves to the dehydration section 8 and stops there. Then, in FIG. 4, the upper water-absorbing member 35A descends, the lower water-absorbing member 35B rises, and the seaweed cage 13 is sandwiched between the water-absorbing members 35A and 35B from above and below for press dehydration. In this embodiment, as shown in FIG. 4, the water absorbing members 35A, 35B
Are arranged side by side in the transport direction N of the seaweed cage 13, and therefore the raw seaweed 15 on the seaweed cage 13 is pressed and dehydrated twice.

Next, the seaweed holder 4 is sent to the inside of the drying chamber 1 and conveyed inside the drying chamber 1 by the endless chain 2, while the raw seaweed 15 is dried. Next, the seaweed holder 4 is sent out from the drying chamber 1, and the dry seaweed attached to the seaweed 13 is stripped off from the seaweed 13 by the stripping section 9.
Then, the stripped dry seaweed is sent to the next inspection step.

By repeating the above operation, dry seaweed is produced one after another, but since the water absorbing members 35A and 35B are repeatedly pressed against the raw seaweed 15 for dehydration,
Fine raw seaweed adheres to the lower and upper surfaces. As described above, this raw seaweed causes clogging of the water absorbing members 35A and 35B and propagation of various bacteria.

Therefore, the water absorbing members 35A and 35B are appropriately washed as follows. That is, the clutches K1, K2, K3 and K5 shown in FIG. 5 are turned off to stop the driving of the endless chains 2, 5, the paper making section 7 and the stripping section 9, and the seaweed production by this seaweed production apparatus is stopped. On the other hand, only the clutch K4 is turned on, and the dehydration unit 8 is driven, that is, the water absorbing members 35A and 35B are moved up and down. Therefore, water is sprayed from the lower nozzle 40a to the upper water absorbing member 35A, and from the upper nozzle 40b, the lower water absorbing member 35A.
B is sprayed with water, and the water absorbing members 35A and 35B are impregnated with cleaning water. At this time, the clutch K4 is ON and the water-absorbing members 35A and 35B are moving up and down. Therefore, the upper water-absorbing member 35A descends and the lower water-absorbing member 35B ascends, thereby lowering its lower surface and upper surface. The water absorbing members 35A and 35B are pressed against each other to be washed. As described above, when the cleaning water is supplied to the water absorbing members 35A and 35B and both are repeatedly pressed against each other, the cleaning is sufficiently performed.

When the cleaning of the water absorbing members 35A, 35B is completed, all the clutches K1, K2, K3, K
4, K5 to ON, endless chains 2, 5, paper making section 7,
The dehydrating section 8 and the stripping section 9 are driven again to restart the above-described production of dry seaweed. The water absorbing members 35A and 35B may be washed at any time, for example, at the start of operation on that day, every predetermined number of sheets (for example, every 10,000 sheets), or every predetermined time (for example, every 5 hours). You may set it to a microcomputer etc. so that it may perform. The present invention is not limited to the above-mentioned embodiment, and for example, the water absorbing members 35A, 3A may be used as a supply means for supplying the cleaning water to the water absorbing members 35A, 35B.
It may be a means for spraying water from any direction toward 5B.

[0021]

As described above, according to the present invention, the water absorbing members 35A and 35B can be automatically cleaned while they are still attached to the seaweed producing apparatus. In particular, the present invention relates to the water absorbing member 35 for press dehydrating the raw seaweed 15.
Drive mechanism 24 for causing A and 35B to move up and down
Is used as it is as a cleaning mechanism for the water-absorbing members 35A and 35B, the structure of the device is simple and the cost is extremely advantageous, and the water-absorbing members 35A and 35B can be easily cleaned at a desired time. By performing the vertical movement of the water absorbing members 35A and 35B any number of times, the raw seaweed strongly adhered to the water absorbing members 35A and 35B can be sufficiently washed and removed.
