DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for removing raw seaweed garbage.

[0002]

2. Description of the Related Art Conventionally, for example, in the production of dried seaweed, raw seaweed is washed with a washing device while stirring, and the washed seaweed is cut into a size of 5 mm in four directions by a cutting device. It is made by laminating the seaweed, and the raw seaweed is dried by a drying device.

[0003] Since there is a possibility that dust mixed in the raw seaweed may adhere to the dried seaweed, dust is detected by a dust detection device. If no dust is detected, the dried seaweed is left as it is. Products that are shipped as products while dust detection is performed are sent to the dust removal work process.

[0004]

However, in the above-mentioned garbage removal work process, since the garbage adhering to the dried laver is manually removed, labor and labor are required, resulting in poor work efficiency. There is.

[0005]

Therefore, according to the present invention, there is provided a mixing section for mixing raw seaweed and salt water cut to a required size at a fixed weight ratio, and a raw seaweed and salt water mixed by the mixing section. A suction channel portion for sucking the prepared solution, and a filtering portion provided in the suction channel portion for filtering dust in the prepared solution, and a filtering slit having a constant narrow width was formed in the filtering portion. In the raw seaweed trash removal device, the suction flow path can be changed to a suction position that can communicate with the blending unit and suck the formulation liquid, and a non-suction position that is separated from the blending unit and cannot suck the formulation liquid. The present invention provides a refuse removing device characterized by the following.

[0006] The present invention is also characterized in that in a non-suction position, there is provided a filtering section cleaning means for cleaning the deposits on the filtering section of the suction channel section and eliminating clogging.

Slot for forming a slit formed in the outer case forming body 162
164 can be matched with the slit forming long holes 163 formed in the inner case forming body 161.

A salt water supply pipe 83 is connected to the left end of the inner case forming body 161 in communication therewith, while the right end of the inner case forming body 161 is connected to the base end supply side of the filtered raw nori supply pipe 80. The pipe 80a is communicatively connected.

In this manner, the suction case 160 is set to the suction position, as in the dust removal apparatus A of the third embodiment.
The filtering slit 32 → the inner case forming body 161 → the raw seaweed can be sucked while being filtered through the base end supply pipe 80a, while if the filtering slit 32 is clogged, the suction case 160 Is changed to a non-suction position, and during that time, the raw nori in the inner case forming body 161 is sucked, and salt water for backwashing is supplied into the inner case forming body 161 from the salt water supply pipe 83, and the inner side is formed. After the pressure in the case forming body 61 is increased, the backing plate 153 is brought into contact with the stopper body 151 so that the outer case forming body 162 can be smoothly rotated. Slot 164 for slit formation is inner case forming body
All of the slots 163 correspond to the slots 163 for forming a slit.
The salt water is allowed to flow down through 163 and 164, and the attached dust and the like can be washed away.

In this embodiment, the slot for forming the slit is used.
The 163, 164 are formed in two rows on the left and right sides at regular intervals in the circumferential direction. However, the present invention is not limited to this, and three or more rows may be formed in the left and right width direction, or one row may be formed.

Further, in each embodiment, the filtering operation, the back washing operation, and the shower washing operation can be automatically controlled by the control unit 178.

[0065]

According to the present invention, the following effects can be obtained.

The mixing section mixes the raw seaweed cut into the required size and the salt water at a weight ratio such that the raw seaweed can easily pass through the slit for filtration, and puts the prepared liquid into the suction flow passage section. By sucking, the dust in the preparation liquid can be reliably filtered on the way through the filtering slit of the filtering unit.

Accordingly, it is possible to save the trouble of detecting attached dust and removing the dust manually, and it is possible to efficiently produce nori and provide high-quality nori.

Since the suction flow path can be changed between a suction position in which the preparation liquid can be sucked by communicating with the preparation portion and a non-suction position which is separated from the preparation portion and cannot suction the preparation liquid, By changing the posture of the suction flow passage to the non-suction posture, maintenance of the suction flow passage, particularly the filtration unit, can be performed easily.

For example, dust and the like may adhere to the filtration unit and cause clogging. Even in such a case, measures for eliminating the clogging can be taken promptly.

In the non-suction position, in the case where a filter cleaning means is provided for cleaning the deposits on the filter of the suction flow path to eliminate clogging, the filter cleaner may be used to clean the filter. Since the clogging can be eliminated promptly, the filtering function of the filtering section of the suction channel section can be ensured well, and the filtering efficiency can be improved.

Further, since the filtration section can be washed by the filtration section washing means in a state where the suction flow path section is changed to the non-suction state, the deposits on the filtration section can be reliably transferred to the outside of the preparation section. It is possible to wash and discharge, and as a result, it is possible to prevent a repetition of the problem that the adhered substance flows into the blending section again and adheres to the filtering section again at the time of filtration to cause clogging, From this point, the filtration efficiency can be improved.
