[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laver manufacturing apparatus for purifying fresh water, such as tap water, which has been supplied and discharged at each step of a manufacturing process of dried laver, by biological treatment and reusing it. About.

[0002]

2. Description of the Related Art Conventionally, there is an apparatus of this type disclosed in Japanese Patent Application Laid-Open No. Hei 4-30777, which is shown in FIG. FIG. 5 shows a schematic configuration diagram of a conventional laver manufacturing apparatus.

In FIG. 1, a conventional laver production apparatus comprises a stirring and washing step of mixing and agitating seaweed and seawater in a stirring and washing tank 11, and a dehydrating apparatus 12 for removing seawater from a mixture of seaweed and seawater. Dehydration process and mincing device 1
In step 3, a mincing step for mincing the nori original algae, a concentration adjusting step for adjusting the minced nori and fresh water to an appropriate concentration in the concentration adjusting tank 18, and feeding the raw nori cut in the nori sheeting machine 14 onto a nori cage. A paper making process for making paper leaf-like laver, a filtration process for purifying the water discharged from the paper making process with a filtration device 27, and returning to a concentration adjusting tank 18; And a drying step of drying the raw nori.

[0004] In the above-mentioned conventional laver manufacturing apparatus, the paper water generated by draining in the paper making process is supplied to the laver paper making machine 14.
, High-priced tap water is used in large amounts for the adjusted water used in the concentration adjustment step and the papermaking water used in the papermaking step. This concentration adjusting step and the paper making step require a large amount of tap water of 20 to 30 tons per day.

[0005]

Since the conventional laver manufacturing apparatus is configured as described above, a large amount of fresh water is continuously supplied to the concentration adjusting step and the paper making step while the laver is being produced. The cost of the water supply for supplying the freshwater to the seaweed manufacturer and the cost of equipment for forming a well that can pump out high-quality freshwater when supplied from the well are large for the laver manufacturer. There was a problem of burden.

Further, since seawater has been contaminated in recent years, if seawater collected from the vicinity of the bay is directly supplied to the agitation washing tank 11, germs such as Escherichia coli may be mixed in, or garbage or oil floating in the seawater may become seaweed. There is also a problem that it is unsanitary, for example, adheres, and also adversely affects the quality of nori. Therefore, these Escherichia coli and various bacteria may be mixed in the fresh water once used for concentration adjustment or laver preparation, so that the fresh water cannot be reused repeatedly.

[0007] In such a conventional type of laver manufacturing apparatus, a filtration type (filter, sand) -type passage type causes clogging of the filtering device 27 and increases replacement cost, and causes clogging of the filtering device 27. In such a case, a backwashing process is required by the backwashing device, and the cost of the device itself and the manufacturing process increases. In addition to this filtration method, an adsorption method,
There is a coagulation filtration method and the like, and the passage type using this adsorption method (activated carbon etc.) has a limit in the adsorption capacity of the adsorption device, and it is necessary to replace the adsorbent of this adsorption device every time. At the time of clogging, it is necessary to perform backwashing with a backwashing device, and there is a problem that the cost of the device itself and the manufacturing process increases. In addition, the passing type by the above-mentioned coagulation filtration method (coagulant, filter medium) requires a special coagulant, and if this coagulant is used, it becomes difficult to remove the laver pigment, and in the case of the filter medium, clogging occurs. There is a problem that backwashing by a washing device is required, and the cost increases.

The present invention has been made in view of the above problems, and an object of the present invention is to provide an apparatus for producing hygienic dried laver with reduced cost of fresh water supply every time and improved hygienic dry laver. .
