DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to laver nets spread on laver farms and laver propagated on laver nets.
TECHNICAL FIELD The present invention relates to a laver net chemical treatment device that performs various chemical treatments such as acid treatment.

[0002]

2. Description of the Related Art In general, seaweed cultivation is carried out by attaching a float to a seaweed net and then floating the seaweed on the sea surface and stopping it with an anchor. It is performed by the supporting column method. The proper use of both types is determined by the location conditions of the farm.

A seaweed farm using the above-mentioned strut system is located near the shore where a strut can be erected and at a shallow depth of water. The bactericidal effect of various germs attached to the seaweed by the sun is great, which is a desirable method for cultivation of seaweed.

[0004] In such a nori cultivation, seaweed is harvested from a nori net, and floating substances such as seawater scales and dust are attached to the surface of the nori net and the nori breeding on the nori net. There are factors that reduce the quality of nori, such as the propagation of various bacteria, and to grow high-quality, healthy nori and improve the harvest rate, two to three times between harvesting and cutting the nori Chemical treatment using various chemicals represented by acid treatment has been performed on laver nets and laver that propagates on the laver nets. Further, even after cutting the laver, a chemical treatment operation using various chemicals represented by acid treatment is performed on the laver net. In such chemical treatment of the laver net, a treatment solution adjusted to a predetermined pH value is sprayed onto the laver net, or a predetermined pH value is set in the treatment tank.
The treatment is performed by, for example, putting a treatment liquid adjusted to a value and dipping a laver net into the treatment liquid in the treatment tank.

[0005]

However, in the case where the treatment liquid adjusted to the above-mentioned predetermined pH value is sprayed onto the laver net, the treatment liquid cannot be uniformly penetrated over the entire laver net. However, there is a problem that the contact time of the treatment liquid with the laver net is short, and effective chemical treatment cannot be performed.

On the other hand, a processing solution adjusted to a predetermined pH value is put into the above-mentioned processing tank, and a laver net is added to the processing liquid in the processing tank.
In the immersion method, the treatment liquid can be uniformly brought into contact with the entire laver net, and while the contact time of the treatment liquid with the laver net can be sufficiently ensured, the laver net containing seawater is not immersed. Because it is immersed in the processing solution,
There is a problem that the treatment liquid is diluted with seawater, and the pH value of the treatment liquid cannot be maintained within an effective range of the chemical treatment.

[0007] The present invention has been made in view of these points, and an object of the present invention is to provide a laver net drug treating apparatus capable of maintaining the pH value of a treatment solution within an effective range for drug treatment. I do.

[0008]

In order to achieve the above-mentioned object, a laver net drug treating apparatus according to the present invention comprises an auxiliary tank, a laver net processing tank, and a drug supply means for supplying a drug into the auxiliary tank. A diluent supply means for supplying a diluent into the auxiliary tank, a pH detection means for detecting a pH value of a treatment liquid comprising a drug and a diluent supplied to the auxiliary tank, Circulating means for circulating the processing liquid between the net processing tank and the auxiliary tank so as to maintain the pH value of the processing liquid in the auxiliary tank within a predetermined range based on the detection result by the pH detecting means.
