Seaweed drying system

Abstract

To provide a seaweed drying system which can suppress excessive temperature rise of seaweed at the time of drying.SOLUTION: A seaweed drying system according to an aspect of the present invention is a seaweed drying system having a drying device 30 for drying seaweed collected from under the sea. The seaweed drying system includes a color detection part 10 for detecting a change in the color of seaweed while the seaweed is dried by the drying device 30. When the color detection part 10 detects the change in the color of the seaweed, the seaweed drying system lowers the temperature of air blown onto the seaweed.SELECTED DRAWING: Figure 1

Summary of the Invention

Problems to be Solved by the Invention

[0004] The inventors have found that when the temperature of seaweed rises too much during drying, active ingredients such as alginic acid will flow out.

[0005] The present invention has been made in view of such circumstances, and provides a seaweed drying system capable of suppressing the excessive rise in the temperature of seaweed during drying.

Means for Solving the Problems

[0006] A seaweed drying system according to an aspect of the present invention is a seaweed drying system including a drying device for drying seaweed collected from the sea, comprising a color detection unit for detecting a change in the color of the seaweed while the seaweed is being dried in the drying device, and when the color detection unit detects a change in the color of the seaweed, the temperature of the air sprayed onto the seaweed is lowered.

[0007] A seaweed drying system according to one aspect of the present invention includes a color detection unit that detects a change in the color of seaweed while the seaweed is being dried in a drying device, and when the color detection unit detects a change in the color of the seaweed, the temperature of the air blown onto the seaweed is lowered. Therefore, it is possible to suppress the temperature of the seaweed during drying from rising too much.

[0008] When the color detection unit detects a change in the color of the seaweed, the amount of air blown onto the seaweed whose color has changed may be reduced.

Advantages of the Invention

[0009] According to the present invention, it is possible to provide a seaweed drying system capable of suppressing the temperature of seaweed from rising too much during drying.

Embodiments for Carrying Out the Invention

[0011] Hereinafter, specific embodiments to which the present invention is applied will be described in detail with reference to the drawings. However, the present invention is not limited to the following embodiments. Also, for clarity of explanation, the following description and drawings are simplified as appropriate.

[0012] (First Embodiment) First, with reference to FIG. 1, the configuration of a seaweed drying system according to the first embodiment will be described. FIG. 1 is a block diagram showing the configuration of a seaweed drying system according to the first embodiment. As shown in FIG. 1, the seaweed drying system according to the present embodiment includes a color detection unit 10, a drying control unit 20, and a drying device 30. As shown in FIG. 1, in the drying device 30, seaweed collected from the sea is dried.

[0013] The color detection unit 10 is, for example, a color sensor that detects changes in the color of seaweed while the drying device 30 is drying the seaweed and outputs the detection results to the drying control unit 20. Here, the color of seaweed changes when the temperature rises. For example, in the case of wakame, when the temperature increases, it changes from brown to green. If the temperature of the seaweed during drying rises too much, active ingredients such as alginic acid will flow out.

[0014] The drying control unit 20 acquires the detection results from the color detection unit 10 and controls the drying device 30 based on the detection results. When the color detection unit 10 detects a change in the color of the seaweed, the drying control unit 20 controls the drying device 30 to lower the temperature of the air blown onto the leaf part or female plant part where the color has changed. Further, when the color detection unit 10 detects a change in the color of the seaweed, the drying control unit 20 may control the drying device 30 to reduce the amount of air blown onto the leaf part or female plant part where the color has changed.

[0015] Although not shown, the drying control unit 20 includes, for example, an arithmetic unit such as a CPU (Central Processing Unit) and a storage unit such as a RAM (Random Access Memory) and a ROM (Read Only Memory) that store various programs and data. That is, the drying control unit 20 has the function of a computer and executes control processing based on the above various programs and the like.

[0016] The drying device 30 is a device for drying seaweed. For example, it blows air at a predetermined temperature onto the seaweed to dry it. The drying device 30 has, for example, a plurality of air nozzles (not shown) and may blow air at different temperatures and amounts onto each of the leaf part and female plant part of the seaweed based on the control signal acquired from the drying control unit 20.

[0017] As described above, the seaweed drying system according to the present embodiment includes a color detection unit 10 that detects a change in the color of seaweed while the seaweed is being dried in the drying device 30. When the color detection unit 10 detects a change in the color of the seaweed, the temperature of the air blown onto the seaweed is lowered. Therefore, it is possible to prevent the temperature of the seaweed from rising too much during drying.

[0018] Note that the present invention is not limited to the above-described embodiment, and can be appropriately modified without departing from the gist thereof. For example, the color detection unit 10 may be an imaging unit such as a camera. That is, the drying control unit 20 may control the drying device 30 based on a change in the color of the image of the seaweed captured by the imaging unit. In addition, the present invention promotes the use of blue carbon (seaweed) and contributes to carbon neutrality, decarbonization, and sustainable development goals (SDGs: Sustainable Development Goals).
