Description

[Detailed description of the invention] The present invention relates to a seaweed moisture detector used in an endless screen type seaweed manufacturing device, and detects the moisture content of the undried seaweed spread on the endless screen running inside the drying chamber. This allows for continuous detection without causing any pain.

Drying the seaweed is an extremely important step in the process of manufacturing dried seaweed, and if it is not dried too much, the seaweed may tear or shrink when it is removed from the screen. This results in a loss of product value.

Therefore, in order to produce high-quality dried seaweed, it is necessary to detect the moisture content of seaweed being dried in the drying chamber as accurately and continuously as possible, and to strictly control the temperature of the drying chamber in accordance with the detection results.

However, in the drying room, the seaweed spread on the cage has a high moisture content and is extremely soft, so if the moisture detector is not suitable, the soft undried seaweed will be disturbed by the moisture detector.

Therefore, the present invention has been developed in consideration of the above points, and is intended to provide a moisture detector that can continuously detect seaweed moisture especially in an endless cage type seaweed manufacturing apparatus. A pair of conductive rolls, whose outer peripheral surfaces are in contact with the seaweed spread on the surface of the seaweed, are placed in parallel at a distance so that they can rotate freely, and the moisture content of the seaweed is detected by the amount of current flowing between the two conductive rolls. This makes it possible to continuously detect moisture in undried, soft seaweed without damaging it.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an overall side view of an endless cage type seaweed manufacturing device,
The endless screen M enters the drying chamber 3 through the papermaking section 1 and the dewatering section 2, and after traveling in the drying chamber 3 in a corrugated manner, passes through the stripping section 4 and returns to the papermaking section 1.
It's like going back to.

A seaweed moisture detector 5 is installed above the approximate center of the drying chamber 3.

6 is a seaweed moisture detector of the second embodiment (described later), which is installed near the entrance of the drying chamber 30.

2 and 3 are a side view and a front view of the seaweed moisture detector 5, which has a moisture content of about 300.
It is installed at about %.

At the lower ends of the pair of support plates 7, 7 constituting the present moisture detector 5, a pair of conductive rolls 8, 8 are rotatably mounted and arranged in parallel at a distance from each other. , 8 are in contact with the undried seaweed m spread on the surface of the endless screen M.

In addition, the outer circumferential surface of each roll 8.8 has knurling to ensure good contact with the seaweed m, to prevent the sensitivity from decreasing due to adhesion of seaweed debris, and not to disturb the soft, undried seaweed m. Eyes are formed.

An insulating rod 9 is pivotally attached to the upper end of each support plate 7.7, and each support plate 7.7 is connected to an arithmetic circuit 10.

In the above configuration, the endless cage M from which fresh seaweed m has been extracted in the extraction section 1 passes through the dewatering section 2 and enters the drying chamber 3.

While traveling in a wave pattern in the drying chamber 3, the raw seaweed m is gradually dried, and when the moisture content has decreased to a considerable degree (approximately 300 parts), moisture detection is performed by the moisture detector 5.

As described above, a pair of rolls 8, 8 are placed in contact with the seaweed m at a distance, and the electrical resistance between each roll 8.8 is inversely proportional to the moisture content of the seaweed m.

Therefore, if the moisture content is excessive, the set value ground current will flow,
Conversely, when the amount of water is too low, only a current below the set value flows.

In this way, depending on the magnitude of the current flowing between each roll 8°8 that rotates in contact with the IC seaweed rrl, the moisture content of the seaweed m is continuously detected, and as a result, the combustion of the burner is turned on and off, etc. You can adjust the temperature by

FIG. 4 shows a seaweed moisture detector 6 according to another embodiment of the present invention, and as shown in FIG. 1, this moisture detector 6 is installed near the entrance of the drying room 30.

This moisture detector 60 has a conductive needle 1 on the outer peripheral surface of the roll 11.
2 are planted in large numbers, and the needles 12 are designed to pierce the seaweed m.

As mentioned above, the moisture content of the seaweed m is extremely high in the early stage of drying, and when the rolls 8 and 8 of the first embodiment are brought into contact with each other, the seaweed m may be disturbed or nori debris may adhere to the roll 8. There is a risk that the sensitivity will decrease.

However, in this example, the contact with 1 m of seaweed is
2, there is no risk of disturbing the seaweed m or adhering seaweed debris to lower the sensitivity, and therefore the moisture in the seaweed m can be reliably detected even in the early stages of drying.

As explained above, the seaweed moisture detector of the endless cage-type seaweed manufacturing apparatus according to the present invention is equipped with a pair of seaweed moisture detectors whose outer peripheral surfaces are in contact with the seaweed m spread on the surface of the endless cage M running inside the drying chamber 3. Since the conductive row/I/8 and 11 are rotatably arranged side by side at intervals, moisture detection can be carried out continuously without damaging the undried, soft seaweed.
