Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to a seaweed drying device, in which a heat dissipation tube connected to a heat generating section is disposed between the upper and lower stages of the endless transport path of the screen, and The seaweed spread on the screen is dried by heat dissipation from the heat dissipation tube.

(Background of the Invention) FIG. 3 shows a seaweed drying apparatus that has been widely implemented in the past, in which a heat exchange chamber 32 is arranged on the side of a drying chamber 31, and outside air is introduced by a fan 33. The heated air is then heated by heat dissipation from the heat exchange duct 34, and the warmed air is sent to the lower part of the drying chamber 31, blown upward, and spread on the cage 35, which is conveyed onto the endless conveyance path 37 inside the drying chamber 31. It was designed to dry 36 sheets of seaweed. 38 is a burner connected to the heat exchange duct 34. However, in such a seaweed drying apparatus, the seaweed 36 with a low moisture content just before the end of drying on the lower stage B side
The drying efficiency is not increased because the drying efficiency is not increased because the drying efficiency is not increased because the seaweed 36 on the upper stage A side with a high moisture content in the early stage of drying is hit by the seaweed 36 on the lower stage B side with a low moisture content. Seaweed 3 due to exposure to high temperature air
No. 6 had problems such as being prone to cracking due to excessive drying.

(Summary of the Invention) The present invention has been made in consideration of the above points, and an object of the present invention is to apply high temperature air to seaweed with a high moisture content to promote drying and prevent cracking. To provide a seaweed drying device capable of producing high-quality dried seaweed. For this purpose, the present invention provides a seaweed drying apparatus that dries the seaweed spread on the cage while transporting the cage along the endless transportation path provided in the drying chamber. A heat dissipation pipe is disposed between the upper stage and the lower stage, and the heat dissipation pipe is connected to a heat generating section. By configuring the seaweed drying apparatus in this way, high-temperature air is applied to the seaweed in the early stage of drying, which has a high moisture content, to accelerate drying and produce high-quality dried seaweed without cracks.

(Example) Hereinafter, an example of the present invention will be described with reference to each figure.

FIG. 1 is a front view of a seaweed drying apparatus according to the present invention, in which 1 is a drying chamber, and a seaweed 3
The bamboo basket 2 on which is spread out is being transported. The drying room 1
The upper part of the exhaust fan 12 is closed by a sealing member 1a to form a sealed or substantially sealed structure.
Due to the ventilation action (described later), the drying chamber 1 is brought into a slightly reduced pressure state. 4 is a holder for screen 2,
It is loaded on the endless chain 5. The endless chain 5 circulates within the drying chamber 1, and the screen 2 attached to the holder 4 is sent to the upper stage A side of the endless chain 5 and is conveyed from the upper stage A side to the lower stage B side, and the screen 2
When the drying of the seaweed 3 spread on the drying chamber 1 is completed, it is carried out of the drying room 1. A side chamber 6 is provided on one side of the drying chamber 1, and communicates with the drying chamber 1 through an opening 18 provided at the bottom of the drying chamber 1.

Reference numeral 9 denotes a heat exchanger disposed on the upper side of the drying chamber 1, and its surfaces 9a, 9b, 9c, and 9d are connected to the drying chamber 1, the side chamber 6, and the discharge port 10, respectively.
It communicates with the outside air intake port 11. Reference numeral 12 is an exhaust fan, and due to the exhaust action of the fan 12, the inside of the drying chamber 1 is brought into a slightly reduced pressure state. 13 is a damper for adjusting air volume. Reference numeral 14 denotes a heat dissipation tube horizontally arranged between the screen 2 of the upper stage A and the screen 2 of the lower stage B, and its details will be explained next with reference to FIG. 2.

The heat dissipation tube 14 is connected to the screen 2 held in the holder 4.
There are three, corresponding to the number of drying chambers 1, and they are arranged horizontally at equal intervals in the length direction of the drying chamber 1. Reference numeral 15 denotes an air pipe, and each of the heat radiators 14 is connected to this air pipe 15. This air pipe 15 is connected to a burner 8 as a heat generating section, and the hot air generated by the burner 8 passes through the air pipe 15 to each heat radiation pipe 14.
sent to. Reference numeral 16 is an exhaust pipe to which the other end of each of the heat dissipation pipes 14 is connected, and the tip thereof is connected to the drying chamber 1.
It extends outward and is connected to the chimney pipe 7. 17 is a damper disposed on the upper part of the side wall 6;
When the damper 17 is opened as shown by the solid line in FIG. 1, a portion of the humid warm air headed for the heat exchanger 9 is returned into the side chamber 6 and enters the drying chamber 1 again through the opening 18.

This device consists of the above-mentioned configuration, and has 8 burners.
The heated air is sent to the heat radiation pipe 14 through the air pipe 15. Inside the drying chamber 1, a cage 2 is transported from an upper stage A to a lower stage B, and a heat dissipation pipe 1
The high temperature air warmed by the heat dissipation in step 4 is transferred to the upper stage A.
After hitting the seaweed 3 with a high moisture content in the early stage of drying and drying it significantly, it is transferred to the heat exchanger 9 as shown by the arrow B due to the exhaust action of the fan 12.
It is discharged from the drying chamber 1 through the discharge port 10. In addition, the outside air passes through the heat exchanger 9 as shown by arrow A, enters the rear chamber 6 where it removes residual heat from the exhaust gas, and then enters the lower part of the drying chamber 1 through the opening 18 and is blown upward to the lower stage B. Dry the seaweed 3 which has a low moisture content in the late drying stage. In this way, the warm air hitting the seaweed 3 on the lower tier B side is at a relatively low temperature, so the seaweed 3 will not crack due to excessive drying. Seaweed 3 on the lower B side
When the air blows up from the lower stage B to the upper stage A, it is heated to a high temperature by heat radiation from the heat radiation pipe 14, and hits the seaweed 3 on the upper stage A side as described above, significantly drying it. Also damper 17
If it is left open, a part of the warm air heading for the heat exchanger 9 will enter the side chamber 6, and then enter the drying chamber 1 through the opening 18.
Enter. This warm air has considerable residual heat,
In addition, since the moisture is removed from the seaweed 3 and it has a suitable humidity, if the humid warm air is returned to the drying chamber 1 and applied to the seaweed 3 on the lower stage B side in the late drying stage, the seaweed 3 can be properly moistened. It is possible to dry the material while adding moisture to prevent cracking. In this way, according to the present device, high-temperature warm air can be blown onto the seaweed 3 with a high moisture content on the upper stage A side from a short distance, so that the drying of the seaweed 3 can be significantly accelerated. Furthermore, since relatively low temperature warm air hits the seaweed 3 with a low moisture content on the lower stage B side, high quality dried seaweed can be produced without cracking due to excessive drying.

The present invention is not limited to the embodiments described above, and various design changes are possible. For example, the heat dissipation tubes may be arranged in a curved shape such as a meandering shape. Furthermore, the present invention can also be applied to a type of seaweed drying apparatus in which the screen 2 is not attached to the holder 4 and is transported on a transport path within the drying chamber 1.

(Effects of the Invention) As established above, the seaweed drying device according to the present invention can significantly accelerate the drying of the seaweed 3, has extremely high thermal efficiency, and produces crack-free, high-quality dried seaweed. can be manufactured.
