Description

[Detailed explanation of the idea] "Industrial application field" This proposal concerns a seaweed drying device.

"Prior Art" Conventionally, in a nori drying device, the nori paper cages supported by the nori cage support frame at the upper horizontal transition part and the lower horizontal transition part of the endless intermittent rotating chain are arranged so that the vertical horizontal transition parts are opposite to each other. The dried seaweed paper basket is taken out at the front opening. The hot air is allowed to pass in the vertical direction of the vertical horizontal transition section.

"Problems to be Solved by the Invention" In the conventional drying device described above, as shown in FIG. Ta. However, since the parallel seaweed paper cages that move inside the drying chamber 1' are parallel to the combustion tube 11' in the hot air generation chamber at right angles to the combustion tube 11', they are closer to each other than those that are further away from the combustion tube 11'. The problem was that the temperature of the hot air was extremely high, the hot air circulated quickly, and it was susceptible to the effects of radiant heat from the combustion tube 11', resulting in over-dry areas in the parallel nori paper cages. In addition, new, cold air constantly enters the drying chamber, resulting in poor fuel efficiency.If there are parts of the drying chamber that are not filled with nori sheets at the start and end of the workday, the humidity in the drying chamber decreases, causing the drying chamber for laver sheets to dry ( There was a problem in that a large amount of dry seaweed was produced which lacked flexibility (hardening and cracking), resulting in a decrease in commercial value. This method enables uniform drying in the drying room regardless of the distance from the hot air generation chamber, and even if there are parts of the drying room where the nori paper basket is not filled at the beginning and end of the workday, the dryer for the paper-made nori can be used. The purpose of this invention is to provide a seaweed drying device that prevents this problem and has good fuel efficiency.

``Means to solve the problem'' This plan installs an endless intermittent rotating chain from the front of the nori drying room toward the back, and erects a large number of nori cage support frames on the chain. In a seaweed dryer with multiple hot air generation chambers installed side by side along the side,
A ventilation space that communicates with the drying chamber from the bottom of the hot air generation chamber and a ventilation space that communicates with the drying chamber from the top of the hot air generation chamber are provided alternately in each hot air generation chamber, and each of the ventilation spaces has an upper and lower ventilation space. A plurality of ventilation guide plates are provided in the direction, both ends of each stage of ventilation guide plates are extended into the drying chamber and the hot air generation chamber, and the extended ends of each guide plate on the drying chamber side are directed in the vertical direction. ,
A rotatable air volume adjustment plate is provided at the extended end of each guide plate on the side of the hot air generation chamber, an operating rod is connected to each air volume adjustment plate, and each air volume adjustment plate is rotated based on the operation of these operation rods. A blower that can be moved to independently adjust the area of the opening at each extension end, and that introduces outside air into each hot air generation chamber with a ventilation space below and sends it to each ventilation guide plate in the same room. In addition, each hot air generation room with a ventilation space above is equipped with a blower that circulates the hot air from the drying room back to the drying room via each ventilation guide plate in the same room. It consists of a seaweed drying device with the following characteristics.

"Function" Therefore, hot air is blown from the hot air generation chamber 2 through the ventilation space 3 into the drying chamber 1, and the nori paper making basket is supported on the nori basket support frame 10 in the drying chamber 1, and an endless intermittent rotating chain is formed. 9, 9 are rotated intermittently, the cage moves in the opposite direction at the upper and lower transition parts, and the hot air passes between the nori paper cages in the upper and lower transition parts to dry the paper-made nori. The hot air that enters the opening 7 between the extended ends 6, 6 of the ventilation guide plates 4 arranged in the vertical direction in the hot air generation chamber 2 passes between the same guide plates 4, 4 and passes through the other extended ends 5, 5. The paper-made seaweed is discharged from the space in the vertical direction and passes through the paper-made nori cages on the support frame 10 arranged perpendicularly to the chain 9 to dry the paper-made nori. The extended ends 5 and 6 are arranged parallel to the chain 9, and arranged perpendicularly to the chain 9, so that the hot air is guided in an orderly manner by the extended ends 5 and 5 on the drying chamber 1 side, and is immediately processed into nori sheets without being disturbed. It enters and passes between the cages. Then, the wind adjusting plates 7' provided at the extended ends 6, 6 of the ventilation guide plate 4 are adjusted independently using the operating rod 14 according to the temperature of the hot air entering the ventilation guide plate 4, and each opening is Adjust the area of 7. As a result, the amount of hot air entering through each opening 7 is adjusted, and the optimum amount of heat can be supplied depending on the position of the nori paper cage arranged in the drying chamber 1. In addition, the plurality of hot air generation chambers 2, 2 are alternately blown in the hot air direction in the upside down direction, and the hot air is blown downward.
(Figure 3), hot air circulates between both chambers 1 and 2, moisture does not escape to the outside, and the paper-made seaweed is kept moisturized, and since there is little intrusion of cold air from the outside, less heat is lost to the outside. . In addition, the above-mentioned generation chamber 2 blows hot air upward.
(Figure 2), a lot of outside air enters and releases moisture, but a lot of cold air enters and a lot of heat escapes, so overdrying can be prevented by repeating moisturizing and drying alternately.

"Example" Two endless intermittent rotating chains 9, 9 are arranged from the front of the front-opening nori drying chamber 1 toward the back of the chamber 1, and a large number of nori cage support frames 10 are installed in the chains 9, 9. will be constructed in close proximity. On one side of the drying chamber 1, there are multiple (6
A combustion furnace 11 and a hot air cylinder 12 connected to the combustion furnace 11 are arranged in parallel with the chain 9 inside the generation chamber 2.
is connected to the upright chimney 12'. A blower 13 is disposed in the hot air generation chamber 2, and the hot air generation chamber 2 and the drying chamber 1 are communicated with each other through the ventilation space 3 to form a seaweed dryer. The ventilation spaces 3 are provided alternately below (FIG. 2) and above (FIG. 3) the upper and lower nori cage support frames 10.
That is, ventilation spaces 3 communicating with the drying chamber 1 from the lower side of the hot air generation chamber 2 and ventilation spaces 3 communicating with the drying chamber 1 from the upper side of the hot air generation chamber 2 are provided alternately in the hot air generation chamber 2. It is being The upper ventilation space 3 supports a plurality of stages of ventilation guide plates 4 as shown in FIGS. 2 and 3, and each stage of ventilation guide plates 4 is arranged in an arc shape inside the drying chamber 1 and the hot air generation chamber 2, respectively. It is curved and extended, and is supported with the extension ends 5 and 6 facing upward and downward, respectively. Air volume adjusting plates 7' are rotatably supported in the openings 7 between the extension ends 6 and 6 on the hot air generation chamber 2 side, respectively, and operating rods 14 are connected to the plates 7', respectively. is slidably projected to the outside of the outer surface of the hot air generation chamber 2, and the operating rod 14 is slidably adjusted to form an air volume adjustment device 8.

Since high-temperature hot air is supplied to the nori paper cage located close to combustion 11, the above combustion 11
A nearby air volume adjustment plate 7' is rotated via the operating rod 14, and the area of the opening 7 at this position is narrowed to limit the air volume. In addition, since hot air having a lower temperature is supplied to the nori paper cage located far from the combustion furnace 11 than to the nori paper production cage located close to the combustion furnace 11, the air volume adjustment plate 7 located far from the combustion furnace 11 is supplied with hot air having a lower temperature. ' to increase the area of the opening 7 at this position and increase the air volume.

By making such an adjustment, it is possible to give the optimum amount of heat to the nori paper making cage on the far side from the nori paper making cage on the side near the combustion furnace 11, and in particular, it is possible to give the nori paper making cage on the far side from the nori paper making cage on the side close to the combustion furnace 11. It is possible to effectively prevent the papermaking cage from becoming excessively dry.

In addition, since outside air is introduced from the blower 13 into the hot air generation chamber 2 (Fig. 2), which has the ventilation space 3 on the lower side, a relatively large amount of moisture is released. In the hot air generation chamber 2 (FIG. 3), the hot air from the drying chamber 1 is circulated again to the drying chamber 1 side by the blower 13, so that the paper-made seaweed can be kept moist without moisture escaping to the outside. Therefore, in the direction of movement of the chain 9, drying and moisturizing are repeated, thereby preventing a decrease in humidity in the drying chamber and further preventing deterioration of fuel efficiency. In the figure, 15 indicates a partition plate for each hot air generation chamber 2 provided in the drying chamber 1, 16 indicates a partition plate provided for each ventilation space 3 of each hot air generation chamber 2, 17 indicates a blower 13, and 18 indicates a prime mover. An air guide plate, 19 an outside air intake opening/closing plate, and 20 a burner.

``Effects'' Since the present invention is constructed as described above, by adjusting the air volume adjustment plate 7' based on the operation of the operating lever 14, the hot air generation chamber 2 side can be applied to a plurality of nori sheets lined up perpendicularly to the transfer direction. The optimal amount of heat can be given to those closest to those farthest from each other, and over-drying can be prevented.

Furthermore, since the blower 13 is configured to alternately repeat the introduction of outside air and the circulation of hot air, in the direction of movement of the chain 9, drying and moisturizing are repeated alternately for each of the hot air generation chambers 2 and 2, and the nori paper cage is moved into the drying chamber 1. Even if the inside of the drying chamber 1 is not sufficiently filled, it is possible to prevent a decrease in the humidity in the drying chamber 1, which is safe because there is no risk of overdrying, and it is possible to appropriately prevent the dissipation of heat and improve the energy saving effect. can.
