Description

Technical Field

[0001] The present invention relates to the field of drying, and particularly to a continuous dryer for producing selenium-rich fish filaments with zoning. Background Art

[0002] During the drying process of fish filaments, due to the high water content of fish filaments and the presence of fat and grease, dehydration is relatively difficult. Currently, the fish filaments are often dried by a combination of a circulating hot air drying device and manual labor. That is, after drying for a period of time, the fish filaments are manually taken out, left standing for a short period of time, and then put back into the drying device again. This process is repeated multiple times for intermittent drying of the fish filaments. This can timely remove the water vapor evaporated from the fish filaments and prevent the water on the fish filaments from being over-dried, which affects the taste of the fish filaments. However, this operation that requires manual repeated removal and replacement of the fish filaments from the drying device not only takes a long time but also has low work efficiency.

[0019] The driving component includes a fixing block 101 and a motor 102; four annularly distributed fixing blocks 101 are fixedly connected to the lower side of the base 1004 of the dryer 1; a motor 102 is fixedly connected to each fixing block 101, and the output end of each motor 102 is fixedly connected to the adjacent connecting pipe 4 located at the bottommost, and the adjacent connecting pipe 4 is driven to rotate by the motor 102, and then the adjacent arc plate 5 is driven to rotate, so that the fish filaments in the dryer 1 are moved to the outside, realizing static placement.

[0020] The plugging assembly includes a mounting block 401, a circular plate 402 and an elastic member 403; an inner tube 2002 is arranged in the air inlet pipe 2, and each air vent pipe one 2001 is fixedly connected to the inner tube 2002; a plurality of mounting blocks 401 are slidably connected to the air inlet pipe 2; each mounting block 401 is provided with an air vent pipe two 40101, and each air vent pipe two 40101 is located in the adjacent air vent pipe one 2001; each mounting block 401 is fixedly connected to a circular plate 402 through two round bars; an elastic member 403 is fixedly connected between each mounting block 401 and the inner tube 2002, and the elastic member 403 is a spring, and the elastic member 403 is in a compressed state initially.

[0021] It further includes a spacer 301; a spacer 301 is fixedly connected to the outer edge of each supporting net 6.

[0022] The suction port 4001 of each connecting pipe 4 faces the side of the arc-shaped plate 5.

[0023] Each supporting net 6 is provided with a connecting portion 6001.

[0024] The connecting portion 6001 of each supporting net 6 is made of a heat-insulating material.

[0025] A rubber layer is provided at the fitting portion of each supporting net 6 and the arc-shaped plate 5.

[0026] The working steps of this embodiment are as follows: Manually insert the supporting nets 6 evenly laid with fishing lines into the placement grooves 5001 of the arc-shaped plate 5 in sequence, then start the external pump one, so that the hot air enters the air inlet pipe 2 through the air inlet 1002, and then blows into the dryer 1 through the air vent pipe one 2001. At the same time, start the external pump two, so that the suction port 4001 of the connecting pipe 4 generates a suction force, and the hot air is discharged through the suction port 4001 of the connecting pipe 4. It should be noted that the supporting net 6 is located at the middle position of the air vent pipe one 2001. When the hot air blows out from the air vent pipe one 2001, a part of the hot air flows through the upper surface of the fishing line and is sucked away by the suction port 4001, while another part of the hot air flows through the lower surface of the fishing line and is sucked away by the suction port 4001, so as to realize the circulating hot air drying of the fishing line and is beneficial to the uniformity of the drying of the fishing line.

[0027] The existing circulating hot air drying equipment dries the fish filaments in a way that requires manual cooperation. It needs manual operations to repeatedly take out and put back the fish filaments from the drying equipment, which not only takes a long time but also has low work efficiency. To solve the above problems, it can be elaborated in two cases. In the first case, the supporting net 6 with fish filaments laid on it is manually inserted into the placement groove 5001 of the arc-shaped plate 5 in sequence until the entire dryer 1 is filled with fish filaments. Then, the external pump 1 and external pump 2 are started to conduct circulating hot air drying on the fish filaments. When the drying time reaches the set time (about 2 - 4 hours each time), with the view from bottom to top as the reference, the motor 102 is controlled to drive the adjacent connecting pipe 4 to rotate clockwise, thereby driving the adjacent arc-shaped plate 5 to rotate, so that the arc-shaped plate 5 drives the fish filaments on the adjacent supporting net 6 to rotate outward together, thus moving away from the drying chamber of the dryer 1. After standing for a period of time, the motor 102 is controlled to drive the adjacent connecting pipe 4 to rotate counterclockwise, so that the arc-shaped plate 5 drives the fish filaments on the adjacent supporting net 6 to return to the drying chamber again, thereby realizing intermittent continuous drying. After drying is completed, only need to manually take out the supporting net 6 on the dryer 1 in sequence, and then insert the fish filaments to be dried placed on the supporting net 6 in the next batch into the placement groove 5001 of the arc-shaped plate 5, and repeat the above steps. Compared with the existing hot air drying equipment that requires manual cooperation to repeatedly move the fish filaments out of the drying chamber for standing and then move them back into the drying chamber for continuous drying, the present invention only needs simple manual loading and unloading, greatly improving the drying efficiency of the fish filaments.

[0028] The second case is that due to the different production processes of different types of fish, the production time of the fish filaments is also different. When drying, they are not completely in the same batch. At this time, the dryer 1 is divided into four non-connected drying chambers by the partition plate 3, and the fish filaments in different time batches are put into different drying chambers in sequence. According to the time difference of the fish filaments put into the drying chambers, when the fish filaments in the corresponding drying chamber reach the set drying time (2 - 4 hours), repeat the intermittent continuous drying method in the above first case to conduct zoned drying according to the time difference of the fish filaments put into the drying chambers, so as to avoid mutual interference between adjacent drying chambers. When the fish filaments in a certain drying chamber are dried, the fish filaments can be taken out, and then new fish filaments are manually filled in. After the fish filaments in other drying chambers are dried, repeat the above steps, thereby realizing zoned and continuous drying.

[0029] To facilitate the operator to check the drying degree of the fish filaments, without affecting the drying process, the operator can manually pull the supporting net 6 outwards so that the supporting net 6 slides outwards in the placement groove 5001 of the arc-shaped plate 5 until some of the fish filaments on the supporting net 6 are exposed to the outside. To facilitate the operator to quickly pull the supporting net 6 outwards, the operator can directly hold the connecting part 6001 and pull it outwards, improving its operation convenience. At the same time, by setting the connecting part 6001 as a heat-insulating material, it effectively avoids scalding the operator. Then the operator can directly pick up the fish filaments on the supporting net 6 for inspection. Compared with observing the drying degree of the fish filaments through the glass, the operator can directly pick up the fish filaments to intuitively feel the dryness, hardness and elasticity of the fish filaments, thus effectively avoiding misjudgment caused by the glass. At the same time, there is no need to start the device to completely pull the arc-shaped plate 5 outwards, preventing the outside cold air from entering the drying chamber to the greatest extent, reducing the heat dissipation in the drying chamber, and reducing the impact on the drying effect of the fish filaments. At the same time, since the suction port 4001 of each connecting pipe 4 faces the side of the arc-shaped plate 5, when the operator pulls the supporting net 6 outwards, the hot air escaping outwards is sucked through the suction port 4001 of the connecting pipe 4, preventing the hot air from directly rushing towards people and causing scalding. Further, after the manual inspection is completed, the supporting net 6 is pushed back into the placement groove 5001 of the arc-shaped plate 5. Since rubber layers are provided at the fitting parts of the supporting net 6 and the arc-shaped plate 5, during the loading and unloading process by the operator, the placement stability of the supporting net 6 is improved, and at the same time, the airtightness can also be enhanced through the rubber layer to prevent the hot air from leaking outwards and ensure the drying effect of the fish filaments.

[0030] When the operator inserts the supporting net 6 with the fish filaments laid on it into the placement groove 5001 of the arc-shaped plate 5 and takes it out from the dryer 1, due to the instability during the transfer process, the fish filaments at the edge of the supporting net 6 may fall off. To avoid the above situation, by adding a spacer 301 on the supporting net 6, the spacer 301 blocks the edge of the supporting net 6, thereby preventing the fish filaments from falling off the edge of the supporting net 6 and avoiding waste of resources.

[0031] It should be noted that during the drying process of the fish filaments, when the motor 102 drives the adjacent connecting pipe 4 to rotate clockwise, causing the arc-shaped plate 5 to drive the fish filaments on the adjacent supporting net 6 away from the drying chamber for static placement, as the arc-shaped plate 5 opens, the hot air in each drying chamber will dissipate outward. To reduce energy loss and save energy, by adding the embedded pipe 2002, the mounting block 401, the circular plate 402, and the elastic member 403, when the connecting pipe 4 drives the arc-shaped plate 5 and the supporting net 6 to move outward from the dryer 1, the spacer 301 will move outward together with the supporting net 6. At this time, the mounting block 401 is no longer squeezed by the spacer 301, and the elastic member 403 pushes the corresponding mounting block 401 to move away from the air inlet pipe 2. The mounting block 401 drives the adjacent circular plate 402 to block the nozzle of the first ventilation pipe 2001, so that the first ventilation pipe 2001 is no longer connected to the air inlet pipe 2, thereby preventing the hot air from continuously spraying out when the fish filaments on the supporting net 6 are in a static state, thus saving energy. At the same time, when an operator manually pulls out the supporting net 6 to check the drying degree of the fish filaments, the corresponding first ventilation pipe 2001 can also be blocked by the spacer 301, the mounting block 401, the circular plate 402, and the elastic member 403, thereby preventing the hot air from spraying out through the gap between the supporting net 6 and the placement groove 5001 and scalding the employees. It should be noted that when inserting the supporting net 6 with the fish filaments laid into the placement groove 5001 of the arc-shaped plate 5, the spacer 301 pushes the mounting block 401 to move towards the air inlet pipe 2, the elastic member 403 is compressed, and the circular plate 402 no longer blocks the first ventilation pipe 2001.

[0032] Embodiment 2 Based on Embodiment 1, as Figure 5 shown, it further includes a sealing plate 201; a plurality of sealing plates 201 are fixedly connected between adjacent two partition plates 3, and each sealing plate 201 is located below the adjacent supporting net 6; the first ventilation pipe 2001 of each air inlet pipe 2 is located between the two adjacent sealing plates 201 up and down, and the suction port 4001 of the part of the connecting pipe 4 located between the two adjacent sealing plates 201 is located above the corresponding supporting net 6.

[0033] Each sealing plate 201 is made of heat-insulating material.

[0034] The working steps of this embodiment are as follows: When drying the fish filaments, most of the moisture will be discharged through the suction port 4001 of the connecting pipe 4. However, there is still some moisture that will float upward and accumulate on the upper-layer fish filaments, resulting in the upper-layer fish filaments being in a high-humidity environment where the water evaporation is slow, causing the drying degree of the upper and lower layers of fish filaments to be inconsistent and affecting the drying effect of the fish filaments. To avoid the above situation, the fish filaments on each supporting net 6 are separated by the sealing plate 201, so that the same drying chamber is also divided into several small drying chambers, and the adjacent small drying chambers do not interfere with each other, preventing the moisture from floating up to the upper-layer fish filaments during the drying process and affecting the upper-layer fish filaments, thereby further improving the drying effect of the fish filaments. At the same time, by setting the sealing plate 201 as a heat-insulating material, the heat transfer between the upper and lower layers is reduced, enabling the fish filaments to be dried in a relatively independent temperature environment, which helps to maintain the stability of the drying temperature and improve the drying effect.

[0035] Moreover, when circularly drying the fish filaments on the supporting net 6, since the supporting net 6 is located in the middle of the first ventilation pipe 2001 and the suction port 4001 of the part of the connecting pipe 4 located between two adjacent sealing plates 201 is above the corresponding supporting net 6, when drying the fish filaments, a part of the hot air flow is drawn away by the suction port 4001 after flowing through the upper surface of the fish filaments, while another part of the hot air passes through the supporting net 6 from bottom to top and is then drawn away by the suction port 4001, which further facilitates the drying uniformity of the fish filaments.

[0036] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claimed rights.
