[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] like Figures 1 to 3 As shown, a squid drying device according to an embodiment of the present invention comprises a drying box 1, a feed port 11 is provided at one end of the drying box 1, a drying assembly is arranged inside the drying box 1; the drying assembly comprises an exhaust hood 23 arranged inside the drying box 1, a plurality of electric heating wires 24 are arranged at equal intervals inside the exhaust hood 23, an air pump 22 is arranged on one side of the exhaust hood 23, an exhaust pipe 222 is fixed to the exhaust port of the exhaust pump 22, and the other end of the exhaust pipe 222 is connected to the bottom end of the exhaust hood 23; a movable frame 3 is arranged above the electric heating wire 24, and a material turning assembly is arranged inside the movable frame 3;

[0034] When in use, the squid needs to be dried. Before the drying operation, the squid is placed inside the movable rack 3, and then the movable rack 3 is placed inside the drying box 1 through the feed port 11, and then the electric heating wire 24 is energized. After the electric heating wire 24 is energized, heat is generated, and the heat can dry the squid inside the movable rack 3. At the same time, the vacuum pump 22 is started to transport airflow to the exhaust pipe 222, and the airflow enters the exhaust hood 23 through the exhaust pipe 222. The exhaust hood 23 sprays the airflow, and the airflow contacts the electric heating wire 24 during the spraying process. At this time, the airflow takes away the heat on the surface of the electric heating wire 24, and then the airflow with heat is sprayed inside the movable rack 3, so that the squid inside the movable rack 3 can be dried. During the drying process, the squid is turned over by the turning component, so that the squid can be dried on both sides, and at the same time, the squid is prevented from being adhered to the inside of the movable rack 3 and being taken out to cause damage to the dried squid.

[0035] like Figures 1 to 3 As shown, the drying assembly also includes an air collecting hood 21 arranged above the mobile frame 3, the top of the air collecting hood 21 is fixedly connected to the top of the inside of the drying box 1, a circulation pipe 2 is fixed to the top of the drying box 1, the circulation pipe 2 is connected to the inside of the air collecting hood 21, and an air inlet pipe 221 is fixed to the air inlet of the air pump 22, and the other end of the air inlet pipe 221 is connected to one side of the bottom end of the circulation pipe 2;

[0036] During the drying process, the water inside the squid evaporates and a large amount of water vapor is generated. Directly discharging the water vapor to the outside will waste a lot of heat. Therefore, during the vacuum process of the vacuum pump 22, the air inside the circulation pipe 2 will be sucked into the air through the air inlet pipe 221. At this time, the inside of the circulation pipe 2 is in negative pressure. The circulation pipe 2 draws the air into the drying box 1 through the air collecting hood 21. At this time, the air collecting hood 21 can collect the gas after the squid is dried, so as to circulate the air inside the drying box 1. The circulation can retain part of the heat in the water vapor. At this time, lowering the temperature of the heating wire 24 can reduce the power consumption of the heating wire 24. At the same time, the internal air circulation of the drying box 1 can be realized to prevent the unclean external air from affecting the drying of the squid.

[0037] like Figure 3 to Figure 4 As shown, a filtrate cotton 25 is arranged at the bottom end of the circulation pipe 2, and the height of the filtrate cotton 25 is higher than the height of the air inlet pipe 221. A drainage port 251 is fixed at the bottom end of the circulation pipe 2 away from the feed port 11;

[0038] In the drying state, the interior of the drain port 251 is sealed. After the water vapor enters the interior of the circulation pipe 2, the water vapor contacts the filtrate cotton 25. The filtrate cotton 25 can absorb the moisture inside the water vapor. The air flow after absorption can be sucked by the air inlet pipe 221. After the filtrate cotton 25 absorbs the moisture, the moisture will drop to the position of the drain port 251 due to gravity. After use, the drain port 251 can be opened to discharge the moisture inside the filtrate cotton 25 to the outside.

[0039] like Figure 5 As shown, a motor 31 is installed at one end of the drying box 1 away from the feed port 11, a threaded rod 311 is fixed to the end of the rotating shaft of the motor 31, the threaded rod 311 runs through the interior of the drying box 1, and a threaded sleeve 312 is connected to the external thread of the threaded rod 311, and the top of the threaded sleeve 312 is fixedly connected to the end of the bottom of the moving frame 3 close to the motor 31;

[0040] When the movable rack 3 is taken out from the interior of the drying box 1, the surface temperature of the movable rack 3 is relatively high, and there is a certain risk in manually taking out the movable rack 3. Therefore, in the process of storing and retrieving the movable rack 3, the motor 31 is started to drive the threaded rod 311 to rotate, and the threaded rod 311 drives the threaded sleeve 312 to move. The threaded sleeve 312 drives the movable rack 3 to move, so that the movable rack 3 can automatically enter and exit the interior of the drying box 1 from the feed port 11, reducing manual operation.

[0041] like Figure 5 As shown, support bars 32 are provided on both sides below the mobile frame 3, the support bars 32 are fixedly connected to the inner wall of the drying box 1, and a slide column 321 is rotatably connected inside the support bars 32, and the top end of the slide column 321 is tightly attached to the bottom end of the mobile frame 3;

[0042] During the movement of the mobile frame 3, the support of the mobile frame 3 by the threaded sleeve 312 alone will not be stable enough. Therefore, the support bar 32 can support the bottom of the mobile frame 3 when the mobile frame 3 moves. At the same time, the sliding column 321 inside the support bar 32 can reduce the friction between the mobile frame 3 and the support bar 32, which can make the mobile frame 3 more stable during movement and fixation.

[0043] like Figures 6 to 9 As shown, the material turning assembly includes a second mesh plate 35 rotatably connected to the inside of the mobile frame 3, a first mesh plate 34 is arranged at one end of the second mesh plate 35 close to the rotating shaft thereof, the first mesh plate 34 is rotatably connected to the mobile frame 3, four groups of first mesh plates 34 and second mesh plates 35 are arranged at equal intervals, the ends of the two groups of first mesh plates 34 and second mesh plates 35 in the middle are fitted together, and the ends of the two groups of first mesh plates 34 and second mesh plates 35 at the two ends are fitted together with the inner wall of the mobile frame 3;

[0044] During use, the squids are evenly placed on the top of the second mesh plate 35. During the turning process, the squids on the top of the second mesh plate 35 are turned toward the top of the first mesh plate 34, so that the squids can be turned over and the squids can be less likely to stick to the surface.

[0045] like Figures 6 to 9As shown, a push rod 33 is provided on the side of the movable frame 3 away from the circulation pipe 2, and the push rod 33 is provided at an end close to the motor 31. A movable bar 331 is fixed to the end of the push rod 33 away from the motor 31, and a tooth 332 is fixed to the top of the movable bar 331. A first gear 344 is fixed to the end of the rotating shaft of the first mesh plate 34 close to the movable bar 331. The first gear 344 is meshed and connected with the movable bar 331 through the tooth 332. An active cavity matching the outer diameter of the movable bar 331 is provided inside the movable frame 3. Four groups of teeth 332 are provided, and the positions of the four groups of teeth 332 match the positions of the four groups of first mesh plates 34.

[0046] When the squid needs to be turned over, the motor 31 is started to drive the moving frame 3 to continue to move deeper into the drying box 1. At this time, the top rod 33 contacts the inner wall of the drying box 1. Under the action of the moving frame 3 continuing to move, the top rod 33 is pushed. At this time, the top rod 33 extends into the inside of the moving frame 3 to drive the moving bar 331 to move. At this time, the moving bar 331 drives the first gear 344 to turn over through the teeth 332, and the first gear 344 drives the first mesh plate 34 to turn over. At the same time, the first mesh plate 34 drives the third gear 351 to rotate through the second gear 345, and the third gear 351 drives the second mesh plate 35 to turn over in the direction of the first mesh plate 34. When the first mesh plate 34 and the second mesh plate 35 are turned over by nearly 90°, the undried side of the squid is attached to the surface of the first mesh plate 34. The undried side of the squid will also be dried to a small extent due to the heat inside the drying box 1, but the undried surface of the squid has a certain viscosity, which can enable the squid to adhere to the surface of the first mesh plate 34, so that the squid can switch the dried side.

[0047] like Figures 6 to 9 As shown, a second spring 333 is fixed to one end of the moving bar 331 away from the top rod 33, and one end of the second spring 333 away from the moving bar 331 is fixedly connected to the inner wall of the movable cavity of the moving frame 3;

[0048] The second spring 333 is squeezed during the movement of the moving bar 331. When the squid is turned over, the motor 31 drives the moving frame 3 to reset. At this time, the elastic force of the second spring 333 pushes the moving bar 331 to reset. During the reset process, the first gear 344 can be driven by the teeth 332 to rotate in the opposite direction. At this time, the first mesh plate 34 and the second mesh plate 35 can be reversed and reset.

[0049] like Figures 6 to 9As shown, a metal pull rod 343 is provided above the second mesh plate 35, and second pull ropes 341 are fixed on both sides of the metal pull rod 343, and the bottom end of the second pull rope 341 is fixedly connected to the top of the first mesh plate 34, and the second pull rope 341 is provided on both sides of the top of the first mesh plate 34 away from its rotating shaft, and the rotating shafts on both sides inside the movable frame 3 are connected with pulleys 342, and the second pull rope 341 is wound around the outside of the pulley 342, and a placement groove 352 is provided inside the second mesh plate 35, and one end of the placement groove 352 away from its rotating shaft is rotatably connected with a flip shaft 353, and a pull plate 354 is fixed on the top of the flip shaft 353, and an elastic plate 355 is provided inside the placement groove 352, and one end of the elastic plate 355 is fixedly connected to the flip shaft 353, and a hook facing the elastic plate 355 is provided on the top of the pull plate 354;

[0050] Part of the squid will have adhered to the surface of the second mesh plate 35 during the drying process. During the flipping of the first mesh plate 34, one end of the second pull rope 341 will be driven to move upward. At this time, the gravity of the metal pull rod 343 will drive the other end of the second pull rope 341 to move downward. The pulley 342 can guide the movement of the second pull rope 341. At the same time, during the flipping of the second mesh plate 35, the pull plate 354 will be flipped. When the second mesh plate 35 and the first mesh plate 34 are close to each other, the hook of the pull plate 354 will hook the metal pull rod 343. When the first mesh plate 34 and the second mesh plate 35 are flipped and separated, the first mesh plate 34 with The second pull rope 341 is driven, and the second pull rope 341 pulls the metal pull rod 343 to rise, and the metal pull rod 343 drives the pull plate 354 to flip over, and the pull plate 354 drives the elastic plate 355 to flip out from the inside of the placement groove 352 through the flip shaft 353. At this time, the elastic plate 355 can push down the squid adhered to the surface of the second mesh plate 35. Because the elastic plate 355 is elastic, it can be deformed during the pushing process, so that the squid can better fit the surface of the first mesh plate 34. The pull plate 354 is elastic. After the metal pull rod 343 pulls the pull plate 354 to deform to a certain extent, the pull plate 354 and the metal pull rod 343 are separated.

[0051] like Figure 2 and Fig.10 As shown, a door panel 12 is hingedly connected to the upper part of the feed port 11, and first pull ropes 121 are fixed to both sides of the bottom end of the door panel 12, and a fixing block 122 is fixed to one end of the first pull rope 121 away from the door panel 12, and a first spring 123 is sleeved on the outside of the first pull rope 121, and one end of the first spring 123 is fixedly connected to the fixing block 122, and a sliding hole matching the outer diameter of the fixing block 122 is provided inside the drying box 1, and the fixing block 122 forms a sliding structure inside the sliding hole of the drying box 1, and one end of the first spring 123 away from the fixing block 122 is fixedly connected to the sliding hole of the drying box 1;

[0052] When the movable frame 3 extends out from the feed port 11, the side plate of the movable frame 3 lifts up the door panel 12. During the flipping process of the door panel 12, the first pull rope 121 is pulled. The first pull rope 121 drives the first spring 123 to be compressed through the fixed block 122. At this time, the side plate of the movable frame 3 supports the door panel 12. After the movable frame 3 enters the interior of the drying box 1, the door panel 12 loses its support. At this time, the elastic force of the first spring 123 drives the first pull rope 121 to pull back the door panel 12. The door panel 12 can be flipped back to the interior of the feed port 11, and the drying box 1 can be sealed to prevent impurities from entering the interior of the drying box 1 during the drying process.
