Description

Technical Field

[0001] This application relates to the technical field of fish maw processing, and in particular to a fish maw soaking device for processing ready-to-eat fish maw. Background Technology

[0002] The core process of ready-to-eat fish maw processing is as follows: Dried fish maw is first sorted to remove impurities, then pre-treated by low-temperature secondary soaking or microwave puffing combined with soaking process, during which temperature is continuously controlled and water is changed regularly; after soaking, it is cleaned to remove oil and impurities, then steamed and shaped, and flavored with auxiliary ingredients (such as red dates and milk), and finally aseptically filled, sterilized at high temperature, cooled and packaged to complete the finished product production.

[0003] Soaking is a crucial step: first, it allows the dried fish maw to fully absorb water and swell, restoring its soft and chewy texture and preventing the finished product from becoming dry and hard; second, it dissolves some soluble fishy substances, reducing the fishy smell and improving the eating experience; and third, it softens impurities on the surface and inside the fish maw, making it easier to remove during subsequent cleaning and ensuring the product's cleanliness. Currently, the industry generally uses a static soaking process, employing a constant-temperature, static soaking tank, combined with electric heating and temperature sensors to ensure a suitable soaking environment.

[0004] Using a static soaking tank means that impurities such as bloodstains, grease, and mud on the fish maw cannot be removed during the soaking stage as they rely entirely on subsequent cleaning. Utility Model Content

[0005] In order to remove easily detachable impurities during the initial soaking stage of fish maw, this application provides a fish maw soaking device for processing ready-to-eat fish maw.

[0006] The ready-to-eat fish maw soaking device provided in this application adopts the following technical solution: A soaking device for ready-to-eat fish maw processing includes a soaking tank, which is rotatably mounted on a support platform. The top of the soaking tank is open, and a stirring device is mounted on the support platform. The stirring device includes a stirring rod, a drive motor, and a turntable gear. The drive motor is fixed on the support platform and drives the turntable gear to rotate. The stirring rod is an inverted U-shape, with one end rotatably connected to the non-center part of the side wall of the turntable gear, and the rotation shaft is set in the horizontal direction. The other end of the stirring rod is located inside the soaking tank and is fixed with a crossbar, which is also set in the horizontal direction.

[0007] By adopting the above technical solution, when the drive motor rotates the turntable gear, the stirring rod, due to its rotational connection with the off-center part of the turntable gear at one end, forms a circumferential motion trajectory, which in turn drives the crossbar to perform a circular stirring motion within the soaking tank. This motion breaks the limitations of static soaking, allowing the fish maw to fully contact the soaking water, while simultaneously generating a gentle water flow impact that removes easily detachable impurities such as blood and grease from the surface of the fish maw. This achieves simultaneous soaking and preliminary impurity removal, improving processing efficiency and the cleanliness of the fish maw.

[0008] Optionally, telescopic tubes are fitted at both ends of the crossbar, and the telescopic tubes slide back and forth along the length of the crossbar. The ends of the telescopic tubes away from the crossbar are rotatably connected to ball bearings, and the inside of the telescopic tubes is filled with elastic blocks. Multiple paddles are fixed on the outer wall of the crossbar, and adjacent paddles are spaced apart along the length of the crossbar.

[0009] By adopting the above technical solution, the telescopic tube can adaptively extend and retract according to the shape of the soaking tank. That is, the soaking tank is cylindrical, the ball bearings reduce frictional damage between the telescopic tube and the inner wall of the soaking tank, the elastic block provides buffer for extension and retraction, so that the ball bearings can always abut against the inner wall of the soaking tank, providing stable limiting support for the stirring rod; the paddle on the crossbar enhances the water flow disturbance effect during stirring, which not only ensures that the fish maw absorbs water evenly, but also further removes impurities, while not damaging the collagen structure of the fish maw, thus ensuring the soaking quality.

[0010] Optionally, a speed-changing gear is rotatably mounted on the support platform, which meshes with the turntable gear, and the drive motor drives the speed-changing gear to rotate.

[0011] By adopting the above technical solution, the speed-changing gear can adjust the rotation speed of the turntable gear, thereby controlling the oscillation frequency of the stirring rod, adapting to the soaking requirements of dried fish maw of different specifications. For thin fish maw, the frequency can be reduced to avoid over-stirring and damage; for thick fish maw, the frequency can be increased to improve the impurity removal efficiency and enhance the versatility of the device.

[0012] Optionally, a worm gear is fixed to the rotating end of the drive motor, and a worm wheel is provided between the bottom of the soaking tank and the support platform. The worm wheel is rotatably mounted on the support platform and fixedly connected to the soaking tank, and the worm gear meshes with the worm wheel. A rotating shaft is fixed at the center of the speed-changing gear, and a belt is looped between the worm gear and the rotating shaft. The belt is in a taut state.

[0013] By adopting the above technical solution, when the drive motor is running, the worm gear drives the transmission gear to rotate via the belt, while simultaneously meshing with the worm wheel to drive the soaking tank to rotate horizontally. The reverse motion of the soaking tank and the stirring rod creates a relative shear water flow, which significantly improves the contact efficiency between the fish maw and the water. Impurities are more easily removed in the bidirectional disturbance, and local accumulation of fish maw can be avoided, ensuring that each piece of fish maw is soaked evenly, further optimizing the initial impurity removal effect.

[0014] Optionally, a hinge seat is provided on one side of the bottom of the support platform, the top of the hinge seat is hinged to the support platform and the hinge axis is set in the horizontal direction, and a hydraulic cylinder is provided on the other side of the bottom of the support platform, one end of the hydraulic cylinder body is hinged to the ground and the piston end of the hydraulic cylinder is hinged to the bottom surface of the support platform; the hydraulic cylinder is located below the stirring device.

[0015] By adopting the above technical solution, the hydraulic cylinder can extend and retract to drive the bearing platform to rotate around the hinge seat, which facilitates the quick dumping of wastewater and impurities after soaking, reducing manual cleaning costs; at the same time, the rotation angle is adjustable to adapt to different unloading needs, avoiding the impact of residual wastewater and impurities in the soaking tank on the next batch of processing, and improving the practicality of the device.

[0016] Optionally, a grate is slidably mounted on the soaking tank, and the grate has elongated holes. The length of the elongated holes is along the horizontal swing path of the stirring rod. A slider and corrugated strips are mounted on the grate. The slider is slidably mounted on the elongated holes and slides back and forth along the length of the elongated holes. Two corrugated strips are provided and symmetrically distributed on both sides of the slider. One end of the corrugated strip is fixed to the slider, and the other end is fixed to the corresponding end of the elongated hole. The corrugated strips cooperate with the slider to cover the elongated holes. The stirring rod passes through the slider and slides vertically with the slider.

[0017] By adopting the above technical solution, the grate can limit the position of the fish maw, preventing it from floating and not being fully soaked during stirring; the slider slides along the long hole as the stirring rod swings, and the corrugated strip extends and retracts synchronously to always cover the long hole, preventing the fish maw from coming out of the long hole; the stirring rod and the slider slide in a vertical direction without affecting the up and down adjustment of the grate, ensuring that the fish maw is always pressed into the water, thus guaranteeing the soaking effect.

[0018] Optionally, an adjustment plate is fixed to the edge of the grate. Two adjustment plates are provided and symmetrically distributed on the edge of the grate. The adjustment plates are inverted L-shaped. A servo motor is fixed to the outer wall of the soaking tank. A screw is fixed to the rotating end of the servo motor. The screw is arranged vertically and passes through the end of one of the adjustment plates that protrudes from the edge of the cover plate. A guide rod is fixed to the outer wall of the soaking tank. The guide rod and the screw are symmetrically arranged on the outer wall of the soaking tank. The guide rod passes through the other adjustment plate and slides vertically with the corresponding adjustment plate.

[0019] By adopting the above technical solution, the servo motor drives the screw to rotate, which in turn moves the adjustment plate vertically, thereby adjusting the height of the grate. The grate position can be flexibly adjusted according to the degree of soaking and the height of the fish maw, always maintaining a pressing effect on the fish maw to prevent it from floating, while not affecting the swing of the stirring rod and the disturbance of the water flow, thus balancing the uniformity of soaking and the stability of the positioning.

[0020] Optionally, the soaking tub is connected to an inlet pipe and an outlet pipe.

[0021] By adopting the above technical solution, the inlet pipe can quickly inject temperature-controlled soaking water, and the outlet pipe facilitates the periodic discharge of wastewater containing impurities, enabling convenient replacement of the soaking water. The continuously changing clean water can promptly remove impurities and soluble fishy-smelling substances, maintaining the cleanliness of the soaking environment, further reducing the fishy smell of the fish maw, and laying a good foundation for subsequent processing.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By coordinating the movement of the stirring device and the soaking tank, soaking and preliminary impurity removal are carried out simultaneously, effectively removing easily detachable impurities such as bloodstains and grease from the surface of the fish maw, reducing the pressure of subsequent cleaning, and improving processing efficiency and product cleanliness; 2. It has adaptive adjustment capabilities, which can be adapted to the soaking requirements of different sizes of fish maw through the variable speed gear, and the height of the grate can be adjusted to prevent the fish maw from floating, so as to balance the uniformity of soaking and the integrity of the fish maw structure, and ensure the quality of soaking. 3. It integrates convenient functions such as water inlet, drainage, and tipping unloading, simplifying the operation process, reducing labor costs, while maintaining a clean soaking environment, further reducing the fishy smell of fish maw, and improving the product's eating experience.

[0025] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0026] This application discloses a fish maw soaking device for processing ready-to-eat fish maw, which aims to solve the problem that traditional static soaking tanks cannot initially remove impurities during the soaking stage, and to achieve simultaneous soaking and initial impurity removal of fish maw.

[0027] refer to Figure 1 The ready-to-eat fish maw processing soaking device includes a soaking tank 1, a support platform 2, and a stirring device 3. The soaking tank 1 is cylindrical with an open top, and its outer wall is connected to an inlet pipe 11 and an outlet pipe 12. The inlet pipe 11 is used to inject soaking water at a preset temperature, and the outlet pipe 12 is used to discharge wastewater containing impurities. Both the inlet pipe 11 and the outlet pipe 12 are equipped with valves to control the flow. The soaking tank 1 is rotatably mounted on the support platform 2.

[0028] refer to Figure 1 , Figure 2 and Figure 3 The support platform 2 is equipped with a stirring device 3, a worm gear 23, and a worm 22. The stirring device 3 includes a stirring rod 31, a drive motor 32, and a turntable gear 33. The stirring rod 31 has an inverted U-shaped structure. One end of the rod is rotatably connected to the non-center part of the side wall of the turntable gear 33 via a horizontally set rotating shaft. The other end extends into the interior of the soaking tank 1 and is fixed with a crossbar 34. The crossbar 34 is set horizontally and perpendicular to the axis of the soaking tank 1. The worm gear 23 is fixed to the bottom of the soaking tank 1 and is rotatably connected to the support platform 2. The worm gear 23 meshes with the worm 22 set on the support platform 2. The end of the worm 22 away from the worm gear 23 is fixedly connected to the rotating end of the drive motor 32. The drive motor 32 is fixed to the side wall of the support platform 2 by bolts.

[0029] refer to Figure 1 and Figure 2 A speed-changing gear 21 is rotatably mounted on the support platform 2. A rotating shaft is fixed at the center of the speed-changing gear 21. A tensioned belt 24 is looped between the rotating shaft and the worm gear 22, so that the drive motor 32 can drive the speed-changing gear 21 to rotate through the belt 24 when it is running. The speed-changing gear 21 meshes with a turntable gear 33, which is located above the support platform 2. In this embodiment, there are two turntable gears 33 arranged vertically and meshing with each other. The speed-changing gear 21 meshes with only one of the turntable gears 33. A pulley for use with the belt 24 is provided between the rotating shaft at the center of the speed-changing gear 21 and the end of the worm gear 22.

[0030] refer to Figure 1 and Figure 3 Both ends of the crossbar 34 are fitted with telescopic tubes 4, which can slide back and forth along the length of the crossbar 34. The telescopic tubes 4 are filled with elastic blocks 42, preferably made of rubber, and their two ends abut against the ends of the crossbar 34 and the inner wall of the telescopic tubes 4, respectively. The ends of the telescopic tubes 4 away from the crossbar 34 are rotatably connected with ball bearings 41, which roll in contact with the inner wall of the soaking tank 1. Under the elastic force of the elastic blocks 42, the ball bearings 41 always abut against the inner wall of the soaking tank 1, providing stable limiting support for the stirring rod 31. At the same time, multiple blades are fixed on the outer wall of the crossbar 34. Adjacent blades are evenly spaced along the length of the crossbar 34 and are inclined to enhance the water flow disturbance effect during stirring.

[0031] refer to Figure 1 and Figure 2A grating 5 is slidably mounted on the soaking tank 1. The grating 5 is circular and matches the inner diameter of the soaking tank 1. The grating 5 has elongated holes 51, the length of which follows the horizontal swing path of the stirring rod 31. A slider 52 and corrugated strips 53 are mounted on the grating 5. The slider 52 is slidably embedded in the elongated holes 51 and can slide back and forth along the length of the holes 51. Two corrugated strips 53 are symmetrically distributed on both sides of the slider 52. The corrugated strips 53 are made of elastic waterproof material, with one end fixedly connected to the side wall of the slider 52 and the other end fixedly connected to the corresponding end of the elongated hole 51. This allows the corrugated strips 53 to extend and retract synchronously when the slider 52 slides, always cooperating with the slider 52 to cover the elongated holes 51 and prevent the fish maw from detaching from them. The stirring rod 31 passes through the slider 52, and the stirring rod 31 and the slider 52 are in a sliding fit along the vertical direction, which does not affect the up and down movement of the grate 5.

[0032] refer to Figure 1 and Figure 2 Two symmetrically distributed adjusting plates 6 are fixed to the edge of the grate 5. The adjusting plates 6 are inverted L-shaped, with their horizontal sections protruding from the edge of the grate 5. A servo motor 61 is fixed to the outer wall of the soaking tank 1 via a bracket. A vertically oriented screw 62 is fixed to the rotating end of the servo motor 61. The screw 62 passes through the horizontal section of one of the adjusting plates 6 and is threadedly connected to the adjusting plate 6. A guide rod 63 is also fixed to the outer wall of the soaking tank 1. The guide rod 63 is symmetrically arranged with the screw 62 and passes through the horizontal section of the other adjusting plate 6, slidingly engaging with the adjusting plate 6 in the vertical direction. This allows the adjusting plate 6 to move vertically when the servo motor 61 drives the screw 62 to rotate, thereby adjusting the height of the grate 5.

[0033] refer to Figure 1 and Figure 2 A hinge seat 25 is provided on one side of the bottom of the support platform 2. The hinge seat 25 is fixed to the ground by expansion bolts. Its top is hinged to the bottom surface of the support platform 2 by a horizontal hinge shaft. A hydraulic cylinder 26 is provided on the other side of the bottom of the support platform 2. One end of the body of the hydraulic cylinder 26 is hinged to the ground, and the piston end of the hydraulic cylinder 26 is hinged to the bottom surface of the support platform 2. The hydraulic cylinder 26 is located below the stirring device 3. The extension and retraction of the hydraulic cylinder 26 can drive the support platform 2 to rotate around the hinge seat 25, which is convenient for pouring out wastewater and impurities after soaking.

[0034] The implementation principle of the ready-to-eat fish maw soaking device in this embodiment is as follows: In use, firstly, according to the specifications of the fish maw to be processed, the rotation speed of the turntable gear 33 is adjusted via the speed-changing gear 21, thereby setting the oscillation frequency of the stirring rod 31. Then, the dried fish maw is placed into the soaking tank 1, and soaking water at a preset temperature is injected through the water inlet pipe 11. The servo motor 61 is started, driving the screw 62 to rotate to adjust the height of the grate 5, so that the grate 5 presses down on the fish maw to prevent it from floating. The drive motor 32 is started, driving the worm gear 22 to rotate. The worm gear 22 meshes with the worm wheel 23 to drive the soaking tank 1 to rotate, and on the other hand, it drives the speed-changing gear 21 to rotate via the belt 24. The speed-changing gear 21 meshes with the turntable gear 33 to drive the turntable gear 33 to rotate, thereby causing the stirring rod 31 to oscillate around the center of the turntable gear 33, driving the crossbar 34 to perform an arc-shaped stirring motion within the soaking tank 1. The paddles on the crossbar 34 enhance water flow disturbance, ensuring full contact between the fish maw and the soaking water. Simultaneously, the telescopic tube 4 adapts to the movement of the elastic block 42, and the ball bearing 41 rolls against the inner wall of the soaking tank 1, providing support for the stirring rod 31 and reducing friction damage. Easily detachable impurities on the surface of the fish maw are removed by the water flow and periodically discharged with the wastewater through the outlet pipe 12. During soaking, the height of the grate 5 can be adjusted in real-time by the servo motor 61 according to the degree of expansion of the fish maw, maintaining consistent pressure on the fish maw. The slider 52 slides along the elongated hole 51 as the stirring rod 31 swings, and the corrugated strip 53 synchronously extends and retracts to cover the elongated hole 51, preventing the fish maw from falling out. After soaking, the drive motor 32 is turned off, the outlet pipe 12 is opened to discharge wastewater, and then the hydraulic cylinder 26 is activated to drive the support platform 2 to tilt, dumping the soaked fish maw and residual impurities into the subsequent cleaning process, completing the soaking operation.

[0035] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
