Description

Technical Field

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

[0002] Currently available ready-to-eat fish maw requires soaking dried fish maw during production. This soaking process uses soaking equipment, which is time-consuming. Prolonged soaking may increase the risk of nutrient loss. Furthermore, static soaking can lead to uneven soaking due to the accumulation of fish maw in certain areas. Utility Model Content

[0003] The purpose of this utility model is to provide a soaking device for ready-to-eat fish maw, so as to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: This utility model provides a soaking device for ready-to-eat fish maw, comprising: The pot body has a rotating shaft at the center of the bottom of the inner cavity. One end of the rotating shaft passes through the bottom wall of the pot body and is connected to the output shaft of the rotary motor. The other end is provided with a limiting ring. The outer wall of the rotating shaft is provided with a sliding groove along the axial direction of the rotating shaft. A rotating ring is sleeved on the rotating shaft. The inner wall of the rotating ring is provided with a protrusion, which cooperates with the sliding groove. A spring is provided between the rotating ring and the bottom wall of the pot body. The spring is sleeved on the rotating shaft. At least two torque sleeves extend laterally from the rotating ring. Torsion springs are provided inside the torque sleeves. A swing mechanism has a rotating shaft, a swing seat, and a swing blade. One end of the rotating shaft is rotatably mounted in the torque sleeve and connected to the torsion spring. The swing seat is fixedly connected to the other end of the rotating shaft, and the swing blade is mounted on the swing seat. A pot lid is placed on top of the pot body. A telescopic rod is provided at the center of the pot body, one end of which is connected to a telescopic motor on the pot lid, and the other end is provided with a flexible pressure plate. An avoidance hole is provided at the center of the flexible pressure plate.

[0005] This invention utilizes a rotating shaft with oscillating blades to ensure thorough contact between the fish maw and water, preventing insufficient or excessive soaking in certain areas. This avoids uneven soaking or spoilage in the center caused by fish maw piling up. Simultaneously, the flexible pressure plate accelerates water penetration and impurity removal. After pressure, the oscillating blades return to their original position and continue stirring, promoting fish maw expansion and shortening soaking time. To further improve soaking efficiency, during the soaking process, the telescopic motor on the lid extends and retracts, causing a telescopic rod to push the flexible pressure plate downwards, squeezing the fish maw in the water, accelerating water penetration and impurity removal, and promoting fish maw expansion.

[0006] During operation, when the telescopic motor drives the flexible pressure plate to press down (during the pressing process, the rotary motor stops working and keeps the swing blade static), it first contacts the tip of the swing blade. The swing blade is normally set in a non-vertical position, that is, the swing blade is set at an angle. At this time, the flexible pressure plate will press down the swing blade so that it rotates around the axis of rotation along the angle. During the pressing process, the water under the flexible pressure plate can flow through the clearance hole.

[0007] As the pressure continues to the limit ring position, the oscillating blade rotates around the axis of the rotating shaft to the horizontal arrangement device. During this rotation process, the torsion spring of the torsion sleeve, due to the clearance hole of the flexible pressure plate, allows the flexible pressure plate to pass over the limit ring and continue to press down. When it comes into contact with the rotating ring, it will push the rotating ring to slide downward. With the limiting of the sliding groove and the protrusion, the rotating ring slides down along the axial direction of the rotating shaft, providing the pressure space for the flexible pressure plate to compress the fish maw, accelerating the penetration of water and the removal of impurities, and promoting the expansion of the fish maw.

[0008] After the squeezing action is completed, the telescopic motor controls the telescopic rod to retract, the flexible pressure plate moves up, the rotating ring resets under the action of the spring, and the swing blade resets under the action of the torsion spring. During the reset process of the swing blade, the squeezed fish maw is stirred again, which can effectively disperse the squeezed and stacked fish maw and accelerate the penetration of water.

[0009] In this embodiment, the rotating shaft drives the oscillating blades to stir, ensuring that the fish maw and water come into full contact. This avoids insufficient or excessive soaking in certain areas and prevents uneven soaking or spoilage of the central part of the fish maw due to stacking. At the same time, the squeezing of the flexible pressure plate accelerates water penetration and the removal of impurities. After squeezing, the oscillating blades return to their original position and stir, promoting the expansion of the fish maw and shortening the soaking time.

[0010] As an extension of the above solution, the oscillating blade is inclined when the torsion spring is not under stress, with the blade surface of the oscillating blade at an angle to the vertical plane. This inclined arrangement allows the oscillating blade to be compressed by the flexible pressure plate, which is then converted into rotational force on the rotating shaft. Under the action of the rotating shaft, the oscillating blade tends to be arranged horizontally, providing compression space for the flexible pressure plate.

[0011] As an extension of the above solution, the flexible pressure plate is connected to the telescopic rod via a connecting frame. The diameter of the clearance hole is larger than the outer diameter of the limiting ring but smaller than the outer diameter of the rotating ring. The clearance hole is larger than the limiting ring, allowing it to avoid interference during the downward pressing of the flexible pressure plate. Simultaneously, its smaller size allows the flexible pressure plate to push the rotating ring and the oscillating blade downwards.

[0012] As an extension of the above solution, the flexible pressing plate is provided with several drainage holes. The drainage holes make the extrusion process of the flexible pressing plate smoother, and at the same time, the air inside the fish maw can be quickly discharged through the drainage holes in the initial stage of extrusion, avoiding the pressure surge caused by the airtight chamber effect and reducing the risk of the fish maw being squeezed and broken.

[0013] As an extension of the above solution, the swing seat is provided with a swing shaft, and a swing window is provided on the side away from the rotation shaft. One end of the swing blade passes through the swing window and is fixedly connected to the swing shaft. The swing window can provide the swing blade with the swing direction of movement, and when the rotation shaft rotates, the swing blade tilts backward due to the action of the swing window. The movement trajectory of the backward-tilted blade has a gentler force on the fish maw.

[0014] As an extension of the above solution, the width of the swing window is greater than the thickness of the swing blade, and the two sides of the swing window in the width direction are symmetrically arranged about the axis of the swing shaft. The symmetrical arrangement of the two sides of the swing window ensures that the swing blade maintains the same backward tilt angle when the rotation axis rotates in the forward or reverse direction. The backward tilting blade can protect the integrity of the fish maw during rotation and avoid damage caused by traditional vigorous stirring.

[0015] As an extension of the above solution, the oscillating blade is a flexible blade in the shape of a biomimetic fin. The flexible blade, in the form of a biomimetic fin, can generate a gentle water flow during oscillation, propelling the fish maw to slowly turn over, avoiding the physical damage that may be caused by mechanical stirring blades.

[0016] As an extension of the above solution, the pot body is provided with a jacket, and the jacket is provided with a steam pipe for connecting to an external steam heating device. This extended solution heats the water in the jacket layer by introducing steam into it, which is then conducted to the soaking liquid through the pot body. The increased temperature accelerates the diffusion rate of water molecules, causing the collagen in the fish maw to absorb water and swell, thus shortening the soaking time.

[0017] As an extension of the above solution, the pot body is equipped with a water inlet pipe and a drain pipe. The water inlet pipe is located on the upper side of the pot body, and the drain pipe is located at the bottom of the pot body. The drain pipe and the water inlet pipe can be used to change the water midway to remove fishy smells and impurities. During the soaking process of fish maw, impurities such as oil, blood, and mucus will be released. The old liquid is discharged through the drain pipe, and new water is injected through the water inlet pipe, which can improve the cleanliness.

[0018] As an extension of the above solution, a liquid level sensor is installed inside the pot. The sensor monitors the water level in real time. When the injected water reaches a set value, it automatically triggers the valve in the water inlet pipe to close, avoiding errors caused by manual estimation. Simultaneously, it dynamically monitors changes in the liquid level during soaking. As the fish maw absorbs water and expands during soaking, the liquid level will drop. The sensor tracks these changes in real time, and if the liquid level falls below a threshold, it automatically adds water to maintain a surface covering the fish maw, preventing uneven soaking caused by localized exposure.

[0025] Reference Figures 1 to 3 The following are several embodiments of a soaking device for ready-to-eat fish maw according to this utility model.

[0026] like Figure 1 and Figure 2 As shown, in some embodiments, a soaking device for ready-to-eat fish maw includes: The pot body 100 has a rotating shaft 110 located at the center of the bottom of the inner cavity. One end of the rotating shaft 110 passes through the bottom wall of the pot body and is connected to the output shaft of the rotary motor 120. The other end is provided with a limiting ring 130. The outer wall of the rotating shaft 110 is provided with a sliding groove 140 along the axial direction of the rotating shaft 110. A rotating ring 200 is sleeved on the rotating shaft 110. The inner wall of the rotating ring 200 is provided with a protrusion 210, which cooperates with the sliding groove 140. A spring member 220 is provided between the rotating ring 200 and the bottom wall of the pot body 100. The spring member 220 is sleeved on the rotating shaft 110. At least two torque sleeves 230 extend laterally from the rotating ring 200, and torsion springs are provided inside the torque sleeves 230. The swing mechanism 300 has a rotating shaft 310, a swing seat 320 and a swing blade 330. One end of the rotating shaft 310 is rotatably mounted in the torque sleeve 230 and connected to the torsion spring. The swing seat 320 is fixedly connected to the other end of the rotating shaft 310. The swing blade 330 is mounted on the swing seat 320. A pot lid 400 is placed on top of the pot body 100. A telescopic rod 410 is provided at the center of the pot body 100. One end of the telescopic rod 410 is connected to a telescopic motor 420 provided on the pot lid 400, and the other end is provided with a flexible pressure plate 430. An avoidance hole 440 is provided at the center of the flexible pressure plate 430.

[0027] This embodiment utilizes the agitation of the oscillating blades on a rotating shaft to ensure full contact between the fish maw and water, preventing insufficient or excessive soaking in certain areas. This avoids uneven soaking or spoilage in the center of the fish maw due to stacking. Simultaneously, the pressure of the flexible plate accelerates water penetration and impurity removal. After pressure, the repositioning and agitation of the oscillating blades further promotes the expansion of the fish maw and shortens the soaking time. The flexible material of the flexible pressure plate and / or flexible blades in this invention possesses elasticity and flexibility, including one or more combinations of silicone, polyurethane, and rubber.

[0028] To further improve the soaking efficiency, during the soaking process, the telescopic motor on the pot lid extends and retracts, causing the telescopic rod to push the flexible pressure plate downwards, squeezing the fish maw in the water. The periodic movement of the telescopic motor, with a telescopic frequency of 5-10 times per minute, squeezes the fish maw to accelerate water penetration and impurity removal, promoting the expansion of the fish maw.

[0029] In this embodiment, when the telescopic motor drives the flexible pressure plate to press down (during the pressing process, the rotary motor stops working, keeping the swing blade static), it first contacts the apex of the swing blade. The swing blade is normally set in a non-vertical position, that is, the swing blade is set at an angle. At this time, the flexible pressure plate will press down the swing blade so that it rotates around the axis of the rotating shaft along the inclined direction. When it continues to press down to the position of the limit ring, the swing blade rotates around the axis of the rotating shaft to the horizontal arrangement device. During this rotation process, the torsion spring of the torsion sleeve, due to the clearance hole of the flexible pressure plate, can pass the limit ring and continue to press down. When it abuts against the rotating ring, it will push the rotating ring to slide down. With the limit of the sliding groove and the protrusion, the rotating ring slides down along the axis of the rotating shaft, providing the squeezing space for the fish maw for the pressing down of the flexible pressure plate, accelerating the penetration of water and the removal of impurities, and promoting the expansion of the fish maw.

[0030] Once the pressure is applied to the set position (which is determined by the amount of foamed gelatin and can be set by controlling the stroke of the telescopic motor and telescopic rod), the telescopic motor controls the telescopic rod to retract, the flexible pressure plate to move upward, the rotating ring to reset under the action of the spring, and the oscillating blade to reset under the action of the torsion spring. During the resetting process of the oscillating blade, the squeezed gelatin is agitated again, effectively dispersing the squeezed and stacked gelatin and accelerating moisture penetration. In some specific embodiments, during the two squeezing processes, the rotating motor is activated to use the rotation of the oscillating blade to disperse the squeezed gelatin, which can effectively promote the expansion of the gelatin and improve the soaking efficiency.

[0031] This embodiment uses a rotating shaft to agitate the fish maw, ensuring full contact with water and preventing insufficient or excessive soaking in certain areas. This also avoids uneven soaking or spoilage in the center of the fish maw due to stacking. At the same time, the pressure of the flexible plate accelerates water penetration and the removal of impurities. After the pressure is applied, the repositioning and agitation of the oscillating blades promote the expansion of the fish maw and shorten the soaking time.

[0032] like Figure 2 As shown, in some embodiments, the oscillating blade 330 is inclined when the torsion spring is not under stress, with the blade surface of the oscillating blade 330 at an angle to the vertical plane. This inclined arrangement allows it to tilt upwards and push the water flow during rotation, and to tilt downwards and push the water flow in the opposite direction. Because the oscillating blade is positioned downwards, the water flow can impact the wall of the pot, increasing the water flow disturbance and using the water flow to wash away impurities, rinse the surface of the fish maw, and remove blood, salt, and mucus. At the same time, this inclined arrangement allows the force of the oscillating blade under the pressure of the flexible pressure plate to be converted into the rotational force of the rotating shaft. Under the action of the rotating shaft, the oscillating blade tends to be arranged horizontally, providing compression space for the flexible pressure plate.

[0033] like Figure 1 and Figure 3 As shown, in some embodiments, the flexible pressure plate 430 is connected to the telescopic rod via a connecting frame 431. The diameter of the clearance hole 440 is larger than the outer diameter of the limiting ring 130 and smaller than the outer diameter of the rotating ring 200. The clearance hole is larger than the size of the limiting ring, allowing it to avoid interference during the downward pressing of the flexible pressure plate. Simultaneously, its smaller size allows the flexible pressure plate to push the rotating ring and the oscillating blade downwards.

[0034] like Figure 3 As shown, in some embodiments, the flexible pressure plate 430 is provided with a plurality of drainage holes 432. The drainage holes make the extrusion process of the flexible pressure plate smoother, especially suitable for uniform force distribution on thin fish maw (thickness < 3 mm). At the same time, in the initial stage of extrusion, the air inside the fish maw can be quickly discharged through the drainage holes, avoiding a sudden increase in pressure due to the airtight chamber effect and reducing the risk of the fish maw being squeezed out.

[0035] like Figure 2 As shown, in some embodiments, the swing seat 320 is provided with a swing shaft 331, and a swing window 321 is provided on the side away from the rotation shaft 310. One end of the swing blade 330 passes through the swing window 321 and is fixedly connected to the swing shaft 331.

[0036] In this embodiment, the swing window provides the swing direction for the swing blades. When the rotation axis rotates, the swing blades tilt backward due to the swing window, forming a certain backward tilt angle with the direction of rotation. The backward-tilted blades exert a gentler force on the fish maw. If the blades were vertical or tilted forward, rotation could generate significant shear or impact forces on the fish maw, especially when it becomes soft after absorbing water and swelling, easily leading to breakage or shape damage. The backward-tilted blades guide the liquid flow through their tilt angle, causing the fish maw to "passively tumble" with the water flow, rather than being directly impacted or squeezed by the blades.

[0037] In some specific embodiments, the width of the swing window is greater than the thickness of the swing blade, and the two sides of the swing window in the width direction are symmetrically arranged about the axis of the swing shaft. The symmetrical arrangement of the two sides of the swing window ensures that the swing blade maintains the same backward tilt angle when the rotation axis rotates in the forward or reverse direction. The backward tilting blade can protect the integrity of the fish maw during rotation and avoid damage caused by traditional vigorous stirring, which is especially suitable for ready-to-eat fish maw products with high requirements for appearance quality.

[0038] In some specific embodiments, the oscillating blade is a flexible blade resembling a biomimetic fin. The flexible blade, with its biomimetic fin shape, generates a gentle water flow during oscillation, slowly agitating the fish maw and avoiding physical damage that might be caused by mechanical stirring blades. The biomimetic fin structure, with its convex upper and lower ends and concave center, ensures that if there is excessively concentrated fish maw on the front side of the fin in the direction of rotation, some of the fish maw is squeezed to the rear along the concave center during rotation, preventing excessive compression and damage to the front side.

[0039] like Figure 1 As shown, in some embodiments, the pot body 100 is provided with a jacket 150, the jacket 150 is provided with a steam pipe 160, and the steam pipe 160 is used to connect to an external steam heating device.

[0040] In this embodiment, steam is introduced into the jacket to heat the water in the jacket layer (typically controlled between 40 and 80 degrees Celsius, depending on the type of fish maw), which is then conducted to the soaking liquid through the pot. The increased temperature accelerates the diffusion rate of water molecules, causing the collagen in the fish maw to absorb water and swell, thus shortening the soaking time.

[0041] like Figure 1As shown, in some embodiments, the pot body 100 is provided with a water inlet pipe 170 and a drain pipe 180. The water inlet pipe 170 is located on the upper side of the pot body 100, and the drain pipe 180 is located at the bottom of the pot body 100. The drain pipe and the water inlet pipe can achieve mid-process water replacement to remove fishy smells and impurities. During the soaking process of fish maw, impurities such as grease, blood, and mucus (containing histamine, trimethylamine, and other fishy-smelling substances) are released. The old liquid is discharged through the drain pipe, and new water is injected through the water inlet pipe, which can improve cleanliness. In some specific embodiments, the water inlet pipe and the drain pipe can be connected to a circulation pump to form a "filtration-recirculation" system: the soaking liquid discharged from the drain pipe is filtered through a filter screen (retaining grease and debris) and then reinjected into the pot body through the water inlet pipe, realizing liquid recycling, reducing water waste, and at the same time, the circulation flow enhances the flushing effect and helps remove the adhering substances on the surface of the fish maw.

[0042] In some specific embodiments, a liquid level sensor is installed inside the pot. The sensor monitors the water level in real time. When the injected water volume reaches a set value (e.g., four times the weight of the fish maw), the valve in the water inlet pipe is automatically closed, avoiding errors caused by manual estimation. Simultaneously, the sensor dynamically monitors changes in the liquid level during soaking. As the fish maw absorbs water and expands during soaking, the liquid level drops. The sensor tracks these changes in real time, and if the liquid level falls below a threshold (e.g., a set minimum liquid level line), water is automatically added to maintain a surface covering the fish maw, preventing uneven soaking due to localized exposure.

[0043] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
