Description

Technical Field

[0001] This invention relates to fish processing equipment, specifically to a fish meat water retention device. Background Technology

[0002] During the processing, storage, and transportation of fish fillets, water-retaining agents are generally used to increase the moisture retention capacity and improve the stability of the water content. Current methods typically involve directly soaking the fish fillets in a container containing the water-retaining agent and letting them stand for a period of time. For the fish fillets to retain moisture sufficiently, the fish meat needs to be in close contact with the water-retaining agent to absorb water. Furthermore, in intensive fish processing plants, it is also necessary to consider the ease of placing and removing the fish fillets from the water-retaining agent containers, while maximizing the container's capacity. Solving these technical problems is a crucial issue that needs to be addressed.

[0003] For example, the patent "A Fish Fillet Water Retention Treatment Device" published in Chinese patent literature, with publication number CN210630560U and authorization announcement date of May 29, 2020, discloses a method to promote full contact between the fish meat and the water retention agent by setting a liftable stirring rod in a carrying tank to stir the fish fillets. However, the stirring process inevitably causes the fish fillets to break, resulting in waste. Therefore, stirring the fish fillets should be avoided in the water retention process.

[0004] For example, the patent "A Fish Fillet Water Retention Treatment Device" published in Chinese patent literature, with publication number CN215836872U and authorization announcement date of February 18, 2022, discloses a method of retaining water by spraying fish fillets by clamping them in a fixed component (i.e., a mesh clamp). This patent avoids using a stirring method to promote full contact between the fish meat and the water retention agent. However, whether it is clamping the fish fillets in the fixed component, taking them out of the fixed component, or using the atomized water retention method, the entire operation process is too inefficient and is not suitable for intensive production needs.

[0005] For example, the patent "A Tilapia Water Retention Device" published in Chinese patent literature, with publication number CN210642239U and authorization announcement date of June 2, 2020, discloses a device that places tilapia in a placement box and rotates it to retain water. This water retention device avoids directly stirring the fish fillets and allows the fish meat to fully contact the water retention agent. However, its spiral upward placement box design results in less space in the feed bucket, and the operation of putting in and taking out tilapia is particularly difficult. Therefore, it does not have practical value in intensive production.

[0006] None of the existing technologies described above offer an effective solution to the technical problems mentioned, nor do they provide any corresponding technical insights. Therefore, a new water-retention device for fish meat needs to be designed to address the aforementioned technical problems. Summary of the Invention

[0007] The purpose of this invention is to provide a fish fillet water retention device to solve the problems described in the background art. By designing a holding box and setting a three-dimensional grid inside the holding box that can create gaps between fish fillets, and equipping it with a mechanism that allows the holding box to easily feed and discharge materials, the fish fillets can fully contact the water retention agent without stirring, and the efficient feeding and discharging method is also suitable for intensive production.

[0008] The technical solution of this invention is implemented as follows:

[0009] A fish meat water retention device includes an outer box with an open top, a supporting component at the bottom of the outer box, and a detachable water-proof structure inside the outer box. The water-proof structure divides the interior of the outer box into an operating space and a sealed water-retaining space. A holding box with an open top is located in the water-retaining space. The holding box is rotatably mounted on the bottom wall of the outer box. A rotating shaft is located below the holding box. The rotating shaft passes through the bottom of the outer box and is driven by a reciprocating rotating mechanism located at the bottom of the outer box. At least two insert plates are detachably provided on the side wall of the holding box. Several long rods are inserted into one side of the insert plate. The insert plate is slidably inserted into the side wall of one side of the holding box through the long rods. The long rods pass through the interior of the holding box and slide into the side wall of the other side of the holding box. A discharge door is also provided at the bottom of the side wall of the holding box. A drainage device for draining water from the outer box and a discharge device for discharging material from the outer box are also provided in the water-retaining space.

[0010] A further technical solution is that the side wall of the container is provided with several insertion holes for inserting long rods. The diameter of the insertion holes is larger than the outer diameter of the long rod. The insertion holes are arranged to form a grid pattern with horizontal and vertical rows intersecting. Adjacent vertical rows of insertion holes are staggered horizontally, and adjacent horizontal columns of insertion holes are staggered vertically. The long rod is horizontally inserted into the container through the insertion holes on one side wall and then horizontally exits through the insertion holes on the opposite side wall of the container.

[0011] A further technical solution is that the insertion plate is provided with at least one handle on the side facing away from the long rod, and a support rod is provided on the outer inner side wall of the operating space. The insertion plate is also provided with a support block that cooperates with the support rod or has a support hole that cooperates with the support rod. The insertion plate is placed on the support rod through the support block or the support hole.

[0012] A further technical solution is that the discharge device includes a discharge hopper and a discharge pipe. The discharge hopper is fixedly installed on the bottom wall of the outer box and is located directly below the discharge gate. The discharge pipe passes through the bottom wall of the outer box, and the upper end of the discharge pipe is connected to the bottom outlet of the discharge hopper. The lower end of the discharge pipe is also provided with a discharge valve.

[0013] A further technical solution is that several grooves are formed on the outer surface of the long rod, and the edges of the grooves are rounded and smoothed.

[0014] A further technical solution is that the reciprocating rotation mechanism includes a support frame fixed to the bottom of the outer casing. The support frame includes a suspension rod fixed to the bottom of the outer casing and a support plate fixed to the bottom of the suspension rod. The reciprocating rotation mechanism also includes a first pulley and a second pulley fixed to a rotating shaft below the outer casing. A first support shaft, a second support shaft, and a motor are also fixedly mounted on the support plate. A first gear, a second gear, a third pulley, and a fourth pulley are rotatably mounted on the first support shaft. The third pulley is fixed to the first gear, and the fourth pulley is fixed to the second gear. The first pulley and the third pulley are driven by each other. A fifth pulley and a third gear are rotatably mounted on the second support shaft. The third gear is fixed to the fifth pulley and is driven by the motor. The third gear is an incomplete gear with only some teeth on a gear plate. The first gear and the second gear alternately mesh with the third gear.

[0015] A further technical solution is that the drainage device is a drain pipe installed at the bottom of the outer casing, with a drain valve on the drain pipe. The upper end of the drain pipe is connected to the water-retaining space, and the lower end is connected to the outside of the outer casing.

[0016] A further technical solution is that the water-proof structure includes a water-proof groove that is sealed and fixed on the inner wall of the outer casing and a detachable water-proof plate that is sealed and inserted in the water-proof groove.

[0017] A further technical solution is that the container is provided with a partition wall inside, and the partition wall has an insertion hole that matches the side wall of the container. A certain distance is left between the partition wall and the side wall of the container with the insertion hole.

[0018] A further technical solution is that the insertion plate is also provided with a fixing structure, which includes a limiting block protruding upward from the upper end of the insertion plate and a limiting groove opened at the lower end of the insertion plate. The limiting block is also provided with a through hole. When the lower insertion plate is inserted into the container, when the upper insertion plate is inserted, the limiting block on the lower insertion plate fits into the limiting groove of the upper insertion plate. The upper insertion plate is screwed to the side wall of the container through the through hole.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. By setting up a holding box with an internal three-dimensional grid and discharge port, and staggering the long rods, the three-dimensional grid divides the interior of the holding box into multiple interconnected storage spaces. When fish fillets are put into the holding box through the opening at the top, they slide into the box along the gaps in the grid formed by the long rods. Due to the presence of the long rods, the fish fillets cannot be tightly stacked together, leaving gaps between them. These gaps are filled with a water-retaining agent, allowing more surface area of ​​the fish fillets to contact the water-retaining agent, thus improving the water retention effect, water retention rate, and integrity of the fish fillets without stirring. At the same time, this invention makes full use of the container's loading capacity, allowing for a larger loading of fish fillets compared to existing technologies. When used in intensive fish processing plants, the bottom discharge door makes the fish fillet removal rate more efficient than existing technologies.

[0021] 2. By setting up a reciprocating rotation mechanism to reciprocate the holding box, the holding box not only allows the fish fillets to fall into the gaps of the long rod during the rotation, but also simultaneously applies centrifugal force to the fish fillets, throwing them to the sides of the holding box, so that the fish fillets can fall evenly into the holding box, making the rate at which the fish fillets are put into the holding box more efficient than existing technologies.

[0022] 3. By setting up the insertion plate and support rod, the insertion plate realizes the function of pulling out and inserting a large number of long rods at one time. The support rod supports the insertion plate when it is pulled out, so that the long rod is always in the insertion hole of the holding box. This avoids pulling the insertion plate out of the insertion hole completely, and avoids the time-consuming and laborious process of lifting the insertion plate again to align it with the insertion hole when it is pulled out and then inserted.

[0023] 4. By setting up a partition wall, when the long rod is removed from the container, it is pulled out to the space between the partition wall and the side wall. This prevents the fish fillets from getting stuck on the long rod during feeding and avoids the inconvenience caused by the long rod being completely removed from the insertion hole.

[0024] 5. By creating several grooves on the outer surface of the long rod, with rounded edges and smooth polishing, these grooves increase the gap between the fish fillet and the long rod, allowing the water-retaining agent to penetrate and increasing the contact area between the fish fillet and the water-retaining agent. The rounded edges and smooth polishing prevent the grooves from scratching or pinching the fish meat when the long rod is pulled out, maintaining the integrity of the fish fillet.

[0025] 6. By setting up a water-proof structure, a water-retaining space is created. When retaining water, only the water-retaining space needs to be filled, which speeds up the filling time and saves water-retaining agent. Attached Figure Description

[0040] To better understand the technical content of this invention, specific embodiments are provided below, and the invention will be further described in conjunction with the accompanying drawings.

[0041] See Figures 1 to 13 A fish meat water retention device includes an outer box 1 with an open top. A support component 14 is provided below the outer box 1 to lift the bottom of the outer box 1 off the ground. The outer box 1 has a detachable water-proof structure inside, which divides the interior of the outer box 1 into an operating space 11 and a sealed water-retention space 6. A holding box 3 is provided in the water-retention space 6. The holding box 3 is a container with an open top and is rotatably mounted on the bottom wall of the outer box 1. A rotating shaft 19 is provided below the holding box 3 and passes through the bottom of the outer box 1. Driven by a reciprocating rotating mechanism fixed to the bottom of the outer box 1, the side wall of the holding box 3 is also provided with several insertion plates 7. Several long rods 2 are inserted on one side of the insertion plate 7. The insertion plate 7 is slidably inserted into the side wall of the holding box 3 through the long rods 2. The long rods 2 are inside the holding box 3 and slide through the holding box 3 into the side wall of the other side of the holding box 3. The bottom of the side wall of the holding box 3 is also provided with a discharge door 5. The water-retaining space 6 is also provided with a drainage device for draining the outer box 1 and a discharge device for discharging the material from the outer box 1.

[0042] Specifically, the outer box 1 is a rectangular box made of stainless steel, and the supporting component 14 is an angle steel welded to the bottom of the outer box 1.

[0043] Specifically, the container 3 is a rectangular stainless steel box. Multiple insertion holes 47 are provided on the side wall of the container 3. The diameter of the insertion hole 47 is larger than the outer diameter of the long rod 2. The long rod 2 is horizontally inserted into the container 3 through the insertion hole 47 on one side wall of the container 3 and horizontally exits through the insertion hole 47 on the opposite side wall of the container 3. The water-retaining agent in the water-retaining space 6 can enter and exit the container 3 through the gap between the insertion hole 47 and the long rod 2.

[0044] Multiple horizontally arranged long rods 2 form a three-dimensional grid inside the holding box 3, dividing the interior of the holding box 3 into multiple interconnected storage spaces. When fish fillets are put into the holding box 3 through the opening at the top, the fish fillets slide into the holding box 3 along the gaps formed by the long rods 2. Due to the presence of the long rods 2, the fish fillets cannot be tightly stacked together, leaving gaps between the fish fillets. These gaps are filled with a water-retaining agent, allowing more of the surface of the fish fillets to come into contact with the water-retaining agent.

[0045] Specifically, in order to make it easier to form gaps between fish fillets, the holes 47 on the side wall of the holding box 3 are staggered. Several holes are arranged to form a grid pattern with horizontal and vertical rows intersecting each other. The holes 47 in adjacent upper and lower rows are staggered horizontally, and the holes 47 in adjacent left and right columns are staggered vertically.

[0046] It should be noted that when the insertion holes 47 are misaligned, the fish fillets may have difficulty falling directly into the bottom of the holding box 3. In this case, it is necessary to apply external force to the holding box 3 appropriately, such as by vibrating, shaking, or rotating it, to make it easier for the fish fillets to fall into the bottom of the holding box 3. Vibrating and shaking the holding box 3 may cause the fish fillets to concentrate in one point or line, i.e., too much accumulates in the middle and less accumulates around the edges. Therefore, rotating the holding box 3 is chosen to handle this. During the rotation, centrifugal force is applied to the fish fillets, throwing them to the edges of the holding box 3, so that the fish fillets can fall evenly into the interior of the holding box 3.

[0047] Specifically, a bearing 18 is fixedly installed on the bottom wall of the outer casing 1, and a rotating shaft 19 below the holding box 3 passes through the bearing 18 and the bottom of the outer casing 1. The reciprocating rotation mechanism includes a support frame welded to the bottom of the outer casing 1. The support frame includes a hanging rod 26 and a support plate 27. A first pulley 20 and a second pulley 21 are fixedly installed on the rotating shaft 19 below the outer casing 1. A first support shaft 30 and a second support shaft 32 are welded to the support plate 27. A first gear 22, a second gear 29, a third pulley 23, and a fourth pulley 28 are rotatably mounted on the first support shaft 30. The first gear 22 and the third pulley 23 are fixedly installed together, and the second gear 29 and the fourth pulley 28 are fixedly installed together. The first pulley 20 and the third pulley 23 are driven by a belt, and the second pulley 21 and the fourth pulley 28 are driven by a belt. A fifth pulley 25 and a third gear 24 are rotatably mounted on the second support shaft 32. The fifth pulley 25 and the third gear 24 are fixedly installed together. The third gear 24 is an incomplete gear. The first gear 22 and the second gear 29 alternately mesh with the third gear 24. A motor 33 is also mounted on the support plate 27. A sixth pulley 31 is provided on the output shaft of the motor 33. The fifth pulley 25 and the sixth pulley 31 are driven by a belt.

[0048] See Figure 3 The third gear 24 has only some teeth 17. When the third gear 24 rotates in a fixed direction, the third gear 24 meshes alternately with the first gear 22 and the second gear 29, causing the rotating shaft 19 to reciprocate. The rotating shaft 19 drives the container 3 to reciprocate.

[0049] It should be noted that after the holding box 3 is full of fish fillets, water-retaining agent is injected into the water-retaining space 6. The water-retaining agent will fill the entire water-retaining space 6. After the water-retaining time is up, the water-retaining agent in the water-retaining space 6 must be emptied before the fish fillets can be taken out.

[0050] Specifically, the drainage device is a drain pipe 15 located at the bottom of the outer casing 1, with a drain valve 16 on the drain pipe 15, and the drain pipe 15 is connected to the water-retaining space 6. Opening the drain valve 16 will drain the water-retaining agent in the water-retaining space 6 through the drain pipe 15.

[0051] Specifically, a discharge port 44 is provided at the bottom of the side wall of the container 3. A slide rail 4 is provided on the side wall of the container 3 next to the discharge port 44. The discharge door 5 is a long plate that is slidably inserted into the slide rail 4. The opening and closing of the discharge port 44 is controlled by pushing and pulling the long plate to slide in the slide rail 4. A damping strip is provided inside the slide rail 4 so that the discharge door 5 is damped when sliding in the slide rail 4, so as to prevent the discharge door 5 from being thrown out when the container 3 is swinging.

[0052] Specifically, the discharge device includes a discharge hopper 35 and a discharge pipe 36. The discharge hopper 35 is fixed to the bottom wall of the outer casing 1, and is located directly below the discharge port 44. The discharge pipe 36 passes through the bottom wall of the outer casing 1, with its upper end connected to the bottom outlet of the discharge hopper 35, and a discharge valve at its lower end. When the discharge door 5 is opened, the discharge port 44 is exposed, and the fish fillets in the container 3 are discharged from the discharge port 44 into the discharge hopper 35, and then discharged from the outer casing 1 via the discharge pipe 36.

[0053] It should be noted that when the long rod 2 is inserted inside the holding box 3, the fish fillets cannot be discharged on their own. Therefore, the long rod 2 needs to be pulled out of the holding box 3. After the grid formed by the long rod 2 is removed, the fish fillets will naturally fall to the bottom of the holding box 3 and then be discharged through the discharge port 44. Pulling out the long rod 2 one by one would be time-consuming. Therefore, these long rods 2 need to be fixed to the rod plate 7. By pulling one rod plate 7, the function of pulling out multiple long rods 2 can be achieved. However, if only one rod plate 7 is used, the weight of the rod plate 7 will be too heavy and difficult to operate.

[0054] Specifically, the insertion plate 7 is a rectangular plate, and its width is exactly equal to the width of the holding box 3. In this embodiment, there are three insertion plates 7, which are inserted into the holding box 3 from top to bottom via long rods 2. Two handles 8 are provided on the side of the insertion plate 7 facing away from the long rods 2, and the handles 8 are respectively located at both ends in the length direction. When it is necessary to pull out the long rods 2, two workers can each grab one of the handles 8 to pull the long rods 2 out of the holding box 3.

[0055] Specifically, to prevent the insertion plate 7 and the long rod 2 from being thrown out when the container 3 rotates, the insertion plate 7 is also provided with a fixing structure. The fixing structure includes a limiting block 43 protruding upward from the upper end of the insertion plate 7 and a limiting groove 46 opened at the lower end of the insertion plate 7. The fixing structure also includes a threaded hole opened on the side wall of the container 3. The limiting block 43 is also provided with a through hole 45. When the lower insertion plate 7 is inserted into the container 3, when the upper insertion plate 7 is inserted, the limiting block 43 on the lower insertion plate 7 fits into the limiting groove 46 of the upper insertion plate 7. The uppermost insertion plate 7 is fixed in the threaded hole on the side wall of the container 3 by bolts passing through the through hole 45.

[0056] It should be noted that if the plug plate 7 is completely pulled out of the socket 47, it will be necessary to lift it up and align it with the socket 47 again when inserting it, which is time-consuming and laborious. Therefore, when pulling out the plug plate 7, a part of the long plate should be left in the socket 47, and the plug plate 7 needs a support to support the column to prevent it from falling.

[0057] Specifically, a support rod 12 is inserted into the side wall of the operating space 11 of the outer casing 1, and corresponding support blocks 42 are provided on both sides of the insertion plate 7. When the insertion plate 7 is placed on the support rod 12 through the support blocks 42, the long rod 2 is basically in a horizontal state, and the upper and lower adjacent insertion plates 7 do not interfere with each other. Support holes can also be opened on the insertion plate 7, and the support rod 12 is inserted into the support hole to form support.

[0058] Specifically, to prevent fish fillets from getting caught on the long rod 2 during discharge, the long rod 2 needs to be completely pulled out of the insertion hole 47. However, completely pulling the long rod 2 out of the insertion hole 47 makes reinstallation inconvenient. To solve this technical problem, a partition wall 34 is provided inside the holding box 3, and the partition wall 34 has insertion holes 47 that match the side wall. When it is necessary to pull out the long rod 2, it is pulled out until the end of the long rod 2 is in the space between the partition wall 34 and the side wall.

[0059] Specifically, in order to facilitate the discharge of fish fillets, the bottom of the holding box 3 is sloped, and the slope is inclined towards the discharge port 44.

[0060] Specifically, to increase the contact area between the fish fillet and the water-retaining agent, several grooves 48 are formed on the outer surface of the long rod 2. The edges of the grooves 48 are rounded and smoothly polished. These grooves 48 increase the gap between the fish fillet and the long rod 2, allowing the water-retaining agent to enter and increasing the contact area between the fish fillet and the water-retaining agent. Furthermore, the rounded edges and smooth polishing of the grooves 48 prevent scratching or pinching the fish meat when the long rod 2 is pulled out, maintaining the integrity of the fish fillet.

[0061] Specifically, in order to facilitate personnel access to the operating space 11, a door 13 for entering and exiting the operating space 11 is provided on the upper side wall of the outer casing 1.

[0062] It should be noted that, because it is necessary to ensure that the insertion plate 7 and the long rod 2 do not completely detach from the insertion hole 47 when pulled out, this device needs to be equipped with an operating space 11 to place the insertion plate 7. If the entire outer box 1 is filled during the water retention operation, the filling time will be too slow and the water retention agent will be wasted. Therefore, a water-proof structure is needed to separate the water retention space 6. During water retention, only the water retention space 6 needs to be filled, which speeds up the filling time and saves water retention agent.

[0063] Specifically, the water-proof structure includes a water-proof groove 9 welded to the inner wall of the outer casing 1 and a water-proof plate 10 inserted in the water-proof groove 9. The water-proof groove 9 includes a 'U'-shaped plate frame welded to the inner wall of the outer casing 1 and a baffle 39 welded to the inner bottom wall of the outer casing 1. The plate frame includes two side plates 37 and a bottom plate 38 set at the bottom of the two side plates 37. A V-shaped sealing strip 41 with an upward opening is provided between the bottom plate 38 and the baffle 39. A sealing strip 40 is glued to the side of the side plate 37 facing the operating space 11. The water-proof plate 10 is inserted in the V-shaped sealing strip 41 between the bottom plate 38 and the baffle 39. The two sides of the water-proof plate 10 are pressed against the sealing strip 40 of the side plate 37. The side plate 37 has several screw holes, and the water-blocking plate 10 has several fastening holes on both sides that mate with the screw holes. The water-blocking plate 10 is screwed into the screw holes through the fastening holes by bolts, pressing the water-blocking plate 10 into the water-blocking groove 9 to achieve the water-blocking function. After the water-retaining agent in the water-retaining space 6 is emptied, the bolts on the water-blocking plate 10 are removed using an electric gun, and the water-blocking plate 10 can be removed and placed against the inner wall of the outer casing 1 of the operating space 11.

[0064] Working principle of this invention:

[0065] When using this equipment, the operator first enters the outer casing 1 and inserts all the insert plates 7 into the holding box 3. The long rods 2 form a staggered three-dimensional grid inside the holding box 3. The fish fillets are transported to the top of the holding box 3 via a conveyor belt and fall into the holding box 3. The motor 33 is then turned on, and the motor 33 drives the holding box 3 to rotate back and forth through the gear system and transmission system. After the fish fillets gradually fill the entire holding box, the motor 33 is stopped. Then, the operator installs the water-separating plate 10 and injects water-retaining agent into the water-retaining space 6. After retaining water for a period of time, the drain valve 16 is opened to drain the water-retaining agent. The operator then enters the operating space 11, removes the water-separating plate 10, removes the bolts of the top insert plate 7, pulls the insert plates 7 out from top to bottom, and places them on the support rod 12. Then, the discharge gate 5 is pulled out from the slide rail 4, exposing the discharge port 44. The fish fillets fall from the discharge port 44 into the discharge hopper 35 and are discharged from the discharge pipe 36.

[0066] When it is time to retain the next batch of fish fillets, first insert the discharge gate 5 along the slide rail 4 to block the discharge port 44, then insert the insertion plate 7 and the long rod 2 into the holding box 3 from bottom to top, and then repeat the above operation.

[0067] When retaining water in fish fillets, this equipment makes full use of the three-dimensional grid formed by the long rods 2 and the grooves 48 on the outer wall of the long rods 2. This ensures that the fish fillets are not simply stacked inside the holding box 3. Instead, the fish fillets can create many gaps during stacking due to the blocking effect of the long rods 2 and the air-blocking effect of the grooves 48 on the long rods 2. These gaps increase the contact area between the fish fillets and the water-retaining agent, making the water absorption area of ​​the fish fillets more comprehensive, the water absorption volume more, and the water absorption efficiency higher. At the same time, it avoids promoting contact between the fish meat and the water-retaining agent by stirring the fish fillets, avoiding the breakage of the fish fillets caused by stirring, and ensuring the integrity of the fish fillets.

[0068] Meanwhile, this equipment makes full use of the container's capacity when holding fish fillets, holding more fish fillets than existing technologies. When used in intensive fish processing plants, the rate of putting in and taking out fish fillets is also more efficient than existing technologies.

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
