Description

Technical Field

[0001] This invention belongs to the field of freshwater shrimp processing technology, specifically a separation device and method for aquatic products. Background Technology

[0002] Freshwater shrimp, also known as river shrimp or freshwater prawns, are a common high-quality aquatic product in freshwater aquaculture. They are prized for their tender meat, rich in nutrients, and have high nutritional and economic value. The main reasons for shelling them in aquatic product processing include: firstly, the shells are tough and difficult to digest, removing them allows consumers to enjoy ready-to-eat or cooked shrimp; secondly, shrimp heads and shells easily accumulate microorganisms and enzymes, and storing them with the shells on can lead to blackening and spoilage, while shelling effectively extends shelf life and improves hygiene and safety; and thirdly, after shelling, the shrimp shells can be used separately to extract high-value-added components such as astaxanthin and chitin, achieving comprehensive utilization of by-products.

[0003] Existing shrimp peeling technologies mostly employ rigid extrusion or kneading processes, which have significant drawbacks: First, rigid mechanical contact easily leads to shrimp meat breakage; second, the single mechanical structure has poor adaptability to shrimp size, easily resulting in incomplete peeling or excessive extrusion when dealing with shrimp of varying sizes; third, the equipment has many dead corners, making it difficult to clean shrimp meat mucus and shell fragments, which easily breed bacteria and pose a high hygiene risk; fourth, the separation of shell and meat is incomplete, requiring a large amount of manual picking of broken shrimp shells after separation, resulting in low processing efficiency, high labor costs, and difficulty in meeting the needs of large-scale, high-cleanliness production.

[0015] A method for separating aquatic products, applicable to the aforementioned aquatic product separation device, includes the following steps: S1: Use a rubber pressure plate to hold down the headless shrimp, so that its back faces the side of the impact pipe and its tail faces away from the feed pipe. Then use a cutting knife to cut open the back of the shrimp. S2: Move the impact tube toward the shrimp's back and use the high-pressure fine water jet from the impact tube to impact the opening on the shrimp's back, widening the opening and separating the shrimp meat from the shell.

[0016] The beneficial effects of this invention are as follows: 1. This invention uses a rubber clamp to flexibly hold the shrimp, avoiding damage caused by rigid compression. An adjustable telescopic frame drives a cutting blade to adapt to the backs of shrimp of different sizes. High-pressure, fine water is precisely injected into the gap between the shell and meat through an impact tube. The flexible impact of the water flow achieves non-contact initial shell-meat separation, reducing physical damage and accommodating various shrimp sizes. Subsequently, a suction tube with adsorption holes adsorbs the shrimp meat under negative pressure and smoothly extracts it, significantly improving the integrity of the shell removal process. The device features a smooth surface and modular design, reducing cleaning dead zones and effectively inhibiting bacterial growth. Compared to traditional processes, this invention significantly reduces manual sorting while ensuring shrimp meat integrity, improving processing efficiency and food safety, making it suitable for large-scale, high-cleanliness aquatic product processing scenarios.

[0017] 2. This invention improves the post-processing cleaning process by incorporating a sludge collection trough, a pull-out sludge collection box, and a wastewater tank. After the shrimp meat is separated, the electric push rod and its associated mechanism are moved horizontally, using a rubber pressure plate to sweep intact shrimp shells and attached debris into the sludge collection trough. Subsequently, the rubber pressure plate is controlled to reset and press down, repeatedly scraping the work surface to thoroughly remove residual water stains and tiny shell fragments, solving the problem of slime accumulation and bacterial growth in equipment dead corners. Shrimp shells and wastewater fall into the sludge collection box through the sludge collection trough, while the liquid drains into the wastewater tank through a drain hole. Fine debris is trapped by a filter plate, achieving efficient solid-liquid separation and significantly reducing the difficulty of subsequent wastewater treatment. Both the sludge collection box and the wastewater tank feature a pull-out design, coupled with a removable filter plate, facilitating quick cleaning and maintenance, effectively ensuring a continuously hygienic processing environment, and meeting the needs of large-scale, high-cleanliness production.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] Example 1: As Figures 1 to 5 and Figure 7 and Figure 8 As shown in the figure, an aquatic product separation device according to an embodiment of the present invention includes a processing table 1. A connecting rod 2 is fixedly connected to the top of the processing table 1. A connecting plate 3 is fixedly connected to the top of the connecting rod 2. A plurality of electric push rods 4 and a drive controller 1 are fixedly connected to the bottom of the connecting plate 3. The same rubber pressure plate 5 is fixedly connected to the telescopic ends of the plurality of electric push rods 4. A connecting block 6 is fixedly connected to the top of the processing table 1. An electric push rod 7 and a drive controller 2 are fixedly connected to the side of the connecting block 6. A circular block 8 is fixedly connected to the telescopic end of the electric push rod 7. A socket plate 9 is fixedly connected to the outside of the circular block 8. A micro air pump 1 and a start / stop controller 1 are installed inside the circular block 8. A telescopic frame 10 is movably inserted into the side end of the socket plate 9. A cutting blade 11 is fixedly connected to the side of the telescopic frame 10 away from the socket plate 9. The top of the processing table 1 is fixedly connected to a connecting block 2 12. The side of the connecting block 2 12 is fixedly connected to an electric push rod 3 13 and a drive controller 3. The telescopic end of the electric push rod 3 13 is fixedly connected to a mounting plate 14. The mounting plate 14 is equipped with a micro air pump 2 and a start / stop controller 2. The side of the mounting plate 14 away from the electric push rod 3 13 is fixedly connected to a material picking tube 15. The material picking tube 15 is provided with equally spaced adsorption holes. The processing table 1 has a horizontal plate 16 on its top and a movable plate 17 on its side. An electric push rod 18 and a drive controller 18 are fixedly connected between the movable plate 17 and the horizontal plate 16. Several impact pipes 19 are fixedly connected to the side of the movable plate 17 away from the electric push rod 18. A pair of symmetrically distributed water injection pipes are fixedly connected to the top of the movable plate 17. An electric push rod 20 and a drive controller 20 are fixedly connected between the processing table 1 and the horizontal plate 16.

[0023] In existing technologies, most shrimp peeling techniques employ rigid extrusion or kneading processes, which have significant drawbacks: First, rigid mechanical contact easily leads to shrimp meat breakage; second, the single mechanical structure has poor adaptability to shrimp size, and is prone to incomplete peeling or excessive extrusion when dealing with shrimp of varying sizes; third, the equipment has many dead corners, making it difficult to clean shrimp meat mucus and shell fragments, which easily breed bacteria and pose a high hygiene risk; fourth, the separation of shell and meat is incomplete, requiring a large amount of manual picking of broken shrimp shells after separation, resulting in low processing efficiency, high labor costs, and difficulty in meeting the needs of large-scale, high-cleanliness production. The present invention is used in the following steps: Step 1: Manually place the headless shrimp under the rubber pressure plate 5 on the processing table 1, with the shrimp back facing the impact tube 19, the shrimp tail close to the connecting rod 2, and the end connected to the shrimp head facing the feeding tube 15. Start the electric push rod 4, so that its telescopic end pushes the rubber pressure plate 5 down, and uses the rubber pressure plate 5 to apply pressure to the top of the shrimp body, clamping and fixing it on the processing table 1; Step 2: Start the micro air pump 1 to inject air into the socket plate 9. Under the action of the gas thrust, the telescopic frame 10 moves together with the cutting blade 11 toward the shrimp back until the cutting blade 11 comes into contact with the shrimp back and applies a certain pressure to the shrimp back. Use the cutting blade 11 to cut an opening in the shrimp back. Start the electric push rod 7, so that its telescopic end pushes the cutting blade 11 to move together, so that the cutting blade 11 can cut the back of different shrimp bodies; Step 2: Activate electric push rod 418 to move impact tube 19 toward the shrimp's back. At the same time, connect the water inlet of the high-pressure water injection device to the water injection pipe, so that a high-pressure fine water stream is sprayed out from the side end of impact tube 19. Use the high-pressure fine water stream to open the opening on the shrimp's back and allow water to enter the shrimp shell. Use the impact of the high-pressure fine water stream to separate the shrimp meat from the shell. At the same time, activate electric push rod 520 to fine-tune the vertical position of impact tube 19 to adjust the position of impact on the shrimp meat. When using high-pressure fine water flow to separate shrimp meat from shell, the rubber pressure plate 5 is deformable, so it will deform to a certain extent when it is squeezed and impacted by the water flow, which makes it easier for the water flow to enter the shell and come into contact with the shrimp meat. Step 3: After the shrimp meat separates from the inner wall of the shell, start the electric push rod 13 to push the feeding tube 15 towards the shrimp body until the feeding tube 15 comes into contact with the shrimp meat. Then start the micro air pump 2 to apply negative pressure to the shrimp meat through the suction hole. Finally, pull back the feeding tube 15 to pull the shrimp meat out of the shell, thus separating the shrimp meat from the shell.

[0024] In summary, this invention uses a rubber clamping plate 5 to flexibly hold the shrimp body, avoiding damage caused by rigid compression. An adjustable telescopic frame 10 drives a cutting blade 11 to adaptively fit the backs of shrimp of different sizes. High-pressure fine water is precisely injected into the gap between the shrimp shell and meat through an impact pipe 19, achieving non-contact initial separation of shell and meat through the flexible impact force of the water flow. This reduces physical damage and accommodates various shrimp sizes. Subsequently, the shrimp meat is adsorbed by negative pressure through a material extraction pipe 15 with suction holes and smoothly extracted, significantly improving the integrity of the shell removal process. The device features a smooth surface and modular design, reducing cleaning dead zones and effectively inhibiting bacterial growth. Compared to traditional processes, this invention significantly reduces manual sorting intensity while ensuring shrimp meat integrity, improving processing efficiency and food safety, making it suitable for large-scale, high-cleanliness aquatic product processing scenarios.

[0025] like Figure 1 and Figure 6 As shown, the material picking tube 15 is equipped with several position sensors and sensor controllers, and a collection box 21 is movably inserted into the top of the processing table 1, with the top of the collection box 21 flush with the top of the processing table 1. The feeding tube 15 applies negative pressure to the shrimp meat and pulls back the feeding tube 15, causing the shrimp meat to move together. When the position sensor detects that the shrimp meat has moved directly above the collection box 21, the sensor controller at the corresponding position will remove the negative pressure adsorption effect of the adsorption hole on the shrimp meat, so that the shrimp meat falls into the collection box 21, making it easier for personnel to collect the peeled shrimp meat.

[0026] like Figure 1 As shown, the inner bottom wall of the collection box 21 is provided with several water outlet holes 22, the inside of the processing table 1 is provided with a cavity, the side of the processing table 1 is fixedly connected with a drain pipe 23, the side end of the drain pipe 23 communicates with the cavity, and the top of the drain pipe 23 is provided with a drain valve. During the process of collecting shrimp meat using the collection box 21, the water in the shrimp meat will gradually separate from the shrimp meat and enter the drain pipe 23 through the water outlet 22. Then the water can be discharged through the drain pipe 23. This can separate the water in the shrimp meat, reduce the overall weight of the collection box 21, and simplify the subsequent shrimp meat processing procedures.

[0027] like Figure 1As shown, the bottoms of the cutting blade 11, the material taking tube 15, and the impact tube 19 all abut against the top of the processing table 1. In the initial state, there is a gap between the bottom of the rubber pressure plate 5 and the top of the processing table 1.

[0028] Example 2: This embodiment is based on the first embodiment, but the connection between the connecting rod 2 and the processing table 1 is changed from a fixed connection to an abutment connection. The rest remains the same as the first embodiment, as follows: like Figure 5 and Figure 9 As shown, a fixing block 24 is fixedly connected to the top of the processing table 1. An electric push rod 25 and a drive sensor 6 are fixedly connected to the side of the fixing block 24 near the connecting rod 2. A sludge collection trough 26 is provided on the top of the processing table 1. A pull-out groove 1 and a pull-out groove 2 are provided on the side of the processing table 1 from top to bottom. A sludge collection box 27 is movably inserted inside the pull-out groove 1. A sewage tank 28 is movably inserted inside the pull-out groove 2. Both the sewage tank 28 and the bottom of the processing table 1 are equipped with casters to facilitate the movement of the sewage tank 28 and the processing table 1. A filter plate 31 is movably inserted inside the sewage tank 28. The telescopic end of the electric push rod 25 is fixedly connected to the connecting rod 2. A drain hole is provided on the inner bottom wall of the pull-out groove 1, a sealing frame is fixedly connected to the outside of the sludge collection box 27, and a water leakage hole communicating with the drain hole is provided on the inner bottom wall of the sludge collection box 27. The sewage tank 28 has a pair of inner sidewalls with insertion slots 34, and the filter plate 31 has a pair of sidewalls with insertion blocks 35 that are adapted to the insertion slots 34.

[0029] The present invention is used in the following steps: Step 1: After removing the shrimp meat from the shrimp shell, the electric push rod 25 needs to be activated so that its telescopic end can push the connecting rod 2 and all its mechanisms together toward the sludge collection tank 26, thereby using the rubber pressure plate 5 to push the shrimp shell into the sludge collection tank 26. Then move the rubber pressure plate 5 up and pull it back to reset. After resetting, start the electric push rod 4 to move the rubber pressure plate 5 down until the bottom of the rubber pressure plate 5 abuts against the top of the processing table 1. Then repeat the above steps to make the electric push rod 25 push the rubber pressure plate 5 to move on the processing table 1, so as to use the rubber pressure plate 5 to push the shrimp shell fragments and water stains attached to the processing table 1 from the processing table 1 into the sludge collection tank 26. Step 2: Shrimp shell fragments and wastewater will fall into the waste collection tank 27 through the waste collection trough 26. The waste collection tank 27 is used to collect the shrimp shells. The water in the shrimp shells will be removed from the waste collection tank 27 through the drain hole and fall into the wastewater tank 28. The filter plate 31 in the sewage tank 28 is used to filter the shrimp shell debris mixed in the water, thereby improving the cleanliness of the sewage and reducing the number of subsequent sewage treatment steps. Finally, the sludge collection tank 27 is periodically pulled out from the first pull-out channel, and the sewage tank 28 is pulled out from the second pull-out channel. The shrimp shells in the sludge collection tank 27 and the sewage in the sewage tank 28 are then removed.

[0030] In summary, this invention improves the post-processing cleaning process by incorporating a sludge collection trough 26, a pull-out sludge collection box 27, and a wastewater tank 28. After the shrimp meat is separated, the electric push rod 25 drives the connecting rod 2 and related mechanisms to move horizontally. The rubber pressure plate 5 sweeps the intact shrimp shells and attached debris into the sludge collection trough 26. Subsequently, the rubber pressure plate 5 is controlled to reset and press down, repeatedly scraping the work surface to thoroughly remove residual water stains and tiny shell fragments, solving the problem of easy accumulation of slime and bacterial growth in equipment dead corners. Shrimp shells and wastewater fall into the sludge collection box 27 through the sludge collection trough 26, while the liquid drains into the wastewater tank 28 through the drain hole. Fine debris is trapped by the filter plate 31, achieving efficient solid-liquid separation and significantly reducing the difficulty of subsequent wastewater treatment. Both the sludge collection box 27 and the wastewater tank 28 adopt a pull-out design, combined with the detachable filter plate 31, facilitating quick cleaning and maintenance, effectively ensuring the continuous hygiene of the processing environment, and meeting the needs of large-scale high-cleanliness production.

[0031] like Figure 5 As shown, the sewage tank 28 is equipped with a water level sensor and an alarm controller. An alarm 29 is fixedly connected to the outside of the sewage tank 28. The sludge collection tank 27 is equipped with a material detector and an alarm controller. An alarm 30 is fixedly connected to the outside of the sludge collection tank 27. During the collection of sewage and shrimp shells, once the amount of sewage and shrimp shells reaches the set value, alarm 1 29 and alarm 2 30 will emit audible and visual signals to remind personnel to handle the sewage in sewage tank 28 and the shrimp shells in sewage collection tank 27.

[0032] like Figure 5 As shown, a pair of inner sidewalls of the pull-out groove 2 are provided with sliding grooves 32, and a pair of sidewalls of the sewage tank 28 are fixedly connected with sliding plates 33 that are adapted to the sliding grooves 32. After the sewage tank 28 is inserted into the pull-out groove 2, the sliding plate 33 will be inserted into the sliding groove 32. The sliding plate 33 can improve the stability of the sewage tank 28 in the pull-out groove 2.

[0033] like Figure 5 As shown, a pair of inner sidewalls of the pull-out groove are coated with a magnetic coating 36, and a pair of sidewalls of the sludge collection box 27 are coated with a magnetic coating 37 that is magnetically connected to the magnetic coating 36. After the magnetic coating 37 and the magnetic coating 36 are magnetically connected together, the stability of the sludge collection box 27 in the pull-out groove is improved.

[0034] like Figure 5 As shown, a motor and a motor controller are fixedly connected to the inner bottom wall of the sludge collection box 27. A round rod 38 is fixedly connected to the output end of the motor, and several symmetrically distributed stirring rods 39 are fixedly connected to the outer side of the round rod 38. During the process of collecting shrimp shells using the sludge collection box 27, the motor can be started, so that its output end drives the round rod 38 and the stirring rod 39 to rotate together in the sludge collection box 27. The stirring rod 39 is used to stir the accumulated shrimp shells to prevent them from clogging the drain hole due to accumulation, thus facilitating the smooth separation of water from the shrimp shells.

[0035] like Figure 10 As shown, a method for separating aquatic products, applicable to the aforementioned aquatic product separation device, includes the following steps: S1: Use the rubber pressure plate 5 to press down the headless freshwater shrimp, so that its back faces the side of the impact pipe 19 and its tail faces the side away from the feed pipe 15. Then use the cutting knife 11 to cut open the back of the freshwater shrimp. S2: Move the impact tube 19 toward the shrimp's back and use the high-pressure fine water jet from the impact tube 19 to impact the opening on the shrimp's back, thereby widening the opening and separating the shrimp meat from the shell. S3: Move the feeding tube 15 toward the shrimp tail until it comes into contact with the separated shrimp meat. Then, use negative pressure to suck up the shrimp meat and pull back the feeding tube 15 to separate the shrimp meat from the shell. S4: Place the shrimp meat in the collection box 21 for temporary storage, use the sludge collection box 27 to collect the shrimp shells, and use the sewage collection box 28 to collect the sewage.
