Description

Technical Field

[0001] The invention relates to the technical field of fish processing, in particular to a fish processing technology. Background Art

[0002] In the modern food processing industry, fish products are deeply loved by consumers for their rich nutrition and delicious taste. However, traditional fish processing technology often has many problems, which restricts the improvement of production efficiency and product quality. In the past, fish descaling, cutting and other processing links mostly relied on manual operation, which was not only labor-intensive but also inefficient. Due to the instability of manual operation, the processing effect of fish is uneven, and it is easy to have problems such as incomplete descaling and uneven cutting, which affects the appearance and quality of the product.

[0003] There are many existing technologies for fish processing, such as:

[0004] Chinese patent publication number CN215302743U discloses a fish processing cutting device, which includes a bottom plate, the right end of the top of the bottom plate is connected to the side plate, the left side of the side plate is detachably connected to multiple horizontal plates, the center of the horizontal plate is provided with an opening that penetrates itself, the left position of the top of the horizontal plate is provided with an opening, the opening is slidably connected to a pull plate, the pull plate extends into the horizontal plate cavity through the opening, the bottom of the pull plate is connected to a clamping plate, the clamping plate penetrates the inner wall of the horizontal plate and extends into the opening, the left end of the clamping plate is connected to a spring, the left end of the spring is connected to the inner wall of the horizontal plate, the left end of the top of the bottom plate is slidably connected to a connecting plate, and cutting knives are provided at equal intervals on the right side wall of the connecting plate. The utility model realizes the rapid segmentation of fish, can adjust the segment length, and can well fix the fish body, ensuring the segmentation effect.

[0005] It can be seen that when processing most fish, the fish is placed in the clamping plate by pulling the pull plate, the fish is clamped, and then the fish is cut into sections by a cutting knife. This will not only increase the workload of fish processing and reduce the efficiency of fish processing, but also reduce the fit of the fish clamping, which can easily cause damage to the fish body during the cutting process, affecting the quality of fish processing, and also reduce the stability of the fish clamping, resulting in mistakes in the fish processing process, greatly reducing the practicability of the fish processing equipment, thereby causing economic losses.

[0006] In view of this, we propose a fish processing technology. Summary of the invention

[0013] S5. Marinating: Use an automatic stirring marinating device to evenly mix the fish segments with the pre-prepared marinade to ensure that the fish segments fully absorb the flavor of the marinade;

[0014] S6. Packing: After marinating, use a vacuum packaging machine to package the marinated fish;

[0015] Among them, the scaling and segmenting machine includes a transmission shell and a support shell. A conveyor belt is arranged inside the transmission shell. On both sides of the inner wall of the transmission shell near one end of the support shell, there are turning plates that can turn the fish over.

At both ends of the clamping knife close to the telescopic rod side, there are connecting shafts. One end of the connecting shaft away from the clamping knife is provided with an elastic member. One end of the elastic member away from the connecting shaft is fixedly connected to the interior of the mounting shell.

[0019] As a further improvement of the present technical solution, the cutting component at least includes a mounting box. Inside the mounting box, there is a second multi-stage hydraulic cylinder. The piston rod of the second multi-stage hydraulic cylinder is provided with a mounting rack.

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] Embodiment

[0042] Please refer to Figures 1 - 5 As shown, the purpose of this embodiment is to provide a fish processing technology, including the following steps:

[0043] Step 1. Killing fish and preliminary rinsing: Place the fish to be processed on the conveyor belt in an orderly manner. When the fish is transported to the area of the electric slaughtering tool, the sensor will detect the position and size of the fish, and use the electric slaughtering tool to cut off the artery of the fish gill under the command of the intelligent control system. Subsequently, the fish is preliminarily rinsed with a high-pressure water gun to remove the obvious dirt and blood on the fish surface;

[0044] Step 2. Scaling and cutting segments: The fish after preliminary rinsing is sent into the scaling and cutting segment machine by the conveyor belt. When the scaling and cutting segment machine is started and the fish is pulled into the interior of the scaling and cutting segment machine, the fish is scaled and clamped, and then the fish is cut into segments;

[0045] Step 3. Cleaning fish: The fish after scaling and cutting segments is pushed into the interior of the cleaning pool 30, and the cleaning device sprays clean water from multiple nozzles at multiple angles to clean the fish segments and remove the remaining fish scales, blood and impurities;

[0046] Step 4. Drying: The cleaned fish segments are placed on a well-ventilated drying rack, and a fan or ventilation system is used to accelerate the air flow to quickly evaporate the moisture on the surface of the fish segments;

[0047] Step 5. Marinating: Use an automatic stirring marinating device to evenly mix the fish segments with the pre-prepared marinade to ensure that the fish segments fully absorb the taste of the marinade;

[0048] Step 6. Packaging: After pickling is completed, the pickled fish segments are packaged using a vacuum packaging machine. The vacuum packaging machine can quickly extract the air inside the package to form a vacuum environment, effectively preventing the intrusion of external oxygen and microorganisms. The packaging materials used all strictly comply with food hygiene standards, have good barrier properties and freshness preservation effects, can maximize the shelf life of the product, and ensure the quality and safety of the product during storage and transportation;

[0049] Among them, the scale-removing and segmenting machine includes a conveying shell 10 and a supporting shell 20. A conveyor belt 11 is arranged inside the conveying shell 10. On both sides of the inner wall of the conveying shell 10 near one end of the supporting shell 20, there are turnover plates 12 that can turn the fish over. At one end of the bottom of the conveying shell 10 near the supporting shell 20, there is a pushing component 13, and the pushing component 13 can push the segmented fish into the inside of the cleaning pool 30;

[0050] At the opening of the supporting shell 20, there is a shell 21. On both sides inside the shell 21, there are multiple pairs of clamping components 22. Inside the shell 21, there is a segmenting component 23 that can segment the fish, and at one end of the inside of the shell 21 far from the conveying shell 10, there is a pulling component 24;

[0051] The pulling component 24 can clamp the fish tail and pull the turned-over fish through the clamping components 22. At the same time, the fish scales are removed through the clamping components 22, and the fish with scales removed is clamped.

[0052] Since the body shapes of fish present various forms, such as common spindle-shaped fish, laterally compressed fish, etc., there are differences in their thicknesses; when dealing with the scale-removing of fish, if different arc-shaped scale-removing tools are used for fish with different thicknesses, this will not only greatly increase the usage cost of the scale-removing and segmenting machine, seriously reduce its flexibility in use, but also have an adverse impact on the working efficiency of fish processing. Therefore, according to Figure 3 、 Figure 5 and Figure 7 as shown, the specific structure of the clamping component 22 is disclosed. The clamping component 22 includes at least two mounting shells 221. In the middle of the interiors of the two mounting shells 221, there is a telescopic rod 222. Inside the two mounting shells 221, there are support plates 223 that can support the telescopic rod 222. At the end of the telescopic rod 222 far from the inside of the mounting shell 221, there is a clamping knife 224. The clamping knife 224 has an elastic function. At both ends of the clamping knife 224 near the telescopic rod 222, there are connecting shafts 225. At the end of the connecting shaft 225 far from the clamping knife 224, there is an elastic member 226. The end of the elastic member 226 far from the connecting shaft 225 is fixedly connected to the inside of the mounting shell 221.

[0053] When the pulling assembly 24 passes through the multiple pairs of clamping assemblies 22, the elastic member 226 is deformed and stretched. When the tail of the fish is clamped and the fish is pulled, the clamping knife 224 is pushed toward the fish by the resilience of the elastic member 226, and the scales of the pulled fish are removed by the inclined clamping knife 224. The fish after the scales are removed is clamped by the clamping knife 224. At this time, the fish can be cut into sections, and the two elastic members 226 on one side of the clamping knife 224 can adjust the clamping knife 224 according to the thickness of the fish. 24, at the same time, the telescopic rod 222 not only performs telescopic work to assist the clamping knife 224 to move its position, but also can support the clamping knife 224, and through the coordinated work of the elastic member 226 and the telescopic rod 222, the descaling and cutting operations are made smoother, the probability of operational errors is reduced, the quality stability of the product is improved, and it can also adapt to fish of different sizes and shapes, thereby improving the versatility and application range of the descaling and cutting machine, thereby improving the flexibility of the use of the descaling and cutting machine.

[0054] In the process of fish processing, if the cutting work cannot be completed in one go, it will not only affect the quality of the fish products, but also reduce the efficiency of the production process. Figure 3 and Figure 6 It can be known that the specific structure of the segmentation component 23 is disclosed, and the segmentation component 23 at least includes a mounting box 231, a second multi-stage hydraulic cylinder 232 is arranged inside the mounting box 231, the piston rod of the second multi-stage hydraulic cylinder 232 is provided with a mounting frame 233, and a plurality of segmentation knives 234 are arranged on the side of the mounting frame 233 close to the second multi-stage hydraulic cylinder 232.

[0055] The second multi-stage hydraulic cylinder 232 is powered on to make it work, and the mounting frame 233 is moved toward the inner wall of the shell 21 through the pushing work of the piston rod of the second multi-stage hydraulic cylinder 232. At this time, the fish can be pulled into the interior of the clamping assembly 22, and the cutting knife 234 is moved toward the clamped fish for cutting by resetting the piston rod of the second multi-stage hydraulic cylinder 232, thereby effectively ensuring that the moving distance and force of the cutting knife 234 are accurate, improving the accuracy and consistency of the cutting, making the size of each piece of fish more uniform, improving the quality of the product, and being able to complete the cutting work at one time, greatly reducing the time and labor cost of repeated operations, thereby improving the production efficiency of fish processing.

[0056] In order to allow the fish to be cut into segments to enter the descaling and segmenting machine for processing, therefore, according to Figure 3 , Figure 4 , Figure 5 and Figure 9It can be known that the specific structure of the pulling component 24 is disclosed. The pulling component 24 at least includes a backing plate 241. A third multi-stage hydraulic cylinder 242 is arranged inside the housing 21. The third multi-stage hydraulic cylinder 242 is located on the upper surface of the backing plate 241. A connecting plate 243 is arranged on the piston rod of the third multi-stage hydraulic cylinder 242. An electric gripper 244 is arranged on the side of the connecting plate 243 away from the third multi-stage hydraulic cylinder 242.

[0057] Power on the third multi-stage hydraulic cylinder 242 and the electric gripper 244 to make them work. Through the push of the piston rod of the third multi-stage hydraulic cylinder 242, move the electric gripper 244 through the clamping component 22 towards the conveyor belt 11. Then, clamp the fish tail with the electric gripper 244. Through the reset work of the third multi-stage hydraulic cylinder 242, the fish to be scaled and cut sections enters the inside of multiple clamping components 22, playing an auxiliary role, improving the accuracy and stability of the fish entering the scaling and cutting machine, reducing processing errors caused by the position deviation of the fish, and also improving the fish production efficiency, thereby increasing economic benefits.

[0058] The sizes of the above-mentioned electric gripper 244 and the third multi-stage hydraulic cylinder 242 are relatively small, and the resistance of the clamping component 22 to the pulling component 24 when pulling the fish can be ignored. And Figure 3 、 Figure 4 、 Figure 5 and Figure 9 The sizes shown are for reference only. The working principle of the above-mentioned electric gripper 244: By means of motor drive or electromagnetic drive, control the opening and closing actions of the gripper. When receiving a clamping signal, the motor or electromagnetic device will generate corresponding power, causing the gripper to close, thus tightly clamping the object; when it needs to be released, the power acts in the reverse direction and the gripper opens.

[0059] Since the cut fish will be blocked by multiple pairs of clamping components 22, it is difficult to smoothly push the cut fish into the inside of the cleaning tank 30, which may lead to the interruption of the production process, increase the operation difficulty and labor intensity, thereby affecting the practicability of the scaling and cutting machine. Therefore, according to Figure 4 It can be known that the specific structure of the lifting component 26 is disclosed. A cylinder 261 is arranged inside the support shell 20. A lifting plate 262 is arranged on the piston rod of the cylinder 261.

[0060] Power on the cylinder 261 to make it work. Through the work of the piston rod of the cylinder 261 to push, move the lifting plate 262 closer to the clamping assembly 22. At this time, the work of cutting the fish can be carried out, which can effectively reduce the damage to the fish when the cut fish falls onto the lifting plate 262, ensuring the integrity of the fish segments to the greatest extent. Moreover, through the work of the piston rod of the cylinder 261 to reset, move the lifting plate 262 downward, creating good working conditions for the material pushing assembly 13, facilitating the smooth pushing of the cut fish into the inside of the cleaning tank 30; not only ensuring the continuity and stability of the production process, avoiding stagnation caused by poor pushing of fish segments; but also reducing the operation difficulty, lightening the labor intensity, and improving the work efficiency; also reducing the damage of fish segments and enhancing the product quality; thus improving the efficiency of fish processing.

[0061] In order not to affect the conveying process of the fish during processing and reduce the factors affecting the work efficiency of fish processing, therefore, according to Figure 4 it is known, and the specific structure of the material pushing assembly 13 is disclosed. The material pushing assembly 13 at least includes a mounting plate 131. A first multi-stage hydraulic cylinder 132 is arranged on one side of the mounting plate 131 close to the support shell 20, and a material pushing plate 133 is arranged on the piston rod of the first multi-stage hydraulic cylinder 132.

[0062] Power on the first multi-stage hydraulic cylinder 132 to make it work. Through the work of the piston rod of the first multi-stage hydraulic cylinder 132 to push, the material pushing plate 133 pushes the fish on the upper surface of the lifting plate 262 into the inside of the cleaning tank 30, which can quickly and powerfully push the cut fish towards the cleaning tank 30, greatly shortening the conveying time of the fish segments, and can also reduce manual intervention, reducing the possibility of human error, improving the accuracy and consistency of the work, thus improving the work efficiency and processing quality of fish processing.

[0063] During the process of the conveyor belt 11 conveying the fish, due to the impact force of the fish, in order to ensure that the fish can accurately enter the inside of the clamping assembly 22, therefore, according to Figure 2 、 Figure 3 and Figure 9 it is known that guide plates 25 are arranged on one side of two clamping knives 224 close to the telescopic rod 222 near the opening of the housing 21, and the guide plates 25 have an elastic function. With the help of the guide plates 25, the fish can accurately enter the clamping assembly 22; moreover, due to the elastic characteristics of the two guide plates 25, it can cause the guide plates 25 to deform synchronously with the deformation of the clamping knives 224, and can also effectively improve the accuracy and efficiency of the fish entering the clamping assembly 22, reducing the position deviation caused by the impact force of the fish, thus reducing the defective rate. And the elastic ability of the guide plates 25 enhances the flexibility and versatility of the clamping assembly 22, can cope with fish of different thicknesses, and improves the continuity and stability of fish production.

[0064] In summary, the working principle of this solution is as follows: First, power on the cylinder 261 to make it work. Through the work of the piston rod of the cylinder 261, the lifting plate 262 is pushed towards the clamping assembly 22, so that the upper surface of the lifting plate 262 closely fits the lower surface of the mounting shell 221. Also, power on the second multi-stage hydraulic cylinder 232 to make it work. Through the work of the piston rod of the second multi-stage hydraulic cylinder 232, the mounting bracket 233 is moved towards the inner wall of the housing 21.

[0065] After that, power on the conveyor belt 11 to make it work, and let the preliminarily rinsed fish flow into the interior of the housing 21. Before that, the preliminarily rinsed fish will pass through two flipping plates 12 to flip the fish on its side. The fish after being flipped on its side flows through the guiding plate 25 towards a pair of clamping assemblies 22 near the side opening of the housing 21. At the same time, power on the third multi-stage hydraulic cylinder 242 and the electric gripper 244 to make them work. Through the work of the piston rod of the third multi-stage hydraulic cylinder 242, the electric gripper 244 is pushed through the clamping assembly 22 towards the conveyor belt 11. At the same time, the elastic member 226 deforms and expands. Then, the electric gripper 244 clamps the fish tail, and through the work of the third multi-stage hydraulic cylinder 242 to reset, the fish that needs to have its scales removed and be cut into sections enters the interior of multiple clamping assemblies 22. Through the resilience of the elastic member 226, the clamping knife 224 is pushed towards the fish. And because the clamping knife 224 is inclined, the pulled fish has its scales removed. After the scales are removed, the fish is clamped by the clamping knife 224.

[0066] Then, through the work of the piston rod of the second multi-stage hydraulic cylinder 232 to reset, the cutting knife 234 is moved towards the clamped fish to cut the fish into sections. After that, through the work of the piston rod of the cylinder 261 to reset, the lifting plate 262 is moved downward. At this time, power on the first multi-stage hydraulic cylinder 132 to make it work. Through the work of the piston rod of the first multi-stage hydraulic cylinder 132, the pushing plate 133 pushes the fish on the upper surface of the lifting plate 262 into the interior of the cleaning tank 30, and thus the work of removing scales and cutting sections of fish processing can be completed.

Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments.
