Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated food production, and more specifically, to a boiling device for prefabricated crayfish. Background Art

[0002] With the rapid development of the prefabricated food industry, prefabricated aquatic products such as crayfish are deeply loved by consumers due to their convenience, quickness, and stable taste. In the processing process of prefabricated crayfish, after the products are seasoned and packaged, they usually need to be boiled and sterilized to kill the microorganisms on the surface and inside of the package and ensure food safety. At the same time, the sealing performance of the package directly determines the shelf life and quality stability of the product. Therefore, leakage detection of the package before and after boiling is also an essential quality control link.

[0003] In the prior art, the package leakage detection and boiling sterilization treatment of prefabricated crayfish often belong to two independent work sections, and the degree of automatic connection is not high. The common practice is: first, use an independent airtightness detection device to sample or detect each vacuum package one by one, and the unqualified products detected are picked out and cleaned manually, and the qualified products are then transported to the boiling pot by a conveyor belt for sterilization. Although some improved devices simply combine the detection and conveying functions, there are still the following obvious technical deficiencies: One key deficiency of the prior art is that when it is detected that the package has leakage (such as loose sealing, pinhole breakage), the leaked liquid, grease or soup will directly pollute the tabletop of the detection station, the conveyor belt and even the surrounding environment. Due to the lack of timely and automatic cleaning and drying structures, these pollutants will be carried to the subsequent boiling sterilization link as the equipment runs or the manual cleaning is not timely, resulting in the contamination of the whole pot of boiling liquid, which not only affects the cleanliness of the subsequent batch of products, but may also cause cross-contamination and increase the food safety risk. At the same time, the manual cleaning efficiency is low and the labor intensity is high, which is difficult to meet the requirements of continuous and automatic production. Summary of the Invention

[0004] In order to overcome the defects of the prior art, the technical problem to be solved by the present invention is to provide a boiling device for prefabricated crayfish, which can overcome the problems in the prior art that during the package leakage detection of prefabricated crayfish, the leaked liquid is easy to pollute the detection station and the subsequent boiling link, causing cross-contamination and being difficult to clean automatically.

The first air pump and the airbag are connected by a connecting pipe.

[0007] In a preferred embodiment of the present invention, a detection camera is fixedly installed on the rear inner wall of the sealing detection cover, and two supplementary lights are fixedly installed on the rear inner wall of the sealing detection cover.

[0008] In a preferred embodiment of the present invention, a water pump is fixedly installed on the left side of the sealing detection cover, a water supply pipe is fixedly installed at the suction end of the water pump, a spray head is fixedly installed on the front side of the sealing detection cover, and the output end of the water pump is connected to the spray head.

[0009] In a preferred embodiment of the present invention, a second air pump is fixedly installed on the front side of the sealing detection cover, and a high-pressure nozzle is fixedly installed on the front side of the sealing detection cover. The second air pump and the high-pressure nozzle are connected through an air supply pipe.

[0010] In a preferred embodiment of the present invention, a fixing plate is fixedly installed on the top of the crayfish pre-cooked food packaging and conveying frame, an electric telescopic rod is fixedly installed on the front side of the fixing plate, and a push plate is fixedly installed at the output end of the electric telescopic rod.

[0011] In a preferred embodiment of the present invention, a lifting conveyor belt is provided on the inner side of the water-boiling cleaning frame, and multiple partition plates are fixedly installed around the outer circumference of the lifting conveyor belt.

[0012] In a preferred embodiment of the present invention, a second drain pipe is fixedly installed on the front side of the water-boiling cleaning frame, and a solenoid valve is fixedly installed on the outer side of the second drain pipe.

[0013] In a preferred embodiment of the present invention, the top of the water-boiling cleaning frame is provided with an air inlet, two fans are fixedly installed on the top of the water-boiling cleaning frame, a filter screen is fixedly installed on the top of the water-boiling cleaning frame, the lifting conveyor belt is Z-shaped, and multiple second drainage holes are opened on the outer side of the lifting conveyor belt.

[0014] In a preferred embodiment of the present invention, a connecting plate is fixedly installed on the right side of the crayfish pre-prepared food packaging conveyor frame, a transfer frame is fixedly installed on the right side of the connecting plate, a conveyor belt is rotatably installed on the inner side of the transfer frame, a drive motor is fixedly installed on the front side of the connecting plate, a turntable is fixedly installed at the output end of the drive motor, a negative pressure extraction pump is fixedly installed on the inner side of the turntable, multiple suction nozzles are provided on the turntable, the suction end of the negative pressure extraction pump is connected to the suction nozzles, a gantry frame is fixedly installed on the rear side of the connecting plate, two barcode scanning cameras are fixedly installed on the top inner wall of the gantry frame, a mounting support plate is fixedly installed on the top of the transfer frame, an electric push rod is fixedly installed on the right side of the mounting support plate, and a push plate is fixedly installed at the output end of the electric push rod.

[0015] The beneficial effects of this invention are as follows: The present invention provides a pre-cooked crayfish boiling device, (1) by connecting the boiling cleaning frame and the leakage detection frame in series and integrating the conveyor belt, push plate and lifting conveyor belt on the same production line, the continuous operation from packaging and conveying, automatic leakage detection to boiling sterilization and lifting drying is realized without manual intervention, which greatly shortens the production process and improves the overall efficiency. The sealing detection cover is equipped with a first air pump and an airbag. The expansion of the airbag applies uniform and controllable additional pressure to the packaging bag, making it easier for the pressure sensor to detect even minor leaks. At the same time, it works with a supplementary light and a detection camera to capture packaging deformation in real time, achieving dual judgment of "pressure change + image recognition". This effectively avoids missed detections and false detections by single-method detection and significantly improves the reliability of sealing detection. The sealing detection cover integrates a water pump, spray head, second air pump, and high-pressure nozzle. After leakage is detected, the surface of the packaging bag is automatically rinsed and quickly dried. The rinsing wastewater is discharged directionally through the first drain hole and the first drain pipe. Only after the packaging bag is dried can it be pushed to the boiling cleaning frame. This design avoids contamination of the subsequent boiling tank by the leaked liquid, while eliminating the need for manual cleaning steps, ensuring the cleanliness and continuous operation of the production line.

[0016] This device employs a Z-shaped lifting conveyor belt with multiple secondary drainage holes to effectively drain moisture. The product is then dried by a fan, ensuring the packaging surface remains dry. A turntable at the rear, combined with a negative pressure extraction pump and suction nozzle, automatically flips the packaging bag when the barcode camera cannot read the QR code on the bottom, enabling double-sided scanning and registration. This design achieves fully automated operation from boiling and drying to barcode traceability, eliminating the need for manual flipping or wiping, reducing labor intensity, ensuring product traceability, and meeting modern food processing requirements.

[0019] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1-8 As shown, the embodiment provides a pre-cooked crayfish boiling device, including a boiling and cleaning frame 1, a leak detection frame 2 fixedly installed on the front side of the boiling and cleaning frame 1, a pre-cooked crayfish packaging and conveying frame 3 fixedly installed on the front side of the leak detection frame 2, a conveyor belt 4 rotatably installed on the inner side of the pre-cooked crayfish packaging and conveying frame 3 for sequentially conveying vacuum-packed pre-cooked crayfish to be processed forward, a hydraulic telescopic rod 5 fixedly installed on the top of the leak detection frame 2, a pressure sensor 6 fixedly installed at the output end of the hydraulic telescopic rod 5, a sealing detection cover 7 fixedly installed at the bottom of the pressure sensor 6, a sealing rubber ring 8 fixedly installed at the bottom of the sealing detection cover 7, a plurality of first drainage holes 9 opened on the bottom inner wall of the leak detection frame 2, and a first drainage pipe 10 fixedly installed on the front side of the leak detection frame 2. When sterilizing pre-packaged crayfish in plastic packaging by boiling, the crayfish pre-packaged food is sequentially conveyed by the conveyor belt 4 within the crayfish pre-packaged food conveyor frame 3. The electric telescopic rod 23 drives the pusher plate 24 to move the packaging bag, which can then be moved onto the leakage detection frame 2. The hydraulic telescopic rod 5 is activated, causing the pressure sensor 6, sealing detection cover 7, and sealing ring 8 to descend. The first air pump 11 is activated to supply air to the airbag 12, which presses down on the packaging bag. If the packaging bag is not sealed tightly or is broken, the pressure inside the bag will leak under pressure. The detection camera 14 can capture images to detect the leak. If a leak occurs, it can be cleared by the water pump 16. Water is supplied to the spray head 18, which sprays and rinses the bag. The water can be discharged through the first drain hole 9 and the first drain pipe 10, and then quickly dried by the second air pump 19 and the high-pressure nozzle 20. The bag can then be removed by personnel. The sealing detection cover 7 and the sealing ring 8 prevent liquid leakage. In this embodiment, the first air pump 11 is fixedly installed on the right side of the sealing detection cover 7, and the airbag 12 is fixedly installed on the top inner wall of the sealing detection cover 7. The first air pump 11 and the airbag 12 are connected by the connecting pipe 13. This structure allows the airbag 12 to expand evenly and apply stable pressure to the surface of the bag, avoiding excessive local pressure that could damage the bag.

[0021] Please see Figure 5As shown, a detection camera 14 is fixedly installed on the rear inner wall of the sealing detection cover 7, and two supplementary lights 15 are fixedly installed on the rear inner wall of the sealing detection cover 7. The supplementary lights 15 are automatically turned on during detection. In this embodiment, a water pump 16 is fixedly installed on the left side of the sealing detection cover 7, and a water supply pipe 17 is fixedly installed at the suction end of the water pump 16. A spray head 18 is fixedly installed on the front side of the sealing detection cover 7. The output end of the water pump 16 is connected to the spray head 18. When a defective product is detected, the water pump 16 is immediately started, and external cleaning water or disinfectant is sprayed onto the packaging surface through the spray head 18 to effectively remove the material and oil stains that have seeped out due to leakage, and prevent pollutants from remaining and spreading in the equipment.

[0022] In this embodiment, a second air pump 19 is fixedly installed on the front side of the sealing detection cover 7, and a high-pressure nozzle 20 is fixedly installed on the front side of the sealing detection cover 7. The second air pump 19 and the high-pressure nozzle 20 are connected through an air supply pipe 21. When the second air pump 19 is started, the high-pressure nozzle 20 sprays high-speed compressed air to quickly dry the moisture on the packaging surface and the inner wall of the sealing detection cover. In this embodiment, a fixed plate 22 is fixedly installed on the top of the crayfish pre-cooked food packaging conveyor frame 3. An electric telescopic rod 23 is fixedly installed on the front side of the fixed plate 22. A push plate 24 is fixedly installed on the output end of the electric telescopic rod 23. The electric telescopic rod 23 controls the pushing stroke according to the controller command to smoothly push the packaging bag on the conveyor belt 4 into the detection station of the leakage detection frame 2. After the detection is completed, the qualified product is pushed into the boiling and cleaning frame 1 to realize automatic circulation.

[0023] Please see Figure 7 As shown, a lifting conveyor belt 25 is provided on the inner side of the boiling cleaning frame 1, and multiple partition plates 26 are fixedly installed around the outer side of the lifting conveyor belt 25. The partition plates 26 are evenly distributed and separate each crayfish pre-cooked food package during the lifting process to prevent them from sticking together or stacking. In this embodiment, a second drainage pipe 27 is fixedly installed on the front side of the boiling cleaning frame 1, and a solenoid valve 28 is fixedly installed on the outer side of the second drainage pipe 27. The solenoid valve 28 can be automatically opened periodically to discharge the wastewater used in the boiling tank through the second drainage pipe 27, while replenishing fresh hot water.

[0024] In this embodiment, the top of the boiling cleaning frame 1 is provided with an air inlet, and two fans 30 are fixedly installed on the top of the boiling cleaning frame 1. A filter screen 31 is fixedly installed on the top of the boiling cleaning frame 1. After the test is completed, the push plate 24 is driven by the electric telescopic rod 23 to continue pushing. The push plate 24 can push the packaging bag into the boiling cleaning frame 1 for boiling sterilization. The lifting conveyor belt 25 and the partition plate 26 can lift and transport the sterilized packaging bag. After the fans 30 are started, they can blow the liquid on the packaging bag off. The liquid can flow into the boiling cleaning frame 1 through the second drain hole 29 to prevent liquid loss. The filter screen 31 can filter the dust and impurities entering the airflow of the fans to avoid secondary pollution to the packaging surface. In this embodiment, the lifting conveyor belt 25 is Z-shaped, and multiple second drain holes 29 are opened on the outer side of the lifting conveyor belt 25. A connecting plate 32 is fixedly installed on the right side of the pre-packaged crayfish conveyor frame 3. A transfer frame 33 is fixedly installed on the right side of the connecting plate 32. A conveyor belt 40 is rotatably installed on the inner side of the transfer frame 33. A drive motor 34 is fixedly installed on the front side of the connecting plate 32. A turntable 35 is fixedly installed at the output end of the drive motor 34. A negative pressure extraction pump 36 is fixedly installed on the inner side of the turntable 35. Multiple suction nozzles 37 are provided on the turntable 35. The suction end of the negative pressure extraction pump 36 is connected to the suction nozzles 37. A gantry frame 38 is fixedly installed on the rear side of the connecting plate 32. Two barcode scanning cameras 39 are fixedly installed on the top inner wall of the gantry frame 38. A mounting support plate 41 is fixedly installed on the top of the transfer frame 33. An electric push rod 42 is fixedly installed on the right side of the mounting support plate 41. A push plate 43 is fixedly installed at the output end of the electric push rod 42. After the electric push rod 42 is started, it can push the packaging bag on the conveyor belt 40 to the turntable 35 through the push plate 43. The barcode scanning camera 39 can scan and register the QR code on the packaging bag. If the QR code is on the other side of the packaging bag, the negative pressure extraction pump 36 is started to extract negative pressure to the suction nozzle 37. The suction nozzle 37 can adsorb the packaging bag, and the drive motor 34 is started to drive the turntable 35 and the packaging bag to flip. The turntable 35 is hollow, so that the barcode scanning camera 39 can scan the QR code on the other side of the packaging bag. After scanning, the drive motor 34 drives the turntable 35 to reset, and the electric push rod 42 drives the push plate 43 to move and push the packaging bag onto the conveyor belt 4.

[0025] This device automates the entire process of pre-packaged crayfish, from conveying, leak detection, washing and drying, boiling sterilization, lifting and draining, surface drying to automatic barcode scanning and transfer. The tightly integrated functional modules effectively reduce manual intervention and the labor intensity of operators, while improving the accuracy of packaging seal detection and production efficiency. The dual detection method of airbag pressurization and visual imaging within the seal detection hood 7 effectively avoids misjudgments or omissions that may occur with single detection methods. Spray rinsing and high-pressure drying functions ensure that defective products are cleaned before removal, preventing the spread of contaminants within the workshop. The Z-shaped lifting conveyor belt 25, combined with the drying design of the fan 30, saves water resources and ensures the dryness of the packaging surface, facilitating subsequent packaging or boxing processes. The automatic flip-and-scan barcode scanner at the rear solves the problems of low efficiency and easy omissions associated with traditional manual flip-and-scan barcode scanning, achieving product information traceability.

[0026] The overall effect achieved by the organization is as follows: First, the feeding and conveying process begins. The operator places the vacuum-packed crayfish pre-cooked dishes to be processed evenly and stably on the conveyor belt 4 inside the crayfish pre-cooked dish packaging conveyor frame 3, with the sealed side of the packaging facing upwards. A uniform gap is left between adjacent packages to avoid stacking and squeezing. The conveyor belt 4 is started, which drives the crayfish pre-cooked dish packaging towards the leak detection frame 2 at a uniform speed. When the packaging reaches the leak detection station, the conveyor belt 4 automatically stops, so that the packaging stops precisely under the sealing detection cover 7, completing the feeding and conveying process. Next, the sealing chamber is formed and pressurized for testing. The hydraulic telescopic rod 5 is activated, causing the pressure sensor 6, sealing detection cover 7, and sealing ring 8 to move downwards synchronously until the sealing ring 8 is tightly fitted against the surface of the leakage detection frame 2, forming a sealed detection chamber. The pressure sensor 6 monitors the downward pressure in real time. When the preset threshold is reached, the hydraulic telescopic rod 5 automatically stops and locks, ensuring the chamber is completely sealed and there is no gas or liquid leakage. Then, the first air pump 11 is activated, inflating the airbag 12 inside the sealing detection cover 7 through the connecting pipe 13. The airbag 12 slowly expands, creating uniform downward pressure on the pre-prepared crayfish packaging below. Compared to a rigid pressure plate, this airbag pressurization method better adapts to uneven packaging surfaces, achieving uniform pressure without damage. The pressure sensor 6 monitors the pressure changes within the chamber in real time. If the packaging has a false seal, pinholes, or damage, the gas inside will leak under pressure, causing abnormal pressure fluctuations within the chamber. The controller automatically determines the product as unqualified based on the pressure change rate threshold. If the pressure remains stable (pressure drop within the allowable range), it is preliminarily determined to be a qualified product. While performing pressure testing, a visual verification test is conducted. The supplementary light 15 inside the sealed detection cover 7 and the detection camera 14 are activated to take high-definition pictures of the packaging surface. The visual recognition system detects whether the packaging has defects such as damage, leakage, or bulging. The pressure test results are then verified a second time. This dual guarantee of "pressure change + image recognition" can effectively avoid missed or false detections that may occur with a single detection method. If the pressure test is qualified but the visual recognition finds a slight bulge, the system can still determine that it is unqualified, and vice versa. Based on the test results, the non-conforming product handling process is implemented. Water pump 16 is started, and clean water is drawn through water supply pipe 17. The non-conforming packaging is thoroughly sprayed and rinsed through spray head 18 to remove leaked liquid and oil stains from the packaging surface. The wastewater generated during rinsing is collected through the first drain hole 9 at the bottom of the leak detection frame 2 and discharged and recycled through the first drain pipe 10. After rinsing, the second air pump 19 is started, and high-pressure airflow is supplied to the high-pressure nozzle 20 through air supply pipe 21 to rapidly dry the rinsed non-conforming packaging under high pressure. This restores the packaging surface to a dry state, making it easy for operators to safely remove without getting contaminated with liquid. After drying, the hydraulic telescopic rod 5 drives the sealing detection cover 7 to rise and reset. The operator then removes the non-conforming product from the testing station for scrapping or rework. If the product is deemed qualified, it will undergo a process of transfer and boiling sterilization. The hydraulic telescopic rod 5 will cause the sealing detection cover 7 to rise and reset, and the electric telescopic rod 23 on the top fixed plate 22 of the crayfish pre-prepared food packaging conveyor frame 3 will be activated, causing the push plate 24 to move forward. The qualified crayfish pre-prepared food packaging will be smoothly pushed from the leakage detection frame 2 to the boiling cleaning frame 1 at the rear, completing the transfer of qualified products. The qualified products pushed into the boiling cleaning frame 1 will fall into the constant temperature sterilization boiling tank to complete the preset boiling sterilization and disinfection, thoroughly killing microorganisms on the packaging surface and ensuring food safety. After sterilization, the product is lifted, drained, and air-dried. It falls onto the Z-shaped lifting conveyor belt 25 inside the boiling cleaning frame 1. Adjacent partitions 26 separate and limit the product to prevent it from stacking or slipping. The lifting conveyor belt 25 lifts the product upward. During the lifting process, water stains on the product surface flow back into the boiling tank of the boiling cleaning frame 1 through the second drain hole 29 on the lifting conveyor belt 25, preventing water loss and reducing the burden of subsequent air drying. When the product is conveyed to the top discharge end of the lifting conveyor belt 25, the two fans 30 at the top of the boiling cleaning frame 1 are activated. The high-pressure airflow generated by the fans 30 is filtered by the filter screen 31 and blown onto the product surface to completely blow off the water stains remaining on the product surface, completing the surface air drying of the product. The air-dried product is discharged from the discharge end of the lifting conveyor belt 25 and enters the next process.
