Description

Technical Field

[0001] This utility model belongs to the field of automated production line technology and relates to a seafood pre-processing production line. Background Technology

[0002] In the existing seafood pre-processing sector, traditional production lines typically employ a fixed process flow, where all raw materials sequentially undergo cleaning, steaming or pre-cooking, cooling, and freezing processes along a single path. This rigid structure struggles to adapt to the diverse processing and preservation needs of different types of seafood.

[0003] However, the existing equipment lacks a path switching mechanism, making it impossible to flexibly allocate processing and preservation paths on the same production line. This results in either the need to configure multiple independent production lines, increasing costs and floor space, or sacrificing the optimal process conditions for some products, affecting quality. In addition, poor coordination between processes and frequent material transfers also reduce overall production efficiency and increase the risk of cross-contamination.

[0004] Therefore, there is an urgent need for a pre-processed seafood production line with integrated structure and adjustable process, which can dynamically select processing and preservation paths according to actual needs, and achieve efficient, high-quality and flexible production. Summary of the Invention

The first output port can be selectively connected to either the first output port or the second output port. The second conveying section is provided with a second input port, a third output port, and a fourth output port. The second input port can be selectively connected to either the third output port or the fourth output port. The third conveying section includes a first output line and a second output line.

[0007] The processing mechanism includes a steaming component and a pre-cooking and cooling component. The first output port is connected to the input end of the steaming component, and the second output port is connected to the input end of the pre-cooking and cooling component. The output ends of the steaming component and the pre-cooking and cooling component are both connected to the second input port.

[0009] In the aforementioned seafood pre-processing production line, a branching component is also included. The branching component is respectively disposed in the first conveying section and the second conveying section. The branching component includes a branching guide rail and a rotating connection component. The branching guide rail is rotatably connected to the first conveying section and the second conveying section respectively through the rotating connection component.

[0010] In the aforementioned seafood pre-processing production line, the rotating connection assembly includes a clamping clamp, a connecting rod, and an adjusting rod. There are two rotating connection assemblies, located at both ends of the branch guide rail. The clamping clamp is connected to the branch guide rail. One end of the connecting rod is accommodated in the clamping clamp, and the other end of the connecting rod is detachably connected to the first conveying part. The adjusting rod passes through the clamping clamp and is used to control the tightness of the clamping clamp.

[0011] In the above-mentioned seafood pre-processing production line, the steaming component includes a first cavity, a heating element, and a water replenishment element. The inlet end of the first cavity is connected to the first outlet, the outlet end of the first cavity is connected to the second inlet, the output end of the water replenishment element is accommodated in the first cavity, and the heating element is used to heat water into steam and deliver it to the water replenishment element.

[0012] In the aforementioned seafood pre-processing production line, the steaming component further includes two air outlets, which are located at the top of both ends of the first cavity.

[0013] In the aforementioned seafood pre-processing production line, the pre-cooking and cooling assembly includes a pre-cooking machine, which comprises a second cavity, a third cavity, a steam unit, and a hot water conveying unit. The second cavity is located above the third cavity and is further provided with a first conveyor belt. The first conveyor belt is provided with a first conveying area and a second conveying area, the second conveying area being higher than the first conveying area. The steam unit is located in the third cavity. One end of the hot water conveying unit is connected to the second cavity, and the other end of the hot water conveying unit is connected to the third cavity.

[0014] In the aforementioned seafood pre-processing production line, the pre-cooking and cooling assembly includes a cooling machine, which comprises a fourth chamber, a second conveyor belt, a third conveyor belt, and a water spraying unit. Both the second and third conveyor belts are housed within the fourth chamber. The second conveyor belt includes a third conveying area and a fourth conveying area, with the fourth conveying area being higher than the third conveying area. The third conveyor belt is positioned above the third conveying area. The water spraying unit is located between the fourth and third conveying areas. The water spraying unit is used to spray water onto the food transported from the third conveying area to the fourth conveying area while simultaneously adding water to the fourth chamber. The fourth chamber also has a drain outlet, the height of which is positioned between the water spraying unit and the third conveyor belt, ensuring that the water level in the fourth chamber is higher than that on the third conveyor belt.

By cleverly setting up the first conveying section, the second conveying section, and the third conveying section, a highly flexible and dynamically adjustable material conveying system is constructed. It can selectively change the material conveying path according to actual processing needs, thereby achieving precise adaptation to different process flows.

[0020] 2. This dynamically adjustable branching component completely breaks away from the traditional fixed transmission system, effectively solving the problems of poor process adaptability and low production changeover efficiency caused by the rigid configuration of equipment in the past. The entire switching process can be completed in a few seconds without stopping the machine for adjustment, which greatly improves the response speed and flexible production capacity of the production line.

[0021] 3. This rotating connection component allows for the rotation and connection / disconnection of the branch guide rails without the need for additional tools, greatly simplifying on-site installation and subsequent maintenance. When it is necessary to replace the guide rails, clean the equipment, or adjust the conveying angle, simply loosen the adjusting rod to quickly disassemble the clamps. After replacing the parts or fine-tuning the angle, the clamps can be re-locked. The entire process requires no special tools or complex calibration, significantly reducing downtime.

[0039] The specific embodiments described herein are merely illustrative examples of this utility model patent. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or adopt similar methods to replace them, but without departing from the patent of this utility model or exceeding the scope defined by the appended claims.

[0040] like Figures 1-10 As shown, a seafood pre-processing production line includes: a conveying mechanism 1, a processing structure, and a preservation mechanism 3.

[0041] The conveying mechanism 1 includes a first conveying section 11, a second conveying section 12, and a third conveying section 13. The first conveying section 11 is provided with a first input port 111, a first output port 112, and a second output port 113. The first output port 112 can be selectively connected to either the first output port 112 or the second output port 113. The second conveying section 12 is provided with a second input port 121, a third output port 122, and a fourth output port 123. The second input port 121 can be selectively connected to either the third output port 122 or the fourth output port 123. The third conveying section 13 includes a first output line 131 and a second output line 132.

[0042] The processing mechanism 2 includes a steaming component 21 and a pre-cooking and cooling component 22. The first output port 112 is connected to the input end of the steaming component 21, and the second output port 113 is connected to the input end of the pre-cooking and cooling component 22. The output ends of the steaming component 21 and the pre-cooking and cooling component 22 are both connected to the second input port 121.

[0043] The preservation mechanism 3 includes a quick-freezing machine 31 and a thawing machine 32. The third output port 122 is connected to the input end of the quick-freezing machine 31, the output end of the quick-freezing machine 31 is connected to the first output line 131, the fourth output port 123 is connected to the input end of the thawing machine 32, and the output end of the thawing machine 32 is connected to the second output line 132.

[0044] Specifically, by cleverly setting up the first conveying section 11, the second conveying section 12, and the third conveying section 13, different conveying routes can be adjusted. On this basis, the steaming component 21 and the pre-cooking and cooling component 22 are integrated to form two parallel and non-interfering processing paths. Furthermore, the system is connected to the quick-freezing machine 31 and the aging machine 32 at the end, so that the products output from different pre-treatment paths can enter the corresponding freezing or aging treatment units according to their physicochemical properties and preservation requirements.

[0045] In this embodiment, the seafood pre-processing production line adopts a modular design. By cleverly setting up the first conveying section 11, the second conveying section 12 and the third conveying section 13, a highly flexible and dynamically adjustable material conveying system is constructed. It can selectively change the material conveying path according to actual processing needs, thereby achieving precise adaptation to different process flows.

[0046] like Figures 1-10 As shown, based on the above embodiment, a branching component 14 is also included. The branching component 14 is respectively disposed on the first conveying part 11 and the second conveying part 12. The branching component 14 includes a branching guide rail 141 and a rotating connection component 142. The branching guide rail 141 is rotatably connected to the first conveying part 11 and the second conveying part 12 respectively through the rotating connection component 142.

[0047] Specifically, a branching assembly 14 is added to the first conveying section 11 and the second conveying section 12. The branching assembly 14 consists of a branching guide rail 141 and a rotating connection assembly 142. By rotating the connection assembly 142, the direction of the branching guide rail 141 is adjusted, thereby changing the connection between the first input port 111 and the first output port 112 or the second output port 113 on the first conveying section 11, and the connection between the second input port 121 and the third output port 122 or the fourth output port 123 on the second conveying section 12.

[0048] In this embodiment, the dynamically adjustable branching component 14 completely breaks away from the traditional fixed transmission system, effectively solving the problems of poor process adaptability and low production changeover efficiency caused by the rigid configuration of equipment in the past. The entire switching process can be completed in a few seconds without stopping the machine for adjustment, which greatly improves the response speed and flexible production capability of the production line.

[0049] like Figures 1-10 As shown, based on the above embodiment, the rotating connection assembly 142 includes a clamping clamp 1421, a connecting rod 1422, and an adjusting rod 1423. There are two rotating connection assemblies 142, located at both ends of the branch guide rail 141. The clamping clamp 1421 is connected to the branch guide rail 141. One end of the connecting rod 1422 is accommodated in the clamping clamp 1421, and the other end of the connecting rod 1422 is detachably connected to the first conveying part 11. The adjusting rod 1423 passes through the clamping clamp 1421 and is used to control the tightness of the clamping clamp 1421.

[0050] Specifically, the rotating connection assembly 142 is composed of three parts: a clamping clamp 1421, a connecting rod 1422, and an adjusting rod 1423, which are symmetrically arranged at both ends of the branch guide rail 141. The connecting rod 1422, as the main load-bearing member, not only provides structural support, but also gives the assembly the necessary rotational freedom through its hinged design with the clamping clamp 1421. The operator can manually adjust the opening and closing degree of the clamping clamp 1421 through the adjusting rod 1423, thereby controlling the clamping tightness of the connecting rod 1422.

[0051] In this embodiment, the rotating connection component 142 allows for the rotation and connection / disconnection of the branch guide rail 141 without the need for additional tools, greatly simplifying the on-site installation and subsequent maintenance process. When it is necessary to replace the guide rail, clean the equipment, or adjust the conveying angle, the clamping clamp 1421 can be quickly disassembled simply by loosening the adjusting rod 1423. After the component replacement or angle fine adjustment is completed, it can be re-locked. The entire process does not require special tools or complex calibration, significantly reducing downtime.

[0052] like Figures 1-10 As shown, based on the above embodiment, the steaming assembly 21 includes a first cavity 211, a heating element (not shown in the figure), and a water supply element 212. The inlet end of the first cavity 211 is connected to the first outlet 112, and the outlet end of the first cavity 211 is connected to the second inlet 121. The output end of the water supply element 212 is accommodated in the first cavity 211, and the heating element is used to heat water into steam and deliver it to the water supply element 212.

[0053] In this embodiment, the first cavity 211 serves as the core steaming space, possessing excellent heat insulation performance and effectively reducing heat loss. The heating element can quickly convert liquid water into saturated steam, while the water replenishment element 212 can transport the steam generated by the heating element to the first cavity 211, thereby enabling the seafood in the first cavity 211 to be steamed. This steaming assembly 21, through an integrated technical approach, can complete the steaming of seafood on one of the branch lines in the processing unit.

[0054] like Figures 1-10 As shown, based on the above embodiment, the steaming component 21 further includes two air outlets 213, which are located at the top of both ends of the first cavity 211.

[0055] Specifically, two air outlets 213 are symmetrically arranged at the top of both ends of the first cavity 211. The dual air outlet 213 layout can not only discharge excess steam generated during the steaming process in a timely and efficient manner, effectively preventing abnormal pressure rise caused by steam accumulation in the cavity, thereby avoiding potential safety risks and equipment sealing failure, but more importantly, its high-position arrangement at both ends of the cavity cleverly utilizes the physical characteristics of natural rise and convection diffusion of hot steam to form a directional airflow path from the central heating zone to the top of both sides.

[0056] In this embodiment, this structure enables steam to circulate more fully and evenly within the cavity. Fresh, high-temperature steam is continuously generated from the bottom or side wall heating area, then diffuses upwards and to both ends, before being orderly discharged through the top air outlet 213. This establishes a dynamically balanced airflow field within the cavity, ensuring that the entire batch of seafood is heated consistently and cooked evenly.

[0057] like Figures 1-10 As shown, based on the above embodiment, the pre-cooking and cooling assembly 22 includes a pre-cooking machine 221. The pre-cooking machine 221 includes a second chamber 2211, a third chamber 2212, a steam unit 2213, and a hot water delivery unit (not shown in the figure). The second chamber 2211 is located above the third chamber 2212. The second chamber 2211 is also provided with a first conveyor belt 2214. The first conveyor belt 2214 is provided with a first conveying area 2215 and a second conveying area 2216. The second conveying area 2216 is higher than the first conveying area 2215. The steam unit 2213 is located in the third chamber 2212. One end of the hot water delivery unit is connected to the second chamber 2211, and the other end of the hot water delivery unit is connected to the third chamber 2212.

[0058] Specifically, the precooking machine 221 in the precooking and cooling assembly 22 adopts an innovative upper and lower double-chamber structure. The third chamber 2212 has a steam unit 2213, which can heat the water in the third chamber 2212 through heat exchange. The heated water in the third chamber 2212 is then transported to the second chamber 2211 through the hot water conveying unit. The second chamber 2211 is finely divided into two high and low conveying areas, forming a continuous processing flow of "immersion cooking - draining". In the constant temperature water bath of the first conveying area 2215, the seafood raw materials are completely immersed in hot water to achieve rapid and uniform precooking and shaping. Subsequently, the material rises steadily with the conveyor belt to the second conveying area 2216, where it leaves the water surface for natural draining and residual heat release, effectively removing surface water.

[0059] In this embodiment, the third chamber 2212 provides hot water to the second chamber 2211, which not only achieves gentle, precise and efficient heat treatment, but also significantly reduces the risk of seafood skin cracking, excessive protein denaturation or aging of taste due to local overheating. This is achieved by abandoning the traditional heating method of direct open flame or direct insertion of electric heating tube into the water, and instead using a closed steam unit 2213 set at the bottom or side wall of the chamber to indirectly heat the water.

[0060] like Figures 1-10 As shown, based on the above embodiment, the pre-cooking and cooling assembly 22 includes a cooling machine 222, which includes a fourth chamber 2221, a second conveyor belt 2222, a third conveyor belt 2223, and a water spray unit 2224. The second conveyor belt 2222 and the third conveyor belt 2223 are both housed within the fourth chamber 2221. The second conveyor belt 2222 includes a third conveying area 2225 and a fourth conveying area 2226. The fourth conveying area 2226 is higher than the third conveying area 2225, and the third conveyor belt 2223 is disposed within the third conveying area. Above 2225, the water spray unit 2224 is disposed between the fourth conveying area 2226 and the third conveying area 2225. The water spray unit 2224 is used to spray water to clean the food transported from the third conveying area 2225 to the fourth conveying area 2226, while adding water to the fourth cavity 2221. The fourth cavity 2221 is also provided with a drain outlet 2227. The height of the drain outlet 2227 is set between the water spray unit 2224 and the third conveyor belt 2223, so that the water level in the fourth cavity 2221 is higher than that in the third conveyor belt 2223.

[0061] Specifically, the pre-cooked seafood first enters the third conveyor zone 2225 of the second conveyor belt 2222. Since the third conveyor zone 2225 is located in water, the seafood can be initially soaked and cooled. The third conveyor belt 2223 above the third conveyor zone 2225 can push the seafood floating on the water back into the water and continue to transport it. During the process of transporting the seafood from the third conveyor zone 2225 to the fourth conveyor zone 2226, a water spray unit 2224 is also set up. On the one hand, it quickly cools down the high-temperature food, promotes its rapid shaping, and locks in the internal moisture and flavor. On the other hand, it uses the water flow to effectively remove the surface foam, debris, mucus and other processing attachments, achieving simultaneous cleaning. Since the water level at the drain outlet 2227 is controlled, the newly added spray water can continuously replace the old water, pushing the water flow to form a one-way micro-circulation along the conveying direction, and cooperating with the bottom drain outlet 2227 to discharge the turbid water.

[0062] In this embodiment, the structure of the cooler 222 achieves a four-fold synergistic effect of "simultaneous conveying, spraying, immersion cooling, and sewage discharge", which not only significantly shortens the cooling time and increases production capacity, but also enhances the sensory quality and hygiene safety of the product at the physical level.

[0063] like Figures 1-10 As shown, based on the above embodiment, the quick-freezing machine 31 is provided with a fifth cavity 311 and a quick-freezing unit 312. The quick-freezing unit 312 is located below the fifth cavity 311 and is used to quick-freeze the food passing through the fifth cavity 311.

[0064] In this embodiment, the quick-freezing unit 312 is placed below the fifth chamber 311 in the quick-freezing machine 31. Cold air penetrates the food from bottom to top, forming a highly efficient convection freezing mechanism. This highly efficient convection freezing mechanism greatly shortens the freezing time of food, thereby maximizing the protection of the original cell membrane integrity, tissue structure and water holding capacity of seafood, effectively preventing juice loss, soft texture or flavor deterioration after thawing, and thus highly preserving its natural freshness, elasticity and sensory quality.

[0065] like Figures 1-10 As shown, based on the above embodiment, the aging machine 32 is provided with a sixth chamber 321, a freezing unit 322 and a blowing unit 323. The freezing unit 322 and the blowing unit 323 are both located at the bottom of the sixth chamber 321. The sixth chamber 321 is also provided with an isolation net 324, which covers the top of the freezing unit 322 and the blowing unit 323.

[0066] In this embodiment, the slow-release machine 32 innovatively integrates a freezing unit 322 and a high-efficiency blowing unit 323 at the bottom of the sixth chamber 321. The freezing unit 322, as a cold source, is arranged at the bottom of the chamber and is physically isolated from the seafood materials on the conveyor belt by the isolation net 324 set above. The isolation net 324 not only effectively prevents the food from directly contacting the low-temperature metal surface and causing local freezing, frostbite or adhesion, but also ensures that the cold air diffuses upward evenly, avoiding quality fluctuations caused by uneven heating and cooling. The blowing unit 323 can blow the low-temperature air generated by the freezing unit 322 upward at a low speed and evenly to form a stable and gentle cold air circulation field, which can maintain the low-temperature freshness of the pre-treated food during short-term storage or waiting for processing.

[0067] like Figures 1-10 As shown, based on the above embodiment, a collection basket is also included, which is disposed at the end of the first output line 131 and the second output line 132.

[0068] In this embodiment, dedicated collection baskets are set at the ends of the first output line 131 and the second output line 132, which not only realizes the physical isolation and automatic classification of finished products produced by different process paths, effectively eliminating the risk of mixing materials due to human sorting oversights, but also significantly simplifies the operation process of the unloading process. Each collection basket can be used as an independent quality control unit, and can be bound to information such as the processing time, process parameters, and raw material batch of the product it carries, forming a complete data chain "from production line to warehouse".
