Description

Technical Field

[0001] This invention relates to the field of conveyor lines for braised products, and more specifically to an automated conveyor production line for braised products. Background Technology

[0002] Braised products are an important category in the food processing industry. Their production process includes core steps such as braising, draining, conveying, and unloading. Suspended conveyors have gradually become the mainstream conveying method for braised product production lines due to their small footprint and ability to operate continuously.

[0003] Currently, existing suspended conveyor systems for braised products mainly have the following defects:

[0004] 1. Limited functionality and serious dripping pollution: Existing braising baskets only have the functions of braising and simple unloading. After the food is taken out of the pot, the braising liquid and oil carried by the food will continue to drip from the surface of the basket, causing oil and soup accumulation on the ground, breeding mosquitoes, and serious odor. Although this can be alleviated by arranging liquid collection tanks throughout the line, the liquid collection tanks are prone to accumulating residue and are difficult to clean, thus becoming new hygiene dead spots, and cannot solve the dripping problem when transporting across clean areas.

[0005] 2. Complex structure, poor reliability, and prominent hygiene hazards: In order to achieve functions such as flipping and drip prevention, some baskets have built-in drive motors, linkage mechanisms, pneumatic components, etc. In the high temperature, high humidity, and high salt spray environment of the braising workshop, electrical components are prone to corrosion and failure, and seals are prone to aging and falling off. In addition, the built-in transmission structure has a large number of blind holes, gaps and interlayers, which are difficult to clean thoroughly, easily breed bacteria, pose food safety hazards, and do not meet the hygiene standards for food production.

[0006] 3. Inappropriate draining and shaking methods affect product quality: Existing draining methods mostly use natural drainage, which is inefficient and time-consuming; some use whole-basin shaking and shaking, where the material is repeatedly soaked in the dripping brine, which can easily lead to an overly salty taste and skin damage. At the same time, the energy of shaking is dispersed, and it is impossible to specifically remove the liquid adhering to the bottom, resulting in limited draining effect.

[0007] 4. The processes are fragmented and have a low degree of continuity: The processes of braising, draining, conveying and unloading are mostly connected by independent equipment. Manual labor is required to complete operations such as turning baskets and placing trays. This results in high labor costs, a high risk of secondary pollution, and waiting bottlenecks in process connection, making it difficult to achieve truly continuous large-scale production.

[0008] 5. Rigid unloading method leads to high product breakage rate: Existing tipping unloading methods mostly use rigid tipping plates, which makes materials susceptible to impact, collision, and scattering. This is especially true for tender products such as braised tofu, skinless poultry, and braised eggs, where the surface breakage rate is high, affecting product appearance and yield.

[0009] Therefore, developing an automated conveying production line for braised products that is simple and reliable in structure, leak-free throughout the entire process, has no unsanitary corners, and integrates braising and unloading is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0010] The purpose of this invention is to provide an automated conveying production line for braised products in order to solve the above problems.

[0011] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0012] An automated conveying production line for braised products includes a first conveying guide rail and a suspended conveying assembly. The first conveying guide rail is composed of two parallel guide rails, and a second conveying guide rail is arranged between the two parallel guide rails. A sliding suspension assembly is slidably connected to both the first and second conveying guide rails. A conveying chain is arranged on the outer side of both the first and second conveying guide rails, and the conveying chain drives the corresponding sliding suspension assembly to move.

[0013] The suspended conveying assembly includes a mesh frame, a hanging rod, a bottom support plate, and an elastic skirt. The mesh frame is suspended below the first conveying guide rail by a sliding assembly, and the hanging rod is suspended below the second conveying guide rail by a sliding assembly. An elastic support plate is provided on the top of the bottom support plate and is fixedly installed at the bottom end of the hanging rod. The elastic skirt is provided around the bottom support plate and can swing up and down as the bottom support plate is raised and lowered.

[0014] Furthermore, the second conveying guide rail is divided into the following sections along the conveying direction: brine discharge section, liquid shaking section, rapid material collection section, anti-drip conveying section, unloading switching section, and unloading section.

[0015] The discharge section of the braising liquid is flush with the corresponding part of the first conveyor rail, the bottom support plate supports the bottom of the mesh frame, and the whole is detached from the braising liquid;

[0016] The liquid-shaking section is designed in a wave pattern, so that the bottom support plate shakes at a small amplitude and high frequency without leakage.

[0017] The fast material-collecting section is tilted at an angle of 80-85°, which allows the bottom support plate to quickly separate from the wire mesh frame, and the elastic skirt flips up, forming a cone shape with the bottom support plate and the elastic skirt facing upwards.

[0018] The anti-drip conveying section ensures that the bottom support plate and the elastic skirt maintain a stable upward-facing cone shape for conveying;

[0019] The unloading switching section causes the bottom support plate to rise, the elastic skirt to fold down, and there is an unloading space between the bottom support plate and the wire mesh frame. The bottom support plate and the elastic skirt form a cone shape with the opening facing downward.

[0020] The unloading section ensures that the bottom support plate and the elastic skirt maintain a stable cone shape with the opening facing downwards for conveying.

[0021] Furthermore, the tilt angle of the unloading switching section is smaller than that of the rapid material collection section, and the unloading section is lower than the brine discharge section.

[0022] Furthermore, a number of chain guide wheels are provided on the outer side of the second conveying guide rail, and the chain guide wheels ensure that the corresponding conveying chain is consistent with the shape of the second conveying guide rail.

[0023] Furthermore, each of the four corners of the mesh frame is provided with a guide foot, the bottom end of the guide foot is inclined outward, and the bottom end of the guide foot is hinged to a swing guide. Each of the four corners of the bottom support plate is hinged to a swing rod, which is slidably connected in the swing guide. The four sides of the elastic skirt are respectively installed on the corresponding swing rod.

[0024] Furthermore, the upper surface of the base plate is recessed.

[0025] Furthermore, each of the four sides of the elastic skirt is provided with an insert, and the inside of the swing arm is provided with an installation slot. The insert is inserted into the installation slot, and the bottom end of the swing arm is threaded with a limit nut, which can block the entrance of the installation slot.

[0026] Furthermore, a pressure frame is provided on the inner side of the elastic skirt, and the pressure frame is used to fix the elastic skirt to the bottom of the base plate by bolts.

[0027] Furthermore, the cross-sections of both the first and second conveying guide rails are arranged in an inverted T shape.

[0028] Furthermore, the sling assembly consists of a Y-shaped bracket and two sets of guide wheels.

[0029] The beneficial effects of this invention are as follows:

[0030] 1. This invention adopts a layered and independent drive system for the first and second conveying guide rails. The mesh frame and the bottom support plate are driven by the sliding components on the corresponding guide rails. All working condition switching is automatically triggered by the change in the trajectory height of the second conveying guide rail. The suspended basket body has no power or electrical components and operates purely mechanically without power, completely avoiding electrical failure and sealing failure problems in high temperature, high humidity, and high salt spray environments, and greatly improving the stability of operation.

[0031] 2. This invention, through the setting of elastic skirt, can isolate the brine on the bottom and top surfaces, and can quickly shake off the brine on the bottom surface. Then, in the tipping state, the elastic skirt flips up to form an upward-facing conical hopper with an opening area larger than the bottom area of ​​the mesh frame. It can completely catch the brine, oil, and food residue dripping from the mesh frame. No droplets fall to the ground during the transportation process, replacing the traditional solution of arranging liquid receiving tanks throughout the entire line. It fundamentally solves the industry pain points of oil and soup accumulation on the floor of the braising workshop, breeding mosquitoes, and serious odors, and avoids the secondary hygiene problem of difficult-to-clean liquid receiving tanks.

[0032] 3. In the rapid material-catching stage of this invention, the hysteresis effect formed by the rotational inertia of the swing arm and the frictional resistance of the guide groove automatically realizes the action sequence of "first stabilizing the material on the concave surface, then catching it with the flipped edge": When the swing arm descends rapidly, the elastic support plate first fits against the concave surface of the bottom support plate, forming a buffer concave surface to receive the material falling from the mesh frame, avoiding the material bouncing and impact; then the swing arm slowly swings upward, causing the elastic skirt to gradually gather into a catching shape. The entire process is flexible and there is no rigid impact, which is especially suitable for soft and fragile products such as braised eggs, braised tofu, and skinless poultry, greatly reducing the breakage rate during transportation.

[0033] 4. After unloading, the contact surfaces of the elastic skirt, mesh frame, and base plate are completely exposed, facilitating cleaning during continuous operation. The elastic skirt uses a quick-release structure with insert strips and limit nuts for sealing, which, together with the pressure frame, secures it to the base plate. It can be quickly disassembled and replaced without special tools. After the equipment is shut down, it can be soaked in cleaning agent for disinfection to thoroughly remove oil film and protein residue, leaving no cleaning dead corners and fully meeting the audit requirements of food safety production standards.

Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0043] Example 1, as Figures 1-7 As shown, an automated conveying production line for braised products includes a first conveying guide rail 1 and a suspended conveying assembly. The first conveying guide rail 1 is composed of two parallel guide rails, and a second conveying guide rail 2 is arranged between the two parallel guide rails. A sliding suspension assembly 5 is slidably connected to both the first conveying guide rail 1 and the second conveying guide rail 2. A conveying chain 3 is arranged on the outer side of both the first conveying guide rail 1 and the second conveying guide rail 2, and the conveying chain 3 drives the corresponding sliding suspension assembly 5 to move.

[0044] The suspended conveyor assembly includes a wire mesh frame 6, a suspension rod 7, a bottom support plate 8, and an elastic skirt 9. The wire mesh frame 6 is suspended below the first conveyor guide rail 1 by a sliding suspension assembly 5. The suspension rod 7 is suspended below the second conveyor guide rail 2 by a sliding suspension assembly 5. An elastic support plate 81 is provided on the top of the bottom support plate 8. The elastic support plate 81 is fixedly installed at the bottom end of the suspension rod 7. The elastic skirt 9 is provided around the bottom support plate 8. The elastic skirt 9 can swing up and down as the bottom support plate 8 rises and falls.

[0045] Workflow:

[0046] Braised food: The conveyor chain 3 provides the conveying drive. The mesh frame 6 and the bottom support plate 8 are conveyed together. The mesh frame 6 and the bottom support plate 8 are integrated and the braised products are stored inside. When the food is conveyed to the braising station, the corresponding parts on the first conveyor rail 1 and the second conveyor rail 2 are lower than the normal conveying height. The mesh frame 6 and the bottom support plate 8 descend together into the braising pot.

[0047] Shaking the liquid: After braising, the conveyor chain 3 provides the conveying drive, and the mesh frame 6 and the bottom support plate 8 move together to the normal height position on the first conveyor guide rail 1 and the second conveyor guide rail 2. At this time, the mesh frame 6 and the bottom support plate 8 are still above the braising pot. By controlling (this embodiment does not limit the specific control method) the bottom support plate 8 and the elastic skirt 9 to shake up and down with small amplitude and high frequency, the braising liquid on the bottom surface is quickly shaken off. At this time, the elastic skirt 9 is a cone with the opening facing down. Under the guidance of the inclined surface on the upper surface, the braising products on the upper part and the braising liquid on the mesh frame 6 will not affect the bottom surface. Therefore, when only the bottom surface is shaken, the efficiency is high. Shaking can also be performed during the braising process to improve the braising efficiency.

[0048] Tipping bucket: The elastic skirt 9 flips up into an upward-facing cone shape, and the opening area is larger than the bottom area of ​​the mesh frame 6. When combined with the bottom plate 8, it can completely catch the braised products and juices, keeping the bottom surface clean and drip-free, while the top receives the braised products and juices.

[0049] Unloading: Keeping the bucket in the tipping state, it can be transported to the unloading station over a long distance. Then, the elastic skirt 9 is flipped down, and the braised products are automatically slid to the unloading station under the guidance of the elastic tray 81 and the elastic skirt 9, achieving fast and efficient unloading. After unloading, it is kept in the state and transported to the cleaning station. After cleaning and drying, it can be recycled again.

[0050] The production line of this invention has a high degree of integration, zero leakage throughout the process, no dirt accumulation on the ground, and no droplets falling to the ground during the transportation process, thus fundamentally solving the industry pain points of oil and soup accumulation on the floor of the braising workshop, mosquito breeding, and strong odor.

[0051] The entire production line is elevated, eliminating unsanitary areas such as conveyor frames and transmission components on the ground. Daily maintenance only requires floor washing. The entire process is automated, eliminating the need for manual handling of materials for basket transfer and tray placement, reducing the risk of secondary contamination from personnel, and allowing direct passage through the clean packaging area.

[0052] Example 2, based on the above examples, further includes the second conveying guide rail 2 being divided into a brine discharge section 21, a liquid shaking section 22, a rapid material collection section 23, an anti-drip conveying section 24, a material unloading switching section 25, and a material unloading section 26 along the conveying direction.

[0053] The 21 section for discharging the brine is flush with the corresponding part of the first conveying guide rail 1, the bottom support plate 8 supports the bottom of the mesh frame 6, and the whole is detached from the brine;

[0054] The shaking section 22 is designed in a wave pattern, so that the bottom support plate 8 can shake at a small amplitude and high frequency without leakage.

[0055] The fast material-collecting section 23 is inclined at an angle of 80-85°, which allows the bottom support plate 8 to quickly separate from the wire mesh frame 6, and the elastic skirt 9 flips up, forming a cone shape with the bottom support plate 8 and the elastic skirt 9 facing upward.

[0056] The anti-drip conveying section 24 ensures that the bottom support plate 8 and the elastic skirt 9 are stably kept in an upward-facing cone shape for conveying.

[0057] The unloading switching section 25 causes the bottom support plate 8 to rise and the elastic skirt 9 to fall down. There is an unloading space between the bottom support plate 8 and the wire mesh frame 6. The bottom support plate 8 and the elastic skirt 9 form a cone shape with the opening facing downward.

[0058] The unloading section 26 ensures that the bottom support plate 8 and the elastic skirt 9 maintain a stable cone shape with the opening facing downwards for conveying.

[0059] The tilt angle of the unloading switching section 25 is less than that of the fast material scooping section 23, and the unloading section 26 is lower than the braising discharge section 21.

[0060] Several chain guide wheels 4 are provided on the outer side of the second conveying guide rail 2, and the chain guide wheels 4 make the corresponding conveying chain 3 keep the shape consistent with the second conveying guide rail 2.

[0061] The four corners of the frame 6 are provided with guide feet 61, the bottom of the guide feet 61 is inclined outward, and the bottom of the guide feet 61 is hinged to a swing guide 62. The four corners of the base plate 8 are hinged to swing rods 82, which are slidably connected in the swing guide 62. The four sides of the elastic skirt 9 are respectively installed on the corresponding swing rods 82.

[0062] The upper surface of the base plate 8 is recessed.

[0063] This embodiment has a simple structure. By simply changing the shape of the second conveying guide rail 2, the control of the bottom support plate 8 and the elastic skirt 9 can be achieved. There is no need to set up a complex structure on the mesh frame 6. The structure is simple, and it is not easy to have sanitary dead corners, which greatly reduces the amount of liquid hanging.

[0064] The specific workflow is as follows:

[0065] Braising: The conveyor chain 3 provides the conveying drive. The mesh frame 6 and the bottom support plate 8 are conveyed together. The mesh frame 6 and the bottom support plate 8 are integrated and store the braised products inside. When the products are conveyed to the braising station, the corresponding parts of the first conveyor guide rail 1 and the second conveyor guide rail 2 are lower than the normal conveying height (that is, the braising discharge section 21). The mesh frame 6 and the bottom support plate 8 descend together into the braising pot. The location of this process is not shown in the attached figure. It is a conventional guide lifting or lowering design. The height of the first conveyor guide rail 1 and the second conveyor guide rail 2 should be kept consistent.

[0066] Shaking the liquid: After the braising is completed, the conveyor chain 3 provides the conveying drive, and the mesh frame 6 and the bottom support plate 8 move together to the braising discharge section 21. At this time, the mesh frame 6 and the bottom support plate 8 are still above the braising pot. Then they move to the shaking section 22. Under the guidance of the wave structure, the hanging rod 7 moves up and down. When the hanging rod 7 descends, the bottom support plate 8 descends synchronously under the weight. When the hanging rod 7 rises, it drives the bottom support plate 8 to rise through the elastic support plate 8. When the bottom support plate 8 rises and falls, it drives the swing rod 82 to rise and fall. The tilting and sliding of the swing rod 82 not only slides relative to the swing guide 62, but also drives the swing guide 62 to swing together. The swing rod 82 drives the elastic skirt 9 to swing. Through the small amplitude and high frequency of up and down shaking of the elastic support plate 8 and the elastic skirt 9, the braising liquid on the bottom surface is quickly shaken off. At this time, the elastic skirt 9 is a cone with the opening facing down. Under the guidance of the inclined surface on the upper surface, the braising products on the upper part and the braising liquid on the mesh frame 6 will not affect the bottom surface. Therefore, when only the bottom surface is shaken, the efficiency is high. The braising process can also be vibrated (simply set a wave shape in the braising section, and the conveyor chain 3 provides reciprocating drive) to improve the braising efficiency.

[0067] Tipping bucket: The conveyor chain 3 drives the sliding assembly 5 to move to the fast material collection section 23. Due to the steep slope of the fast material collection section 23, the boom 7 will descend a large distance quickly. At this time, the boom 7 descends quickly. Since the swing arm 82 needs to slide and swing at an angle, the lag effect formed by the rotational inertia of the swing arm 82 and the frictional resistance of the guide groove causes the boom 7 to first make the elastic bottom support plate 81 fit against the bottom support plate 8. Since the upper surface of the bottom support plate 8 is concave, the elastic bottom support plate 81 forms a concave surface to ensure that the braised products will not slide outward. Then the boom 7 drives the bottom support plate 8 to descend quickly. During this process, the swing arm 82 swings upward. When the bottom support plate 8 descends to the bottom, the swing arm 82 swings to an upward angle. The swing arm 82 makes the elastic skirt 9 turn up into an upward-facing cone shape, and the opening area is larger than the bottom area of ​​the mesh frame 6. It can completely catch the braised products and juice when it cooperates with the bottom support plate 8. The bottom surface is kept clean and does not drip, while the top receives the braised products and juice.

[0068] Unloading: Maintaining the tipping state, the product can be transported over a long distance to the unloading station via the anti-drip conveying section 24. Then, the conveyor chain 3 drives the sliding crane assembly 5 to move to the unloading switching section 25. The sliding crane assembly 5 drives the lifting rod 7 to rise. The lifting rod 7 first drives the bottom support plate 8 to rise via the elastic support plate 81, and then the elastic skirt 9 is tilted down via the swing rod 82. At this time, there is a sufficient unloading gap between the bottom support plate 8 and the bottom surface of the mesh frame 6. Under the guidance of the elastic support plate 81 and the elastic skirt 9, the braised products have a gentle slope and stable deformation, which will not shake the braised products off. Under the action of gravity, the braised products automatically slide down the slope of the elastic support plate 81 and the elastic skirt 9 to the unloading station. Through the short-distance conveying of the unloading section 26, the braised products are evenly placed on the storage container or the conveyor belt below, achieving fast, efficient and stable unloading. After unloading, the product is transported to the cleaning station in the same state. After cleaning and drying, it can be reused.

[0069] In the third embodiment, based on the above embodiments, it further includes that the four sides of the elastic skirt 9 are provided with inserts 91, the inside of the swing rod 82 is provided with an installation slot 83, the inserts 91 are inserted into the installation slot 83, and the bottom end of the swing rod 82 is threadedly connected to a limit nut 84, which can block the entrance of the installation slot 83.

[0070] The inner side of the elastic skirt 9 is provided with a pressure frame 92, and the pressure frame 92 fixes the elastic skirt 9 to the bottom of the base plate 8 by bolts.

[0071] The elastic skirt 9 can be quickly removed by unscrewing the limit nut 84 and removing the bolts on the pressure frame 92. The elastic skirt 9 is a quick-release modular structure that can be quickly disassembled and soaked for disinfection after the equipment is stopped, thoroughly removing oil film and protein residue, and fully meeting the audit requirements of food safety production standards.

[0072] The elastic skirt 9 is made of food-grade fluororubber (FKM / FPM), with only food-contact grade meeting food safety standards and exhibiting extremely high chemical stability. It can withstand temperatures above 200℃ for extended periods, and its resistance to oil, salt, and acid / alkali corrosion is far superior to silicone rubber. It is also resistant to swelling and degradation even after prolonged contact with high-temperature broths. The elastic support plate 81 is made of stainless steel, offering high load-bearing capacity, stable deformation, and a smooth, pollution-free surface.

[0073] Example 4, based on the above examples, further includes an inverted T-shaped cross-section for both the first conveying guide rail 1 and the second conveying guide rail 2. The sliding assembly 5 consists of a Y-shaped bracket and two sets of guide wheels.

[0074] The double guide wheel setup improves load-bearing capacity and makes conveying more stable. The inverted T-shaped guide rail design allows for connection of the suspension component in the middle, enabling it to be suspended and installed in the factory without affecting the movement of the guide wheels, making it easy to arrange.

[0075] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
