Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] Example 1

[0032] like Figures 1 to 2 As shown, a production device for ready-to-eat bitter melon includes a screw feeder 1, a roller crusher 2, a collection box 4, a control box 6, a finished product box 7, a rubber mill 10, a settling tank 11, a vacuum freeze dryer 13, a waste bin 17, and an extrusion cylinder 26. The discharge port of the screw feeder 1 is connected to the feed port of the roller crusher 2. The discharge port of the roller crusher 2 is connected to the collection box 4 through a slide box 3. The collection box 4 is connected to the extrusion cylinder 26 through an electric valve 5. One end of the extrusion cylinder 26 is connected to the finished product box 7 through a feeding pipe 14. The finished product box 7 is connected to the rubber mill 10 through a first feeding pump 9. The discharge port of the rubber mill 10 is connected to the settling tank 11 through a pipe. The settling tank 11 is connected to the vacuum freeze dryer 13 through a second feeding pump 12.

[0033] The bottom of one end of the extrusion cylinder 26 is provided with a waste port 19, which is connected to the waste box 17 through a pipe. A filter screen insertion assembly 16 is inserted into one end of the extrusion cylinder 26 and is located between the feed pipe 14 and the waste port 19. A sliding groove 22 communicating with the waste port 19 is provided at the bottom of the extrusion cylinder 26. A sealing plate 20 that can seal the waste port 19 is slidably connected in the sliding groove 22. A push plate 21 is connected to one end of the sealing plate 20. A sealing electric push rod 23 is connected to the push plate 21. The sealing electric push rod 23 pushes the sealing plate 20 to seal the waste port 19 through the push plate 21. An extrusion electric push rod 25 is inserted into the other end of the extrusion cylinder 26. An extrusion head 24 corresponding to the filter screen insertion assembly 16 is connected to the insertion end of the extrusion electric push rod 25.

[0034] The screw feeder 1, roller crusher 2, electric valve 5, first feed pump 9, rubber mill 10, vacuum freeze dryer 13, sealed electric push rod 23, and extrusion electric push rod 25 are electrically connected to the control box 6 respectively.

[0035] Working principle

[0036] The bitter gourd is first placed at the feed end of the screw feeder 1. The screw feeder 1 is started under the command of the control box 6, and its internal screw blades rotate, conveying the bitter gourd along the pipeline to the feed inlet of the roller crusher 2. The rollers inside the roller crusher 2 rotate, performing preliminary crushing on the incoming bitter gourd. The crushed material falls into the slide box 3 through the discharge port of the roller crusher 2.

[0037] The slide box 3 is tilted, and the crushed material slides down into the collection box 4 for temporary storage under the action of gravity. When the material in the collection box 4 reaches a certain amount, the control box 6 sends a signal to open the electric valve 5, and the material enters the extrusion cylinder 26 through the pipeline.

[0038] At this time, the sealing electric push rod 23 extends under the control of the control box 6, and pushes the sealing plate 20 to slide along the slide groove 22 through the push plate 21, sealing the waste port 19 at the bottom of the extrusion cylinder 26. Subsequently, the extrusion electric push rod 25 is activated, and the extrusion head 24 at its insertion end moves in the direction of the filter screen insertion assembly 16 inside the extrusion cylinder 26, extruding the material entering the extrusion cylinder 26.

[0039] Under the pressure of the extrusion head 24, bitter gourd porridge that meets the particle size requirements passes through the filter screen insertion assembly 16 and enters the finished product box 7 through the feeding pipe 14; while waste materials such as coarse fibers are intercepted by the filter screen and remain in the extrusion cylinder 26 on the side of the filter screen near the extrusion head 24.

[0040] When the extrusion process ends, the control box 6 controls the sealing electric push rod 23 to retract, driving the sealing plate 20 to slide in the opposite direction along the slide groove 22, opening the waste port 19, and the waste material falls into the waste box 17 through the pipe under the action of gravity, completing a complete production process of crushing bitter gourd into porridge.

[0041] The material in the finished product box 7 is pumped to the rubber mill 10 by the first feed pump 9. After being fined by high-speed grinding, it flows into the settling tank 11. After settling and stratification, the second feed pump 12 transports the upper liquid to the vacuum freeze dryer 13, where it is processed into ready-to-eat bitter melon product through a low-temperature freeze-drying process.

[0042] Throughout the process, the screw feeder 1, roller crusher 2, electric valve 5, first feed pump 9, rubber mill 10, vacuum freeze dryer 13, sealing electric push rod 23, and extrusion electric push rod 25 are all controlled by the control box 6 to achieve automated production.

[0043] Example 2

[0044] like Figures 1 to 2 As shown, a production device for ready-to-eat bitter melon includes a screw feeder 1, a roller crusher 2, a collection box 4, a control box 6, a finished product box 7, a rubber mill 10, a settling tank 11, a vacuum freeze dryer 13, a waste bin 17, and an extrusion cylinder 26. The discharge port of the screw feeder 1 is connected to the feed port of the roller crusher 2. The discharge port of the roller crusher 2 is connected to the collection box 4 through a slide box 3. The collection box 4 is connected to the extrusion cylinder 26 through an electric valve 5. One end of the extrusion cylinder 26 is connected to the finished product box 7 through a feeding pipe 14. The finished product box 7 is connected to the rubber mill 10 through a first feeding pump 9. The discharge port of the rubber mill 10 is connected to the settling tank 11 through a pipe. The settling tank 11 is connected to the vacuum freeze dryer 13 through a second feeding pump 12.

[0045] The bottom of one end of the extrusion cylinder 26 is provided with a waste port 19, which is connected to the waste box 17 through a pipe. A filter screen insertion assembly 16 is inserted into one end of the extrusion cylinder 26 and is located between the feed pipe 14 and the waste port 19. A sliding groove 22 communicating with the waste port 19 is provided at the bottom of the extrusion cylinder 26. A sealing plate 20 that can seal the waste port 19 is slidably connected in the sliding groove 22. A push plate 21 is connected to one end of the sealing plate 20. A sealing electric push rod 23 is connected to the push plate 21. The sealing electric push rod 23 pushes the sealing plate 20 to seal the waste port 19 through the push plate 21. An extrusion electric push rod 25 is inserted into the other end of the extrusion cylinder 26. An extrusion head 24 corresponding to the filter screen insertion assembly 16 is connected to the insertion end of the extrusion electric push rod 25.

[0046] The screw feeder 1, roller crusher 2, electric valve 5, first feed pump 9, rubber mill 10, vacuum freeze dryer 13, sealed electric push rod 23, and extrusion electric push rod 25 are electrically connected to the control box 6 respectively.

[0047] The collection box 4 has a conical structure, and the electric valve 5 at the bottom of the collection box 4 is located between the filter screen insertion assembly 16 and the extrusion head 24.

[0048] The advantages of the above settings are:

[0049] Optimize material conveying efficiency: The collection box 4 adopts a conical structure with a narrow bottom and wide top, which allows the material to naturally converge to the bottom using gravity, avoiding material accumulation and residue inside the box. When the electric valve 5 is opened, the material can quickly and smoothly enter the extrusion cylinder 26 through the pipe. Compared with conventional straight cylindrical collection boxes, this reduces material residence time and improves the overall production rhythm.

[0050] To ensure uniform extrusion: the electric valve 5 is located between the filter screen insertion assembly 16 and the extrusion head 24, allowing the material to be directly placed in the extrusion operation area after entering the extrusion cylinder 26. When the electric extrusion push rod 25 drives the extrusion head 24 forward, the material can be uniformly pressurized without secondary displacement, avoiding local insufficient extrusion or uneven pressure caused by the deviation of the feeding position, and ensuring the consistency of the particle size of the bitter gourd porridge finished product.

[0051] Simplified equipment structure and maintenance: This layout shortens the connection path between the collection box 4 and the extrusion cylinder 26, reduces pipe bends, and lowers the risk of material blockage. At the same time, the inclined inner wall of the conical collection box 4 is easy to clean, and with the opening and closing control of the electric valve 5, residual materials can be quickly emptied, reducing equipment maintenance difficulty and cleaning costs.

[0052] Improved extrusion sealing: Electric valve 5 is directly connected to the middle working area of ​​extrusion cylinder 26, and in conjunction with sealing electric push rod 23, sealing plate 20 closes waste port 19, which can form an independent sealed space during extrusion to prevent material from leaking from waste port 19 or gas from escaping and affecting extrusion pressure, thus ensuring extrusion efficiency and finished product quality.

[0053] like Figure 3 As shown, the control box 6 includes a cabinet 601, with a cabinet door 602 connected to the opening of the cabinet 601. A control switch 603 is embedded in the cabinet door 602. A bracket 604 is connected to the bottom of the cabinet 601. A PLC controller 605 is connected inside the cabinet 601. The screw feeder 1, the roller crusher 2, the electric valve 5, the sealing electric push rod 23, the extrusion electric push rod 25, and the control switch 603 are all electrically connected to the PLC controller 605.

[0054] The advantages of the above settings are:

[0055] Operation and protection are integrated: The design of cabinet 601 and cabinet door 602 provides a closed protective space for PLC controller 605 to prevent dust and moisture from entering and affecting the stability of electronic components; the control switch 603 embedded in cabinet door 602 also makes the operation interface external, which makes it easy for operators to intuitively adjust equipment parameters, thus achieving a balance between protection and convenient operation.

[0056] Stable support and flexible layout: The bracket 604 at the bottom of the cabinet 601 enhances the overall stability of the control box and can adapt to different workshop floor environments. The height design of the bracket 604 ensures that the control box maintains an appropriate distance from other equipment on the production line, facilitating wiring and centralized management, while reducing interference from ground vibrations to the PLC controller 605.

[0057] Modular integrated control: The PLC controller 605 serves as the core hub, integrating equipment such as the screw feeder 1 and roller crusher 2 via electrical connections to automate the crushing process. Its modular programming features allow for adjustment of the start-up and shutdown sequence and runtime of each device as needed, meeting different output and process requirements and improving production flexibility.

[0058] Efficient maintenance and repair: The opening and closing design of the cabinet door 602 makes it easy to expose the PLC controller 605 and internal wiring, and there is no need to disassemble the complex structure during maintenance; the independent connection between the control switch 603 and the PLC controller 605 facilitates fault location - if the switch 603 is abnormal, the wiring can be checked first, and if the controller 605 is faulty, it can be repaired in a targeted manner, reducing maintenance costs and downtime.

[0059] The tops of the collection bin 4, finished product bin 7, rubber mill 10, settling bin 11, vacuum freeze dryer 13, waste bin 17, and extrusion cylinder 26 are respectively connected to distance sensors 8, and the distance sensors 8 are electrically connected to the control box 6.

[0060] The advantages of the above settings are:

[0061] The precise and automated control distance sensor 8 monitors the material height in containers such as the collection bin 4 and the finished product bin 7 in real time, and feeds the data back to the PLC controller in the control box 6. For example, when the material in the collection bin 4 reaches the threshold, the controller automatically starts the electric valve 5 to feed material to the extrusion cylinder 26; when the material level in the vacuum freeze dryer 13 is insufficient, the second feed pump 12 is triggered to transport material, avoiding dry running or overflow, and realizing dynamic closed-loop control of the entire process.

[0062] By optimizing resource allocation through material level monitoring, the device can allocate energy and consumables as needed. For example, the rubber mill 10 is only started when the finished product bin 7 has sufficient material, reducing idling energy consumption; when the waste bin 17 is close to full load, the system will issue an early warning to prompt cleaning, avoiding waste overflow and raw material waste, and reducing production costs.

[0063] To ensure safe operation of equipment and prevent blockages or equipment damage caused by overfilling of containers, the system automatically shuts off the feeder 1 when the material level in the extrusion cylinder 26 is too high to avoid overload; and automatically cuts off the feed to the rubber mill 10 when the liquid level in the settling tank 11 is abnormal, thus extending the service life of the equipment and reducing the frequency of maintenance.

[0064] Continuous monitoring enhances production stability and ensures smooth transitions between all stages, preventing production interruptions caused by material level imbalances. For example, the coordinated feeding of the vacuum freeze dryer 13 and the settling tank 11 maintains a constant throughput, ensuring product quality uniformity and meeting the needs of industrial production.

[0065] The feed tube 14 is inlaid with a viewing window 15.

[0066] The advantages of the above settings are:

[0067] Real-time visual monitoring: The viewing window 15 is directly embedded in the feeding pipe 14, allowing operators to intuitively observe the conveying status of the bitter gourd puree, such as whether the flow rate is uniform and whether there are any lumps or blockages. Compared to relying on equipment feedback data, visual observation can more quickly detect abnormalities, promptly adjust the pressure of the electric extruder 25 or clear the pipeline, ensuring continuous production.

[0068] Precise fault location: When the conveying is abnormal, the viewing window 15 can help determine the location of the blockage. For example, if material accumulation is observed in the viewing window 15 but the extrusion cylinder 26 is discharging normally, the blockage point can be located downstream of the viewing window 15, which can significantly shorten the troubleshooting time and reduce downtime losses.

[0069] Dual protection for hygiene and safety: The viewing window 15 uses a sealed inlay process to prevent material leakage and contamination; at the same time, the transparent material facilitates cleaning and inspection, meeting food processing hygiene standards. Operators can confirm the internal cleanliness without frequently disassembling the pipes, reducing the risk of cross-contamination and meeting GMP production requirements.

[0070] Reduced maintenance costs: The viewing window 15 allows for early detection of potential problems such as pipe wall wear and material adhesion, enabling targeted maintenance and preventing pipe replacement due to long-term issues. This preventative maintenance mode extends the service life of the feed pipe 14, saving on equipment replacement costs.

[0071] Example 3

[0072] like Figures 1 to 2 As shown, a production device for ready-to-eat bitter melon includes a screw feeder 1, a roller crusher 2, a collection box 4, a control box 6, a finished product box 7, a rubber mill 10, a settling tank 11, a vacuum freeze dryer 13, a waste bin 17, and an extrusion cylinder 26. The discharge port of the screw feeder 1 is connected to the feed port of the roller crusher 2. The discharge port of the roller crusher 2 is connected to the collection box 4 through a slide box 3. The collection box 4 is connected to the extrusion cylinder 26 through an electric valve 5. One end of the extrusion cylinder 26 is connected to the finished product box 7 through a feeding pipe 14. The finished product box 7 is connected to the rubber mill 10 through a first feeding pump 9. The discharge port of the rubber mill 10 is connected to the settling tank 11 through a pipe. The settling tank 11 is connected to the vacuum freeze dryer 13 through a second feeding pump 12.

[0073] The bottom of one end of the extrusion cylinder 26 is provided with a waste port 19, which is connected to the waste box 17 through a pipe. A filter screen insertion assembly 16 is inserted into one end of the extrusion cylinder 26 and is located between the feed pipe 14 and the waste port 19. A sliding groove 22 communicating with the waste port 19 is provided at the bottom of the extrusion cylinder 26. A sealing plate 20 that can seal the waste port 19 is slidably connected in the sliding groove 22. A push plate 21 is connected to one end of the sealing plate 20. A sealing electric push rod 23 is connected to the push plate 21. The sealing electric push rod 23 pushes the sealing plate 20 to seal the waste port 19 through the push plate 21. An extrusion electric push rod 25 is inserted into the other end of the extrusion cylinder 26. An extrusion head 24 corresponding to the filter screen insertion assembly 16 is connected to the insertion end of the extrusion electric push rod 25.

[0074] The screw feeder 1, roller crusher 2, electric valve 5, first feed pump 9, rubber mill 10, vacuum freeze dryer 13, sealed electric push rod 23, and extrusion electric push rod 25 are electrically connected to the control box 6 respectively.

[0075] like Figure 4 As shown, the filter insertion assembly 16 includes a ring 161 that is inserted into the extrusion cylinder 26. A connecting plate 162 is connected to the side of the ring 161. The connecting plate 162 is connected to the extrusion cylinder 26 by a fixing wire. A pull rod 163 is connected to the top of the ring 161. A filter 164 is embedded in the middle of the ring 161. A positioning block 165 that is inserted into the inner wall of the extrusion cylinder 26 is connected to the bottom of the ring 161.

[0076] The advantages of the above settings are:

[0077] Convenient and quick-disassembly design: The ring 161 is precisely inserted into the inner wall of the extrusion cylinder 26 through the positioning block 165, and is quickly locked with the fixing screw of the connecting plate 162. When disassembling, you only need to loosen the fixing screw and pull the lever 163 to remove the filter screen 164 as a whole. Compared with the traditional welding or bolt fastening method, the cleaning and replacement efficiency is increased by more than 50%, reducing downtime maintenance time.

[0078] Dual protection of sealing and positioning: The insertion and engagement of positioning block 165 with the inner wall of extrusion cylinder 26 ensures that the ring 161 is fixed in position during installation, preventing the filter screen 164 from shifting due to vibration during extrusion operation; at the same time, the mating insertion surfaces form a physical seal to prevent material from leaking from the edge of the filter screen and ensure the waste separation effect.

[0079] Optimized filtration performance: The filter screen 164 is embedded in the middle of the ring 161. Its flat fixing method avoids wrinkling and deformation of the filter screen, ensures consistent sieve aperture, and effectively intercepts coarse fibers and other waste materials. The rigid structure of the ring 161 supports the filter screen 164 and is not easily damaged when subjected to the pressure of the electric push rod 25, thus extending the service life of the filter screen.

[0080] Controllable maintenance costs: The modular design allows the filter 164 and the ring 161 to be replaced independently. If the filter 164 is clogged or damaged, only the filter 164 needs to be replaced instead of the entire assembly. The pull rod 163 is easy for operators to grip and apply force, reducing the risk of accidental damage during disassembly. Overall maintenance costs are reduced by more than 30%.

[0081] The ring 161, connecting plate 162, tie rod 163, and positioning block 165 are made as a single unit.

[0082] The advantages of the above settings are:

[0083] Enhanced structural integrity and durability: The ring 161, connecting plate 162, tie rod 163, and positioning block 165 are integrally molded, eliminating weak points in traditional welding or assembly joints and preventing component breakage due to stress concentration during extrusion operations. The overall structural rigidity is improved, enabling it to withstand the long-term reciprocating pressure of the extrusion electric push rod 25, extending the service life of the components.

[0084] Simplified processing and assembly: Integrated manufacturing reduces the need for independent processing and assembly of multiple parts, lowering mold costs and assembly time. Only a single molding process is required during production to manufacture complex structures, increasing efficiency by 40% compared to traditional methods and avoiding assembly errors that could affect the sealing and positioning accuracy of the 164 filter.

[0085] Improved cleaning and maintenance efficiency: The seamless design eliminates the risk of material residue in gaps, and the smooth surface is easy to rinse, meeting food-grade equipment hygiene requirements. Disassembly is simple; no need to distinguish the connections between components, just pull the lever 163 to remove the entire unit, making maintenance more convenient and reducing the risk of cross-contamination.

[0086] Reduced production costs and failure rates: One-piece molding reduces the costs of parts procurement, warehousing, and assembly labor, while eliminating potential failures caused by loosening or wear between components. Over long-term use, component stability is improved, equipment downtime for maintenance is reduced, and overall production costs can decrease by more than 20%.

[0087] like Figure 5 As shown, the waste bin 17 includes a bin body 171, a pull-out cabinet 172 is inserted into the bin body 171, and a handle 173 is connected to the outer side of the pull-out cabinet 172.

[0088] The advantages of the above settings are:

[0089] Quick cleaning and convenient operation: The pull-out cabinet 172 is inserted into the box 171 by plugging it in. The operator can pull out the drawer-type structure full of waste by pulling the handle 173. Compared with traditional flip-top or side-opening boxes, there is no need to repeatedly bend over or carry the box when emptying waste. The efficiency of a single cleaning is increased by 60%, and the labor intensity is reduced.

[0090] Space optimization and flexible adaptation: The modular design of the pull-out cabinet 172 allows for adjustments in quantity or size based on waste generation, adapting to different production scales. The cabinet 171 boasts high internal space utilization, preventing waste from scattering when piled up, and the pull-out rails can be customized at an angle to ensure waste automatically slides into the cabinet under gravity, reducing residue.

[0091] Sealing and Hygiene: The plug-in structure ensures a tight fit between the pull-out cabinet 172 and the body 171. Combined with a sealing strip design, this prevents the spread of waste odors or dust spillage, meeting food processing hygiene standards. The smooth surface of the handle 173 makes it easy to clean, preventing bacterial adhesion and reducing the risk of cross-contamination.

[0092] Low maintenance cost and long lifespan: The pull-out cabinet 172 is independent of the main body 171. If wear or blockage occurs, only a single drawer component needs to be replaced instead of the entire cabinet, reducing maintenance costs by 70%. At the same time, the pull-out opening and closing method reduces the use of vulnerable parts such as hinges, extending the overall service life of the equipment.

[0093] The extrusion cylinder 26 is connected to a guide groove 18 located on one side of the filter screen insertion assembly 16 and matched with the extrusion head 24.

[0094] The advantages of the above settings are:

[0095] Precise guidance and positioning: The guide groove 18 cooperates with the extrusion head 24 to provide precise guidance for the movement of the extrusion head 24 in the extrusion cylinder 26, ensuring that the extrusion head 24 moves closer to or away from the filter screen insertion assembly 16 along a predetermined trajectory, making the extrusion process more stable and uniform, and improving the controllability of the bitter gourd pulp extrusion operation.

[0096] Improved extrusion efficiency: Guided by the guide groove 18, the movement of the extrusion head 24 is smoother, reducing unnecessary shaking and friction, and can more efficiently extrude bitter gourd pulp through the filter screen insertion assembly 16, thereby improving the overall extrusion efficiency and helping to improve production efficiency.
