Description

Technical Field

[0001] This utility model relates to the field of pre-prepared food processing technology, and more specifically, it relates to a braised meat steaming device for pre-prepared food processing. Background Technology

[0002] Against the backdrop of the rapid development of the pre-cooked food industry, braised meat products, as an important category of pre-cooked food, have placed higher demands on the safety and efficiency of steaming and cooking equipment. Currently, most braised meat steaming and cooking equipment on the market adopts high-pressure processing technology to shorten processing time and improve product quality. However, these devices have obvious shortcomings in actual production. In particular, under high-pressure processing conditions, when the pressure inside the steaming and cooking container rises abnormally, existing equipment generally lacks a rapid and effective pressure relief mechanism. Traditional pressure relief methods often require manual intervention or complete shutdown, which not only affects production efficiency but may also lead to safety hazards due to delayed pressure relief. In addition, the pressure relief process is often accompanied by the instantaneous release of a large amount of steam, increasing the safety risks for operators, especially in high-temperature and high-pressure environments, which can easily cause accidents such as burns.

[0003] In an industry environment where food safety standards are becoming increasingly stringent, the precise control of the cooking process for braised meat directly affects the quality and safety of the final product. Existing cooking equipment pressure control systems generally suffer from difficulties in adjusting preset thresholds. Operators find it difficult to flexibly adjust pressure parameters according to the characteristics of different batches of raw materials or product requirements. The adjustment process usually requires professional technicians to use specific tools, which is complex and time-consuming, and cannot meet the needs of modern production lines for rapid switching of production formulas. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, this utility model provides a pre-cooked braised meat steaming device for food processing, so as to solve the technical problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a pre-prepared braised meat steaming device, comprising a steaming furnace, a top cover at the top of the steaming furnace, a pressure relief mechanism on the top cover, the pressure relief mechanism comprising a pressure relief sleeve and a pressure relief pipe, the pressure relief sleeve being fixed to the top of the top cover, the pressure relief pipe being disposed on the outer wall of the pressure relief sleeve, a sealing mechanism being disposed inside the pressure relief sleeve, the sealing mechanism comprising a bottom plate and a sealing plate, the bottom plate being fixed to the bottom end of the pressure relief sleeve, the sealing plate abutting against the top surface of the bottom plate, an adjusting mechanism being disposed inside the pressure relief sleeve, the adjusting mechanism comprising an adjusting sleeve and a screw, the adjusting sleeve rotating at the top of the pressure relief sleeve, the screw being fixed to the bottom surface of the adjusting sleeve and rotatably connected to the bottom plate.

[0008] The present invention is further configured such that a transmission sleeve is threadedly connected to the outer wall of the screw, and an adjustment plate is fixedly provided on the outer wall of the transmission sleeve. The rotational motion of the screw is converted into the linear motion of the transmission sleeve through the threaded connection structure, thereby realizing the precise pressure threshold adjustment function and improving the accuracy and stability of the adjustment.

[0009] The present invention is further configured such that a pressure spring is connected to the top of the sealing plate, and the top of the pressure spring is fixedly connected to the bottom surface of the adjusting plate. The pressure spring acts as an elastic element to connect the sealing plate and the adjusting plate, which not only provides the preset pressure required by the sealing plate, but also enables the sealing plate to automatically reset after the pressure is released, thus ensuring the reliability and automation of the pressure relief system.

[0010] The present invention is further configured such that a sealing groove is provided on the top surface of the base plate, and a sealing strip is fixedly provided on the bottom surface of the sealing plate. The sealing strip abuts against the sealing groove, and the precise fit between the sealing strip and the sealing groove forms an efficient sealing structure, which prevents steam leakage and improves the sealing effect. At the same time, it can separate in time when the pressure exceeds the threshold, ensuring the unobstructed pressure relief channel.

[0011] The present invention is further configured such that a guide strip is fixedly provided on the outer wall of the sealing plate, and a guide groove is provided on the inner wall of the pressure relief sleeve. Multiple sets of guide strips and guide grooves are provided and slidably connected. The slidable connection between the multiple sets of guide strips and guide grooves ensures that the sealing plate maintains stable linear motion during the up and down movement, prevents skewing or jamming, and improves the operational stability and service life of the pressure relief mechanism.

[0012] The present invention is further configured such that a limiting rod is fixedly provided on the inner wall of the pressure relief sleeve. The limiting rod is provided in multiple sets and is slidably connected to the adjusting plate. The sliding connection structure between the multiple sets of limiting rods and the adjusting plate restricts the rotation of the adjusting plate, ensuring that the adjusting plate can only move along the axial direction, preventing transmission failure, and ensuring the reliability and accuracy of the adjusting system.

[0013] The present invention is further provided with anti-slip strips on the outer wall of the adjusting sleeve. Multiple sets of anti-slip strips are distributed on the outer wall of the adjusting sleeve. The multiple sets of anti-slip strips increase the friction on the surface of the adjusting sleeve, enabling the operator to rotate the adjusting sleeve more easily and accurately. The threshold adjustment can be completed without professional tools, which improves the ease of operation of the equipment and the human-machine interaction experience.

[0014] The present invention is further configured such that the pressure relief pipe is provided in multiple sets respectively disposed on the outer wall of the pressure relief sleeve. The distributed design of multiple sets of pressure relief pipes increases the channel area for gas discharge, enabling the pressure to be released quickly and evenly, improving the pressure relief efficiency. At the same time, it disperses the exhaust airflow, reduces noise and impact during the pressure relief process, and improves the safety of the equipment and the comfort of the working environment.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a pre-processed braised meat steaming and cooking device, which has the following beneficial effects:

[0017] 1. By installing a top cover on the top of the cooking furnace and equipping it with a pressure relief mechanism including a pressure relief sleeve and a pressure relief pipe, combined with a sealing mechanism consisting of a bottom plate and a sealing plate, and an adjustment mechanism consisting of an adjustment sleeve and a screw, a complete automatic pressure relief system is formed. When the pressure inside the cooking furnace exceeds the preset threshold of the pressure spring, the air pressure will automatically push the sealing plate away from the bottom plate, forming an airflow channel, allowing the excessive pressure to be discharged in time through the pressure relief pipe. This solves the problem of inconvenient pressure relief when the pressure inside the cooking container is too high during high-pressure processing in the existing technology, greatly improving the safety and reliability of the equipment, and effectively preventing equipment damage or safety accidents caused by excessive pressure.

[0018] 2. The sealing structure includes a precise fit between the sealing groove and the sealing strip, as well as a sliding connection between the guide strip and the guide groove. This ensures the smooth movement of the sealing plate during the pressure-lifting and resetting process, avoiding skewing or jamming. At the same time, the distributed design of multiple pressure relief pipes improves the pressure relief efficiency, allowing the pressure to be released quickly and evenly. When the gas pressure inside the cooking furnace returns to normal, the pressure spring can automatically push the sealing plate to reset and restore the sealing state. This achieves fully automated control of the pressure relief process without manual intervention, ensuring the safety of operators and improving production efficiency.

[0019] 3. Through the anti-slip strip design on the outer wall of the adjusting sleeve, operators can easily rotate the adjusting sleeve without professional tools, driving the screw to rotate and engage with the transmission sleeve through a threaded connection. This allows for precise control of the compression degree of the pressure spring, enabling flexible adjustment of the pressure relief valve value. This solves the problem of inconvenient adjustment of preset valve values ​​in existing technologies, allowing the equipment to quickly adjust working parameters according to the characteristics of different batches of raw materials or product requirements. This meets the needs of modern production lines for precise control of process parameters, while also extending the service life of the equipment and reducing production costs.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0028] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0029] Please see Figures 1-5 A pre-prepared braised meat steaming device includes a steaming furnace 1, a top cover 2 at the top of the steaming furnace 1, a pressure relief mechanism on the top cover 2, the pressure relief mechanism including a pressure relief sleeve 3 and a pressure relief pipe 4, the pressure relief sleeve 3 being fixed to the top of the top cover 2, the pressure relief pipe 4 being disposed on the outer wall of the pressure relief sleeve 3, a sealing mechanism being disposed inside the pressure relief sleeve 3, the sealing mechanism including a bottom plate 5 and a sealing plate 6, the bottom plate 5 being fixed to the bottom end of the pressure relief sleeve 3, the sealing plate 6 abutting against the top surface of the bottom plate, and an adjustment mechanism being disposed inside the pressure relief sleeve 3, the adjustment mechanism including an adjustment sleeve 7 and a screw 8, the adjustment sleeve 7 rotating at the top of the pressure relief sleeve 3, and the screw 8 being fixed to the bottom surface of the adjustment sleeve 7 and rotatably connected to the bottom plate 5.

[0030] The screw 8 is threadedly connected to a transmission sleeve 9, and an adjustment plate 10 is fixedly mounted on the outer wall of the transmission sleeve 9. When the screw 8 rotates, the transmission sleeve 9 moves vertically through the threaded connection, thereby causing the adjustment plate 10 fixed on the outer wall of the transmission sleeve 9 to move up and down as well. This realizes the conversion of rotational motion to linear motion and provides a precise mechanical transmission mechanism for adjusting the preset threshold.

[0031] A compression spring 11 is connected to the top of the sealing plate 6. The top of the compression spring 11 is fixedly connected to the bottom surface of the adjusting plate 10. The compression spring 11 serves as an elastic element connecting the sealing plate 6 and the adjusting plate 10. When the position of the adjusting plate 10 changes, the compression degree of the compression spring 11 can be adjusted, thereby changing the magnitude of the elastic force acting on the sealing plate 6, thus achieving the adjustment of the preset threshold. At the same time, after depressurization, it can provide a reset force to return the sealing plate 6 to the sealing position.

[0032] A sealing groove 12 is provided on the top surface of the bottom plate 5, and a sealing strip 13 is fixedly provided on the bottom surface of the sealing plate 6. The sealing strip 13 abuts against the sealing groove 12, and the sealing strip 13 and the sealing groove 12 form a sealing fit, which completely seals the internal space of the cooking oven under normal conditions. When the internal pressure exceeds the set threshold, the pressure pushes the sealing plate 6 to move upward, causing the sealing strip 13 to disengage from the sealing groove 12, forming a pressure relief channel, and realizing the automatic pressure regulation function.

[0033] A guide strip 14 is fixedly provided on the outer wall of the sealing plate 6, and a guide groove 15 is provided on the inner wall of the pressure relief sleeve 3. Multiple sets of guide strips 14 and guide grooves 15 are provided and slidably connected. The guide strips 14 slide in the guide grooves 15 to ensure that the sealing plate 6 can only move in the vertical direction without deflection or rotation, thus ensuring the stability and accuracy of the movement of the sealing plate 6 and improving the reliability and service life of the pressure relief mechanism.

[0034] The inner wall of the pressure relief sleeve 3 is fixedly provided with a limiting rod 16. There are multiple sets of limiting rods 16, all of which are slidably connected to the adjusting plate 10. The limiting rods 16 provide a guide track for the movement of the adjusting plate 10, ensuring that the adjusting plate 10 can only move along the axial direction and will not rotate. At the same time, the design of multiple sets of limiting rods 16 increases the structural strength, prevents the adjusting plate 10 from deforming when subjected to force, and ensures the accuracy and stability of the adjusting system.

[0035] The outer wall of the adjusting sleeve 7 is provided with anti-slip strips 17. Multiple sets of anti-slip strips 17 are distributed on the outer wall of the adjusting sleeve 7. The anti-slip strips 17 increase the friction of the surface of the adjusting sleeve 7, making it easier for operators to grip and rotate the adjusting sleeve 7. The threshold adjustment operation can be completed without the use of professional tools, which improves the human-machine interaction and ease of operation of the equipment.

[0036] Multiple pressure relief pipes 4 are provided on the outer wall of the pressure relief sleeve 3. The multiple pressure relief pipes 4 increase the total cross-sectional area of ​​gas discharge. When the sealing plate 6 moves upward to form a pressure relief channel, the high-pressure gas in the cooking furnace can be discharged simultaneously through multiple pressure relief pipes 4, which improves the pressure relief speed and efficiency, while dispersing the airflow impact force and reducing noise and vibration during the pressure relief process.

[0037] In this embodiment, the top cover 2 is fixed to the top of the steamer 1 to heat the steamer 1 for pre-cooking. When the pressure inside the steamer 1 is too high and exceeds the preset threshold of the pressure spring 11, the air pressure pushes the sealing plate 6, causing the sealing strip 13 to disengage from the sealing groove 12. The sealing plate 6 disengages from the top surface of the bottom plate 5 and squeezes the pressure spring 11. At this time, an airflow channel is formed between the sealing plate 6 and the bottom plate 5. After the air pressure passes through the airflow channel, it is discharged through multiple sets of pressure relief pipes 4. When the air pressure inside the steamer 1 is restored, the pressure spring 11 resets and pushes the sealing plate 6 back to abut against the top surface of the bottom plate, so that the sealing strip 13 abuts against the sealing groove 12, restoring the sealing state.

[0038] More specifically, when it is necessary to adjust the preset threshold of the compression spring 11, the rotating adjustment sleeve 7 drives the screw 8 to rotate. The rotation of the screw 8 engages with the transmission sleeve 9 through a threaded connection, causing the transmission sleeve 9 to drive the adjustment plate 10 to slide along multiple sets of limit rods 16 and compress the compression spring 11, thereby increasing the preset threshold of the sealing plate 6. Conversely, the compression spring 11 extends and decreases the preset threshold of the sealing plate 6.

[0039] In summary, during the use or operation of the entire equipment: the top cover 2 is fixed to the top of the steamer 1 to heat the steamer 1 for pre-cooking. When the pressure inside the steamer 1 is too high and exceeds the preset threshold of the pressure spring 11, the air pressure pushes the sealing plate 6, causing the sealing strip 13 to disengage from the sealing groove 12. The sealing plate 6 disengages from the top surface of the bottom plate 5 and squeezes the pressure spring 11. At this time, an airflow channel is formed between the sealing plate 6 and the bottom plate 5. After the air pressure passes through the airflow channel, it is discharged through multiple sets of pressure relief pipes 4. When the air pressure inside the steamer 1 is restored, the pressure spring 11 resets and pushes the sealing plate 6 back to abut against the top surface of the bottom plate, so that the sealing strip 13 abuts against the sealing groove 12, restoring the sealing state.

[0040] When it is necessary to adjust the preset threshold of the compression spring 11, the rotating adjustment sleeve 7 drives the screw 8 to rotate. The rotation of the screw 8 engages with the transmission sleeve 9 through a threaded connection, causing the transmission sleeve 9 to drive the adjustment plate 10 to slide along multiple sets of limit rods 16 and compress the compression spring 11, thereby increasing the preset threshold of the sealing plate 6. Conversely, the compression spring 11 extends and decreases the preset threshold of the sealing plate 6.

These will not be elaborated on here. For all the fixed connections mentioned above, welding is the preferred option.

[0042] In all the solutions mentioned above, the operation of electrical components, unless otherwise specified, is controlled by a controller. Since the devices matched with the controllers are common devices, their control principles and wiring connections are existing, well-known, and mature technologies, and their specific circuit structures will not be described in detail here. The specific models and specifications of the electrical components involved in this solution need to be selected and determined according to the actual specifications of the device.
