Description

Technical Field

[0001] The invention belongs to the technical field of food processing, and in particular relates to a steaming room without temperature difference suitable for low-temperature steaming. Background Art

[0002] As a specialized device that uses steam to heat, cook, or process items, the steam room's existence and development stem from the rigid demand for "steam processing" in various fields. In areas such as food processing and medicinal material preparation, low-temperature steaming technology is increasingly widely used due to its advantages in preserving the nutrients of ingredients and maintaining their color and taste to the greatest extent.

[0003] In this existing design, traditional steam rooms mostly use natural convection with top air supply. Under the action of gravity, steam easily creates a temperature gradient, with hotter at the top and colder at the bottom. This leads to uneven heating of different layers of food in the same steam room, which not only affects the consistency of finished product quality, but also may cause the upper layer to be overcooked and the lower layer to be undercooked, resulting in food waste. At the same time, the steam flow rate is regulated by manual valves or fixed-diameter pipes, which makes it difficult to accurately and dynamically control the steam flow according to the characteristics of the food (such as seafood, pastries, meat) and the steaming stage (heating, constant temperature, and heat preservation). As a result, some food may lose excessive moisture due to excessive steam volume, or may not be cooked thoroughly due to insufficient steam.

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] Example:

[0038] like Figures 1 to 7 As shown:

[0039] In combination with the above content: A steam room with no temperature difference suitable for low-temperature steaming, comprising a steam room cabinet 1, and a steam circulation system 2, a sealing mechanism 3 and a steam flow regulating mechanism 4 arranged on the surface of the steam room cabinet 1;

[0040] The steam circulation system 2 includes a fan 21 and a drive motor 23 installed on the top of the steam room cabinet 1. A pipe 22 is provided on the surface of the steam room cabinet 1. The two ends of the pipe 22 are fixedly connected to the steam room cabinet 1 and the fan 21 respectively, and the output shaft of the drive motor 23 is fixedly connected to the fan 21.

[0041] The sealing mechanism 3 includes a heat-insulating sealing door 31 provided on the surface of the steam room cabinet 1, and the heat-insulating sealing door 31 is rotatably connected to the steam room cabinet 1 via a hinge assembly 32. Three groups of fixed supports 33 are symmetrically and evenly fixedly connected to the surface of the steam room cabinet 1. The surfaces of the fixed supports 33 are rotatably connected to the surfaces of the rotating connecting rods 34. Three groups of clamping blocks 35 are evenly and fixedly connected to the surface of the heat-insulating sealing door 31.

[0042] The steam flow regulating mechanism 4 includes an air outlet pipe 41 and an installation box 42 fixed on the top of the steam room cabinet 1. A connecting piece 43 is provided between the air outlet pipe 41 and the installation box 42. The two ends of the connecting piece 43 are fixedly connected to the air outlet pipe 41 and the installation box 42 respectively. The inner surface of the connecting piece 43 is rotatably connected to a rotating shaft 44, and the rotating shaft 44 rotates on the surface of the air outlet pipe 41 and the connecting piece 43. The surface of the rotating shaft 44 is fixedly connected to a linkage paddle 45 that fits the inner surface of the air outlet pipe 41.

[0043] In this embodiment, the driving motor 23 rotates its output shaft to drive the impeller of the fan 21 to rotate, forming a negative pressure in the pipe 22, sucking the steam in the steam room cabinet 1 from the top of the cabinet into the fan 21, and the pressurized steam is transported to the bottom of the steam room cabinet 1 through the pipe 22, and is ejected from the outlet of the pipe 22 to form a vertical circulating airflow from bottom to top. Through such continuous circulation, the steam in the steam room cabinet 1 is evenly distributed, ensuring that the food everywhere can obtain uniform heat, realizing low-temperature steaming without temperature difference, and the heat-insulating sealed door 31 rotates around the side of the steam room cabinet 1 through the hinge assembly 32. When closing, the handle 37 is manually pulled to bring the heat-insulating sealed door 31 close to the steam room cabinet 1. At this time, the user operates one end of the rotating connecting rod 34 to rotate around the fixed support 33, and the other end clamps the block 35. The three groups of rotating connecting rods 34 cooperate with the block 35 to isolate The heat-sealed door 31 is pulled tightly toward the steaming room cabinet 1, so that the heat-insulating sealed door 31 fits tightly against the steaming room cabinet 1. The heat-insulating sealed door 31 is pressed against the steaming room cabinet 1 through the lever principle, thereby preventing steam from leaking from the door gap and ensuring the stability of the steam pressure and temperature in the steaming room. When the steaming room cabinet 1 is working, the linkage paddle 45 fixedly connected to the surface of the rotating shaft 44 fits with the inner surface of the air outlet pipe 41. As the rotating shaft 44 rotates, the linkage paddle 45 swings in the air outlet pipe 41, changing the cross-sectional area of ​​the channel formed between the linkage paddle 45 and the inner wall of the air outlet pipe 41. When the cross-sectional area of ​​the channel increases, the flow rate of steam through the air outlet pipe 41 increases. When the cross-sectional area of ​​the channel decreases, the flow rate of steam through the air outlet pipe 41 decreases, thereby realizing precise adjustment of the steam flow in the steaming room to adapt to the steam volume requirements of different ingredients and steaming processes.

[0044] Going further:

[0045] like Figure 4 and Figure 5 As shown:

[0046] In an optional embodiment, the surface of the mounting box 42 is rotatably connected to a threaded rod 46, and the end of the rotating shaft 44 away from the linkage paddle 45 is symmetrically fixedly connected to a linkage plate 47, and a slider 48 is arranged between the linkage plates 47. Both ends of the slider 48 are fixedly connected to a limiting column 49, and the surface of the linkage plate 47 is provided with a sliding groove 410 that cooperates with the limiting column 49.

[0047] In this embodiment: the threaded rod 46 is driven to rotate, and the slider 48 cooperates with the threaded rod 46 through the internal thread to convert the rotational motion into linear motion. The limiting columns 49 at both ends of the slider 48 slide along the slide groove 410 of the linkage plate 47, pushing the linkage plate 47 to rotate around the axis of the rotating shaft 44, thereby driving the linkage paddle 45 to swing. The matching design of the limiting column 49 and the slide groove 410 makes the transmission process smooth and avoids jamming or shaking during adjustment. The threaded rod 46 transmission accurately converts the rotational motion into linear motion, ensuring that the angle adjustment of the linkage paddle 45 is stable and accurate, and the self-locking characteristics of the threaded pair ensure that the adjusted position remains stable and is not affected by steam pressure fluctuations.

[0048] Going further:

[0049] like Figure 5 As shown:

[0050] In an optional embodiment, the surface of the limiting column 49 is fixedly connected to the limiting plate 411 .

[0051] In this embodiment, the limit plate 411 precisely constrains the axial displacement range of the slider 48 through physical contact with the linkage plate 47, forcing it to move between the two linkage plates 47, thereby preventing the slider 48 from deviating from the track and causing transmission failure.

[0052] Going further:

[0053] like Figures 3 to 5 As shown:

[0054] In an optional embodiment, a servo motor 412 is mounted on the surface of the mounting box 42 , and an output shaft of the servo motor 412 is fixedly connected to the threaded rod 46 .

[0055] In this embodiment: the servo motor 412 drives the threaded rod 46 to rotate through the output shaft, which can quickly adjust the steam flow rate and promptly respond to temperature changes during the steaming process. At the same time, it uses an electric drive to drive the linkage paddle 45 to adjust the steam flow rate, thereby achieving precise transmission control and ensuring the accuracy of steam flow regulation.

[0056] Going further:

[0057] like Figures 3 to 5 As shown:

[0058] In an optional embodiment, a motor mounting base 413 is fixedly connected to the top of the steam room cabinet 1, and a mounting groove matching the servo motor 412 is opened on the surface of the motor mounting base 413. The servo motor 412 is fixedly connected to the surface of the steam room cabinet 1 through the motor mounting base 413.

[0059] In this embodiment: the motor mounting base 413 is fixed to the top of the steam room cabinet 1, and its mounting groove is tightly matched with the outer shell of the servo motor 412 to ensure stable installation of the motor and good shock absorption and noise reduction effect. The firm fixation of the motor mounting base 413 reduces the vibration transmission during the operation of the servo motor 412, reduces the overall noise of the equipment, and avoids loosening or wear of components caused by vibration.

[0060] Going further:

[0061] like Figure 7 As shown:

[0062] In an optional embodiment, the surface of the block 35 is provided with an arc-shaped slot 36 that cooperates with the rotating connecting rod 34 , the surface of the heat-insulating sealing door 31 is fixedly connected with a handle 37 , and the surface of the block 35 is provided with a guide slope 38 .

[0063] In this embodiment: when closing the heat-insulating sealed door 31, the rotating connecting rod 34 rotates around the fixed support 33, and the side away from the fixed support 33 slides into the arc-shaped slot 36 along the guide slope 38 of the block 35. The guide slope 38 guides the rotating connecting rod 34 to slide on the surface of the block 35, reducing the difficulty of closing the door, making the closing process effortless and smooth, and not easily fatigued even if the door is opened and closed frequently, thereby improving the convenience of use for the operator. The handle 37 helps the user to accurately control the heat-insulating sealed door 31.

[0064] Going further:

[0065] like Figure 7 As shown:

[0066] In an optional embodiment, one end of the rotating connecting rod 34 away from the fixed support 33 is fixedly connected to a rubber sleeve 39 .

[0067] In this embodiment: a rubber sleeve 39 is installed at the end of the rotating connecting rod 34 away from the fixed support 33. During use, since the rubber sleeve 39 is made of high-temperature resistant material, it can isolate the high temperature conduction of the steam room, avoiding burns caused by direct contact with high-temperature metal parts when opening and closing the door, thereby improving operational safety. The texture design of the rubber surface increases friction to prevent hands from slipping. At the same time, its elastic material fits the palm of the hand, reducing fatigue caused by long-term operation and optimizing the human-computer interaction experience.

[0068] Going further:

[0069] like Figure 7 As shown:

[0070] In an optional embodiment, an annular sealing strip 310 is fixedly connected to one side of the heat-insulating sealed door 31 close to the steam room cabinet 1 .

[0071] In this embodiment: an annular sealing strip 310 is installed on the side of the heat-insulating sealed door 31 close to the cabinet body. When the door is closed, the annular sealing strip 310 is squeezed and deformed, filling the gap between the door and preventing steam leakage, thereby achieving efficient sealing and heat preservation. The annular structure achieves 360-degree all-round sealing, and cooperates with the mechanical locking force to greatly reduce steam leakage, maintain stable temperature and pressure in the steam room, and reduce energy consumption.

[0072] Going further:

[0073] like Figure 8 and Figure 9 As shown:

[0074] In an optional embodiment, a flexible variable-diameter bellows 24 is provided inside the pipe 22 .

[0075] In this embodiment: a flexible variable-diameter bellows 24 is set inside the pipe 22, and its expansion and contraction deformation is driven by air pressure to change the inner diameter of the pipe 22, adjust the local steam flow rate and flow, compensate for insufficient airflow in the corner area, and realize flexible adjustment of steam parameters. The flexible material automatically adapts to the expansion and contraction of the pipe 22 caused by temperature changes, avoids the rupture of the pipe 22 or leakage at the connection due to stress concentration, improves system reliability, and the inner wall of the flexible variable-diameter bellows 24 is smooth, which can reduce the steam flow resistance, reduce energy loss, and improve steam transmission efficiency.

[0076] like Figure 6 As shown:

[0077] In an optional embodiment, an electric control box 5 is fixedly connected to the side wall of the steam room cabinet 1 , an inspection door 51 is rotatably connected to the surface of the electric control box 5 , and a rotary handle 52 is installed on the surface of the inspection door 51 .

[0078] In this embodiment: the electric control box 5 is fixed to the side wall of the steam room cabinet 1, and integrates control components such as PLC and driver. The inspection door 51 is opened and closed by the eccentric cam structure of the rotating handle 52. When closed, the cam squeezes the door frame to form a seal, which is convenient and efficient. The rotating handle 52 can open the door quickly, and the electric control components can be inspected without tools, which shortens the troubleshooting and maintenance time and improves the equipment availability. The electric control box 5 is installed on the side wall of the steam room cabinet 1, does not occupy the internal space of the steam room, and is convenient for line connection and operation panel layout, making the overall structure of the equipment compact and the appearance neat.

[0079] It should be noted that: the frequency converter is integrated in the electrical control box 5, and the speed of the fan 21 is adjusted by changing the power supply frequency of the drive motor 23. The operator controls the start and stop of the drive motor 23 through the buttons on the panel of the electrical control box 5. The PLC controller in the electrical control box 5 sends a pulse signal to the driver of the servo motor 412 to control the rotation angle and speed of the motor. The operator can select different steaming modes through the touch screen or buttons of the electrical control box 5.

[0080] Working principle: The electric control box 5 is fixed on the side wall of the steaming cabinet 1, and the inside is integrated with frequency converters, PLC controllers and other elements. The electrical connection and signal debugging with the driving motor 23 and the servo motor 412 are completed through the cable. When the food needs to be steamed, open the heat-sealing door 31, use the handle 37 to exert force, make the heat-sealing door 31 rotate and open around the hinge assembly 32, place the food to be steamed on the steaming rack in the steaming cabinet 1, then close the heat-sealing door 31, operate the rotating link 34 to rotate around the fixed support 33, make one end of the rotating link 34 away from the fixed support 33 slide into the arc-shaped clamping groove 36 along the guide slope 38 of the clamping block 35, three groups of rotating links 34 cooperate with the clamping block 35, tightly press the heat-sealing door 31 on the steaming cabinet 1 through the lever principle, the annular sealing strip 310 is deformed under pressure, realizing sealing, using the lever principle to amplify the pulling force, combined with the elastic deformation of the annular sealing strip 310, realizing 360-degree omnibearing sealing, the steam leakage rate is extremely low, effectively maintaining the stability of the pressure and temperature in the steaming room, and the design of the guide slope 38 can be automatically clamped without precise alignment, reducing the operation difficulty and labor intensity.
