Description

Technical Field

[0001] This utility model relates to the field of rice noodle steaming technology, and in particular to a steam alarm device for a rice noodle steaming machine. Background Technology

[0002] Rice noodles are a specialty snack in southern China, often simply called "fen" by people in Jiangxi province. Made from rice, rice noodles are strips or strands produced through soaking, steaming, and pressing processes. They are soft yet chewy, elastic, and don't become mushy when boiled or break easily when stir-fried. Served with various toppings or broths, they are delicious and flavorful, making them a favorite among many consumers.

[0003] Currently, in the process of steaming rice flour sheets using steaming machines, the transmission structure inside the steaming machine often uses a rigid connection to drive the steaming container, which has problems such as large transmission impact and high noise. In addition, steam leakage in the steam box will lead to heat loss and a humid environment. Furthermore, the positioning and resetting of the steaming container relies on manual operation or a single spring structure, which is prone to displacement deviation or jamming, affecting the continuous production process. Therefore, we have proposed a steam alarm device for rice flour sheet steaming machines to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings in the above-mentioned background technology and to propose a steam alarm device for rice flour steaming machines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A steam outlet mechanism is provided on the outer wall of the steam box.

[0010] The steam outlet mechanism includes a steam generator fixedly installed on the outer wall of the steam tank, and multiple steam pipes connected to the steam generator exhaust port are fixedly installed on the inner wall of the steam tank. Multiple steam outlet nozzles are opened at the top of the steam pipes.

[0011] Preferably, the two ends of the return spring are fixedly connected to the outer wall of the steaming powder box and the inner wall of the steaming powder groove, respectively.

[0012] Preferably, the distance between two adjacent powder dispensing rods in the vertical direction is the same.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-4 The steam alarm device for the rice flour steaming machine includes a steam box 1, multiple steaming powder boxes 2, and a steam alarm body 3 fixedly installed at the bottom of the steaming powder boxes 2. The bottom of the steam box 1 is provided with a steaming mechanism. The steaming mechanism includes a steam trough 4 opened at the bottom of the steam box 1. Multiple steaming troughs 5 are opened at the top of the steam trough 4. Multiple grouting ports 6 connected to the steaming troughs 5 are opened at the top of the steam box 1. Multiple powder dispensing rods 7 are fixedly installed on the inner side wall of the steam trough 4. Multiple limiting holes 8 are opened on the outer side wall of the steaming powder boxes 2. The outer side wall of the powder dispensing rod 7 and the inner side wall of the limiting hole 8 are slidably connected. A return spring 9 is slidably sleeved on the outer side wall of the powder dispensing rod 7. A servo motor 10 is fixedly installed at the top of the steam box 1. A rotating shaft 11 is fixedly installed on the output shaft of the servo motor 10. The outer side wall of the rotating shaft 11 and the side wall of the steaming powder boxes 2 are flexibly traction connected by an alloy bifurcated wire 12.

[0026] To further explain, the steam alarm body 3 is fixed to the bottom of the steaming powder box 2, which can monitor steam abnormalities (such as temperature and pressure exceeding limits) in real time during the steaming process, and realize rapid feedback of alarm signals through integrated design. The steam tank 4 is equipped with multiple steaming plate slots 5 and grouting ports 6, which can process multiple portions of rice noodle raw materials at the same time, improving production efficiency. The servo motor 10 drives the rotating shaft 11 to flexibly pull the steaming powder box 2 through the alloy bifurcated line 12. Utilizing the tensile strength and flexible buffer of the alloy bifurcated line 12, the steaming powder box 2 can be moved smoothly and opened and closed, avoiding raw material spillage or equipment wear caused by rigid collision.

[0027] like Figure 2 As shown, the two ends of the return spring 9 are fixedly connected to the outer wall of the steaming sheet box 2 and the inner wall of the steaming sheet groove 5, respectively.

[0028] To further explain, when the servo motor 10 drives the rotating shaft 11 to loosen the alloy bifurcation line 12, the spring force pushes the steaming powder box 2 to automatically return to its position, reducing manual operation and ensuring the positioning accuracy of the workstation.

[0029] like Figure 1 As shown, the distance between two adjacent powder dispensing rods 7 in the vertical direction is the same.

[0030] To further explain, this design ensures that the steaming powder box 2 is subjected to uniform force during the sliding process, avoiding tilting or jamming of the steaming powder box 2 due to uneven spacing, and improving the operational stability of the equipment.

[0031] like Figure 1 As shown, a horizontal plate 16 and two support plates 17 are fixedly installed on the top of the steam box 1. The bottom of the servo motor 10 is fixedly connected to the top of the horizontal plate 16, and the two ends of the rotating shaft 11 are respectively rotatably connected to the outer side wall between the two support plates 17.

[0032] To further explain, this design fixes the servo motor 10 to the top of the steam box 1, ensuring high coaxiality when the shaft 11 rotates, reducing transmission vibration and noise, and extending the service life of the servo motor 10 and the shaft 11.

[0033] like Figure 1 As shown, the two steaming powder boxes 2 are symmetrically arranged in the steaming plate slot 5.

[0034] To further explain, this design ensures balanced load on both sides of the steam tank 4, preventing equipment swaying caused by eccentric forces, while simultaneously completing the loading, steaming, and unloading processes, thus improving capacity utilization.

[0035] like Figure 1 and Figure 4As shown, a steam outlet mechanism is provided on the outer wall of the steam box 1; the steam outlet mechanism includes a steam generator 13 fixedly installed on the outer wall of the steam box 1, and multiple steam pipes 14 connected to the steam outlet of the steam generator 13 are fixedly installed on the inner wall of the steam tank 4, and multiple steam nozzles 15 are opened at the top of the steam pipes 14.

[0036] To further explain, the steam generator 13 injects steam into the steam tank 4 through the steam pipe 14 and the steam nozzle 15. The design of multiple steam nozzles 15 ensures uniform temperature in the steaming area and improves the quality of rice noodles.

[0037] like Figure 1 and Figure 3 As shown, a sealing mechanism is provided on the top of the steam box 1. The sealing mechanism includes multiple horizontal L-shaped plates 18 fixedly installed on the top of the steam box 1. Two adjacent horizontal L-shaped plates 18 are symmetrically arranged on both sides of the grouting port 6. The same sealing plate 19 covering the grouting port 6 is slidably connected to the inner side wall of the two opposite horizontal L-shaped plates 18. Multiple steam outlet holes 20 are opened on the top of the sealing plate 19.

[0038] To further explain, this design can prevent heat loss due to steam leakage during steaming. The steam outlet 20 is designed to allow a small amount of steam to overflow, avoiding excessive internal pressure, while maintaining a slightly positive pressure in the steaming environment to ensure the rice noodles are cooked. The sealing plate 19 is removable, making it easy to clean the rice noodle slurry remaining near the slurry inlet 6 and preventing clumping and blockage.

[0039] like Figure 1 As shown, a discharge funnel 21 connected to the steam tank 4 is fixedly installed at the bottom of the steam tank 1, and a discharge control valve 22 is fixedly installed at the bottom of the discharge funnel 21.

[0040] To further explain, the discharge funnel 21, combined with the discharge control valve 22, can adjust the unloading speed according to the production rhythm, avoiding excessive discharge at one time that could lead to rice noodle accumulation; the inclined design of the discharge funnel 21 promotes smooth material flow and reduces residue waste.

[0041] The functional principle of this utility model can be explained through the following operation methods:

[0042] 1. Pre-start equipment checks

[0043] Confirm that the steam box 1 and the steam powder box 2 are securely installed, the return spring 9 is not deformed or broken, the powder discharge rod 7 and the limit hole 8 slide smoothly, check that the water level in the steam generator 13 water tank is sufficient, the steam pipe 14 and the steam nozzle 15 are not blocked, and the sealing plate 19 slides flexibly in the horizontal L-shaped plate 18.

[0044] 2. Loading and sealing

[0045] Open sealing plate 19: The initial state of the device is as follows Figure 1 As shown, multiple return springs 9 hold the two opposing steaming powder boxes 2 together tightly. The sealing plate 19 slides along the horizontal L-shaped plate 18, exposing the grouting port 6, and the rice flour slurry is injected: the well-stirred rice flour slurry is poured into the steaming powder box 2 through the grouting port 6. Note that it should not exceed 80% of the total volume of the two steaming powder boxes 2 to avoid the slurry overflowing during steaming. The sealing plate 19 is then closed: the sealing plate 19 is reset to cover the grouting port 6, ensuring that the steam outlet 20 is aligned with the center of the steaming plate groove 5 to prevent steam leakage.

[0046] 3. Start the steam generator 13 and servo motor 10.

[0047] Turn on the steam generator 13: Connect the power supply, set the steam temperature (usually 95-100℃), and after the steam pressure reaches the set value (such as 0.2-0.3MPa), the steam is evenly sprayed into the steam tank 4 through the steam pipe 14 from the steam nozzle 15.

[0048] Start the servo motor 10: Set the motor rotation direction and speed (such as clockwise low speed rotation) through the operation panel. The servo motor 10 drives the rotating shaft 11 to rotate, and the alloy forked line 12 pulls the steam powder box 2 to slide along the powder discharge rod 7 towards the center of the steam tank 4.

[0049] Observe the state of the reset spring 9: At this time, the reset spring 9 is in the compressed state, and the steaming powder box 2 moves smoothly to the designated position of the steaming powder slot 5, ensuring that the limit hole 8 is completely aligned with the powder dispensing rod 7.

[0050] 4. Steaming process and alarm monitoring

[0051] Uniform steaming: Steam diffuses to the surroundings through the steam nozzle 15 and enters the steaming tray 5 through the steam outlet 20 of the sealing plate 19 to uniformly heat the rice flour slurry. The steaming time is set according to the thickness of the slurry (usually 8-15 minutes).

[0052] Real-time monitoring and alarm: The steam alarm body 3 continuously monitors the steam temperature and pressure at the bottom of the steam powder box 2. If the temperature exceeds the threshold (e.g., 110℃) or the pressure drops suddenly (e.g., below 0.1MPa), the steam alarm body 3 will immediately issue an audible and visual alarm, and the servo motor 10 will automatically stop.

[0053] 5. Completion of steaming and unloading

[0054] Stop steam and motor: After the steaming time is reached, first turn off the steam generator 13, then turn off the servo motor 10, the rotating shaft 11 stops rotating, and the alloy bifurcation line 12 loosens.

[0055] Steaming powder box 2 resets: The reset spring 9 pushes the steaming powder box 2 to slide along the powder dispensing rod 7 to the outside of the steam box 1, and automatically returns to the initial position (at this time, the limiting hole 8 is close to the edge of the steam tank 4).

[0056] Opening the sealing plate 19 and discharging: Slide to open the sealing plate 19, and adjust the unloading speed through the discharge control valve 22 at the bottom of the discharge funnel 21. The steamed rice noodle sheets are discharged from the discharge funnel 21 and fall into the receiving container.

[0057] Clean residual slurry: Use a soft brush to clean the residual slurry on the inner wall of the steaming powder box 2 and near the slurry inlet 6 to prevent clumping and affecting the next use.

[0058] 6. Equipment cleaning and maintenance

[0059] Remove sealing plate 19: Loosen the fixing bolts on the horizontal L-shaped plate 18, remove sealing plate 19, rinse the steam vent 20 and plate surface with warm water to remove slurry residue.

[0060] Check the steam pipes: Regularly blow the steam pipe 14 and steam nozzle 15 with compressed air to prevent rice noodle particles from accumulating and clogging.

[0061] Lubricate the transmission components: Apply grease to the bearings of the rotating shaft 11 and the support plate 17 to ensure smooth rotation of the servo motor 10; check the connection points of the alloy branch line 12, and tighten them again if they are loose.

[0062] Calibrate the alarm: Calibrate the steam alarm body 3 monthly with a standard temperature / pressure sensor to ensure accurate monitoring data.

[0063] Precautions

[0064] During the steaming process, it is strictly forbidden to touch the surface of the steam chamber 1 to prevent burns. When dealing with alarm faults, the steam and power supply must be cut off first, and maintenance should be carried out after the equipment has completely cooled down. If the equipment is not used for a long time, the residual water in the water tank of the steam generator 13 must be drained to prevent scale growth.

[0065] By following the above steps, automated control of rice noodle steaming, ensuring steam uniformity, and rapid response to abnormal operating conditions can be achieved, significantly improving production efficiency and product quality.

[0066] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
