Description

Technical Field

[0001] This utility model relates to the field of steam cooking equipment technology, and more specifically, to a dual-steam structure for a steel belt rice noodle roll machine. Background Technology

[0002] Whether it's an automatic rice noodle roll machine or a conventional electric rice noodle roll steamer, both are electrified devices that use electric heating to quickly heat a preset water tank, generating high-temperature steam. This high-temperature steam is then used to steam and cook the rice noodle roll batter inside the steamer / steamer. Conventional electric rice noodle roll steamers use a rice noodle roll tray to hold the batter, which is manually pushed into the steamer for steaming. Therefore, the water tank steamer built into the rice noodle roll machine only needs to be connected to the steamer cavity through a suitable circuit to heat and cook the rice noodle roll batter in the tray.

[0003] To improve the efficiency of making rice noodle rolls, automatic rice noodle roll machines have been gradually designed and continuously improved. These machines can minimize the workload and concentration required of rice noodle roll makers. After setting appropriate processing parameters and pre-mixing the necessary ingredients such as rice batter, sesame oil, and fillings, the machine automatically and continuously processes the rice noodle rolls to the desired flavor. The rice noodle roll maker only needs to transfer the finished rice noodle rolls to a plate in the final step.

[0004] The steel belt automatic rice noodle roll machine is a continuous and efficient automated rice noodle roll making equipment. Its biggest structural feature is the use of a rotating steel belt to circulate in and out of the steamer. Before entering the steamer, the steel belt is filled with food. As the steel belt continues to move, the food is gradually fed into the steamer. Subsequent steel belts can continue to repeat the feeding process. The steel belt that has entered the steamer will be steamed as it moves until it leaves the steamer. It leaves from the steamer's outlet and is then loaded onto a tray. After unloading, the steel belt will circulate back to the steamer's entry direction, thus realizing the cycle of rice noodle roll making.

[0005] However, existing automatic rice noodle roll machines with steel belts often operate at temperatures exceeding 90 degrees Celsius inside the steamer, while the outside temperature is typically room temperature, rarely exceeding 30 degrees Celsius. This significant temperature difference causes the rice noodle batter to flow and leak as it's spread onto the steel belt due to its lower temperature, resulting in uneven thickness of the rice noodle sheets and affecting the texture. Furthermore, from a culinary perspective, preheating the steel belt requires either running it empty within the steamer or using other methods to heat it. For example, existing methods include adding heating rods to the rollers driving the steel belt for preheating and temperature maintenance, or filling the rollers with hot water. However, these additional structures are not optimal for power consumption and increase the machine's overall energy usage. Effectively utilizing the steamer's inherent characteristics for temperature control of the steel belt can effectively address these shortcomings. Utility Model Content

[0006] To address the technical deficiencies in the background technology, this utility model proposes a dual-steam structure for a steel belt rice noodle roll machine, which solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows:

[0007] A dual-steam structure for a steel belt rice noodle roll machine includes a steam oven and a steam chamber connected to the steam oven via a steam passage. The steam chamber has a steam chamber inlet and a steam chamber outlet for circulating steel belt. Rollers for driving the steel belt are provided near both the steam chamber inlet and the steam chamber outlet. At least one of the rollers is hollow and has a steam inlet at its shaft end. The steam oven is connected to the steam inlet via a steam passage and the steam enters the inner cavity of the roller. A valve is provided in the steam passage between the steam oven and the steam chamber.

[0008] As a further technical solution of this utility model, the steam passage between the steam oven and the steam inlet is also provided with a condensate discharge port.

[0009] As a further technical solution of this utility model, the steam passage between the steam oven and the steam inlet is also provided with a one-way valve that flows toward the roller.

[0010] As a further technical solution of this utility model, the rollers near the steam box inlet and steam box outlet are both hollow structures, and both are connected to the steam passage through steam inlets set at the shaft ends, and finally connected to the steam oven.

[0011] As a further technical solution of this utility model, the valve is an electric regulating valve.

[0012] As a further technical solution of this utility model, both ends of the roller are provided with steam inlets, which are connected to the steam passage and finally connected to the steam oven.

[0013] As a further technical solution of this utility model, one axial end of the roller is a steam inlet, and the other end is a steam outlet, both of which are connected to the steam oven through a steam passage.

[0014] As a further preferred embodiment of the above technical solution, the steam passage between the steam outlet and the steam oven is equipped with a one-way valve that flows towards the steam oven.

[0015] This utility model features a simple structure, low implementation difficulty, and good implementation effect. It makes full use of the steam in the steamer of the rice noodle roll machine to preheat the steel belt, so that the rice noodle batter can be quickly pre-formed when it is coated on the steel belt. This avoids the problem of the un-coagulated rice noodle batter being carried away by the movement of the steel belt, and eliminates the defect of uneven thickness of the finished rice noodle roll caused by the rice noodle batter being carried away.

[0021] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0022] Combination Figures 1 to 4As shown, the dual-steam structure of the steel belt rice noodle roll machine of this utility model is constituted by the following basic structure: at least one steamer 1, one steaming box 2 for steaming rice noodle rolls, the steaming box 2 is provided with a steaming box inlet 20 and a steaming box outlet 21 to allow the steel belt 4 to circulate in and out of the steaming box 2, the steaming box 2 is directly connected to the steamer 1 through a steam passage 66, and at least one roller 3 for driving the steel belt 4 to rotate, the shaft end of the roller 3 is provided with a stable fitting structure for driving the steel belt 4 and a hollow axial steam inlet 30, and the interior of the roller 3 forms a hollow inner cavity, which is connected to the steamer 1 through the steam passage 66. The inlet 30 is connected and leads to the inner cavity of the roller 3 through the steam inlet 30. A controllable valve 5 is provided on the steam passage 66 between the steam oven 1 and the steam box 2, while the steam passage 66 between the steam oven 1 and the roller 3 may not be equipped with any valve 5 structure. The stable fit structure refers to the blocking structure 32 at both ends of the roller 3 in the length direction to prevent the steel strip 4 from falling off. For example, it can prevent the steel strip 4 from moving along the axial direction of the roller 3 by means of flanges, protrusions, splines, etc. The shaft end of the roller 3 and the frame of the rice noodle machine should also be provided with necessary rolling pairs such as bearings 10, which will not be elaborated here.

[0023] As a necessary structure, the steam inlet 30 of the roller 3 is connected to the steam passage 66 via a dynamic seal to ensure that the continuous rotation of the roller 3 does not cause excessive twisting at the connection between the steam passage 66 and the roller 3, nor does it cause steam leakage. Figure 2 As shown, the roller 3 can have a steam inlet 30 at one end or at both ends to improve the steam introduction efficiency. Furthermore, if necessary, the roller 3 should have a physical structure that allows external steam to flow into its interior due to a pressure difference. In the case of steam inlets 30 at both ends, the roller 3 needs to be separately provided with a discharge port for condensate; or, as... Figure 3 As shown, one end of the roller 3 is configured as a steam inlet 30, and the other end as a steam outlet 33. The steam outlet 33 is reconnected to the steam oven 1. Optionally, a controllable one-way valve 60 with the flow direction towards the steam oven 1 can be set in the steam passage 66 between the steam outlet 33 and the steam oven 1. When steam is generated in the steam oven 1, the steam generated in the steam oven 1 can be pressurized so that it can pass through the one-way valve 60 unilaterally without backflow. This can accelerate the efficiency of steam flow, improve the heating rate of the roller 3, and reduce the condensate generation rate in the roller 3. As a technical supplement, referring to the existing hollow roller structure, the shaft end of the roller 3 is movably connected to the bearing 10, and the steam inlet 30 is rotatably connected to the steam passage 66. Here, a rotary seal or an unsealed method can be used. In the case of an unsealed method, there will be steam leakage and condensate dripping. Usually, a rotary seal pair is used to connect a steam passage 6 connector, which is then connected to the steam passage 66.

[0024] The beneficial effects brought about by the above-mentioned necessary structural settings of this utility model are foreseeable: Since there is no valve 5 structure between the roller 3 and the steamer 1, once the steamer 1 is ready to run and starts, as water vapor is generated, the temperature of the roller 3 will rise along with the steamer 1, so that the roller 3 will start to preheat first, and the steel belt 4 will also be preheated simultaneously. When the temperature of the steamer 1 reaches the required level, the valve 5 is opened, and high-temperature water vapor is transported into the steamer 2. At this time, driving the steel belt 4 to rotate can start the processing and steaming operation of rice noodle rolls. Since the roller 3 can provide heating assistance to the steel belt 4, the steel belt 4 can maintain a suitable temperature after leaving the steamer 2 from the steamer outlet 21 and before entering the steamer 2 from the steamer inlet 20. In this way, when rice flour batter is applied to the surface, it quickly solidifies upon contact with the steel belt 4, resulting in a more stable but not fully solidified shape. At this point, diced meat, scallions, egg, and other toppings can be added. Since the rice flour batter remains heated, once the toppings are added and the rice flour is placed in the steamer 2, the rice flour skin is fully solidified (fully cooked), allowing the toppings to be removed from the steamer in a relatively tender state, ultimately resulting in a high-quality rice flour product. Therefore, this method improves the steaming efficiency of rice flour and, overall, indirectly increases energy utilization efficiency.

[0025] Furthermore, in actual production applications, rice noodle roll equipment usually needs to be kept running, specifically, the steamer 1 needs to be kept running continuously to avoid insufficient steam generation due to water temperature drop. In stages where there is no need for rice noodle roll processing, the temperature of the steamer 1 can be manually lowered to the minimum level that can quickly generate a large amount of steam. At this time, valve 5 is closed, and no more high-temperature steam will be introduced into the steam chamber 2. Instead, the steam will be completely conducted into the roller 3 to keep the steel belt 4 warm. Obviously, the primary function of this operation is to reduce the energy consumption of the equipment. On the other hand, if it is necessary to start making rice noodle rolls again, simply opening valve 5 can quickly raise the temperature of the cooled steam chamber 2 back to the required furnace temperature, thus allowing the process to resume. This avoids the situation where the steel belt 4 needs to be reheated through the steam chamber 2 and waits.

[0026] The above-mentioned structure is reasonably matched and requires few structural elements, so it is very easy to implement and has high structural stability. For existing automated steel belt rice noodle roll making equipment, it will not cause significant obstacles to either new production design or product modification. The steel belt automatic rice noodle roll equipment with the steam structure described in this utility model can basically achieve the technical effect of the technical solution described in this utility model normally because it is difficult for any elements to interfere with the implementation of the above structure in terms of structural principle, thereby improving the work efficiency of customers using the equipment.

[0027] Furthermore, such as Figure 4 As shown, as one direction for improvement, the number of rollers 3 connected through the steam passage 66 of the steam oven 1 is not unique. Considering that the automatic rice noodle roll machine with steel belt 4 usually requires two rollers 3 to drive the reciprocating cycle of the steel belt 4, the rollers 3 at both ends of the steel belt 4's stroke, that is, near the steam box inlet 20 and steam box outlet 21, are all set with hollow inner cavity structures. They are also connected to the steam passage 6 according to the dynamic sealing method of the shaft end and finally connected to the steam oven 1. This ensures that the steel belt 4 is kept at a suitable temperature throughout its journey, which can maximize the service life of the steel belt 4. Whether the steel belt 4 enters or leaves the steam box 2, its surface temperature can be maintained at a certain level, which is convenient for subsequent cooking. This achieves the technical effect of the steel belt 4 being able to keep warm when needed and cool down evenly when not needed, which helps to improve the efficiency of rice noodle roll cooking.

[0028] Furthermore, refer to Figure 1 or Figure 4 As shown, as one direction for improvement, a one-way valve 60 structure with the flow direction towards the roller 3 can be set in the steam passage 66 of the unidirectional roller 3, and the steam generated by the steam oven 1 can be pressurized to ensure that the steam output from the steam oven 1 is only transported to the roller 3 in one direction and will not cause backflow. This maximizes the preheating efficiency and temperature maintenance of the roller 3. Insulation structures are set at the points where the steam passage 66 is connected, such as dynamic seals, to optimize the preheating and insulation performance of the roller 3 within a limited range, reduce the energy consumption during equipment operation, and quickly close the one-way valve 60 when needed to reduce the power of the steam oven 1, thereby reducing energy consumption, or increase the power of the steam oven 1 to ensure that all steam flow can be fully transported into the roller 3 and ensure the preheating rate of the roller 3.

[0029] Furthermore, refer to Figures 1 to 4 As shown in any figure, a condensate drain port 31 is also provided at the connection between the steam inlet 30 and the steam passage 66. The condensate drain port 31 can be further set on the joint between the roller 3 and the steam passage 66. This joint structure is in the form of a three-way connector. In other words, the roller 3 can be set with a condensate drain port 31 as a normally closed drain port. In actual operation, condensation will inevitably occur when the steam conducts heat in the roller 3, resulting in the accumulation of condensate in the roller 3. Therefore, it is necessary to drain the condensate in time through the condensate drain port 31 to avoid the condensate from hindering the subsequent preheating of the roller 3. In addition, it can also avoid the problem of rust on the inner liner of the roller 3 caused by condensate. At the same time, as a mode of simplifying operation, the condensate drain port 31 can be plugged with a plug under normal circumstances. Only when it is necessary to drain the internal condensate, a hose is inserted and the internal water is drained by the principle of siphon.

[0030] Furthermore, as one direction for improvement, the valve 5, which is only connected to the steam passage 66 between the steam box 2 and the steam oven 1, is an electrically controlled regulating valve. Since the temperature of the steam itself is approximately 100°C, if a manually operated mechanical valve is installed without adequate protection measures, the high-temperature steam could easily scald the user's skin if it leaks, or directly burn the user through the heat transfer effect at the valve 5 operating handle. To avoid this situation, as a preferred technical solution where conditions permit, the valve 5 here is an adjustable regulating valve, and a steam leakage sensor is installed at the corresponding position. This not only improves the operating response efficiency of the valve 5 and optimizes the energy consumption structure of the equipment, but also allows for real-time detection of the sealing condition of the steam passage 66. When steam leakage occurs, it can be detected in time and appropriate intervention can be taken to avoid the problem of increased energy consumption caused by excessive steam leakage, and also helps to maintain the efficient operation of the equipment.

[0031] Overall, the technical solution of this utility model is helpful for the efficient use of steam resources in steam oven 1 and for improving the quality of rice noodle rolls produced by the rice noodle roll machine. The overall technical solution has a simple structure, is easy to implement, and has good implementation effect, so it is suitable for promotion and application.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
