Description

Technical Field

[0001] The present invention relates to the technical field of drying equipment, in particular to an airflow guide device and a drying chamber. Background Art

[0002] The production process of ramen noodles mainly includes steps such as dough mixing, pretreatment, shaping, and drying. Among them, the drying process is a key step in the ramen production process, which directly affects the final moisture content, taste, and shelf life of the ramen. In the traditional ramen drying process, the noodles are usually hung in a drying oven for drying. The drying process is generally divided into two stages: in the first stage, a high-temperature airflow is blown into the drying oven, causing the moisture on the surface of the noodles to evaporate slowly. In the second stage, the airflow is blown into the drying oven after being heated and dehumidified, accelerating the evaporation of moisture from the noodles. During this stage, the airflow temperature is usually maintained at 50-55 degrees Celsius. In the high temperature and low humidity environment, the moisture in the noodles evaporates rapidly, reducing the noodles to a lower moisture content.

[0003] However, existing drying technology uses a high-temperature, low-humidity airflow directly into the drying chamber during the second stage, blowing downwards across the surface of the noodles. This airflow forms a single stream through the outlet. At the end of the drying process, when the noodles have reached a lower moisture content, the strong airflow continuously impacts the hooked portion of the noodles, easily causing them to break and become brittle. Summary of the Invention

[0004] In response to the deficiencies of the prior art, the present invention provides an airflow guide device and a drying chamber, which solves the problem in the existing drying box that during the drying process of ramen noodles, strong airflow of high temperature and low humidity blows directly on the hooked part of the top of the noodles, which easily causes the noodles to break and become crispy.

[0014] Preferably, the air inlet baffles located on both sides of the top of the air baffle are respectively located above the first air outlet cavity and the second air outlet cavity.

[0036] To better explain the present invention and facilitate understanding, the present invention is described in detail below through specific embodiments in conjunction with the accompanying drawings. The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Various changes can be made to the embodiments as long as the effects of the present invention can be exerted.

[0037] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process.

[0038] like Figures 1 to 10 As shown, an embodiment of the present application proposes an air flow guiding device, including an air flow guiding unit 100, which is used to guide the hot air flow in the pipeline into a drying device to remove liquid from the products in the device and dry them. For example, it is used in a noodle processing device. The air flow guiding units 100 are arranged in an array on the noodle processing device, and the hot air flow in the pipeline is dispersed into multiple changeable air flows to act on the dried noodles, so as to prevent the noodles from being broken and crispy due to local excessive dehydration caused by a single air flow ejection position.

[0039] Specific reference Figure 1As shown, in this embodiment, the air flow guide unit 100 includes a first pipe 2 and a second pipe 3. In two adjacent air flow guide units 100, the second pipe 3 is connected to the first pipe 2 of the previous air flow guide unit 100. When multiple air flow guide units 100 are connected in series, air can be supplied to multiple air flow guide units 100 through one pipe.

[0040] Furthermore, the system includes a connecting pipe 4 and an inner ventilation housing 5 connected in parallel between the first pipe 2 and the second pipe 3. An intake pipe 10 and a return pipe 8 are connected to either side of the inner ventilation housing 5. A three-way solenoid valve 9 connects the first pipe 2, one end of the connecting pipe 4, and the intake pipe 10. A three-way valve 7 connects the second pipe 3, the other end of the connecting pipe 4, and the return pipe 8. This parallel connection allows the airflow to form a first-direction flow path and a second-direction flow path. This creates airflow entering the inner ventilation housing 5 from different directions and simultaneously delivering it to the third pipe 3, allowing the remaining airflow to continue to the next airflow guide unit 100.

[0041] The first direction flow path is that the airflow in the first pipe 2 enters the inner ventilation shell 5 through the air intake pipe 10; Figure 2 As shown, the three-way solenoid valve 9 forms left and right passages, and the air flow in the first pipe 2 enters the inner ventilation shell 5 through the air intake pipe 10 and flows into the second pipe 3.

[0042] The second direction flow path is to enter the inner ventilation shell 5 through the connecting pipe 4 and the return pipe 8; Figure 4 As shown, the three-way solenoid valve 9 forms an upper right passage, and the air flow in the first pipe 2 enters the second pipe 3 through the connecting pipe 4 and the three-way valve 7 and enters the inner ventilation shell 5 through the return air pipe 8.

[0043] Furthermore, the airflow guide unit 100 includes a housing 1, with a first conduit 2 and a second conduit 3 connected to opposite ends of the housing 1, a connecting conduit 4 and an inner ventilation housing 5 disposed within the inner cavity of the housing 1, and an air outlet pipe 11 extending out of the housing 1. This allows the aforementioned components to be integrated into the housing 1, facilitating assembly of the airflow guide unit 100 within the drying apparatus.

[0044] Reference Figure 3 and Figure 5In this embodiment, a partition 6 is provided in the inner cavity of the inner ventilation shell 5. The partition 6 is arranged horizontally to divide the inner cavity of the inner ventilation shell 5 into an upper cavity 15 and a lower cavity 16 distributed vertically; a plurality of air outlet pipes 11 are provided on the inner ventilation shell 5, and the air outlet pipes 11 are connected to the lower cavity 16. This arrangement can divert the airflow. When the airflow flows along the first direction flow path, the airflow entering the upper cavity 15 continues to flow into the second pipe 3, and the airflow entering the lower cavity 16 can flow out through the air outlet pipes 11. It should be noted that when the airflow flows along the second direction flow path, it is diverted through the tee 7, and the airflow entering the inner ventilation shell 5 all flows out through the air outlet pipes 11.

[0045] Furthermore, in order to make the hot air flow in the pipeline disperse and flow out in multiple changeable air flows, an air baffle 12 is rotatably connected and arranged in the outlet pipe 11 in this embodiment. Under normal conditions, the air baffle 12 is arranged vertically, in the same direction as the outlet pipe 11. The air baffle 12 divides the outlet pipe 11 into a first air outlet clamp chamber 13 and a second air outlet clamp chamber 14; and a plurality of vent holes 24 are opened on the air baffle 12, so that part of the air flow flowing out of the first air outlet clamp chamber 13 or the second air outlet clamp chamber 14 passes through and flows out; wherein, the air flow in the first pipeline 2 enters the inner cavity through one side or the other side of the inner ventilation shell 5 and flows into the second pipeline 3, and at the same time, part of the air flow blows onto the air baffle 12 to change the opening of the first air outlet clamp chamber 13 and the second air outlet clamp chamber 14, so that the air flow flows out along the first air outlet clamp chamber 13, the second air outlet clamp chamber 14 and the vent holes 24 on the air baffle 12.

[0046] It needs to be explained in detail that Figure 2 and Figure 4 As shown, when airflow within lower chamber 16 strikes air baffle 12, it flips, changing the openings of first and second outlet chambers 13, 14. Since airflow enters from inlet duct 10 and return duct 8 in different directions, the airflow direction of inner vent housing 5 can be adjusted via three-way solenoid valve 9. As the airflow direction continuously changes, the flipping direction of air baffle 12 also changes, continuously altering the openings of first and second outlet chambers 13, 14. This causes airflow to alternate between rapid and slow jets within first and second outlet chambers 13, 14, and to exit through vent holes 24 in a dispersed manner. This creates a multi-stream, variable airflow dispersion effect on the noodles, effectively enhancing contact with the noodles.

[0047] Reference Figures 2 to 5As shown, in order to improve the effect of alternating rapid and slow airflow ejection in the first air outlet cavity 13 and the second air outlet cavity 14, an air inlet baffle 19 is provided between the top sides of the air baffle 12 and the outer edge of the air outlet pipe 11 to adjust the amount of air entering the first air outlet cavity 13 and the second air outlet cavity 14.

[0048] Specifically, the air intake baffle 19 includes a first arc-shaped plate 191 and a second arc-shaped plate 192 that overlap each other. The first arc-shaped plate 191 and the second arc-shaped plate 192 are fixed to the air baffle 12 and the inner ventilation shell 5 respectively. The first arc-shaped plate 191 and the second arc-shaped plate 192 are respectively provided with a second opening 194 and a first opening 193. Figure 6 and Figure 7 As shown, when the air baffle 12 is blown by the airflow and swings, the first arc-shaped plate 191 and the second arc-shaped plate 192 on both sides are misaligned, so that the second opening 194 and the first opening 193 on one side constitute the first clamping hole 195, and the second opening 194 and the first opening 193 on the other side constitute the second clamping hole 196 and the third clamping hole 197.

[0049] Reference Figure 3 and Figure 5 The air inlet baffles 19 on both sides of the top of the air baffle 12 are respectively located above the first air outlet cavity 13 and the second air outlet cavity 14. Figure 3 and Figures 5 to 7 , exemplarily pointing out that the outlet air pipe 11 is an embodiment of blowing out in a switchable multi-flow dispersed manner.

[0050] For example, Figure 3 As shown, when the air flow blows into the lower cavity 16 from the right side and blows onto the air baffle 12, the air baffle 12 is turned over. At this time, the opening of the first air outlet clamp cavity 13 is larger than the opening of the second air outlet clamp cavity 14. At this time, the first curved plate 191 and the second curved plate 192 located above the first air outlet clamp cavity 13 are as shown in FIG. Figure 6 As shown, the two surfaces are almost completely overlapped. At this time, the second opening 194 and the first opening 193 on the surface of the two constitute the first clamping hole 195, so that less airflow enters the first air outlet clamping cavity 13 with a larger opening, forming a slow airflow ejection; the first arc-shaped plate 191 and the second arc-shaped plate 192 located above the second air outlet clamping cavity 14 are as shown. Figure 7 As shown in the figure, the second opening 194 and the first opening 193 on the surface of the two constitute the second clamping hole 196 and the third clamping hole 197, so that more air flows into the second air outlet clamping cavity 14 with a smaller opening, forming a rapid air flow; at the same time, the rapid air flow in the second air outlet clamping cavity 14 blows at the bottom of the air baffle 12 and is ejected through the vent holes 24 in a dispersed air flow.

[0051] For example, Figure 5As shown, when the air flow is blown into the lower cavity 16 from the left side and blows onto the air baffle 12, the air baffle 12 is turned over. At this time, the opening of the second air outlet clamp cavity 14 is greater than the opening of the first air outlet clamp cavity 13. At this time, the first curved plate 191 and the second curved plate 192 located above the first air outlet clamp cavity 13 are as shown. Figure 7 As shown, the second opening 194 and the first opening 193 on the surfaces of the two components form the second clamping hole 196 and the third clamping hole 197, allowing more air to enter the first air outlet clamping cavity 13 with a smaller opening, forming a rapid air flow; the first arc-shaped plate 191 and the second arc-shaped plate 192 located above the second air outlet clamping cavity 14 are as shown. Figure 6 As shown, they are almost completely overlapped. At this time, the second opening 194 and the first opening 193 on the surfaces of the two constitute the first clamping hole 195, so that less airflow enters the second air outlet clamping cavity 14 with a larger opening, forming a slow airflow ejection; at the same time, the rapid airflow in the first air outlet clamping cavity 13 blows on the bottom of the air baffle 12 and is ejected through the ventilation holes 24 in a dispersed airflow.

[0052] Reference Figure 3 and Figure 5 To facilitate continued airflow within lower chamber 16, in this embodiment, baffle 6 is bent upward at the location of air baffle 12 to form a curved portion 17. Curved portion 17 and air intake baffle 19 form an arcuate cavity 18. A windward plate 20 is located at the top of air baffle 12 within arcuate cavity 18. This allows airflow within lower chamber 16 to pass through arcuate cavity 18 and strike windward plate 20, causing air baffle 12 to flip.

[0053] Reference Figure 8 As shown, the surface of the air baffle 12 is formed with a windward surface 21, and a plurality of plates 23 are provided on the windward surface 21. A plurality of ventilation holes 24 are provided on each plate 23. The adjacent plates 23 and each plate 23 are connected to the air baffle 12 by a rubber sheet 22. When the airflow blows to the windward surface 21, each plate 23 is bent and deformed by the rubber sheet 22 to form a plurality of shapes, as shown in FIG. Figure 9 As shown, the multiple plates are formed into arc and / or "S" shape and / or wave shape. As the plates 23 on each air baffle 12 form different shapes, the air flow passing through the air holes 24 forms different flow states, thereby presenting the effect of multiple air flows being ejected in a dispersed manner. Figure 10As shown, each vent hole 24 is rotatably connected to an air duct 26. Vanes 25 are positioned on the outside of each end of the air duct 26. Paddles 27 are positioned obliquely within the interior of the air duct 26, creating a gap between the paddles 27 and the inner wall of the air duct 26 for airflow to pass through. When a rapid airflow strikes the windward surface 21 of the air baffle 12, it contacts the vanes 25, causing the air duct 26 to spin. The airflow passing through the gap is then driven by the spinning air duct 26 and ejected continuously and evenly along its circumference. This, combined with the various configurations of the blades 23, enhances the dispersed airflow effect.

[0054] In addition, this embodiment also proposes a drying room, referring to Figure 11 As shown, the above-mentioned air flow guide device and the drying box 200 are included, the air flow guide units 100 are arranged in an array above the drying box 200 , and the air outlet pipe 11 extends into the drying box 200 .

[0055] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
