[0033] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with embodiments, but the scope of protection claimed in the utility model is not limited to the following specific embodiments.

[0034] refer to Figure 1 and Figure 2 A rice noodle extruder for cooling extruded rice noodles comprises a processing table 11, a rice noodle feeding device 12, a rice noodle forming box 21 and a rice noodle cooling device, wherein the rice noodle feeding device 12, the rice noodle forming box 21 and the rice noodle cooling device are all installed on the processing table 11. The rice noodle forming box 21 is connected to the rice noodle feeding device 12, and the rice noodle feeding device 12 comprises a screw feeder connected to the rice noodle forming box 21. The rice noodle forming box 21 is provided with two rice noodle extrusion areas, and the rice noodle cooling device comprises a bellows 31, an air inlet 32 ​​is provided in the middle of the bellows 31, a fan 33 connected to the air inlet 32 ​​is installed in the bellows 31, and two cooling air outlets 34 are respectively located at two ends of the bellows 31, and the cooling air outlets 34 face the rice noodle extrusion area, and the two cooling air outlets 34 correspond to the two rice noodle extrusion areas one by one. The rice noodle extrusion area is provided with a plurality of inclined hole rows 23, which are composed of a plurality of extrusion holes 22 connected to the inside of the rice noodle forming box 21, and the angle between the inclined hole row 23 and the cooling air outlet 34 is 0°-90°.

[0035] The wind box 31 is fixedly connected with an air guide plate 35, and the air guide plate 35 extends in the direction of the cooling air outlet 34. An air induction plate 36 is fixedly connected to one end of the air guide plate 35 close to the air inlet 32, and one end of the air induction plate 36 away from the air guide plate 35 is inclined in the direction close to the air inlet 32. A plurality of air guide plates 35 are provided, and the plurality of air guide plates 35 are arranged in the direction away from the air inlet 32. The air induction plates 36 are staggered from the central axis of the cooling air outlet 34, and the air induction plate 36 farther from the air inlet 32 ​​among any two air induction plates 36 is closer to the central axis of the air inlet 32.

[0036] The processing table 11 is fixedly connected to a support frame 13, and the support frame 13 is provided with a cooling water tank 14 located below the rice noodle extrusion area, and water is provided in the cooling water tank 14. The air guide plate 35 is fixedly connected to a heat conducting plate 37, and the heat conducting plate 37 extends into the cooling water tank 14. The processing table 11 is fixedly connected to a baffle 15, and the baffle 15 is located on a side of the rice noodle extrusion area away from the cooling air outlet 34. The lower end of the baffle 15 is located above the cooling water tank 14.

[0037] This embodiment has the following advantages:

[0038] The rice noodle feeding device 12 squeezes the rice noodle into the rice noodle forming box 21, and the rice noodle in the rice noodle forming box 21 is squeezed out from the extrusion hole 22 in the rice noodle extrusion area to form vermicelli. The fan 33 injects air into the bellows 31 through the air inlet 32, and the air in the bellows 31 flows and is discharged from the cooling air outlet 34, and the heat of the rice noodle is absorbed by the flowing air, so as to realize the function of air cooling and heat dissipation and temperature reduction of the extruded rice noodle. By arranging at least two rice noodle extrusion areas and the cooling air outlet 34, the effect of improving the cooling effect on the rice noodle can be played, and the advantage of better cooling effect on the rice noodle is achieved, which is conducive to improving the processing efficiency of the rice noodle on the basis of ensuring the cooling effect of the rice noodle.

[0039] By setting the air guide plate 35, the air in the bellows 31 is guided to flow toward the cooling air outlet 34, so that the air in the bellows 31 can flow more smoothly during the discharge process, thereby ensuring the air flow rate and the heat dissipation effect on the rice noodles.

[0040] The air induction plate 36 can guide the air flow. The end of the air induction plate 36 away from the air guide plate 35 is inclined toward the air inlet 32, so that the air entering the wind box 31 from the air inlet 32 ​​can be guided to flow more smoothly to the air guide plate 35, thereby reducing the resistance encountered during the air flow, thereby ensuring the air flow rate and the heat dissipation effect on the rice noodles.

[0041] By providing a plurality of air guide plates 35, the air in the bellows 31 can flow more smoothly during discharge, thereby ensuring the air flow rate and the heat dissipation effect on the rice noodles.

[0042] The closer the air inlet 32 ​​is to the air inlet 32, the farther it is from the central axis of the air inlet 32. Therefore, when the air inlet 32 ​​is facing upward, the air inlet 36 close to the air inlet 32 ​​is located on the outside, while the air inlet 36 far from the air inlet 32 ​​is located on the inside, thereby preventing the air inlet 36 close to the air inlet 32 ​​from completely blocking the air, ensuring that the air can flow evenly to each air inlet 36, so that the air can be evenly discharged from the cooling air outlet 34, thereby further ensuring the air cooling efficiency of the rice noodles.

[0043] After being squeezed out, the rice noodles fall downward into the cooling water tank 14, and the water in the cooling water tank 14 further cools the rice noodles, which can improve the cooling effect on the rice noodles and prevent the rice noodles from being deformed and sticking after being squeezed out.

[0044] As rice noodles continue to enter the cooling water tank 14, the residual heat of the rice noodles will increase the water temperature in the cooling water tank 14. After the heat conducting plate 37 absorbs the heat of the water in the cooling water tank 14, the heat can be transferred to the air guide plate 35 through the heat conducting plate 37. When the air flows through the air guide plate 35, the heat on the air guide plate 35 is taken away, thereby achieving the function of dissipating heat from the water in the cooling water tank 14, ensuring the cooling effect of the water in the cooling water tank 14 on the rice noodles.

[0045] The temperature of the air is relatively high after passing through the rice noodles. The baffle 15 located on the side of the rice noodle extrusion area away from the cooling air outlet 34 can block the air with relatively high temperature, thereby preventing people from being accidentally scalded.

[0046] When water vapor condenses on the baffle 15 to form water droplets, the water droplets can flow to the lower end of the baffle 15 and then drip downward into the cooling water tank 14 , thereby collecting the water droplets on the baffle 15 .

[0047] The inclined hole row 23 is inclined relative to the cooling air outlet 34, thereby preventing the rice noodles close to the cooling air outlet 34 from completely blocking the air, so that the rice noodles extruded from the extrusion hole 22 can be cooled more evenly, thereby ensuring the cooling effect on the rice noodles.

[0048] According to the disclosure and teaching of the above specification, the technicians in the field of the utility model can also change and modify the above implementation. Therefore, the utility model is not limited to the specific implementation methods disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the utility model.
