[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0025] Embodiment 1

[0026] Reference Figure 1 As shown, the utility model provides a cooling device for rice noodle production, which is used for cooling the rice noodles after they are cooked. The utility model is connected to the existing cooking tunnel, replaces the open cooling device, and sets a closed space for air cooling. A two-stage filtration is also provided to reduce the initial bacteria content of the rice noodles and extend the shelf life of the product.

[0027] Specifically, the cooling device for rice noodle production includes a box body 1, a conveying component, an air inlet component 2 and an air outlet component 4; a closed space is formed inside the box body 1, and its two ends in the extension direction are respectively set as a feed port 1001 and a discharge port 1002; the conveying component is connected to the aging tunnel of the previous process and is arranged through the inside of the box body 1, and the conveying component is used to transport the rice noodles to be cooled from the feed port 1001 into the inside of the box body 1, and then move to the discharge port 1002, and the rice noodles are cooled during the movement.

[0028] Specifically, in the existing rice noodle cooling device, the rice noodles are usually directly exposed to the air environment, and the air flow above the rice noodles is accelerated by a suspended fan to play a cooling role. On the one hand, foreign particles and bacteria in the air are easy to contaminate the rice noodles. On the other hand, the increase in air flow rate brought by the fan has a limited cooling effect on the rice noodles, and the cooling area is small and the cooling effect is weak. Therefore, in a preferred embodiment of the utility model, the rice noodles are arranged inside a closed box 1 to improve the processing cleanliness, and the flow of clean air is achieved through the air inlet component 2 and the air outlet component 4, and the gas flow range covers the surface of the rice noodles.

[0029] Furthermore, the positions where the air inlet assembly 2 and the air outlet assembly 4 are connected to the box body 1 are located on both sides of the box body 1, wherein the air inlet assembly 2 is located on the side close to the discharge port 1002 in the extension direction of the box body 1, and the air outlet assembly 4 is located on the side close to the feed port 1001 in the extension direction of the box body 1. The gas enters the inside of the box body 1 from the air inlet assembly 2, and flows out to the outside of the box body 1 from the air outlet assembly 4. The flow direction of the gas in the box body 1 is opposite to the moving direction of the rice noodles in the box body 1, forming a reverse flow, thereby improving the cooling effect and cooling efficiency.

[0030] Furthermore, the air inlet assembly 2 includes a first pipeline 21 and a second pipeline 22, one end of the first pipeline 21 is connected to the interior of the housing 1, and the other end of the first pipeline 21 is connected to the air outlet of the fan 3; one end of the second pipeline 22 is connected to the air inlet of the fan 3, and the other end of the second pipeline 22 is connected to the atmosphere, and the air is sucked into the interior of the housing 1 through the fan 3. It should be noted that a filter 2201 is provided at one end of the second pipeline 22 connected to the atmosphere, which is used to filter most of the large particles in the air; a filter 31 is also provided in the fan 3, and the filter 31 is used to efficiently filter most of the bacteria and microorganisms. In the preferred embodiment of the utility model, the cleanliness of the cooling air is ensured by a two-stage filtration setting, so as to avoid contamination of the rice noodles, extend the shelf life of the rice noodles, and realize clean production.

[0031] Furthermore, one end of the air outlet component 4 is connected to the interior of the box body 1, and the other end is connected to an external processing device; in some embodiments, the connection positions of the air inlet component 2 and the air outlet component 4 with the box body 1 are both located on the same side of the box body 1 in the vertical direction, and are preferably located above the conveying component, so that the cooling air in the box body 1 can enter and exit above the rice noodles to achieve circulation.

[0032] Next, in some embodiments, one end of the air outlet component 4 away from the box body 1 is connected to the ripening tunnel in the previous process; the cooling air absorbs heat inside the box body 1 and the temperature rises, and the air outlet component 4 is connected to the ripening tunnel to discharge the heated air, and the ripening tunnel is filled with high-temperature steam, and the ripening tunnel body is provided with an air outlet to discharge the internal steam; the process effects of the ripening step and the cooling step do not affect each other, and the rice noodles can remain fully sealed during the process from ripening to cooling, and the cleanliness is higher.

[0033] Specifically, the cooling device for rice noodle production also includes a sterilization component 5, which is fixed to the inner wall of the box 1 and arranged toward the conveying component; in some embodiments, the sterilization component 5 is configured as an ultraviolet lamp 51, and the ultraviolet lamp 51 is hung on the top wall of the box 1 through a hook 52. The ultraviolet lamp 51 is used to irradiate the cooked rice noodles and the conveying component for disinfection and sterilization again to control the growth of microorganisms.

[0034] Specifically, the cooling device for rice noodle production further comprises a viewing window 6, which is embedded in the side wall of the box body 1 and is used for observing the cooling and production conditions of the rice noodles in real time.

[0035] Embodiment 2

[0036] The second embodiment of the utility model provides a cooling device for rice noodle production, which is different from the first embodiment in that the cooling device for rice noodle production described in the second embodiment is provided with a partition 13. The partitions 13 have several groups, and are all located inside the box 1; the partitions 13 divide the inside of the box 1 into at least two groups of closed chambers along its extension direction; in the preferred embodiment of the second embodiment, the partitions 13 have two groups, dividing the box 1 into three groups of closed chambers; in other embodiments, the number of the partitions 13 can be set according to the actual production requirements such as the amount of rice noodles, the temperature after cooking and the cooling temperature, but is not limited thereto.

[0037] Specifically, refer to Figure 1 As shown, the partition 13 is correspondingly provided with a feeding port 1301 for the conveying component and rice noodles to pass through. The feeding port 1301 is arranged opposite to the feed port 1001 and the discharge port 1002 in the extension direction of the box body 1 and has the same shape. The conveying component transports the cooked rice noodles in the horizontal direction, passing through the feed port 1001, the feeding port 1301 and the discharge port 1002 in sequence.

[0038] Next, the vertical opening widths of the feed port 1001, the discharge port 1002 and the feed port 1301 are all 15 cm, and the horizontal opening widths are consistent with the width of the box body 1; when the conveying component transmits rice noodles, the bottom and sides are in contact with the feed port 1001, the feed port 1301 and the discharge port 1002, and the outer wall of the box body 1 except the feed port 1001 and the discharge port 1002 is set to a closed state to reduce the entry of bacteria.

[0039] Specifically, the inventors of this case have found that, due to cooling needs, the extension length of the existing cooling device along the rice noodle transmission direction is relatively long. In order to improve the cooling effect, the prior art uses multiple fans suspended in sections above, but the cooling area that can be covered is still limited; therefore, in the preferred implementation of Example 2, each of the closed chambers corresponds to connecting one of the air inlet components 2 and one of the air outlet components 4, and the air inlet components 2 in each group of the closed chambers are arranged close to the side of the outlet port 1002, and the air outlet components 4 are arranged close to the feed port 1001. One side is arranged; the flow direction of the cooling wind in each of the closed chambers is opposite to the transmission direction of the rice noodles, forming a countercurrent; on the one hand, after the box body 1 is divided, the extension length of each closed chamber is reduced, the airflow direction of the cooling wind is easier to control, and it is easier to form a countercurrent effect; it can completely cover the surface of the rice noodles, and cool the entire range above the rice noodles, with a uniform cooling effect and a larger area; on the other hand, three chambers with different temperatures are formed by arranging the partition 13, and the temperature decreases step by step along the transmission direction, so that the rice noodles are cooled in sections and partitions, local temperature runaway is prevented, and the cooling effect is better.

[0040] Furthermore, in the preferred implementation manner of Example 2, each of the closed chambers is provided with a group of the sterilization components 5 and a group of the windows 6; dual control of filtration and sterilization is formed through the filter 2201 and the filter 31 of the air inlet component 2, and the sterilization component 5. Compared with the prior art, the embodiment of the utility model realizes closed clean production, and the initial bacterial count within 2 hours of rice noodle production is less than 100 CFU / g, the shelf life of fresh wet round noodles is extended, and the food safety is significantly improved.

[0041] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
