Description

Technical Field

[0001] This invention relates to a cooling device for rice noodle production, belonging to the technical field of rice noodle production equipment. Background Technology

[0002] Existing rice noodle cooling devices, such as the Chinese Utility Model Patent "Authorization Announcement No.: CN209660376U; Application Publication Date: November 22, 2019; Title: A Cooling Device for Rice Noodle Processing", involve conveying the cooked rice noodles via a conveyor belt, first through a water-cooling chamber and then through an air-cooling chamber. The water-cooling chamber can only cool the rice noodles on one side, while the air-cooling chamber is equipped with an upward-pushing device for the rice noodles. This device can push and disperse the rice noodles. Although the upward-pushing device can accelerate the cooling of the rice noodles to a certain extent, due to the limitations of its pushing action, it cannot achieve the flipping of the rice noodles during the cooling process. This solution can only cool the rice noodles on one side, resulting in inconsistent cooling speeds and degrees in different parts of the rice noodles, which affects the overall taste and quality of the rice noodles. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned technical deficiencies of existing rice noodle production cooling devices by providing a new cooling device for rice noodle production. This cooling device can automatically tumble the rice noodles on the conveying device during water cooling and air cooling, allowing direct cooling of all surfaces of the rice noodles. This ensures uniform cooling of all surfaces of the rice noodles and effectively improves their taste and quality.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0005] A cooling device for rice noodle production includes a housing. Inside the housing is a rice noodle conveying device and a water-cooling device and an air-cooling device arranged along the conveying direction of the rice noodle conveying device. The rice noodle conveying device includes two conveying chains arranged symmetrically in the conveying direction of the rice noodles. The two conveying chains are mounted inside the housing via rotating shafts with drive gears at both ends. Several rice noodle frames are equidistantly arranged between the two conveying chains. The rice noodle frames are rotatably mounted on the two conveying chains via pivot pins on the left and right sides. The pivot pins of the rice noodle frames are equipped with gears. The left and right inner sidewalls of the housing are provided with racks that mesh with the gears. The left and right inner sidewalls of the housing are also provided with pressure strips corresponding to the racks. The pressure strips limit the pivot pins, so that the gears and racks always remain engaged.

[0006] By adopting the above technical solution, a cooling device for rice noodle production is provided. The cooling device disperses the rice noodles in a rice noodle frame. When the rice noodle frame passes through the water cooling position and the air cooling position, the meshing of the gear and rack on the rotating pin can automatically cause the rice noodle frame on the conveying device to flip, thereby achieving uniform cooling of all sides of the rice noodles, which can effectively improve the taste and quality of the rice noodles.

[0007] A further feature of the present invention is that the rice noodle frame includes a bottom frame and a frame cover for sealing the opening of the bottom frame. Both the bottom frame and the frame cover are woven from stainless steel wire or are composed of a plate with evenly distributed through holes.

[0008] By adopting the above technical solution, a rice noodle frame is provided that can effectively limit the rice noodles while ensuring that cold water and cold air can enter to cool the rice noodles.

[0009] A further feature of the present invention is that: a U-shaped support plate is provided on the outer side of the rotating shaft at both ends of the conveying device, the two U-shaped support plates are arranged with their openings facing each other, the width of the U-shaped support plate is smaller than the gap between the two conveying chains, the U-shaped support plate is fixed between the two conveying chains by a connector, and the U-shaped support plate can limit whether the rice noodle frame is flipped.

[0010] By adopting the above technical solution, U-shaped support plates are installed at both ends of the conveying device. The U-shaped support plates can limit the rotation of the rice noodle frame and ensure that the opening of the rice noodle frame is facing the correct direction when it reaches the feeding position and the unloading position.

[0011] A further feature of the present invention is that the lower straight plates of the two U-shaped support plates are connected by connecting straight plates.

[0012] By adopting the above technical solution, the straight plates on the lower side of the two U-shaped support plates are connected by straight connectors. This solution can effectively ensure that the rice noodle frame does not deflect when it is transferred to the lower side, and can effectively ensure that the opening of the rice noodle frame is facing the correct direction when it reaches the feeding position, thus effectively ensuring the stable and reliable operation of the entire device.

[0013] A further feature of the present invention is that the frame cover is hinged to the opening of the bottom frame by a torsion spring, the torsion spring allowing the frame cover to be tightly fastened to the opening of the bottom frame, and the torsion spring is located on the forward side of the rice noodle frame in the upper section of the conveyor chain.

[0014] By adopting the above technical solution, a torsion spring is used to install the frame cover at the opening of the bottom frame. The torsion spring allows the frame cover to close automatically, ensuring that the frame cover is always tightly fastened to the opening of the bottom frame. This not only improves the convenience of closing the frame cover, but also effectively prevents the rice noodles in the rice noodle frame from falling out during rotation.

[0015] A further provision of the present invention is that: an upward lifting device for the frame cover is provided above the U-shaped support plate on the feeding side of the conveying device, and a downward pulling device for the frame cover is provided below the U-shaped support plate on the unloading side of the conveying device. Both the upward lifting device and the downward pulling device consist of an obliquely arranged tension cylinder, a hook pull crossbar fixed to the end of the extension rod of the tension cylinder, and a spring for pushing the cylinder body of the tension cylinder toward the conveying chain.

[0016] By adopting the above technical solution, an upward lifting device and a downward pulling device that can automatically open the rice noodle frame are provided. These two frame opening devices, together with the support of two U-shaped support plates, can open the frame cover at the feeding and unloading positions to realize the feeding and unloading of rice noodles.

[0017] A further feature of the present invention is that only the upper conveyor chain is equipped with a rack and a pressure bar, the rack and the pressure bar are located on the lower and upper sides of the pivot pin respectively, the two ends of the pressure bar are located outside the two ends of the conveyor chain respectively, and the pressure bar is located between the two U-shaped support plates.

[0018] By adopting the above technical solution, only the upper section of the conveyor chain is equipped with a rack and a pressure bar. The combination design of the rack and the pressure bar allows the rice noodle frame to rotate during cooling and also provides vertical support for the conveyor chain. This can alleviate the potential breakage risk caused by excessive load on the middle section of the conveyor chain due to the lack of vertical support in the middle. The design of setting the pressure bar and the rack on the outside and inside of the pivot pin respectively ensures that the gear of the pivot pin and the rack are fully engaged. The pressure bar also has a guiding function for the rice noodle frame, making it easy for the gear of the pivot pin and the rack to smoothly complete the engagement from the separated state.

[0019] A further feature of the present invention is that the water-cooling device and the air-cooling device are separated by a curtain, and a partition connecting the left and right inner walls of the outer shell is provided inside the conveyor chain directly below the curtain, and a partition connecting the bottom plate of the outer shell and the left and right inner side walls is provided on the bottom plate of the outer shell.

[0020] By adopting the above technical solution, the water-cooling device and the air-cooling device and the space in which they operate are separated inside the casing, which can effectively reduce the impact of water vapor in the water-cooling device on the air-cooling drying.

[0021] A further feature of the present invention is that the interior of the bottom frame is divided into multiple independent rice noodle placement spaces by several longitudinal partitions.

[0022] By adopting the above technical solution, multiple rice noodle placement spaces are horizontally arranged within the bottom frame. This design increases the rice noodle capacity of the rice noodle frame and effectively separates the rice noodles, preventing them from clumping together during flipping and reducing cooling efficiency. This solution improves cooling efficiency while ensuring cooling quality.

[0023] A further configuration of the present invention is as follows: the water spray nozzle of the water cooling device is located above the conveying device, the fan of the air cooling device is located above the conveying device, and a water collection tank is provided below the water cooling device and the air cooling device. The water in the water collection tank is filtered and then pumped to the water spray nozzle to cool the rice noodles.

[0024] By adopting the above technical solution, both water cooling and air cooling are implemented in a top-down manner, which not only facilitates the arrangement of various devices, but also effectively avoids water vapor from splashing and affecting the air-cooled dried rice noodles.

[0025] The main beneficial effects of this invention are:

[0026] 1. The present invention's cooling device disperses rice noodles in a rice noodle frame. When the rice noodle frame passes through the water-cooling and air-cooling positions, the meshing of the gear and rack on the rotating pin automatically causes the rice noodle frame on the conveying device to flip, thereby achieving uniform cooling of all sides of the rice noodles and effectively improving the taste and quality of the rice noodles.

[0027] 2. The present invention is equipped with U-shaped support plates at both ends of the conveying device. The U-shaped support plates can limit the rotation of the rice noodle frame to ensure that the opening of the rice noodle frame is facing the correct direction when it reaches the feeding position and the unloading position.

[0028] 3. In this invention, the straight plates on the lower side of the two U-shaped support plates are connected by straight connectors. This solution can effectively ensure that the rice noodle frame does not deflect when it is transferred to the lower side, and can effectively ensure that the opening of the rice noodle frame is facing the correct direction when it reaches the feeding position, thus effectively ensuring the stable and reliable operation of the entire device.

[0029] 4. In this invention, only the upper section of the conveyor chain is equipped with a rack and a pressure bar. The combination of the rack and the pressure bar allows the rice noodle frame to rotate during cooling and also provides vertical support for the conveyor chain. This can alleviate the potential breakage risk caused by excessive load on the middle section of the conveyor chain due to the lack of vertical support in the middle. The design of placing the pressure bar and the rack on the outside and inside of the pivot pin respectively ensures that the gear of the pivot pin and the rack are fully engaged. The pressure bar also has a guiding function for the rice noodle frame, making it easy for the gear of the pivot pin and the rack to smoothly complete the engagement from the separated state.

Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Example

[0040] like Figures 1 to 7 As shown, a cooling device for rice noodle production includes an outer shell 1. Inside the outer shell 1 is a rice noodle conveying device and a water cooling device 4 and an air cooling device 5 arranged along the conveying direction of the rice noodle conveying device. A feed inlet 11 is provided on the top plate at the left end of the outer shell 1, and a discharge outlet 12 is provided on the bottom plate at the right end of the outer shell 1. The water cooling device and the air cooling device are separated by a curtain 61. Directly below the curtain 61, inside the conveyor chain 23, a partition 62 is provided connecting the left and right inner walls of the outer shell 1. A partition 62 is provided on the bottom plate of the outer shell 1 connecting the bottom plate of the outer shell 1 and the left and right inner side walls. The water spray nozzle of the water cooling device 4 is located above the conveying device, and the fan of the air cooling device 5 is located above the conveying device. A water collection tank 7 is provided below the water cooling device. The water in the water collection tank 7 is filtered and then pumped to the water spray nozzle to cool the rice noodles.

[0041] The rice noodle conveying device includes two conveying chains 23 arranged symmetrically in the direction of rice noodle conveying. The two conveying chains 23 are mounted inside the housing 1 through rotating shafts 21 with drive gears 22 at both ends. Several rice noodle frames 24 are equidistantly arranged between the two conveying chains 23. The rice noodle frames 24 are rotatably mounted on the two conveying chains 23 through pivot pins 244 on the left and right sides. The pivot pins 244 of the rice noodle frames 24 are equipped with gears 245. The left and right inner sidewalls of the housing 1 are equipped with racks 27 that mesh with the gears 245. The left and right inner sidewalls of the housing 1 are also equipped with pressure strips 28 corresponding to the racks 27. The pressure strips 28 limit the pivot pins 244, so that the gears 245 and the racks 27 are always meshed.

[0042] The rice noodle frame 24 includes a base frame 241 and a cover 242 for sealing the opening of the base frame 241. Both the base frame 241 and the cover 242 are woven from stainless steel wire. The interior of the base frame 241 is divided into multiple independent rice noodle placement spaces by several longitudinal partitions. The arrangement direction of the multiple rice noodle placement spaces is perpendicular to the direction of movement of the rice noodle frame 24. The cover 242 is hinged to the opening of the base frame 241 by a torsion spring 243. The torsion spring 243 allows the cover 242 to be tightly fastened to the opening of the base frame 241. The torsion spring 243 is located on the forward side of the rice noodle frame 24 in the upper section of the conveyor chain 23. Only the upper section of the conveyor chain 23 is equipped with a rack 27 and a pressure bar 28. The rack 27 and the pressure bar 28 are located below and above the pivot pin 244, respectively. The two ends of the pressure bar 28 are located outside the two ends of the conveyor chain 23 and are located between the two U-shaped support plates 25.

[0043] At both ends of the conveying device, a U-shaped support plate 25 is provided on the outer side of the rotating shaft 21. The two U-shaped support plates 25 are arranged with their openings facing each other. The width of the U-shaped support plate 25 is smaller than the gap between the two conveying chains 23. The U-shaped support plate 25 is fixed between the two conveying chains 23 by a connector. The U-shaped support plate 25 can limit whether the rice noodle frame 24 is flipped. The lower straight plates of the two U-shaped support plates 25 are connected by a connecting straight plate 26.

[0044] A lifting device 31 for the frame cover 242 is provided above the U-shaped support plate 25 on the feeding side of the conveying device, and a pulling device 32 for the frame cover 242 is provided below the U-shaped support plate 25 on the unloading side of the conveying device. Both the lifting device 31 and the pulling device 32 are composed of a tension cylinder arranged obliquely and a hook pull bar.

[0045] Operating principle:

[0046] The conveyor chain 23 rotates clockwise as shown in the diagram, moving the rice noodle frame 24 along the U-shaped support plate 25 to below the inlet 11. At this time, the rice noodle frame 24, located directly above the U-shaped support plate 25, is pulled open by the lifting device 31. The cut rice noodles are fed into the inlet 11 and placed in the rice noodle placement space of the bottom frame 241. The lifting device 31 releases the frame cover 242, which, under the action of the torsion spring 243, tightly locks the opening of the bottom frame 241. The conveyor chain 23 then moves the rice noodle frame 24 filled with rice noodles towards... When the rice noodle frame 24 moves to the right and is below the water cooling device and the cold air device 5, the rice noodle frame 24 rotates due to the meshing of the gears 245 and racks 27 on the pivot pins 244 on both sides of the rice noodle frame 24. During this process, cooling water falls from above onto the flipped rice noodle frame 24, and cooling air blows from above onto the rotating rice noodle frame 24. Both water cooling and air cooling processes can achieve direct cooling of all sides of the rice noodles, which has the advantage of uniform cooling of all parts of the rice noodles and can effectively improve the taste and quality of the rice noodles.

[0047] After the rice noodle frame 24 has cooled down, it moves with the conveyor chain 23 to the top of the discharge port 12. The pull-down device 32 pulls down and opens the cover 242 of the sealing frame 24 located directly below the U-shaped support plate 25, and the rice noodles fall from the discharge port 12 and are collected.

[0048] The empty rice noodle frame 24 continues to move via the conveyor chain 23. During this process, the rice noodle frame 24 moves along the U-shaped support plate 25 and the connecting straight plate 26, which can effectively ensure that the rice noodle frame 24 moves to the U-shaped support plate 25 below the feed inlet 11 with the opening facing upward, so as to ensure that the rice noodle frame 24 can be opened smoothly and loaded with rice noodles.

[0049] Water sprayed from the cooling device 4 is collected in the collection chamber 7 below. After being filtered, the water in the collection chamber 7 is pumped to the top nozzles for spraying.
