Technical Field
[0001] This utility model relates to the technical field of gas regulation devices, and in particular to a gas concentration balance regulation device for a fermentation process. Background Technology
[0002] Pickled vegetables are a traditional fermented food, widely popular in China and other East Asian countries. They are usually made from fresh vegetables such as cabbage, radish, and cucumber, which are pickled with salt and soaked in seasonings such as soy sauce. Through fermentation, pickled vegetables not only have a unique flavor but also increase their nutritional value and have a longer shelf life. During the fermentation process of pickled vegetables, the concentration of gas affects the speed and quality of fermentation. In order to ensure the stability of the fermentation process, a gas concentration balance control device is usually used.
[0003] Most existing gas concentration balance control devices in the fermentation process adopt a unidirectional stirring method, which prevents the pickled vegetables from getting effective and sufficient contact with various substances in the fermentation environment. This not only prolongs the overall fermentation cycle, but may also affect the uniformity of the fermentation process and the quality of the final product. Moreover, the sealing structure is poor and prone to leakage, which makes it impossible to maintain a stable gas concentration, thereby affecting the stability of the fermentation environment and product quality.
[0004] Therefore, those skilled in the art have provided a gas concentration balance control device for fermentation processes to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a gas concentration balance control device for the fermentation process. Through a stirring mechanism, a sealing mechanism, and an air pump, it achieves control and uniform stirring of gas concentration during the fermentation process, while preventing internal gas leakage.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A gas concentration balance control device for a fermentation process includes a base, two support columns fixedly mounted on the upper end of the base, a stirring mechanism inside one of the two support columns, the stirring mechanism including a rotating shaft, a spur gear fixedly mounted on one side of the rotating shaft, a third bevel gear fixedly mounted on the outer side of the rotating shaft near the spur gear, a first bevel gear sleeved on the outer side of the rotating shaft away from the spur gear, a fermentation cylinder fixedly mounted on one side of the first bevel gear, and an air pump fixedly mounted at the front end inside the other of the two support columns.
[0008] The front end of the fermentation tank is provided with a sealing mechanism, which includes a sealing cover and a feed inlet. A movable disc is slidably arranged inside the sealing cover. Multiple connecting ropes are fixedly arranged at the rear end of the movable disc, and a locking block is fixedly arranged at the rear end of each of the multiple connecting ropes.
[0009] Furthermore, a second bevel gear is rotatably provided at the front end of one of the two support columns, and the third bevel gear, the second bevel gear, and the first bevel gear are meshed together.
[0010] Furthermore, one side of the fermentation tank is rotatably positioned on the opposite side of the two support columns, and one side of the rotating shaft is rotatably positioned on one of the two support columns away from the air pump.
[0011] Furthermore, a motor is fixedly installed at the lower end of one of the two support columns, a turntable is fixedly installed at the output end of the motor, a connecting block is rotatably installed on one side of the turntable, a rack is rotatably installed at the upper end of the connecting block, and the rack is slidably installed at the front end of one of the two support columns, and the spur gear is meshed with the rack.
[0012] Furthermore, a plurality of first stirring blades are fixedly arranged on the side of the rotating shaft away from the spur gear, and a plurality of second stirring blades are rotatably arranged on the side of the plurality of first stirring blades away from the spur gear.
[0013] Furthermore, the rear end of the feed inlet is fixedly located at the front end of the fermentation tank, and two handles are fixedly located at the front end of the moving plate. The outer rear ends of the two handles are slidably located inside the front end of the sealing cover, and a sealing ring is fixedly located at the front end of the feed inlet.
[0014] Furthermore, the external parts of the multiple connecting ropes are slidably disposed inside the rear end of the sealing cover, the external parts of the multiple locking blocks are slidably disposed inside the rear end of the sealing cover, springs are fixedly disposed on opposite sides of each pair of locking blocks, and springs are fixedly disposed on opposite sides of each pair of springs inside the rear end of the sealing cover.
[0015] Furthermore, a hose is fixedly installed at the output end of the air pump, a control panel is fixedly installed at the front end of one of the two support columns, and a safety valve is fixedly installed at the rear end of the other of the two support columns.
[0016] This utility model has the following beneficial effects:
[0017] 1. The present invention proposes a gas concentration balance control device for fermentation process. When the motor is started, it will drive the turntable to rotate, causing the connecting block to drive the rack to reciprocate. The reciprocating motion of the rack will cause the spur gear to drive the rotating shaft to reciprocate, which in turn causes the first bevel gear and the third bevel gear to rotate. Since the second bevel gear and the first bevel gear will drive the fermentation cylinder to rotate between the support columns, the rotating shaft will drive the first stirring blade inside the fermentation cylinder to rotate. The rotation direction of the first stirring blade is opposite to the rotation direction of the fermentation cylinder, so that the pickled vegetables can be more thoroughly stirred and mixed inside the fermentation cylinder, thereby improving the stirring efficiency. The uniform stirring is conducive to the uniform distribution and growth metabolism of microorganisms in the pickled vegetables, which not only promotes the smooth progress of the fermentation process, but also shortens the fermentation cycle.
[0018] 2. The gas concentration balance control device for fermentation process proposed in this utility model, when the sealing cover is closed, first place the sealing cover on the feed inlet, and then push the sealing cover to move it towards the feed inlet, causing the locking block to slide in the opposite direction inside the sealing cover. When the sealing cover moves to the set position, the spring will push the locking block to move, causing the locking block to embed into the outside of the feed inlet, completing the connection between the sealing cover and the feed inlet. The whole operation process does not require complicated tools and too many steps, and is easy to operate. It provides a good seal to prevent gas leakage, which is conducive to the normal progress of the fermentation process of pickled vegetables and ensures the quality of fermented products.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Reference Figures 1-3 One embodiment provided by this utility model:
[0028] A gas concentration balance control device for a fermentation process includes a base 2. Two support columns 1 are fixedly mounted on the upper end of the base 2. A stirring mechanism 3 is installed inside one of the support columns 1. The stirring mechanism 3 includes a rotating shaft 304. A spur gear 305 is fixedly mounted on one side of the rotating shaft 304. A third bevel gear 312 is fixedly mounted on the outer side of the rotating shaft 304 near the spur gear 305. A first bevel gear 302 is sleeved on the outer side of the rotating shaft 304 away from the spur gear 305. A fermentation cylinder 301 is fixedly mounted on one side of the first bevel gear 302. A second bevel gear 309 is rotatably mounted at the front end of one of the two support columns 1. The third bevel gear 312, the second bevel gear 309, and the first bevel gear 302 are meshed and connected. The fermentation cylinder 301 is located on one side... The rotating shaft 304 is rotatably mounted on one side of the two support columns 1 opposite to each other. One side of the rotating shaft 304 is rotatably mounted on one of the two support columns 1 away from the air pump 7. A motor 308 is fixedly mounted inside the lower end of one of the two support columns 1. A turntable 307 is fixedly mounted at the output end of the motor 308. A connecting block 306 is rotatably mounted on one side of the turntable 307. A rack 303 is rotatably mounted on the upper end of the connecting block 306. The rack 303 is slidably mounted on the front end of the interior of one of the two support columns 1. A spur gear 305 meshes with the rack 303. Multiple first stirring blades 310 are fixedly mounted on the side of the rotating shaft 304 away from the spur gear 305. Multiple second stirring blades 311 are rotatably mounted on the side of the multiple first stirring blades 310 away from the spur gear 305.
[0029] Specifically, when stirring the pickled vegetables inside the fermentation tank 301, the motor 308 is started first, causing the turntable 307 at its output end to rotate. The rotation of the turntable 307 will drive the connecting block 306 to rotate synchronously, causing the rack 303 to slide stably back and forth inside the support column 1. Since the rack 303 is meshed with the spur gear 305, the sliding of the rack 303 will drive the spur gear 305 to rotate back and forth. The rotation of the spur gear 305 will drive the rotating shaft 304 to rotate. Since the first bevel gear 302 and the second bevel gear 309 are meshed, and the third bevel gear 312 and the second bevel gear 309 are meshed, when the rotating shaft 304 rotates... 4. During rotation, the first bevel gear 302 will drive the fermentation cylinder 301 to rotate. At the same time, the rotating shaft 304 will also drive the first stirring blade 310 installed inside the fermentation cylinder 301 to rotate. The rotation of the first stirring blade 310 will cause the second stirring blade 311 to passively rotate inside the fermentation cylinder 301, thereby further enhancing the stirring effect. The first stirring blade 310 and the fermentation cylinder 301 rotate in opposite directions. This reverse rotation stirring method can improve the uniformity of stirring and promote the gas generated during fermentation to be more evenly distributed around the pickled vegetables, which is conducive to the exchange of substances between the gas and the pickled vegetables, thereby ensuring the stable progress of the fermentation process.
[0030] Reference Figures 1-5 A sealing mechanism 4 is provided at the front end of the fermentation cylinder 301. The sealing mechanism 4 includes a sealing cover 402 and a feed inlet 408. A movable disk 403 is slidably arranged inside the sealing cover 402. Multiple connecting ropes 401 are fixedly arranged at the rear end of the movable disk 403. A locking block 404 is fixedly arranged at the rear end of each of the multiple connecting ropes 401. The rear end of the feed inlet 408 is fixedly arranged at the front end of the fermentation cylinder 301. Two handles 405 are fixedly arranged at the front end of the movable disk 403. The outer rear ends of the two handles 405 are slidably arranged inside the front end of the sealing cover 402. A sealing ring 406 is fixedly arranged at the front end of the feed inlet 408. The outer sides of the multiple connecting ropes 401 are slidably arranged inside the rear end of the sealing cover 402. The outer sides of the multiple locking blocks 404 are slidably arranged inside the rear end of the sealing cover 402. A spring 407 is fixedly arranged on each opposite side of each pair of locking blocks 404. The outer sides of each pair of springs 407 are fixedly arranged inside the rear end of the sealing cover 402.
[0031] Specifically, when it is necessary to activate and open the sealing cover 402, simply pull the handle 405, causing the connected movable disc 403 to slide forward inside the sealing cover 402. As the movable disc 403 slides, the connected rope 401 will be pulled accordingly, causing the locking block 404 to press against the spring 407 inside the sealing cover 402. The pressing of the locking block 404 will gradually release the locking state between the sealing cover 402 and the feed inlet 408, thus preparing for the subsequent opening operation. When the locking block 404 is released from the connection between it and the sealing cover 402, the sealing cover 402 can be removed for convenient feeding. During the closing process, simply cover the feed inlet 408 with the sealing cover 402 again and push it towards the feed inlet 408. When the sealing cover 402 moves, the locking block 404 inside the sealing cover 402 will be squeezed by the feed inlet 408, causing it to slide inside the sealing cover 402. When the sealing cover 402 moves to the preset locking position, the spring 407 inside the sealing cover 402 quickly rebounds, pushing the locking block 404 back to its original position, ensuring that it is tightly embedded in the external structure of the feed inlet 408. When the sealing cover 402 and the feed inlet 408 are connected, the sealing ring 406 between them is also squeezed, thus forming a tight and reliable sealing effect. The sealing cover 402 can be opened and closed by simply pulling the handle 405, which not only simplifies the operation process and improves work efficiency, but also facilitates feeding and discharging operations, thus providing a safer and more stable environment for the fermentation process of pickled vegetables.
[0032] Reference Figures 1-4 An air pump 7 is fixedly installed inside the front end of one of the two support columns 1, and a hose 6 is fixedly installed at the output end of the air pump 7. A control panel 5 is fixedly installed at the front end of one of the two support columns 1, and a safety valve 8 is fixedly installed inside the rear end of the other of the two support columns 1.
[0033] Specifically, when the concentration of fermentation gas inside the fermentation tank 301 is high, the air pump 7 inside the support column 1 will start, drawing the fermentation gas inside the fermentation tank 301 into the support column 1 through the hose 6, thereby maintaining the gas concentration inside the fermentation tank 301 within a suitable range. The control panel 5 makes the overall operation more convenient, and the safety valve 8 increases the safety of the fermentation process. When the gas inside the support column 1 is high, it will automatically release the pressure to prevent damage caused by excessive pressure.
[0034] Working principle: When stirring the pickled vegetables inside the fermentation tank 301, the motor 308 is activated, causing the turntable 307 to drive the connecting block 306 to rotate. The rotation of the connecting block 306 drives the rack 303 to slide back and forth inside the support column 1. Since the rack 303 meshes with the spur gear 305, the movement of the rack 303 drives the spur gear 305 to rotate back and forth. The rotation of the spur gear 305 drives the rotating shaft 304 to rotate. The first bevel gear 302 and the second bevel gear 304... 09 meshes, and the third bevel gear 312 meshes with the second bevel gear 309. When the rotating shaft 304 rotates, the first bevel gear 302 will drive the fermentation cylinder 301 to rotate. At the same time, the rotating shaft 304 will drive the first stirring blade 310 inside the fermentation cylinder 301 to rotate. The rotation of the first stirring blade 310 will cause the second stirring blade 311 to rotate. The rotation direction of the first stirring blade 310 and the fermentation cylinder 301 is always opposite, thereby achieving uniform stirring of the pickled vegetables, which is beneficial to the fermentation process.
[0035] Secondly, when it is necessary to open the sealing cover 402, pull the two handles 405. The handles 405 will drive the moving plate 403 to slide forward inside the sealing cover 402. The connecting rope 401 at the rear end of the moving plate 403 will be pulled as the moving plate 403 slides, causing the locking block 404 to compress the spring 407 under the pull of the connecting rope 401. This causes the locking block 404 to gradually release the lock on the feed port 408, and at the same time, it causes the sealing cover 402 to retract inside. Then, the sealing cover 402 can be opened to allow feeding. In operation, when the sealing cover 402 is closed, the sealing cover 402 is placed on the feed port 408 and then moved towards the feed port 408. At this time, the locking block 404 will be squeezed by the feed port 408, causing it to slide inside the sealing cover 402. When the sealing cover 402 moves to the set position, the spring 407 rebounds and pushes the locking block 404 to reset, so that it is embedded outside the feed port 408, causing the sealing ring 406 between the sealing cover 402 and the feed port 408 to be squeezed, thereby achieving a seal.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
