Description

Technical Field

[0001] The invention relates to the technical field of persimmon vinegar inspection, in particular to a persimmon vinegar inspection sampler capable of ensuring sealing. Background Art

[0002] Persimmon vinegar is an acidic condiment made primarily from persimmons through fermentation and other processes. It combines the unique flavor of persimmons with the tart aroma of vinegar, holding a unique position in the food industry. Under suitable temperature and conditions, yeast converts the sugars in the persimmons into alcohol. This is like transforming the persimmon's "sweet energy" into a substance with a wine-like flavor, providing the foundation for acetic acid fermentation. Acetic acid bacteria then oxidize the alcohol into acetic acid. Acetic acid bacteria act like a "magic converter," transforming alcohol into the sour acetic acid, ultimately creating persimmon vinegar. During the fermentation process, sampling and testing can monitor various indicators of the fermentation broth, such as acidity, sugar content, and alcohol content, in real time. Changes in these indicators reflect the progress and effectiveness of fermentation. For example, by monitoring changes in acidity, we can understand the fermentation activity of acetic acid bacteria and determine whether fermentation is proceeding smoothly. If acidity increases slowly or stagnates, it may indicate unsuitable fermentation conditions or insufficient acetic acid bacteria activity, necessitating timely adjustments to process parameters such as temperature and ventilation.

[0003] When sampling persimmon vinegar in a fermentation tank, the tank lid needs to be opened and a portion of the persimmon vinegar needs to be taken out for inspection. However, after the tank lid is opened, the persimmon vinegar in the fermentation tank comes into contact with air, which affects the fermentation process. In addition, the taken-out persimmon vinegar is also easily exposed to air and reacts, which affects the accuracy of the inspection. Therefore, a persimmon vinegar inspection sampler that can ensure sealing is proposed. Summary of the Invention

[0004] The present invention aims to solve the shortcomings of the prior art in that after the tank lid is opened, the persimmon vinegar in the fermentation tank comes into contact with the air, thereby affecting the fermentation process, and the persimmon vinegar taken out is also easily exposed to the air and reacts, thereby affecting the accuracy of the inspection work. A persimmon vinegar inspection sampler that can ensure sealing is proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] The invention relates to a persimmon vinegar inspection sampler capable of ensuring sealing, comprising a fermentation tank and a sampling tube, characterized in that a circular groove is provided on the upper portion of the fermentation tank, an air bag is installed on the inner side of the circular groove, and a sealed sampling assembly is provided on the fermentation tank, wherein the sealed sampling assembly comprises a transmission unit provided on the fermentation tank, a second baffle rotatably connected to the inner side of the fermentation tank, a first baffle slidably provided on the upper portion of the fermentation tank, a rubber wheel rotatably connected to the upper portion of the fermentation tank, and a plurality of fan blades rotatably connected to the inner side of the fermentation tank, the first baffle is slidably provided on the upper portion of the fermentation tank, the circular groove is exposed by sliding, the sampling tube is inserted into the circular groove and automatically drives the second baffle to rotate to open the circular groove, and the sampling tube is moved downward, and the rubber wheel is driven to rotate when the sampling tube moves downward, and the plurality of fan blades are driven to rotate by the transmission unit when the rubber wheel rotates, and the wind force generated by the rotation of the fan blades forms a wind curtain at the circular groove, which can prevent outside air from entering the fermentation tank and also prevent the gas and liquid in the fermentation tank from escaping, thereby further ensuring the sealing of the fermentation tank during the sampling process.

[0007] A plurality of storage slots are provided on the inner side of the sampling tube, a plurality of sampling slots are provided on the side of the sampling tube, and an automatic opening and closing component is provided on the sampling tube, and the automatic opening component includes a third baffle slidably provided on the inner side of the sampling slot, a movable rod commonly installed on the plurality of sampling slots, and an L-shaped plate installed on the side of the movable rod. The L-shaped plate is movably connected to the sampling tube. After the sampling tube is inserted into the fermentation tank, the L-shaped plate squeezes the top of the fermentation tank and drives the third baffle to move up to expose the sampling slot through the movable rod. When the sampling tube is moved up after sampling, the L-shaped plate no longer squeezes the fermentation tank, and the third baffle resets to block the sampling slot, and the automatic reset and sealing design ensures that the sampling tube can maintain a sealed state for the persimmon vinegar after the sampling is completed, thereby preventing the sample from contacting the air and affecting the accuracy of the inspection work.

[0008] The above technical solution further includes:

[0009] A first sliding groove is provided on the upper part of the fermentation tank, and a sliding block is slidingly provided on the inner side of the first sliding groove. The sliding block is fixedly connected to the first baffle. A first spring is installed on the side of the sliding block. The end of the first spring away from the sliding block is fixedly connected to the inner wall of the first sliding groove, and the first baffle slides along the first sliding groove through the sliding block.

[0011] The transmission unit includes an open slot installed inside the fermentation tank, the inside of the open slot is respectively connected to a first gear and a second gear, the first gear and the second gear are meshed with each other, the inside of the open slot is connected to a plurality of third gears, the third gear and the second gear are meshed with each other, and the fan blade is installed on the side of the third gear.

[0012] The inner side of the fermentation tank is rotatably connected to a third rotating rod, and the third rotating rod is fixedly connected to the first gear. The upper part of the fermentation tank is rotatably connected to a second rotating rod, and a transmission belt is commonly provided between the second rotating rod and the third rotating rod. The rotation of the second rotating rod drives the third rotating rod to rotate through the transmission belt.

[0013] The upper part of the fermentation tank is rotatably connected to a second support plate, and the side of the second support plate is rotatably connected to a rubber wheel. A second bevel gear is installed at one end of the rubber wheel away from the second support plate, and a first bevel gear is installed at the end of the second rotating rod. The first bevel gear and the second bevel gear are meshed with each other. When the rubber wheel rotates, the second rotating rod is driven to rotate through the second bevel gear and the first bevel gear.

[0014] The rubber wheel is located on the movement track of the circular groove.

[0015] The sizes of the circular groove and the air bag opening are adapted to the size of the sampling tube.

[0016] A second sliding groove is provided on the side of the sampling tube, and the second sliding groove is slidably connected to the L-shaped plate. A third support plate is installed on the side of the sampling tube, and a telescopic rod is installed on the upper part of the third support plate. The end of the telescopic rod away from the third support plate is fixedly connected to the L-shaped plate. After the telescopic rod is reset, it drives the L-shaped plate and the movable rod to move downward, and the third baffle automatically moves downward and blocks the sampling slot.

[0017] The third baffle is tightly fitted to the inner wall of the sampling trough.

[0018] The present invention has the following beneficial effects:

[0019] 1. In the present invention, a sealed sampling assembly is provided. During the sampling preparation stage, the circular groove is exposed by sliding the first baffle so that the sampling tube can be inserted. The second baffle blocks the circular groove through the inner side of the fermenter, ensuring that the fermenter as a whole remains sealed, preventing the possibility of outside air entering the fermenter, and avoiding sealing loopholes caused by the early preparation of the sampling operation. During the process of the sampling tube moving downward for sampling, multiple fan blades rotate at the circular groove to generate an air curtain. The formation of the air curtain is like an invisible barrier, which can prevent outside air from entering the fermenter and also prevent the gas and liquid in the fermenter from escaping, further ensuring the sealing of the fermenter during the sampling process.

[0020] 2. In the present invention, by providing an automatic opening and closing component, when the sampling tube needs to be moved upward, the squeezing force of the L-shaped plate on the fermentation tank is released, and the L-shaped plate and the movable rod are simultaneously driven downward, so that the third baffle automatically moves downward and blocks the sampling slot, thereby performing an automatic reset and sealing design, ensuring that the sampling tube can remain sealed to the persimmon vinegar after sampling is completed, avoiding contact between the sample and the air and affecting the accuracy of the inspection work.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example 1

[0032] like Figure 1 - Figure 8 As shown, the present invention proposes a persimmon vinegar inspection sampler that can ensure sealing, including a fermentation tank 1 and a sampling tube 12, a circular groove 2 is opened on the upper part of the fermentation tank 1, an air bag 3 is installed on the inner side of the circular groove 2, and a sealed sampling assembly is provided on the fermentation tank 1. The sealed sampling assembly includes a transmission unit provided on the fermentation tank 1, a second baffle 11 rotatably connected to the inner side of the fermentation tank 1, a first baffle 7 slidingly provided on the upper part of the fermentation tank 1, a rubber wheel 32 rotatably connected to the upper part of the fermentation tank 1, and a plurality of fans rotatably connected to the inner side of the fermentation tank 1. Blade 17, slide the first baffle 7 to expose the circular groove 2, insert the sampling tube 12 into the circular groove 2 and automatically push the second baffle 11 to rotate to open the circular groove 2, and move the sampling tube 12 downward. When the sampling tube 12 moves downward, it drives the rubber wheel 32 to rotate. When the rubber wheel 32 rotates, it drives multiple fan blades 17 to rotate through the transmission unit. The wind force generated by the rotation of the fan blades 17 forms a wind curtain at the circular groove 2, which can prevent outside air from entering the fermentation tank, and also prevent the gas and liquid in the fermentation tank from escaping, further ensuring the sealing of the fermentation tank during the sampling process.

[0033] A plurality of storage slots 24 are provided on the inner side of the sampling tube 12, and a plurality of sampling slots 25 are provided on the side of the sampling tube 12. An automatic opening and closing component is provided on the sampling tube 12, and the automatic opening component includes a third baffle 26 slidingly arranged on the inner side of the sampling slot 25, a movable rod 27 installed together on the plurality of sampling slots 25, and an L-shaped plate 29 installed on the side of the movable rod 27. The L-shaped plate 29 is movably connected to the sampling tube 12. After the sampling tube 12 is inserted into the fermentation tank 1, the L-shaped plate 29 squeezes the top of the fermentation tank 1 and drives the third baffle 26 to move up through the movable rod 27 to expose the sampling slot 25. When the sampling tube 12 is moved up after sampling, the L-shaped plate 29 no longer squeezes the fermentation tank 1, and the third baffle 26 resets to block the sampling slot 25, and the automatic reset sealing design ensures that the sampling tube 12 can maintain a sealed state for the persimmon vinegar after the sampling is completed, thereby preventing the sample from contacting with the air and affecting the accuracy of the inspection work.

[0034] A first sliding groove 4 is provided on the upper part of the fermentation tank 1, and a sliding block 5 is slidingly provided on the inner side of the first sliding groove 4. The sliding block 5 is fixedly connected to the first baffle 7. A first spring 6 is installed on the side of the sliding block 5. The end of the first spring 6 away from the sliding block 5 is fixedly connected to the inner wall of the first sliding groove 4. The first baffle 7 slides along the first sliding groove 4 through the sliding block 5.

[0035] A first support plate 8 is installed on the inner side of the fermentation tank 1, and the side of the first support plate 8 is rotatably connected to the first rotating rod 9. The second baffle 11 is installed on the end of the first rotating rod 9 away from the first support plate 8. A torsion spring 10 is installed on the side of the second baffle 11 close to the first support plate 8. The end of the torsion spring 10 away from the second baffle 11 is fixedly connected to the first support plate 8, and the second baffle 11 rotates around the first rotating rod 9.

[0036] The transmission unit includes an open groove 13 installed on the inner side of the fermentation tank 1, and the inner side of the open groove 13 is respectively rotatably connected to the first gear 14 and the second gear 15, and the first gear 14 and the second gear 15 are engaged with each other. The inner side of the open groove 13 is rotatably connected to a plurality of third gears 16, and the third gear 16 is engaged with the second gear 15, and the fan blade 17 is installed on the side of the third gear 16.

[0037] The inner side of the fermentation tank 1 is rotatably connected to a third rotating rod 18, which is fixedly connected to the first gear 14. The upper part of the fermentation tank 1 is rotatably connected to a second rotating rod 20, and a transmission belt 19 is commonly provided between the second rotating rod 20 and the third rotating rod 18. The rotation of the second rotating rod 20 drives the third rotating rod 18 to rotate through the transmission belt 19.

[0038] The upper part of the fermentation tank 1 is rotatably connected to the second support plate 22, and the side of the second support plate 22 is rotatably connected to the rubber wheel 32. The end of the rubber wheel 32 away from the second support plate 22 is installed with a second bevel gear 23, and the end of the second rotating rod 20 is installed with a first bevel gear 21. The first bevel gear 21 is meshed with the second bevel gear 23. When the rubber wheel 32 rotates, the second rotating rod 20 is driven to rotate through the second bevel gear 23 and the first bevel gear 21.

[0039] The rubber wheel 32 is located on the movement track of the circular groove 2 .

[0040] The sizes of the circular groove 2 and the opening of the air bag 3 are adapted to the size of the sampling tube 12 .

[0041] In this embodiment, when it is necessary to sample the persimmon vinegar in the fermentation tank 1, the first baffle 7 can be slid so that the first baffle 7 slides along the first sliding groove 4 through the sliding block 5. At this time, the first spring 6 contracts until the circular groove 2 is exposed. At this time, the circular groove 2 is blocked by the second baffle 11 inside the fermentation tank 1, so that the fermentation tank 1 continues to maintain a sealed state. At this time, the sampling tube 12 is inserted into the circular groove 2. At the same time, the air bag 3 is tightly fitted with the sampling tube 12. At this time, the circular groove 2 is blocked by the sampling tube 12, so that the sampling tube 12 moves downward. When the sampling tube 12 moves downward, it can push the second baffle 11, so that the second baffle 11 rotates around the first rotating rod 9. At this time, the torsion spring 10 contracts until the opening of the circular groove 2 on the inside of the fermentation tank 1 is exposed, and then continues. The sampling tube 12 is moved downward so that the sampling tube 12 contacts the inner bottom of the fermentation tank 1 for sampling. When the sampling tube 12 is moved downward, the protruding part of the rubber wheel 32 can be squeezed, thereby driving the rubber wheel 32 to rotate. Since the second bevel gear 23 is meshed with the first bevel gear 21, when the rubber wheel 32 rotates, it can drive the second rotating rod 20 to rotate, and at the same time drive the third rotating rod 18 to rotate through the transmission belt 19. When the third rotating rod 18 rotates, it drives the first gear 14 to rotate. Since the first gear 14 and the third gear 16 are both meshed with the second gear 15, when the first gear 14 rotates, it can drive the third gear 16 to rotate through the second gear 15, and drive the fan blades 17 to rotate to generate wind force. The wind force generated by the rotation of multiple fan blades 17 at the circular groove 2 forms a wind curtain.

[0042] Example 2

[0043] like Figure 1 - Figure 8 As shown, based on the first embodiment, a second sliding groove 28 is opened on the side of the sampling tube 12, and the second sliding groove 28 is slidably connected to the L-shaped plate 29. A third support plate 30 is installed on the side of the sampling tube 12, and a telescopic rod 31 is installed on the upper part of the third support plate 30. The end of the telescopic rod 31 away from the third support plate 30 is fixedly connected to the L-shaped plate 29. After the telescopic rod 31 is reset, it drives the L-shaped plate 29 and the movable rod 27 to move downward, and the third baffle 26 automatically moves downward and blocks the sampling slot 25.

[0044] The third baffle 26 is in close contact with the inner wall of the sampling tank 25 .

[0045] In this embodiment, when the sampling tube 12 is inserted into the fermentation tank 1, the L-shaped plate 29 squeezes the fermentation tank 1, so that the L-shaped plate 29 moves up along the second sliding groove 28. At this time, the telescopic rod 31 is stretched and drives the movable rod 27 to move up. After the movable rod 27 moves up, it can drive multiple third baffles 26 to move up, thereby exposing the sampling slot 25. At this time, the persimmon vinegar can enter the storage slot 24 through the sampling slot 25 to complete the sampling work. When the sampling tube 12 needs to be moved up, the force of the L-shaped plate 29 squeezing the fermentation tank 1 is released, the telescopic rod 31 is reset, and at the same time drives the L-shaped plate 29 and the movable rod 27 to move down, so that the third baffle 26 automatically moves down and blocks the sampling slot 25.

[0046] 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.
