Description

Technical Field

[0001] This utility model relates to the technical field of sampling tools, specifically to a device for assisting sampling. Background Technology

[0002] In the brewing process of Maotai-flavor liquor, it is necessary to take samples of the mash at fixed times and locations to monitor the fermentation status of the mash in the fermentation pits. Currently, the brewing process of Maotai-flavor liquor often uses a method of sealing the fermentation pits with food-grade film and pit mud. If holes are made in the food-grade film for sampling, the holes will cause the pit mud to contaminate the mash.

[0003] To address this issue, existing technology proposes an auxiliary sampling device: A hollow tube is inserted into the fermentation pit during the initial filling process, with its bottom reaching the predetermined sampling position. Two semi-circular stainless steel plates are located at the bottom of the tube, automatically opening and closing via self-closing hinges. When sealing the pit, the upper end of the tube is sealed with a cap. During sampling, the cap is opened, and a sampler is inserted into the tube, pushing open the stainless steel plates at the lower end to allow sampling of the mash. After sampling, the sampler is removed, the stainless steel plates automatically close using the self-closing hinges, and the cap is then replaced.

[0004] However, in practical applications, it was found that as the fermentation process in the pit proceeds, the viscosity of the grains in the mash increases and the looseness decreases, which makes it impossible for the stainless steel plate to close smoothly. This causes the mash to seep into the inside of the pipe, affecting the accuracy of subsequent sampling. Utility Model Content

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this 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 this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] In the brewing process of Maotai-flavor liquor, in order to more accurately grasp the fermentation state of the mash in the fermentation pits and thus improve the production quality of liquor, it is necessary to systematically monitor the microbial community, temperature, humidity, acidity, reducing sugar content, moisture, starch, and other physicochemical indicators in the solid mash inside the fermentation pits. Simultaneously, it is also necessary to conduct timed, fixed-point, and location-specific sampling and analysis of the mash within the fermentation pits.

[0034] To address the difficulty of sampling the mash in fermentation pits, an auxiliary sampling device has been designed: a hollow tube is pre-inserted vertically into the pit when the mash is added, ensuring the lower end of the tube reaches the predetermined sampling depth. Two semi-circular stainless steel baffles are installed at the bottom of the tube, which open and close via self-closing hinges. During the pit sealing process, the upper end of the tube is sealed with a cover; when sampling is required, the cover is opened, and the sampler is lowered along the inside of the tube, pushing the baffles open to collect the sample from the mash. After sampling, the sampler is removed, the baffles automatically close via hinges, and the cover is then replaced to maintain the pit's airtightness.

[0035] However, in actual use, it was found that as the fermentation process progresses, the grains in the mash gradually become viscous and their structure becomes denser, causing the stainless steel baffle to be obstructed when closing and unable to close completely. This allows some mash to leak into the tube body, causing cross-contamination, which in turn affects the representativeness of subsequent sampling and the accuracy of test results. To solve this problem, this application was proposed, and the following detailed description is provided with reference to specific embodiments.

[0036] Example 1

[0037] This embodiment provides an auxiliary sampling device (hereinafter referred to as the device), which includes: a tube body 1 and a first sealing element 2;

[0038] The pipe body 1 has a first channel 11 and a second channel 12 that are interconnected and extend downward along its axial direction. A first sealing element 2 is installed in the second channel 12 and is used to seal the second channel 12. The length of the first sealing element 2 along the width direction of the pipe body 1 is less than the length of the first channel 11 along the width direction of the pipe body 1. Figure 1 In the diagram, the X-direction is the axial direction of the tube 1, and the Y-direction is the width direction of the tube 1.

[0039] The first seal 2 slides relative to the second channel 12. The first seal 2 is moved out of or into the second channel 12 under the action of an external force. When the first seal 2 slides into the first channel 11 under the action of an external force, a sampling path is formed between the first seal 2 and the first channel 11.

[0040] In the above technical solution, during sampling, the first sealing element 2 is moved to the first channel 11 using a tool. After sampling, the first sealing element 2 is moved to the second channel 12 using a tool. Under the action of external force, the first sealing element 2 can accurately return to the second channel 12 after each sampling, keeping the second channel 12 sealed and preventing the lees from seeping into the pipe body 1.

[0041] In one specific embodiment, the device further includes a second sealing element 3. In this embodiment, the second sealing element 3 is a cover, which is wrapped around and connected to the top end of the tube 1 to form a sealing structure. The cover and the end of the tube 1 are connected by threads (e.g., the cover has internal threads and the top end of the tube 1 has external threads), and a sealing ring is provided in the cover to achieve a seal between the cover and the end of the tube 1.

[0042] For ease of understanding, this embodiment uses the example of pipe 1 being vertically embedded in the fermented mash. The first sealing element 2 is located at the bottom end of pipe 1, and the second sealing element 3 is located at the top end of pipe 1. The method of using this device is as follows:

[0043] Before the mash is placed into the pit, the first sealing element 2 is installed inside the second channel 12 to seal the second channel 12 and keep the bottom of the pipe body 1 sealed. According to the three different depths inside the pit (upper, middle and lower layers), pipe bodies 1 of different lengths are selected and fixed on the fixed frame inside the pit. After the mash is placed into the pit, the pit is sealed with food film. After the food film covers the top of the pipe body 1, the second sealing element 3 is installed on the top of the pipe body 1 to keep the top of the pipe body 1 sealed.

[0044] When sampling the fermented mash, open the second seal 3 at the top of the tube body 1, make a hole in the food film at the top of the tube body 1, insert a tool (such as a four-cornered sleeve or long pliers) into the tube body 1, grasp the first seal 2 and move the first seal 2 out of the second channel 12 (to achieve communication between the second channel 12 and the outside of the tube body 1), move the first seal 2 into the first channel 11, so that the first seal 2, the first channel 11 and the second channel 12 are connected to form a path for the sampler to pass through. Through this path, the sampler passes through the first channel 11 and the second channel 12 to sample the fermented mash.

[0045] After sampling, the first seal 2 is inserted back into the second channel 12 using a tool to reseal the bottom of the tube 1. The second seal 3 is then reinstalled on the top of the tube 1 to maintain the seal at the top of the tube 1. The perforated food film is in a sealed environment formed by the second seal 3 and the top of the tube 1, thus preventing the pit mud from contaminating the mash.

[0046] In the above technical solution, by using the first sealing element 2 and the second sealing element 3 to seal both ends of the tube body 1, the tube body 1 is pre-embedded in the mash to prevent the mash from entering the tube body 1. During sampling, by opening and moving the first sealing element 2 and the second sealing element 3, the first sealing element 2, the first channel 11, and the second channel 12 form a path for the sampler to pass through, facilitating sampling. After sampling is completed, the first sealing element 2 and the second sealing element 3 are installed to reseal both ends of the tube body 1 to prevent the mash from being contaminated. It is worth mentioning that different tube body lengths can be set based on different sampling depth requirements.

[0047] The connection methods between the first seal 2 and the second channel 12 include, but are not limited to, the following two:

[0048] The first connection method is that the first sealing element 2 is an elastic element, and the outer wall of the first sealing element 2 and the inner wall of the second channel 12 are interference fit to achieve sealing of the second channel 12.

[0049] The second connection method is that the first sealing element 2 is provided with an external thread, and the second channel 12 is provided with an internal thread that connects with the external thread, and the first sealing element 2 and the second channel 12 are threadedly connected.

[0050] In a specific embodiment, such as Figure 1 and Figure 5 As shown, the first seal 2 has a protrusion 21 at one end near the first channel 11. The protrusion 21 is used to drive the first seal 2 to slide relative to the second channel 12 under the action of external force.

[0051] Example 2

[0052] This embodiment includes an auxiliary sampling device proposed in Embodiment 1, such as... Figure 1 and Figure 2 As shown, it further includes a fixing component 4 that is sleeved on the tube body 1 and used to fix the food film. A stop 5 is provided on the outer wall of the tube body 1, and the fixing component 4 abuts against the stop 5 and is limited by the stop 5.

[0053] In the above technical solution, the fixing component 4 further fixes the position of the food film to prevent the food film from shifting after the opening is made, thus preventing the opening from being outside the sealed space. The stop component 5 is used to stop and limit the fixing component 4, further preventing the food film from shifting position.

[0054] In a specific embodiment, such as Figure 3 and Figure 4 As shown, the fixing component 4 includes: a first chuck 41 that abuts against the stop member 5, and a second chuck 42 connected to the first chuck 41.

[0055] The first chuck 41 is provided with a snap-fit ​​part 43, and the second chuck 42 is provided with a mating part 44 corresponding to and connected to the snap-fit ​​part 43. In this embodiment, the snap-fit ​​part 43 is a buckle, and the mating part 44 is a through hole.

[0056] In the above technical solution, by covering the tube body 1 port and the first chuck 41 with a food film, and then connecting the first chuck 41 and the second chuck 42 using the engaging part 43 and the mating part 44, the position of the food film covering the tube body 1 port is limited between the first chuck 41 and the second chuck 42, thereby achieving further fixation of the food film. In this embodiment, utilizing the extensibility of the food film, the engaging part 43 connects to the mating part 44 without piercing the food film.

[0057] It is worth mentioning that, in other embodiments, if the operator pierces the food film with the snap-fit ​​part 43 and connects it with the mating part 44, a sealing head is installed at the end of the snap-fit ​​part 43, and a sealing environment is formed between the end of the snap-fit ​​part 43 and the sealing head, so as to seal the broken opening of the food film in the sealing environment and prevent the food film from leaking air.

[0058] It should be noted that in other embodiments, one or more sealing rings are provided between the first chuck 41 and the second chuck 42. The sealing rings are fitted onto the snap-fit ​​portion 43, and the top and bottom surfaces of the sealing rings abut against the second chuck 42 and the first chuck 41, respectively, so that there is no gap between the first chuck 41 and the second chuck 42, reducing the shaking of the second chuck 42 and further fixing the food film.

[0059] In a specific embodiment, such as Figure 2 and Figure 3 As shown, the latching part 43 includes a support part 431 and a guide part 432. One end of the support part 431 is connected to the first chuck 41 and the other end is connected to the guide part 432.

[0060] When the snap-fit ​​part 43 is connected to the mating part 44, the guide part 432 passes through the mating part 44 and the edge of the guide part 432 is snapped into place with the edge of the mating part 44 to achieve the mating connection between the snap-fit ​​part 43 and the mating part 44.

[0061] In the above technical solution, the connection between the guide part 432 and the mating part 44 simplifies the assembly or disassembly of the first chuck 41 and the second chuck 42, thereby improving efficiency.

[0062] In one specific embodiment, a support rod 45 is provided on the end of the first chuck 41 that is opposite to the second chuck 42, and the support rod 45 extends downward along the axial direction of the tube body 1.

[0063] In the above technical solution, the pipe body 1 is vertically fixed to a frame inside the fermentation pit during pre-embedding to maintain its positional stability. However, the length of the pipe body 1 varies, such as 0.5m, 3m, and 4m. For longer pipe bodies 1, there is a risk of tilting. Therefore, a support rod 45 is installed on the chuck, parallel to the pipe body 1. The support rod 45 and the pipe body 1 are buried together in the fermented mash. The presence of the support rod 45 improves the stability of the pipe body 1 within the fermented mash, preventing the sampling tube from tilting due to the collapse of the fermented mash during fermentation. It is worth noting that the number of support rods 45 is set based on requirements, such as 2, 3, or 4.

[0064] Example 3

[0065] This embodiment includes an auxiliary sampling device proposed in Embodiment 1 or Embodiment 2, and further, as... Figure 6 As shown, the first channel 11 is provided with a perforation 6, which is used to connect the outside world with the first channel 11, so that liquid substances can enter the first channel 11.

[0066] During the fermentation process, it is necessary to sample not only the solid matter (such as the fermented mash) but also the liquid matter. Therefore, in this embodiment, a perforation 6 is provided at the location of the first channel 11, through which the liquid matter in the fermented mash enters the first channel 11. Preferably, the perforation 6 is located in the middle of the first channel 11 or near the second sealing member 3 in the first channel 11.

[0067] During sampling, the second seal 3 is opened, the first seal 2 remains sealed with the second channel 12, and a tool (such as a disposable syringe) is inserted into the first channel 11 to sample the liquid substance.

[0068] It is worth mentioning that in this embodiment, temperature and humidity sensors, residual oxygen meters, solid-phase microextraction devices, etc. can be installed inside the tube 1 to achieve real-time monitoring of the fermentation process inside the liquor cellar.

[0069] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0070] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
