Description

Technical Field

[0001] This utility model relates to the field of sampling of hexanoic acid bacteria solution, and in particular to a sampling device for hexanoic acid bacteria solution. Background Technology

[0002] As one of the twelve major aroma types of Chinese baijiu, strong aroma baijiu is characterized by its rich cellar aroma, mellow sweetness, clean and refreshing taste, harmonious flavor, and pure taste, making it the most widely distributed and popular type of baijiu. Strong-aroma baijiu can be categorized by region into Sichuan-style, Jianghuai-style, and Northern-style baijiu; by raw materials into single-grain and multi-grain baijiu; and by production process into the original cellar method, the running cellar method, and the traditional five-still method. This demonstrates the complexity and unique appeal of the strong-aroma baijiu production process. However, one common thread is that its main aroma compound is ethyl hexanoate. Furthermore, the level of ethyl hexanoate is currently a relatively effective method for judging the quality of the raw spirit in strong-aroma baijiu. Therefore, most strong-aroma baijiu distilleries consider "increasing ethyl hexanoate" a primary task in their daily production. A crucial aspect of increasing ethyl hexanoate content is the preparation of hexanoic acid bacteria solution. Since hexanoic acid bacteria are anaerobic, sampling and analysis of the hexanoic acid bacteria solution are essential for better monitoring of the fermentation process.

[0003] Currently, hexanoic acid bacteria broth is obtained through deep static culture. During the culture process, sampling is usually done by shaking the Erlenmeyer flask before taking the sample. The purpose of shaking is to ensure uniformity in the upper, middle and lower layers, which can more accurately reflect the fermentation situation. However, the drawback is that the shaking process inevitably exposes the sample to air in the upper layer. How to achieve sampling of the upper, middle and lower layers of bacterial broth without shaking is the problem that this patent needs to overcome. Utility Model Content

[0004] The main purpose of this invention is to address the problems of uneven sampling and easy contact with air.

[0005] To address the above problems, this utility model proposes a sampling device for hexanoic acid bacteria solution, comprising:

[0006] Hollow outer cylinder;

[0007] A hollow inner cylinder, which is inserted into the interior of a hollow outer cylinder;

[0008] Multiple through holes are provided on one side of the hollow outer cylinder;

[0037] 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.

[0038] To achieve the above-mentioned utility model objectives, such as Figure 1-5 As shown, this utility model provides a sampling device for hexanoic acid bacteria liquid, including a hollow outer cylinder 4 and a hollow inner cylinder 3, wherein the hollow inner cylinder 3 is inserted into the interior of the hollow outer cylinder 4, a plurality of through holes 4 are provided on one side of the hollow outer cylinder 4, and a sampling groove 6 is provided on the outer side of the hollow inner cylinder 3.

[0039] In this embodiment, when it is necessary to sample the hexanoic acid bacteria solution, the hollow inner cylinder 3 can be rotated so that the sampling groove 6 of the hollow inner cylinder 3 corresponds to the through hole 4 of the hollow outer cylinder 4. Then, the hexanoic acid bacteria solution sampling device can be placed inside the hexanoic acid bacteria solution, so that the hexanoic acid bacteria solution can enter the interior of the hollow inner cylinder 3 through the connected through hole 4 and sampling groove 6. After sampling is completed, the hollow inner cylinder 3 can be rotated so that the through hole 4 and sampling groove 6 are misaligned, and then the hexanoic acid bacteria solution sampling device can be removed to complete the sampling.

[0040] Preferably, it has three through holes 4, which allows for the stratified sampling of the hexanoic acid bacteria solution in the upper, middle and lower layers.

[0041] Preferably, the hollow outer cylinder 4 and the hollow inner cylinder 3 are made of transparent acrylic material, which facilitates the observation of internal sampling.

[0042] like Figure 1 As shown, a connecting rod 2 is provided at the upper end of the hollow inner cylinder 3, and a handle 1 is provided at the upper end of the connecting rod 2. Thus, the connection rod 2 and the handle 1 make it easier to put in and take out the hexanoic acid bacteria liquid sampling device, and also make it easier to rotate and adjust the hollow inner cylinder 3.

[0043] As a further improvement, a threaded through hole is provided at the upper part of the outer circumference of the hollow outer cylinder 4. A fastening nut 8 is screwed into the threaded through hole. The fastening nut 8 can be screwed inward to abut against the hollow inner cylinder 3. In this way, by setting the fastening nut 8, the positions of the hollow inner cylinder 3 and the hollow outer cylinder 4 can be locked relative to each other after the position adjustment, so as to prevent the two from rotating during the sampling process.

[0044] As a further improvement, a rubber ring 7 is embedded on the outer side of the hollow inner cylinder 3 and around the sampling groove 6, and the rubber ring 7 protrudes from the outer surface of the hollow inner cylinder 3. In this way, after sampling is completed, the sampling groove 6 and the through hole 4 are misaligned and adjusted, and the rubber ring 7 can achieve a seal between the sampling groove 6 and the hollow outer cylinder 4, thereby preventing the leakage of hexanoic acid bacteria liquid sample from the gap between the two.

[0045] As one implementation method, such as Figure 1 As shown, connecting rod 2 is a solid cylindrical connecting rod.

[0046] As another implementation method, such as Figure 4 , 5 As shown, the connecting rod 2 is a hollow telescopic connecting rod, which includes an outer telescopic column 21, which is fixedly installed at the center of the upper end of the hollow inner cylinder. The outer telescopic column 21 has a square groove 26 inside, and the inner telescopic column 22 is slidably inserted into the groove 26 inside the outer telescopic column 21. The square slider 24 is fixedly installed at the lower end of the inner telescopic column 22. The square slider 24 and the inner telescopic column 22 have downward-facing accommodating chambers inside, and the spring 23 is installed inside the accommodating chamber. The top end of the spring 23 is fixedly connected to the top and bottom of the accommodating chamber, and the bottom end of the spring 23 is fixedly connected to the center of the top end of the hollow inner cylinder 3. The side of the outer telescopic column 21 has an elongated through hole, and an adjusting nut 25 is inserted into the elongated through hole. The square slider 24 has a threaded hole 27 corresponding to the position of the elongated through hole, and the inner side of the adjusting nut 25 is screwed into the threaded hole 27.

[0047] In this embodiment, when it is necessary to sample the hexanoic acid bacteria solution, the length of the connecting rod 2 can be adjusted. At this time, pull the handle 1 outward, and the spring 23 will push the inner telescopic rod 22 outward. At this time, the adjusting nut 25 will slide upward inside the elongated hole. After the length adjustment is completed, the adjusting nut 25 can be screwed inward. At this time, the adjusting nut 25 will be screwed into the threaded hole 27. Then the adjusting nut 25 will press the outer wall of the outer telescopic column 21, thereby locking the relative position of the outer telescopic column 21 and the inner telescopic column 22, thus completing the length adjustment of the connecting rod 2, and thus enabling the sampling of hexanoic acid bacteria solution at different depths.

[0048] Preferably, a rubber pad is fixedly provided on the outer wall of the outer telescopic column 21 and around the elongated through hole. In this way, the rubber pad can increase the friction between the adjusting nut 25 and the outer telescopic column 21, thereby preventing relative sliding between the adjusting nut 25 and the outer telescopic column 21 after locking.

[0049] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
