Description

Technical Field

[0001] This application relates to the field of rice wine production technology, specifically to a rice wine sampling device used in the fermentation and brewing process of rice wine. Background Technology

[0002] Rice wine is a traditional fermented wine, mainly made from glutinous rice or regular rice through fermentation. Its production process includes soaking, steaming, and fermentation. There are various brewing methods, including fermentation, distillation, and blending. Rice wine has a low alcohol content, a mellow taste, and is rich in carbohydrates, protein, B vitamins, and minerals.

[0003] An existing patent (publication number: CN220854298U) discloses a sampling device for rice wine during the fermentation process. It includes a sealing mechanism for sealing the fermentation tank. Inside the sealing mechanism is a clamping mechanism for holding the sealing cap of the fermentation tank. This mechanism works by compressing a corrugated sealing cover, placing the leather sealing cover over the top of the fermentation tank, and stretching the sealing strip to contract the leather sealing cover to achieve a seal. Then, rotating the clamping knob moves the clamping block towards the center to clamp the handle of the fermentation tank's sealing cap. A sampling connecting tube is then inserted through the extraction port. Raising the clamping knob extends the corrugated sealing cover, opening the fermentation tank's sealing cap. The sampling tube is then inserted into the fermentation tank to extract the sample. After extraction, the sampling tube is removed, the corrugated sealing cover is pressed down, and the clamping knob is rotated to release the fermentation tank's sealing cap, allowing the fermentation tank to remain sealed. This achieves the effect of reducing air contact with the rice wine during sampling.

[0004] The aforementioned rice wine sampling device involves multiple steps during sampling. Workers must attach the device to the fermentation tank, open and lift the tank's sealed lid, and then insert the sampling tube. This process is laborious and inefficient, indicating room for improvement. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a rice wine sampling device for the fermentation and brewing process of rice wine. This device simplifies the rice wine sampling process, saves manpower, and improves sampling efficiency. It also solves the problem that existing rice wine sampling devices involve many steps and are laborious to operate, leaving room for improvement.

[0006] To achieve the above objectives, this application provides the following technical solution: a sampling device for rice wine during the fermentation process of rice wine brewing, comprising a fermentation tank, a top cover at the top of the fermentation tank, a sampling tube at the top of the fermentation tank, the sampling tube comprising a first pipe, the outer circumferential surface of the first pipe being slidably inserted into the interior of the top cover, a fixed base being fixedly connected to the top of the first pipe, a second pipe being fixedly connected to the outer circumferential surface of the fixed base, an air bladder at the end of the second pipe away from the fixed base, an insert rod being slidably inserted into the interior of the fixed base, a sealing plug being fixedly connected to the bottom of the insert rod, a top plate being fixedly connected to the top of the insert rod, a first spring being fixedly connected between the fixed base and the top plate, a through hole being opened inside the second pipe, a sealing ring being slidably sleeved on the outer circumferential surface of the second pipe, a collar being fixedly sleeved on the outer circumferential surface of the second pipe, a second spring being fixedly connected between the sealing ring and the collar, a support plate being fixedly sleeved on the outer circumferential surface of the first pipe, and a positioning plate being threadedly connected to the outer circumferential surface of the first pipe.

[0007] The above solution addresses the issue that existing rice wine sampling devices involve numerous steps and are labor-intensive. By opening the sealing ring and pressing the air bladder, the gas inside the air bladder can be expelled through the through-hole. Pulling up the sealing ring causes the air bladder to rebound, allowing the rice wine to be extracted through the sampling tube into the air bladder. The sampling operation is then completed through the drain tube, simplifying the rice wine sampling process, saving manpower, and improving sampling efficiency.

[0008] Furthermore, the support plate is located above the top cover, and the positioning plate is located below the top cover.

[0009] The above scheme uses a support plate to support the sampling tube and a positioning plate to position the sampling tube, allowing it to be installed on the top cover, which facilitates the installation and removal of the sampling tube.

[0010] Furthermore, a sealing sheet is fixedly connected to the bottom surface of the support plate, and a sealing sheet is fixedly connected to the upper surface of the positioning plate.

[0011] Through the above scheme, the sealing plates at the bottom of the support plate and the top of the positioning plate can not only improve the sealing effect between the top cover and the sampling tube, but also increase the frictional resistance between the support plate and the positioning plate and the top cover, thereby improving the stability of the sampling device.

[0012] Furthermore, both the first and second pipes are transparent plastic pipes, and the airbag is made of transparent material.

[0013] The above scheme allows for easy observation of the rice wine sampling process through the transparent first and second pipes and airbag, facilitating the sampling operation.

[0014] Furthermore, a support rod is fixedly connected to the outer circumferential surface of the support plate, and the other end of the support rod away from the support plate is fixedly connected to the outer circumferential surface of the second pipe.

[0015] The above-mentioned scheme provides support for the second pipeline, thereby improving its stability and consequently enhancing the overall stability of the sampling tube and sampling device.

[0016] Furthermore, an installation tube is fixedly connected to the top of the airbag, and the inner wall of the installation tube is threadedly connected to the output end of the second pipe.

[0017] The above solution facilitates the installation and removal of the airbag by setting up the installation tube, which in turn facilitates the disassembly, cleaning, and maintenance of the airbag.

[0018] Furthermore, a fixing ring is fixedly fitted onto the outer circumferential surface of the second pipe, and a sealing sheet is fixedly connected to the bottom surface of the fixing ring.

[0019] With the above method, the installation pipe abuts against the sealing plate at the bottom of the fixing ring during installation, thereby improving the sealing effect between the installation pipe and the second pipe.

[0020] Furthermore, the bottom of the airbag is provided with a drain pipe, and the bottom of the drain pipe is threaded with a sealing cap.

[0021] Using the above method, the sealing cap can be opened, allowing the rice wine sample extracted from inside the airbag to flow out through the drain tube, thus completing the sampling operation.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This rice wine sampling device, used in the fermentation and brewing process, allows gas to escape through a through-hole when the sealing ring is opened and the air bladder is pressed. Pulling up the sealing ring causes the air bladder to rebound, allowing rice wine to be drawn through the sampling tube into the air bladder. The sampling is then completed through the drain pipe. This simplifies the rice wine sampling process, saves manpower, and improves sampling efficiency. The inclusion of a support plate and positioning plate facilitates the installation and disassembly of the sampling tube, enhancing the device's flexibility and practicality. It solves the problem of existing rice wine sampling devices having numerous steps and requiring considerable effort to operate. Attached Figure Description

[0033] Please see Figure 1 , Figure 2 and Figure 3 A sealing sheet is fixedly connected to the bottom surface of the support plate 5 and a sealing sheet is fixedly connected to the upper surface of the positioning plate 6. The sealing sheets at the bottom of the support plate 5 and the top of the positioning plate 6 can not only improve the sealing effect between the top cover 2 and the sampling tube 3, but also increase the frictional resistance between the support plate 5 and the positioning plate 6 and the top cover 2, thereby improving the stability of the sampling device.

[0034] Please see Figure 1 , Figure 2 and Figure 3 The first pipe 301 and the second pipe 303 are both transparent plastic pipes, and the airbag 4 is made of transparent material.

The installation tube 8 facilitates the installation and disassembly of the airbag 4, thereby facilitating the disassembly, cleaning, and maintenance of the airbag 4.

[0037] Please see Figure 2 and Figure 3 A fixing ring 312 is fixedly sleeved on the outer circumference of the second pipe 303. A sealing sheet is fixedly connected to the bottom surface of the fixing ring 312. When the installation pipe 8 is installed, it abuts against the sealing sheet at the bottom of the fixing ring 312, thereby improving the sealing effect between the installation pipe 8 and the second pipe 303.

[0038] Please see Figure 1 , Figure 2 and Figure 3The bottom of the airbag 4 is equipped with a drain pipe 9, and the bottom of the drain pipe 9 is threaded with a sealing cap 10. The sealing cap 10 can be opened to allow the rice wine sample extracted from the airbag 4 to flow out through the drain pipe 9, thus completing the sampling operation.

[0039] This embodiment provides a rice wine sampling device used in the fermentation process of rice wine brewing. By opening the sealing ring 309 and pressing the air bladder 4, the gas inside the air bladder 4 can be discharged through the through hole 308. By pulling up the sealing block 305, the air bladder 4 rebounds, allowing the rice wine to be extracted through the sampling tube 3 into the air bladder 4, and then the sampling operation is completed through the drain pipe 9. This simplifies the rice wine sampling process, saves manpower, and improves sampling efficiency. By setting up the support plate 5 and the positioning plate 6, the installation and disassembly of the sampling tube 3 are facilitated, improving the flexibility and practicality of the device. This solves the problem that existing rice wine sampling devices have many steps and are laborious to operate.

[0040] It should be noted that the outer circumferential surfaces of the positioning plate 6 and the sealing cover 10 are provided with anti-slip protrusions to facilitate the rotation of the positioning plate 6 and the sealing cover 10.

[0041] The working principle of the above embodiments is as follows:

[0042] An opening can be made inside the top cover 2, and then the sampling tube 3 can be inserted into the top cover 2. The sampling tube 3 is supported by the support plate 5, and then the positioning plate 6 is used to position the sampling tube 3 from the bottom of the top cover 2 to complete the installation of the sampling device. During the sampling operation, first push the sealing ring 309 towards the collar 310 to make the through hole 308 leak out. Then squeeze the airbag 4 to make the gas inside the airbag 4 escape through the through hole 308. Then release the sealing ring 309, and the sealing ring 309 will move back under the action of the second spring 311 to block the through hole 308 again. Finally, pull the top plate 306 to move the insertion rod 304 and the sealing plug 305 upward, so that the second pipe 30 3. Connect the first pipe 301, release the hand that squeezes the airbag 4, and the airbag 4 will rebound, drawing out the rice wine inside the fermentation tank 1 through the first pipe 301, the fixing seat 302 and the second pipe 303. The drawn rice wine will enter the airbag 4. Remove the sealing cap 10, and the rice wine inside the airbag 4 will be discharged through the drain pipe 9. Place a sampling container below the drain pipe 9 in advance so that the rice wine sample flows into the container, and the sampling operation can be completed. After the sampling is completed, release the top plate 306, and the sealing plug 305 will move back under the action of the first spring 307, cutting off the connection between the first pipe 301 and the second pipe 303 again, so that the fermentation tank 1 is always sealed.
