Description

Technical Field

[0001] This utility model belongs to the field of sampling tool technology, and in particular relates to a sampling tweezer for edible fungi liquid fermentation tank. Background Technology

[0002] In edible mushroom production, fermenters are used to cultivate liquid spawn. However, once the liquid spawn has reached a suitable stage, it needs to be sampled and tested to ensure it is up to standard before use. Therefore, aseptic techniques are typically used during sampling, usually with flame protection. Because the flame is located below the sampling valve, the operator's hands cannot be exposed to high temperatures for extended periods during sampling, which could easily burn the operator's hands and cause sample contamination, making it impossible to determine the quality of the liquid spawn. Therefore, a sampling tool that can prevent sample contamination and hand burns is needed.

[0003] Patent document CN104789463A discloses a bacterial growth sampling tool, including a semi-circular sampling end and a handle connected thereto, as well as an anti-slip hook fixedly connected to the handle. However, this tool is suitable for applications such as microbial amplification culture, but not for completing the opening and closing of the sampling valve. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a sampling tweezer for edible fungi liquid fermentation tanks.

[0005] This utility model is achieved through the following technical solution.

[0006] This utility model provides a sampling tweezer for edible fungi liquid fermentation tank, including a tweezer handle, a first tweezer body, a first tweezer arm, a second tweezer body, and a second tweezer arm. One end of the first tweezer body is connected to the tweezer handle, and the other end of the first tweezer body is connected to the first tweezer arm. One end of the second tweezer body is connected to the tweezer handle, and the other end of the second tweezer body is connected to the second tweezer arm. Fixing components are respectively provided on the first tweezer body and the second tweezer body.

[0007] Preferably, a protective cover is provided at one end of the fixing member.

[0008] Preferably, the fixing elements on the first and second tweezers are arranged asymmetrically.

[0009] Preferably, the first and second tweezer arms are bent at 25-35 degrees.

[0010] Preferably, the length of the tweezers is no more than 40cm.

[0011] Preferably, the bottom surface of the fixing member is lower than the bottom surfaces of the first and second tweezers.

[0012] Preferably, the length of the first tweezers body is greater than the length of the first tweezers arm.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention, through the setting of a fixing component, enables the simultaneous clamping and opening / closing of the sampling valve during the sampling process. The sampling valve does not need to be turned directly by hand, avoiding the risk of hand burns from flames and reducing the difficulty of sampling operations. The operator's hands do not approach the sampling tube opening, reducing the risk of liquid infection. Attached Figure Description

[0019] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0020] Example:

[0021] like Figures 1 to 3 As shown, a sampling tweezer for a liquid fermentation tank of edible fungi is made of stainless steel and includes a tweezer handle 1, a first tweezer body 2, a first tweezer arm 3, a second tweezer body 4, and a second tweezer arm 5. One end of the first tweezer body 2 is connected to the tweezer handle 1, and the other end of the first tweezer body 2 is connected to the first tweezer arm 3. One end of the second tweezer body 4 is connected to the tweezer handle 1, and the other end of the second tweezer body 4 is connected to the second tweezer arm 5. Fixing members 6 are respectively provided on the first tweezer body 2 and the second tweezer body 4.

[0022] A protective cover 7 is provided at one end of the fixing member 6. The protective cover 7 is detachable from the fixing member 6 and is used to prevent the fixing member 6 from puncturing the sampling bottle.

[0023] The fixing members 6 on the first tweezers body 2 and the second tweezers body 4 are arranged asymmetrically.

[0024] The first tweezers arm 3 and the second tweezers arm 5 are bent at 25-35 degrees. The first tweezers arm 3 and the second tweezers arm 5 are used to hold the alcohol cotton. The bent setting allows the alcohol cotton to be closer to the mouth of the sampling bottle than the straight tweezers arm.

[0025] The tweezers are no longer than 40cm, making them easy to use with one hand.

[0026] The bottom surface of the fixing member 6 is lower than the bottom surfaces of the first tweezers body 2 and the second tweezers body 4, so that the fixing member 6 can rotate the sampling valve 8.

[0027] The length of the first tweezer body 2 is greater than the length of the first tweezer arm 3, and the length of the second tweezer body 4 is greater than the length of the second tweezer arm 5, so that there is enough space for the fixing member 6 to rotate the sampling valve 8 to both sides.

[0028] The steps for sampling from a fermenter using the tweezers described in this application are as follows:

[0029] S1: Disinfect hands with alcohol (75% alcohol) and spray the surrounding environment with alcohol (75%) for disinfection.

[0030] S2: Use the tweezers of this application to remove the cotton plug at the mouth of the sampling tube 9, and inject alcohol and burn it with a flame gun;

[0031] S3: Place the prepared alcohol swab (95% alcohol swab) below the opening of the sampling tube 9;

[0032] S4: First, release some liquid from the inside of the sampling tube 9 near the opening, and then take a sample using a sterilized sampling bottle.

[0033] S5: First, use the first tweezers arm 3 and the second tweezers arm 5 to clamp the cotton plug of the sampling bottle and pull it out. During this process, the cotton plug should not be more than 1 cm away from the flame. Use the fixing part 6 on the second tweezers body 4 to rotate and open the sampling valve 8 so that the liquid can flow from the sampling tube 9 into the sampling bottle.

[0034] S6: After taking the sample, use the fixing part 6 on the first tweezers body 2 to rotate and close the sampling valve 9, and then insert the cotton plug into the mouth of the sampling bottle. During this period, the bottle mouth and the cotton plug must not leave the flame to complete the sampling.

[0035] The sampling tube 9 is connected to the fermentation tank storing the liquid seed, and the handle of the sampling valve 8 passes between the first tweezer arm 3 and the second tweezer arm 5 during sampling.
