Abstract
Description
Technical Field
[0001] This utility model relates to the field of sampling technology, specifically to a sampling device for lactic acid bacteria products. Background Technology
[0002] Lactic acid bacteria products are usually cultured in sealed fermentation tanks. In order to detect the quality and content of lactic acid bacteria in lactic acid bacteria products, it is usually necessary to take some samples from the sealed tanks for testing periodically to ensure the normal cultivation of lactic acid bacteria products.
[0003] Traditional sampling methods for lactic acid bacteria products involve setting a sampling hole at the top of a sealed fermentation tank, and then taking a sample after opening the sealing cover of the sampling hole. However, during the sampling process, external air carrying microorganisms can flow into the sealed fermentation tank through the sampling hole, thus affecting the normal fermentation of lactic acid bacteria products. In addition, this sampling method is inconvenient to operate, inefficient, time-consuming, and causes excessive air to flow into the fermentation tank. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a sampling device for lactic acid bacteria products. By pressing the sampling bottle upward, the sampling needle pierces the rubber stopper and enters the fermentation tank for sampling, which can reduce the inflow of external air and is easy to operate.
[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: A sampling device for lactic acid bacteria products includes a fermenter and a sampling bottle. The sampling bottle includes a matching bottle body and a cap, as well as a rubber stopper, a sampling needle, and a sealing cap. A sampling hole is pre-drilled on the bottom wall of the fermenter body, and an interface is formed on the lower side. The sampling hole is located inside the interface. The rubber stopper is fixed to the inner wall of the interface and seals the sampling hole. The sampling needle is fixed to the cap. After the sampling needle pierces the rubber stopper, the lactic acid bacteria liquid in the fermenter flows into the sampling bottle along the sampling needle. After sampling, the sealing cap is installed in conjunction with the interface to seal the fermenter.
[0006] As an improvement, the sleeve is designed as a cylindrical tube, with the bottle cap movable inside the sleeve. A retaining edge is formed at the bottom of the sleeve to prevent the bottle cap from separating. Vertical through-grooves are formed on the side wall of the bottle cap, and a pair of them are mirrored on the left and right sides, which cooperate with a pair of ribs mirrored on the inner wall of the sleeve. The top of the sleeve is provided with the outlet of a sampling needle. When sampling, the sampling bottle is pushed to drive the sampling needle to pierce the rubber stopper to take a sample, reducing the inflow of external air during sampling and ensuring that the lactic acid bacteria can ferment and grow normally.
[0007] As an improvement, a spring is fitted between the bottle cap and the inner top wall of the sleeve. After sampling, the sampling needle will quickly retract into the sleeve under the force of the spring's rebound.
[0008] As an improvement, the sealing cap is a T-shaped cylinder, and the fine threaded section is fitted into the inside of the adapter to tighten the rubber stopper and seal the fermenter, so that the fermenter after sampling will not cause lactic acid bacteria leakage and can be stored better.
[0009] As an improvement, the top thread of the sleeve is fitted into the adapter and then tightened against the rubber stopper, which can prevent excessive waste of the lactic acid bacteria liquid that overflows during sampling.
[0010] The advantages of this utility model compared with the prior art are as follows: 1. This utility model uses a sampling needle to pierce the rubber stopper and enter the fermentation tank to sample lactic acid bacteria. During sampling, the inflow of external air is reduced, allowing the lactic acid bacteria to ferment and grow normally.
[0011] 2. The rubber stopper of this utility model is made of PFA material, which has good extensibility and shrinkage. After sampling, the rubber stopper can achieve self-sealing through its own shrinkage and sealing properties to prevent the sample from flowing out.
[0012] 3. The sampling operation of this utility model is simple and efficient. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.
[0022] like Figure 1 As shown, a sampling device for lactic acid bacteria products includes a fermentation tank 1 and a sampling bottle, such as... Figure 4 As shown, the sampling bottle includes a matching bottle body 2 and a bottle cap 3, and also includes a rubber stopper 8, a sampling needle 5, and a sealing cap 12; Figure 2 As shown, a sampling hole 9 is pre-drilled on the bottom wall of fermenter 1, and a connector 7 is formed on the lower side. The sampling hole 9 is located inside the connector 7. A rubber stopper 8 is fixed to the inner wall of the connector 7 and seals the sampling hole 9. A sampling needle 5 is fixed to the bottle cap 3. After the sampling needle 5 pierces the rubber stopper 8, the lactic acid bacteria liquid in fermenter 1 flows into the sampling bottle along the sampling needle 5. After sampling, as shown... Figure 5 As shown, the sealing cap 12 is fitted with the adapter 7 to seal the fermenter 1. The sampling needle 5 is located on the central axis of the cap 3, extends along the central axis of the cap 3 and penetrates the cap 3, communicating with the inside of the bottle body 2; the spring 6 surrounds the sampling needle 5, and the spring 6 is fitted between the cap 3 and the inner top wall of the sleeve 4.
[0023] like Figure 3 As shown, the sleeve 4 is a cylindrical design, the bottle cap 3 is movably installed inside the sleeve 4, the bottom of the sleeve 4 has a retaining edge to prevent the bottle cap 3 from separating, the side wall of the bottle cap 3 has a vertical through rib groove 10, a pair of which are mirrored on the left and right, and move in conjunction with a pair of ribs 11 mirrored on the inner wall of the sleeve 4; the top of the sleeve 4 is provided with the outlet of the sampling needle 5.
[0024] like Figure 6As shown, the sealing cap 12 is a T-shaped cylinder, and after the thin thread is fitted inside the adapter 7, it tightens the rubber stopper 8 to seal the fermenter 1. The top thread of the sleeve 4 is fitted inside the adapter 7, and then tightens the rubber stopper 8.
[0025] Among them, the rubber stopper 8 is made of PFA material. PFA material has good shrinkage and sealing properties. After sampling, the rubber stopper 8 can achieve self-sealing through the shrinkage and sealing properties of its own material.
[0026] In the specific implementation of this embodiment: During sampling, tighten the bottle body and the bottle cap thread inside the sleeve, then connect the top thread of the sleeve to the adapter at the bottom of the fermentation tank, and push the bottle body so that the top neck of the bottle body is pushed into the sleeve, which drives the sampling needle fixed on the bottle cap to pierce the rubber stopper and enter the fermentation tank. The lactic acid bacteria in the fermentation tank flow into the sampling bottle through the pierced sampling needle, thus completing the sampling.
[0027] After sampling, the sampling needle will quickly retract into the sleeve under the force of the spring rebound, tightening the sealing cap section with the threaded interface at the bottom of the fermenter.
