Description

Technical Field

[0001] The utility model relates to the field of food production, in particular to a needle tube for adding bacterial liquid and a bacterial liquid adding device. Background Art

[0002] In the ever-increasing consumption trend, consumers' demand for personalized and differentiated dairy products continues to increase, especially drinks with live bacteria (such as yogurt), which can balance intestinal flora and improve intestinal health, and gradually gain the favor of consumers. This has also become a new driving force and new direction for the development of liquid dairy products. However, before adding live bacteria, the following should be done: To ensure food safety, the sterility of the live bacteria must be ensured during the addition process; the uniformity and controllability of the live bacteria must be ensured during the addition process.

[0003] For the addition of bacterial liquid, the sterile syringe is the most important part of the sterile addition device or equipment, which includes the bacterial liquid input needle and the bacterial liquid output needle. The bacterial liquid input needle is used to connect to the bacterial bag, and the bacterial liquid output needle is used to connect to the main line of the production line. The bacterial liquid input needle and the bacterial liquid output needle are connected by a hose, so as to transport the bacterial liquid in the bacterial bag to the main line of the production line to achieve the addition of bacterial liquid. However, most of the sterile syringes on the market are single-input and single-output (that is, one bacterial liquid input needle corresponds to one bacterial liquid output needle), which can only be used to supply bacterial liquid to one main line, and cannot match production lines with high addition amounts and multiple pipelines, resulting in low production efficiency and incompatibility with production lines with high addition amounts.

[0004] Therefore, the inventor, relying on his many years of experience and practice in related industries, proposes a syringe and a bacteria liquid adding device for adding bacteria liquid to overcome the defects of the prior art. Utility Model Content

[0062] In the utility model, a first needle 1 is connected to a bacteria bag (not shown), and an adapter 3 is provided between the first needle 1 and a plurality of second needles 2. The input port of the adapter 3 is connected to the first needle 1, and the plurality of output ports of the adapter 3 are respectively connected to the plurality of second needles 2. The bacterial liquid input from the bacteria bag into the first needle 1 can be respectively transported to the plurality of second needles 2 through the adapter 3. Since the plurality of second needles 2 are respectively connected to corresponding production line pipelines (not shown), the bacterial liquid can be respectively output to the corresponding production line pipelines through the plurality of second needles 2, so as to realize the demand of supplying bacterial liquid to a plurality of main pipelines with a single bacteria bag at the same time, thereby meeting the production requirements of multiple pipelines and high addition amount, and effectively improving the production efficiency of live bacteria beverages.

[0063] In an optional embodiment of the present invention, Figure 1 , Figure 2 As shown, the first needle head 1 includes a first needle tube 101 and a first connecting section 105. The first needle tube 101 has a first tip 102 and a first connecting end 103 opposite to each other (the two ends of the first needle tube 101 are the first tip 102 and the first connecting end 103 respectively). The first tip 102 or the first needle tube 101 is provided with a first needle hole 104 connected to the inside of the first needle tube 101 at a position close to the first tip 102. The first connecting end 103 is connected to the first connecting section 105. During use, the first needle tube 101 is inserted into the fungus bag, so that it can be used to output the fungus liquid in the fungus bag to the outside.

The second connecting section 107 has a liquid outlet, and the first needle hole 104 and the liquid outlet are respectively connected to the first infusion channel. The bacterial liquid in the bacteria bag can enter the first infusion channel through the first needle hole 104, and then be output from the liquid outlet connected to the first infusion channel, so as to take out the bacterial liquid in the bacteria bag.

[0065] Further, such as Figure 2 As shown, a plurality of convex ribs 1061 are arranged on the outer wall of the first screwing section 106, and the plurality of convex ribs 1061 are spaced and evenly arranged along the circumference of the first screwing section 106. The arrangement of the first screwing section 106 facilitates the operation of rotating the first needle tube 101 into the fungus bag by the staff by screwing the first screwing section 106 during the process of inserting the first needle tube 101 into the fungus bag.

[0067] In this embodiment, if Figure 2 As shown, the diameter of the first sealing protruding ring 1071 gradually decreases from the direction close to the first screwing section 106 to the direction away from the first screwing section 106, so as to facilitate insertion into the first hose 4 and facilitate assembly and disassembly.

[0068] In an optional embodiment of the present invention, Figure 1 , Figure 3As shown, the second needle 2 includes a second needle tube 201 and a third connecting section 206.

The second screwing section 205 has a liquid inlet, and the second needle hole 204 and the liquid inlet are respectively connected to the second infusion channel. The bacterial liquid passes through the first infusion channel in the first needle 1 and the adapter 3 in turn, is diverted and enters the corresponding second infusion channel in the second needle 2, and is finally output to the production line pipeline through the second needle hole 204 for adding bacterial liquid to beverages.

[0070] Further, such as Figure 3 As shown, a plurality of screwing fins 207 are arranged on the outer wall of the second screwing section 205, and the plurality of screwing fins 207 are arranged at intervals along the circumference of the second screwing section 205. The setting of the second screwing section 205 facilitates the operation of the staff in the process of inserting the second needle tube 201 into the production line pipeline by screwing the second screwing section 205. During the screwing process, the staff can control the rotation and insertion of the second needle tube 201 by applying pressure to the screwing fins 207 with their fingers. Among them, the outer wall of the third connecting section 206 is provided with an external thread 2061 for matching with the internal thread on the production line pipeline, and the threaded connection between the second needle head 2 and the production line pipeline can be achieved by screwing.

A second sealing convex ring 2051 is provided at the liquid inlet of the second screwing section 205 or on the outer wall near the liquid inlet along the circumference of the second screwing section 205. The second sealing convex ring 2051 is inserted into the second hose 5 and is interference-connected with the inner wall of the second hose 5 to achieve a sealed connection effect, avoid leakage at the connection position between the second needle 2 and the second hose 5, and avoid contamination by the external environment, thereby ensuring a sterile environment for bacterial liquid transportation.

[0072] In this embodiment, if Figure 3 As shown, the diameter of the second sealing protruding ring 2051 gradually decreases from the direction close to the third connecting section 206 to the direction away from the third connecting section 206, so as to facilitate insertion into the second hose 5 and facilitate assembly and disassembly.

[0074] Further, such as Figure 1 , Figures 4 to 6 As shown, the curved pipe section 303 has a bending portion to achieve a 90° bend of the curved pipe section 303 between the inlet and the outlet, so as to bend at least a portion of the pipe section on the curved pipe section 303 close to its outlet to a position parallel to the second straight pipe section 302, thereby ensuring uniform and smooth passage of the second hose 5, and avoiding excessive bending of the second hose 5 connected to the curved pipe section 303 during the actual assembly process, which may cause the bacterial liquid to be unable to pass smoothly.

[0075] In this embodiment, if Figures 4 to 6As shown, a third sealing convex ring 3011 is provided at the inlet of the first straight pipe section 301 or on the outer wall near the inlet thereof along the circumference of the first straight pipe section 301.
