Description

Technical Field

[0001] The utility model belongs to the field of fermentation tank equipment, in particular to an inoculation port device of a fermentation tank. Background Art

[0002] The existing fermentation tank equipment is a closed container for cultivating the growth of microorganisms. It mainly includes a barrel-shaped sealed tank body with a stirring paddle inside and an air inlet at the bottom. The inoculation port is located at the upper head of the tank body. The pressure of the tank body needs to be released each time the inoculation port is used. First, the alcohol fire ring is ignited at the inoculation port, and then the seed liquid is poured into the fermentation tank. This inoculation method cannot keep the fermentation tank under positive pressure all the time. It needs to be operated under normal pressure, and there is a risk of infection due to operational errors during the inoculation process, which in turn affects the efficiency of inoculation and production quality.

[0003] Currently, no effective solution to the above problems has been found. Summary of the invention

[0004] The technical problem to be solved by the utility model is to propose an inoculation port device for a fermentation tank in view of the above shortcomings, which ensures the aseptic operation of inoculation, improves the problems of low inoculation efficiency and poor quality, improves the inoculation quality of the fermentation tank, and reduces production costs.

[0005] In order to solve the above technical problems, the utility model is a fermentation tank inoculation port device, comprising an inoculation port tube sealedly connected to the top of the fermentation tank, wherein the inoculation port tube is sealedly connected to an inoculation port cap.

[0006] Furthermore, the middle portion of the inoculation port tube is an arc-shaped tube, and an external thread is provided near the upper end of the arc-shaped tube.

[0007] Furthermore, the upper end of the inoculation port tube extends into the inoculation port cap, and the inoculation port cap is provided with an internal thread matching the external thread, and the inoculation port tube and the inoculation port cap are screwed together via the external thread and the internal thread.

[0008] Furthermore, an inoculation valve is provided in the middle of the inoculation port tube, and an exhaust valve is provided at the upper end of the inoculation port cap.

[0009] The utility model adopts the above technical solution, and has the following advantages compared with the prior art:

[0010] 1. The design of the fermentation tank inoculation port ensures the aseptic operation of inoculation and avoids the risk of contamination during the inoculation process.

[0011] 2. The fermentation tank inoculation port device improves the efficiency of inoculation, reduces production costs, and ensures the continuity and safety of production. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings. Those skilled in the art should understand that the following does not constitute a limitation on the protection scope of the utility model.

[0017] Examples, such as Figure 1-3 As shown, a fermentation tank inoculation port device includes an inoculation port tube 1 sealed and connected to the top of the fermentation tank 7, and the inoculation port tube 1 is sealed and connected to an inoculation port cap 2.

[0018] The middle part of the inoculation port tube 1 is an arc-shaped tube, and an external thread 5 is provided near the upper end of the arc-shaped tube.

[0019] The upper end of the inoculation port tube 1 extends into the inoculation port cap 2. The inoculation port cap 2 is provided with an internal thread 6 matching the external thread 5. The inoculation port tube 1 and the inoculation port cap 2 are screwed together via the external thread 5 and the internal thread 6. By rotating the thread, the inoculation port tube 1 and the inoculation port cap 2 can be tightly connected together to ensure their tightness and prevent material leakage. The threaded connection design facilitates the continuity and safety of the inoculation operation.

[0020] An inoculation valve 3 is provided in the middle of the inoculation port tube 1, and an exhaust valve 4 is provided at the upper end of the inoculation port cap 2. The fermentation tank 7 can be kept at a positive pressure by the inoculation valve 3 and the exhaust valve 4, which is convenient for the safety and continuity of the inoculation operation.

[0021] The specific operation process of this embodiment is as follows:

[0022] The inoculation port tube 1 and the inoculation port cap 2 are disinfected by air disinfection and actual disinfection. During this process, the inoculation valve 3 is kept in an open state, the exhaust valve 4 of the inoculation port cap 2 is kept in a slightly open state, and the fermentation tank 7 is kept in a positive pressure state. During inoculation, the inoculation valve 3 is closed, the exhaust valve 4 of the inoculation port cap 2 is opened, and when the inoculation port tube 1 and the inoculation port cap 2 are in a normal pressure state, the inoculation port cap 2 is unscrewed, and the inoculation port tube 1 is connected to the bacterial seed tank through a hose under an alcohol flame, and then the inoculation valve 3 is opened, and the bacterial seed is injected from the bacterial seed tank into the fermentation tank 7 by adjusting the pressure of the fermentation tank 7. After the inoculation is completed, the inoculation valve 3 is closed, and the connection between the inoculation port tube 1 and the bacterial seed tank through the hose is disconnected, and finally the inoculation port cap 2 is tightened to complete an inoculation operation.

[0023] The above is an example of the best implementation of the utility model, and the parts not described in detail are common knowledge of ordinary technicians in this field. The protection scope of the utility model is based on the content of the claims, and any equivalent transformation based on the technical inspiration of the utility model is also within the protection scope of the utility model.
