DETAILED DESCRIPTION
[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0016] A pressure control system for a fermentation tank used in edible vinegar production includes a pressure control box 1. An air pump 2 is installed at the top of the pressure control box 1. The air outlet of the air pump 2 is connected to the top of a fermentation tank 3 via a pipeline. A through-slot 4 is opened at the bottom of the pressure control box 1. The top of the fermentation tank 3 is connected to the top of a vinegar storage tank 22 via a pipeline. A venting electronic valve 5 is installed on the pipeline connecting the top of the fermentation tank 3 and the bottom of the vinegar storage tank 22. One end of a discharge pipe 6 is connected to the bottom of the fermentation tank 3, and the other end of the discharge pipe 6 is connected to the top of the vinegar storage tank 22. A discharge electronic pump 7 and a discharge electronic valve 8 are installed on the discharge pipe 6. An electronic pressure gauge 9 connected to the interior of the fermentation tank 3 is installed on the fermentation tank 3. A control panel 10 is installed on the pressure control box 1. The control panel 10 is electrically connected to the air pump 2. The control panel 10 can wirelessly transmit signals to and control the opening and closing of the venting electronic valve 5, the discharge electronic pump 7, and the discharge electronic valve 8. In use, this invention allows the user to input a predetermined air pressure value inside the fermentation tank 3 via the control panel 10. Then, the air pump 2 is activated to continuously pump air into the fermentation tank 3. The control panel 10 receives signals from the electronic pressure gauge 9 in real time to monitor air pressure changes inside the fermentation tank 3. When the air pressure inside the fermentation tank 3 reaches a specified value, the control panel 10 sends a wireless signal to control the opening of the venting electronic valve 5 to release air and continuously pump air in to ensure pressure balance. This ensures the oxygen content inside the fermentation tank 3 and the growth efficiency of acetic acid bacteria. The control panel 10 also controls the opening and closing of the venting electronic valve 5 based on the real-time air pressure changes inside the fermentation tank 3, ensuring the air pressure inside the fermentation tank 3 remains stable around the predetermined value, thus ensuring the growth efficiency of acetic acid bacteria, improving alcohol conversion rate, and increasing production efficiency.
[0017] Specifically, since the gas discharged from fermentation tank 3 contains a certain amount of volatile alcohol or acetic acid, direct discharge may have a certain impact on the factory environment. To overcome the above problems, in this embodiment, the top of the vinegar storage tank 22 is connected to the lower inlet of the absorption tower 11 through a pipeline, and the top of the absorption tower 11 is connected to the exhaust pipe 12. In this utility model, the gas discharged from fermentation tank 3 enters the vinegar storage tank 22 through a pipeline, then passes through the absorption tower 11 through a pipeline for absorption, and is discharged through the exhaust pipe 12, thereby absorbing the volatile alcohol or acetic acid in the air and ensuring that the factory environment is not polluted.
[0018] Specifically, the bottom of the air pressure control box 1 is provided with a filter screen 13. The filter screen 13 can prevent dust from entering the fermentation tank 3 with the air, thereby avoiding unnecessary impurities from entering the fermentation tank 3 and affecting the liquid fermentation vinegar brewing in the fermentation tank 3, and ensuring the normal progress of the liquid fermentation vinegar brewing.
[0019] Further, since the air may contain a certain amount of bacteria in addition to dust and other impurities, if these bacteria continue to enter the fermentation tank 3 with the air, it may affect the liquid fermentation vinegar brewing. In order to overcome the above problems, the air pressure control box 1 is provided with at least one filter drawer opening 14 on one side, the filter drawer opening 14 can be inserted and matched with the filter drawer 15, the corresponding position of the filter drawer 15 in the air pressure control box 1 is provided with a placement plate 16, the central position of the placement plate 16 is provided with a circular groove 17, the bottom of the filter drawer 15 is provided with a circular hole 18 at the corresponding position of the circular groove 17, the circular hole 18 is provided with a barrier net 19, the outer side of the filter drawer 15 is provided with a handle 20, and the filter drawer 15 can place an adsorbent. In the utility model, the air entering the fermentation tank 3 is further removed of fine dust and bacteria by placing an adsorbent (activated carbon, high-purity cotton, etc.) in the filter drawer 15, thereby ensuring the normal progress of the liquid fermentation, and the number of filter drawers 15 and the types of adsorbents placed therein can be selected according to the needs, thereby ensuring the bacteria removal efficiency in the air, and the adsorbent in the filter drawer 15 can be conveniently replaced regularly, thereby facilitating use.
[0020] Further, since the adsorbent in the filter drawer 15 may be sucked into the fermentation tank 3 by the air pump 2, thereby possibly affecting the quality of the acid liquid, in order to overcome the above problems, the filter drawer 15 is provided with a mesh plate 21 on the top, and the mesh plate 21 is hingedly connected to the end of the filter drawer 15 away from the handle 20. The mesh plate 21 can prevent the adsorbent in the filter drawer 15 from being sucked into the fermentation tank 3 by the air pump 2, and when the mesh plate 21 is inserted into the air pressure control box 1 with the filter drawer 15, the end of the mesh plate 21 away from the hinge can be located between the filter drawer 15 and the filter drawer opening 14, thereby conveniently fixing the mesh plate 21.
[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, and not to limit them; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacements for some technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
