Description

Technical Field

[0001] This utility model relates to the field of fermentation equipment technology, specifically to a deep liquid fermentation device for acetic acid. Background Technology

[0002] Acetic acid deep liquid fermentation technology is a modern vinegar-making process that produces acetic acid through deep fermentation in a liquid environment. This technology is characterized by a short fermentation cycle, high labor productivity, low labor intensity, small footprint, and the elimination of the need for filler materials.

[0003] In existing acetic acid deep liquid fermentation devices, a large number of bubbles are generated during the fermentation process and stirring. These bubbles severely affect normal stirring, and excessive bubbles also reduce the fermentation speed. Furthermore, the entire fermentation cycle is long and the production efficiency is low. Utility Model Content

[0004] The purpose of this invention is to provide a deep liquid fermentation device for acetic acid. During the deep fermentation process, a large amount of air is injected using an air pump to increase the oxygen content in the internal liquid, thereby improving fermentation efficiency. When air is not injected, an air pump is turned on to remove excess gas from the fermentation tank. This not only reduces the negative impact of bubbles during fermentation but also maintains the circulation of internal gas, promoting fermentation. In the later stages of fermentation, mature mash can be added, and a semi-continuous fermentation method can be used for further fermentation, improving the stability of fermentation and production efficiency.

[0005] To achieve the above objectives, a deep liquid acetic acid fermentation device is provided, comprising: a fermentation tank; an operation display fixedly connected to the circumferential surface of the fermentation tank; a main motor fixedly connected to the top of the fermentation tank; a stirring shaft rotatably connected to the inner top surface of the fermentation tank; stirring blades fixedly connected to the stirring shaft; multiple stirring blades evenly distributed on the stirring shaft; three oxygen concentration sensors fixedly connected to the inner circumferential surface of the fermentation tank, evenly distributed vertically on the inner wall of the fermentation tank; an acetic acid sensor fixedly connected to the inner circumferential surface of the fermentation tank; an air pump fixedly connected to the circumferential surface of the fermentation tank; and a vacuum pump and an auxiliary addition box fixedly connected to the top of the fermentation tank, the vacuum pump and the auxiliary addition box being located on the left and right sides of the main motor, respectively.

[0006] According to the aforementioned acetic acid deep liquid fermentation device, the auxiliary addition tank is filled with fermented mash, and an inlet pipe and an outlet pipe are respectively provided at the top and bottom of the auxiliary addition tank. The outlet pipe at the bottom of the auxiliary addition tank penetrates through the fermentation tank. Semi-continuous fermentation can be carried out in the later stages of fermentation, improving fermentation efficiency and stability.

[0007] According to the aforementioned acetic acid deep liquid fermentation device, a feeding pipe is fixedly connected to the top of the fermentation tank, and a discharge pipe is fixedly connected to the bottom of the fermentation tank. These are used for adding fermentation raw materials and discharging the fermented liquid.

[0008] According to the aforementioned acetic acid deep liquid fermentation device, an air inlet pipe and an air outlet pipe are respectively provided on the left and right side walls of the air pump, and the air outlet pipe of the air pump penetrates through the fermentation tank. Activating the air pump aerates the inside of the fermentation tank, increasing the oxygen content of the internal liquid.

[0009] According to the aforementioned acetic acid deep liquid fermentation device, the bottom of the fermentation tank is fixedly connected to a support column, and the support column is provided in multiple quantities and evenly distributed at the bottom of the fermentation tank.

[0010] According to the aforementioned acetic acid deep liquid fermentation device, the top and bottom of the vacuum pump are respectively equipped with an air inlet pipe and an air outlet pipe, with the bottom air inlet pipe of the vacuum pump penetrating the fermentation tank. Activating the vacuum pump extracts excess gas from inside the fermentation tank, thereby accelerating the bursting of internal bubbles and reducing the negative impact of bubbles on fermentation.

[0011] According to the aforementioned acetic acid deep liquid fermentation device, solenoid valves are installed on the air outlet pipe of the aeration pump, the air inlet pipe of the extraction pump, and the discharge pipe of the auxiliary additive box. These solenoid valves are electrically connected to the main motor, the aeration pump, the extraction pump, the oxygen concentration sensor, and the acetic acid sensor, all of which are connected to the operation display. This facilitates the operation display's control of the various components, ensuring their orderly operation.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up a fermentation tank, operation display, main motor, stirring shaft, stirring blade, oxygen concentration sensor, acetic acid sensor, air pump, vacuum pump, and auxiliary addition box, a large amount of air is injected during deep fermentation using the air pump, thereby increasing the oxygen content in the internal liquid and improving fermentation efficiency. When not air-filling, the vacuum pump is turned on to remove excess gas from the fermentation tank, which not only reduces the negative impact of bubbles during fermentation but also maintains the circulation of internal gas, promoting fermentation. When fermentation reaches the later stage, mature mash can be added, and semi-continuous fermentation can be used for further fermentation, improving the stability of fermentation and production efficiency.

When the air pump 8 is started, it can aerate the inside of the fermentation tank 1, increasing the oxygen content of the liquid inside. An air pump 9 has an inlet pipe and an outlet pipe at its top and bottom, respectively. The bottom inlet pipe of the air pump 9 passes through the fermentation tank 1. When the air pump 9 is started, it can extract excess gas from the inside of the fermentation tank 1, thereby accelerating the bursting of internal bubbles and reducing the negative impact of bubbles on fermentation. The auxiliary addition box 10 is filled with mash, and the top and bottom of the auxiliary addition box 10 are respectively equipped with feeding ports. The bottom discharge pipe of the auxiliary addition box 10 passes through the fermentation tank 1.

[0024] Working principle: In the early stage of deep fermentation, the main motor 3 is started to rotate the stirring shaft 4 and stirring blades 5 to fully stir the internal liquid. At the same time, the air pump 8 is started to aerate the inside of the fermentation tank 1 to increase the oxygen content of the internal liquid. Then the air pump 8 is turned off and the vacuum pump 9 is started to extract the excess gas inside the fermentation tank 1, thereby accelerating the bursting of internal bubbles and reducing the negative impact of bubbles on fermentation. This process is repeated. When fermentation reaches the later stage, mature mash can be added to the fermentation tank 1 through the auxiliary addition box 10 to carry out semi-continuous fermentation, thereby improving the stability of fermentation and production efficiency.
