[0042] In an optional embodiment, such as Figure 1 As shown, the steam layer 12 is provided with an inlet 121 and an outlet 122 that connect to the outside of the fermentation tank 10, so as to introduce steam or cooling water into the steam layer 12. This is used to regulate the temperature inside the fermentation tank 10.

[0043] In a preferred embodiment, such as Figures 2-3 As shown, the steam layer 12 is further provided with a steam overflow port 123 connecting to the outside of the fermentation tank body 10. More preferably, the liquid outlet 122 and the steam overflow port 123 are respectively located at both ends of the fermentation tank body 10, wherein the steam overflow port 123 is positioned higher than the liquid outlet 122. The steam overflow port 123 is suitable for preventing excessively high steam pressure inside the fermentation tank, and the liquid outlet 122 is suitable for steam circulation and discharge.

[0044] In an optional embodiment, such as Figure 1 As shown, the cleaning port 13 is located at the bottom of one end of the fermentation tank body 10, and the bottom of the fermentation tank body 10 is inclined towards the cleaning port 13 to facilitate the outflow of materials. In a preferred embodiment, the cleaning port 13 is located at the bottom of the fermentation tank body 10 on the side of the liquid outlet 122.

[0045] In an optional embodiment, such as Figure 2 As shown, the bottom of the fermentation tank 10 is also equipped with casters 16 to facilitate the movement of the multifunctional fermentation tank.

[0046] In an optional embodiment, temperature sensors are installed both inside the fermentation tank 10 and in the steam layer 12. All sensors are PT100 models. They can reflect the temperature inside the reaction tank 10 and the steam layer 12 respectively, and by combining the temperature readings of both, hot steam or cooling water can be introduced into the steam layer 12 in a timely manner to adjust the temperature.

[0047] The fermentation tank 10 is also equipped with a pH electrode sensor and a dissolved oxygen sensor. The pH electrode sensor is pH-820c. The dissolved oxygen sensor is RY-830F.

[0048] In an optional embodiment, a display device is also provided on the outside of the fermentation tank 10. The display device includes a power module, an output module, and a display screen. The power module, output module, and display screen are all located on the outer wall of the fermentation tank 10. The output module is electrically connected to a temperature sensor, a pH electrode sensor, a dissolved oxygen sensor, and the display screen. The temperature sensor, pH electrode sensor, dissolved oxygen sensor, output module, and display screen are respectively electrically connected to the power module.

[0049] In use, the above-mentioned device of this utility model is used for the rice soaking and steaming processes in the brewing of rice wine: First, close the cleaning port 13 and the gas connection port 14, and pour rice and water into the fermentation tank 10 for settling. During the settling process, the pH of the rice slurry can be detected by a pH electrode sensor. After soaking for 24-72 hours, fix the mesh screen 30 to the mesh screen reinforcing rib 15 inside the fermentation tank 10, and connect a pipe and pump to the cleaning port 13. Through the cleaning port 13, the rice slurry and rice in the fermentation tank 10 are circulated into the fermentation tank 10 from the top. During this process, the mesh screen 30 catches the rice, and the rice slurry is filtered out, thus separating the rice and the rice slurry. Then, close the cleaning port 13 and pour clean water into the tank from the top of the fermentation tank 10. The amount of water should be moderate; the water level should not be too high, overflowing the mesh screen, nor too low, resulting in undercooked rice due to short steaming time. After watering, the rice on the mesh screen 30 is evenly spread, the fermentation tank cover 20 is closed, and the inlet 121 and outlet 122 are opened to introduce hot steam into the steam layer 12 for heating. During this process, some steam can be released through the overflow port 17 to prevent excessive pressure inside the fermentation tank 10. The mesh screen 30 also ensures that the rice is heated evenly. After steaming, the cleaning port 13 is opened to drain the steaming water from the fermentation tank 10, and gas is introduced into the fermentation tank 10 through the gas connection port 14 to quickly cool the rice on the mesh screen 30.

[0050] The fermentation process in rice wine brewing using the above-mentioned device of this utility model is as follows: In the feeding stage, the mesh screen 30 is removed, the cleaning port 13 and the gas connection port 14 are closed, rice is placed into the fermentation tank 10, the rice wine raw materials are added into the fermentation tank 10 according to a certain ratio, stirred evenly, the fermentation tank cover 20 is covered, and the overflow port 17 of the tank is opened to prevent the fermentation from violently impacting the fermentation tank cover 20. During fermentation, the temperature inside the fermentation tank 10 and the temperature in the steam layer 12 can be monitored in real time by temperature sensors in the fermentation tank 10 and the steam layer 12, respectively. When the temperature inside the fermentation tank 10 is too high or too low, the liquid inlet 121 and the liquid outlet 122 can be opened to introduce cooling water or hot steam for temperature control. The gas connection port 14 is then connected to the gas supply to control the gas pressure and agitate the mash inside the fermentation tank 10. In addition, pH electrode sensors and dissolved oxygen sensors can quickly obtain the pH value and dissolved oxygen content of the rice wine during fermentation, helping to understand the changes in pH value and dissolved oxygen content, thereby improving the quality of the rice wine. After fermentation, the mesh screen 30 is installed, and the cleaning port 13 is opened. The fermentation mash is then pumped into the fermentation tank 10 from the top through the cleaning port 13. During this process, the mesh screen 30 filters the residue, achieving separation of the wine and the residue. After the rice wine and residue are removed separately, the inside of the fermentation tank 10 can be directly cleaned for the next use, greatly reducing the difficulty of removing residue and cleaning the tank after the rice wine fermentation is completed.

[0051] In summary, the multifunctional fermentation tank for rice wine brewing of this invention can realize rice soaking, rice steaming, saccharification and fermentation processes. With the addition of temperature, pH and dissolved oxygen sensors, brewing efficiency can be improved and brewing costs can be reduced by further optimizing monitoring conditions.

[0052] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0053] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
