Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model discloses a fermentation tank structure for fermented milk production, including a tank body 1. A feeding pipe 2 is installed on the upper side wall of the tank body 1 near the rear side. A material distribution box 3 is fixedly installed on the upper surface of the tank body 1. A motor 4 is fixedly installed on the upper surface of the material distribution box 3. A transmission pipe 5 is fixedly installed on the lower surface of the output shaft of the motor 4 and is inserted into the tank body 1. A feeding hole 6 is opened on the front side wall of the transmission pipe 5 inside the material distribution box 3. A stirring mechanism 7 is provided inside the tank body 1. A tumbling mechanism 8 is provided on the lower side wall of the tank body 1 corresponding to the transmission pipe 5 and is installed on the lower side wall of the tank body 1. A liquid inlet mechanism 9 is installed on the left side wall of the material distribution box 3. The front side wall of the material distribution box 3 is connected to an adjustment mechanism 10 and the adjustment mechanism 10 is connected to the upper edge of the tank body 1. A monitoring mechanism 11 is provided on the upper side wall of the tank body 1 near the right side.

[0023] Specifically, mechanical seals 12 are provided on the upper and lower side walls of the material box 3 and the upper side wall of the tank body 1 corresponding to the transmission pipe 5.

[0024] In this embodiment, the mechanical seal 12 improves the sealing effect between the transmission pipe 5 and the corresponding upper and lower side walls of the material box 3 and the upper side wall of the tank body 1.

[0025] Specifically, the stirring mechanism 7 includes a distribution pipe 701, a branch pipe 702, a first check valve 703, and a nozzle 704. The distribution pipe 701 is installed on the left and right sides of the transmission pipe 5 near the upper edge. The branch pipes 702 are evenly distributed on the lower surface of the distribution pipe 701. The first check valve 703 is provided on the branch pipe 702 near the upper side, and the nozzles 704 are provided on both the left and right sides of the branch pipe 702.

[0026] In this embodiment, the material distribution pipe 701 rotates with the transmission pipe 5, the material distribution pipe 701 drives the branch pipe 702 to rotate, and the branch pipe 702 drives the nozzle 704 to rotate, thereby achieving the effect of stirring the raw materials in the tank 1. The first check valve 703 prevents the raw materials from flowing in, and the nozzle 704 makes the sprayed gas and liquid evenly distributed.

[0027] Specifically, a group of nozzles 704 near the upper inner wall of the tank 1 are inclined upwards at 45 degrees.

[0028] In this embodiment, the uppermost nozzle 704 can spray and clean the inner wall of the upper side of the tank 1.

[0029] Specifically, the tumbling mechanism 8 includes a feeding cylinder 801, a rectangular opening 802, a gate valve 803, and a spiral feeding rod 804. The feeding cylinder 801 is fixedly installed on the lower side wall of the tank body 1. The rectangular opening 802 is provided on the four side plates of the feeding cylinder 801 at a position flush with the upper surface of the lower inner wall of the tank body 1. The gate valve 803 is provided on the lower surface of the feeding cylinder 801. The spiral feeding rod 804 is installed opposite to the transmission tube 5 and is inserted into the feeding cylinder 801.

[0030] In this embodiment, the spiral feed rod 804 rotates in the transmission tube 5 inside the feed cylinder 801, causing the raw material inside the feed cylinder 801 to move upward. At this time, the raw material in the tank 1 flows into the feed cylinder 801 through the rectangular opening 802 and then flows out through the upper side of the feed cylinder 801, achieving the effect of tumbling the raw material.

[0031] Specifically, the liquid inlet mechanism 9 includes a liquid inlet pipe 901 and a second check valve 902. The liquid inlet pipe 901 is installed on the left side of the fabric box 3, and the second check valve 902 is provided on the liquid inlet pipe 901.

[0032] In this embodiment, the inlet pipe 901 is connected to the high-pressure pipe of the cleaning fluid, so that the cleaning fluid can flow into the fabric box 3 through the inlet pipe 901, and the second check valve 902 prevents the cleaning fluid from flowing back.

[0033] Specifically, the regulating mechanism 10 includes a bidirectional fan 101, an electric heating box 102, a semiconductor cooling box 103, a conduit 104, a third check valve 105, an electric three-way valve 106, and an air filter 107. The bidirectional fan 101, the electric heating box 102, and the semiconductor cooling box 103 are installed on the front side of the tank body 1. The tank body 1, the bidirectional fan 101, the electric heating box 102, the semiconductor cooling box 103, and the fabric box 3 are connected in series through the conduit 104. The third check valve 105 and the electric three-way valve 106 are provided on the side of the conduit 104 near the fabric box 3. The electric three-way valve 106 is connected to the air filter 107.

[0034] In this embodiment, the bidirectional fan 101 draws air from the tank 1 through the conduit 104. The drawn air is heated or cooled by the electric heating box 102 or the semiconductor cooling box 103, and then flows into the fabric box 3 through the conduit 104, thereby heating or cooling the tank 1. At this time, the electric three-way valve 106 is disconnected from the air filter 107. When the electric three-way valve 106 is connected to the air filter 107, the bidirectional fan 101 draws air from the tank 1 through the conduit 104, and then discharges the air after being filtered by the air filter 107, thereby reducing the air pressure inside the tank 1. When the bidirectional fan 101 draws air from the air filter 107 through the conduit 104, the air flows into the tank 1 through the left end of the conduit 104, thereby increasing the air pressure inside the tank 1.

[0035] Specifically, the monitoring mechanism 11 includes a controller 111, a temperature sensor 112, and a pressure sensor 113. The controller 111 is installed on the upper surface of the tank 1, and the temperature sensor 112 and the pressure sensor 113 are provided on the lower surface of the controller 111. The temperature sensor 112 and the pressure sensor 113 are inserted into the tank 1.

[0036] In this embodiment, the controller 111 can monitor the temperature and pressure inside the tank 1 through the temperature sensor 112 and the pressure sensor 113, and the controller 111 can control the regulating mechanism 10.

[0037] In use, open the sealing cap on the feeding pipe 2 and pour the fermented milk raw material into the tank 1. The height of the raw material should not exceed the feeding pipe 701. Then, screw the sealing cap onto the feeding pipe 2. During fermentation, the output shaft of the motor 4 drives the transmission pipe 5 to rotate. The transmission pipe 5 drives the feeding pipe 701 in the stirring mechanism 7 to rotate. The feeding pipe 701 drives the branch pipe 702 to rotate. The branch pipe 702 drives the nozzle 704 to rotate, stirring the fermented milk raw material in the tank 1. At the same time, the transmission pipe 5 drives the spiral feeding rod 804 in the tumbling mechanism 8 to rotate inside the feeding cylinder 801, causing the raw material in the feeding cylinder 801 to move upward. At this time, the raw material in the tank 1 flows into the feeding cylinder 801 through the rectangular opening 802. 1. The raw materials flow out through the upper side of the feeding cylinder 801, achieving a tumbling effect, thus making the fermented milk raw materials more uniform and faster. The controller 111 in the monitoring mechanism 11 can monitor the temperature and pressure inside the tank 1 through the temperature sensor 112 and the air pressure sensor 113, and the controller 111 controls the regulating mechanism 10. When the temperature of the fermented milk inside the tank 1 is higher or lower than the set value, the bidirectional fan 101 in the regulating mechanism 10 draws air from the tank 1 through the conduit 104. The drawn air is heated or cooled through the electric heating box 102 or the semiconductor cooling box 103, and then flows into the distribution box 3 through the conduit 104, and then into the transmission through the feed hole 6. The gas flows into the distribution pipe 701 through the transmission pipe 5, and out through the nozzle 704 on the branch pipe 702. The nozzle 704 rotates with the branch pipe 702, ensuring uniform gas flow and thus heating or cooling the tank 1. At this time, the electric three-way valve 106 is disconnected from the air filter 107. When the air pressure inside the tank 1 is higher or lower than the set value, the controller 111 connects the electric three-way valve 106 to the air filter 107. The bidirectional fan 101 then draws air from the tank 1 through the conduit 104, filters it through the air filter 107, and discharges it, thereby reducing the air pressure inside the tank 1. When the bidirectional fan 101 draws air from the air filter 107 through the conduit 104... Gas is allowed to flow into tank 1 through the left end of conduit 104, thereby increasing the gas pressure inside tank 1. This allows for precise regulation of the temperature and pressure of the fermented milk inside tank 1, resulting in better fermentation quality. After fermentation, gate valve 803 is opened to allow the fermented milk to flow out. After the milk flows out, it is connected to the high-pressure cleaning liquid pipe through inlet pipe 901 in liquid inlet mechanism 9, allowing the cleaning liquid to flow into distribution box 3 through inlet pipe 901, then into transmission pipe 5 through inlet hole 6, and then into distribution pipe 701 through transmission pipe 5. Finally, it is sprayed out through nozzle 704 on branch pipe 702. At this time, nozzle 704 is in a rotating state, which increases the cleaning function inside tank 1, reduces fermented milk residue, and facilitates subsequent use.

[0038] In summary, the fermentation tank structure for fermented milk production has the functions of stirring and tumbling fermented milk, which makes the raw materials more uniform and faster. It can accurately regulate the temperature and air pressure of the fermented milk in tank 1, resulting in better fermentation quality. In addition, the internal cleaning function of tank 1 is added, which is beneficial for subsequent use.
