Description

Technical Field

[0001] This utility model relates to the field of probiotic fermentation technology, and in particular to a probiotic liquid fermentation device. Background Art

[0002] The main component of probiotic liquid is probiotics, typically including various types such as lactic acid bacteria, bifidobacteria, and Lactobacillus acidophilus. A fermentation device is required during the preparation of probiotic liquid. Publication number CN215799576U discloses a fermentation device for cultivating probiotics, including a fermenter. A drive motor is installed at the top of the fermenter, and a feed pipe is installed at the top of the right side of the fermenter. A sealing cap is installed at the top of the feed pipe. Discharge valves are installed at the left and right sides of the bottom of the fermenter. A heater is installed inside the fermenter. A drive shaft is installed between the output end of the motor and the top of the heater, and the drive shaft is rotatably connected to the top of the heater. A connecting shaft is installed at the bottom of the drive shaft.

[0003] The aforementioned prior art controls the temperature of probiotic liquid fermentation by using a heater located in the middle of the fermentation tank. However, since the heater is located in the middle of the fermentation tank, only the probiotic liquid in the middle can come into contact with the heater, while the probiotic liquid far from the heater and close to the tank wall cannot come into contact with the heater. This results in the temperature of the probiotic liquid being higher closer to the heater, leading to uneven heating of the probiotic liquid by the heater. Utility Model Content

[0004] (I) Purpose of the utility model

[0005] In view of this, the purpose of this utility model is to propose a probiotic liquid fermentation device. The technical problem it aims to solve is that because the heater is set in the middle of the fermentation tank, the temperature inside the probiotic liquid is higher closer to the heater, resulting in uneven heating of the probiotic liquid by the heater.

[0006] (II) Technical Solution

[0007] To achieve the above technical objectives, this utility model provides a probiotic liquid fermentation device:

[0008] It includes a fermenter, in which a rotating shaft is rotatably connected in a sealed manner, with both the top and bottom of the rotating shaft extending outside the fermenter. Multiple hollow stirring rods are fixed at equal intervals along the radial direction of the rotating shaft, and these hollow stirring rods are located inside the fermenter. An upper chamber and a lower chamber are respectively formed at the top and bottom of the rotating shaft. One end of each hollow stirring rod is connected to the upper chamber, and the other end of each hollow stirring rod is connected to the lower chamber. An air heating assembly is provided at the top of the fermenter, and an air guiding assembly is provided at the bottom of the fermenter for conveying heated air to the hollow stirring rods and heating them.

[0009] Preferably, the air heating assembly includes a first U-shaped frame fixed to the top of the fermenter, a first air guide pipe fixed inside the first U-shaped frame and extending into the upper chamber, the rotating shaft and the first air guide pipe being rotatably connected, and an electric heating element installed inside the first air guide pipe.

[0010] Preferably, the gas guiding assembly includes an L-shaped support plate fixed to the bottom of the fermenter, an air pump is installed on the L-shaped support plate, a second gas guiding pipe is installed at the air intake of the air pump, and the second gas guiding pipe extends into the lower chamber, and the rotating shaft and the second gas guiding pipe are rotatably connected.

[0011] Preferably, the hollow stirring rod is W-shaped.

[0012] Preferably, a second U-shaped frame is fixed to the top of the fermentation tank, and a rotating rod is rotatably connected between the second U-shaped frame and the fermentation tank. A motor is installed on the top of the second U-shaped frame, and the end of the rotating rod extending outside the second U-shaped frame is fixed to the output end of the motor.

[0013] Preferably, a drive wheel is fixed to the outer side of the rotating rod, and a driven wheel is fixed to the outer side of the top of the rotating shaft. The driven wheel is located inside the first U-shaped frame, and the driven wheel and the drive wheel are driven by a belt.

[0014] As can be seen from the above technical solutions, this application has the following beneficial effects:

[0015] 1. When the air pump is started, air flows from the first air guide tube into the upper chamber, then from the upper chamber into the hollow stirring rod, then from the hollow stirring rod into the lower chamber, and then from the lower chamber into the second air guide tube. Finally, it is discharged to the outside by the air pump. The electric heating element heats the flowing air, causing the heated air to flow in the hollow stirring rod and be heated by the hollow stirring rod. The hollow stirring rod is also stirring, which increases the contact area between the air and the probiotic liquid, making the heating of the probiotic liquid more uniform.

[0016] 2: Because the hollow stirring rod is W-shaped, it not only makes the stirring more thorough, but its special structural design also increases the contact area between it and the probiotic liquid, which is beneficial for heating the probiotic liquid. Attached Figure Description

[0024] The following description is exemplary in nature and is not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of the various embodiments of this disclosure. Certain details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures.

[0025] Reference Figure 1-5 :

[0026] The probiotic liquid fermentation device includes a fermentation tank 1. A rotating shaft 2 is rotatably connected inside the fermentation tank 1 and extends to the outside of the fermentation tank 1 at both the top and bottom. Multiple hollow stirring rods 5 are fixed at equal intervals along the radial direction of the rotating shaft 2 and are located inside the fermentation tank 1. An upper chamber 3 and a lower chamber 4 are respectively opened at the top and bottom of the rotating shaft 2. One end of each of the multiple hollow stirring rods 5 is connected to the upper chamber 3 and the other end of each of the multiple hollow stirring rods 5 is connected to the lower chamber 4. The hollow stirring rods 5 are W-shaped.

[0027] Specifically, a second U-shaped frame 16 is fixed to the top of the fermentation tank 1. A rotating rod 17 is rotatably connected between the second U-shaped frame 16 and the fermentation tank 1. A drive wheel 14 is fixed to the outside of the rotating rod 17. A driven wheel 13 is fixed to the outside of the top of the rotating shaft 2. The driven wheel 13 is located inside the first U-shaped frame 11, and the driven wheel 13 and the drive wheel 14 are driven by a belt 15. A motor 18 is installed on the top of the second U-shaped frame 16. The end of the rotating rod 17 extending outside the second U-shaped frame 16 is fixed to the output end of the motor 18.

[0028] In addition, an air heating assembly is provided at the top of the fermentation tank 1, and an air guiding assembly is provided at the bottom of the fermentation tank 1 for conveying heated air into the hollow stirring rod 5 and heating the hollow stirring rod 5. The air heating assembly includes a first U-shaped frame 11 fixed to the top of the fermentation tank 1, a first air guiding pipe 6 fixed inside the first U-shaped frame 11, and the first air guiding pipe 6 extends into the upper chamber 3. The rotating shaft 2 and the first air guiding pipe 6 are rotatably connected. An electric heating element 7 is installed inside the first air guiding pipe 6. The air guiding assembly includes an L-shaped support plate 9 fixed to the bottom of the fermentation tank 1, an air pump 10 is installed on the L-shaped support plate 9, a second air guiding pipe 8 is installed at the air intake of the air pump 10, and the second air guiding pipe 8 extends into the lower chamber 4. The rotating shaft 2 and the second air guiding pipe 8 are rotatably connected.

[0029] It should be noted that the top and bottom of the fermentation tank 1 are respectively equipped with a feed pipe and a discharge pipe. In addition, the electric heating element 7, the air pump 10, and the motor 18 are all electrically connected to an external power source. When the motor 18 is started, it drives the rotating rod 17 and the drive wheel 14 to rotate. When the drive wheel 14 rotates, it drives the driven wheel 13 to rotate through the belt 15, which in turn drives the rotating shaft 2 to rotate. When the rotating shaft 2 rotates, it drives the hollow stirring rod 5 to rotate, so that the hollow stirring rod 5 stirs the probiotic liquid, which facilitates its fermentation.

[0030] It is worth mentioning that when the air pump 10 is started, the air flows as follows: from the first air guide tube 6 into the upper chamber 3, then from the upper chamber 3 into the hollow stirring rod 5, then from the hollow stirring rod 5 into the lower chamber 4, then from the lower chamber 4 into the second air guide tube 8, and finally is discharged to the outside through the air pump 10. When the electric heating element 7 is started, the outside air passes through the electric heating element 7, which heats the flowing air. This heated air flows through the hollow stirring rod 5, thus heating the hollow stirring rod 5. The hollow stirring rod 5 heats the probiotic liquid, and the stirring action of the hollow stirring rod 5 increases the contact area between it and the probiotic liquid, making the heating of the probiotic liquid more uniform.

[0031] The exemplary implementation of the solution proposed in this disclosure has been described in detail above with reference to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
