[0008] And a stirring paddle, one end of which is close to the bottom of the tank, and the other end of which passes through a sealing assembly and is fixedly connected to the output end of the power source.
[0009] By adopting the above technical solution, unlike the sealing components of the prior art, the sealing component of this utility model is the opposite of the conventional setting method. The fixing part is built into the tank body and the sealing part protrudes out of the tank body. The sealing part of the sealing component is tightly matched with the stirring paddle to prevent air from entering the tank body along the stirring paddle. When in use, water or other liquids are injected into the support through the second through hole, which not only seals the tank but also has a cooling effect.
[0010] Furthermore, the tank body includes a top cover, a base plate, and a glass tube. The first through hole is opened at the center of the top cover, and the glass tube is disposed between the top cover and the base plate. The top cover and the base plate are fixedly connected by multiple studs.
[0011] By adopting the above technical solution, the glass tube is sandwiched between the top cover and the bottom plate, and the tank is in a sandwich state. The fermentation status can be observed in real time through the glass tube, and the glass tube is located in a space surrounded by multiple studs, avoiding collision with objects and damage.
[0012] Furthermore, a heating groove is provided in the lower part of the chassis, and a heating diaphragm is provided in the heating groove.
[0013] By adopting the above technical solution, the chassis is heated by a heating diaphragm, and the temperature of the fermenter is adjusted by heat conduction from the chassis to meet the fermentation requirements of different temperatures.
[0014] Furthermore, the top cover is a flange, and the base is a blind flange.
[0015] By adopting the above technical solution, the tank body can be produced using existing conventional and compatible parts, saving processing steps and costs.
[0016] Furthermore, a fixing ring is provided between the support body and the sealing part, and the fixing ring is fixedly connected to the support.
[0017] By adopting the above technical solution, a support can be formed between the sealing part and the support body, thereby increasing the stability of the sealing part.
[0018] Furthermore, the support body and the connecting part are connected, the connecting part is a hollow cuboid, and a motor is fixedly connected to the connecting part.
[0019] By adopting the above technical solution, the motor is fixed to the connection part of the support, and the output end of the motor is accommodated in the main body of the support, which facilitates the connection between the output end of the motor and the stirring paddle.
[0020] Furthermore, the fermenter also includes an aeration pipe, which comprises an annular pipe and a vertical pipe. The annular pipe abuts against the chassis, and the vertical pipe is perpendicular to the chassis. One end of the vertical pipe is connected to the annular pipe, and the other end of the vertical pipe passes through the chassis and is connected to an air source.
[0021] By adopting the above technical solution, the gas enters the fermenter through the vertical pipe and exits through the annular pipe, thus the gas is discharged from the bottom of the fermenter. Combined with the stirring action of the agitator, the gas distribution becomes more uniform.
[0022] Furthermore, the annular tube is provided with a plurality of aeration holes, which are evenly distributed on the annular tube.
[0023] By adopting the above technical solution, gas overflows through multiple aeration holes, increasing the efficiency and uniformity of ventilation.
[0024] Furthermore, the stirring paddle includes a stirring shaft and a plurality of blades fixedly connected thereto. The stirring shaft is fixedly connected to the output end of the motor. The plurality of blades are distributed in at least one layer, with each layer of blades arranged in a radiating pattern centered on the stirring shaft.
[0025] By adopting the above technical solution, the blades are fixed in a needle shape and perpendicular to the stirring shaft. When the stirring shaft rotates under the action of power, each layer of blades rotates accordingly, thereby fully stirring or crushing the material.
[0026] In summary, this utility model has at least one of the following beneficial technical effects:
[0027] 1. By adopting the above technical solution, the micro fermenter support of this utility model is tightly sealed, preventing airborne bacteria from entering the tank and causing contamination, while also cooling the temperature.

[0035] The present invention will be further described in detail below with reference to the accompanying drawings.
[0036] To facilitate understanding of this utility model by those skilled in the art, the following description is provided in conjunction with the accompanying drawings. Figure 1-5The specific embodiments of this utility model are described below.
[0037] Reference Figure 1-5 This utility model discloses a micro fermentation tank, which includes a tank body 1, a sealing component 4, a stirring paddle 6 and a motor 3.
[0038] Reference Figure 1 and Figure 2 The tank 1 has a first through hole 11 at its upper part and is vertically fixed to a support 2. The tank 1 includes a top cover 12, a base 13, and a glass tube 14. The first through hole 11 is located at the center of the top cover 12. The glass tube 14 is positioned between the top cover 12 and the base 13, which are fixedly connected by multiple studs 15. The glass tube 14 is sandwiched between the top cover 12 and the base 13, creating a sandwich-like structure. The fermentation status can be observed in real time through the glass tube 14, which is located within the space surrounded by the studs 15, preventing damage from collisions. A heating groove 131 is located at the lower part of the base 13. A heating diaphragm (not shown in the figure) is installed within the heating groove 131. The heating diaphragm heats the base 13, and the temperature of the fermentation tank is adjusted through heat conduction from the base 13 to meet different fermentation requirements. The top cover 12 is a flange and the bottom plate 13 is a blind flange. The tank body 1 can be produced using existing conventional and compatible parts, saving processing steps and costs.
[0039] The support 2 includes a support body 21 and a connecting part 22. The support body 21 is a hollow cylindrical structure, and a second through hole 23 is provided on the side wall of the support body 21. The support body 21 and the connecting part 22 are connected. The connecting part 22 is a hollow cuboid, and the motor 3 is fixedly connected to the connecting part 22.
[0040] Reference Figure 4 The sealing assembly 4 includes a sealing fixing part 41 and a sealing part 42, which are connected. The sealing fixing part 41 is disposed inside the tank body 1 and abuts against the upper part of the tank body 1. The sealing part 42 passes through the first through hole 11 and is accommodated in the support body 21. The outer side of the sealing part 42 is provided with threads, and the sealing part 42 is fixedly connected to the tank body 1. A fixing ring 5 is provided between the support body 21 and the sealing part 42. The fixing ring 5 is fixedly connected to the support 2 and can form a support between the sealing part 42 and the support body 21, increasing the stability of the sealing part 42.
[0041] Reference Figure 5One end of the agitator 6 is close to the bottom of the tank 1, and the other end passes through the sealing assembly 4 and is fixedly connected to the output end of the motor 3. The agitator includes an agitator shaft 61 and multiple blades 62 fixedly connected to it. The agitator shaft 61 is fixedly connected to the output end of the motor 3, and the multiple blades 62 are distributed in at least one layer, with each layer of blades 62 arranged radially around the agitator shaft 61. The blades 62 are fixed in a needle shape and perpendicular to the agitator shaft 61. When the agitator shaft 61 rotates under the action of power, each layer of blades 62 rotates accordingly, thereby fully agitating or crushing the material.
[0042] Reference Figure 5 The fermenter also includes an aeration pipe 7, which consists of an annular pipe 71 and a vertical pipe 72. The annular pipe 71 abuts against the base plate 13, and the vertical pipe 72 is perpendicular to the base plate 13. One end of the vertical pipe 72 is connected to the annular pipe 71, and the other end passes through the base plate 13 and is connected to the gas source. Gas enters the fermenter through the vertical pipe 72 and exits through the annular pipe 71, thus venting the gas from the bottom of the fermenter. Combined with the stirring action of the agitator 6, this makes the gas distribution more uniform. Multiple aeration holes 73 are evenly distributed on the annular pipe 71. Gas overflows through the multiple aeration holes 73, increasing the efficiency and uniformity of aeration.
[0043] The implementation principle of this embodiment is as follows: The sealing component 4 of this utility model differs from conventional methods in that the fixing part is built into the tank body 1, and the sealing part 42 protrudes outside the tank body 1. The sealing part 42 of the sealing component 4 is tightly fitted with the stirring paddle 6, preventing air from entering the tank body 1 along the stirring paddle 6. During use, water or other liquids are injected into the support 2 through the second through hole 23, which not only seals the tank but also cools it down. The top cover 12 is a flange, and the base 13 is a blind flange. The tank body 1 is manufactured using conventionally compatible existing components, saving processing steps and costs. Furthermore, the tank body 1 is a glass tube 14, small in size and available in various specifications. Its compatibility with the flange and blind flange allows it to meet the equipment needs of different fermentation volumes.
