[0034] like Figure 1-11 As shown, the dairy product fermentation device is described in detail:

[0035] A dairy product fermentation device comprises a bottom plate 101 fixed to the lower end of an outer cylinder 102, a mounting frame 105 is fixed to the lower end surface of the bottom plate 101, a transmission wheel 303 is rotatably provided on the mounting frame 105, a middle tube 301 is connected inside the transmission wheel 303, the upper end of the middle tube 301 passes through the bottom plate 101 and is fixed with a tripod 302, a plurality of air holes 306 are provided on the lower end surface of the tripod 302, an air pipe frame 305 is rotatably provided at the lower end of the middle tube 301, a cover plate 201 is fixed to the upper end of the outer cylinder 102, an addition pipe 202 is provided on the cover plate 201, and a discharge pipe 106 is provided at the lower end of the bottom plate 101.

[0036] The addition pipe 202 and the discharge pipe 106 are both provided with valves, and the cover plate 201 is provided with a pressure relief valve;

[0037] The outer cylinder 102, the bottom plate 101 and the cover plate 201 form a fermentation chamber. During fermentation, the emulsion mixed with the strain is added into the fermentation chamber through the adding tube 202 for fermentation. When oxygen needs to be introduced into the emulsion, the air pipe rack 305 is connected with the oxygen supply device, and then the oxygen passes through the air pipe rack 305, the middle pipe 301, the tripod 302, and then blown into the emulsion through the air hole 306. During this process, the transmission wheel 303 rotates, and then the tripod 302 is driven by the middle pipe 301 to stir the emulsion, so that the oxygen is fully in contact with the emulsion, so that the strain can be fully in contact with the oxygen for reproduction, and the fermentation efficiency is guaranteed;

[0038] Among them, since the air hole 306 is located at the lower end of the tripod 302, rotating the tripod 302 can disperse the oxygen blown out of the air hole 306, so that the oxygen can better contact with the emulsion.

[0039] like Figure 1-11 As shown:

[0040] An inner tube 103 is fixed on the bottom plate 101 , the tripod 302 is located in the inner tube 103 , a piston block 401 slides in the inner tube 103 , a middle rod 402 is fixed to the upper end of the piston block 401 , the middle rod 402 passes through the cover plate 201 , and a plurality of connecting holes 104 are provided at the lower end of the inner tube 103 .

[0041] The piston block 401 can be driven to reciprocate and rise in the inner tube 103 by the reciprocating lifting of the transmission middle rod 402, so that the emulsion will be sucked into the inner tube 103 or pushed out of the inner tube 103 through the connecting hole 104, so that the emulsion reciprocates in and out of the inner tube 103, and the tripod 302 is located in the inner tube 103 for stirring and oxygen supply. The emulsion that reciprocates in and out of the inner tube 103 and flows rapidly will be better in contact with oxygen, and further enable the bacteria to fully contact with oxygen for reproduction, thereby ensuring the fermentation efficiency;

[0042] Moreover, the tripod 302 is located in the inner tube 103 to stir and supply oxygen, so that after the oxygen is blown out by the tripod 302, it is first located in a small space in the inner tube 103 to fully contact and consume with the emulsion, and then reciprocates through the piston block 401 to enter the outer tube 102, and then floats upward until it is separated from the emulsion. Therefore, the setting of the inner tube 103 increases the time that oxygen stays in the emulsion, thereby improving the utilization rate of oxygen.

[0043] like Figure 1-11 As shown:

[0044] A slide frame 203 is fixed on the cover plate 201, a slide seat 404 is fixed on the upper end of the middle rod 402, the slide seat 404 slides through the slide frame 203, a rotating wheel shaft 502 rotates on the cover plate 201, an eccentric wheel 403 rotates on the slide seat 404, and a tension spring 405 is provided between the slide seat 404 and the cover plate 201 to press the eccentric wheel 403 against the rotating wheel shaft 502.

[0045] The eccentric wheel 403 can be driven to rotate by the driving wheel shaft 502, so that the slide seat 404 can be lifted and lowered on the slide column frame 203, and then the middle rod 402 and the piston block 401 can be lifted and lowered.

[0046] The tension spring 405 ensures that the eccentric wheel 403 is always pressed downward against the rotating wheel shaft 502 .

[0047] like Figure 1-11 As shown:

[0048] A spring I 304 is provided between the transmission wheel 303 and the middle tube 301 to enable the middle tube 301 to move upward with the tripod 302 .

[0049] When the fermented emulsion of the fermentation device does not need to be fed with gas into the fermentation chamber, the middle tube 301 is pulled downward to overcome the elastic force of the spring I 304, so that the lower end of the tripod 302 is attached to the upper end surface of the bottom plate 101, thereby forming a shield for the multiple air holes 306, thereby preventing the emulsion from entering the middle tube 301 through the air holes 306 to cause leakage, and preventing the emulsion from entering the middle tube 301 and being unable to be discharged;

[0050] The middle tube 301 and the transmission wheel 303 are slidably connected via a key, so that when the middle tube 301 moves, the transmission of the transmission wheel 303 to the middle tube 301 is not affected.

[0051] like Figure 1-11 As shown:

[0052] The slide bracket 203 is threadedly connected with an adjusting screw 406 , which passes through the slide seat 404 and the middle rod 402 .

[0053] When there is no need to introduce gas into the fermentation chamber, the adjusting screw 406 is rotated to make the adjusting screw 406 move circumferentially on the sliding column frame 203, thereby driving its own bare rod part to move in the middle rod 402, tightening the upper end of the tripod 302, and then making the lower end of the tripod 302 fit against the upper end surface of the bottom plate 101, thereby forming a shielding for the multiple air holes 306.

[0054] like Figure 1-11 As shown:

[0055] The bottom plate 101 and the cover plate 201 are rotatably provided with a power shaft 501 , and the upper and lower ends of the power shaft 501 are respectively connected to the rotating wheel shaft 502 and the transmission wheel 303 .

[0056] The first motor installed on the outer cylinder 102 drives the power shaft 501, so that the rotating wheel shaft 502 and the driving wheel 303 can be driven to rotate at the same time, so that the tripod 302 rotates and the piston block 401 reciprocates and rises and falls.

[0057] like Figure 1-11 As shown:

[0058] Wall seats 107 are provided at locations of the plurality of communication holes 104 corresponding to the outer cylinder 102 , rod frames 602 are connected to the plurality of wall seats 107 , and mesh plates 601 are fixed to the inner ends of the plurality of rod frames 602 .

[0059] By arranging the mesh plate 601 at the connecting hole 104, when the emulsion flows back and forth at the connecting hole 104, it will pass through the mesh plate 601, and the mesh plate 601 will separate the flowing emulsion, so that the emulsion can better contact with the oxygen therein.

[0060] like Figure 1-11 As shown:

[0061] Springs II 603 are provided between the two ends of the rod frame 602 and the wall seat 107 respectively.

[0062] When the emulsion impacts the mesh plate 601, the mesh plate 601 will overcome the elastic force of the spring II 603 and vibrate back and forth, thereby forming a better cutting of the emulsion and further making the emulsion better contact with the oxygen inside.

[0063] like Figure 1-11 As shown:

[0064] The air pipe frame 305 and the mounting frame 105 slide with limited position.

[0065] By limiting the position of the trachea rack 305, the trachea rack 305 is prevented from rotating with the middle pipe 301, and at the same time, the connection between the trachea rack 305 and the oxygen supply device is ensured to always face one direction to avoid entanglement of the connected pipes.

[0066] like Figure 1-11 As shown:

[0068] S1, adding the emulsion mixed with bacteria into the fermentation chamber through the adding pipe 202 for fermentation;

[0070] S3, when supplying oxygen, the transmission wheel 303 rotates, and then drives the tripod 302 to stir the emulsion through the middle tube 301, so that oxygen and the emulsion are fully in contact;

[0071] S4. After fermentation is completed, it is discharged through the discharge pipe 106.
