DETAILED DESCRIPTION

[0048] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0049] like Figures 1 to 10 As shown, a probiotic culture device according to the present invention includes a culture part, a control mechanism, a mounting mechanism, a removal mechanism and a stirring mechanism.

[0050] The culture part includes a fermentation tank 1 and a closing plate 2. A chamber for fermentation is arranged inside the fermentation tank 1. The upper opening of the fermentation tank 1 is closed by the closing plate 2. A sealing sheet is arranged on the bottom surface of the closing plate 2. After the material is put into the fermentation tank 1, the closing plate 2 is fixed to the upper end of the fermentation tank 1 by a screw to form a closed chamber to provide space for fermentation.

[0051] An observation window made of transparent glass is arranged on the side wall of the fermentation tank 1 .

[0052] The mounting mechanism comprises a mounting tube 9 and a supporting frame 8. The mounting tube 9 is fixedly mounted on the bottom of the closing plate 2. The closing plate 2 provides a mounting and force-carrying position for the mounting tube 9.

[0053] The support frame 8 is rotatably arranged on the bottom surface of the closing plate 2 , and an annular slide rail is arranged on the bottom surface of the closing plate 2 . The support frame 8 is slidably connected to the closing plate 2 via the annular slide rail.

[0054] The removal mechanism includes a cleaning plate 10 and a control cylinder 27. The cleaning plate 10 is fixedly mounted on the bottom end of the carrier frame 8 and supported by the carrier frame 8. After the material is injected, the bottom surface of the cleaning plate 10 is in contact with the liquid surface. The carrier frame 8 is rotated to control the cleaning plate 10 to scrape off the foam to achieve foam cleaning. A cavity is provided inside the cleaning plate 10. The air pressure in the inner cavity of the control cylinder 27 is adjusted to absorb the floating foam on the liquid inside the fermentation kettle 1 through the cleaning plate 10. The air pressure inside the control cylinder 27 is adjusted to be in a negative pressure state. After the negative pressure chamber is connected to the cleaning plate 10, the foam is absorbed, thereby improving the fermentation quality.

[0055] The stirring mechanism includes an air guide tube 13 and a guide block 28. The air guide tube 13 is unidirectionally connected to the inner cavity of the control cylinder 27, wherein one end of the air guide tube 13 extends to the bottom of the fermentation kettle 1, and the internal gas of the control cylinder 27 is discharged through the air guide tube 13. During the rising process of the bubbles, the material is disturbed to achieve stirring of the material, so that the material can be evenly mixed and fermented.

[0056] Among them, there are multiple air guide pipes 13 arranged in a ring shape, and multiple air guide pipes 13 are exhausted at the same time, which promotes the material to flow in a ring shape and improves the stirring efficiency. The guide block 28 is obliquely arranged at the exhaust end of the air guide pipe 13 to facilitate the gas to be discharged in an oblique upward direction, thereby forming an area for material flow, further improving the stirring and mixing efficiency.

[0057] The control mechanism is used to control the air pressure in the inner cavity of the control tube 27. By controlling the air pressure in the inner cavity of the control tube 27, the absorption of the foam and the stirring of the material are controlled at the same time.

[0058] As a preferred embodiment of the present invention, a partition for supporting the control cylinder 27 is provided in the mounting cylinder 9, and the inner cavity of the mounting cylinder 9 is divided into two upper and lower chambers by the partition. The lower chamber is used to store foam. After the foam enters the inner cavity of the control cylinder 27 through the cleaning plate 10, it flows to the bottom of the mounting cylinder 9 due to gravity, thereby realizing the storage of the foam.

[0059] A control piston 16 is slidably provided in the inner cavity of the control cylinder 27, and an intake check valve 18 and an exhaust check valve 17 are provided at the upper end of the control piston 16. The exhaust check valve 17 is connected to the air guide pipe 13. When the control piston 16 slides back and forth, air is introduced into the control cylinder 27 through the intake check valve 18, and exhaust is discharged into the fermentation kettle 1 through the exhaust check valve 17.

[0060] In the process of controlling the reciprocating sliding of the piston 16, the gas inside the fermentation kettle 1 is absorbed and then discharged into the inner cavity of the fermentation kettle 1. Compared with controlling the inner cavity of the fermentation kettle 1 by controlling the external gas through an external air pump, it can effectively prevent the external environment from polluting the internal materials of the fermentation kettle 1, thereby improving the quality of fermentation. At the same time, it can also realize the stirring of the material and the removal and collection of the foam, further improving the quality of the fermentation reaction.

[0061] One side of the cleaning plate 10 is tilted and has a through hole for foam to enter. The through hole inside the cleaning plate 10 is interconnected with the internal cavity of the cleaning plate 10, and a rubber diaphragm is provided at the connection position to control the flow direction of the foam to prevent the residual foam inside the cleaning plate 10 from flowing back into the inner cavity of the fermentation tank 1.

[0062] As a preferred embodiment of the present invention, a connecting pipe 11 is provided at the through hole of the cleaning plate 10. The connecting pipe 11 is a Y-shaped pipe for connecting multiple through holes. A connecting nozzle 12 for connecting to an intake check valve 18 is provided on one side of the connecting pipe 11, so as to absorb foam when the control piston 16 slides.

[0063] The bottom of the mounting cylinder 9 is detachably provided with a bottom plate 14, which is connected to the bottom of the mounting cylinder 9 by bolts. After the fermentation culture is completed, the foam stored inside the mounting cylinder 9 can be removed by removing the bottom plate 14 so that it can be used again.

[0064] In this embodiment, the control piston 16 is located in the control cylinder 27 and on the internal partition of the installation cylinder 9, so as to prevent the exhaust check valve 17 from exhausting the foam inside the installation cylinder 9 when exhausting.

[0065] A guide rod 15 is fixedly mounted in the inner cavity of the mounting tube 9 . The guide rod 15 is a hexagonal prism. A transmission plate 20 is slidably mounted on the outer wall of the guide rod 15 . The guide rod 15 provides a guide for the sliding of the transmission plate 20 .

[0066] The bottom of the transmission plate 20 is fixedly connected to the bottom surface of the control piston 16. A connecting rod is provided at the bottom of the transmission plate 20. The other end of the connecting rod is fixedly connected to the outer wall of the control piston 16. The sliding transmission plate 20 drives the control piston 16 to slide, thereby realizing the adjustment of the internal air pressure of the control cylinder 27.

[0067] As a preferred embodiment of the present invention, the control mechanism includes a control motor 3, a transmission shaft 25 and a transmission sleeve 19 fixedly connected to a transmission plate 20. The control motor 3 is a common servo motor. The transmission shaft 25 is rotatably installed in the inner cavity of the mounting cylinder 9, and the outer wall is provided with a reciprocating thread that cooperates with the transmission sleeve 19. The transmission sleeve 19 is sleeved on the outer wall of the transmission shaft 25. Rotating the transmission shaft 25 controls the transmission sleeve 19 to slide back and forth along the outer wall of the transmission shaft 25.

[0068] The control motor 3 is fixedly mounted on the upper end surface of the closing plate 2, and the output shaft of the control motor 3 is fixedly connected to the axial end of the transmission shaft 25, wherein the transmission shaft 25 passes through the closing plate 2, and a sealed bearing is provided at the connection position. The transmission shaft 25 is controlled to rotate by the control motor 3, thereby controlling the reciprocating sliding of the transmission sleeve 19 and the transmission plate 20.

[0069] As a preferred embodiment of the present invention, a connecting block 31 is fixedly installed at one end of the connecting tube 11, and the other end of the connecting block 31 is fixedly connected to the connecting nozzle 12. A control shaft 22 is rotatably installed in the inner cavity of the connecting block 31, and the control shaft 22 is connected to the connecting block 31 through a sealed bearing.

[0070] A connecting hole 21 is formed in the inner cavity of the control shaft 22 , and an extension tube 29 is fixedly mounted on the outer wall of the connection block 31 . The extension tube 29 extends upward and is always above the liquid level of the material in the fermentation kettle 1 .

[0071] The reciprocating sliding speed of the control piston 16 is proportional to the exhaust speed of the air duct 13. The faster the exhaust speed of the air duct 13, the higher the liquid level fluctuation of the liquid material inside the fermentation tank 1. The lower the exhaust speed of the air duct 13, the lower the liquid level fluctuation of the liquid material inside the fermentation tank 1.

[0072] When stirring the liquid inside the fermentation tank 1, the extension tube 29 is connected to the connecting nozzle 12 through the connecting hole 21. When stirring, it is necessary to increase the exhaust speed of the air duct 13 to improve the stirring efficiency. After the exhaust speed of the air duct 13 is increased, the control shaft 22 is rotated until the extension tube 29 is connected to the connecting hole 21. At this time, air is introduced through the extension tube 29 through the control cylinder 27, thereby preventing the material from entering the inner cavity of the mounting cylinder 9.

[0073] When absorbing the floating foam on the liquid inside the fermentation tank 1, the connecting pipe 11 is connected to the connecting nozzle 12 through the connecting hole 21. When removing the foam, in order to minimize the liquid level fluctuation that causes the cleaning plate 10 to absorb the material, it is necessary to reduce the exhaust speed of the air duct 13. After reducing the speed of the air duct 13, rotate the control shaft 22 until the connecting pipe 11 is connected to the connecting hole 21. At this time, the foam enters the interior of the control cylinder 27 through the cleaning plate 10.

[0074] A connecting piece 32 is fixedly mounted on the axial end of the control shaft 22 , and rotating the connecting piece 32 drives the control shaft 22 to rotate.

[0075] The bottom of the connecting piece 32 extends below the liquid level in the inner cavity of the fermentation kettle 1 and is fixedly installed with a sensing plate 30. The sensing plate 30 controls the deflection of the control shaft 22 by the rotation direction of the supporting frame 8. During the rotation of the supporting frame 8, the connecting block 31 is driven to rotate. Since the sensing plate 30 is located in the material, when the supporting frame 8 rotates, the sensing plate 30 is subjected to the resistance of the liquid, thereby pushing the direction of the deflection of the sensing plate 30.

[0076] During the deflection of the sensing plate 30, the control shaft 22 is driven to rotate through the connecting piece 32, thereby controlling the deflection of one end of the connecting hole 21. When the supporting frame 8 rotates forward, the sensing plate 30 deflects to control the extension tube 29 to be connected with the connecting hole 21. When the supporting frame 8 rotates reversely, the sensing plate 30 deflects to control the connecting tube 11 to be connected with the connecting hole 21.

[0077] As a preferred embodiment of the present invention, an adapter ring 4 is fixedly installed on the side wall of the carrier frame 8, an adapter plate 6 is rotatably provided on the bottom of the adapter ring 4, the adapter plate 6 is connected to the air intake check valve 18 through a conduit, and the adapter plate 6 is connected to the adapter ring 4 through a sealing bearing, thereby maintaining the connection between the connecting nozzle 12 and the air intake check valve 18 during the rotation of the carrier frame 8.

[0078] The upper end surface of the mounting cylinder 9 is rotatably mounted with the bearing cylinder 7, the inner wall of the bearing cylinder 7 is fixedly mounted with the transmission bevel block 5, the transmission shaft 25 passes through the bearing cylinder 7, and the outer wall is elastically mounted with a transmission bar 24 for engaging with the transmission bevel block 5, the transmission bar 24 is made of elastic material, the outer wall of the transmission bevel block 5 is inclined, when the transmission shaft 25 rotates forward, the transmission bar 24 and the transmission bevel block 5 slip, when the transmission shaft 25 rotates reversely, the transmission bar 24 pushes the transmission bevel block 5, thereby controlling the rotation of the bearing cylinder 7.

[0079] A transmission magnetic plate 23 is fixedly installed on the outer wall of the carrying cylinder 7, and a control magnetic plate 26 that attracts the transmission magnetic plate 23 is fixedly installed on the inner wall of the adapter ring 4. The magnetic poles of the transmission magnetic plate 23 and the control magnetic plate 26 that are close to each other are opposite. During the rotation of the carrying cylinder 7, the rotation of the adapter ring 4 is controlled by magnetic force.

[0080] When the transmission shaft 25 rotates forward, the carrier frame 8 remains stationary. When the transmission shaft 25 rotates reversely, it drives the carrier tube 7 to rotate. At this time, the adapter ring 4 and the carrier frame 8 are controlled to rotate, driving the cleaning plate 10 to rotate, scraping the foam to the outer wall of the cleaning plate 10, and cooperating with the negative pressure to achieve foam cleaning.

[0081] like Fig.11 As shown, a probiotics culture method, which uses the above-mentioned probiotics culture device, comprises the following steps:

[0082] A1, after injecting the material into the inner cavity of the fermentation tank 1, fix the sealing plate 2, and then detect the acidity, temperature and humidity values;

[0083] A2, by controlling the motor 3 to drive the control piston 16 to slide, control the air pipe 13 to exhaust, and stir the material;

[0084] A3, observing the liquid level inside the fermentation tank 1 through the observation window;

[0085] A4. When the foam needs to be cleaned, the motor 3 is controlled to rotate in the reverse direction, the cleaning plate 10 is controlled to scrape off the foam, and the foam is absorbed by the negative pressure.

[0086] The above-mentioned front, back, left, right, top and bottom are all based on the figures in the specification. Figure 1 As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
