Description

Technical Field

[0001] This invention belongs to the field of fruit and vegetable food fermentation and processing technology, and in particular relates to a fermentation device for prickly pear and gastrodia elata preserves. Background Technology

[0002] Gastrodia elata Bl. is the tuber of the orchid Gastrodia elata. It has the effects of calming the liver and extinguishing wind, dispelling wind and unblocking the meridians. As a traditional Chinese medicine, it was officially included in the list of substances that are both food and medicinal materials in November 2023. Studies have shown that Gastrodia elata has pharmacological effects such as anticonvulsant, analgesic, and sedative effects, and its active ingredients can promote sleep. Rosehip (Roserox burghii Tratt) is the fruit of the perennial deciduous shrub Rosehip in the Rosaceae family. It is one of the most distinctive and advantageous industries in Guizhou and a plant resource used for both food and medicine. It has a variety of excellent biological activities, and existing research shows that Rosehip has certain sedative and hypnotic effects. The core purpose of fermenting prickly pear and gastrodia elata preserves is to optimize the taste, enhance nutrition, extend shelf life, and create a unique flavor that caters to both snack and health needs.

[0003] Existing fermentation equipment requires sampling and monitoring during the fermentation process of prickly pear and gastrodia elata preserves. The purpose of this monitoring is to assess the sugar content (decreasing by 1-2°Bx every 24 hours), pH value (stabilizing at 3.2-3.5), and total bacterial count (≤10). 4 CFU / g); The existing methods for sampling fermentation broth in fermentation equipment mostly involve installing a drain valve at the bottom or side of the fermenter, opening the valve according to the sampling time set by the fermentation equipment, and then sampling and testing the fermentation broth inside the fermenter. Obviously, since the fermenter has a certain depth, and the fermentation broth is prone to stratification during fermentation, if each layer of fermentation broth is sampled and tested separately, the test data of the sampled fermentation broth is prone to large deviations, which will affect the testers' ability to monitor the fermentation status of the fermentation broth in the fermenter in real time. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a fermentation device for prickly pear and gastrodia elata preserves, comprising a fermentation tank with an inlet pipe and an outlet pipe connected to it, and a stirring assembly installed inside. An exhaust valve and a thermometer are installed on the top of the fermentation tank. The device also includes: a sampling tube fixedly installed inside the fermentation tank, with its lower end extending out of the bottom of the fermentation tank; multiple sampling ports along its length; several sealing components installed inside the sampling tube and corresponding to the multiple sampling ports; a support and conduction assembly connected to the upper and lower sealing components; and a drive conversion assembly, comprising a movable tube movably installed inside the sampling tube, multiple pressing blocks equidistantly installed along the length and circumference of the movable tube, and clamping blocks arranged on the sealing components. Under the drive rotation of the drive conversion assembly, the movable tube causes the multiple pressing blocks to sequentially align with the multiple clamping blocks. After the multiple pressing blocks align with the multiple abutting blocks sequentially from bottom to top, the moving tube slides downward under the drive of the driving conversion component, causing the multiple blocking components to open sequentially from bottom to top from the multiple sampling ports.

[0005] More specifically, the sealing assembly includes an annular groove formed on the inner wall of the sampling tube, a sealing cylinder movably installed in the annular groove, a docking guide hole formed on the sealing cylinder, a sealing ring installed at the upper and lower openings of the sealing cylinder, and a spring member connected to the bottom of the sealing cylinder and the bottom of the annular groove. The sealing ring located at the bottom of the sealing cylinder has a clamping block fixed at the inner ring opening, and the inside of the sealing ring is a sloping surface.

[0006] More specifically, the support and conduction assembly includes multiple support rings fixed inside the sampling tube, with each support ring located between two sealing cylinders, a connecting pipe fixed on the support ring, and an elastic hose connecting the port of the connecting pipe to the upper and lower sealing cylinders.

[0007] Further specifying, the drive conversion assembly also includes a support frame fixed to the legs of the fermenter, an electric push rod vertically mounted on the support frame, and a support plate connected to the output rod of the electric push rod; The lower opening of the moving tube rotates through a support plate via a bearing, and a motor is fixedly mounted on the support plate. The output shaft of the motor passes through the support plate and is connected to a drive gear. A driven gear that meshes with the drive gear is fixedly sleeved on the moving tube.

[0008] Further specified, the drive conversion assembly also includes an adjusting support rod vertically fixed to the bottom of the motor, a limiting ring fixed on the adjusting support rod, and an adjusting spring sleeved on the adjusting support rod and in contact with the limiting ring and the support frame; The lower half of the adjusting rod is threaded, and the adjusting rod extending below the support frame is fixedly connected by a nut.

[0009] Further specified, a flow guide plate is installed at the inner bottom of the sampling tube, the moving tube is movably connected to the flow guide plate through a sealing plug, and a collection tube is inclinedly connected to the bottom wall of the sampling tube, with the inner opening of the collection tube corresponding to the bottom of the flow guide plate.

[0010] More specifically, a plurality of stirring rods are installed on the wall of the moving tube located above the guide plate, and the plurality of stirring rods are all located below the sealing assembly at the bottom of the sampling tube.

[0011] Further specified, the wall of the movable pipe is provided with water spray holes along its length, the upper opening of the movable pipe is in a blocked state, and the lower opening of the movable pipe is rotatably connected to a water injection hose.

[0012] The present invention has the following beneficial effects: The fermentation broth in the fermenter flows into the sampling tube through sampling ports that open sequentially from bottom to top. The fermentation broth flowing into each sampling port is concentrated in the same sampling tube and does not need to be discharged separately. This allows the fermentation broth flowing in in layers to not only flush the liquid flowing in from the previous layer, but also to disperse and mix with the fermentation broth flowing into the bottom of the sampling tube. This allows the fermentation broth in the fermenter to be sampled in layers and then mixed before being discharged, thereby improving the accuracy and efficiency of the sampling and testing of the fermentation broth in the fermenter. Since the fermentation broth after stratified sampling needs to flow into the same sampling tube for mixing, it is not necessary to install multiple sets of sampling conduits and drainage pipes corresponding to the sampling ports in the sampling tube. This not only reduces the complexity of assembling the sampling mechanism in the fermenter, but also does not take up much space. Since multiple sampling ports are independently sealed by multiple sets of sealing components, and then through the cooperation of the moving tube and the drive conversion component, one sampling port can be opened individually for sampling. This not only facilitates the detection of fermentation sediment in the fermenter, but also enables individual sampling and monitoring of fermentation liquid in different layers of the fermenter, making it easier for operators to accurately observe the fermentation status of the fermentation liquid.

[0013] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0019] Please see Figures 1-6As shown, this invention is a fermentation device for prickly pear and gastrodia elata fruit preserves, including a fermentation tank 1, with an inlet pipe and an outlet pipe connected to the fermentation tank 1, and a stirring assembly 2 installed inside it. An exhaust valve and a thermometer are installed on the top of the fermentation tank 1. It also includes: a sampling tube 3, fixedly installed inside the fermentation tank 1, with its lower end extending out of the bottom of the fermentation tank 1; multiple sampling ports 31 along its length of the sampling tube 3; several sealing assemblies 4, installed inside the sampling tube 3 and corresponding to the multiple sampling ports 31; a supporting and conductive assembly 5, connected to the upper and lower sealing assemblies 4; and a driving and conversion assembly 6. The moving conversion component 6 includes a movable tube 61 movably installed inside the sampling tube 3, a plurality of pressing blocks 62 equidistantly installed along the length and circumference of the movable tube 61, and abutting blocks 63 arranged on a plurality of sealing components 4; the movable tube 61, driven by the driving conversion component 6, causes the plurality of pressing blocks 62 to align sequentially with the plurality of abutting blocks 63; after the plurality of pressing blocks 62 are aligned sequentially with the plurality of abutting blocks 63 from bottom to top, the movable tube 61, driven by the driving conversion component 6, slides downward, causing the plurality of sealing components 4 to open sequentially from bottom to top from the plurality of sampling ports 31; In a preferred embodiment of the present invention, the sampling tube 3 is vertically fixed inside the fermentation tank 1 without interfering with the normal stirring of the fermentation liquid in the fermentation tank 1 by the stirring component 2, so that the length of the sampling tube 3 extends into the fermentation tank 1 to more than two-thirds of the interior. The connection between the sampling tube 3 and the tank body of the fermentation tank 1 is sealed by welding or other means to prevent leakage of the fermentation tank 1. The number of sampling ports 31 is determined according to the length of the sampling tube 3 inserted into the fermentation tank 1. Taking the preferred three sampling ports 31 in this scheme as an example, the same sealing component 4 is also set to three sets. The projections of the three pressing blocks 62 arranged in a circular array along the length of the moving tube 61 are on the same annular surface. The specific working process of the fermentation equipment of the present invention is as follows: First, feed the prickly pear pulp and gastrodia elata granules into fermenter 1 through the feed pipe, add white sugar, honey, and sterile water, and stir for 15-20 minutes using stirring component 2 until the sugar is completely dissolved. Adjust the pH to 3.2-3.5 with sodium citrate, and monitor the saccharimeter to 20-22°Bx in real time. Then, pump the activated fermentation agent into fermenter 1 through sterile pipeline, with an inoculum amount of 0.05%-0.1% (based on the total mass of the fermentation liquid). Turn on the variable frequency stirrer (30 r / min) and stir for 10-12 minutes to ensure that the strain and raw materials are in full contact. Second, constant temperature circulating water is introduced into the double-layer jacket of fermenter 1 to control the temperature inside the tank at 26±1℃ (the optimal fermentation temperature, which increases fermentation efficiency by 40% compared to room temperature). The entire process is automatically monitored, and the temperature difference does not exceed ±1℃. Stirring and degassing: Stir intermittently with stirring component 2 during the first two days (3-5 times a day, 10-12 minutes each time) to promote flavor integration; an automatic degassing valve is installed on the top of fermentation tank 1 (automatic degassing when the pressure is ≥0.02MPa) to prevent gas from causing contamination inside fermentation tank 1; When sampling is required at a predetermined time (e.g., 8-hour sampling and testing), take multi-layer sampling and mixing as an example: ① Bottom-level sampling: First, control the drive conversion component 6 to drive the moving tube 61 to rotate within the sampling tube 3. This causes the lowermost pressing block 62 of the moving tube 61 to align with the uppermost pressing block 63 of the sealing component 4 within the sampling tube 3. At this point, the two pressing blocks 62 above the moving tube 61 are offset from the pressing blocks 63 of the other two sets of sealing components 4. Then, drive the moving tube 61 to descend within the sampling tube 3 via the drive conversion component 6, causing it to move through the pressing blocks 62 and pressing blocks 63, thus aligning the sealing component 4 with the sampling tube. The sample tube 3 moves downward, so that the sampling port 31 at the bottom of the sampling tube 3 opens first, which facilitates the sediment (Gastrodia elata granules, etc.) in the fermentation liquid at the bottom of the fermenter 1 to enter the sampling tube 3 first. After a certain amount of the bottom fermentation liquid is sampled (depending on the opening time of the sampling port 31 or the liquid level sensor installed at the bottom of the sampling tube 3), the moving tube 61 is driven to rise in the sampling tube 3 by the drive conversion component 6, so that the aligned pressing block 62 is released from the pressure on the pressing block 63, and the sealing component 4 will seal the opened sampling port 31. ② Mid-layer sampling: After the bottom layer sampling is completed and the bottom layer sealing component 4 is reset, the drive conversion component 6 continues to work, causing the moving tube 61 to continue rotating a certain angle within the sampling tube 3. The lowering block 62 in the middle of the moving tube 61 rotates to align with the clamping block 63 installed in the sealing component 4 in the middle of the sampling tube 3. At this time, the lowering blocks 62 at the bottom and top of the moving tube 61 are disaligned with the upper and lower clamping blocks 63. The drive conversion component 6 then continues to drive the moving tube 61 to descend within the sampling tube 3, causing it to open the sealing component 4 in the middle of the sampling tube 3 through the lowering block 62 and the aligned clamping block 63. This facilitates the opening of the sampling port 31 in the middle of the sampling tube 3. The fermentation liquid in the middle layer of the fermenter 1 can enter the sampling tube 3 through the open sampling port 31. The upper and lower sealing components 4 are connected by the support and conduction components 5. Therefore, the fermentation liquid that enters the sampling tube 3 through the middle sampling port 31 can fall into the lower sealing component 4 through the support and conduction components 5, so that it can be flushed down by the bottom fermentation liquid remaining in the lower sealing component 4 to the bottom of the sampling tube 3. After a certain amount of fermentation liquid is extracted by the middle sampling port 31, the moving tube 61 is controlled to rise in the sampling tube 3, so that the middle pressing block 62 is released from the pressure of the aligned pressing block 63, and the sealing component 4 in the middle of the sampling tube 3 seals the middle open sampling port 31. ③ Top layer sampling: After the middle layer sampling is completed and the sampling port 31 in the middle is blocked, the drive conversion component 6 is operated again to continue to rotate, so that the moving tube 61 continues to rotate in the same direction at a certain angle in the sampling tube 3, so that the pressing block 62 of the top layer is aligned with the pressing block 63 in the sealing component 4 of the top layer of the sampling tube 3, and then the moving tube 61 is fully lowered, so that the sealing component 4 of the top layer opens the aligned sampling port 31, so that the fermentation liquid of the top layer of the fermenter 1 can enter the sampling tube 3 through the opened sampling port 31 of the top layer, so that the fermentation liquid flowing in from the top layer can flush the fermentation liquid sampled in the middle and bottom of the sampling tube 3. After the fermentation liquid of the top layer is sampled, the sealing component 4 of the top layer is sealed to the sampling port 31 to achieve three-layer sampling of the fermentation liquid in the fermenter 1. ④ Sampling and mixing: During the stratified sampling of the fermentation broth in sampling tube 3, the valve on the collection tube 8 at the bottom of sampling tube 3 remains closed. This allows the fermentation broth flowing from bottom to top into sampling tube 3 to fall and accumulate at the bottom. The continuously flowing fermentation broth then initially flushes and agitates the accumulated broth at the bottom of sampling tube 3, enabling preliminary mixing of the collected multi-layered fermentation broth at the bottom of sampling tube 3. The mixed fermentation broth is then discharged into a sample bottle through the open collection tube 8 for testing. The tests are conducted to determine the sugar content (decreases by 1-2°Bx every 24 hours), pH value (stable at 3.2-3.5), and total bacterial count (≤10). 4 If the sugar content decreases slowly (CFU / g), add 0.02% starter culture. Terminating fermentation: Fermentation can be terminated when the sugar content drops to 8-10°Bx, the amount of bubbles in the tank decreases by 80%, and the Gastrodia elata granules sink (total fermentation time 4-5 days). Cooling (below 10℃) inhibits bacterial activity. The amount of Gastrodia elata granules sinking can also be determined by sampling, for example: By driving the conversion component 6, the moving tube 61 is driven to rotate inside the sampling tube 3, so that the bottom pressing block 62 rotates to align with the pressing block 63 on the bottom sealing component 4. Then, the moving tube 61 is driven to descend inside the sampling tube 3, so that the sealing component 4 near the bottom of the sampling tube 3 opens from the sampling port 31. This facilitates the sedimentation of Gastrodia elata particles from the bottom of the fermenter 1, which will flow into the sampling tube 3 and then be discharged into the sample bottle for testing through the opened collection tube 8. The present invention features a vertical sampling tube 3 fixedly installed inside a fermenter 1. The sampling tube 3 has sampling ports 31 evenly spaced within it, which are sealed by a sealing assembly 4. The movable tube 61 can rotate and then move up and down within the sampling tube 3 via a drive conversion assembly 6. The beneficial effects are as follows: The fermentation broth in fermenter 1 flows into sampling tube 3 through sampling ports 31 that open sequentially from bottom to top. The fermentation broth flowing into each sampling port 31 is concentrated in the same sampling tube 3, without needing to be discharged separately. This allows the fermentation broth flowing in in layers to not only flush the liquid flowing in from the previous layer, but also to disperse and mix with the fermentation broth flowing to the bottom of sampling tube 3. This allows the fermentation broth in fermenter 1 to be sampled in layers and then mixed before being discharged, thereby improving the accuracy and efficiency of the sampling and testing of the fermentation broth in fermenter 1. Since the fermentation broth after stratified sampling needs to flow into the same sampling tube 3 for mixing, it is not necessary to install multiple sets of sampling conduits and drainage pipes corresponding to the sampling port 31 in the sampling tube 3. This not only reduces the complexity of the sampling mechanism assembly in the fermenter 1, but also does not take up much space. Since the multiple sampling ports 31 are independently sealed by multiple sets of sealing components 4, and then through the cooperation of the moving tube 61 and the drive conversion component 6, one of the sampling ports 31 can be opened for individual sampling. This not only facilitates the detection of fermentation sediment in the fermenter 1, but also enables individual sampling and monitoring of fermentation liquid in different layers of the fermenter 1, making it easier for operators to accurately observe the fermentation status of the fermentation liquid.

[0020] See Figure 3 and Figure 4 As shown, the sealing assembly 4 includes an annular groove 41 formed on the inner wall of the sampling tube 3, a sealing cylinder 42 movably installed in the annular groove 41, a docking guide hole 43 formed on the sealing cylinder 42, a sealing ring 44 installed at the upper and lower openings of the sealing cylinder 42, and a spring member 45 connected to the bottom of the sealing cylinder 42 and the bottom of the annular groove 41; wherein, a clamping block 63 is fixed at the inner opening of the sealing ring 44 located at the bottom of the sealing cylinder 42, and the inside of the sealing ring 44 is a sloping surface; In a preferred embodiment of the present invention, the bottoms of the three sets of sealing cylinders 42, which are equidistantly arranged in the height direction inside the sampling tube 3, are mounted on the clamping blocks 63, which are also arranged in a circumferential array in the height space, and the three clamping blocks 63 are also projected onto the same annular surface; the height of the sealing cylinder 42 is greater than the groove height of the sampling port 31, and the connecting guide hole 43 is on the same axis as the sampling port 31, and the size of the clamping block 63 is much smaller than the size of the annular hole of the sealing ring 44, so that it will not interfere with the normal flow of the fermentation liquid; When the moving tube 61 rotates inside the sampling tube 3, the lower pressure block 62 rotates to align with the upper clamping block 63. At this time, the moving tube 61 descends inside the sampling tube 3. The contact between the lower pressure block 62 and the clamping block 63 drives the sealing cylinder 42 to descend in the annular groove 41, aligning the docking guide hole 43 with the sampling port 31. At this time, the sealing ring 44 located below will squeeze the spring 45, compressing the spring 45 in the annular groove 41. When the docking guide hole 43 aligns with the sampling port 31, the fermentation liquid in the fermenter 1 will enter the sealing cylinder 42 through the sampling port 31 and the docking guide hole 43. Since the upper opening of the sealing cylinder 42 is also connected to the support and conduction assembly 5 through the sealing ring 44, the fermentation liquid entering the sealing cylinder 42 will fall to the bottom of the sampling tube 3 for mixing and discharge. When a certain amount of fermentation liquid enters the sampling port 31, the moving tube 61 moves upward in the sampling tube 3, causing the pressing block 62 to disengage from the pressing block 63. Then, the sealing cylinder 42 moves upward in the annular groove 41 under the push of the elastic restoring force of the spring 45, so that the docking guide hole 43 is misaligned with the sampling port 31, thus facilitating the sealing cylinder 42 to seal the sampling port 31 opened on the sampling tube 3. When the moving tube 61 rotates again inside the sampling tube 3, the already aligned pressing block 62 and the clamping block 63 will be misaligned, while the upper pressing block 62 will be aligned with the clamping block 63. As a result, when the moving tube 61 moves down inside the sampling tube 3 again, the misaligned pressing block 62 will move freely down inside the sealing cylinder 42 without pushing the misaligned clamping block 63, thus facilitating the sealing cylinder 42 to always seal the sampling port 31.

[0021] See Figures 3 to 5 As shown, the support and conduction assembly 5 includes multiple support rings 51 fixed inside the sampling tube 3, and each support ring 51 is located between two sealing cylinders 42, a connecting pipe 52 fixed on the support ring 51, and an elastic hose 53 connecting the port of the connecting pipe 52 to the upper and lower sealing cylinders 42. In a preferred embodiment of the present invention, the compression and stretching of the elastic hose 53 are both greater than the sliding distance of the sealing cylinder 42 in the annular groove 41, while the support ring 51 is fixed on the wall of the sampling tube 3 between the upper and lower sealing cylinders 42. When the sealing cylinder 42 slides downward in the annular groove 41, the elastic hose 53 located below the sealing cylinder 42 will be compressed, while the elastic hose 53 located above will be stretched. The connecting pipes 52 fixed on the upper and lower sides of the sealing cylinder 42 will limit and support the stretched and compressed elastic hoses 53, preventing the phenomenon that when one sealing cylinder 42 moves up and down in the annular groove 41, the stretching or compression of the elastic hoses 53 will cause other sealing cylinders 42 to slide down or rise synchronously in the annular groove 41, which will affect the precise sealing of other sampling ports 31 by other sealing cylinders 42. It can also prevent interference caused by the rigid connection between two adjacent sealing cylinders 42 when one of the sealing cylinders 42 slides downward or rises, which would lead to the sealing cylinder 42 that needs to be opened being unable to slide accurately open or seal within the annular groove 41.

[0022] See Figures 3 to 6 As shown, the drive conversion assembly 6 also includes a support frame 64 fixed on the legs of the fermenter 1, an electric push rod 65 vertically mounted on the support frame 64, and a support plate 66 connected to the output rod of the electric push rod 65. The lower opening of the moving tube 61 rotates through the support plate 66 via a bearing, and a motor is fixed on the support plate 66. The output shaft of the motor passes through the support plate 66 and is connected to the drive gear 67. A driven gear 68 that meshes with the drive gear 67 is fixedly sleeved on the moving tube 61. In a preferred embodiment of the present invention, the support frame 64 is fixed to the support leg by welding, and the cylinder and output rod of the electric push rod 65 are fixed to the support frame 64 and the support plate 66 by screws. The driven gear 68 needs to be installed on the moving tube 61 first, and then the moving tube 61 is rotated through the support plate 66 by bearing. The motor is preferably a self-locking motor. Therefore, when the moving tube 61 needs to rotate inside the sampling tube 3, the motor needs to be controlled to work so that it can drive the moving tube 61 to rotate a certain angle inside the sampling tube 3 through the meshing of the driving gear 67 and the driven gear 68. The rotation angle of the moving tube 61 needs to be matched with the circumferential distance between the upper and lower pressing blocks 62 fixedly installed on the moving tube 61 so that when the moving tube 61 drives one of the pressing blocks 62 to rotate and align with one of the clamping blocks 63, the other sets of pressing blocks 62 and clamping blocks 63 are in a disaligned state. Then, control the output rod of the electric push rod 65 to retract, so that it drives the moving tube 61 to descend vertically in the sampling tube 3 through the support plate 66. At this time, the motor, the driving gear 67 and the driven gear 68 will move down synchronously, so that the moving tube 61 will drive the pressing block 63 to descend vertically in the sampling tube 3 through the pressing block 62, which makes it easier to open the sealing cylinder 42 from the sampling port 31. When a certain amount of fermentation liquid is collected in the sampling tube 3, the output rod of the electric push rod 65 will extend, causing the moving tube 61 to rise vertically in the sampling tube 3, thereby causing the lower pressure block 62 to disengage from the pressing block 63. The sealing cylinder 42 will seal the sampling port 31 by being pushed and reset by the spring element 45. When the next set of pressing blocks 62 and clamping blocks 63 need to be aligned, the moving tube 61 can be driven to rotate around the same direction by the same angle, so that the previous set of pressing blocks 62 and clamping blocks 63 are disaligned, and the new set of pressing blocks 62 and clamping blocks 63 are aligned, which makes it easier to open the sealing cylinder 42 from the sampling port 31.

[0023] See Figure 6 As shown, the drive conversion assembly 6 also includes an adjusting support rod 69 vertically fixed to the bottom of the motor, a limiting ring 691 fixed on the adjusting support rod 69, and an adjusting spring 692 sleeved on the adjusting support rod 69 and in contact with the limiting ring 691 and the support frame 64. The lower half of the adjusting rod 69 is threaded, so that the adjusting rod 69 extending below the support frame 64 is fixedly connected by a nut. As a preferred embodiment of the present invention, in order to enable the moving tube 61 to move up and down accurately within the sampling tube 3, this solution provides an adjustable support rod 69 that can be raised and lowered on the other side of the electric push rod 65. The top part of the adjustable support rod 69 is fixed to the motor housing, and its lower half threaded rod moves through the support frame 64. Therefore, when the support plate 66 descends vertically, the adjusting rod 69 slides down on the support frame 64. At this time, the adjusting spring 692, which is limited by the limiting ring 691 and the support frame 64, is compressed, so that the sliding adjusting rod 69 can provide sliding support for the support plate 66. This prevents the structural components installed on the support plate 66 from directly impacting the electric push rod 65, which could easily lead to damage to the electric push rod 65 or cause the vertically rising and falling support plate 66 to become skewed. When the support plate 66 moves upward, the elastic restoring force of the adjusting spring 692 will push the support plate 66 upward, which will in turn assist the electric push rod 65 to move, so that the moving tube 61 can be accurately raised and lowered vertically within the sampling tube 3.

[0024] See Figure 6 As shown, a guide plate 7 is installed at the bottom of the sampling tube 3, and the moving tube 61 is movably connected to the guide plate 7 through a sealing plug. The bottom wall of the sampling tube 3 is inclined to connect to a collection tube 8, and the inner opening of the collection tube 8 corresponds to the bottom of the guide plate 7. Furthermore, multiple stirring rods 9 are installed on the wall of the moving tube 61 located above the guide plate 7, and the multiple stirring rods 9 are all located below the sealing assembly 4 at the bottom inside the sampling tube 3. As a preferred embodiment of the present invention, the moving tube 61 is connected to the guide plate 7 through a sealing plug, so that the moving tube 61 can rotate in the sampling tube 3 and rise and fall in the sampling tube 3, and will not cause the fermentation liquid falling on the guide plate 7 to leak. When the three sampling ports 31 are opened in sequence, allowing the fermentation broth to flow into the sampling tube 3 and be positioned above the guide plate 7, the motor can be controlled to rotate the moving tube 61 around the sampling tube 3. This allows multiple stirring rods 9 to stir the sampled fermentation broth, ensuring thorough and rapid mixing of the multi-layered sampled fermentation broth. Then, the mouth of the sampling bottle is aligned with the mouth of the collection tube 8, and the valve on the collection tube 8 is opened, allowing the fermentation broth stirred in the sampling tube 3 to flow into the sampling bottle. The mixed fermentation broth can be collected through multiple sampling bottles, increasing the accuracy of the fermentation broth detection in the fermenter 1.

[0025] See Figure 5 and Figure 6 As shown, the wall of the movable pipe 61 is provided with a water spray hole 611 along its length direction. The upper opening of the movable pipe 61 is in a blocked state, while the lower opening of the movable pipe 61 is rotatably connected to a water injection hose 10. As a preferred embodiment of the present invention, the water spray holes 611 can be opened in multiple groups, and the distance between the upper and lower groups of water spray holes 611 is similar to the height of the sealing cylinder 42. The water spray holes 611 can also be atomizing holes or fine holes. Therefore, when the sealing cylinder 42 moves down normally, opening the sampling port 31, the fermentation liquid enters the sealing cylinder 42 through the sampling port 31 and the connecting guide hole 43. At this time, the water spray hole 611 opened on the moving tube 61 faces away from the sampling port 31, and each group of multiple water spray holes 611 will be located inside the connecting tube 52. This prevents the fermentation liquid entering the sealing cylinder 42 from entering the moving tube 61 in large quantities through the water spray hole 611, thus causing a large amount of waste of the sampled fermentation liquid. After the fermentation broth is discharged through the collection tube 8, the multiple sampling ports 31 will be sealed. Then, the operator can inject sterile water into the moving tube 61 through the water injection hose 10, and then drive the moving tube 61 to rotate and rise and fall inside the sampling tube 3, so that the sterile water sprayed by the water spray hole 611 can fully sterilely clean the sampling tube 3 and the structure inside the sampling tube 3 that comes into contact with the fermentation broth. The cleaned water will be discharged through the collection tube 8. After the sampling tube 3 is sterilely cleaned, a sterile hot air stream can be introduced through the water injection hose 10 to dry the moving tube 61, the sampling tube 3 and the internal structural components, so that the sampling tube 3 can be used to sample the fermentation broth again.
