[0002] In the process of producing biological feed, large-scale fermentation is usually carried out in a fermentation tank. In order to ensure the normal progress of fermentation, samples are usually taken for analysis during the fermentation process, and the fermentation conditions are regulated according to the analysis results, for example, refer to CN118310921A, CN216309920U, CN211856491U. In the current process, sampling is usually carried out at a fixed point, which cannot comprehensively analyze the fermentation situation in the fermentation tank, which is not conducive to accurately regulating the fermentation conditions. Summary of the invention

[0003] The purpose of the present application is to provide a biological feed fermentation process analysis system and a biological feed fermentation optimization method, which can controllably perform sampling at different preset depths, which is conducive to more comprehensive analysis of the fermentation situation and more accurate regulation of the fermentation conditions.

[0004] The embodiment of the present application is implemented as follows:

[0005] In a first aspect, an embodiment of the present application provides a biological feed fermentation process analysis system, comprising: a sampling tube body, a sliding sleeve, a sampling assembly and a driving mechanism;

[0006] The sampling tube body comprises a sliding tube section and an analysis tube section which are interconnected, and a sampling window is provided on the tube wall of the analysis tube section;

The sliding rod is slidably arranged in the first core body along the axial direction of the sampling tube body, and the extrusion plate is located on the side of the first core body away from the supporting plate. When the sampling assembly is located at the analysis position, the sliding rod is supported by the supporting plate, and the extrusion plate is slidably sealed with the inner side of the tube wall of the sampling tube body and the partition respectively, so that when the sampling assembly moves from the analysis position to the extrusion position, the extrusion plate gradually moves away from the first core body, and when the sampling assembly moves from the extrusion position to the analysis position, the extrusion plate gradually approaches the first core body.

[0015] In some embodiments, when the sampling assembly is located at the analysis position, the extrusion plate is magnetically attached to the first core, and the slide rod is magnetically attached to the support plate.

[0016] In some embodiments, the sampling assembly further includes a water absorbing layer, which is detachably connected to the extrusion plate, and the extrusion plate is provided with a through hole extending through the axial direction of the sampling tube body;

[0017] Among them, on the side close to the first core body, the tube wall of the analysis tube section is also provided with a water absorption sampling operation window and a gas sampling port.

[0020] In some embodiments, the end of the analysis tube section away from the sliding tube section has an end plate, an elastic recovery member is provided between the end plate and the supporting plate, and the end of the partition can be slidably passed through the supporting plate and connected to the elastic recovery member; when the sampling assembly is located in the analysis position, the elastic recovery member is in a natural state; when the sampling assembly is located in the extrusion position, the elastic recovery member is in an elastically deformed state.

[0021] In some embodiments, the inner wall of the analysis tube section is provided with a sliding groove extending axially along the sampling tube body, and the edge of the partition is slidably sealed with the sliding groove; when the sampling assembly is in the analysis position, the partition is pressed against the side wall of the sliding groove close to the sliding tube section.

[0022] In some embodiments, when the sampling assembly is in the sampling position, the control core is located on the inner side of the end of the sliding tube section away from the analysis tube section.

[0024] Among them, the biological feed fermentation process analysis system is connected to the sampling port of the fermentation tank through a sliding sleeve. The fermentation analysis includes:

[0025] The position of the control core is adjusted to place the sampling assembly at the analysis position; then the sliding tube section is driven to slide relative to the sliding sleeve so that the end of the sliding tube section extends into a preset depth position in the fermentation tank;

[0026] Then, the position of the control core is adjusted to move the sampling assembly to the sampling position, so that the fermented feed at the preset depth position is filled into the feed containing channel;

[0027] The position of the control core is then adjusted to return the sampling assembly to the analysis position, so that the fermented feed in the feed containing channel is pushed into the position corresponding to the sampling window in the sampling tube body;

[0028] Take samples from the sampling window for analysis.

[0029] The biological feed fermentation process analysis system and biological feed fermentation optimization method provided in the embodiments of the present application include the following beneficial effects:

[0030] In an embodiment of the present application, the sampling tube body is connected to the fermentation tank via a sliding sleeve; the sliding tube section of the sampling tube body slides relative to the sliding sleeve to extend the sampling tube body to different preset depth positions of the fermentation tank, thereby enabling sampling at different preset depth positions of the fermentation tank, which is conducive to more comprehensive analysis of the fermentation situation and more accurate regulation of the fermentation conditions.

[0031] In the design of the sampling function structure, a push rod is arranged at the front end of the sampling component, and a control core is arranged at the rear end of the sampling component. The push rod and the control core are used to enclose a feed containing channel between the two; the control core is driven by a driving mechanism to move relative to the sampling tube body, thereby driving the sampling component to reciprocate between the sampling position and the analysis position. When the sampling component moves to the sampling position, the fermented feed at the preset depth position of the fermentation tank is filled into the feed containing channel; when the sampling component moves back to the analysis position, the fermented feed in the feed containing channel is brought back into the sampling tube body. Among them, when the sampling component is located at the analysis position, the push rod and the inner side of the tube wall of the sampling tube body can be slidably sealed and matched. On the one hand, before the sampling tube body extends to the preset depth position, the fermented feed in the fermentation tank is prevented from entering the feed containing channel in advance; on the other hand, the control core and the inner side of the tube wall of the sampling tube body can be slidably sealed and matched. After the sampling is completed, the fermented feed in the feed containing channel can be better sealed in the sampling tube body, which is conducive to more accurate and controllable sampling and analysis at different preset depth positions.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0058] The technical solution of the present application will be exemplarily described below through some embodiments.

[0059] See also Figure 1 In the first aspect, the embodiment of the present application provides a biological feed fermentation process analysis system 100, which is exemplarily connected to a fermentation tank 200 for application. As an example, the biological feed fermentation process analysis system 100 is connected to a sampling port on the side wall of the fermentation tank 200. Based on this, multiple biological feed fermentation process analysis systems 100 can be distributed at intervals along the height direction of the fermentation tank 200, so as to facilitate sampling and analysis at different heights.

[0060] See also Figure 2 The biological feed fermentation process analysis system 100 includes: a sampling tube body 110 , a sliding sleeve 120 , a sampling component 130 and a driving mechanism 140 .

[0061] The sampling tube body 110 includes a sliding tube section 111 and an analysis tube section 112 which are interconnected. A sampling window (not shown) is provided on the tube wall of the analysis tube section 112. The sliding sleeve 120 is slidably and sealingly sleeved on the outer side of the tube wall of the sliding tube section 111 along the axial direction of the sampling tube body 110.

[0062] It can be understood that the sampling window is a window that can be opened and closed for solid-state fermentation feed sampling, and it is connected to the accommodating cavity inside the sampling tube body 110; the sampling window can be designed in a conventional manner, such as but not limited to connecting the window door by snap-fitting, threaded connection, etc. to achieve opening and closing.

[0063] It should be noted that the sliding pipe section 111 and the analysis pipe section 112 can be integrally connected pipe sections or detachably sealed pipe sections; the sliding pipe section 111 and the analysis pipe section 112 can be made of the same material or different materials. As an example, the sliding pipe section 111 is made of alloy and other materials, which has good strength and is convenient for more stable cooperation with the sealing sleeve; the analysis pipe section 112 is made of transparent materials such as polymer plastics, which is convenient for observing the internal situation; based on this, the sliding pipe section 111 and the analysis pipe section 112 are detachably sealed and connected through a connecting joint.

[0064] In addition, the sliding pipe section 111 can be designed with sliding structures such as sliding blocks and sliding grooves as needed, so as to better perform slidable sealing cooperation with the sliding sleeve 120 .

[0065] In an embodiment of the present application, the sampling tube body 110 is connected to the fermentation tank 200 through a sliding sleeve 120; the sliding tube section 111 of the sampling tube body 110 slides relative to the sliding sleeve 120, so that the sampling tube body 110 can be extended to different preset depths of the fermentation tank 200, thereby being able to sample at different preset depths of the fermentation tank 200, which is conducive to more comprehensive analysis of the fermentation situation and more accurate regulation of the fermentation conditions.

[0066] See also Figure 2~Figure 6 The sampling assembly 130 includes a push rod 131, a connector 132 and a control core 133 which are sequentially connected along the axial direction of the sampling tube body 110, and a feed containing channel 134 corresponding to the connector 132 is provided between the push rod 131 and the control core 133.

[0067] It can be understood that there is a feed containing channel 134 between the push rod 131 and the control core 133, which means that the outer contour size of the connecting piece 132 is smaller than the outer contour size of the push rod 131 and the control core 133, so that there is a cavity between the push rod 131 and the control core 133.

[0068] The control core 133 is slidably sealed with the inner side of the tube wall of the sampling tube body 110, so that the sampling assembly 130 can reciprocate between the sampling position and the analysis position along the axial direction of the sampling tube body 110. The driving mechanism 140 is connected to the control core 133 in a transmission manner, and is used to drive the control core 133 to move along the axial direction of the sampling tube body 110, thereby driving the sampling assembly 130 to reciprocate between the sampling position and the analysis position. In the embodiment of the present application, the motion stroke control of the sampling assembly 130 can be achieved by controlling the driving stroke of the control core 133 by the driving mechanism 140; wherein the sampling assembly 130 is not limited to being able to reciprocate between the sampling position and the analysis position.

[0069] It should be noted that the design of the driving mechanism 140 is not limited; for example, a driving rod extending out of the sampling tube body 110 may be provided, and then the sampling tube body 110 may be driven manually or by the driver outputting power; for another example, a driver may be provided inside the sampling tube body 110, and the power output end of the driver may be directly connected to the control core 133. As an example, the driving mechanism 140 includes a driving rod extending along the axial direction of the sampling tube body 110, one end of the driving rod is connected to the control core 133, and the other end of the driving rod extends from the end of the analysis tube section 112 out of the sampling tube body 110 as a driving end.

[0070] See also Figure 3 and Figure 4 When the sampling assembly 130 is located at the analysis position, the push rod 131 is slidably sealed with the inner side of the tube wall of the sampling tube body 110, and the connecting piece 132 corresponds to the sampling window, that is, the feed containing channel 134 corresponds to the sampling window.

[0071] As an example, when the sampling assembly 130 is located at the analysis position, the push rod 131 is located on the inner side of the end of the sliding tube segment 111 away from the analysis tube segment 112, and the end of the push rod 131 corresponds to the end of the sliding tube segment 111; based on this design, the fermented feed in the fermentation tank 200 is prevented from entering the inner cavity at the end of the sliding tube segment 111.

[0072] See also Figure 5 and Figure 6 When the sampling assembly 130 is located at the sampling position, the push rod 131 and the connecting piece 132 both extend out of the sampling tube body 110 from the end of the sliding tube section 111; it can be understood that the end of the sliding tube section 111 refers to the end of the sliding tube section 111 away from the analysis tube section 112.

[0073] As an example, when the sampling assembly 130 is located at the sampling position, the control core 133 is located on the inner side of the end of the sliding tube segment 111 away from the analysis tube segment 112; based on this design, the end of the sliding tube segment 111 is sealed to prevent the fermented feed in the fermentation tank 200 from entering the side of the control core 133 close to the analysis tube segment 112.

[0074] Since the fermented feed in the fermentation tank 200 is mainly in solid form, optionally, the push rod 131 has a conical protrusion at one end away from the connecting piece 132. Based on this design, when the sampling assembly 130 moves from the analysis position to the sampling position, it is helpful to push the fermented feed in the fermentation tank 200 and move forward.

[0075] In the embodiment of the present application, a push rod 131 is arranged at the front end of the sampling assembly 130, and a control core 133 is arranged at the rear end of the sampling assembly 130. The push rod 131 and the control core 133 form a feed receiving channel 134 between the two. The control core 133 is driven by the driving mechanism 140 to move relative to the sampling tube body 110, thereby driving the sampling assembly 130 to reciprocate between the sampling position and the analysis position. When the sampling assembly 130 moves to the sampling position, the fermented feed at the preset depth position of the fermentation tank 200 is filled into the feed receiving channel 134; when the sampling assembly 130 moves back to the analysis position, the fermented feed in the feed receiving channel 134 is brought back into the sampling tube body 110. Among them, when the sampling component 130 is located at the analysis position, the push rod 131 and the inner side of the tube wall of the sampling tube body 110 are slidably sealed. On the one hand, before the sampling tube body 110 extends to the preset depth position, the fermented feed in the fermentation tank 200 is prevented from entering the feed containing channel 134 in advance; on the other hand, the control core 133 is slidably sealed with the inner side of the tube wall of the sampling tube body 110. After the sampling is completed, the fermented feed in the feed containing channel 134 can be better sealed in the sampling tube body 110, which is conducive to more accurate and controllable sampling and analysis at different preset depth positions.

[0076] It is understandable that in the embodiments of the present application, the biological feed fermentation process analysis system can be flexibly configured with corresponding analysis workbenches, analysis instruments, etc. as needed. Specifically, regarding the analysis after the sampling is completed, as an example, the target sample to be analyzed is taken out from the accommodating cavity inside the sampling tube body 110 through the sampling window, and then the target sample to be analyzed is analyzed, so as to judge the fermentation state according to the analysis result. Among them, the target sample to be analyzed can be a fermented feed mixture, solid matter in the fermented feed, liquid matter in the fermented feed, mixed gas products in the fermented object, etc. The analysis method is, for example, but not limited to, appearance property analysis and chemical composition analysis; for the fermented feed mixture and the solid matter in the fermented feed, for example, the fermentation degree can be preliminarily analyzed by observing the fluffiness, color, degree of decay, etc., and then the fermentation degree and whether the fermentation is abnormal can be judged by combining the chemical composition analysis; for the liquid matter in the fermented feed and the mixed gas products in the fermented object, for example, the chemical composition analysis can be used to judge whether the fermentation is abnormal.

[0077] Continue to see Figure 2~Figure 6 In some embodiments, the biological feed fermentation process analysis system 100 further includes a partition 150, which is connected to the analysis tube section 112, and the partition 150 is sealed with the inner side of the tube wall of the analysis tube section 112. As an example, the side of the partition 150 is fixedly connected to the inner side of the tube wall of the analysis tube section 112 to achieve the connection and sealing between the two; as another example, the end of the partition 150 away from the sampling tube body 110 is fixedly connected to the end of the analysis tube section 112 away from the sampling tube body 110 to achieve the connection between the two, and the side of the partition 150 is sealed with the tube wall of the analysis tube section 112 to achieve the sealing between the two.

[0078] Based on the implementation scheme designed with a partition 150, the control core 133 includes a first core body 1331 and a second core body 1332 respectively located on both sides of the partition 150. As an example, the first core body 1331 and the second core body 1332 are symmetrically arranged relative to the partition 150; the first core body 1331 and the second core body 1332 are both slidably sealed with the inner side of the tube wall of the corresponding sampling tube body 110.

[0079] Correspondingly, the first core 1331 and the second core 1332 are both fixedly connected to the push rod 131 through the connecting piece 132; it should be noted that the first core 1331 and the second core 1332 can be connected to the same connecting piece 132, or to different connecting pieces 132. As an example, the connecting piece 132 is designed to have two groups, and the number of connecting pieces 132 in each group is, for example, one, wherein one group of connecting pieces 132 is connected between the first core 1331 and the push rod 131, and the other group of connecting pieces 132 is connected between the second core 1332 and the push rod 131.

[0080] Correspondingly, the driving mechanism 140 is connected to at least one of the first core 1331 and the second core 1332. As an example, the driving mechanism 140 includes a first driving rod and a second driving rod extending along the axial direction of the sampling tube body 110, and also includes a driving connector 132 connected between the first driving rod and the second driving rod; wherein the first driving rod is connected to the first core 1331, and the second driving rod is connected to the second core 1332. The driving connector 132 serves as a driving end to connect power and synchronously drive the first driving rod and the second driving rod.

[0081] Correspondingly, the tube wall of the analysis tube section 112 is provided with sampling windows respectively located on both sides of the partition 150 .

[0082] See also Figure 3 and Figure 4 When the sampling assembly 130 is located at the analysis position, the partition 150 is against the push rod 131; that is, at this time, the partition 150 separates the feed containing channel 134 and the fermented feed therein into two parts, one of which corresponds to the first core 1331, and the other corresponds to the second core 1332, and sampling and analysis can be carried out separately through the sampling windows located on both sides of the partition 150.

[0083] See also Figure 3 and Figure 4 as well as Figure 7 and Figure 8 Based on the design of the partition 150, the first core 1331 and the second core 1332, the sampling assembly 130 is configured to be able to reciprocate between the analysis position and the squeezing position along the axial direction of the sampling tube body 110, and the analysis position is located between the sampling position and the squeezing position. That is, after the sampling assembly 130 moves from the sampling position extending the sampling pipe to the analysis position retracting the sampling pipe, it can also be retracted deeper into the sampling pipe to reach the squeezing position. When the sampling assembly 130 reciprocates between the analysis position and the squeezing position, the first core 1331 and the second core 1332 are both slidably sealed with the partition 150.

[0084] A support plate 113 is protruded from the analysis tube section 112, and the support plate 113 is located on the side of the control core 133 away from the sliding tube section 111. As an example, the shape of the support plate 113 matches the analysis tube section 112, and its edge is connected to the inner side of the tube wall of the analysis tube section 112; correspondingly, in an embodiment in which the driving mechanism 140 is provided with a driving rod, the driving rod is slidably provided on the support plate 113 along the axial direction of the sampling tube body 110.

[0085] See also Figure 4 and Figure 8The sampling assembly 130 further includes a slide bar 135 and a squeeze plate 136 connected to each other. The slide bar 135 is slidably disposed in the first core 1331 along the axial direction of the sampling tube 110, and the squeeze plate 136 is located on a side of the first core 1331 away from the abutment plate 113. Figure 4 When the sampling assembly 130 is located at the analysis position, the slide bar 135 abuts against the abutment plate 113, and the squeezing plate 136 is slidably sealed with the inner side of the tube wall of the sampling tube body 110 and the partition 150, respectively, so that when the sampling assembly 130 moves from the analysis position to the squeezing position, the squeezing plate 136 and the first core body 1331 gradually move away, and when the sampling assembly 130 moves from the squeezing position to the analysis position, the squeezing plate 136 and the first core body 1331 gradually move closer.

[0086] The above design works as follows:

[0087] When the sampling assembly 130 moves from the analysis position to the extrusion position, the first core body 1331 moves in the direction away from the sliding tube section 111. Since the sliding rod 135 is abutted against the abutting plate 113, the sliding rod 135 no longer moves with the first core body 1331 in the direction away from the sliding tube section 111, so that the extrusion plate 136 connected to the sliding rod 135 gradually moves away from the first core body 1331.

[0088] When the sampling assembly 130 moves from the extrusion position to the analysis position, the first core body 1331 moves toward the direction close to the sliding tube section 111. Since the extrusion plate 136 is slidably sealed with the inner side of the tube wall of the sampling tube body 110 and the partition 150 respectively, for example, by designing the sliding resistance of the extrusion plate 136 to be greater than the sliding resistance of the extrusion plate 136 and the first core body 1331 close to the sliding rod 135, the sliding rod 135 and the first core body 1331 slide relatively while the extrusion plate 136 remains stationary, so that the extrusion plate 136 and the first core body 1331 gradually approach each other until the sampling assembly 130 moves to the analysis position and the extrusion plate 136 and the first core body 1331 are in contact, at which time the original state of the analysis position is restored.

[0089] Based on the above design, since the extrusion plate 136 is slidably sealed with the inner side of the tube wall of the sampling tube body 110 and the partition 150, the fermented feed corresponding to the first core 1331 can be squeezed and compressed during the process of the extrusion plate 136 and the first core 1331 gradually moving away from each other. That is to say, after the sampling assembly 130 moves to the extrusion position, the fermented feed corresponding to the first core 1331 is a compressed material sample, and the fermented feed corresponding to the second core 1332 is an original material sample. The compressed material sample and the original material sample are taken out respectively to complete the material collection. After the material collection is completed, the fluffiness of the fermented feed can be judged by comparing the compressed material sample and the original material sample; compared with conventional component analysis, more dimensional analysis results are obtained, which is conducive to a more comprehensive analysis of the fermentation situation and a more accurate regulation of the fermentation conditions.

[0090] It is understandable that when comparing the compressed material sample and the original material sample, different analysis operations can be performed according to different accuracy requirements of the analysis results. For example, in the initial analysis and judgment, only morphology observation can be performed; further, density testing can be performed, and the travel data from the analysis position to the extrusion position can be combined for analysis. Since the force driving the sampling component 130 during the compression process will gradually increase, the force of the driver from the analysis position to the extrusion position can also be combined for analysis.

[0091] In some embodiments, when the sampling assembly 130 is located at the analysis position, the squeezing plate 136 is magnetically attached to the first core 1331 , and the sliding rod 135 is magnetically attached to the supporting plate 113 .

[0092] Based on the above design, since the slide bar 135 is magnetically attached to the supporting plate 113, when the sampling assembly 130 moves from the extrusion position to the analysis position, the slide bar 135 and the extrusion plate 136 can remain relatively fixed to the sampling tube body 110 relatively stably, which is conducive to the reliability of the gradual approach of the extrusion plate 136 and the first core body 1331, and can ensure that the sampling assembly 130 returns to the original state of the extrusion plate 136 and the first core body 1331 when reaching the analysis position; in addition, since the extrusion plate 136 and the first core body 1331 are magnetically attached, when the sampling assembly 130 moves between the sampling position and the analysis position, the extrusion plate 136 can be stably attached to the first core body 1331. Based on this, on the one hand, a gap between the extrusion plate 136 and the first core body 1331 can be avoided, thereby preventing the fermented feed from being stuck between the extrusion plate 136 and the first core body 1331, so that the fermented feed corresponding to the first core body 1331 after sampling can be effectively squeezed by the extrusion plate 136.

[0093] Continue to see Figure 4 and Figure 8In some embodiments, the sampling assembly 130 further includes a water absorbing layer 137 , which is detachably connected to the squeezing plate 136 , and the squeezing plate 136 is provided with a through hole extending through the axial direction of the sampling tube body 110 .

[0094] There is no limitation on the detachable manner of the extrusion plate 136 and the water absorbing layer 137. As an example, a water absorbing installation groove is provided on one side of the extrusion plate 136 close to the first core body 1331, and the water absorbing layer 137 is detachably embedded in the water absorbing installation groove.

[0095] The wall of the analysis tube section 112 is also provided with a water sampling operation window and a gas sampling port on the side close to the first core body 1331. When the sampling assembly 130 is in the extrusion position, the sampling window is located on the side of the extrusion plate 136 away from the abutment plate 113, the water sampling operation window corresponds to the extrusion plate 136, and the gas sampling port is located on the side of the extrusion plate 136 close to the abutment plate 113.

[0096] It is understandable that the water absorption sampling operation window is a window that can be opened and closed to replace the water absorption layer 137, and it is connected to the accommodating cavity inside the sampling tube body 110; the water absorption sampling operation window can be designed in a conventional manner, such as but not limited to connecting the window door by means of snap connection, thread connection, etc. to achieve opening and closing. The gas sampling port is an opening that can be opened and closed for gas sampling, and it is connected to the accommodating cavity inside the sampling tube body 110; the gas sampling port can be designed in a conventional manner, such as but not limited to connecting the air guide pipe through a control valve to achieve opening and closing.

[0097] Based on the above design, when the sampling component 130 is located at the extrusion position, the solid fermented feed is sampled through the sampling window, so that the solid body of the fermented feed can be analyzed; the water absorption layer 137 is replaced through the water absorption sampling operation window, and the liquid squeezed out of the fermented feed is absorbed by the water absorption layer 137, so that the liquid components squeezed out of the fermented feed can be analyzed; the gas squeezed out of the fermented feed can be sampled through the gas sampling port, so that the gas components squeezed out of the fermented feed can be analyzed. Based on this, sampling the solid fermented feed, the squeezed liquid, and the squeezed gas separately can be analyzed more comprehensively, which is conducive to more comprehensive analysis of the fermentation situation and more accurate regulation of the fermentation conditions.

[0098] In some embodiments, the end of the analysis tube segment 112 away from the sliding tube segment 111 has an end plate 114. As an example, the shape of the end plate 114 matches the analysis tube segment 112, and its edge is connected to the inner side of the tube wall of the analysis tube segment 112; correspondingly, in an embodiment in which the driving mechanism 140 is provided with a driving rod, the driving rod is slidably disposed in the end plate 114 along the axial direction of the sampling tube body 110.

[0099] An elastic restoring member 115 is provided between the end plate 114 and the abutting plate 113. The elastic restoring member 115 is, for example, a telescopic spring. The end of the partition 150 is slidably disposed in the abutting plate 113 and connected to the elastic restoring member 115. When the sampling assembly 130 is located at the analysis position, the elastic restoring member 115 is in a natural state; when the sampling assembly 130 is located at the extrusion position, the elastic restoring member 115 is in an elastically deformed state.

[0100] Based on the above design, when the sampling component 130 is in the squeeze position, the telescopic spring can provide the sampling component 130 with elastic restoring force to move to the analysis position, thereby more conveniently and accurately driving the sampling component 130 to return from the squeeze position to the analysis position.

[0101] Furthermore, in some embodiments, the inner wall of the analysis tube section 112 is provided with a sliding groove extending axially along the sampling tube body 110, and the edge of the partition 150 is slidably sealed with the sliding groove; when the sampling assembly 130 is located in the analysis position, the partition 150 is supported against the side wall of the sliding groove close to the sliding tube section 111.

[0102] In the above design, the sliding groove can guide the axial movement of the partition 150, and is also conducive to better realizing the sliding sealing cooperation between the edge of the partition 150 and the inner wall of the analysis tube section 112; in addition, when the sampling component 130 is located in the analysis position, the partition 150 is abutted against the groove side wall of the sliding groove, and the movement position of the partition 150 can also be positioned, so that the position of the partition 150 when the sampling component 130 is in the analysis position is more accurately controllable.

[0103] See also Fig. 9 Optionally, the partition 150 is arranged longitudinally, and the first core 1331 and the second core 1332 are distributed transversely.

[0104] Based on this, the influence of gravity on the distribution of fermented feed in the feed containing channel 134 corresponding to the first core 1331 and the second core 1332 can be avoided, so that when the sampling component 130 moves to the analysis position, the distribution of the fermented feed in the first core 1331 and the second core 1332 has better consistency, which is conducive to more accurate and reliable comparison of the fermented feed in the first core 1331 and the second core 1332.

[0105] Further, in some embodiments, the connector 132 connected to the first core 1331 is located on a side of the first core 1331 away from the second core 1332, the connector 132 connected to the second core 1332 is located on a side of the second core 1332 away from the first core 1331, and the feed containing channel 134 is located between the connectors 132 on both sides.

[0106] In the above design, the first core 1331 and the second core 1332 are respectively connected by two connecting members 132, so that the connection between the control core 133 and the push rod 131 is more stable. The two connecting members 132 are respectively located on the side away from the first core 1331 and the second core 1332, so as to prevent the connecting members 132 from affecting the fermented feed from falling into the feed containing channel 134.

[0107] See also Fig.10 Furthermore, the connecting member 132 is designed to have a certain height, for example, the connecting member 132 is designed to be an arc-shaped connecting plate corresponding to the sampling tube body 110. Since the two connecting members 132 are respectively located on the side away from each other of the first core body 1331 and the second core body 1332, the connecting plate can close the feed receiving channel 134 on both sides. When the sampling assembly 130 moves from the sampling position to the analysis position, the fermented feed filled into the feed receiving channel 134 can be more enclosed in the feed receiving channel 134, so that more fermented feed can be filled into the feed receiving channel 134 after the sampling is completed. Based on this, on the one hand, more sampling volume can better meet more analysis, and on the other hand, when the fermented feed corresponding to the first core body 1331 is squeezed by the squeezing plate 136, the squeezing movement stroke required to achieve the same squeezing degree is shorter, which can reduce the overall movement stroke of the sampling assembly 130, thereby reducing the axial size of the sampling tube body 110.

[0108] In a second aspect, an embodiment of the present application provides a method for optimizing bio-feed fermentation, comprising: using the bio-feed fermentation process analysis system 100 provided in the above embodiment to perform fermentation analysis on the fermentation process, and then regulating the fermentation conditions according to the analysis results.

[0109] The biological feed fermentation process analysis system 100 is connected to the sampling port of the fermentation tank 200 through the sliding sleeve 120, and the fermentation analysis includes:

[0110] The position of the control core 133 is adjusted to place the sampling assembly 130 at the analysis position; then the sliding tube section 111 is driven to slide relative to the sliding sleeve 120, so that the end of the sliding tube section 111 extends into the preset depth position in the fermentation tank 200; the position of the control core 133 is adjusted again to move the sampling assembly 130 to the sampling position, so that the fermented feed at the preset depth position is filled into the feed containing channel 134; the position of the control core 133 is adjusted again to return the sampling assembly 130 to the analysis position, so that the fermented feed in the feed containing channel 134 is pushed into the position corresponding to the sampling window in the sampling tube body 110; samples are taken from the sampling window for analysis.

[0111] In the above embodiment, the position of the control core 133 is regulated by controlling the driving mechanism 140, and the sampling window is opened to take out the solid fermented feed during sampling, and the sampling window is closed after the sampling is completed.

[0112] Furthermore, in the embodiment with the partition 150, after the sampling assembly 130 returns to the analysis position and before sampling at the sampling window for analysis, it further includes: adjusting the position of the control core 133 so that the sampling assembly 130 is located at the compression position. The operation of sampling at the sampling window includes: opening the sampling window corresponding to the first core 1331 to sample the compressed material sample; opening the sampling window corresponding to the second core 1332 to sample the original material sample.

[0113] Furthermore, in an implementation scheme configured with a water absorption layer 137, a water absorption sampling operation window and a gas sampling port, after the sampling assembly 130 is located in the extrusion position, it also includes: opening the water absorption sampling operation window to replace the water absorption layer 137 to sample the squeezed liquid, and opening the gas sampling port to sample the squeezed gas.

For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
