Description

Technical Field

[0001] This utility model relates to the field of microbial fermentation technology, specifically a sampling and detection device based on microbial fermentation. Background Technology

[0002] During fermentation, microbial strains can decompose complex organic matter and transform it into a more easily digestible and absorbable form. For example, lactic acid bacteria fermentation can convert lactose into lactic acid, increasing the sourness and taste of yogurt, while also improving the bioavailability of minerals such as calcium and phosphorus. However, existing microbial strains require sampling and testing after fermentation. Current sampling devices can only sample one group at a time. If sampling is required at different depths of the fermentation broth, multiple operations are necessary, affecting sampling efficiency. Furthermore, the inlet height of existing sampling devices is uniform, preventing simultaneous sampling of fermentation broth at different depths and affecting the accuracy of subsequent fermentation data testing.

[0007] Preferably, the position adjustment structure includes a first sliding plate, on which a height adjustment component is slidably connected.

[0008] Preferably, the height adjustment component includes a gear, the rotation of the gear drives the rack to move up and down, and the up and down movement of the connecting plate drives the slider on the connecting plate to slide up and down in the groove of the first sliding plate.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a sampling and detection device based on microbial fermentation, such as... Figure 1 , Figure 2 and Figure 3 As shown, the device includes a sampling structure 1, which includes a sampling tube housing 11. A sealing cap 12 is fixed to the upper side of the sampling tube housing 11. An automatic storage component 13 is embedded in both the sampling tube housing 11 and the sealing cap 12. The automatic storage component 13 is connected to a conveying component 14. The automatic storage component 13 includes a storage tube 131. A piston 132 is embedded in the storage tube 131. A connecting rod 133 is fixed to the piston 132. An electric telescopic rod 134 is fixed to the connecting rod 133. The conveying component 14 includes a first feed pipe 141. The first feed pipe 141 is disassembled and installed with a conveying pipe 142 through a threaded hollow connector. The conveying pipe 142 is disassembled and installed with a second feed pipe 143 through a threaded hollow connector. The second feed pipe 143 is connected to a suction head 144.

[0026] Among them, there are five sets of automatic storage components 13. The five sets of automatic storage components 13 are symmetrically arranged about the central axis of the sampling tube shell 11. The upper side of the sealing cover 12 is connected to an annular cover with a threaded seal. The annular cover seals the automatic storage components 13 to prevent impurities from falling into the automatic storage components 13 when the sampling structure 1 is not in use. The sealing cover 12 is fixed with a control device for controlling the overall equipment.

[0027] Specifically, the suction head 144 and the connecting plate 223 are disassembled and installed;

[0028] In the above scheme, with the assistance of the electric telescopic rod 134 on the upper side of the sealing cap 12 on the outer shell 11 of the sampling tube, the connecting rod 133 is driven to move upward. The upward movement of the connecting rod 133 drives the piston 132 to move upward in the storage tube 131, so that the fermentation liquid is finally stored in the storage tube 131 through the suction head 144, the second feed pipe 143, the conveying pipe 142 and the first feed pipe 141.

[0029] like Figure 1 As shown, the sampling structure 1 is fixed with a position adjustment structure 2 and a width adjustment structure 3. The position adjustment structure 2 includes a first sliding plate 21. A height adjustment component 22 is slidably connected to the first sliding plate 21. The height adjustment component 22 includes a gear 221. The rotation of the gear 221 drives the rack 222 to move up and down. The up and down movement of the connecting plate 223 drives the slide bar 224 on the connecting plate 223 to slide up and down in the groove on the first sliding plate 21.

[0030] Among them, the position adjustment structure 2 is provided with five sets, and the five sets of position adjustment structures 2 are symmetrically arranged about the central axis of the sampling tube shell 11;

[0031] Specifically, a storage battery is fixed on the upper side of the first sliding plate 21, which provides power to the entire device, and a small motor is fixed inside the first sliding plate 21.

[0032] In the above scheme, the gear 221 is driven to rotate by the motor inside the first sliding plate 21. The rotation of the gear 221 drives the connecting plate 223 on the rack 222 to adjust its position. The movement of the connecting plate 223 drives the slide bar 224 on the connecting plate 223 to slide in the groove opened on the first sliding plate 21, thereby adjusting the height of the five sets of suction heads 144 on the lower side as needed. Later, the fermentation liquid at different depths inside the fermenter is sampled, thereby reducing the number of samplings and increasing the accuracy of the sampling and testing data.

[0033] like Figure 1 , Figure 2 and Figure 4As shown, the width adjustment structure 3 is located above the position adjustment structure 2. The width adjustment structure 3 includes a width adjustment component 31, through which an auxiliary support component 32 passes. The width adjustment component 31 includes a first support plate 311, a second sliding plate 312 is slidably connected inside the first support plate 311, and a second support plate 313 is fixed on the second sliding plate 312. The auxiliary support component 32 includes a screw 321, a rotating handle 322 is fixed on the upper side of the screw 321, and the position of the anti-slip plate 324 is adjusted by a universal joint 323 on the lower side of the screw 321.

[0034] Specifically, the width adjustment structure 3 is provided in two sets, and the two sets of width adjustment structures 3 are symmetrically arranged about the central axis of the sealing cover 12;

[0035] Furthermore, the first support plate 311 has multiple sets of limiting holes, which are evenly distributed on the first support plate 311. The second sliding plate 312 is inlaid with two sets of limiting protrusions, thereby adjusting the length of the second sliding plate 312 and limiting and fixing it.

[0036] Specifically, two sets of nuts pass through the screw 321, and the arrangement of the two sets of screws 321 limits the movement of the screw 321;

[0037] In the above scheme, pressing the limiting protrusion, the limiting protrusion is located inside the first support plate 311. After pulling the second sliding plate 312 to the desired position, the limiting protrusion is limited to the inside of the limiting hole under its own elastic force, thereby extending the length of the first support plate 311 and preventing the sampling structure 1 from falling off due to the sampling hole being too large. The user drives the screw 321 on the second support plate 313 to move by rotating the rotating handle 322, thereby driving the anti-slip plate 324 to the desired position. With the assistance of the universal joint 323, the anti-slip plate 324 fits into the fermentation tank, thereby playing an auxiliary support role.

[0038] Working principle: When using this sampling and detection device based on microbial fermentation, connect the external power supply, sample the fermentation liquid through the sampling structure 1, adjust the height of the suction head 144 through the position adjustment structure 2, and adjust the width of the sealing cover 12 through the width adjustment component 31.
