Description

TECHNICAL FIELD

[0001] The application relates to the field of sampling technology, in particular to a sampling device for detecting low-salt high-fresh seasoning sauce. BACKGROUND

[0002] In the field of food industry, seasoning sauce as a key auxiliary material for improving the flavor of food, its quality safety and nutritional ingredient stability are directly related to the quality of the terminal product and the health of consumers. Among them, low-salt high-fresh seasoning sauce has been growing in market demand in recent years due to its healthy and rich flavor characteristics, and the accurate detection of its core parameters such as salt content, umami substance (such as disodium inosinate, sodium glutamate, etc.) concentration, microbial indicators and impurity content has become a key link in the production process quality control and factory inspection. As the first step in the detection process, the representativeness, purity and sampling efficiency of the sample directly determine the accuracy of the subsequent detection data, so a high-performance sampling device is a key equipment for ensuring the quality detection of seasoning sauce.

[0003] Currently, low-salt high-fresh seasoning sauce sampling mainly adopts traditional manual sampling or simple mechanical sampling method, which has exposed many technical defects in actual application and is difficult to meet the requirements of modern detection for accuracy, efficiency and safety:

[0004] Firstly, the sample representativeness is insufficient, and the detection data is biased. Low-salt high-fresh seasoning sauce is mostly viscous colloid, and traditional sampling devices mostly use fixed-point sampling, such as tank mouth surface or single-depth sampling, which cannot achieve uniform sampling at different depths and different radial positions in the tank. Because seasoning sauce is prone to component stratification due to gravity during storage, such as oil floating and solid particles settling, a single-point sample cannot reflect the true composition of the overall product, resulting in significant deviation of the subsequent salt and umami substance detection results from the actual values, which may cause misjudgment of qualified products or missed detection of unqualified products.

[0005] Secondly, the sampling composition cannot be selected. Because a certain amount of liquid or gel is required for detection, and there are a large number of solid seasonings such as soybeans and peanuts in seasoning sauce, the current sampling device cannot remove the fixed seasonings for sampling, resulting in that the sampling amount cannot meet the detection requirements, and multiple sampling is required, which is cumbersome and reduces the detection efficiency.

[0006] Thirdly, the sampling amount is not adjustable. Low-salt high-fresh seasoning sauce has high viscosity, and different amounts of sampling are required for different component detection, and the existing device lacks a sampling amount adjusting structure, which cannot accurately control the sample volume according to the requirements of different detection items, such as a small amount of sample for microbial detection and a large amount of sample for component analysis, resulting in sample waste or poor detection data repeatability.

[0035] Example two

[0036] On the basis of example one, as shown in Figure 1 and Figure 2 The negative pressure device includes a sampling bottle 19, a threaded cap 53 and a negative pressure pump, the bottle opening of the sampling bottle 19 is provided with an external thread, the threaded cap 53 is threadedly installed on the bottle opening of the sampling bottle 19, the negative pressure hose 9 is connected to the threaded cap 53, the negative pressure pump is connected to the threaded cap 53 through the hose 54, the negative pressure hose 9 is provided with a solenoid valve, before sampling, the solenoid valve is in passage, the sampling bottle 19 is installed on the threaded cap 53, the sampling bottle 19 is vacuumized with the sampling cavity 4 through the negative pressure pump, then the solenoid valve is closed and the negative pressure pump stops working, under the action of negative pressure, the sample enters into the sampling cavity 4, realizing quantitative sampling, then the switching disc 7 blocks the filter hole 6 and the solenoid valve is opened, under the vacuum action of the sampling bottle 19, the sample in the sampling cavity 4 enters into the sampling bottle 19, realizing remote sampling, at the same time, the sampling cavity 4 can be in empty state again, then the sampling bottle 19 is replaced, and the above method is repeated to sample samples of different depths.

[0037] Example three

[0038] On the basis of example two, as shown in Figures 1 to 5As shown, the sampling cavity 4 is provided with a sampling adjusting disc 36, which has the freedom of moving along the axial direction of the sampling cavity 4. The sampling adjusting disc 36 is provided with a lip-shaped sealing ring 37, the outer ring of the lip-shaped sealing ring 37 forms a sealing surface with the inner wall of the sampling cavity 4. The size of the sampling cavity between the switching disc 7 and the sampling adjusting disc 36 is adjusted by moving the sampling adjusting disc 36.

Specifically, the adjusting screw 38 is manually rotated to make the adjusting screw 38 perform a screwing-in motion. The bearing 40 is provided to make the sampling adjusting disc 36 and the adjusting screw 38 have the freedom of rotation, so that the adjusting screw 38 drives the sampling adjusting disc 36 to move up and down to adjust the size of the sampling cavity 4. The lip-shaped sealing ring 37 can ensure that the sampling adjusting disc 36 moves while achieving good sealing, so that the sampling amount is more accurate.

[0039] Example Four

[0040] Because different depths of sampling are required, the length of the sampling column 3 is generally longer than the axial length of the seasoning tank. Therefore, it is very difficult to manually operate the sampling column 3 to move. The extension range of the power source such as the air cylinder is difficult to meet the moving length of the sampling column 3. Therefore, on the basis of example three, as shown in FIG. 6, the sampling column 3 is provided with a sampling adjusting disc 36, which is provided with a lip-shaped sealing ring 37. The outer ring of the lip-shaped sealing ring 37 forms a sealing surface with the inner wall of the sampling cavity 4. The size of the sampling cavity between the switching disc 7 and the sampling adjusting disc 36 is adjusted by moving the sampling adjusting disc 36. The top of the sampling column 3 is threadedly connected with an adjusting screw 38. The top of the sampling adjusting disc 36 is provided with a bearing groove 39, which is provided with a bearing 40. The outer ring of the bearing 40 is fixed to the sampling adjusting disc 36. One end of the adjusting screw 38 is keyed to the inner ring of the bearing 40. The negative pressure hose 9 passes through the sampling adjusting disc 36 to communicate with the sampling cavity 4, so that the negative pressure hose 9 can move with the sampling adjusting disc 36. Before the detachable sampling mechanism is installed, the size of the sampling cavity 4 is adjusted according to the required sampling amount. Specifically, the adjusting screw 38 is manually rotated to make the adjusting screw 38 perform a screwing-in motion. The bearing 40 is provided to make the sampling adjusting disc 36 and the adjusting screw 38 have the freedom of rotation, so that the adjusting screw 38 drives the sampling adjusting disc 36 to move up and down to adjust the size of the sampling cavity 4. The lip-shaped sealing ring 37 can ensure that the sampling adjusting disc 36 moves while achieving good sealing, so that the sampling amount is more accurate. Figures 1 to 3As shown, the rotating disc 2 is provided with a telescopic mechanism, the telescopic mechanism includes a fixed bottom plate 41, a first lifting plate 42, a second lifting plate 43 and a third lifting plate 44, the fixed bottom plate 41 is vertically fixed on the rotating disc 2, the first lifting plate 42 is slidingly installed on the fixed bottom plate 41, the second lifting plate 43 is slidingly installed on the first lifting plate 42, and the third lifting plate 44 is slidingly installed on the second lifting plate 43, the top of the third lifting plate 44 is connected with the sampling column 3, the first lifting plate 42 and the second lifting plate 43 are both provided with a belt drive assembly, the belt drive assembly includes a first pulley 45 and a second pulley 46 which are rotatably installed, the first pulley 45 and the second pulley 46 are spaced apart along the telescopic direction of the telescopic mechanism, the first pulley 45 and the second pulley 46 are drivingly connected through a driving belt 47, one side of the driving belt 47 on the first lifting plate 42 is connected with the fixed bottom plate 41 through a first connecting block 48, the other side of the driving belt 47 on the first lifting plate 42 is connected with the second lifting plate 43 through a second connecting block 51, one side of the driving belt 47 on the second lifting plate 43 is connected with the first lifting plate 42 through a third connecting block 52, the other side of the driving belt 47 on the second lifting plate 43 is connected with the third lifting plate 44 through a fourth connecting block 49, a lifting electric push rod 50 is installed on the fixed bottom plate 41, the telescopic shaft of the lifting electric push rod 50 is connected with the first lifting plate 42, the top of the third lifting plate 44 is connected with a detachable plate through screws, the detachable plate is connected with the sampling column 3 through screws, both ends of the bottom of the fixed bottom plate 41 are fixed with wing plates, the wing plates are connected with the rotating disc 2 through screws, so that the telescopic mechanism and the sampling column 3 are both installed on the rotating disc 2 in a detachable manner, when installing, the mounting disc 1 is first installed on the sampling pipe opening, then the telescopic mechanism is installed on the rotating disc 2, and finally the sampling column 3 is passed through the rotating disc 2 and connected with the third lifting plate 44, the assembly of the detachable sampling mechanism is installed, and the specific movement process of the sampling column 3 is as follows: the lifting electric push rod 50 drives the first lifting plate 42 to move upwards, the first lifting plate 42 drives the belt drive assembly thereon to move, since the driving belt 47 is connected with the fixed bottom plate 41 through the first connecting block 48, the fixed bottom plate 41 does not move with the first lifting plate 42, so that the first connecting block 48 drives the driving belt 47 to move, since the movement directions of the two sides of the driving belt 47 are opposite, when the first lifting plate 42 moves upwards, the first connecting block 48 drives the driving belt 47 on one side to move downwards, so that the driving belt 47 on the other side drives the second lifting plate 43 to move upwards through the second connecting block 51, so that the second lifting plate 43 extends from the first lifting plate 42, similarly, when the second lifting plate 43 extends from the first lifting plate 42, the belt drive assembly thereon will move, so that one side of the driving belt 47 moves downwards under the action of the third connecting block 52, and then the other side of the driving belt 47 drives the third lifting plate 44 to move upwards through the fourth connecting block 49, so that the telescopic mechanism is extended by three stages, and the telescopic stroke of the lifting electric push rod 50 is expanded,To meet the sampling needs of the seasoning container, initially, the double-stroke telescopic mechanism is in the extended state, ensuring that the sampling column 3 has not yet entered the seasoning container. After the detachable sampling mechanism is installed, the double-stroke telescopic mechanism moves the sampling column 3 downwards, allowing the sampling column 3 to sequentially complete sampling operations at various depths.

[0041] Example 5

[0042] Based on Example 4, such as Figures 1 to 7 As shown, the diameter of the switching disk 7 is smaller than the diameter of the sampling chamber 4. Two drive blocks 10 are fixed at intervals along the circumference of the side wall of the switching disk 7. A traction drive mechanism is provided on the outer wall of the sampling column 3. The traction drive mechanism includes a drive seat 11, on which a first winding shaft 12 and a second winding shaft 13 are rotatably mounted. The rotation direction of the first winding shaft 12 is opposite to that of the second winding shaft 13. A first pull wire 14 and a second pull wire 15 are wound on the first winding shaft 12 and the second winding shaft 13, respectively. The first pull wire 14 and the second pull wire 15 are separated. Two drive blocks 10 are connected. A first gear 16 and a second gear 17 are respectively connected to the first winding shaft 12 and the second winding shaft 13. The first gear 16 meshes with the second gear 17. A drive disk 18 is fixed to the end of the first winding shaft 12 away from the first gear 16. A lever 20 is fixed to the side wall of the drive disk 18. The lever 20 is hinged to the telescopic rod of the electric push rod 21. The cylinder of the electric push rod 21 is hinged to the drive seat 11. The extension and retraction of the electric push rod 21 drives the lever 20 to deflect. The lever 20 drives the first winding shaft 12 to deflect through the drive disk 18. The first winding shaft 12 drives the second winding shaft 13 to deflect through the meshing of the first gear 16 and the second gear 17. The deflection direction of the first winding shaft 12 is opposite to that of the second winding shaft 13, so that when the first winding shaft 12 winds up the first pull wire 14, the second winding shaft 13 releases the second pull wire 15. Initially, the switching disk 7 blocks the filter hole 6. When sampling is required, the electric push rod 21 extends and drives the first winding shaft 12 to wind up the first pull wire 14, causing the first pull wire 14 to pull the switching disk 7 to deflect. At the same time, the second winding shaft 13 releases the second pull wire 15 appropriately. The deflection of the switching disk 7 causes the sampling hole 8 of the switching disk 7 to connect with the filter hole 6, thus completing the sampling of the seasoning sauce sample. After the sampling is completed, the electric push rod 21 retracts and resets, causing the second winding shaft 13 to wind the second pull wire 15. At the same time, the first winding shaft 12 rotates in the opposite direction to release the first pull wire 14, so that the switching disk 7 can be smoothly rotated and reset to re-seal the filter hole 6. Through the drive method of the pull wire, the switching disk 7 can be driven to rotate in a narrow space without occupying the internal space of the sampling chamber 4, and the direct installation of the drive device is avoided to prevent sample contamination.

[0043] Furthermore, both the first pull wire 14 and the second pull wire 15 are equipped with a guide ring 22, which is fixed on the filter plate 5. Two pull wire paths 23 are provided between the inner and outer walls of the sampling column 3. One end of the pull wire path 23 is connected to the sampling chamber 4, and the other end passes through the outer wall of the sampling column 3. The first pull wire 14 passes through one of the guide rings 22 and the pull wire path 23 in sequence and is wound around the first winding shaft 12. The second pull wire 15 passes through the other guide ring 22 and the pull wire path 23 in sequence and is wound around the second winding shaft 13. The guide ring 22 guides the arrangement direction of the first pull wire 14 and the second pull wire 15 so that the first pull wire 14 or the second pull wire 15 can smoothly pull the switching plate 7 to deflect. In specific implementation, two wiring paths are provided on the sampling column 3. The first pull wire 14 and the second pull wire 15 are wired through the two wiring paths respectively. An O-ring is provided at the end of the wiring path near the sampling chamber 4 to seal and prevent the sample from entering the wiring path.

[0044] Example 6

[0045] Based on Example 5, such as Figures 1 to 5 As shown, a pressure detection mechanism is provided on the sampling column 3. The pressure detection mechanism includes a pressure cone 24, a pressure sensor 25, and a pressure push rod 26. The large-diameter end of the pressure cone 24 is located at the bottom of the sampling column 3. Several strip grooves 27 are formed on the large-diameter end face of the pressure cone 24. The strip grooves 27 are arranged radially through the pressure cone 24, allowing the sample to enter the filter pore 6 through the strip grooves 27. The pressure sensor 25 is arranged at the top of the sampling column 3. A detection cavity 28 is provided between the inner and outer walls of the sampling column 3. The pressure push rod 26 is movably arranged in the detection cavity 28. The two ends of the pressure push rod 26 act on the pressure axis of the pressure cone 24 and the pressure sensor 25, respectively. The sampling column 3 moves downward. When sampling is performed, if the pressure cone 24 is blocked by the blade, the sampling column 3 cannot continue to move downward. At this time, the pressure cone 24 transmits the squeezing force to the pressure sensor 25 through the pressure push rod 26. When the pressure of the pressure sensor 25 reaches the set value, it indicates that the sampling column 3 is blocked by the blade. The double stroke telescopic mechanism drives the sampling column 3 to move upward and disengage from the blade. Then, the rotating disk 2 drives the sampling column 3 to deflect, changing the position of the sampling column 3 to continue sampling.

[0047] Example Seven

[0048] On the basis of example six, as Figures 1 to 9As shown, the rotating disk 2 is rotatably mounted on the mounting disk 1 via ball bearings. Two sets of locking and positioning mechanisms are provided between the mounting disk 1 and the rotating disk 2. Each locking and positioning mechanism includes a locking ratchet 55, a locking shaft 56, a locking pawl 57, and a pawl spring 58. The locking ratchet 55 is fitted onto the rotating disk 2, the locking shaft 56 is vertically mounted on the mounting disk 1, the locking pawl 57 is movably fitted onto the locking shaft 56, and a pawl spring 59 is fitted onto the locking shaft 56. The two ends of the pawl spring 59 are respectively connected to the locking pawl 57 and the mounting disk 1, and the pawl spring 58 is fixed. On mounting plate 1, the pawl spring 58 contacts the outer arc surface of the locking pawl 57. A pressing nut 60 is threaded onto the locking shaft 56. The pressing nut 60 presses down on the locking pawl 57, compressing the pawl spring 59. Under the action of the pawl spring 58, the locking pawl 57 is fitted into the ratchet groove of the locking ratchet wheel 55. Two sets of locking positioning mechanisms are installed in opposite directions; one set restricts the forward rotational freedom of the rotating plate 2, and the other set restricts the reverse rotational freedom of the rotating plate 2. A manual lever is fixed to the side wall of the rotating plate 2. After the detachable sampling mechanism is installed, a trial run is performed, which involves moving the sampling column 3 downwards to determine if the blades obstruct it. When the sampling column 3 is obstructed, any locking and positioning mechanism is adjusted to unlock the rotational freedom of the rotating disk 2 in one direction. The specific adjustment process is as follows: unscrew the pressing nut 60 upwards, causing the locking pawl 57 to move upwards under the reaction force of the pawl spring 59, separating the locking pawl 57 from the locking ratchet 55. This allows the rotating disk 2 to rotate around the direction defined by the locking and positioning mechanism, thereby deflecting the rotating disk 2 and changing the sampling column 3. Positioning the sampling column 3 to avoid the blades, when the sampling column 3 can move smoothly downwards, it indicates that the position of the sampling column 3 meets the sampling requirements. Rotate the pressing nut 60 downwards, so that the pressing nut 60 drives the locking pawl 57 to move back into the ratchet groove of the locking ratchet 55. Through the combined action of the two sets of locking and positioning mechanisms, the rotational freedom of the rotating disk 2 is restricted, ensuring the positional stability of the sampling column 3 and avoiding the problem of squeezing and deflection during the sampling process. This ensures that samples at different depths at the same position are on the same axis, thereby accurately detecting whether the seasoning sauce is stirred evenly.
