Description

Technical Field

[0001] This invention relates to the field of sauce production technology, specifically to a sauce production testing and sampling device. Background Technology

[0002] Sauces are common condiments used in daily cooking to add flavor and character. They are mainly available in liquid, semi-solid, or solid forms. Currently, in order to ensure the food safety and quality control of sauces meet the set requirements, it is necessary to sample and test the sauces after production.

[0003] Liquid sauces or some semi-solid sauces (such as soy sauce, tomato sauce, and other sauces without solid particles) are usually thoroughly mixed during the production process and can maintain a relatively stable state during storage. However, in order to study certain characteristics of the sauce (such as stratification, sediment analysis, etc.), it is necessary to directly sample from a specific layer of the sauce. Therefore, it is necessary to sample the sauce when it is in a static state. However, changes in the sauce layer during the sampling process can easily lead to the sampled sauce not being from the desired specific layer (the specific area of ​​the sauce).

[0004] Solid sauces are relatively easy to sample due to their solid nature. However, for semi-solid sauces, such as chili sauce and seafood sauce, it is necessary to stir the sauce before sampling and testing in order to detect the actual composition and quality of the corresponding batch of sauce, the testing process for freshly prepared sauces, and the testing process for sauces that may exhibit stratification. Sampling directly without stirring can easily lead to insufficient representativeness of the sampled sauce.

[0005] Current sampling equipment typically uses a single sampling tube inserted into the sauce to extract the sauce. For static sampling, the action of inserting the tube into the sauce can cause the internal components of the sauce to move, affecting the representativeness of the sample. For stirring sampling, manual stirring is required before sampling. Therefore, it is difficult to uniformly meet the requirements of both static and stirring sampling processes.

[0006] Secondly, during the static sampling process, it is necessary to take samples from multiple locations and at different heights. During the stirring sampling process, the degree of uniformity of stirring will also affect the representativeness of the sampled sauce, thus requiring sampling from multiple locations and at different heights as well. The current single sampling tube is difficult to meet the above requirements. Summary of the Invention

[0007] Therefore, it is necessary to provide a sampling device for testing sauce production, which aims to solve the problems of the prior art.

[0008] This application provides a sampling device for testing sauce production, comprising:

[0009] A support frame is placed horizontally above the sauce container, and the support frame is equipped with a sampling mechanism for taking samples at different heights near the wall and at the center of the sauce container.

[0010] The sampling mechanism includes sliding blocks, and two sliding blocks are slidably arranged on the support frame. A rotating shaft is rotatably inserted through both the sliding blocks and the support frame. A sampling cylinder with an open bottom is fixedly arranged below the rotating shaft. The sampling cylinder has multiple material holes that penetrate the sampling cylinder from left to right.

[0011] The support frame is equipped with a drive group for adjusting the sliding blocks, and the two sliding blocks are equipped with a fitting group for fitting against the barrel wall. The drive group and the fitting group work together to bring the left and right sampling cylinders close to the wall.

[0012] The sampling cylinder is rotatably fitted with a rotating component. The rotating component blocks the material hole when the sample is being taken at rest, and keeps the material hole open when the sample is being taken by stirring.

[0013] The sampling cylinder is equipped with a sampling component, which includes a sampling tube and a sealing plate. After the sampling component is installed on the sampling cylinder, the sealing plate is inserted into the sampling cylinder to seal the sauce in the sampling cylinder at a set height.

[0014] A stirring blade is fixedly installed on the sampling tube.

[0015] According to an advantageous embodiment, the drive assembly includes bidirectional threaded rods, and two bidirectional threaded rods that are symmetrical about front and back and extend horizontally along the axis rotate through the support frame. The threaded sections of the bidirectional threaded rods pass through the corresponding sliding blocks and are threadedly engaged with the sliding blocks.

[0016] According to an advantageous embodiment, the bonding assembly includes snap-fit ​​holes, and two sets of symmetrical holes are provided through the sliding block. Each set of holes includes three snap-fit ​​holes that are equidistant from left to right. An L-shaped snap-fit ​​plate is provided on the upper side of the sliding block.

[0017] The lower end face of the snap-fit ​​plate is fixedly provided with an arc-shaped bonding plate, and the horizontal section of the snap-fit ​​plate is fixedly provided with four rectangular snap-fit ​​posts. The bonding plate is installed by snapping the left and right snap-fit ​​posts into the corresponding snap-fit ​​holes. The length of the bonding plate is greater than the length of the sampling tube.

[0018] The distance between the bonding plate and the corresponding sampling cylinder can be adjusted by inserting the snap-fit ​​pin into different snap-fit ​​holes, thereby adapting to both static sampling and stirring sampling needs.

[0019] According to an advantageous embodiment, a connecting ring is fixedly provided on the sliding block and rotatably sleeved on the corresponding rotating shaft. The lower end of the rotating shaft is connected to the inner cavity of the sampling cylinder. A connecting cavity is opened in the connecting ring. A connecting groove is opened on the rotating shaft and connected to the connecting cavity. A connecting pipe is provided on the sliding block and connected to the connecting cavity.

[0020] According to an advantageous embodiment, the rotating component consists of a plurality of rotating cylinders distributed from top to bottom and a guide cylinder at the bottom, wherein the rotating cylinders are connected to each other and to the guide cylinders by L-shaped connecting blocks, and the guide cylinders are, from top to bottom, a cylindrical section and a frustum section.

[0021] The rotating component has through holes that correspond one-to-one with the material holes.

[0022] According to an advantageous embodiment, the rotating member is provided with a locking assembly, which includes a toggle plate, and the toggle plate is fixedly disposed on the upper end face of the rotating member and rotatably sleeved on the rotating shaft.

[0023] The actuation plate is provided with two locking pins that slide up and down. A reset spring located above the actuation plate is fixedly provided between the locking pins and the actuation plate. The upper end face of the sampling cylinder is provided with a locking groove corresponding to the locking pin.

[0024] According to an advantageous embodiment, two sampling tubes on the same sampling cylinder are opposite each other and symmetrical, and the end of the sampling tube near the sampling cylinder is a plug section, the outer diameter of which is the same as the diameter of the material hole.

[0025] The sampling tube has a through-hole on both sides, and the sealing plate is L-shaped and fixedly sleeved on the sampling tube. Two adjacent sealing plates on the same sampling tube are symmetrical. The horizontal section of the sealing plate is inserted into the through-hole to cooperate with the insertion section of the sampling tube to be inserted into the material hole to complete the insertion and installation of the sampling tube. The rotating cylinder on the same sampling tube is staggered from the through-hole.

[0026] After the two adjacent sealing plates on the same sampling tube are inserted into the corresponding insertion slots, the horizontal sections of the two sealing plates fit together to separate the sauce inside the sampling tube.

[0027] According to an advantageous embodiment, the sampling assembly further includes mounting rods, and two mounting rods symmetrically arranged front to back and with their axes extending from left to right are fixedly provided on the left end face of the horizontal section of the sealing plate on the right side of the same sampling cylinder, and a mounting groove corresponding to the mounting rods is provided on the other sealing plate.

[0028] The mounting rod has a locking groove, and a locking pin is installed in the locking groove of two adjacent mounting rods.

[0029] In summary, the present invention has at least one of the following beneficial effects: the three sampling tubes provided in the present invention can perform sampling operations at different heights at the center position and near the wall area of ​​the sauce container through the bonding group, which can adapt to the sampling needs of different positions during static sampling and stirring sampling.

[0030] Secondly, when sampling is performed without a sampling tube, and the sauce enters the sampling tube from the lower opening, only the circular cross-sectional area of ​​the sampling tube is in contact with the sauce in the vertical direction. This reduces the impact of the sampling tube entering the sauce on the sauce's position and meets the requirement of maintaining the original position of the sauce during static sampling. However, when sampling is performed with a sampling tube installed, the working area for stirring the sauce can be expanded, and the sauce can be controlled to enter the corresponding area in the sampling tube after stirring, thus meeting the sampling requirements during the stirring sampling process.

[0042] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0043] like Figure 1 As shown, a sampling device for testing sauce production includes:

[0044] The support frame 1 is placed horizontally above the sauce container, and the support frame 1 is equipped with a sampling mechanism 2 for sampling at different heights near the wall and at the center of the sauce container.

[0045] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the sampling mechanism 2 includes a sliding block 20. Two symmetrical sliding blocks 20 are slidably arranged on the support frame 1. Both the sliding block 20 and the support frame 1 are rotatably connected by a vertical rotating shaft 21. The rotating shaft 21 is connected to an external motor (not shown in the figure). A sampling cylinder 22 with an open bottom is fixedly arranged below the rotating shaft 21. The sampling cylinder 22 has multiple material holes 220 that are equidistantly distributed from top to bottom and penetrate the sampling cylinder 22 from left to right.

[0046] like Figure 1 and Figure 2 As shown, the support frame 1 is provided with a drive group for driving and adjusting the position of the sliding block 20. The two sliding blocks 20 are provided with a fitting group 23 for fitting against the barrel wall. The drive group cooperates with the fitting group 23 to make the left and right sampling cylinders 22 close to the near wall.

[0047] like Figure 2 and Figure 4 As shown, a rotating component 24 is rotatably sleeved on the sampling cylinder 22. The rotating component 24 blocks the material hole 220 when the sample is stationary and makes the material hole 220 open when the sample is stirred.

[0048] like Figure 6 and Figure 7 As shown, a sampling component 25 is installed on the sampling cylinder 22. The sampling component 25 includes a sampling tube 250 and a sealing plate 251. After the sampling component 25 is installed on the sampling cylinder 22, the sealing plate 251 is inserted into the sampling cylinder 22 to seal the sauce in the sampling cylinder 22 at a set height. Then, the sauce at the corresponding height is collected manually at the sampling tube 250 on one side of the sampling cylinder 22.

[0049] like Figure 8 As shown, a stirring blade 26 is fixedly installed on the sampling tube 250.

[0050] Choose either static sampling or stirring sampling based on the type of sauce to be tested, ensuring that the obtained samples are representative enough to meet the testing requirements.

[0051] For the static sampling process: First, the operator adjusts the positions of the left and right sampling cylinders 22 according to the diameter of the sauce container using the drive group and the fitting group 23, ensuring that the two sampling cylinders 22 are in contact with the container wall. Then, the rotating part 24 is rotated to block the material hole 220. At this point, the sauce can only enter through the opening at the lower end of the sampling cylinder 22. Next, the operator vertically lowers the support frame 1, allowing the three sampling cylinders 22 to slowly enter the sauce from top to bottom. The sauce enters the sampling cylinder 22 through the opening at the lower end of the sampling cylinder 22. This method reduces the impact of the sampling process on the sauce. To eliminate interference at the initial position of the sauce, ensure the representativeness of the obtained sample position to meet the required sampling needs. After the sampling action is completed, remove the sampling tube 22. At this time, all samples are located inside the sampling tube 22. Then, rotate the rotating part 24 to install the sampling tube 250 and the sealing plate 251 onto the corresponding sampling tube 22. At this time, the samples inside the sampling tube 22 are divided into multiple areas. Finally, manually remove the samples in the corresponding areas through the sampling tube 250. This completes the sampling process of different heights and different areas in the same sauce container in the static sampling requirement.

[0052] It should be further explained that during static sampling, samples were taken from both the near-wall and center of the sauce container at different heights to obtain multiple samples at different locations and heights. This method is suitable for sampling situations where the sauce is uniformly distributed and for sampling situations when studying the microbial content and volatile components in the sauce.

[0053] For the mixing and sampling process, the operator first rotates the rotating component 24 to open the material hole 220. Then, the sampling tube 250 and the sealing plate 251 are installed on the sampling cylinder 22. At this time, the lower opening of the sampling cylinder 22 is closed, and the sauce can only enter the sampling cylinder 22 through the sampling tube 250. Then, the operator adjusts the positions of the left and right sampling cylinders 22 according to the diameter of the sauce container through the drive group and the bonding group 23, so that the left and right sampling cylinders 22 are close to the container wall. The operator lowers the support frame 1 so that the three sampling cylinders 22 extend into the sauce. The external motor 1 drives the rotating shaft 21 to rotate, and the stirring blade 26 stirs the sauce. After the stirring is completed, the rotating shaft 21 stops rotating, and the sauce enters the corresponding area of ​​the sampling cylinder 22 through the sampling tube 250. The above sampling process is repeated. At this point, the operator takes out the sample from the corresponding area through the sampling tube 250, thus completing the sampling process of different heights and different areas in the same sauce container in the mixing and sampling requirements.

[0054] It should be further explained that after stirring the sauce, samples were taken at different heights near the wall and in the center of the sauce container to obtain multiple samples from different locations. This method is suitable for sampling sauces containing solid particles, spices, or other non-uniformly distributed components, as well as for sampling sauces with stratification. Furthermore, multiple sampling points reduce the impact of insufficient stirring on the test data.

[0055] like Figure 2 and Figure 3 As shown, the drive assembly includes a bidirectional threaded rod 221. Two bidirectional threaded rods 221, which are symmetrically arranged front and back and extend horizontally along their axes, are rotatably passed through the support frame 1. The threaded sections of the bidirectional threaded rods 221 pass through the corresponding sliding block 20 and are threadedly engaged with the sliding block 20. The bidirectional threaded rods 221 are connected to an external motor (not shown in the figure).

[0056] like Figure 1 and Figure 2 As shown, the bonding group 23 includes snap-fit ​​holes 230. Two sets of symmetrical holes are provided through the sliding block 20. Each set of holes includes three snap-fit ​​holes 230 that are equidistant from left to right. An L-shaped snap-fit ​​plate 231 is provided on the upper side of the sliding block 20.

[0057] The lower end face of the snap-fit ​​plate 231 is fixedly provided with an arc-shaped bonding plate 234. The horizontal section of the snap-fit ​​plate 231 is fixedly provided with four rectangular snap-fit ​​posts 232. The bonding plate 234 is installed by snapping the left and right snap-fit ​​posts 232 into the corresponding snap-fit ​​holes 230. The length of the bonding plate 234 is greater than the length of the sampling cylinder 22.

[0058] The distance between the bonding plate 234 and the corresponding sampling cylinder 22 is adjusted by inserting the snap-fit ​​post 232 into different snap-fit ​​holes 230, thereby adapting to both static sampling and stirring sampling requirements.

[0059] During operation, before placing the sampling tube 22 into the sauce container, adjust the position of the bonding plate 234 according to the static sampling and stirring sampling conditions. The specific operation is as follows: When static sampling is required, insert the four locking pins 232 into the four locking holes 230 on the sliding block 20 near the central rotating shaft 21. At this time, the distance between the bonding plate 234 and the adjacent sampling tube 22 is adapted to the static sampling process. That is, when the bonding plate 234 is attached to the outer wall of the sauce container, the corresponding sampling tube 22 is located in the area near the wall. When stirring sampling is required, insert the four locking pins 232 into the four locking holes 230 on the sliding block 20 away from the central rotating shaft 21. At this time, the distance between the bonding plate 234 and the adjacent sampling tube 22 is adapted to the stirring sampling process. That is, when the bonding plate 234 is attached to the outer wall of the sauce container, the corresponding sampling tube 22 is located in the area near the wall.

[0060] It should be further explained that the position of the sampling tube 22 is controlled by cooperating with different locking holes 230 and locking posts 232. When sampling under static conditions, the sampling tube 22 is kept close to the barrel wall. When sampling with stirring, the sampling tube 22 is kept close to the barrel wall while avoiding the problem of the sampling tube 250 colliding with the barrel wall.

[0061] The external motor 2 drives the bidirectional threaded rod 221 to rotate synchronously. Through the threaded engagement between the bidirectional threaded rod 221 and the two sliding blocks 20, the sliding blocks 20 are moved in the left and right directions, and the two sliding blocks 20 move in opposite directions. The sliding blocks 20 drive the bonding plate 234 to move synchronously. When both bonding plates 234 are in contact with the outer wall of the barrel, the middle sampling cylinder 22 is located at the center of the sauce barrel. At this time, the remaining two sampling cylinders 22 are also located directly above the set sampling position. Then the support frame 1 continues to move down. Finally, the support frame 1 is placed above the sauce barrel, the sampling cylinder 22 enters the sauce, and then the sampling process begins.

[0062] like Figure 4 and Figure 5 As shown, a connecting ring 27 is fixedly mounted on the sliding block 20 and rotatably sleeved on the corresponding rotating shaft 21. The lower end of the rotating shaft 21 is connected to the inner cavity of the sampling cylinder 22. A connecting cavity 272 is opened in the connecting ring 27. A connecting groove 270 is opened on the rotating shaft 21 and is connected to the connecting cavity 272. A through pipe 271 is provided on the sliding block 20 and is connected to the connecting cavity 272. The through pipe 271 is connected to an external air pump (not shown in the figure).

[0063] An external air pump extracts air from the sampling cylinder 22 to create a negative pressure environment, preventing the sauce from falling out of the sampling cylinder 22 during the sampling process.

[0064] like Figure 2As shown, the rotating component 24 is composed of multiple rotating cylinders 240 distributed from top to bottom and a guide cylinder 241 at the bottom. The rotating cylinders 240 are connected to each other and to the guide cylinder 241 by L-shaped connecting blocks. The guide cylinder 241 consists of a cylindrical section and a frustum section from top to bottom.

[0065] The process of guiding the rotating component 24 and sampling cylinder 22 into the stationary sauce through the frustum section reduces disturbance to the position of the stationary sauce.

[0066] The rotating component 24 has through holes 242 that correspond one-to-one with the material holes 220.

[0067] like Figure 4 and Figure 5 As shown, a locking assembly 28 is provided on the rotating component 24. The locking assembly 28 includes a toggle plate 280. The toggle plate 280, which is rotatably sleeved on the rotating shaft 21, is fixedly provided on the upper end surface of the rotating component 24.

[0068] The actuating plate 280 is provided with two locking pins 281 that slide up and down. The locking pins 281 and the actuating plate 280 are fixedly provided with a return spring 282 located above the actuating plate 280. The upper end face of the sampling cylinder 22 is provided with a locking groove 283 corresponding to the locking pins 281.

[0069] like Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, the sampling tubes 250 on the same sampling cylinder 22 are opposite each other and symmetrical. The end of the sampling tube 250 near the sampling cylinder 22 is a plug section, and the outer diameter of the plug section is the same as the diameter of the material hole 220.

[0070] The sampling cylinder 22 has insertion slots 252 extending through it from left to right. The rotating cylinder 240 on the same sampling cylinder 22 is offset from the insertion slots 252. To improve the sealing effect of the insertion slots 252 when the sealing plate 251 is not inserted, a rubber sheet (not shown in the figure) is fixedly installed on the inner wall of the insertion slots 252. When the sealing plate 251 is not inserted into the insertion slots 252, the rubber sheet plays a certain role in sealing the insertion slots 252. When the sealing plate 251 is inserted into the insertion slots 252, it automatically pushes open the rubber sheet. The rubber sheet and other existing technologies with the above-mentioned effects can be selected and used by those skilled in the art, and will not be described in detail here. The sealing plate 251 is L-shaped and fixedly sleeved on the sampling tube 250. Two adjacent sealing plates 251 on the same sampling cylinder 22 are symmetrical from left to right. The horizontal section of the sealing plate 251 is inserted into the insertion slot 252 and cooperates with the insertion section of the sampling tube 250 to be inserted into the material hole 220 to complete the insertion and installation of the sampling tube 250.

[0071] After the two adjacent sealing plates 251 on the same sampling cylinder 22 are inserted into the corresponding insertion slots 252, the horizontal sections of the two sealing plates 251 fit together to separate the sauce inside the sampling cylinder 22.

[0072] like Figure 6 , Figure 7 and Figure 8 As shown, the sampling assembly 25 also includes mounting rods 253. Two mounting rods 253 are fixedly installed on the left end face of the horizontal section of the sealing plate 251 on the right side of the same sampling cylinder 22. The two mounting rods 253 are symmetrical and extend from left to right. The other sealing plate 251 is provided with a mounting groove (not shown in the figure) corresponding to the mounting rods 253.

[0073] The mounting rod 253 is provided with a locking groove 283. When the two symmetrical sealing plates 251 are attached to each other, the locking groove 283 is located outside the left sealing plate 251. The locking grooves 283 on the two adjacent mounting rods 253 are jointly installed with locking pins 254.

[0074] like Figure 7 and Figure 8 As shown, a connecting mesh plate 29 is provided through the sealing plate 251 to connect two adjacent areas in the sampling tube 22 after the sealing plate 251 has been sealed. The connecting mesh plate 29 only allows air to flow and prevents a large amount of sauce from flowing through. Furthermore, it should be noted that a small amount of sauce flowing through the connecting mesh plate 29 will not affect the representativeness of the sample.

[0075] Example 1 (for static sampling):

[0076] After adjusting the positions of the three sampling cylinders 22, the sampling tube 250 and the sealing plate 251 are not installed on the sampling cylinder 22, and the rotating part 24 blocks the material hole 220 on the corresponding sampling cylinder 22. The sauce can only be fed upward from the lower opening of the sampling cylinder 22.

[0077] Then, the support frame 1 is slowly lowered manually from top to bottom, so that the three sampling cylinders 22 are slowly squeezed into the sauce. The sauce slowly enters the sampling cylinders 22. When the support frame 1 moves to fit against the top of the sauce container, the required sauce is completely entered into the sampling cylinders 22. During the above process, the external air pump works at the same time to extract the air from the sampling cylinders 22, so that the sauce can enter the sampling cylinders 22. This avoids the air compression caused by the sauce entering the sampling cylinders 22 affecting the distribution of the sauce itself. After the above sampling action is completed, the external air pump stops working, and a sealing system is formed at the top of the sampling cylinders 22. The viscosity of the sauce itself and the sealing effect at the top of the sampling cylinders 22 prevent the sauce from falling out of the sampling cylinders 22. Then, the support frame 1 and the sampling cylinders 22 are moved up manually. It should be noted that a check valve and a buffer bottle (not shown in the figure) are installed between the through pipe 271 and the external air pump. The check valve prevents backflow when the pump stops, and the buffer bottle prevents the sauce from entering the external air pump, thus avoiding blockage of the through pipe 271 and the external air pump, which may affect the sampling process. All of the above uses existing technology. Of course, other measures can also be used, but they will not be elaborated on here.

[0078] The sampling tube 250 and sealing plate 251 are installed manually as follows: First, rotate the rotating part 24 so that the material hole 220 is aligned with the through hole 242, i.e., the material hole 220 is in the open state. The insertion section of the sampling tube 250 is then inserted into the corresponding material hole 220, while simultaneously inserting the corresponding sealing plate 251 into the corresponding insertion slot 252. At this point, the horizontal sections of the two sealing plates 251 cooperate to separate the designated area of ​​the sampling cylinder 22. During this process, the mounting rod 253 is inserted into the mounting slot on the corresponding sealing plate 251 and extends to the outside of the sampling cylinder 22. The locking insertion is then inserted into the corresponding locking slot 283 to complete the sealing. The process of locking and installing plate 251 and sampling tube 250 divides the sauce in sampling cylinder 22 into multiple areas, each corresponding to the required sampling height. Then, an external air pump is used to collect the sauce in each area by connecting the sampling bottle to the corresponding sampling tube 250. This completes the static sampling process. It should be noted that during the sampling process, one sampling tube 250 in a single area is connected to the external air pump, and the other sampling tube 250 is connected to the sampling bottle. The external air pump applies pressure to that area in sampling cylinder 22, causing the sauce to flow into the sampling bottle, thus completing the sampling process. The steps involved in this sampling process are all existing technologies and will not be described in detail.

[0079] Example 2 (for the case of stirring and sampling):

[0080] Before adjusting the positions of the three sampling tubes 22, the sampling tube 250 and the sealing plate 251 are manually installed onto the sampling tube 22 according to the installation method in Embodiment 1 above. Then, the position of the sampling tube 22 is adjusted. At this time, the lower end of the sampling tube 22 is closed, and the sauce can only enter the sampling tube 22 from the sampling tube 250.

[0081] After adjusting the position of the sampling cylinder 22, the support frame 1 is manually moved and placed into the sauce. Simultaneously, an external motor drives the corresponding rotating shaft 21 to rotate synchronously. The rotating shaft 21, through the sampling cylinder 22, drives the sampling tube 250 and stirring blade 26 to rotate synchronously, thus mixing the sauce. During the process of the sauce entering the sampling cylinder 22 and the mixing process, an external air pump continuously pressurizes the inside of the sampling cylinder 22. Combined with the rotational characteristic of the sampling cylinder 22 itself, it is difficult for the sauce to enter the sampling cylinder 22 through the material hole 220 during the mixing process. After the mixing is complete, the external air pump extracts the gas from the sampling cylinder 22 and stops the operation. The sauce in the corresponding height area of ​​the sauce container enters the sampling cylinder 22 through the sampling tube 250 and the material hole 220, completing the sampling process. Then, the sampling cylinder 22 is removed, and the process of removing the corresponding sauce from the sampling cylinder 22 in Example 1 is repeated to complete the sampling process.

[0082] It should be further noted that the effects of air extraction or pressurization using an external air pump in Embodiment 1 and Embodiment 2, as well as the corresponding parameter settings, have been obtained through multiple tests by those skilled in the art, and all meet the required results.

[0083] After the sampled sauce is transferred to a sampling bottle, an ultrasonic sensor is used to detect its layering phenomenon. The sampling bottle is placed on a constant temperature platform, and a miniature ultrasonic probe is placed close to the outer wall of the container with the probe axis perpendicular to the sauce surface. Under the command of the controller, the transmitting unit of the ultrasonic sensor generates a high-frequency electrical signal, which is converted into mechanical vibration and emitted into the sauce. When the ultrasonic wave penetrates the sauce, some of the energy is reflected at the layering interface. The reflected wave is captured by the receiving unit of the ultrasonic sensor during its upward propagation and is then converted into an electrical signal. After filtering and amplification, the electrical signal is transmitted to the analysis system. The layering interface is located by capturing the time difference of the signal by the receiving unit.

[0084] Specifically: If the sauce does not separate into layers, a distinct reflection peak will be generated only on the bottom wall of the container. If the sauce separates into layers, there will be corresponding reflection peaks between the oil phase and the sauce body, between the sauce body and the precipitate, and between the precipitate and the bottom of the sampling bottle. The distance difference between each peak is the thickness of each layer. This is how to detect the separation phenomenon of the sauce.

[0085] Of course, ultrasonic sensors are not the only ones that can detect the layering of sauces; laser sensors or image sensors can also be used to determine the layering of sauces.
