Description

Technical Field

[0001] The present application relates to the technical field of livestock and poultry food detection, and particularly to a residual detector and method for livestock and poultry food. Background Art

[0002] Livestock and poultry food, that is, meat, is one of the common food sources in people's daily lives. However, in recent years, with the high attention paid to food safety issues, problems such as drug residues and veterinary drug residues in meat have gradually become the focus of people's attention. Residual detection, as a key technical means to evaluate the food safety level of livestock and poultry, has become an important step that regulatory agencies and food production enterprises must implement. Using liquid chromatography-tandem mass spectrometry to detect drug residues in meat is a common detection method.

[0003] For example, the patent application with the publication number CN116818968A discloses a detection method and device for veterinary drug residues in animal-derived foods. Regarding the technical field of food veterinary drug residue detection, a detection method for veterinary drug residues in animal-derived foods includes the following steps: tissue pretreatment, sample extraction, and purification of the extraction treatment device. Through the above series of automated steps, this method effectively simplifies the cumbersome traditional pretreatment process, reduces the risk of human operation errors, and also improves work efficiency and detection accuracy.

[0004] However, when using the above patent application for meat detection, there are still the following defects: when pretreating meat tissue, only the meat tissue is chopped and directly put into an acetic acid acetonitrile solution. The internal structure of the meat tissue is not damaged, and there are still gaps between the fibers, which hinders the penetration of the acetic acid acetonitrile solution, resulting in the inability of target components (such as residual drugs and metabolites) to be completely dissolved into the acetic acid acetonitrile solution, and the extraction solution is not representative.

[0005] In the existing detection process, in order to solve the above problems, the meat tissue is also chopped to improve the dissolution efficiency of the target component by fully fusing the meat tissue with the acetic acid acetonitrile solution. However, the particles of the simply chopped meat tissue are still relatively large, and the cell structure is not completely destroyed, resulting in limited solution penetration.

[0006] Based on this, there is still room for improvement in the method for detecting drug residues in meat tissue. Summary of the Invention

In the fixing component designed by the present invention, at the starting position, the fixed rod can be inserted into the meat tissue, and during the grinding process, the fixed rod can fix and limit the meat tissue, avoiding the possibility of the grinding block driving the meat tissue to slip during rotation, resulting in relative sliding between the meat and the grinding block, and improving the grinding effect of the meat tissue.

[0027] 3.

[0038] The following further elaborates on this application with reference to the Figures 1 to 9 accompanying drawings.

[0039] The embodiments of this application disclose a livestock and poultry food residue detector and method, which scrape and grind the minced meat tissue layer by layer, making the internal structure of the meat tissue more thoroughly damaged and ensuring that the meat tissue is more easily soluble in the extraction solution.

[0040] Embodiment 1: Refer to Figure 1A livestock and poultry food residue detector includes a horizontal frame 1, a grinding frame 2 is arranged on the horizontal frame 1, a grinding block 3 matched with the grinding frame 2 is arranged on the top of the grinding frame 2, and a feeding mechanism 4 is arranged on the grinding frame 2.

[0041] The feeding mechanism 4 comprises: There are multiple lifting plates 41 evenly arranged along the circumference of the bottom of the grinding frame 2, and are slidably installed on the bottom of the grinding frame 2. When in the starting position, there is a certain distance between the lifting plate 41 and the bottom of the grinding frame 2, that is, there is a certain space above the lifting plate 41 for placing meat tissue, and the lifting plate 41 and the grinding frame 2 are sealed, that is, the prepared grinding liquid will not leak out from the gap between the lifting plate 41 and the grinding frame 2.

[0042] The lifting assembly 42 is disposed at the bottom of the grinding frame 2 and is used to drive the lifting plate 41 to move along the height direction of the grinding frame 2 .

[0043] The fixing assembly 43 is arranged on the grinding frame 2 and is used for fixing and limiting the meat tissue.

[0044] The lifting plate 41 can be slowly moved upward along the height direction of the grinding frame 2 when driven by the lifting component 42, and then the meat tissue can be driven upward with the cooperation of the fixing component 43, so that the slowly moving upward meat tissue can be ground layer by layer during the rotation of the grinding block 3, avoiding the relative sliding of the meat tissue at the bottom of the grinding block 3, resulting in insufficient grinding of the meat tissue, so that the internal structure of the meat tissue is fully destroyed, thereby ensuring that the extract fully penetrates into the meat tissue.

[0045] Reference Figure 1 as well as Figure 2 A rotating shaft 11 is rotatably mounted on the horizontal frame 1 through a bearing, and the grinding frame 2 is mounted on the top of the rotating shaft 11. An L-shaped fixed frame 12 is provided on the horizontal frame 1. The vertical section of the fixed frame 12 is mounted on the horizontal frame 1. A telescopic rod 13 is rotatably mounted on the horizontal section of the fixed frame 12 through a bearing, and the grinding block 3 is mounted at the bottom of the telescopic rod 13.

[0046] A drive shaft 14 is installed on the horizontal section of the fixed frame 12 through a bearing, and the drive shaft 14 is connected to the telescopic rod 13 through a belt drive. A linkage shaft 15 is installed between the horizontal section of the fixed frame 12 and the horizontal frame 1 through a bearing, a gear 16 is installed on the drive shaft 14, a gear 2 17 meshing with the gear 16 is installed on the linkage shaft 15, and the linkage shaft 15 is connected to the rotating shaft 11 through a belt drive.

[0047] The bottom of the grinding block 3 is set to a rough structure. At the starting position, the grinding block 3 is lifted upward by an external force, so that the grinding block 3 is separated from the grinding frame 2, and there is a gap, ensuring that the meat tissue can be put into the grinding frame 2 through this gap. Specifically, during operation, the minced meat tissue is put into the grinding frame 2. At this time, the external force for lifting the grinding block 3 is removed. After the external force is released, the grinding block 3 moves downward due to gravity. At this time, the telescopic rod 13 moves downward synchronously. It should be noted that the telescopic end of the telescopic rod 13 can only move up and down within its length direction and cannot rotate relatively.

[0048] It should be noted that a limit block is slidably clamped on the linkage shaft 15, and the limit block plays a limiting role on the second gear 17. That is, when the limit block is clamped on the second gear 17, the linkage shaft 15 drives the second gear 17 to rotate synchronously. When the limit block is removed from the second gear 17, the linkage shaft 15 will no longer drive the second gear 17 to rotate synchronously during the rotation process. That is, the drive shaft 14 will no longer drive the linkage shaft 15 to rotate synchronously during the rotation process.

[0049] After the grinding block 3 moves into the grinding frame 2, at this time, the limit block is removed from the second gear 17. During the rotation process of the drive shaft 14, the telescopic rod 13 is driven to rotate synchronously through a belt drive method. During the rotation process of the telescopic rod 13, the grinding block 3 is driven to rotate. Furthermore, during the rotation process of the grinding block 3, the rough structure at its bottom can drive the meat tissue to move synchronously. Furthermore, the bottom of the grinding block 3 can drive the meat tissue to move to the top of the lifting plate 41, so that the meat tissue moves into the space at the top of the lifting plate 41.

[0050] Refer to Figure 3 , a plurality of scraping plates 31 are uniformly arranged along the circumferential direction of the grinding block 3, and the scraping plates 31 slide through the grinding block 3. A ring plate 32 is commonly installed at the top of the scraping plates 31. A return spring rod 33 is commonly installed between the ring plate 32 and the grinding block 3. The threaded rod 34 is installed on the horizontal section of the fixed frame 12 by a threaded connection method, and the bottom of the threaded rod 34 abuts against the ring plate 32.

[0051] And after removing the external force for lifting the grinding block 3, there is a small height gap between the bottom of the grinding block 3 and the inner bottom of the grinding frame 2. The purpose is to leave enough space for the scraping plates 31, that is, to make way for the scraping plates 31. Specifically, during operation, after the meat tissue completely moves into the space at the top of the lifting plate 41, the limit block is reset to be clamped on the second gear 17. And during the downward movement of the grinding block 3, the threaded rod 34 is stationary. At this time, the threaded rod 34 is rotated. The threaded rod 34 rotates and moves downward until it abuts against the ring plate 32. During the rotation and downward movement of the threaded rod 34, the scraping plates 31 are driven to move downward through the ring plate 32 into the gap between the bottom of the grinding block 3 and the inner bottom of the grinding frame 2. At this time, the return spring rod 33 is compressed, and the scraping plates 31 move downward a certain distance through the ring plate 32 and abut against the meat tissue.

[0052] It should be noted that the displacement length of the scraper 31 during movement is also the maximum telescopic length of the telescopic rod 13. That is, when the scraper 31 moves to the gap between the bottom of the grinding block 3 and the inner bottom of the grinding frame 2, the telescopic end of the telescopic rod 13 no longer moves downward. At this time, the telescopic end of the telescopic rod 13 is fixed by existing locking parts (such as bolts, clamps, etc.) to ensure that the telescopic end of the telescopic rod 13 no longer moves up and down.

[0053] After the scraper 31 abuts against the meat tissue, at this time, an external drive motor drives the drive shaft 14 to rotate. During the rotation of the drive shaft 14, the telescopic rod 13 is driven to rotate through a belt drive method. During the rotation of the telescopic rod 13, the scraper 31 is driven to rotate through the grinding block 3. During the rotation of the scraper 31, the surface of the meat tissue can be scraped and ground.

[0054] Refer to Figure 4 and Figure 5 , a through groove 131 is opened inside the telescopic rod 13 (look back Figure 1 ), and a through groove communicating with the through groove 131 is opened on the grinding block 3. A transition groove 21 is opened at the inner bottom of the grinding frame 2, and a plurality of guiding grooves 22 communicating with the transition groove 21 are evenly opened circumferentially at the inner bottom of the grinding frame 2.

[0055] When the scraper 31 scrapes the surface of the meat tissue, an extraction liquid is poured into the telescopic rod 13. The extraction liquid enters the inside of the grinding frame 2 through the through groove 131 and the through groove. At this time, the extraction liquid entering the inside of the grinding frame 2 falls into the transition groove 21. When the extraction liquid in the transition groove 21 reaches a certain depth, the extraction liquid flows towards the inner bottom of the grinding block 3 through the guiding groove 22. Furthermore, the extraction liquid can permeate the inside of the grinding block 3 and fully blend with the meat tissue after being scraped by the scraper 31. Furthermore, the extraction liquid and the scraped meat tissue are mixed to obtain a grinding liquid, and the components inside the meat tissue can be fully dissolved and extracted in the extraction liquid.

[0056] Moreover, during the rotation of the drive shaft 14, the drive shaft 14 drives the linkage shaft 15 to rotate through the meshing of the first gear 16 and the second gear 17. During the rotation of the linkage shaft 15, the rotating shaft 11 is driven to rotate through a belt drive method. During the rotation of the rotating shaft 11, the grinding frame 2 is driven to rotate in the direction opposite to that of the grinding block 3. The rotation directions of the grinding block 3 and the grinding frame 2 are opposite, and the meat tissue in the contact area is simultaneously subjected to clockwise and counterclockwise shearing forces, forming a cross stress network. The superposition of this shear stress can destroy the continuous structure of the muscle fiber bundle. At the same time, the reverse rotation increases the relative movement speed between the meat tissue and the grinding contact surface, and the number of effective frictions per unit time increases, so that the internal structure of the meat tissue is fully damaged, making the meat grinding more thorough.

[0057] The obtained grinding liquid is in the gap between the grinding block 3 and the grinding frame 2. During the rotation of the grinding block 3 and the grinding frame 2, the grinding liquid can be ground for the second time, and the meat tissue inside the grinding liquid can be further ground for the second time, making the grinding effect of the meat tissue better.

[0058] Refer to Figure 6 and Figure 7 , when scraping the meat tissue, it is necessary to move the meat tissue upward so as to always fit with the scraping plate 31. The lifting assembly 42 provided by the present invention can always make the meat tissue move upward at a uniform speed. Specifically, the lifting assembly 42 includes: A lifting sleeve 421, which is installed on the rotating shaft 11 by a threaded connection method, and a limiting protrusion is provided on the side wall of the lifting cylinder.

[0059] A lifting ring 422, which is installed on the lifting sleeve 421 and abuts against the lifting plate 41.

[0060] A limiting rod 423, which is installed on the horizontal frame 1, and the limiting rod 423 slidably penetrates through the limiting protrusion.

[0061] During specific operation, the rotating shaft 11 forms a motion coupling with the lifting sleeve 421 through a threaded pair. When the rotating shaft 11 is driven to rotate, its rotational kinetic energy could originally drive the lifting sleeve 421 to rotate synchronously. However, due to the sliding pair constraint formed by the limiting protrusion provided on the outer side of the lifting sleeve 421 and the limiting rod 423 on the horizontal frame 1, the lifting sleeve 421 can only move axially. Under the screw drive effect of the threaded pair, the rotational motion of the rotating shaft 11 is forced to be converted into the vertical displacement of the lifting sleeve 421, thereby realizing precise linear lifting control. Furthermore, during the movement of the lifting sleeve 421, the lifting ring 422 is driven to move upward, and during the upward movement of the lifting ring 422, the lifting plate 41 is driven to move upward. Moreover, during the upward movement of the lifting plate 41, the meat tissue can be fed upward.

[0062] Among them, the thread pitch in the threaded connection method is small enough to ensure that the moving speed of the lifting sleeve 421 in the vertical direction is slow enough to prevent the feeding speed of the meat tissue from being too fast, resulting in the scraping plate 31 being unable to scrape and process in time.

[0063] Refer to Figure 5 and Figure 6 , the fixing assembly 43 includes: A linkage plate 431, which is slidably arranged inside the lifting plate 41, and as the lifting plate 41 moves upward, the linkage plate 431 moves downward synchronously.

[0064] Fixing rods 432, a plurality of which are uniformly arranged along the length direction of the lifting plate 41, and the fixing rods 432 penetrate through the top of the linkage plate 431 and are installed on the linkage plate 431.

[0065] A plurality of traction rods 433 corresponding to the lifting plates 41 one by one are installed at the bottom of the grinding frame 2, and one end of the traction rod 433 away from the grinding frame 2 is installed on the linkage plate 431.

[0066] During specific operation, during the rotation of the grinding block 3, the meat tissue is sent into the top gap of the lifting plate 41 and inserted into the fixing rod 432 driven by the grinding block 3. At this time, the lifting plate 41 moves upward to feed the meat tissue successively. Due to the fixing effect of the traction rod 433, the linkage plate 431 always remains stationary. Therefore, during the upward movement of the lifting plate 41, the linkage plate 431 always remains in its original position. As the lifting plate 41 moves upward, it can drive the meat tissue to intermittently move out of the fixing rod 432, realizing the successive feeding and removal of the meat tissue.

[0067] Furthermore, through the above steps, the meat tissue can be intermittently fed, so that the meat tissue can be scraped layer by layer by the scraper 31, ensuring that the internal structure of the meat tissue is more thoroughly damaged, and enabling the internal components of the meat tissue to be fully dissolved in the extraction liquid.

[0068] Looking back Figure 4 , an annular groove 23 is formed at the inner bottom of the grinding frame 2, and a plurality of through holes 24 for discharging the grinding liquid are uniformly formed along the circumferential direction inside the annular groove 23.

[0069] Before grinding starts, the through holes 24 are blocked with a sealing plug. After grinding, the obtained grinding liquid flows out from the through holes 24 after passing through the annular groove 23, and finally the grinding liquid is collected.

[0070] Embodiment 2: On the basis of Embodiment 1, when the grinding liquid is prepared, that is, when the top of the lifting plate 41 is flush with the inner bottom of the grinding frame 2, at this time, the threaded rod 34 is continuously rotated to drive the annular plate 32 to move downward. During the downward movement of the annular plate 32, the scraper 31 is driven to move downward and the scraper 31 abuts against the inner bottom of the grinding frame 2. At this time, when the drive shaft 14 drives the telescopic rod 13 to rotate, the grinding block 3 is driven to rotate synchronously. During the rotation of the grinding block 3, the scraper 31 can be driven to scrape the meat tissue attached to the inner bottom of the grinding frame 2, playing a cleaning role.

[0071] During the above process, the limit block is removed to prevent the drive shaft 14 from driving the rotating shaft 11 to rotate through the linkage shaft 15 during rotation, thereby causing the lifting plate 41 to extend out of the inner bottom of the grinding frame 2 and collide with the scraper 31.

[0072] When cleaning the bottom of the grinding block 3, rotate the threaded rod 34 to move it upward. Then, the annular plate 32 drives the scraper 31 to move upward through the reset spring rod 33, causing the bottom of the scraper 31 to retract into the grinding block 3. At this time, drive the rotating shaft 11 to rotate by an external force. During the rotation of the rotating shaft 11, the lifting plate 41 moves upward synchronously until the lifting plate 41 contacts the bottom of the grinding block 3. At this time, during the rotation, the grinding frame 2 drives the lifting plate 41 to scrape the meat tissue adhered to the bottom of the grinding block 3, playing a cleaning role.

[0073] Furthermore, the scraper 31 and the lifting plate 41 cooperate with each other to clean the grinding frame 2 and the grinding block 3, serving multiple purposes with one machine.

[0074] Finally, referring to Figure 9 , the present invention also provides a method for detecting the residue of livestock and poultry food, and its usage method includes the following steps: S1: Put in raw materials, and put the minced meat tissue into the grinding frame 2.

[0075] S2: Grinding preparation, the grinding block 3 moves downward into the grinding frame 2 and abuts against the meat tissue, and an extraction solution is added into the grinding block 3.

[0076] S3: Grinding process, during the rotation of the grinding block 3, the meat tissue is simultaneously sent into the top gap of the lifting plate 41 and inserted into the fixing rod 432 driven by the grinding block 3. At this time, the lifting plate 41 moves upward to feed the meat tissue successively. After the scraper 31 abuts against the meat tissue, at this time, drive the drive shaft 14 to rotate by an external drive motor. During the rotation of the drive shaft 14, drive the telescopic rod 13 to rotate by a belt drive method. During the rotation of the telescopic rod 13, drive the scraper 31 to rotate through the grinding block 3. During the rotation of the scraper 31, the surface of the meat tissue can be scraped and ground.

[0077] S4: Taking material process, after the meat tissue and the extraction solution are ground, the grinding liquid is obtained. The grinding liquid flows out from the through hole 24 after passing through the annular groove 23, and finally the grinding liquid is collected.
