Abstract
Description
Technical Field
[0001] This application relates to the field of food testing technology, and in particular to a sample processing device for food testing. Background Technology
[0002] Food testing primarily relies on fundamental theories and techniques of physics, chemistry, and biochemistry to inspect the quality of food raw materials, auxiliary materials, semi-finished products, finished products, and by-products according to relevant technical standards to ensure product quality compliance. When testing meat samples, pretreatment is often necessary to better release the analytes. For example, when testing meat, fat, bones, and tendons are removed from the sample. The meat is then chopped, a certain amount is weighed, and placed in an Erlenmeyer flask. Pure water is added to immerse the meat sample, allowing the analytes to be released.
[0003] Since the sample volume for testing is usually not large, manually chopping meat samples with knives is not only inefficient but also carries the risk of cutting fingers. Therefore, there is an urgent need for a device that can safely and efficiently process meat samples. Utility Model Content
[0004] This application provides a sample processing device for food testing, which can safely and efficiently process meat samples during food testing.
[0005] The above-mentioned objective of this application is achieved through the following technical solution:
[0006] A sample processing device for food testing includes a sample processing table, with a support leg integrally formed at each of the four lower corners of the sample processing table, and a horizontally placed mounting frame provided on the upper side of the sample processing table. A grid cutter is embedded in the mounting frame, and the blades in the grid cutter are arranged in a crisscross pattern.
[0007] A vertical guide rod is provided on one of the opposite sides of the sample processing stage. A slider is fitted on each guide rod and the two are slidably connected in the vertical direction. The opposite sides of the two sliders are fixedly connected to the mounting frame.
[0008] The lower ends of both guide rods are fixedly connected to the sample processing stage via an extension rod.
[0009] Furthermore, a groove is provided on the upper side of the sample processing stage, and one side of the groove on the sample processing stage is open in the circumferential direction. A support plate that can freely enter and exit from its open end is placed in the groove on the sample processing stage. A cutting plate is integrally formed on the upper side of the support plate. The cutting plate is provided with multiple cutting grooves corresponding to the crisscrossing blades in the grid cutter. The blades in the grid cutter can be inserted into the cutting grooves of the cutting plate in the vertical direction.
[0010] Furthermore, a return spring is sleeved on the guide rod, the lower end of the return spring is fixedly connected to the upper side of the lower end of the extension rod, the upper end of the return spring is fixedly connected to the annular end panel, the annular end panel is movably sleeved on the guide rod, and the slider on the corresponding side is located on the upper side of the annular end panel.
[0011] Furthermore, a handle is fixedly connected to each of the two sliders on their opposite sides.
[0012] Furthermore, a groove is provided on the inner side of each opposite sidewall of the mounting frame, and a protrusion is provided on the outer side of each opposite sidewall of the grille cutter. An opening is provided on one side of the mounting frame near one end of the groove. When the grille cutter enters and exits from the opening of the mounting frame, the protrusion can slide freely on the groove on the corresponding side.
[0013] Furthermore, a cover plate is placed on the upper side of the mounting frame, and a plurality of extrusion rods are fixedly connected to the lower side of the cover plate. The number of extrusion rods is equal to the number of holes between the crisscrossing blades on the grid cutter, and the position of the extrusion rods on the cover plate corresponds one-to-one with the position of the holes between the blades on the grid cutter.
[0014] Furthermore, a first handle is installed on the outer side of one end of the grating cutter located at the opening of the mounting frame, and a second handle is installed on the outer side of one end of the support plate located at the groove opening on the sample processing stage.
[0015] Furthermore, the upper ends of both guide rods are dome-shaped.
[0016] In summary, this application includes at least one of the following beneficial technical effects:
[0017] After placing the meat sample to be tested on the sample processing table of this application, the experimenter holds the mounting frame equipped with the grid blades and presses it down along the guide rod until the blades in the grid blades pass through the meat sample and contact the sample processing table. At this point, the meat sample on the sample processing table is automatically divided into multiple small pieces by the crisscrossing blades in the grid blades, thus achieving the effect of chopping the meat sample. Because the device of this application only requires the experimenter to place the meat sample on the sample processing table and press down on the mounting frame with both hands, the internal grid blades can quickly cut the meat sample into multiple small pieces. Compared with existing technologies, this not only significantly improves the processing efficiency of meat samples, but also significantly enhances safety during the cutting process because the experimenter's hands are positioned above the grid blades.

Detailed Implementation
[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.
[0024] like Figure 1 and Figure 2 As shown, this application discloses a sample processing device for food testing, including a sample processing table 1. Each of the four corners of the sample processing table 1 has an integrally formed support leg 2. A horizontally placed mounting frame 3 is provided on the upper side of the sample processing table 1. A grid cutter 4 is embedded within the mounting frame 3, with blades arranged in a crisscross pattern within the grid cutter 4. A vertical guide rod 5 is provided on one of the opposite sides of the sample processing table 1. A slider 6 is fitted onto each guide rod 5, and the two are slidably connected in the vertical direction. The opposite sides of the two sliders 6 are fixedly connected to the mounting frame 3. The lower ends of the two guide rods 5 are fixedly connected to the sample processing table 1 via an extension rod 7.
[0025] In the above embodiments, the sample processing table 1 supported on the experimental table by the support leg 2 can be used to place meat samples to be processed. The grid knife 4 embedded in the mounting frame 3 above the sample processing table 1 has multiple intersecting blades. There are multiple rectangular holes between these intersecting blades. In this way, when the grid knife 4 cuts the meat sample on the sample processing table 1, it can quickly divide the meat sample into multiple small pieces no larger than the holes in the blades of the grid knife 4.
[0026] The guide rods 5 installed on both sides of the sample processing table 1 in this application can provide guidance for the grid cutter 4 as it moves down with the mounting frame 3, so that the grid cutter 4 can quickly complete the cutting action on the meat sample.
[0027] When testing meat samples, researchers typically require approximately 10g of meat to extract the effective substances. However, when chopping these small samples with a knife, it's easy to injure one's fingers. Furthermore, to obtain uniform pieces, researchers need to change the direction of the knife multiple times, leading to low processing efficiency. In contrast, the device described in this application only requires laying the meat sample on the sample processing table 1. Then, holding the mounting frame 3 with both hands, the device is quickly lowered under the guidance of the guide rod 5 until the blades in the grid cutter 4 separate the meat sample. Multiple small pieces are automatically cut on the sample processing table 1. Compared to existing technologies, this application significantly improves the efficiency of meat sample processing. Moreover, during the cutting process, the researcher's hands are positioned outside the mounting frame 3, minimizing the probability of contact with the blades in the grid cutter 4. This significantly reduces the risk of accidental hand injuries, ensuring the researcher's safety when handling meat samples.
[0028] Furthermore, such as Figure 2 and Figure 3As shown, a groove is provided on the upper side of the sample processing stage 1, and one side of the groove on the sample processing stage 1 is open. A support plate 8 that can freely enter and exit from its open end is placed in the groove on the sample processing stage 1. A cutting plate 9 is integrally formed on the upper side of the support plate 8. The cutting plate 9 is provided with multiple cutting grooves 10 corresponding to the crisscrossing blades in the grid cutter 4. The blades in the grid cutter 4 can be inserted into the cutting grooves 10 of the cutting plate 9 in the vertical direction.
[0029] In the above embodiments, the groove provided on the sample processing stage 1 in this application, as described above, not only facilitates the installation of the support plate 8 on the sample processing stage 1, but also facilitates the removal of the support plate 8 from the groove in the horizontal direction. The cutting plate 9 on the support plate 8 is provided with multiple cutting grooves 10 that intersect with those in the grid cutter 4. In this way, when the grid cutter 4 cuts the meat sample downwards on the cutting plate 9, the part of the meat sample above the cutting grooves 10 is in a suspended state and is more easily cut by the blade in the grid cutter 4 due to stress concentration, thereby ensuring the cutting effect when this application is used.
[0030] Furthermore, such as Figure 2 As shown, a return spring 11 is sleeved on the guide rod 5. The lower end of the return spring 11 is fixedly connected to the upper side of the lower end of the extension rod 7. The upper end of the return spring 11 is fixedly connected to the annular end panel 12. The annular end panel 12 is movably sleeved on the guide rod 5, and the corresponding slider 6 is located on the upper side of the annular end panel 12.
[0031] In the above embodiments, the return spring 11, which is set on the guide rod 5 in the manner described above, can generate a certain resistance to the mounting frame 3 when the experimenter presses it down, so that the experimenter can better control the downward movement speed of the mounting frame 3. After the grid cutter 4 on the mounting frame 3 has finished cutting the meat sample on the cutting plate 9, the experimenter releases his hand, and the return spring 11 can use its elasticity to help the entire mounting frame 3 return to its initial state along the guide rod 5 (in the initial state, there is a certain gap between the mounting frame 3 and the cutting plate 9, which facilitates the experimenter to observe the meat sample and take off and put away the cutting plate 9), making it more convenient to use.
[0032] Furthermore, such as Figure 2 As shown, a handle 13 is fixedly connected to the two sliders 6 on their opposite sides.
[0033] In the above embodiments, the grips 13 on the two sliders 6 can provide a comfortable grip area for the experimenter's operation, so that the experimenter can better exert force to drive the mounting frame 3 to move.
[0034] Furthermore, such as Figure 3As shown, a groove 14 is provided on the inner side of each opposite sidewall of the mounting frame 3, and a protrusion 15 is provided on the outer side of each opposite sidewall of the grille cutter 4. An opening is provided on one side of the mounting frame 3 near one end of the groove 14. When the grille cutter 4 enters and exits from the opening of the mounting frame 3, the protrusion 15 can slide freely on the groove 14 on the corresponding side.
[0035] In the above embodiments, in order to facilitate subsequent cleaning and disinfection of the grid cutter 4, this application makes the grid cutter 4 and the mounting frame 3 detachably connected. In use, the grid cutter 4 is located inside the mounting frame 3, and the two protrusions 15 on the grid cutter 4 are respectively embedded in the two side grooves 14 inside the mounting frame 3. In this way, the grid cutter 4 will not fall off when the mounting frame 3 moves in the vertical direction. When it is necessary to clean the grid cutter 4, the experimenter can pull out the grid cutter 4 as a whole from the opening of the mounting frame 3 along the groove 14.
[0036] Furthermore, such as Figure 2 and Figure 3 As shown, a cover plate 16 is placed on the upper side of the mounting frame 3, and multiple extrusion rods 17 are fixedly connected to the lower side of the cover plate 16. The number of extrusion rods 17 is equal to the number of holes between the crisscrossing blades on the grid cutter 4, and the position of the extrusion rods 17 on the cover plate 16 corresponds one-to-one with the position of the holes between the blades on the grid cutter 4.
[0037] In the above embodiments, when the grating blade 4 cuts the meat sample, the surface of the meat sample has a certain viscosity, making it easy to penetrate into the gaps between the blades in the grating blade 4. Therefore, after cutting the meat sample, the experimenter can press the cover plate 16 above the mounting frame 3, which can cause the multiple extrusion rods 17 under the cover plate 16 to clear the gaps in the grating blade 4, reducing the loss of the meat sample during the cutting process and the workload of cleaning the grating blade 4 afterwards.
[0038] Furthermore, such as Figure 1 and Figure 3 As shown, a first handle 18 is installed on the outer side of one end of the grid cutter 4 at the opening of the mounting frame 3, and a second handle 19 is installed on the outer side of one end of the support plate 8 at the opening of the groove on the sample processing stage 1.
[0039] In the above embodiments, the first handle 18 provided on the grid cutter 4 facilitates the experimenter to remove the grid cutter 4 from the mounting frame 3, and the second handle 19 provided on the support plate 8 facilitates the experimenter to remove the support plate 8 from the sample processing stage 1.
[0040] Furthermore, such as Figure 1 and Figure 3 As shown, the upper ends of both guide rods 5 are domes.
[0041] In the above embodiments, the upper end of the guide rod 5 of this application is designed as a dome structure, so that when the test personnel put the slider 6 on the mounting frame 3 onto the guide rod 5, it is convenient for the guide rod 5 to be quickly inserted into the slider 6, thereby improving the installation efficiency.
[0042] The implementation principle of this embodiment is as follows: When processing pre-sampled meat samples before testing meat products, the experimenter first uses the second handle 19 to pull the support plate 8 out of the groove on the sample processing table 1. Then, the meat sample is spread out on top of the cutting plate 9 on the support plate 8, and the support plate 8 is pushed back into the groove on the sample processing table 1. Next, the experimenter holds both handles 13 and presses the mounting frame 3 downwards. After the grid blade 4 inside the mounting frame 3 penetrates the meat sample and inserts into the cutting groove 10 on the cutting plate, the experimenter releases their hands. The return spring 11 on the guide rod 5 automatically drives the mounting frame 3 to reset. After the mounting frame 3 resets vertically, there is a gap between it and the cutting plate 9. At this time, the experimenter can use the second handle 19 to remove the support plate 8 from the groove at the top of the meat sample processing table 1. After pouring down the meat sample fragments cut on the surface of the cutting plate 9 on the support plate 8, the subsequent testing work can continue. Compared with the prior art, this not only improves the processing efficiency of meat samples but also reduces the risk of hand injury to the experimenter when cutting meat samples.
[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
