DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0019] Example 1: Reference Figure 1-Figure 7 The figure shows a sample pretreatment device for food processing testing, comprising a support frame 1, an annular guide rail 2, a testing bucket box 3, and a testing and processing box body 4, characterized in that a first testing chamber 11 and a second testing chamber 9 are respectively installed inside the testing and processing box body 4, the connecting ends of the first testing chamber 11 and the second testing chamber 9 are connected to a first guide electric on-off valve 14, a first processing assembly 8 is installed inside the first testing chamber 11, and a second processing assembly 12 is installed inside the second testing chamber 9, a side end of the second testing chamber 9 is connected to a second guide electric on-off valve 15, and a side end of the second guide electric on-off valve 15 is connected to a third processing assembly 7; The annular guide rail 2 is installed on the top of the support frame 1, the detection and processing box 4 is installed on the frame surface of the support frame 1, and the detection bucket box 3 is installed in the outer guide frame of the annular guide rail 2 at equal intervals through guide wheels.

[0020] The first processing component 8 includes a rotating motor 85, a driving motor joint 87, a pneumatic cylinder 88 and a shearing knife 89. The bottom output end of the rotating motor 85 is connected to the driving motor joint 87, the side end of the driving motor joint 87 is connected to the pneumatic cylinder 88, and the shearing knife 89 is installed on the side end of the pneumatic cylinder 88. The edge of the shearing knife 89 is a serrated blade, and the blade angle is 10°.

[0021] The side end of the rotary motor 85 is connected to a vertical sliding seat 86, the side end of the vertical sliding seat 86 is installed with a first operating linear rail 84, the side end of the first operating linear rail 84 is installed with a second operating linear rail 83, and the first operating linear rail 84 and the second operating linear rail 83 form an X-axis and a Y-axis setting respectively.

[0022] A sliding frame 82 is installed on the side end of the second operation linear rail 83 , and the top of the sliding frame 82 is slidably connected to the third operation linear rail 81 . The third operation linear rail 83 is installed on the inner top wall surface of the first detection chamber 11 .

[0023] In this embodiment, first, the food sample to be tested is placed in the detection bucket box 3, and the detection bucket box 3 is distributed equally on the outer guide frame of the annular guide rail 2 through guide wheels. The operator can push the detection bucket box 3 to move along the annular guide rail 2 and move the bucket box containing the sample to the corresponding position above the detection and processing box 4.

[0024] Then in the first detection chamber 11 processing stage; When the detection bucket box 3 containing the sample moves to above the first detection chamber 11 , the first guide electric on-off valve 14 is started to open, and the sample falls into the first detection chamber 11 .

[0025] After that, the first processing component 8 starts to work, so that the rotary motor 85 moves on the first operating linear rail 84 through the vertical sliding seat 86, and adjusts its position in the X-axis direction. At the same time, the first operating linear rail 84 cooperates with the second operating linear rail 83 to realize movement in the X- and Y-axis directions, thereby driving the rotary motor 85 and subsequent components to adjust to the appropriate position. Then the rotary motor 85 is started, and its bottom output end drives the drive motor joint 87 to move. The drive motor joint 87 adjusts the angle and position of the pneumatic cylinder 88 so that the shearing knife 89 is aligned with the sample. Then the pneumatic cylinder 88 pushes the shearing knife 89 to shear the sample. Since the edge of the shearing knife 89 is a serrated blade and the blade angle is set at 10°, it can efficiently cut the food sample, which is convenient for subsequent detection and analysis.

[0026] The sample is then transferred to the second detection chamber 9 stage; After the first processing component 8 is completed, the first guide electric on-off valve 14 is closed, and the second guide electric on-off valve 15 is started to open. The sample that has been preliminarily processed in the first detection chamber 11 enters the second detection chamber 9 through the second guide electric on-off valve 15, so that the second processing component 12 further processes the sample entering the second detection chamber 9 to meet the processing requirements of different detection items for the sample. Then the sample processed by the second detection chamber 9 enters the third processing component 7 through the second guide electric on-off valve 15. The third processing component 7 performs the final processing on the sample and processes the sample into a state suitable for detection. After that, the pre-treated sample is output from the third processing component 7 and can be transported to the corresponding detection equipment for food processing detection, such as component analysis, microbial detection, etc., and after the detection is completed, the first guide electric on-off valve 14 and the second guide electric on-off valve 15 are closed. When the processing requirements of the detection item for the sample change, the first guide electric on-off valve 14 and the second guide can be adjusted by the external PLC controller. The opening timing and time of the electric opening and closing valve 15 change the residence time and flow order of the sample in each processing module, so that when some tests require more refined crushing processing, the sample can stay in the second detection chamber 9 for a longer time, increasing the working time of the second processing component 12, or when new detection requirements arise, the second processing component 12 or the third processing component 7 can be functionally upgraded or replaced, and its working parameters and modes can be adjusted through an external PLC controller to achieve switching between different processing methods to meet diverse detection requirements, so that the overall sample pretreatment process is divided into multiple modules, namely the first detection chamber 11, the second detection chamber 9 and the third processing component 7. Each module undertakes different processing functions. The overall modular setting makes the device more flexible and scalable. Each module can be adjusted or replaced individually according to different detection requirements, reducing manual intervention and greatly shortening the sample pretreatment time, thereby improving the overall detection efficiency, which can meet the needs of large-scale food processing detection while reducing the risk of sample contamination.

[0027] Example 2: According to Figure 4 and Figure 6 As shown, the second processing component 12 includes a high-frequency piezoelectric ceramic controller 123, a telescopic control component 124 and a micro-vibration knife 125. The side end of the high-frequency piezoelectric ceramic controller 123 is connected to the micro-vibration knife 125 at the bottom end of the telescopic control component 124 through a multi-layer piezoelectric stack and a composite electrode.

[0028] An electrical connection joint shaft seat 122 is set at the top of the high-frequency piezoelectric ceramic controller 123, a multi-axis arm section 121 is installed on the side end of the electrical connection joint shaft seat 122, a drive controller 120 is installed on the side end of the multi-axis arm section 121, and the top wall surface of the drive controller 120 is fastened to the internal top wall surface of the second detection chamber 9 through a connecting frame.

[0029] In this embodiment, the drive controller 120 receives instructions from an external PLC controller to control the multi-axis arm section 121 to move. The multi-axis arm section 121 drives the electrically connected joint shaft seat 122 and the high-frequency piezoelectric ceramic controller 123 to move to a suitable position above the sample. Then the high-frequency piezoelectric ceramic controller 123 is started, and the electrical energy is converted into mechanical energy through the multi-layer piezoelectric stack and composite electrodes, driving the telescopic control component 124 to drive the micro-vibrator 125 to vibrate at high frequency. The micro-vibrator 125 further processes the sample under high-frequency vibration, so that for food samples with strong toughness, the high-frequency vibration of the micro-vibrator 125 can be used to more effectively cut or crush them, so as to meet the requirements of different detection items on sample particle size, etc., and can adapt to food samples of different shapes and textures to improve the processing effect.

[0030] Example 3: According to Figure 3 、 Figure 4 and Figure 7 As shown, the third processing assembly 7 includes a third detection chamber 71 , a multi-gear driving structure 73 is installed at the side end of the third detection chamber 71 , and the output end of the multi-gear driving structure 73 is connected to multiple groups of grinding rollers 72 .

[0031] The side end of the support frame 1 is fastened to the liquid nitrogen operation tank 74 through a connecting rod. The side end of the liquid nitrogen operation tank 74 is connected to a delivery pipe 75. The side end of the delivery pipe 75 is connected to a liquid nitrogen spray rotating head 76. The bottom of the third detection chamber 71 is connected to a third guide electric opening and closing valve 16.

[0032] The side end of the third guide electric on-off valve 16 is connected to a semiconductor low-temperature keep-alive conveyor belt 77, and a detection box 78 is installed on the surface of the semiconductor low-temperature keep-alive conveyor belt 77. The inside of the detection box 78 is respectively installed with a digestion microreactor and a magnetic bead enrichment chip.

[0033] A plasma-assisted photocatalytic self-cleaning structure is installed inside the first detection chamber 11, the second detection chamber 9 and the third detection chamber 71. The plasma-assisted photocatalytic self-cleaning structure consists of an atmospheric pressure cold plasma spray gun and a cleaning and discharge cavity.

[0034] A discharge slot plate 10 is provided on the surface of the detection and processing box 4 , a first electric push rack 5 and a second electric push rack 13 are installed on both sides of the first detection chamber 11 , and a third electric push rack 6 is installed on the side end of the second detection chamber 9 .

[0035] In this embodiment, during the above-mentioned treatment process, if it is necessary to clean the residual sample or impurities in the first detection chamber 11, the plasma-coordinated photocatalytic self-cleaning structure can be started to make the atmospheric pressure cold plasma spray out plasma to disinfect and clean the room, and at the same time clean the discharge cavity to discharge the waste. After the treatment is completed, the first electric pushing rack 5 or the second electric pushing rack 13 can push the sample to a specific position as needed for subsequent transfer. Then, after the first treatment stage is completed, the first guide electric opening and closing valve 14 is closed, and the second guide electric opening and closing valve 15 is started to open it. The sample that has been preliminarily processed in the first detection chamber 11 enters the second detection chamber 9 through the second guide electric opening and closing valve 15. The sample after being processed in the second detection chamber 9 enters the third detection chamber 71 through the second guide electric opening and closing valve 15. The multi-gear drive structure 73 is started, and its output end drives multiple sets of grinding rollers 72 to operate to grind the sample and further refine the sample particles. If the sample needs to be further refined, Low-temperature treatment is performed. For example, for some easily oxidized or heat-sensitive samples, the liquid nitrogen in the liquid nitrogen operation tank 74 is transmitted to the liquid nitrogen spray rotary head 76 through the transmission pipe 75. The liquid nitrogen spray rotary head 76 sprays liquid nitrogen into the third detection chamber 71 to lower the indoor temperature and protect the sample from low temperature. When the treatment is completed, the third guide electric on-off valve 16 is opened, and the sample falls into the semiconductor low-temperature preservation conveyor belt 77. The semiconductor low-temperature preservation conveyor belt 77 maintains a low-temperature environment and transports the sample to the detection box 78. After the sample enters the detection box 78, the digestion microreactor digests the sample to fully release the target components in the sample. Then the magnetic bead enrichment chip enriches the target components to facilitate subsequent detection and analysis. The processed sample can be transported to the corresponding detection equipment for food processing detection, such as component analysis, microbial detection, etc. The overall device performs fine processing on the sample according to its respective functions to ensure the consistency of the treatment effect, reduce the workload of manual cleaning, and reduce the risk of cross-contamination of samples.

[0036] The wiring diagram of the rotary motor 85, the drive controller 120, and the high-frequency piezoelectric ceramic controller 123 in the present invention is common knowledge in the field, and its working principle is a well-known technology. The appropriate model is selected according to actual use, so the control method and wiring layout of the rotary motor 85, the drive controller 120, and the high-frequency piezoelectric ceramic controller 123 will not be explained in detail.

[0037] The method of use and working principle of this device are as follows: first, the food sample to be tested is placed in the detection bucket box 3, which is evenly distributed on the outer guide frame of the annular guide rail 2 through the guide wheels. The operator can push the detection bucket box 3 to move along the annular guide rail 2, and move the bucket box containing the sample to the top of the corresponding position of the detection and processing box 4. When the detection bucket box 3 containing the sample moves to the top of the first detection chamber 11, the first guide electric opening and closing valve 14 is started to open it, and the sample falls into the first detection chamber 11. Then the first processing component 8 starts to work, so that the rotary motor 85 moves on the first operation linear rail 84 through the vertical sliding seat 86, adjusts its own position in the X-axis direction, and at the same time, the first operation linear rail 84 is connected to the second The cooperation of the operating linear rail 83 realizes the movement in the X and Y axis directions, thereby driving the rotary motor 85 and subsequent components to adjust to the appropriate position, and then the rotary motor 85 is started, and its bottom output end drives the driving motor joint 87 to move, and the driving motor joint 87 adjusts the angle and position of the pneumatic cylinder 88 to align the shearing knife 89 with the sample, and then the pneumatic cylinder 88 pushes the shearing knife 89 to shear the sample. Since the edge of the shearing knife 89 is a serrated edge and the blade angle is set at 10°, it can efficiently cut the food sample, which is convenient for subsequent detection and analysis. After the first processing component 8 is completed, the first guide electric on-off valve 14 is closed, and the second guide electric on-off valve 15 is started to open it. The sample that has been preliminarily processed in the first detection chamber 11 passes through the second The electric opening and closing valve 15 is guided to enter the second detection chamber 9, so that the second processing component 12 further processes the sample entering the second detection chamber 9, that is, the driving controller 120 receives the external PLC controller instruction and controls the multi-axis arm section 121 to move. The multi-axis arm section 121 drives the electric joint shaft seat 122 and the high-frequency piezoelectric ceramic controller 123 to move to a suitable position above the sample. Then the high-frequency piezoelectric ceramic controller 123 is started, and the electrical energy is converted into mechanical energy through the multi-layer piezoelectric stack and the composite electrode, and the telescopic control component 124 is driven to drive the micro-vibration knife 125 to vibrate at high frequency. The micro-vibration knife 125 further processes the sample under high-frequency vibration, so that for food samples with strong toughness, the high-frequency vibration of the micro-vibration knife 125 can be more effective. The sample is chopped or crushed to meet the requirements of different test items on sample particle size, etc., and can adapt to food samples of different shapes and textures to improve the processing effect. Then, the sample processed by the second detection chamber 9 enters the third processing component 7 through the second guide electric opening and closing valve 15, so that the multi-gear drive structure 73 is started, and its output end drives multiple sets of grinding rollers 72 to operate to grind the sample and further refine the sample particles. If the sample needs to be processed at a low temperature, such as for some easily oxidized or heat-sensitive samples, the liquid nitrogen in the liquid nitrogen operation tank 74 is transmitted to the liquid nitrogen spray rotating head 76 through the delivery pipe 75. The liquid nitrogen spray rotating head 76 sprays liquid nitrogen into the third detection chamber 71 to lower the indoor temperature and protect the sample at a low temperature. When the processing is completed,The third guide electric on-off valve 16 is opened, and the sample falls into the semiconductor low-temperature keep-alive conveyor belt 77. The semiconductor low-temperature keep-alive conveyor belt 77 maintains a low-temperature environment and transports the sample to the detection box 78. After the sample enters the detection box 78, the digestion microreactor digests the sample to fully release the target components in the sample. The magnetic bead enrichment chip then enriches the target components for subsequent detection and analysis. The processed sample can be transported to the corresponding testing equipment for food processing testing, such as component analysis and microbiological testing. After the test is completed, the first guide electric on-off valve 14 and the second guide electric on-off valve 15 are closed.
