Description

Technical Field

[0001] This utility model relates to the field of pork testing technology, and in particular to an integrated device for pork sample preservation and component determination. Background Technology

[0002] As a major meat product consumed globally, pork quality directly impacts food safety and public health. Testing can accurately assess moisture, fat, protein content, and spoilage indicators (such as TVB-N and microorganisms) to ensure compliance with hygiene standards, prevent foodborne illnesses, and allow for the tracing of issues in the breeding and processing stages, thus optimizing supply chain management. This is crucial for protecting consumer rights, regulating market order, and promoting the high-quality development of the meat industry.

[0003] Samples are prone to deterioration during storage and testing due to temperature fluctuations, microbial growth, or oxidation, leading to distorted test results. Manually opening the sample box during testing is time-consuming, and the risk of sample exposure to environmental temperature and humidity and microbial contamination increases during exposure, especially with accelerated spoilage under high temperature conditions, affecting the repeatability and reliability of the test. To address these issues, we propose an integrated device for pork sample preservation and component determination. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing an integrated device for pork sample preservation and component determination.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated device for pork sample preservation and component determination, comprising a motor, a second motor, a detection box, a base, a sample box, a travel frame, and a cleaning box. The detection box is mounted on the upper end of the base. A travel frame is located inside the detection box, and the sample box is located inside the travel frame. Symmetrically distributed opening and closing lids are mounted on the upper end of each opening and closing lid. Pressure bottle one and pressure bottle two are respectively mounted on the upper end of each opening and closing lid. A connecting block is mounted on one end of each opening and closing lid, and a rotating shaft is mounted on one end of each connecting block. Symmetrically distributed rotating parts that rotate with the rotating shaft are mounted on the outer wall of the sample box. The installed bearing housing has an arc-shaped guide rail on the outer wall of the rotating shaft. The inner wall of the detection box has symmetrically distributed support rods corresponding to the guide rails. The detection box contains a detection component one, which includes near-infrared spectroscopy, Raman spectroscopy, and fluorescence sensors. The upper end of the detection box has a motor two. The output end of the motor two has a rotating plate rotatably installed inside the detection box. The rotating plate contains a hydraulic rod two and a detection component two. The lower end of the hydraulic rod two has a detection end electrically connected to the detection component one. The outer side of the rotating shaft is fitted with a torsion spring with both ends connected to the center block and the bearing housing, respectively.

[0006] Preferably, a ball bearing is rotatably mounted inside one end of the support rod and is rolled on the inner wall of the guide rail. The ball bearing reduces friction and resistance when the support rod is compressed, and forces the rotating shaft to overcome the torsional elasticity of the torsion spring by compressing the guide rail, and rotates through the bearing seat.

[0007] Preferably, the front end of the testing chamber is equipped with a display panel, the first pressure bottle stores a mixed protective gas, the second pressure bottle stores liquid nitrogen, and both the first and second pressure bottles have valve-controlled output pipes located inside the testing chamber at their lower ends. The display panel displays the testing data, and the protective gas and liquid nitrogen are stored separately. The protective medium is delivered to preserve the pork samples according to the required transportation distance.

[0008] Preferably, a motor is mounted on the upper end of the base, a screw is mounted on the output end of the motor, a nut is threaded onto the outer wall of the screw, a guide rail is mounted on the upper end of the base, a slider is slidably mounted on the guide rail at the lower end of the nut, the upper end of the nut is connected to a travel frame, and a bearing bracket is rotatably mounted on the upper end of the base to the screw. The driving force of the motor drives the screw to push the nut, and the nut, guided by the slider, moves laterally. When the screw rotates, one end receives rotational support through the bearing bracket.

[0009] Preferably, a positioning block is provided at one end of the sample box, and a positioning plate is provided at the upper end of the sample box. A positioning groove is formed inside one end of the positioning plate to engage with the positioning block. The sample box is positioned by inserting the positioning block into the positioning groove.

[0010] Preferably, the travel frame is internally equipped with symmetrically distributed hydraulic rods, and the telescopic end of each hydraulic rod is fitted with a clamping plate that fits against the sample box. The hydraulic rods drive the clamping plate to clamp the positioned sample box, ensuring stability during the sample box testing and transport process.

[0011] Preferably, the testing chamber contains a cleaning box, with a water pump and a hot air blower on either side. Inside the cleaning box is a first ring pipe connected to the water pump's output. Below the first ring pipe is a second ring pipe connected to the hot air blower's output. The inner wall of the first ring pipe has a first nozzle arranged in a circular array, and the inner wall of the second ring pipe has a second nozzle arranged in a circular array. A discharge pipe is located at the lower end of the cleaning box. The first and second ring pipes inside the cleaning box deliver cleaning water to clean and dry the testing end, and wastewater is discharged through the discharge pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention involves placing pork samples inside a sampling box. The opening and closing control of the top of the sampling box is supported by a torsion spring. During transportation, a 30% CO2 + 70% N2 mixed gas is introduced to inhibit the growth of aerobic bacteria, making it suitable for short-term preservation. The sampling box is directly immersed in liquid nitrogen, making it suitable for long-distance transportation and for long-term stability studies of nucleic acids and proteins. The detection process is automated through contact and non-contact methods. The non-contact detection device uses near-infrared spectroscopy to quickly scan moisture / fat, Raman spectroscopy to analyze protein structure, and a fluorescence sensor to detect spoilage markers. The contact detection device uses an electrochemical sensor that contacts the sample surface through an automatic insertion mechanism to accurately measure sensitive indicators such as TVB-N and pH value. After completion, the probe self-cleans. The opening and closing cover automatically opens during the detection process, shortening preparation time and ensuring that the meat quality is effectively and accurately detected during preservation.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-5 As shown, this utility model proposes an integrated device for pork sample preservation and component determination, including a motor 1, a motor 4, a detection box 5, a base 6, a sample box 8, a travel frame 9, and a cleaning box 13. The detection box 5 is mounted on the upper end of the base 6. The travel frame 9 is installed inside the detection box 5, and the sample box 8 is installed inside the travel frame 9. Symmetrically distributed opening and closing covers 18 are provided on the upper end of the sample box 8.

Symmetrically distributed bearing seats that are rotatably mounted with the rotating shaft 20 are provided on the outer wall of the sample box 8. 24. An arc-shaped guide rail 23 is provided on the outer wall of the rotating shaft 20. Symmetrically distributed support rods 14 corresponding to the guide rail 23 are provided on the inner wall of the detection box 5. A detection component 2 is installed inside the detection box 5, including near-infrared spectroscopy, Raman spectroscopy, and fluorescence sensors. A motor 4 is installed at the upper end of the detection box 5. A rotating plate 29, rotatably mounted inside the detection box 5, is provided at the output end of the motor 4. A hydraulic rod 31 and a detection component 30 are installed inside the rotating plate 29. A detection end 38, electrically connected to the detection component 2, is provided at the lower end of the hydraulic rod 31. A torsion spring 25, with its two ends connected to the center block and bearing seat 24 respectively, is sleeved on the outer side of the rotating shaft 20.

[0022] One end of the support rod 14 has a ball bearing 26 that is rotatably mounted on the inner wall of the guide rail 23;

[0023] The front end of the detection chamber 5 is equipped with a display panel 3. Pressure bottle 19 contains mixed protective gas, and pressure bottle 21 contains liquid nitrogen. Both pressure bottle 19 and pressure bottle 21 have an output pipe located inside the detection chamber 5 and controlled by a valve at their lower ends.

[0024] A motor 1 is installed on the upper end of the base 6. A screw 12 is installed at the output end of the motor 1. A nut 10 is installed on the threaded outer wall of the screw 12. A guide rail 23 is installed on the upper end of the base 6. A slider 11 is installed at the lower end of the nut 10 and is slidably installed with the guide rail 23. The upper end of the nut 10 is connected to the stroke frame 9. A bearing bracket 7 is installed on the upper end of the base 6 and is rotatably installed with the screw 12.

[0025] A positioning block 17 is provided at one end of the sample box 8, and a positioning plate 15 is provided at the upper end of the sample box 8. A positioning groove 16 is provided inside one end of the positioning plate 15 to engage with the positioning block 17.

[0026] The travel frame 9 is equipped with symmetrically distributed hydraulic rods 27 inside, and the telescopic end of the hydraulic rods 27 is equipped with a clamping plate 28 that fits against the sample box 8.

[0027] The testing box 5 is equipped with a cleaning box 13. A water pump 33 and a hot air blower 36 are respectively installed on both sides of the cleaning box 13. A first ring pipe 34 connected to the output end of the water pump 33 is installed inside the cleaning box 13. A second ring pipe 37 connected to the output end of the hot air blower 36 is installed below the first ring pipe 34. A first nozzle 32 arranged in a ring array is installed on the inner wall of the first ring pipe 34. A second nozzle 39 arranged in a ring array is installed on the inner wall of the second ring pipe 37. A discharge pipe 35 is installed at the lower end of the cleaning box 13.

[0028] Based on the implementation steps of Example 1: Place the pork sample in the sample box 8, close the opening and closing lid 18, and start the pressure bottle 19 (containing a mixture of 30% CO2 and 70% N2 gas) or the pressure bottle 21 (liquid nitrogen) according to the transportation requirements. During short-term transportation, the mixed gas is injected into the sample box 8 through the output pipe to inhibit the activity of aerobic bacteria; during long-term transportation, liquid nitrogen is released to quickly cool down, freeze the microbial metabolism, and avoid protein denaturation.

[0029] CO2 lowers the pH value to inhibit putrefactive bacteria, N2 replaces oxygen to delay fat oxidation, and liquid nitrogen at ultra-low temperature blocks enzyme activity and water migration. The dual-mode system adapts to different scenario requirements. The starting motor 1 drives the screw 12 to rotate, which in turn drives the nut 10 and the travel frame 9 to move laterally along the guide rail 23. The hydraulic rod 27 pushes the clamping plate 28 to hold the sample box 8, ensuring stable transportation. The positioning block 17 fits into the positioning groove 16 to accurately align with the entrance of the detection box 5. Mechanical transmission replaces manual handling. After the sample box 8 enters the detection box 5, the support rod 14 slides along the arc-shaped guide rail 23 of the rotating shaft 20 through the ball bearing 26, squeezing the rotating shaft 20 to overcome the elastic force of the torsion spring 25 and rotate. The opening and closing cover 18 flips open in a very short time.

[0030] The torsion spring 25's elastic reset design ensures automatic closure after opening, reducing sample exposure time. The ball bearing 26 reduces friction and improves the durability of the mechanism. The motor 24 drives the rotating plate 29 to adjust the angle. Near-infrared spectroscopy scans the sample surface, analyzing the moisture and fat content through absorption peaks. Raman spectroscopy (532nm laser) identifies the characteristic peaks of protein amide bonds. A fluorescence sensor (ultraviolet excitation) captures the fluorescence signals of putrefactive substances such as TVB-N, enabling rapid initial screening.

[0031] Hydraulic rod 2 31 presses down the detection end 38, and the electrochemical sensor (such as a three-electrode system) is inserted into the sample surface to measure the current response of TVB-N and the pH glass electrode potential value. The probe automatically retracts after contact. Loop tube 1 34 is sprayed with deionized water for cleaning, and loop tube 2 37 is dried with hot air to avoid cross-contamination.

[0032] After the test is completed, the water pump 33 starts, and the ring pipe 34 sprays cleaning fluid through the nozzle 32 to rinse the residue on the surface of the test end 38. The hot air blower 36 delivers 60°C hot air through the ring pipe 37 and the nozzle 39 for rapid drying. The wastewater is discharged through the discharge pipe 35. The hydraulic rod 27 releases the clamp 28, and the motor 1 reverses to drive the travel frame 9 back to its original position. The opening and closing cover 18 is reset and closed by the torsion spring 25, ready for the next round of testing. Through the dynamic preservation of mixed gas / liquid nitrogen and the automatic opening design, the sample exposure time is greatly shortened, avoiding microbial contamination and oxidation caused by manual opening in traditional testing, and ensuring the authenticity of the data.

[0033] Non-contact spectroscopy technology can complete multi-index screening within 5 minutes, while contact sensors can perform point verification within 2 minutes, improving efficiency compared to manual operation. Multi-sensor data fusion reduces the limitations of single technologies, such as insufficient penetration of NIR for dark samples. Mechanical linkage and electronic control systems replace manual sample sorting, opening, and cleaning, making it suitable for high-hygiene scenarios such as sterile laboratories and online quality inspection on slaughter lines, reducing human error and biosafety risks. By replacing detection components, such as replacing biosensor chips and upgrading the software database, it can be expanded to the detection of beef, mutton, and aquatic products, meeting the needs of multiple species. Cloud data traceability supports supply chain quality supervision, solving the pain points of traditional testing such as easy sample deterioration, cumbersome operation, and poor timeliness. It provides food processing and third-party testing institutions with low-cost, high-precision meat quality inspection.
