Description

Technical Field

[0001] This disclosure relates to the field of food environmental testing equipment technology, and in particular to a multi-dimensional environmental testing equipment for extending the shelf life of food. Background Technology

[0002] To extend the shelf life of food, it is often necessary to conduct trace detection, micro-detection, and micro-element analysis on the food. This necessitates the use of food environmental testing equipment to conduct safety testing on the food itself and the environment in which the food is processed.

[0003] Patent application CN201810322384.7 discloses an automatic food microbial content detector. The detector separates the operation and detection areas using an operating box and a constant temperature chamber. The independent enclosed space effectively prevents interference from other microorganisms. Before detection, samples are collected using three luminescent tubes and clamped in place by a clamping mechanism, eliminating the need for manual handling. This allows for multiple simultaneous tests, and the accuracy of the tests is ensured through comparison, reducing labor costs. When adding the buffer solution and fluorescein mixture, it can be placed directly inside the collection port, and both are forced in simultaneously using a squeezing method. This method significantly reduces labor, decreases the probability of errors, and improves detection accuracy by allowing the light-emitting tubes to enter the internal structure. Upon entering the detection chamber, the motor causes the entire structure to reciprocate, ensuring uniform mixing. Furthermore, the light-emitting tubes are sealed before entry to facilitate rapid detection. Patent application CN202210176653.X discloses a food fluorescence detection device that uses a micro-motor to drive a rotating chassis, which in turn rotates the outer casing, thus fully dispersing the sample within the test tube and ensuring the accuracy and reliability of the detection results. This method changes the traditional... This manual sample handling method eliminates the need for manual shaking to evenly distribute the sample within the test tube, effectively preventing the tubes from slipping or falling. Furthermore, this method provides more even force compared to manual operation, avoiding damage from excessive shaking and maximizing the preservation of the test tube's structural integrity. During sample handling, the test tube remains within the confined enclosure, minimizing prolonged contact with the external environment and reducing the chance of contact with airborne microorganisms and dust, thus further improving the accuracy of fluorescence detection results. The sample holding device utilizes a locking mechanism. By connecting to a fluorescence detector, the food sample remains within the detector's main body throughout the entire process, from sample processing to fluorescence detection. This prevents confusion between multiple food samples and ensures accurate data recording even when processing multiple samples. Furthermore, the device utilizes an active interface and positioning head connected to a release switch, a departure from the common top-opening design of handheld detectors. This allows operators to easily monitor the detector's status. Failure to connect properly prevents the device from closing completely for detection, avoiding the problem of loose closure often found in top-opening detectors.

[0004] According to its publicly available technical solutions, existing near-infrared spectroscopy detection equipment has several drawbacks. First, when using conveyor belts to transport food, the belts are prone to loosening due to prolonged tension, leading to slippage and compromising the stability of food testing. Second, when using conveyor belts to transport food, bacteria can easily grow on the belts, jeopardizing the safety of the food production environment. Third, the detection equipment can generate heat during prolonged operation, which is detrimental to its operational safety. Summary of the Invention

[0005] This disclosure aims to at least partially address one of the technical problems in the related art.

[0006] Therefore, the purpose of this disclosure is to provide a multi-dimensional environmental testing device for extending the shelf life of food.

[0007] To achieve the above objectives, this disclosure provides a multi-dimensional environmental testing device for extending the shelf life of food, comprising: an anti-mixing conveyor component, which includes a conveyor belt and partitions; a shelf-extending component installed on the top of the conveyor belt, which includes a shielding box, a rotating light shield, and an optical detector; the conveyor belt drives the partitions to push the bottom of the rotating light shield, which adheres to the partitions under the frictional resistance of the shielding box; the bottom of the rotating light shield is in close contact with at least two partitions, blocking light from entering the shielding box; and a purification detection component installed at the bottom of the conveyor belt, which includes a cleaning box and a disinfection box. The system includes a disinfection detection box and an isolation plate. The isolation plate is attached to one side of the disinfection detection box and blocks airflow from flowing outward from one side of the box. A deflection assembly is installed on the conveyor belt, which includes a pull roller and a winding roller. The bottom of the conveyor belt bypasses the winding roller and enters the cleaning box and the disinfection detection box respectively. The cleaning box and the disinfection detection box are tensioned by the pull roller. A slag blowing assembly is installed on the cleaning box, which includes a high-pressure blower, an upper blowing port, and a lower blowing port. The bottom of the conveyor belt bypasses the pull roller to increase the angle between the partition plate and the conveyor belt. The high-pressure blower blows high-pressure airflow through the upper blowing port and the lower blowing port to clean the conveyor belt and the partition plate at the increased angle.

[0008] Optionally, a support assembly is installed on the outer side of the conveyor belt. The support assembly includes a support frame and support legs. The support legs are welded to the bottom of the support frame. Self-aligning rollers are installed at both ends of the support frame via bearings. The conveyor belt is sleeved on the outer side of the two self-aligning rollers. A motor is installed on the outer side of one end of the support frame via bolts. One end of the self-aligning roller is keyed to the output shaft of the motor.

[0009] Optionally, the shielding box is bolted to the top of the support frame, and both ends of the shielding box have openings. The width of the openings is equal to the length of the partition plate. The optical detector is bolted to the inner wall of the top of the shielding box.

[0010] Optionally, a slide rail is welded to the bottom of the support frame, and sliders are bolted to the outer sides of both the cleaning box and the disinfection and detection box. The sliders are locked inside the slide rails. A base plate is welded to the bottom of the support leg, and the bottoms of both the cleaning box and the disinfection and detection box are connected to the top of the base plate by springs.

[0011] Optionally, the pull rollers are respectively installed inside the cleaning box and the disinfection and detection box via bearings, and the winding rollers are installed on both sides of the support frame via bearings. The winding rollers are symmetrically distributed on the top of the pull rollers, and the spacing between the symmetrically distributed winding rollers is equal to twice the sum of the radius of the pull roller and the thickness of the conveyor belt.

[0012] Optionally, one end of the blower is welded to one side of the cleaning box, and the other end of the blower extends to the inside of the cleaning box. The upper and lower nozzles are welded to the top and bottom of the other end of the blower, respectively, and the high-pressure blower is installed inside the blower by bolts.

[0013] Optionally, a filter screen is bolted to the inner wall of the cleaning box, and an air supply duct is bolted to the bottom of the other side of the cleaning box. The other end of the air supply duct is bolted to the bottom of one side of the disinfection and testing box. The cleaning box is connected to the disinfection and testing box through the air supply duct, and a large fan is bolted to the inner side of the air supply duct.

[0014] Optionally, an infrared detector 1 and an infrared detector 2 are bolted to the inside of the disinfection and testing box. The infrared detector 2 is located on top of the infrared detector 1, and the top of the infrared detector 2 is located at the bottom of the conveyor belt that is pulled into the disinfection and testing box by the pull roller. An air pressure plate is bolted to one side of the infrared detector 1. One side of the air pressure plate is bolted to the inner wall of one side of the disinfection and testing box. One side of the air pressure plate is located at the top of the other end of the air supply duct. A return plate is bolted to the inner wall of the other side of the disinfection and testing box. One side of the return plate is sleeved on the outer side of the infrared detector 2.

[0015] Optionally, two ultraviolet lamps are bolted to the inside of the cleaning box, and two ultraviolet lamps are bolted to the inside of the disinfection and detection box. A focusing cover is fitted on the outside of both ultraviolet lamps, and the focal point of the focusing cover is located on the outer side of the conveyor belt.

[0016] Optionally, the isolation plate is bolted to the bottom of the support frame, and the top of the isolation plate is respectively attached to the bottom of the conveyor belt and the partition plate. The width of the inner side of the cleaning box and the disinfection and detection box is equal to the width of the conveyor belt.

[0017] The technical solution provided in this disclosure may include the following beneficial effects: In operation, the food to be tested is placed within the gaps of the partitions at the top of the conveyor belt. A motor drives a self-aligning roller on the outside of the support frame, which in turn moves the conveyor belt to the left on the inside of the support frame. This transports the food through the openings on the inside of the partitions to the inside of the shielding box. The conveyor belt, via the partitions, pushes the bottom of a rotating light shield to rotate. The rotating light shield maintains a tight seal with the partitions due to frictional resistance against the inner wall of the shielding box, ensuring that the bottom of the rotating light shield contacts at least two partitions. This effectively blocks light from entering the shielding box through the openings, allowing optical detectors to perform trace detection, micro-quantity detection, and micro-element analysis of the food using optical methods (such as submillimeter waves, infrared light, visible light, or ultraviolet light), thus completing the food transport process. As the conveyor belt moves to the right at the bottom of the support frame, the cleaning box and disinfection and testing box, along with their installed components, drive the pull rollers by gravity. The pull rollers pull the bottom of the conveyor belt downwards and support the bottom of the conveyor belt without partitions through the winding rollers. This effectively ensures the stability of the conveyor belt tension, preventing rapid deformation or damage due to excessive tension, and also preventing insufficient friction between the conveyor belt and the self-aligning rollers due to insufficient tension, thus preventing the conveyor belt from slipping. This effectively ensures the stable transport of food by the conveyor belt, thereby ensuring the stability of food and food environment testing. The cleaning box and disinfection and testing box slide on the inside of the slide rail via sliders to prevent skewing, and are maintained stable by springs and a base plate.

[0018] During operation, a high-pressure blower blows air through the blower into the inner sides of the upper and lower nozzles. The strong airflow is then directed towards the conveyor belt and separators. As the conveyor belt and separators pass over the bottom of the pull rollers, the angle between them increases. This reduces or eliminates the adhesion and clamping forces on dust, food residue, and other impurities in the gaps between the conveyor belt and separators, allowing for easy removal and improving cleanliness. Ultraviolet lamps then disinfect and sterilize the cleaned conveyor belt and separators. A concentrator focuses the ultraviolet light generated by the lamps onto the surfaces of the conveyor belt and separators. Utilizing the increased angle between the conveyor belt and separators at the pull rollers, the system effectively disinfects the area within this angle, enhancing the cleaning and disinfection process and preventing bacterial growth on the conveyor belt and separators, thus ensuring a safe food testing environment.

[0019] During operation, the large fan generates suction in the cleaning box via the air duct, drawing out and filtering the cleaned debris onto the top of the filter screen. This prevents impurities from contaminating the environment and affecting the focusing effect of the light-gathering hood. The large fan delivers airflow to the inside of the disinfection and testing box, where it is guided by the air compressor to the bottom of infrared detector one. Infrared detector one then detects the airflow. The airflow then flows to the left from the bottom of the return plate, and the top left side of the disinfection and testing box is blocked by an isolation plate. The air then flows to the right through the top of infrared detector two and exits through the top right side of the disinfection and testing box. As the airflow exits, ultraviolet lamp two, under the action of the light-gathering hood, disinfects the air and the conveyor belt, thereby improving food safety and simultaneously enhancing the cleaning process. The airflow generated during air detection effectively cools ultraviolet lamp 1, ultraviolet lamp 2, infrared detector 1, and infrared detector 2. This ensures equipment safety while maximizing airflow and saving energy. As the conveyor belt moves the partition plate outside the focusing hood, it continuously pours air into different locations within the hood, effectively cooling ultraviolet lamps 1 and 2. The partition plate guides the airflow to improve cooling efficiency and prevents air from flowing to the left at the top of the disinfection and detection chamber. Instead, it directs airflow from left to right at the bottom of the conveyor belt, expanding the scope of air detection and sterilization.

[0022] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, this disclosure proposes a multi-dimensional environmental detection device for extending the shelf life of food, comprising: an anti-mixing conveyor component, which includes a conveyor belt 9 and a partition plate 10; a shelf-extending component installed on the top of the conveyor belt 9, which includes a shielding box 3, a rotating light shield 5, and an optical detector 6; the conveyor belt 9 drives the partition plate 10 to push the bottom of the rotating light shield 5; the rotating light shield 5 adheres tightly to the partition plate 10 under the frictional resistance of the shielding box 3; the bottom of the rotating light shield 5 is in close contact with at least two partition plates 10 to block light from entering the shielding box 3; a purification detection component installed at the bottom of the conveyor belt 9, which includes a cleaning box 11, a disinfection detection box 12, and a partition plate 31; the partition plate 31 adheres tightly to one side of the disinfection detection box 12 and blocks airflow from flowing outward from one side of the disinfection detection box 12; a reversing component installed on the conveyor belt 9, which includes a pull roller 13 and a winding roller 14; and the conveyor belt... The bottom of conveyor belt 9 passes around roller 14 and enters cleaning box 11 and disinfection and detection box 12 respectively. Cleaning box 11 and disinfection and detection box 12 tension conveyor belt 9 through pull roller 13. Cleaning box 11 is equipped with a slag blowing assembly, which includes a high-pressure blower 16, an upper blowing port 17 and a lower blowing port 18. The bottom of conveyor belt 9 passes around pull roller 13 to increase the angle between the partition plate 10 and conveyor belt 9. High-pressure blower 16 blows high-pressure air through upper blowing port 17 and lower blowing port 18 to clean the increased angle of conveyor belt 9 and partition plate 10. A support assembly is installed on the outside of conveyor belt 9. The support assembly includes support frame 1 and support leg 2. Support leg 2 is welded to the bottom of support frame 1. Self-aligning rollers 8 are installed at both ends of support frame 1 through bearings. Conveyor belt 9 is sleeved on the outer side of the two self-aligning rollers 8. Motor 7 is installed on the outer side of one end of support frame 1 through bolts. One end of self-aligning roller 8 is keyed to the output shaft of motor 7.

[0024] Understandably, during use, the high-pressure blower 16 blows air through the blower 15 into the inner sides of the upper nozzle 17 and the lower nozzle 18, respectively. The strong airflow is then directed towards the conveyor belt 9 and the partition plate 10 through the upper nozzle 17 and the lower nozzle 18. As the conveyor belt 9 and the partition plate 10 pass over the bottom of the pull roller 13, the angle between them increases. This reduces or eliminates the adhesion and clamping forces on dust, food residue, and other impurities in the gap between the conveyor belt 9 and the partition plate 10, allowing for easy removal of these impurities and improving the efficiency of the connection between the conveyor belt 9 and the partition plate 10. The cleanliness of the conveyor belt 9 and the partition plate 10 is achieved by using ultraviolet lamp 19 to disinfect and sterilize them. The ultraviolet light generated by the ultraviolet lamp 19 is focused onto the surface of the conveyor belt 9 and the partition plate 10 by the concentrator 30. Taking advantage of the fact that the angle between the conveyor belt 9 and the partition plate 10 increases at the pull roller 13, the area within the angle between the conveyor belt 9 and the partition plate 10 can be effectively disinfected. This can effectively improve the cleaning and disinfection effect of the conveyor belt 9, prevent bacterial growth on the conveyor belt 9 and the partition plate 10, and ensure the safety of the food testing environment.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, a filter screen 20 is bolted to the inner wall of the cleaning box 11. An air supply duct 23 is bolted to the bottom of the other side of the cleaning box 11. One end of the air supply duct 23 is bolted to the bottom of one side of the disinfection and testing box 12. The cleaning box 11 is connected to the disinfection and testing box 12 through the air supply duct 23. A large fan 24 is bolted to the inner side of the air supply duct 23. An infrared detector 1 25 and an infrared detector 26 are bolted to the inner side of the disinfection and testing box 12. The infrared detector 26 is located on top of the infrared detector 1 25. The top of the infrared detector 26 is located at the bottom of the conveyor belt 9 that is pulled into the disinfection and testing box 12 by the pull roller 13. A pressure plate 27 is bolted to one side of the infrared detector 1 25. One side of the pressure plate 27 is bolted to the disinfection and testing box 12. On one side of the inner wall of the box 12, one side of the air pressure plate 27 is located at the top of one end of the air supply duct 23. On the other side of the inner wall of the disinfection and detection box 12, a return plate 28 is installed by bolts. One side of the return plate 28 is sleeved on the outer side of the infrared detector 26. Two ultraviolet lamps 19 are installed on the inner side of the cleaning box 11 by bolts. Two ultraviolet lamps 29 are installed on the inner side of the disinfection and detection box 12 by bolts. A focusing cover 30 is sleeved on the outer side of both ultraviolet lamps 19 and 29. The focal point of the focusing cover 30 is located on the outer side of the conveyor belt 9. The isolation plate 31 is installed on the bottom of the support frame 1 by bolts. The top of the isolation plate 31 is respectively attached to the bottom of the conveyor belt 9 and the partition plate 10. The width of the inner side of the cleaning box 11 and the disinfection and detection box 12 is equal to the width of the conveyor belt 9.

[0026] Understandably, during use, the large fan 24 generates suction on the cleaning box 11 through the air supply duct 23, drawing the cleaned debris downwards and filtering it onto the top of the filter screen 20, preventing impurities from polluting the environment and affecting the focusing effect of the focusing hood 30. The large fan 24 delivers airflow to the inside of the disinfection and testing box 12, where the airflow is guided by the air compressor 27 to the bottom of the infrared detector 25. The infrared detector 25 then detects the air. The airflow then flows to the left from the bottom of the return plate 28, and the isolation plate 31 blocks the top left side of the disinfection and testing box 12, causing the air to flow to the right through the top of the infrared detector 26 and out through the top right side of the disinfection and testing box 12. As the airflow flows out, the ultraviolet lamp 29, under the action of the focusing hood 30, disinfects the air and the conveyor belt 9, thereby improving the safety of the food environment. During cleaning and air detection, the airflow generated effectively cools the UV lamp 19, UV lamp 29, infrared detector 15, and infrared detector 26, ensuring equipment safety and maximizing airflow efficiency while saving energy. As the conveyor belt 9 moves the partition plate 10 outside the focusing cover 30, it continuously pours air into different locations within the focusing cover 30, effectively cooling the UV lamp 19 and UV lamp 29. The partition plate 31 guides the airflow to improve the cooling effect on the UV lamp 19 and UV lamp 29 and prevents air from flowing to the left at the top of the disinfection and detection box 12, ensuring a left-to-right airflow at the bottom of the conveyor belt 9, thus expanding the scope of air detection and sterilization.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the shielding box 3 is bolted to the top of the support frame 1. Both ends of the shielding box 3 have openings 4, the width of which is equal to the length of the partition plate 10. The optical detector 6 is bolted to the inner wall of the top of the shielding box 3. A slide rail 32 is welded to the bottom of the support frame 1. Slider blocks 33 are bolted to the outer sides of both the cleaning box 11 and the disinfection detection box 12, and these sliders 33 are engaged with the inner side of the slide rail 32. A base plate 21 is welded to the bottom of the support leg 2. The bottoms of both the cleaning box 11 and the disinfection detection box 12 are connected to the top of the base plate 21 by springs 22. Rollers 13 are mounted on the inner sides of the cleaning box 11 and the disinfection and detection box 12 respectively via bearings. The winding rollers 14 are mounted on both sides of the support frame 1 via bearings. The winding rollers 14 are symmetrically distributed on the top of the pull rollers 13. The spacing between the symmetrically distributed winding rollers 14 is equal to twice the sum of the radius of the pull rollers 13 and the thickness of the conveyor belt 9. One end of the blower 15 is welded to one side of the cleaning box 11, and the other end of the blower 15 extends to the inner side of the cleaning box 11. The upper blow port 17 and the lower blow port 18 are welded to the top and bottom of the other end of the blower 15 respectively. The high-pressure blower 16 is mounted on the inner side of the blower 15 by bolts.

[0028] Understandably, during use, the food to be tested is placed within the intervals of the partition plates 10 located at the top of the conveyor belt 9. The motor 7 drives the self-aligning roller 8 on the outside of the support frame 1. The self-aligning roller 8 drives the conveyor belt 9 to move to the left on the inside of the support frame 1, thereby conveying the food through the opening 4 on the inside of the partition plates 10 to the inside of the shielding box 3. The conveyor belt 9 pushes the bottom of the rotating light shield 5 to rotate through the partition plates 10. The rotating light shield 5 remains in close contact with the partition plates 10 due to the frictional resistance with the inner wall of the shielding box 3, ensuring that the bottom of the rotating light shield 5 contacts at least two partition plates 10. This effectively blocks light from entering the inside of the shielding box 3 through the opening 4, so that the optical detector 6 can perform trace detection, micro-detection, and micro-element analysis of the food using optical means (such as submillimeter wave, infrared light, visible light, or ultraviolet light), thus completing the food transport process. When the conveyor belt 9 moves to the right at the bottom of the support frame 1, the cleaning box 11 and the disinfection and testing box 12 and their installed components drive the pull roller 13 by gravity. The pull roller 13 pulls the bottom of the conveyor belt 9 downward and supports the bottom of the conveyor belt 9 without the partition plate 10 through the winding roller 14. This can effectively ensure the stability of the tension of the conveyor belt 9, which can prevent the conveyor belt 9 from being deformed or damaged quickly due to excessive tension, and can also prevent the conveyor belt 9 from having insufficient friction with the self-correcting roller 8 due to insufficient tension, thus preventing the conveyor belt 9 from slipping. This effectively ensures that the conveyor belt 9 can stably transport food, and thus ensures the stability of food and food environment testing. The cleaning box 11 and the disinfection and testing box 12 slide on the inside of the slide rail 32 through the slider 33 to avoid deflection. The cleaning box 11 and the disinfection and testing box 12 are kept stable by the spring 22 and the base plate 21.
