Description

[0001] This application is a divisional application of application filed on October 9, 2025, with application number 2025114345617 and invention title "A Rheological Property Detector for Food Standardization". Technical Field

[0002] This invention belongs to the field of food rheology testing technology, and specifically relates to a standardized rheological property testing instrument for food. Background Technology

[0003] The testing of the rheological properties of food is of great significance for food standardization. By analyzing the flow and deformation behavior of food under external forces (such as parameters such as viscosity and elastic modulus), processing conditions (such as conveying speed and stirring intensity) can be precisely adjusted to ensure efficient and stable production processes and reduce product defects.

[0004] A search revealed that Chinese Patent Publication No. CN222318728U, published on January 7, 2025, discloses an online rheometer, including a fixed frame. The rheometer body is located outside the fixed frame, and a detection mechanism is located inside the rheometer body. The detection mechanism includes a rotating blade for stirring the solution to be tested, and a detection component connected to the rotating blade. The detection component is used to detect the rheological properties of the solution to be tested through the rotating blade. This invention, through its innovative detection mechanism and sealed separation design, effectively avoids the problems of the solution to be tested entering the detection component, affecting the accuracy of the test and causing cleaning difficulties, which are common with traditional shaft connections. Furthermore, the magnetic attraction not only facilitates the quick disassembly or installation of components such as the rotating blade, but also allows the resistance force generated by the rotation of the rotating blade in the solution to be detected by the detection component.

[0016] The beneficial effects of this invention are: 1. By controlling the rotation of the second rotating disk according to the shape of the food sample, after adjusting to the corresponding rotor, the detection motor is controlled to drive the first connecting component to descend and complete the connection with the second connecting component, and continue to descend, so that the rotor at the bottom of the connecting column contacts the food sample.

[0018] 3. By controlling two sets of rotary motors to rotate upwards, the two sets of rotary motors will drive two sets of splash guards to rotate. When the two sets of rotary motors rotate to the vertical line, the two sets of splash guards will complete the splicing work on the side of the rotor near the second rotating disk. Then, control two sets of rotating rods to drive two sets of rotating nozzles to rotate to both sides of the rotor. Then, control the rotating nozzles to spray cleaning liquid towards the rotor and control the two sets of cleaning rollers to rotate to clean the rotor. After the cleaning work is completed, the two sets of rotating nozzles can also spray hot air to dry the rotor.

[0019] 4. By controlling the rotation of two sets of lead screws, and through the threaded connection between the two sets of lead screws and the two sets of sliders, the two sets of translation plates drive the two sets of limit blocks to disengage from the rotor switching mechanism. This allows the rotor switching mechanism to be quickly removed from the rotor cleaning mechanism. Furthermore, since the rotor switching mechanism can move vertically between the two sets of translation plates via the two sets of limit blocks, the height of the rotor switching mechanism can be adjusted by controlling the electric push rod to raise and lower the rotor cleaning mechanism. This improves both the maintenance efficiency and ease of use of the rheological property tester.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] This invention provides a standardized rheological property testing instrument for food, including a testing platform 1. For example, as shown... Figure 1 , Figure 2 and Figure 3 As shown, two sets of electric sliding stages 2 are symmetrically arranged on the top two sides of the detection platform 1; a detection motor 3 is driven to the output end of the two sets of electric sliding stages 2; a first connecting component 4 is driven to the output end of the detection motor 3; a movable groove 5 is opened on the top of the detection platform 1; a sample placement mechanism 6 is provided in the movable groove 5; two sets of lifting guide rails 7 are symmetrically opened on the inner walls of both sides of the movable groove 5; a set of limiting plates 8 are driven to the output end of each set of lifting guide rails 7; a rotor switching mechanism 9 is provided above the detection platform 1; two sets of first sliding grooves 10 are symmetrically opened on the top two sides of the detection platform 1; a set of translation plates 11 is provided in each set of first sliding grooves 10; a set of limiting blocks 12 are respectively damped and slidably connected to the opposite side wall of the two sets of translation plates 11. The detection platform 1 has several sets of electric push rods 13 on one side wall away from the movable groove 5; the output ends of the sets of electric push rods 13 are connected to a rotor cleaning mechanism 14; the rotor switching mechanism 9 is movably inserted through the rotor cleaning mechanism 14; the detection platform 1 has an adjustment cavity 15; the adjustment cavity 15 is connected to both sets of first sliding grooves 10; the adjustment cavity 15 has two sets of lead screws 16; one end of the two sets of lead screws 16 is fixedly connected, and the other end is rotatably connected to the inner walls on both sides of the adjustment cavity 15; the thread directions of the two sets of lead screws 16 are opposite, and their central axes are on the same straight line; two sets of sliders 17 are slidably connected to the bottom inner wall of the adjustment cavity 15; each set of sliders 17 is threadedly connected to a corresponding set of lead screws 16 and is connected to a corresponding set of translation plates 11.

[0026] When conducting rheological property testing of food, the food sample is first placed in the sample placement mechanism 6. Then, the rotor switching mechanism 9 is controlled to switch to the corresponding rotor structure according to the shape of the food. Then, the two sets of electric slides 2 are controlled to drive the detection motor 3 to descend. The first connecting component 4 on the output end of the detection motor 3 is connected to the corresponding rotor structure for transmission. Then, the corresponding rotor structure is driven to either contact or penetrate into the food sample. The detection motor 3 is then controlled to drive the rotor structure to rotate. By monitoring the rotational torque of the rotor structure and the changes in the shape of the food, the rheological properties of the food are detected. By controlling the rotation of two sets of lead screws 16, and through the threaded connection between the two sets of lead screws 16 and the two sets of sliders 17, the two sets of translation plates 11 drive the two sets of limit blocks 12 to disengage from the rotor switching mechanism 9. This allows the rotor switching mechanism 9 to be quickly removed from the rotor cleaning mechanism 14. Furthermore, since the rotor switching mechanism 9 can move vertically between the two sets of translation plates 11 via the two sets of limit blocks 12, the height of the rotor switching mechanism 9 can be adjusted by controlling the electric push rod 13 to raise and lower the rotor cleaning mechanism 14. This improves both the maintenance efficiency and ease of use of the rheological property tester.

[0027] For example, such as Figure 4 and Figure 5 As shown, the sample placement mechanism 6 includes a first rotating disk 601; an adjusting column 602 is provided on the top of the first rotating disk 601; a first limiting groove 603 is provided on the outer wall of the adjusting column 602; each set of limiting plates 8 is slidably connected in the first limiting groove 603; a plurality of placement slots 604 are arranged in a circular array on the top of the adjusting column 602; a plurality of placement columns 605 are arranged in a circular array on the top of the first rotating disk 601; each set of placement columns 605... Each of the following is provided with a set of placement grooves 606 at the top; a set of sealing rings 607 is provided at the top edge of each set of placement columns 605; a set of heat-conducting grooves 608 is provided on the inner wall of each set of placement channels 604; a set of heat-conducting rings 609 is provided in each set of heat-conducting grooves 608; each set of placement columns 605 is movably inserted into the corresponding set of placement channels 604 and heat-conducting rings 609; and several sets of heating plates 610 are arranged in a ring array on the inner wall of each set of heat-conducting grooves 608.

[0028] When conducting rheological property testing on food, different food samples are placed in the placement grooves 606 on top of the placement columns 605 within the corresponding placement channels 604. Since two sets of liftable limiting plates 8 are slidably connected within the first limiting groove 603, the first rotating disk 601 can transfer different food samples to the area below the rotor switching mechanism 9 for testing when it rotates. Furthermore, the two sets of limiting plates 8 can adjust the placement volume of the food samples by driving the adjusting column 602 to raise or lower. This allows the rheological property tester to complete the rheological property testing of food samples of different shapes or quantities in a single operation, thereby improving the testing efficiency of the rheological property tester.

[0029] For example, such as Figure 6 and Figure 7 As shown, the rotor switching mechanism 9 includes a protective housing 901; two sets of second limiting grooves 902 are symmetrically opened on the outer wall of the protective housing 901; each set of limiting blocks 12 is movably inserted into the corresponding set of second limiting grooves 902; a detection groove 903 and a cleaning groove 904 are opened on the protective housing 901; the detection groove 903 is located above the sample placement mechanism 6, and the cleaning groove 904 is located inside the rotor cleaning mechanism 14; a movable sealing cover 905 is provided on the outer wall of the protective housing 901; a rotating shaft 906 is provided inside the protective housing 901; a second rotating disk 907 is sleeved on the outer wall of the rotating shaft 906; several sets of lifting grooves 908 are arranged in a circular array on the side wall of the second rotating disk 907; two sets of second limiting grooves 908 are symmetrically opened on the inner walls of both sides of each set of lifting grooves 908. Two sliding grooves 909; each set of lifting channels 908 is provided with a set of lifting plates 911; both ends of each set of lifting plates 911 are slidably connected to a corresponding set of second sliding grooves 909; each set of second sliding grooves 909 is provided with a set of return springs 910 on the bottom inner wall; the top of each set of return springs 910 is connected to a corresponding set of lifting plates 911; each set of lifting plates 911 is provided with a set of bearings 912 at the top center; each set of bearings 912 is provided with a set of connecting columns 913; the bottom of each set of connecting columns 913 extends to the bottom of the lifting plates 911 and is connected to a set of rotors 914; the top of each set of connecting columns 913 extends to the top of the lifting plates 911 and is connected to a set of second connecting components 915; the second connecting components 915 are movably connected to the first connecting components 4.

[0030] When performing rheological property testing on food, the movable sealing cover 905 is rotated to expose the detection channel 903. After adjusting the rotor 914 according to the shape of the food sample, the detection motor 3 drives the first connecting component 4 to descend and connect with the second connecting component 915. Then, the detection motor 3 continues to descend so that the rotor 914 at the bottom of the connecting column 913 contacts the food sample to perform rheological property testing. This avoids the need to frequently change different types of rotors 914 when performing rheological property testing on different types of food. After the testing is completed, the rotor 914 can automatically reset when the detection motor 3 is reset. Then, the movable sealing cover 905 closes the detection channel 903, preventing multiple sets of rotors 914 from being damaged by external forces and from prolonged exposure to air. This improves the performance and service life of the rheological property tester.

[0031] The second connecting component 915 includes a connecting ring 9151; the top of the connecting ring 9151 is provided with a plurality of connecting slots 9152 arranged in a ring array; the outer wall of the connecting ring 9151 is provided with positioning magnetic blocks 9153 in a ring array, the same number as the connecting slots 9152.

[0032] The structure of the first connecting component 4 is similar to that of the second connecting component 915, but several sets of positioning magnetic blocks 9153 correspond to the connecting groove 9152 and the protrusion respectively. When the first connecting component 4 approaches the second connecting component 915, the protrusion of the first connecting component 4 is magnetically attracted to the connecting groove 9152 of the second connecting component 915, thereby quickly completing the docking work and facilitating the subsequent rotation of the rotor 914.

[0033] For example, such as Figure 8 and Figure 9As shown, the rotor cleaning mechanism 14 includes a housing 1401; a cleaning chamber 1402 is provided inside the housing 1401; a dirt collection trough 1403 is provided on the bottom inner wall of the cleaning chamber 1402; two sets of rotary motors 1404 are symmetrically arranged on the inner wall of the dirt collection trough 1403 near the rotor switching mechanism 9; a set of splash guards 1405 is drivenly connected to the output end of each set of rotary motors 1404; the two sets of splash guards 1405 can be rotatably spliced ​​into a semi-circular ring structure; each set of A set of cleaning rollers 1406 is provided on one inner wall of the splash guard 1405; two sets of rotating rods 1407 are symmetrically provided on the inner wall of the cleaning chamber 1402 away from the rotor switching mechanism 9; a set of rotating nozzles 1408 is provided at the bottom of the end of each set of rotating rods 1407 away from the rotating shaft; a liquid storage box 1409 and a hot air gun 1410 are provided on the top inner wall of the cleaning chamber 1402; the output ends of the liquid storage box 1409 and the hot air gun 1410 are connected to the two sets of rotating nozzles 1408.

[0034] After the rheological properties testing of the food is completed, the two sets of rotary motors 1404 are controlled to rotate upwards. At the same time, the two sets of rotary motors 1404 drive the two sets of anti-splash baffles 1405 to rotate. When the two sets of rotary motors 1404 rotate to the vertical line, the two sets of anti-splash baffles 1405 complete the splicing work on the side of the rotor 914 near the second rotating disk 907. Then, the two sets of rotating rods 1407 are controlled to drive the two sets of rotating nozzles 1408 to rotate to both sides of the rotor 914. Then, the rotating nozzles 1408 are controlled to spray cleaning liquid towards the rotor 914 and the two sets of cleaning rollers 1406 are controlled to rotate to clean the rotor 914. After the cleaning work is completed, the two sets of rotating nozzles 1408 can also spray hot air to dry the rotor 914. This improves the cleaning effect of the rheological property tester and avoids splash pollution of waste liquid.

[0035] By controlling the rotation of the second rotating disk 907 according to the shape of the food sample, after adjusting to the corresponding rotor 914, the detection motor 3 drives the first connecting component 4 to descend and connect with the second connecting component 915, and continues to descend, so that the rotor 914 at the bottom of the connecting column 913 comes into contact with the food sample. This avoids the need to frequently change different types of rotors 914 when performing rheological property testing on foods of different shapes. After the testing is completed, the rotor 914 can automatically reset. Then, the movable sealing cover 905 is controlled to seal the detection channel 903, preventing multiple sets of rotors 914 from being damaged by external forces and from being exposed to air for a long time. This improves the performance of the rheological property tester and extends its service life.

[0036] By placing different food samples into the placement grooves 606 on top of the placement columns 605 in the corresponding placement slots 604, and with two sets of liftable limiting plates 8 slidably connected in the first limiting groove 603, the first rotating disk 601 can transfer different food samples to the area below the rotor switching mechanism 9 for testing when it rotates. Furthermore, the two sets of limiting plates 8 can adjust the placement volume of the food samples by driving the adjusting column 602 to raise or lower, enabling the rheological property analyzer to complete the rheological property testing of food samples of different shapes or quantities in a single operation, thereby improving the testing efficiency of the rheological property analyzer.

[0037] By controlling two sets of rotary motors 1404 to rotate upwards, the two sets of rotary motors 1404 will drive two sets of splash guards 1405 to rotate. When the two sets of rotary motors 1404 rotate to the vertical line, the two sets of splash guards 1405 complete the splicing work on the side of rotor 914 near the second rotating disk 907. Then, control the two sets of rotating rods 1407 to drive the two sets of rotating nozzles 1408 to rotate to both sides of rotor 914. Then, control the rotating nozzles 1408 to spray cleaning liquid towards rotor 914 and control the two sets of cleaning rollers 1406 to rotate to clean rotor 914. After the cleaning work is completed, the two sets of rotating nozzles 1408 can also spray hot air to dry rotor 914. This improves the cleaning effect of rheological property tester and avoids splash pollution of waste liquid.

[0038] By controlling the rotation of two sets of lead screws 16, and through the threaded connection between the two sets of lead screws 16 and the two sets of sliders 17, the two sets of translation plates 11 drive the two sets of limit blocks 12 to disengage from the rotor switching mechanism 9. This allows the rotor switching mechanism 9 to be quickly removed from the rotor cleaning mechanism 14. Furthermore, since the rotor switching mechanism 9 can move vertically between the two sets of translation plates 11 via the two sets of limit blocks 12, the height of the rotor switching mechanism 9 can be adjusted by controlling the electric push rod 13 to raise and lower the rotor cleaning mechanism 14. This improves both the maintenance efficiency and ease of use of the rheological property tester.
