Description

Technical Field

[0001] This invention relates to the field of testing the dissolution rate of nutritional rice cereal, and more particularly to a device for testing the dissolution rate of nutritional rice cereal for children. Background Technology

[0002] Nutritional rice cereal provides essential nutrients for infants' growth and is a scientifically prepared complementary food. Its preparation involves mixing high-quality rice and other grains with nutrients. When feeding infants nutritional rice cereal, it needs to be prepared by mixing it with water. The dissolution rate of the nutritional rice cereal varies with different water volumes, necessitating testing to determine the optimal preparation standard. Current methods for testing the dissolution rate typically involve placing the nutritional rice cereal in a dissolving container and then adjusting the water volume and dissolution temperature under conditions of the same water volume and different temperatures, or the same temperature and different water volumes. During the test, the stirring required for dissolution causes the container to shake, leading to uneven heating and introducing two variables that affect the accuracy of the test.

[0003] Therefore, we are now developing a device for testing the dissolution rate of children's nutritional rice cereal that can stably limit the position of the dissolution container during the temperature control process. Summary of the Invention

[0004] To overcome the shortcomings of existing devices that require stirring during dissolution, which causes the dissolution container to shake, resulting in uneven heating and two variables that affect the accuracy of the test, this invention provides a dissolution rate testing device for children's nutritional rice cereal that can stably limit the position of the dissolution container during temperature control.

[0005] The technical solution of the present invention is as follows: a dissolution rate testing device for children's edible nutritional rice cereal, comprising a mounting plate, placement components, guide plates, stirring components, detection probes, a water injection mechanism, and a temperature control mechanism. Multiple placement components are triangularly distributed on the mounting plate. Multiple guide plates are evenly connected to the top of the mounting plate. Stirring components are slidably connected to each guide plate. Detection probes for detecting the dissolution rate are connected to the bottom of each stirring component. A water injection mechanism for controlling the amount of dissolved water is provided on the mounting plate. A temperature control mechanism for adjusting the dissolution test temperature is provided on each guide plate.

[0006] Furthermore, it is particularly preferred that the water injection mechanism includes a water storage tank, a water pump, a water suction pipe, a water outlet pipe, and a control valve. The water storage tank is connected to the center of the top of the mounting plate, and three water pumps for discharging clean water are connected to the top of the water storage tank. A water suction pipe is connected between each water pump and the water storage tank. A water outlet pipe for discharging clean water is connected to the side of each water pump that is close to each other, and a control valve for controlling the water flow is rotatably connected to the side of each water outlet pipe that is far apart from each other.

[0007] Furthermore, it is particularly preferred that the temperature control mechanism includes a fixed base, a rotating plate, a heating tube, and an outer frame. The fixed base is connected to the side of the guide plate that is far apart from each other. The two rotating plates for limiting the position of the dissolving container are rotatably connected to the side of the fixed base that is far apart from each other. The heating tube for heating and controlling the temperature of the dissolving container is connected to the side of the rotating plates that is close to each other. The outer frame for preventing burns is connected to the side of the rotating plates that is far apart from each other.

[0008] In addition, it is particularly preferred that the assembly also includes a splash-proof mechanism, which includes a spring, a top cover and a rubber layer. The upper part of the stirring assembly is connected to a spring, and the bottom of the spring is connected to a top cover for covering and sealing the dissolving container. The bottom of the top cover is connected to a rubber layer for enhancing the sealing effect.

[0009] Furthermore, preferably, it also includes an opening and closing mechanism, which includes a first connecting rod, a guide frame, a support rod, an elastic rope, a guide rod, a sliding frame, a locking rod, and a torsion spring. Two symmetrically distributed support rods are connected to the upper outer side of each mounting plate. The top of each support rod is connected to a guide frame when rotating. A torsion spring is connected between each guide frame and an adjacent support rod, and the torsion spring is wound around the adjacent support rod. A first connecting rod is connected to the bottom of each rotating plate. The first connecting rod is slidably connected to an adjacent guide frame, and the guide frame can guide the movement of the adjacent first connecting rod. Two guide rods are connected to the sides of each guide plate that are close to each other. A sliding frame is slidably connected between adjacent guide rods. An elastic rope is connected between each guide frame and an adjacent sliding frame. Movement of the sliding frame will cause the elastic rope to pull the guide frame to rotate. Two locking rods are connected to the sides of each stirring assembly that are close to each other. The locking rods are slidably connected to an adjacent sliding frame, and the sliding frame can guide the adjacent locking rods.

[0010] In addition, it is particularly preferred that the assembly also includes a wall scraping mechanism, which includes a second connecting rod, a scraper and floats. The second connecting rod is slidably connected to the stirring assembly. Both ends of the second connecting rod are connected to scrapers for scraping the nutrient rice flour floating on the water surface. Two floats are connected to the second connecting rod for assisting in lifting.

[0011] Furthermore, it is particularly preferred that the guide plate also includes a stabilizing mechanism, which includes a connecting frame and a limiting plate. The connecting frame is connected to the side of the guide plate that is far apart from each other, and the limiting plate for limiting the dissolving container is connected to the side of the connecting frame that is far apart from each other.

[0012] Furthermore, it is particularly preferred that the placement assembly includes a support frame, a buffer, and a placement tray, with multiple support frames connected to the bottom of the mounting plate, buffers connected to the support frames, and placement trays connected to the top of the buffers.

[0013] Furthermore, it is particularly preferred that the mixing assembly includes a mixing mounting bracket, a mixing motor, and a mixing rack, with the mounting bracket slidably connected to the guide plate, the mixing motor connected to the mounting bracket, and the mixing rack connected to the output shaft of the mixing motor.

[0014] In addition, it is particularly preferred that the limiting plates are all arc-shaped structures, which can fit the melting container for limiting.

[0015] Compared with the prior art, the present invention has the following advantages: 1. The present invention clamps and fixes the dissolving container by the cooperation between the rotating plates, so as to avoid the dissolving container shaking and uneven heating. At the same time, it can assist the testers to quickly test the dissolution rate of the nutritional rice flour under the same water volume or under the same temperature at different temperature conditions or different water volumes.

[0016] 2. The present invention uses a stirring component to drive the upper cover to move, so that the upper cover fits into the dissolving container and covers and seals the top of the dissolving container, preventing the rice flour from splashing during the stirring process and causing differences in the original quantity of the test subject.

[0017] 3. In this invention, the movement of the stirring component causes the lever to slide along the corresponding sliding frame. At this time, the elastic rope will pull the corresponding guide frame to rotate, so that the rotating plate can open and close automatically, avoiding direct contact between the test personnel and the rotating plate, thus preventing unnecessary damage.

[0018] 4. In this invention, a float ball drives the second connecting rod to float on the water surface. Then, the stirring assembly drives the second connecting rod to rotate, so that the scraper scrapes the nutrient rice powder floating on the water surface, allowing the nutrient rice powder to be fully mixed and dissolved.

[0028] Although the invention may be described with respect to specific applications or industries, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0029] A device for testing the dissolution rate of children's nutritional rice cereal, such as... Figure 1 and Figure 2As shown, the assembly includes a mounting plate 1, placement components 2, guide plates 3, stirring components 4, detection probes 41, a water injection mechanism 5, and a temperature control mechanism 6. Three placement components 2 are arranged in a triangular pattern on the mounting plate 1. Each placement component 2 includes a support frame, a buffer, and a placement tray. Three support frames are bolted to the bottom of each mounting plate 1, and buffers are connected to each support frame. A placement tray is connected to the top of each buffer. Three guide plates 3 are evenly bolted to the top of the mounting plate 1. Stirring components 4 are slidably connected to each guide plate 3. Each stirring component 4 includes a stirring mounting frame, a stirring motor, and a stirring rack. A mounting frame is slidably connected to each guide plate 3, and a stirring motor is connected to each mounting frame. A stirring rack is connected to the output shaft of each stirring motor. Detection probes 41 are connected to the bottom of each stirring component 4. The mounting plate 1 is equipped with a water injection mechanism 5, and the guide plates 3 are equipped with a temperature control mechanism 6.

[0030] It should be noted that when conducting the dissolution rate test of children's nutritional rice cereal, multiple tests need to be performed depending on the temperature and water volume. First, pull the stirring component 4 upwards. Then, place the dissolving container on the placement component 2. Next, slide the stirring component 4 downwards to reset it, allowing the detection probe 41 to enter the dissolving container. Then, inject water to different heights into the three dissolving containers through the water injection mechanism 5, and use the temperature control mechanism 6 to keep the three dissolving containers at the same temperature for dissolution. Then, start the stirring component 4 to stir and dissolve the nutritional rice cereal. The detection probe 41 detects the dissolution rate of the nutritional rice cereal, testing the dissolution rate under the influence of different water volumes. After the test, repeat the above operation of placing the dissolving containers, injecting water to the same height into the three dissolving containers through the water injection mechanism 5, and controlling the temperature control mechanism 6 to keep the three dissolving containers at different temperatures for dissolution of the nutritional rice cereal, testing the dissolution rate of the nutritional rice cereal at different temperatures.

[0031] like Figure 1 and Figure 3 As shown, the water injection mechanism 5 includes a water storage tank 51, a water pump 52, a water suction pipe 53, a water outlet pipe 54, and a control valve 55. The water storage tank 51 is connected to the center of the top of the mounting plate 1. Three water pumps 52 are connected to the top of the water storage tank 51. Each water pump 52 is connected to the water storage tank 51 by a water suction pipe 53. Each water pump 52 is connected to a water outlet pipe 54 on the side that is close to each other. Each water outlet pipe 54 is rotatably connected to a control valve 55 on the side that is far away from each other.

[0032] It should be noted that when testing the dissolution rate of nutritional rice flour, it is necessary to consider whether the dissolution of nutritional rice flour will be affected under different water volume conditions. When different water volumes need to be injected for testing, the water pump 52 is started and the three control valves are rotated at different angles. At the same time, the water pump 52 draws clean water through the water suction pipe 53 and sends it into the water outlet pipe 54, so that the amount of water injected into the dissolution container by the three water outlet pipes 54 is different. This allows for testing the effect of different water volumes on the dissolution rate of nutritional rice flour. After the water is injected, the water pump 52 and the control valve 55 are turned off. In summary, by using the water pump 52 to draw clean water from the water storage tank 51 and controlling the water flow of the water outlet pipe 54 by the control valve 55, it is convenient for testers to conduct simultaneous testing on the effect of different water volumes on the dissolution rate of nutritional rice flour, thus improving testing efficiency.

[0033] like Figure 1 , Figure 4 and Figure 6 As shown, the temperature control mechanism 6 includes a fixed base 61, a rotating plate 62, a heating tube 63, and an outer frame 64. The guide plates 3 are all bolted to the fixed base 61 on the side away from each other. The fixed base 61 is rotatably connected to two rotating plates 62 on the side away from each other. The rotating plates 62 are connected to the heating tube 63 on the side close to each other. The rotating plates 62 are connected to the outer frame 64 on the side away from each other.

[0034] It should be noted that, in addition to the amount of water, the temperature difference during the dissolution process also needs to be considered when affecting the dissolution rate of nutritional rice flour. Therefore, during the test, the dissolution container is limited by the clamping action between the rotating plates 62. When testing the dissolution rate under different water volumes, in order to maintain a single variable, the heating tube 63 needs to be kept at the same temperature to heat the dissolution container, thus improving the accuracy of the test. Even when the amount of water in the dissolution container is the same, the prerequisite of maintaining a single variable is still upheld, and the heating tube 63 needs to be kept at different temperatures to heat the dissolution container. After the test, when the tester opens the rotating plates 62, the outer frame 64 can effectively insulate against heat, preventing the tester from being burned. In summary, the clamping and fixing of the dissolution container by the rotating plates 62 prevents the dissolution container from shaking, and at the same time, it can assist in testing the dissolution rate of nutritional rice flour under different temperature conditions with the same amount of water or different water volumes with the same temperature.

[0035] like Figure 1 and Figure 5 As shown, it also includes a splash-proof mechanism 7, which includes a spring 71, a top cover 72 and a rubber layer 73. The upper part of the stirring assembly 4 is connected to the spring 71, the bottom of the spring 71 is connected to the top cover 72, and the bottom of the top cover 72 is connected to the rubber layer 73.

[0036] It should be noted that during the stirring test of the nutritional rice flour, in order to prevent the nutritional rice flour from splashing during the stirring process, as the stirring component 4 slides downward, it will drive the upper cover 72 downward and into contact with the dissolving container, thus covering and sealing the top of the dissolving container. At the same time, under the action of the rubber layer 73, the friction between the upper cover 72 and the dissolving container can be increased, enhancing the sealing effect. The spring 71 will always provide cushioning and pushing to the upper cover 72 during this process, making the upper cover 72 fit more tightly with the dissolving container. In summary, by driving the upper cover 72 to move through the stirring component 4, the upper cover 72 fits with the dissolving container, covering and sealing the top of the dissolving container, preventing the nutritional rice flour from splashing during the stirring process, and thus avoiding differences in the original quantity of the test subject.

[0037] like Figure 1 and Figure 6 As shown, it also includes an opening and closing mechanism 8, which includes a first connecting rod 81, a guide frame 82, a support rod 83, an elastic rope 84, a guide rod 85, a sliding frame 86, a locking rod 87, and a torsion spring 88. Two symmetrically distributed support rods 83 are connected to the upper outer side of the mounting plate 1. The top of each support rod 83 is connected to a guide frame 82 when rotating. A torsion spring 88 is connected between each guide frame 82 and an adjacent support rod 83. The bottom of each rotating plate 62 is connected to a first connecting rod 81, which is slidably connected to an adjacent guide frame 82. Two guide rods 85 are connected to the sides of each guide plate 3 that are close to each other. A sliding frame 86 is slidably connected between adjacent guide rods 85. An elastic rope 84 is connected between each guide frame 82 and an adjacent sliding frame 86. Two locking rods 87 are connected to the parts of each stirring assembly 4 that are close to each other. The locking rods 87 are slidably connected to the adjacent sliding frame 86.

[0038] It should be noted that during the rotation and opening of the rotating plate 62, to avoid direct contact between the test personnel and the rotating plate 62, when the stirring component 4 moves upward, it will cause the locking rods 87 to move upward as well. This causes the corresponding sliding frames 86 to slide towards each other, thereby causing the elastic ropes 84 to rotate and unfold the adjacent guide frames 82 towards each other. The guide frames 82 will then cause the first connecting rods 81 to move towards each other, causing the rotating plate 62 to automatically rotate and unfold. The torsion springs 88 will deform under force, achieving the effect of automatically unfolding the rotating plate 62. Afterward, as the stirring component 4 slides downward, it will resume operation. When the position is correct, the lever 87 will cause the sliding frame 86 to slide and reset to the side away from each other. This will cause the elastic ropes 84 to stop pulling the guide frame 82. Under the action of the torsion spring 88, the guide frames 82 will rotate and close to the side closer to each other. This will cause the first connecting rod 81 to drive the adjacent rotating plate 62 to rotate and close. In summary, the movement of the stirring assembly 4 causes the lever 87 to drive the corresponding sliding frame 86 to slide. At this time, the elastic ropes 84 will pull the corresponding guide frame 82 to rotate, so that the rotating plate 62 can open and close automatically, avoiding direct contact between the test personnel and the rotating plate 62, thus preventing unnecessary damage.

[0039] like Figure 1 and Figure 7 As shown, it also includes a wall scraping mechanism 9, which includes a second connecting rod 91, a scraper 92 and a float 93. The stirring assembly 4 is slidably connected to the second connecting rod 91, and the two ends of the second connecting rod 91 are connected to the scraper 92. The scraper 92 is used to scrape the nutrient rice powder floating on the water surface. Two floats 93 are connected to the second connecting rod 91.

[0040] It should be noted that during the mixing of the nutritional rice flour, the rice flour may float on the water surface, preventing it from being fully mixed. Therefore, after water is poured into the dissolving container, the float 93 will lift the second connecting rod 91 upwards, causing it to float on the corresponding water surface. Then, as the stirring component 4 begins to stir the nutritional rice flour, it will rotate the second connecting rod 91, causing the scraper 92 to scrape the floating nutritional rice flour, ensuring thorough mixing. In summary, the float 93 lifts the second connecting rod 91 to float on the water surface, and the stirring component 4 rotates the second connecting rod 91, causing the scraper 92 to scrape the floating nutritional rice flour, ensuring thorough mixing and dissolution.

[0041] like Figure 1 and Figure 8As shown, it also includes a stabilizing mechanism 10, which includes a connecting frame 101 and a limiting plate 102. The connecting frames 101 are all bolted to the middle part of the guide plate 3 on the side away from each other. The side away from each other of the connecting frames 101 is welded with a limiting plate 102. The limiting plates 102 are all arc-shaped structures that can fit the dissolving container for limiting.

[0042] It should be noted that during the stirring of the nutritional rice flour, the dissolving container will shake. The limiting plate 102 fits against the dissolving container to limit the movement of the dissolving container and prevent it from shaking during the stirring of the rice flour, thus affecting the stability of the dissolving container.

[0043] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
