Description

Technical Field

[0001] This utility model relates to the field of food testing technology, and in particular to a rice viscosity measuring device. Background Technology

[0002] Rice, also known as paddy rice or rice paddy, is an edible grain, an annual herbaceous plant that thrives in warm and humid conditions. In southern China, it is commonly called "rice" or "grain." The hulled grain is rice. Rice is one of my country's main food crops, with a long history of cultivation and a large planting area. Rice is not only a food source but also a raw material for brewing wine and making maltose. The viscosity of rice directly affects the softness, elasticity, and palatability of cooked rice, and the processing direction of rice can be determined based on its viscosity. Rice testing can also determine whether rice has become stale or spoiled, avoiding improper storage that could affect its quality.

[0003] The detection of rice viscosity usually requires grinding rice into powder and passing it through a 100-mesh sieve. After preparing a suspension according to a standard ratio (e.g., 3g rice powder + 25ml water), the suspension is poured into a test tank and placed in an instrument. The test tank is heated to simulate the cooking process (e.g., 30℃-90℃-50℃). The stirring mechanism is used to run at a constant speed, and the viscosity is measured in conjunction with a sensor.

[0004] In existing technologies, viscosity measurements are required for different types and proportions of rice for testing purposes. However, the rice flour and water need to be thoroughly mixed during the measurement process. But most stirring blades have a relatively simple shape, resulting in poor mixing effect and gelatinization during the mixing and heating process, which leads to deviations in viscosity measurement. Therefore, we urgently need a rice viscosity measuring device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem of poor mixing effect in the prior art, and to propose a rice viscosity measuring device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A rice viscosity measuring device includes a base and a mounting base rotatably connected to the base. A testing barrel is disposed within the mounting base. The device also includes: a bracket symmetrically mounted on the base; a rotating rod rotatably connected to the bracket; a stirring blade fixedly mounted on the rotating rod; several protrusions mounted on the inner wall of the testing barrel, which cooperate with the stirring blade; a vertical frame slidably connected to the base; a mounting plate vertically mounted on the vertical frame; a rotating rod rotatably connected to the mounting plate; a stirring blade magnetically connected to the upper end of the rotating rod; and a spiral blade fixedly mounted to the lower end of the rotating rod.

[0008] To enable the stirring blades to rotate, preferably, the support has a placement groove, and the inner wall of the placement groove is fitted with a magnetic buckle, and the rotating rod is magnetically connected to the magnetic buckle.

[0009] To improve the mixing effect, preferably, there are at least two sets of protrusions arranged in a ring at equal intervals. When the stirring blade contacts the protrusion, the rotating rod rotates accordingly.

[0010] In order to move the rotating rod two into the detection barrel, preferably, a guide rail one is fixedly installed on the base, the upright is slidably connected in the guide rail one, a guide rail two is fixedly installed on the upright, and the mounting plate is slidably connected in the guide rail two.

[0011] To improve the mixing effect, preferably, the included angle between the plane of the second stirring blade and the axis of the second rotating rod is in the range of 30°-45°.

[0012] In order to drive the mounting base to rotate, preferably, a drive motor is fixedly mounted on the base, and the output end of the drive motor is fixedly mounted to the mounting base.

[0013] In order to drive the rotating rod two to rotate, preferably, a driving motor two is fixedly installed on the mounting plate, and the output end of the driving motor two is fixedly installed with the rotating rod two.

[0014] Compared with the prior art, this utility model provides a rice viscosity measuring device, which has the following beneficial effects:

[0015] 1. This rice viscosity measuring device, through the setting of rotating rod one and rotating rod two, when the mounting base rotates, the protrusion contacts the stirring blade one, and causes rotating rod one to rotate accordingly, thereby forming a local vortex in the testing barrel, changing the running trajectory of the fluid in the testing barrel. The drive motor two drives rotating rod two to rotate. Utilizing the cooperation between stirring blade two and spiral blade, the liquid in the testing barrel is made into a vortex, and the sediment on the bottom wall of the testing barrel is also lifted upward. Combined with the local vortex on both sides, the mixing effect is effectively improved.

[0016] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This invention improves the mixing effect of rice flour and water and enhances the detection accuracy. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Example:

[0025] Reference Figures 1-4A rice viscosity measuring device includes a base 1 and a mounting base 2 rotatably connected to the base 1. A drive motor 17 is fixedly mounted on the base 1, and the output end of the drive motor 17 is fixedly mounted to the mounting base 2. A test barrel 3 is provided on the mounting base 2. A heating device is provided inside the test barrel 3 to simulate the cooking process. The heating device has an independent power supply function. A power switch and a power supply are provided on the test barrel 3 to provide heating function. During the heating process, the fluid temperature successively reaches 30℃→90℃→50℃. The device also includes: a bracket 4 symmetrically mounted on the base 1. The bracket 4 has a placement groove 5. A magnetic buckle 6 is installed on the inner wall of the placement groove 5. A rotating rod 7 is magnetically connected to the magnetic buckle 6. A stirring blade 8 is fixedly mounted on the rotating rod 7. A plurality of protrusions 14 are installed on the inner wall of the test barrel 3. There are at least two sets of protrusions 14. The components are arranged in a ring at equal intervals. When the stirring blade 8 contacts the protrusion 14, the rotating rod 7 rotates and slides on the support frame 9 on the base 1. The support frame 9 is equipped with a mounting plate 10 that is raised and lowered. The drive motor 18 is fixedly installed on the mounting plate 10, and the output end of the drive motor 18 is fixedly installed on the rotating rod 11. The rotating rod 11 is rotatably connected to the mounting plate 10. The upper end of the rotating rod 11 is magnetically connected to the stirring blade 12, and the lower end of the rotating rod 11 is fixedly installed with the spiral blade 13. When the rotating rod 11 rotates, the stirring blade 12 pushes the fluid laterally towards the detection tank 3 to promote overall mixing. The spiral blade 13 lifts the fluid at the bottom of the detection tank 3 upwards. Together with the stirring blade 12, the mixing effect can be effectively improved, starch agglomerates can be effectively broken, and viscosity detection deviation caused by undissolved particles in the local area during the gelatinization process can be avoided.

[0026] Driven by drive motor 17, mounting base 2 rotates, protrusion 14 contacts stirring blade 8, and rotating rod 7 follows suit, thereby forming a local vortex in detection tank 3, changing the trajectory of the fluid in detection tank 3. Drive motor 18 drives rotating rod 11 to rotate. With the cooperation of stirring blade 12 and spiral blade 13, the liquid in detection tank 3 is vortexed, and the sediment on the bottom wall of detection tank 3 is lifted upward. Combined with the local vortex on both sides, the mixing effect is effectively improved.

[0027] At least two sets of stirring blades 8 are arranged equidistantly in a circle on the rotating rod 7. The angle between the plane of stirring blade 12 and the axis of rotating rod 11 is in the range of 30°-45°. The preferred angle of stirring blade 12 is 45°, which can improve the control of the flow field inside the detection tank 3.

[0028] The rotating rod 7 is detachable, which facilitates the replacement or maintenance of the stirring blade 8. The stirring blade 12 on the rotating rod 11 is magnetically connected. If the stirring blade 12 needs to be repaired in the future, only the damaged blade needs to be replaced individually, avoiding the need to replace the whole blade.

[0029] A guide rail 15 is fixedly installed on the base 1, the upright 9 is slidably connected to the guide rail 15, a guide rail 2 16 is fixedly installed on the upright 9, and the mounting plate 10 is slidably connected to the guide rail 2 16.

[0030] In this invention, the operator pours a measured amount of rice flour and water into the testing tank 3. Then, the rotating rod 7 is inserted into the magnetic buckle 6 to complete the installation. The stand 9 is slid along the guide rail 15. After the rotating rod 11 is brought close to the testing tank 3, the mounting plate 10 is slid downwards along the guide rail 16, moving the rotating rod 11 to the middle of the testing tank 3. At this point, the drive motors 17 and 18 are activated, and the mounting base 2 drives the testing tank 3 to rotate. After the protrusion 14 contacts the stirring blade 8, it drives the rotating rod 7 to rotate due to inertia, forming a local vortex within the testing tank 3. The stirring blade 12 on the rotating rod 11 mixes the fluid within the testing tank 3. The spiral blade 13 lifts the sediment from the bottom wall of the testing tank 3 upwards, reducing the amount of undissolved particles sticking to the bottom and further improving the mixing effect. This process is then combined with an external detector for testing.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
