Description

Technical Field

[0001] The utility model belongs to the technical field of fruit juice production, and in particular relates to a rotor and a rotational viscometer. Background Art

[0002] In juice production, the taste of the finished juice is not only affected by sweetness and acidity, but also by its viscosity. Juice with high viscosity is more viscous, difficult to flow, and tastes relatively greasy. Therefore, measuring the viscosity of juice can provide important information for making better juice, and the device commonly used to measure juice viscosity is a rotational viscometer.

[0003] However, there are some problems in the prior art: the rotors used in the existing rotational viscometers are mostly cylindrical solid steel blocks, which have a high center of gravity and are unstable, and are prone to shaking when rotating, thus affecting the test progress. Moreover, when the cylindrical rotor is placed in the juice and rotated for a certain period of time, the rotation of the rotor will not be affected by the shear stress of the juice, resulting in the inability to accurately measure the viscosity of the juice fluid. Therefore, we propose a rotor and a rotational viscometer. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a rotor and a rotational viscometer, by dividing the rotor into two parts, so that the center of gravity of the rotor is lowered, thereby ensuring the stability of the rotor when rotating.

[0005] The utility model is implemented in this way: a rotor comprises a rotor head and a rotor tail, wherein the rotor head is conical and the rotor tail is trumpet-shaped, the rotor head and the rotor tail are connected in one piece, blades are fixedly connected at both sides of the rotor head, and a connecting rod is fixedly connected at the upper end of the rotor tail.

[0006] Optionally, the rotor head is a solid structure and the rotor tail is a hollow structure.

[0007] Optionally, the blades are arranged in multiple groups, and the multiple groups of blades are evenly distributed in a straight line on both sides of the rotor.

[0008] Optionally, the size of the paddle blade gradually increases from top to bottom, and the angle of the paddle blade gradually increases from top to bottom.

[0009] A rotary viscometer comprises the above-mentioned rotor and a base, wherein the upper end of the base is fixedly connected to a support rod, the support rod is movably connected to a moving body, and the lower end of the moving body is fixedly connected to a motor.

[0010] Optionally, a thread is provided on the upper end of the connecting rod, a threaded hole corresponding to the connecting rod is provided at the movable end of the motor, and the connecting rod is threadedly connected to the motor.

[0011] Optionally, a slide bar is sleeved on the support rod, and the slide bar slides on the support rod. A hole is opened in the middle of the slide bar, and a locking screw is arranged in the hole. The locking screw is used to fix the slide bar, and the mobile body is fixed on the slide bar.

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

[0013] 1. The utility model divides the rotor into two parts, one part is a hollow trumpet-shaped rotor tail, and the other part is a solid conical rotor head. The rotor tail and the rotor head are connected in one piece, which moves the center of gravity of the rotor downward and ensures the stability of the rotor.

[0014] 2. The utility model adds blades to the rotor, so that the rotor will not lose the shear force between the rotor and the juice even if it rotates for a long time, making the measurement result more accurate.

[0015] 3. The blade size and angle gradually increase from top to bottom, further moving the center of gravity of the rotor downward and improving the stability of the rotor.

[0022] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0023] like Figures 1 to 4As shown, a rotor and a rotational viscometer provided by an embodiment of the utility model include a rotor head 1 and a rotor tail 2, the rotor head 1 is conical, the rotor tail 2 is trumpet-shaped, the rotor head 1 and the rotor tail 2 are integrally connected, the rotor head 1 and the rotor tail 2 are both made of stainless steel, and the rotor head 1 and the rotor tail 2 need to be completely immersed in juice when in use, so the rotor head 1 and the rotor tail 2 are both made of stainless steel to ensure the use time.

[0024] The rotor head 1 is designed to be conical and the rotor tail 2 is designed to be trumpet-shaped in order to move the center of gravity of the rotor downward and maintain the center of gravity of the rotor on the rotor head 1. In this way, the rotor will not shake when being rotated by the motor 4, thereby ensuring the stability of the rotor and making the measurement result more accurate.

[0025] Paddle blades 3 are fixedly connected to both sides of the rotor 1. The function of the paddle blades 3 is to increase the shear stress between the rotor and the juice. When the rotor is placed in the juice and rotated for a period of time, the shear stress between the rotor and the juice will be reduced or even disappear, resulting in the measured juice viscosity value being no longer accurate. Therefore, it is very necessary to set the paddle blades 3 on the rotor.

[0026] There are multiple groups of blades 3, which are evenly distributed in a straight line on both sides of the rotor 1. The purpose of evenly distributing the blades 3 in a straight line on both sides of the rotor 1 is to ensure that the blades 3 will not affect the rotation of the rotor during the rotation of the rotor, thereby ensuring the stability of the rotor rotation.

[0027] The size of the blade 3 of the paddle 3 increases gradually from top to bottom, and the angle of the blade 3 increases gradually from top to bottom. The purpose of gradually increasing the size of the blade 3 from top to bottom is to make the contact area between the lower blade 3 and the juice larger, so that the resistance between the blade 3 and the juice is larger, and the center of gravity of the rotor is further moved downward to ensure the stability of the rotor when it rotates. The angle of the blade 3 increases gradually from top to bottom, also in order to make the contact area between the lower blade 3 and the juice larger, and the resistance between the blade 3 and the juice is larger.

[0028] The upper end of the rotor tail 2 is fixedly connected with a connecting rod 5, and the connecting rod 5 is used to connect the rotor to the rotational viscometer.

[0029] A rotational viscometer includes the above-mentioned rotor and a base 6. The base 6 is a rectangular parallelepiped. Of course, its shape is not limited to a rectangular parallelepiped, and can also be other shapes such as a cube. The function of the base 6 is to maintain the stability of the rotational viscometer and place the experimental liquid. After the juice to be tested for viscosity is placed in a container, the container is placed on the base 6 and waits for measurement.

[0030] A support rod 7 is fixedly connected to the base 6. The support rod 7 is a cylindrical long rod made of stainless steel. Of course, its shape is not limited to a cylindrical shape, and it can also be other shapes such as a rectangle. A slide rod 9 is sleeved on the support rod 7, and the slide rod 9 can slide on the support rod 7. The position of the mobile body 8 can be adjusted by adjusting the position of the slide rod 9.

[0031] A hole is provided in the middle of the slide bar 9, and a locking screw 10 is provided in the hole. The locking screw 10 is used to fix the slide bar 9, and the mobile body 8 is fixed on the slide bar 9. When the height of the mobile body 8 needs to be adjusted, the locking screw 10 is loosened, and the slide bar 9 can slide on the support rod 7 to adjust the height of the mobile body 8. After the adjustment is completed, the locking screw 10 is tightened, and the slide bar 9 is locked on the support rod 7 and cannot slide, and the mobile body 8 is also fixed in the current position and cannot move.

[0032] The motor 4 is fixedly connected to the lower end of the mobile body 8, the upper end of the connecting rod 5 is provided with a thread, the movable end of the motor 4 is provided with a threaded hole corresponding to the connecting rod 5, the connecting rod 5 is threadedly connected to the motor 4, and the motor 4 is used to drive the rotor to rotate.

[0033] A processor is provided in the mobile body 8 to analyze the shear stress on the rotor to obtain the viscosity value of the juice. A display screen is provided on the surface of the mobile body 8 to display the detected viscosity value of the juice. A battery and a circuit are also provided in the mobile body 8 to power the rotational viscometer.

[0034] The working principle of the utility model is as follows:

[0035] Before using the utility model, the juice to be tested is placed in a container, and then the container is placed on the base 6. At this time, the locking screw 10 is loosened to adjust the height of the mobile body 8 so that the entire rotor is immersed in the juice. The locking screw 10 is then tightened to lock the mobile body 8 at the current position, and then the motor 4 is started to drive the rotor to rotate to measure the viscosity of the juice. During the rotation process, the shape of the rotor and the blades 3 on the rotor ensure the stability of the rotor. The blades 3 also enable the rotor to rotate for a long time and still maintain the shear stress between the rotor and the juice, thereby ensuring the stability of the rotor rotation.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
