Description

Technical Field

[0001] The invention relates to the technical field of viscosity detection, and in particular to a device and method for detecting the viscosity of a yam extract. Background Art

[0002] Yam contains abundant polysaccharides, such as mannan, and a certain amount of protein. These macromolecules are intertwined in the extract to form a network structure, which increases the viscosity of the liquid. In the yam processing technology, it is necessary to test the viscosity of the extract to ensure that the quality of different batches of products remains consistent.

[0003] A rotational viscometer is usually used to test the viscosity of yam extract. In actual operation, first, place the container containing yam extract under the rotor of the rotational viscometer. Then, slowly immerse the rotor of the rotational viscometer into the extract. After the rotor stabilizes, turn on the viscometer, select the appropriate speed, and read the viscosity value displayed on the viscometer.

[0004] However, since yam is rich in starch, starch may dissolve into the extract during the extraction process. After the extract is left for a period of time, starch molecules may aggregate and precipitate, and the solubility of starch decreases, causing precipitation and stratification of the yam extract inside the container. Precipitation and stratification will make the structure inside the extract uneven, causing the ratio of solvent and solute to change in different areas, resulting in a decrease in the viscosity of the upper clear liquid and a relatively high concentration in the bottom sediment layer, thereby reducing the accuracy of rotor rotation detection. Summary of the invention

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Example 1: Please refer to Figure 1 - Figure 4 A device for detecting the viscosity of yam extract comprises a workbench 1, a screw slide 2 installed at the top of the workbench 1, and a control box 3 installed at one side of the slide seat of the screw slide 2, a detection rotor 4 is fixed at the bottom end of the control box 3, a positioning frame 5 is fixedly connected to one side of the workbench 1 near the bottom end of the detection rotor 4, a support plate 6 is arranged at one side of the top end of the positioning frame 5, and a limiting mechanism is arranged at the top end of the support plate 6;

[0041] The limiting mechanism includes a limiting clamping plate 8, which is symmetrically arranged on the outside of one side of the top of the support plate 6, and a rotating shaft 10 is longitudinally penetrated and fixed inside the edge of one side of the limiting clamping plate 8, a heating mechanism is provided on one side of the limiting clamping plate 8, a positioning rod 7 is longitudinally fixed on one side of the bottom end of the control box 3, and an oscillation mechanism is provided on the bottom end of the support plate 6;

[0042] The oscillation mechanism includes a driving component, a longitudinal oscillation component and a transverse oscillation component;

[0043] The driving assembly includes a rotating rod 24 , and the rotating rod 24 is installed on the outside of the bottom end of the workbench 1 close to the supporting plate 6 for transverse rotation.

[0044] The limit clamping plate 8 is arranged in a semicircular shape when viewed from above, and the bottom end of the rotating shaft 10 is rotatably installed on the outside of the bottom side of the support plate 6, and a transmission component is provided on the bottom side of the support plate 6 close to the rotating shaft 10; the transmission component includes a limit seat 12 and a transmission rack 13, the limit seat 12 is fixedly installed on the bottom side of the support plate 6, and the transmission rack 13 is slidably engaged and installed on one side of the limit seat 12, and a transmission gear 11 is fixedly installed on the bottom end of the rotating shaft 10, and the two transmission gears 11 are meshed and connected, and one side of one of the transmission gears 11 is meshed and connected with one side of the transmission rack 13, and an extrusion component is provided on one side of the transmission rack 13.

[0045] The extrusion assembly includes a contact plate 9, which is fixedly mounted on the outside of the side of the positioning rod 7 close to the transmission rack 13, and the bottom end of the contact plate 9 is arranged in an arc slope shape. A contact roller 14 is rotatably mounted on one end of the transmission rack 13 close to the contact plate 9, and a reset assembly is arranged on the side of the transmission rack 13 away from the contact roller 14.

[0046] The reset assembly includes a guide rod 16, which is fixedly mounted on the outside of the side of the transmission rack 13 away from the contact plate 9. An auxiliary block 15 is slidably mounted on the outside of one side of the guide rod 16, and one end of the auxiliary block 15 is fixedly mounted on the bottom side of the support plate 6. A reset spring 17 is sleeved through the outside of the guide rod 16, and the two ends of the reset spring 17 are respectively mounted on one side of the auxiliary block 15 and the transmission rack 13.

[0047] In this embodiment, when the yam extract is tested, the container containing the yam extract is first placed on the top of the support plate 6, and then the screw slide 2 constructed in the prior art is started, so that the slide seat on one side of the screw slide 2 starts to drive the control box 3, the detection rotor 4 and the positioning rod 7 to slowly descend. When the positioning rod 7 descends to a certain position, the arc surface on one side of the bottom end of the contact plate 9 contacts the contact roller 14 on one side. As the positioning rod 7 continues to be squeezed and lowered, the contact roller 14 is squeezed and drives the transmission rack 13 inside the limit seat 12. When moving, the transmission rack 13 will drive one of the meshing transmission gears 11 on one side to rotate, thereby driving the other meshing transmission gear 11 to rotate, so that the two rotating shafts 10 and the two symmetrically arranged limit clamps 8 begin to rotate toward the two sides of the container of yam extract, thereby clamping and limiting the container filled with yam extract, thereby ensuring the stability of the subsequent container filled with yam extract during oscillation, and at the same time, the contact plate 9 of the subsequent positioning rod 7 will always contact with the contact roller 14 when it descends, ensuring stable clamping.

[0048] It should also be noted that when the detection is completed, the positioning rod 7 begins to move back and reset. When the positioning rod 7 drives the contact plate 9 to move back to a certain position synchronously, the bottom end of the contact plate 9 is disengaged from one side of the contact roller 14, so that the contact roller 14 loses its squeezing force. At this time, the originally compressed reset spring 17 begins to rebound, thereby driving the transmission rack 13 to move back and reset synchronously, so that the symmetrically arranged limit clamps 8 rotate and reset, so that the clamped container can be released, thereby facilitating the pick-and-place operation.

[0049] Example 2: Please refer to Figure 5 - Figure 6 The present embodiment further explains the first embodiment, the temperature increasing mechanism comprises a heating wire 18, the heating wire 18 is embedded in the interior of the limiting clamp 8, the power connection end of the heating wire 18 is connected to a conducting block 19, the conducting block 19 is fixedly mounted on the outside of the top side of the limiting clamp 8, a support frame 20 is symmetrically fixedly mounted on the top side of the support plate 6, a mounting block 21 is transversely fixedly mounted on one side of the support frame 20 close to the conducting block 19, and a conducting block 22 is fixedly mounted through the inside of the mounting block 21 close to the conducting block 19.

[0050] In this embodiment, when the two limit clamps 8 rotate synchronously and the limit mechanism operates to clamp and limit the container, the conductive block 19 at the top of the limit clamp 8 and the conductive block 2 22 at the bottom of the mounting block 21 are in contact and fit, thereby starting to energize the heating wire 18 on the inner wall of the limit clamp 8, so that the heating wire 18 is energized to generate heat, thereby increasing the temperature of the yam extract inside the container. The heating can increase the thermal motion of the molecules, so that the starch molecules are redissolved in the extract, reducing precipitation and stratification, and improving the uniformity and stability of the extract.

[0051] It should also be noted that when the limit clamp 8 rotates and resets, the conductive block 19 and the conductive block 22 at the bottom of the mounting block 21 will be separated again, thereby cutting off the power to the heating wire 18 and automatically performing the switch control to avoid energy waste or component damage caused by forgetting to turn off.

[0052] It should also be noted that when the device is in use, the conductive block 22 needs to be connected to an external power source to ensure that power can be provided to the heating wire 18. At the same time, a temperature control mechanism disclosed in the prior art can be added during production to ensure that the heating wire 18 does not generate excessive heat and performs constant temperature heating.

[0053] Example 3: Please refer to Figure 7 - Fig.10 This embodiment further explains the second embodiment. A limit gear 25 is fixedly installed on the outside of one side of the rotating rod 24 . A limit rack 23 is provided on the bottom end of the positioning rod 7 near the limit gear 25 .

[0054] The longitudinal oscillation component includes a fixed block 26, which is longitudinally slidably mounted inside the positioning frame 5 on one side of the bottom end of the support plate 6. The fixed block 26 is an I-shape when viewed from the front. A limiting groove 27 is horizontally penetrated inside the bottom end of the fixed block 26, and an eccentric disc 28 is penetrated and fixed outside the side of the rotating rod 24 located inside the limiting groove 27.

[0055] The lateral oscillation assembly includes a positioning block 29, one end of the positioning block 29 is fixedly installed with one end of the rotating rod 24, and the other end of the positioning block 29 is rotatably connected to a pull rod 30, a fixing frame 31 is fixedly connected to one side of the positioning frame 5 near the top end of the pull rod 30, a connecting rod 32 is provided on one side of the fixing frame 31, and the inner middle position of the connecting rod 32 is rotatably installed on the outside of one side of the fixing frame 31 through a limiting shaft, the bottom end of the connecting rod 32 is rotatably connected to one end of the pull rod 30, and the top end of the connecting rod 32 is rotatably connected to a pull rod 2 33.

[0056] A slide groove 34 is embedded inside the top of the fixed block 26, and a slider 35 is installed inside the slide groove 34 for horizontal sliding engagement. The top of the slider 35 is fixedly connected to the bottom of the support plate 6, and one side of the slider 35 is rotatably connected to one end of the pull rod 2 33.

[0057] In this embodiment, when the positioning rod 7 continues to descend to a certain height, the bottom end of the limit rack 23 on one side of the positioning rod 7 will mesh with the limit gear 25 on one side of the rotating rod 24. As the positioning rod 7 continues to descend, the limit gear 25 and the rotating rod 24 will be driven to rotate. The rotation of the rotating rod 24 will drive the eccentric disk 28 on one side to rotate. The rotation of the eccentric disk 28 and the limit of the limit groove 27 will cause the sliding fixed block 26 to reciprocate up and down, so that the fixed block 26 performs a short-distance longitudinal reciprocating motion on one side of the positioning frame 5, thereby driving the top support plate 6 and the clamped container to perform synchronous longitudinal reciprocating motion and oscillation. At the same time, the rotating rod 24 will drive the positioning block 29 on one side to rotate synchronously. The step rotation drives the pull rod 1 30 on one side to make reciprocating lateral movement left and right, and drives the connecting rod 32 to rotate back and forth on one side of the fixed frame 31, thereby driving the pull rod 2 33 to make reciprocating lateral movement left and right, and cooperates with the installation of the slide groove 34 and the slider 35, so that the left and right lateral movement of the pull rod 2 33 can drive the support plate 6 and the container clamped at the top to make reciprocating lateral movement and oscillation, so that when the device is in use, it can drive the clamped yam extract container to perform multi-directional oscillation disturbance, and through the multi-directional oscillation disturbance, the sedimentation stratification can be effectively broken, so that the medium of the yam extract sedimentation stratification can be re-mixed, thereby avoiding the situation where the accuracy of rotor rotation detection is reduced due to sedimentation stratification, and the overall use effect is better.

[0058] It should also be noted that when the positioning rod 7 continues to descend to a certain height, the limit rack 23 on one side of the positioning rod 7 loses engagement with the limit gear 25, so that the container containing the yam extract stops shaking and remains stable. After that, the detection rotor 4 descends to a certain height and is inserted into the yam extract to rotate to complete the detection.

[0059] The present invention also provides a detection method of a yam extract viscosity detection device, comprising the following steps:

[0060] S1: First, place the container containing yam extract on the top of the support plate 6, then start the screw slide 2 to drive the control box 3, the detection rotor 4 and the positioning rod 7 to slowly descend;

[0061] S2: The positioning rod 7 triggers the limit mechanism to operate during the descending process, thereby automatically clamping and limiting the container on the top of the support plate 6;

[0062] S3: After the limiting mechanism operates to clamp and limit the container, it will simultaneously drive the temperature increasing mechanism to operate, thereby increasing the temperature of the yam extract inside the container;

[0063] S4: As the positioning rod 7 continues to descend, it drives the oscillation mechanism to operate, thereby driving the container containing the yam extract to perform multi-directional oscillation disturbance;

[0064] S5: When the positioning rod 7 is lowered to a certain extent, the oscillation mechanism stops running, and the detection rotor 4 at the bottom of the control box 3 is inserted into the yam extract, and then a rotation detection is performed.

[0065] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0066] 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.
