Description

Technical Field

[0001] This invention relates to the field of sugar alcohol detection technology, specifically a sugar alcohol purity detection device. Background Technology

[0002] Sugar alcohols are an important class of functional sweeteners, widely used in the food, pharmaceutical and health product fields. In the quality control of sugar alcohol products, purity detection is one of the key links. High performance liquid chromatography using a differential refractive index detector is currently the mainstream method for detecting the purity of sugar alcohols. Its detection accuracy largely depends on the mixing effect of sugar alcohols and solvents during sample pretreatment.

[0003] In the prior art, the equipment used for mixing sugar alcohol solutions before purity testing mainly includes stirred tanks and high-shear dispersers. Traditional stirred tanks usually use single-stage or multi-stage stirring paddles. During operation, the motor drives the stirring shaft to rotate, and the stirring paddles installed on the shaft transfer mechanical energy to the material in the tank, forming a high-turbulence mixing zone near the paddles and generating a high-speed jet to drive the material to circulate throughout the container, thereby shearing and breaking down the sugar alcohol particles, so that they can fully contact and uniformly mix with the solvent.

[0004] However, the above-mentioned sample mixing preparation process before testing has the following shortcomings: First, under the influence of gravity, sugar alcohol particles tend to settle at the bottom of the container, forming a "stirring blind zone" that the stirring paddle cannot reach, resulting in the bottom particles not being effectively mixed for a long time; Second, traditional techniques, by increasing the number of stirring stages or increasing the rotation speed, have not fundamentally improved the contact problem between the particles and the stirring paddle. The movement of sugar alcohol particles in the solution is still mainly dominated by gravity, and large particles tend to settle at the bottom or deviate from the stirring core area.

[0005] In addition, high-speed stirring can easily cause "wall accumulation" on the container wall due to centrifugal force. Particles rotate along the wall and have difficulty entering the stirring zone, which further reduces the mixing efficiency. The reduction in the mixing efficiency of sugar alcohol samples means an increase in the overall purity detection time, ultimately resulting in lower detection efficiency.

[0006] Therefore, how to increase the effective contact frequency between sugar alcohol particles and the stirring paddle, avoid particle deposition and wall accumulation, and thus improve the uniformity of sugar alcohol solution mixing is a technical problem that needs to be solved in the current sugar alcohol purity detection process. Summary of the Invention

[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a sugar alcohol purity detection device, including a stirring vessel, the stirring vessel being hourglass-shaped with a small diameter at the waist and large diameters at both ends, the device also including a shaking mechanism for driving the stirring vessel to move linearly back and forth in various directions, and a stirring mechanism for shearing and mixing sugar alcohol particles.

[0008] The shaking mechanism includes a rotating platform, on which a U-shaped frame is connected via a movable component. A tilting frame is rotatably mounted on the U-shaped frame and is fixedly connected to the mixing vessel for reciprocating inversion of the mixing vessel.

[0009] The stirring mechanism includes two stirring paddles symmetrically arranged inside the stirring vessel.

[0010] The reciprocating inversion of the mixing vessel causes the sugar alcohol particles inside to intermittently pass through the waist of the mixing vessel under the action of gravity. The moving component moves the mixing vessel in various directions, causing the sugar alcohol particles to intermittently pass through the axis of the mixing vessel under the action of inertia, thereby forcing the stirring paddle to contact the sugar alcohol particles.

[0011] By inverting and moving the stirring vessel, sugar alcohol particles are intermittently passed through the waist and axis of the stirring vessel, thus forcibly shearing the sugar alcohol particle mixture solution.

[0012] Preferably, the moving component includes a guide rail plate fixedly mounted on a rotary table, a movable plate slidably disposed on the upper side of the guide rail plate along its radial direction, and the upper side of the movable plate being rotatably connected to the U-shaped frame.

[0013] Preferably, a synchronous motor is fixedly installed on the U-shaped frame, the output shaft of the synchronous motor is fixedly connected to the moving disk, and the synchronous motor and the rotary table rotate synchronously in opposite directions.

[0014] Preferably, the rotary table drives the moving disk to rotate in the forward direction via the guide rail disk, while the synchronous motor drives the moving disk to rotate in the reverse direction at the same speed, so that the U-shaped frame does not rotate.

[0015] Preferably, two symmetrically arranged hydraulic cylinders are fixedly installed on the guide rail disk, and the output shafts of the two hydraulic cylinders are fixedly connected to the moving disk.

[0016] Preferably, the telescopic section of one of the hydraulic cylinders extends while the telescopic section of the other hydraulic cylinder retracts simultaneously, so that the two hydraulic cylinders together drive the moving disc to move radially along the guide rail disc.

[0017] Preferably, two hydraulic cylinders are fixedly installed on the tilting frame, and the upper ends of the telescopic sections of the two hydraulic cylinders are fixedly connected with end caps for sealing and fitting the mixing vessel.

[0018] Preferably, the two stirring paddles are rotatably connected to the mixing vessel and the end cover, and the two stirring paddles are located on both sides of the waist of the mixing vessel. An excitation motor for driving the stirring paddles is fixedly connected to the mixing vessel and the end cover.

[0019] Preferably, a geared motor is fixedly installed on the U-shaped frame, and the output shaft of the geared motor is fixedly connected to the rotating shaft of the flipping frame.

[0020] Preferably, the two conical inner walls of the mixing vessel are fixedly provided with circumferentially distributed spiral protrusions. During mixing, the sugar alcohol particles fall along the trajectory of the spiral protrusions under the centrifugal swing of the stirring paddle.

[0021] Preferably, after the sugar alcohol solution is prepared, the sugar alcohol solution in the stirred tank is poured into several sample containers in sequence, and then these sample containers are immediately sent to a differential refractive index detector to detect the purity of the sugar alcohol in the sample containers using high performance liquid chromatography.

[0022] The beneficial effects of this invention are as follows: First, this invention uses a tilting frame to repeatedly invert the mixing vessel, causing the sugar alcohol particles inside the mixing vessel to intermittently pass through the waist of the mixing vessel under the action of gravity. Utilizing the aggregation capacity formed by the small diameter of the waist and large diameter of both ends of the hourglass-shaped mixing vessel, the sugar alcohol particles are forced to gather towards the center of the mixing vessel and come into contact with the stirring paddle. At the same time, by moving the mixing vessel back and forth in various directions through the moving component, the sugar alcohol particles intermittently pass through the axial position of the mixing vessel under the action of inertia, further forcing the stirring paddle to contact the sugar alcohol particles. This effectively avoids the problem of sugar alcohol particles depositing at the bottom or deviating from the core mixing area in traditional mixing, and significantly improves the mixing efficiency.

[0023] Second, this invention uses a rotary table to drive the moving disk to rotate in the forward direction via a guide rail disk, while a synchronous motor drives the moving disk to rotate in the opposite direction at the same speed. This keeps the U-shaped frame in place and prevents it from rotating. Then, a hydraulic cylinder moves the mixing vessel in a straight line in all directions, so that the sugar alcohol particles gain inertia in multiple directions. This changes the trajectory of the particles from being subject only to gravity or centrifugal force in one direction, and further enhances the contact opportunity between the stirring paddle and the sugar alcohol particles.

[0024] Third, the present invention uses circumferentially distributed spiral protrusions fixed on the conical inner wall of the stirred tank to guide the sugar alcohol particles attached to the wall surface, so that these sugar alcohol particles fall slowly along the trajectory of the spiral protrusions, thereby prolonging the falling time of the sugar alcohol particles on the wall surface of the stirred tank, increasing the contact time and contact frequency between the sugar alcohol particles and the stirring paddle, and further improving the shearing and mixing effect of the stirring paddle on the sugar alcohol particles.

Detailed Implementation

[0032] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Where specific techniques or conditions are not specified in the embodiments, they shall be performed in accordance with the techniques or conditions described in the literature in the art or in accordance with the product manual.

[0033] See Figure 1 and Figure 2 A sugar alcohol purity testing device includes a stirring vessel 1, which is an hourglass shape with a small diameter at the waist and large diameters at both ends. The device also includes a shaking mechanism 2 for driving the stirring vessel 1 to move linearly back and forth in all directions, and a stirring mechanism 3 for shearing and mixing sugar alcohol particles.

[0034] When mixing sugar alcohol particles and solvent, the stirring mechanism 3 continuously stirs the sugar alcohol particles and solvent in the stirred tank 1, while continuously shearing the sugar alcohol particles. The shaking mechanism 2 intermittently inverts the stirred tank 1, causing the sugar alcohol particles in the stirred tank 1 to intermittently pass through the waist of the stirred tank 1 under the action of gravity, thus strengthening the contact mechanism between the sugar alcohol particles and the stirring mechanism 3. At the same time, the shaking mechanism 2 moves the stirred tank 1 back and forth in a straight line in all directions, causing the sugar alcohol particles to intermittently pass through the axial position of the stirred tank 1 under the action of inertia, further strengthening the contact between the stirring mechanism 3 and the sugar alcohol particles. This effectively avoids the problem of sugar alcohol particles settling at the bottom or deviating from the core stirring area in traditional stirring, and significantly improves the mixing efficiency.

[0035] See Figure 1 , Figure 2 , Figure 3 and Figure 4The shaking mechanism 2 includes a rotating table 21, on which a U-shaped frame 23 is connected via a moving component 22. A tilting frame 24 is rotatably mounted on the U-shaped frame 23. The tilting frame 24 is fixedly connected to the mixing vessel 1 and is used to repeatedly tilt the mixing vessel 1. The moving component 22 moves the mixing vessel 1 repeatedly in various directions, so that the sugar alcohol particles intermittently pass the axis position of the mixing vessel 1 under the action of inertia, thereby forcing the stirring paddle 31 to contact the sugar alcohol particles.

[0036] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The stirring mechanism 3 includes two stirring paddles 31 symmetrically arranged in the stirring vessel 1. Two hydraulic cylinders 241 are fixedly installed on the tilting frame 24. The upper ends of the telescopic sections of the two hydraulic cylinders 241 are fixedly connected to end caps 242 for sealing and fitting the stirring vessel 1. The two stirring paddles 31 are rotatably connected to the stirring vessel 1 and the end caps 242 respectively, and the two stirring paddles 31 are located on both sides of the waist of the stirring vessel 1. Excitation motors 32 for driving the stirring paddles 31 are fixedly connected to the stirring vessel 1 and the end caps 242.

[0037] When it is necessary to mix sugar alcohol particles with solvent to form a sugar alcohol solution, firstly, the telescopic sections of the two hydraulic cylinders 241 extend simultaneously to move the end cap 242 upward, so that the end cap 242 is away from the opening of the mixing vessel 1. Then, the operator adds the prepared sugar alcohol particles and solvent into the mixing vessel 1. Afterward, the telescopic section of the hydraulic cylinder 241 is retracted, so that the end cap 242 is sealed and fitted into the mixing vessel 1, thereby forming a closed space inside the mixing vessel 1.

[0038] Two excitation motors 32 are started to drive two agitators 31 to rotate at high speed, so that the agitators 31 begin to mix the sugar alcohol particles with the solvent. At the same time, when the blades of the high-speed rotating agitators 31 come into contact with the sugar alcohol particles, they form a shearing action, further breaking up the sugar alcohol particles and accelerating the mixing of sugar alcohol particles and solvent.

[0039] It should be noted that in this embodiment, the stirring paddle 31 is composed of a shaft and blades, and the end cover 242 is rotatably connected to the corresponding shaft in a sealed manner. Similarly, the stirring vessel 1 is rotatably connected to the corresponding shaft in a sealed manner.

[0040] During mixing, the tilting frame 24 rotates intermittently by half a revolution, causing the tilting frame 24 to drive the stirring vessel 1 to reciprocate. This causes the sugar alcohol particles in the stirring vessel 1 to intermittently pass through the waist of the stirring vessel 1 under the action of gravity. Utilizing the aggregation capacity formed by the structure of the hourglass-shaped stirring vessel 1 with a small diameter at the waist and a large diameter at both ends, the sugar alcohol particles are forced to gather in the middle of the stirring vessel 1 and come into contact with the stirring paddle 31, thereby increasing the contact opportunity between the sugar alcohol particles and the stirring paddle 31 and improving the mixing efficiency.

[0041] To facilitate the rotation of the tilting frame 24, the present invention is designed with the following structure: (See attached diagram) Figure 1 , Figure 2 , Figure 3 and Figure 5 A geared motor 231 is fixedly installed on the U-shaped frame 23. The output shaft of the geared motor 231 is fixedly connected to the rotating shaft of the tilting frame 24. By starting the geared motor 231, the tilting frame 24 is driven to rotate, thereby causing the stirring vessel 1 to be tilted back and forth. The stirring vessel 1 is not tilted continuously, but after each tilt, a period of time is waited so that the sugar alcohol particles that have rotated to the top of the stirring vessel 1 can fall completely during this period of time. This waiting time is obtained by repeated experiments by those skilled in the art.

[0042] To facilitate linear reciprocating movement of the stirring vessel 1 in all directions, the present invention designs the following structure: (See attached diagram) Figure 1 , Figure 2 , Figure 4 and Figure 5 The moving component 22 includes a guide rail disk 221 fixedly mounted on a rotary table 21. A movable disk 222 is slidably disposed on the upper side of the guide rail disk 221 along its radial direction. The upper side of the movable disk 222 is rotatably connected to the U-shaped frame 23. Two symmetrically arranged hydraulic cylinders 224 are fixedly mounted on the guide rail disk 221. The output shafts of the two hydraulic cylinders 224 are fixedly connected to the movable disk 222.

[0043] When the mixing vessel 1 needs to be moved linearly, the telescopic section of one hydraulic cylinder 224 extends, while the telescopic section of the other hydraulic cylinder 224 retracts synchronously. This causes the two hydraulic cylinders 224 to jointly drive the moving disk 222 to move radially along the guide disk 221. The moving disk 222 then drives the mixing vessel 1 to move synchronously. Because the mixing vessel 1 moves relatively quickly, the sugar alcohol particles inside the mixing vessel 1 maintain their position under inertia, thereby causing the mixing vessel 1 and the sugar alcohol particles to move relative to each other. This allows the sugar alcohol particles to pass through the axial position of the mixing vessel 1, further forcing the stirring paddle 31 to contact the sugar alcohol particles.

[0044] It is worth noting that the timing of the linear movement of the stirred tank 1 was determined through repeated experiments by those skilled in the art. This ensures that when most of the sugar alcohol particles fall to the position of the upper stirring paddle 31, they undergo a linear movement once. Then, when most of the sugar alcohol particles fall to the position of the lower stirring paddle 31, they undergo a second linear movement, thus completing one reciprocating movement of the stirred tank 1. After that, the stirred tank 1 is inverted, and then the stirred tank 1 undergoes linear movement again.

[0045] In order to enable the stirred tank 1 to move in multiple linear directions, so that the sugar alcohol particles acquire inertial action in multiple directions, and change the trajectory of the sugar alcohol particles that are only subject to gravity or centrifugal force in one direction, and further enhance the contact opportunity between the stirring paddle 31 and the sugar alcohol particles, the present invention designs the following structure: (Continue reading) Figure 1 , Figure 2 , Figure 4 and Figure 5 A synchronous motor 223 is fixedly installed on the U-shaped frame 23, and the output shaft of the synchronous motor 223 is fixedly connected to the moving disk 222.

[0046] After the mixing vessel 1 completes one reciprocating linear movement, the synchronous motor 223 is started and rotates synchronously in the opposite direction with the rotary table 21. The rotary table 21 drives the moving disk 222 to rotate in the forward direction through the guide plate 221. At the same time, the synchronous motor 223 drives the moving disk 222 to rotate in the opposite direction at the same speed, so that the U-shaped frame 23 maintains its angle without rotating. When the angle of the guide plate 221 deflects, the mixing vessel 1 is moved again, that is, it moves along the straight trajectory after the deflection.

[0047] In this embodiment, each time the stirring vessel 1 completes one reciprocating linear movement, the guide rail disk 221 is rotated ninety degrees. For example, when the stirring vessel 1 completes a back-and-forth reciprocating movement, the stirring vessel 1 will then perform a left-right reciprocating movement. After the stirring vessel 1 completes two reciprocating linear movements, the guide rail disk 221 is rotated sixty degrees to prevent the stirring vessel 1 from moving in the same direction as the first movement. The above steps are repeated to ensure that the stirring vessel 1 can move linearly in several directions.

[0048] To enhance the contact time between the sugar alcohol particles flung to the conical inner wall of the stirred tank 1 and the stirring paddle 31 by centrifugal force, thereby further increasing the contact opportunities between the sugar alcohol particles and the stirring paddle 31 and improving the stirring efficiency, the present invention designs the following structure: (See attached diagram) Figure 3 Both sides of the conical inner wall of the mixing vessel 1 are fixed with circumferentially distributed spiral protrusions 11. During mixing, the sugar alcohol particles fall along the trajectory of the spiral protrusions 11 under the centrifugal swing of the stirring paddle 31.

[0049] The spiral boss 11 guides the sugar alcohol particles attached to the wall, causing these sugar alcohol particles to fall slowly along the trajectory of the spiral boss 11 by gravity. Compared with the direct vertical fall of sugar alcohol particles, this prolongs the fall time of sugar alcohol particles on the wall of the stirred tank 1, increases the contact time and contact frequency between sugar alcohol particles and stirring paddle 31, and further improves the shearing and mixing effect of stirring paddle 31 on sugar alcohol particles.

[0050] After the sugar alcohol solution is prepared, let it stand for 30 seconds, open the end cap 242, and use a clean pipette to draw an equal volume of solution from below the liquid surface in the middle of the stirred tank 1 at a uniform speed. Transfer the solution one by one into six pre-dried and constant-weight glass sample containers, and label them as S1 to S6. Inject about 5 ml of solution into each sample container and immediately seal it to prevent moisture evaporation or moisture absorption.

[0051] These sample containers were then immediately sent to a differential refractive index detector (DRPD) to detect the purity of sugar alcohols in the sample containers using high performance liquid chromatography (HPLC). During the detection process, the chromatographic peak area of ​​each sample was recorded, and the percentage content of sugar alcohols in each sample was calculated using the external standard method with standard sugar alcohol references. The DPD is a general-purpose concentration detector used in liquid chromatography systems and is an existing technology.

[0052] The method for determining the purity of sugar alcohols is as follows: Calculate the arithmetic mean of the sugar alcohol purity values ​​in six sample containers. If the average value is ≥99.5%, the sugar alcohol purity of the batch is deemed to be qualified; if the average value is <99.5%, the sugar alcohol purity of the batch is deemed to be unqualified.

[0053] Although this invention adds structures such as a rotary table 21, a U-shaped frame 23, and a tilting frame 24 to the traditional mixing equipment, and adopts an hourglass-shaped stirring vessel 1 and a double stirring paddle 31 configuration, it slightly increases the initial investment cost and structural complexity compared to ordinary stirring devices. However, this invention can force the sugar alcohol particles to fully contact the stirring paddle 31 by reciprocating inversion and linear reciprocating movement of the stirring vessel 1 in various directions. This effectively avoids the technical problems of sugar alcohol particles settling at the bottom or deviating from the core stirring area and accumulating on the wall surface in traditional equipment. Thus, it can efficiently and uniformly complete the mixing of sugar alcohol particles and solvent in a short time, providing a high-quality test solution for subsequent high-performance liquid chromatography (HPLC) detection of sugar alcohol purity. Therefore, this invention significantly improves the pretreatment efficiency and detection accuracy of sugar alcohol purity detection. The resulting improvement in detection accuracy and time cost savings are sufficient to offset the initial equipment investment, making it highly practical and economical.
