Description

Technical Field

[0001] This invention relates to the field of chemical technology, and in particular to a swing-type sucrose-6-ester production apparatus and its production method. Background Technology

[0002] Sucrose-6-ester is an important intermediate in the synthesis of the artificial sweetener sucralose. One method for synthesizing sucrose-6-ester includes: mixing sucrose, an aprotic polar solvent, and an organotin acylation promoter to form a first reaction mixture; then contacting the first reaction mixture with a gas or solvent vapor capable of removing water under specific temperature and pressure conditions and maintaining the reaction for a certain time to remove water, thereby obtaining a second reaction mixture; then adding carboxylic anhydride to the second reactants to obtain a third reaction mixture, and maintaining the third reaction mixture at a temperature sufficient to prepare sucrose-6-ester. This method requires the use of a gas or solvent vapor capable of removing water, and this step significantly affects the continuity of the sucrose-6-ester synthesis process, increases production time, and reduces production efficiency.

[0003] Therefore, a dedicated apparatus and production method for the preparation of sucrose-6-ester is needed to overcome the shortcomings of using water-removing gases or solvent vapors in the first reaction mixture to remove water during the water removal process.

[0004] Therefore, based on the above, and drawing on years of experience in design, development and actual production in the relevant industry, the inventor has researched and improved the existing structure and its shortcomings, and provides a swing-type sucrose-6-ester production device and its production method, in order to achieve a more practical purpose.

[0016] A method for producing sucrose-6-ester using a swing-type sucrose-6-ester production apparatus includes the following steps:

[0017] S1: The workpiece is intermittently fed into the sub-component through the feed inlet;

[0018] S2: When the slide rod is moved within the annular slide rail by the eccentric plate and motor, the tilt angle of the connecting plate and the slide rod causes the slide rod to press the swaying component to sway circumferentially along the bottom ball shaft, causing the sub-component to sway circumferentially within the arc-shaped channel. When the sub-component shifts to the lowest point, it contacts the inner wall of the arc-shaped channel, causing some of the processed material to flow down along the gap wall between the sub-component and the arc-shaped channel, forming a thin liquid film. The sub-component is internally heated, so the processed material is continuously heated inside the sub-component as it falls from the feed inlet. The airflow generated by the swaying of the sub-component and the up-and-down movement of the receiving plate forces the steam to surge towards the condenser, accelerating the separation of the steam in the processed material. The steam is then drawn into the condenser below the ball shaft and discharged outside the main body of the device. At the same time, since the side of the arc-shaped channel near the center is open, as the processed material continuously slides down the wall of the arc-shaped channel, it is continuously cooled by the low-temperature space formed by the condenser, creating a temperature conducive to the fusion with carboxylic anhydride.

[0019] S3: When the workpiece flows along the inner wall of the arc-shaped channel to the receiving plate, the outer diameter of the receiving plate and the arc-shaped channel have a certain gap, and the upper part of the receiving plate is conical, which prolongs the dwell time of the workpiece.

[0020] S4: Carboxylic anhydride is placed in a mixing tank and mixed by the shaking of a mixing rod and a mixing ball. The mixed product flows out from the discharge port.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] The component moves in a circular motion within the arc-shaped channel, and when the component shifts to its lowest point, it contacts the inner wall of the arc-shaped channel, causing some of the processed material to flow down along the gap wall between the component and the arc-shaped channel, forming a thin liquid film.

[0023] The sub-components are internally heated, so that the workpiece is continuously heated inside the sub-component as it falls into the sub-component from the feed port. The airflow generated by the shaking of the sub-components and the up-and-down movement of the receiving plate forces the steam to surge towards the condenser, which accelerates the condensation and separation of the steam in the workpiece. The steam is then drawn into the condenser below the ball shaft and discharged outside the main body of the device.

[0024] Because the side of the arc-shaped channel closest to the center is open, as the processed material continuously slides down the wall of the arc-shaped channel, it is continuously cooled by the low-temperature space formed by the condenser, creating a temperature conducive to the fusion with the carboxylic anhydride. The up-and-down movement of the mixing sphere ensures that the reactants are fully mixed. Attached Figure Description

Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example 1

[0040] A swing-type sucrose-6-ester production device includes a main body 1, a motor 2, a swinging component 3, a condenser 4, and sub-components 5;

[0041] like Figure 1As shown, the top of the main body 1 of the device is provided with a feed inlet 11. There are five feed inlets 11 arranged in a star shape. The feed inlets 11 are intermittently fed. The motor 2 is provided in the middle of the top surface of the main body 1 of the device, and the discharge outlet 12 is provided at the bottom of the main body 1 of the device.

[0042] like Figure 2 As shown, the motor 2 has a rotating shaft 21 at its bottom, a connecting plate 22 at its bottom, an inclined eccentric plate 23 on the side of the connecting plate 22 away from the center of the rotating shaft 21, an inclined sliding rod 24 at the bottom of the eccentric plate 23, the bottom of the sliding rod 24 being placed in the annular slide rail 31 on the top surface of the swaying member 3, and being driven by the motor 2 to slide in the annular slide rail 31. A connecting rod 32 is provided on the outer circumferential surface of the swaying member 3. The number of connecting rods 32 is the same as the number of feed inlets 11 and the arrangement direction is also the same. Each connecting rod 32 has a sub-component 5 at its radial outer end. The sub-component 5 is arranged vertically and vertically with the feed inlet 11. The sub-component 5 is located in the arc-shaped channel 13 inside the main body 1 of the device. The arc-shaped channel 13 is a vertically opened guide channel for the processed material, and the inner diameter of the arc-shaped channel 13 is slightly larger than the diameter of the sub-component 5.

[0043] like Figure 3 As shown, the arc-shaped channels 13 are also arranged in a star shape, with the side closest to the center being an open arrangement;

[0044] like Figure 4 As shown, the bottom of the wobbling component 3 is provided with a spherical groove 33, which is sleeved on the bottom ball shaft 34 and can be tilted and offset along the outer wall of the ball shaft 34. When the slide rod 24 is driven by the eccentric plate 23 and the motor 2 to move within the annular slide rail 31, due to the tilt angle of the connecting plate 22 and the slide rod 24, the slide rod 24 presses the wobbling component 3 to make a circumferential wobbling along the bottom ball shaft 34. At the same time, the wobbling component 3 is connected to the sub-component 5, causing the sub-component 5 to make a circumferential wobbling within the arc-shaped channel 13. When the sub-component 5 is offset to the lowest point, it contacts the inner wall of the arc-shaped channel 13, so that part of the processing... The material flows down the gap wall between the sub-component 5 and the arc-shaped channel 13, forming a thin liquid film. The arc-shaped channel 13 is equipped with a heating element, which continuously heats the inside of the material as it falls into the sub-component 5 from the feed port 11. Due to the shaking, the vapor in the material is accelerated to separate and is drawn into the condenser 4 below the ball shaft 34 and discharged outside the main body 1 of the device. At the same time, since the side of the arc-shaped channel 13 near the center is open, as the material slides down the wall of the arc-shaped channel 13, it is continuously cooled by the low-temperature space formed by the condenser 4, forming a temperature that is conducive to the fusion with the carboxylic anhydride.

[0045] like Figure 5 As shown, since the structures of the multiple components 5 are the same and their locations have been explained, the structure of one component 5 will be described below.

[0046] like Figure 5 As shown, the bottom of the sub-component 5 is provided with a fixing rod 51, which is connected to the support rod 53 below through a universal joint 52. Two receiving plates 54 are provided on the support rod 53 at intervals. The outer diameter of the receiving plate 54 has a certain gap with the arc-shaped channel 13. The upper part of the receiving plate 54 is conical. The receiving plate 54 is used to extend the residence time of the processed workpiece, so that the processed workpiece can better dissipate hot steam and more effectively reduce the temperature, which is conducive to the mixing of carboxylic anhydride. At the same time, it provides a certain mixing time for the fusion space below. The bottom of the support rod 53 is inside the mixing tank 55. The mixing tank 55 is in the shape of an inverted truncated cone. The bottom surface of the mixing tank 55 is the fusion space and is provided with a carboxylic anhydride inlet.

[0047] like Figure 6 As shown, the bottom of the support rod 53 is provided with a scraper 56, which is used to further scrape off the processed material on the inner wall of the mixing tank 55 and accelerate the mixing with carboxylic anhydride. The bottom of the scraper 56 is provided with a mixing rod 57, and the bottom of the mixing rod 57 is provided with a mixing ball 571, so that the processed material and carboxylic anhydride are mixed more thoroughly.

[0048] like Figure 7 As shown, the sub-component 5 is hemispherical with an open top surface and an overflow hole 58 on its inner wall surface. The overflow hole 58 is used to drip the heated workpiece in small droplets.

[0049] This invention also provides a method for using equipment for the production of sucrose-6-ester:

[0050] S1: The workpiece is intermittently fed into the sub-component 5 through the feed inlet 11;

[0051] S2: When the slide rod 24 is moved within the annular slide rail 31 by the eccentric plate 23 and the motor 2, due to the tilt angle of the connecting plate 22 and the slide rod 24, the slide rod 24 presses the wobbling component 3 to wobble circumferentially along the bottom ball shaft 34, causing the sub-component 5 to wobble circumferentially within the arc-shaped channel 13. When the sub-component 5 shifts to its lowest point, it contacts the inner wall of the arc-shaped channel 13, causing some of the processed material to flow down along the gap wall between the sub-component 5 and the arc-shaped channel 13, forming a thin liquid film. Furthermore, the sub-component 5 is internally heated, allowing the processed material to flow down along the gap wall between the sub-component 5 and the arc-shaped channel 13. As the workpiece falls into the sub-component 5 from the feed inlet 11, it is continuously heated inside. Due to the shaking of the sub-component 5 and the up-and-down movement of the receiving plate 54, the airflow is generated, which forces the steam to surge towards the condenser 4, accelerating the separation of the steam in the workpiece. The steam is then drawn into the condenser 4 below the ball shaft 34 and discharged outside the main body 1 of the device. At the same time, since the side of the arc-shaped channel 13 near the center is open, as the workpiece continuously slides down the wall of the arc-shaped channel 13, it is continuously cooled by the low-temperature space formed by the condenser 4, creating a temperature that is conducive to the fusion with the carboxylic anhydride.

[0052] S3: When the workpiece flows along the inner wall of the arc-shaped channel 13 to the receiving plate 54, the outer diameter of the receiving plate 54 and the arc-shaped channel 13 have a certain gap, and the upper part of the receiving plate 54 is conical, which prolongs the dwell time of the workpiece.

[0053] S4: Carboxylic anhydride is placed in mixing tank 55 and mixed by the shaking of mixing rod 57 and mixing ball 571. The mixed processed product flows out from discharge port 12.

[0054] Example 2

[0055] The similarities to Example 1 will not be described again; the differences from Example 1 are as follows:

[0056] Please see Figure 8-10 In this embodiment, the bottom of the support rod 53 is disposed inside the mixing tank 55, and the mixing tank 55 is provided with a scraper 56. The support rod 53 is fixedly connected to the corresponding scraper 56. The scraper 56 is provided with a plurality of stirring holes 561 for stirring. The bottom of the mixing tank 55 is provided with a mixing box 59 fixedly connected. The mixing box 59 is provided with a mixing plate 591 slidably connected. The bottom of the support rod 53 moves through the mixing box 59, and the bottom of the support rod 53 is fixedly connected to the mixing plate 591. Multiple interconnected mixing pipes 532 are provided on the outside of the support rod 53 inside the mixing tank 55. Multiple spray holes 533 for material spraying are provided at the bottom of the mixing pipes 532. A guide channel 531 connected to the mixing pipes 532 is provided inside the support rod 53. A one-way drain valve 534 for unidirectional material conveying to the spray holes 533 is provided inside the guide channel 531. Multiple feed holes are provided on the mixing tank 59. A one-way water inlet valve 592 for unidirectional material entry is provided inside the feed holes.

[0057] The outer wall of the scraper 56 is slidably connected to the inner wall of the mixing tank 55. The support rod 53, due to the rotation of the eccentric plate 23, continuously performs periodic up-and-down reciprocating motion. This rotation of the support rod 53 drives the scraper 56 to move up and down within the mixing tank 55. The scraper 56 effectively scrapes away debris from the inner wall of the mixing tank 55, accelerating the mixing with the carboxylic anhydride. Simultaneously, the up-and-down movement of the scraper 56 causes a positional change in the material as it passes through the stirring hole 561, causing the material to be squeezed and ejected through the stirring hole 561. Thus, the stirring hole 561 effectively mixes the material... The materials in the mixing tank 55 are thoroughly mixed and homogeneous. At the same time, a mixing box 59 is set at the bottom of the mixing tank 55. The up and down movement of the support rod 53 drives the mixing plate 591 to move up and down periodically. Combined with the one-way drain valve 534 and the one-way water inlet valve 592, the mixing box 59 can form a suction "pump" to draw the materials at the bottom of the mixing tank 55 and transport them into the guide channel 531. The materials are then sprayed out through the spray holes 533 on the mixing pipe 532, so that the materials are more thoroughly mixed and homogeneous in the mixing tank 55, accelerating the mixing with carboxylic anhydride.

[0058] Please see Figure 8-10 In this embodiment, each of the mixing tanks 55 is provided with a discharge pipe 121 at the bottom. One end of the discharge pipe 121 is connected to the corresponding mixing box 59, and the other end of the discharge pipe 121 is connected to the discharge port 12. A first valve mechanism 124 that is fixedly connected and can be opened and closed is provided in the discharge pipe 121, and a second valve mechanism 535 that is slidably connected and can be opened and closed is provided in the guide groove 531.

[0059] The combination of the discharge pipe 121, the first valve mechanism 124, and the second valve mechanism 535 allows the material to be continuously circulated and mixed evenly within the mixing tank 55 during mixing. This is achieved by closing the first valve mechanism 124 and opening the second valve mechanism 535. After mixing is complete, the material can be discharged through the discharge pipe 121 by opening the first valve mechanism 124 and closing the second valve mechanism 535.

[0060] Please see Figure 8-10In this embodiment, the first valve mechanism 124 and the second valve mechanism 535 are the same type of mechanism. This mechanism includes a sealing plate 50 for sealing the corresponding channel. The sealing plate 50 is provided with a plurality of evenly distributed flow grooves 501. Each flow groove 501 is provided with a recovery groove 504 on the same side wall. The recovery groove 504 is provided with a slidably connected recovery plate 502. The sealing plate 50 is provided with a rotatingly connected adjusting shaft 503 in the middle. The adjusting shaft 503 is fixedly connected to the corresponding recovery plate 502. The adjusting shafts 503 of the first valve mechanism 124 and the second valve mechanism 535 are connected to and move synchronously. The discharge pipe 121 is also provided with a rotating shaft 123. The outer end of the rotating shaft 123 is provided with a fixedly connected rotating disk 122, and the end of the rotating shaft 123 is fixedly connected to the corresponding adjusting shaft 503.

[0061] The guide channel 531 is prismatic in shape, and the sealing plate 50 is slidably and sealingly connected to the guide channel 531. This design allows the second valve mechanism 535 to slide up and down within the guide channel 531 while the support rod 53 moves up and down. This ensures that the second valve mechanism 535 controls the opening and closing without affecting the up and down movement of the support rod 53. The design of the synchronous shaft 536, the flow channel 501, the adjusting shaft 503, the recovery channel 504, and the recovery plate 502 enables the first valve mechanism 124 and the second valve mechanism 535 to move synchronously through the transmission of the synchronous shaft 536. That is, when the synchronous shaft 536 opens the first valve mechanism 124, the second valve mechanism 535 automatically closes, and when the first valve mechanism 124 closes, the second valve mechanism 535 automatically opens, making the overall adjustment more convenient and faster. The design of the rotating disk 122 and the rotating shaft 123 enables the rotating disk 122 to drive the rotating shaft 123 to rotate, thereby causing the two adjusting shafts 503 to rotate synchronously, achieving selective opening and closing.

[0062] Please see Figure 8-10 In this embodiment, the synchronous shaft 536 is spiral-shaped, and a matching adjusting ring 594 is sleeved on the outside of the synchronous shaft 536. The bottom of each mixing plate 591 is provided with a positioning rod 5941 fixedly connected and used to drive the adjusting ring 594 to move synchronously. The bottom of the positioning rod 5941 is slidably connected to the adjusting ring 594. The outside of each adjusting ring 594 is provided with a stirring rod 593 fixedly connected.

[0063] The adjusting ring 594 has a convex-shaped limiting ring groove 5943, and a slidingly connected limiting ring plate 5942 is provided in the limiting ring groove 5943. The end of the positioning rod 5941 is fixedly connected to the limiting ring plate 5942. The spiral design of the synchronous shaft 536 allows the adjusting ring 594 to move synchronously up and down during the up and down movement of the mixing plate 591, through the positioning rod 5941. The sliding connection between the positioning rod 5941 and the adjusting ring 594, combined with the spiral design of the synchronous shaft 536, allows the adjusting ring 594 to rotate synchronously during its up and down movement. This causes the stirring rod 593 to move up and down in a spiral motion within the mixing chamber 59, ensuring that the materials within the mixing chamber 59 are thoroughly and evenly mixed.

[0064] Working principle:

[0065] (1) The carboxylic anhydride is fed into the mixing tank 55. As the support rod 53 moves back and forth periodically, the scraper 56 moves up and down periodically in the mixing tank 55. When the material passes through the stirring hole 561, it can be squeezed through, so that the stirring hole 561 on the scraper 56 can fully mix the material in the mixing tank 55 evenly.

[0066] (2) As the support rod 53 moves back and forth periodically, it drives the mixing plate 591 to move up and down periodically in the mixing box 59. At this time, the rotating disk 122 is rotated, causing the rotating shaft 123 to rotate, which drives the first valve mechanism 124 to close and the second valve mechanism 535 to open. Combined with the one-way drain valve 534 and the one-way water inlet valve 592, the mixing box 59 can form a suction "pump" to suck up the material at the bottom of the mixing barrel 55 and transport it to the guide groove 531. The material is then sprayed out through the spray hole 533 on the mixing pipe 532, so that the material is more thoroughly mixed in the mixing barrel 55 and the mixing with carboxylic anhydride is accelerated.

[0067] (3) While the mixing plate 591 moves back and forth periodically in the mixing box 59, it can drive the adjusting ring 594 to move up and down synchronously through the positioning rod 5941. The sliding connection between the positioning rod 5941 and the adjusting ring 594, plus the spiral design of the synchronous shaft 536, enables the adjusting ring 594 to rotate synchronously during the up and down movement, so that the stirring rod 593 can move up and down in a spiral motion in the mixing box 59 to stir, so that the material in the mixing box 59 can be fully and evenly mixed.

[0068] (4) After the materials are mixed, rotate the rotating disk 122 to open the first valve mechanism 124 and close the second valve mechanism 535. At this time, the materials are discharged through the discharge pipe 121 and transported to the discharge port 12.
