A molding auxiliary device based on microcapsule granulation and a molding process thereof

Abstract

The present invention discloses a molding auxiliary equipment based on microcapsule granulation and a molding process thereof, which relates to the field of microcapsule molding technology. The equipment comprises a machine base, wherein an extruder is fixedly connected to the top of the machine base, an arch is fixedly connected to the bottom surface of the machine base, and a DC high-voltage power supply is fixedly connected to the inner wall of the bottom of the machine base. Through the setting of a hydraulic stirring mechanism, an inclined tube is used to stir the solidified phase liquid in a turbulent manner without interfering with the charge magnetic field of the DC high-voltage power supply. At the same time, compared with traditional stirring, under the action of hydraulic pressure, when the inclined tube rotates, the pressure at its top outlet is small and the liquid flow rate is fast, while the pressure at the bottom water inlet is large and the flow rate is slow, so that the liquid at the bottom center of the gel bathtub is continuously sucked in and then discharged from the top, forming a turbulent cycle. When the droplets continuously fall to the solidified phase stirring center, they can be pushed toward the edge of the gel bathtub by the force of the liquid rotation and turbulence, effectively preventing the droplets that have not yet solidified from sticking to each other, thereby improving the quality of the microcapsules and the uniformity of the shape.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of microcapsule forming, in particular to a forming auxiliary equipment based on microcapsule granulation and a forming process thereof. BACKGROUND

[0002] Microcapsules are small particles surrounded by a coating or shell containing active ingredients or core materials, and the forming process mainly includes material preparation, glue preparation, wrapping operation, curing and subsequent processing, etc. Among them, the wrapping material is an important condition for determining the solubility and storage of the core material, so it needs to be continuously experimented and explored to prepare microcapsule products with different properties and purposes.

[0003] In the prior art, the wrapping material and the active ingredient are usually mixed in liquid form, and then added dropwise into the curing phase in stirring. The commonly used stirring method in the laboratory is magnetic stirring, which can fully mix the components of small volume of liquid and achieve the required uniformity. However, in the microcapsule forming experiment, the liquid droplets need to be adsorbed by electric charge, and the magnetic field generated by the magnetic stirrer during work may interfere with the adsorption and separation process of the electric charge, resulting in uneven formation or irregular shape of the microcapsules. In addition, the disturbance caused by stirring may also cause the liquid droplets to deform or break during the dropping process, thereby affecting the quality and shape of the microcapsules.

[0004] In addition, during the curing process, the gel particles in the culture dish will accumulate more and more. In order to avoid excessive shear force that may damage the stability of the curing phase, the stirring intensity is usually not too large. Therefore, the particles often contact with each other, which makes the contact between the gel particles and the curing phase insufficient, thereby increasing the curing time and affecting the experimental progress.

[0005] Therefore, in view of the above problems, the present application provides a forming auxiliary equipment based on microcapsule granulation and a forming process thereof to overcome the shortcomings of the prior art. SUMMARY

[0014] As preferred, the vibration auxiliary mechanism further comprises a plurality of limiting rods equidistantly fixedly connected to the bottom of the gel bath basin, a shock-absorbing pad slidingly sleeved to the outer wall of the middle of the limiting rods, the bottom of the limiting rods slidingly connected to the inner wall of the machine base, the bottom of the shock-absorbing pad fixedly connected to the outer wall of the machine base, and the top of the shock-absorbing pad and the bottom of the gel bath basin abutted to each other.

[0016] As preferred, the inclined pipe, the straight pipe and the water inlets are arranged in communication with each other.

[0017] As preferred, the bottom of the mesh basin is inclined, and the baffle is annularly arranged.

[0018] A forming process based on microcapsule granulation, comprising the following steps:

[0019] Step one: material preparation and glue preparation: first prepare the wrapping material of polysaccharide, and prepare the active ingredient to be wrapped, then dissolve the wrapping material in the appropriate solvent respectively, stir uniformly, and prepare different numbered glue;

[0020] Step two: wrapping operation: add the active ingredient into different glue liquids in sequence, stir and mix uniformly, then pour the glue liquids of different numbers into the extruder in sequence, because the needle of the extruder is applied with voltage, the glue liquid inside is affected by surface tension and electric field force, and is pushed by external force, the liquid will be broken, shrink under the action of surface tension, and then drop into the solidification phase liquid below the arch, so that the micro gel particles are formed;

[0021] Step three: solidification and post-processing: pre-select the solidifying agent suitable for different wrapping materials, and use the machine base to create good solidification conditions for the solidification process, ensure the stability and performance of the microcapsule, perform a control experiment to select the optimal glue combination, by placing the wrapped droplets in the solidifying agent, so that they are further solidified into stable microcapsules, then, the solidified microcapsules are washed, dried to remove residual solvents, finally, the microcapsules are screened and graded to obtain the required microcapsule products;

[0022] Step four: comparison results: compare the predicted three results of adding acrylic acid / allyl methacrylate copolymer AMP salt and not adding such copolymer, first, the addition of the copolymer can make the microbead shape more regular and the surface more smooth, second, after adding the copolymer, under the same voltage, liquid flow rate and polysaccharide concentration, the microspheres are smaller, third, the introduction of the copolymer will slow down the release of the wrapped material, then, after predicting the conclusion, an experiment manual is formed, and the solidified microcapsules are reserved.

[0023] Compared with the prior art, the beneficial effects of the present application are:

[0024] 1. In the microcapsule granulation experiment, the hydraulic stirring mechanism is set up to use an inclined tube to stir the solidified phase liquid in a turbulent manner, without interfering with the charge magnetic field of the DC high-voltage power supply. At the same time, compared with traditional stirring, under the action of hydraulic pressure, when the inclined tube rotates, the pressure at the top outlet is small and the liquid flow rate is fast, while the pressure at the bottom inlet is high and the flow rate is slow, so that the liquid at the bottom center of the gel bath is continuously sucked in and then discharged from the top, forming a turbulent cycle. The stirring speed should be moderate to avoid excessive shear force that destroys the stability of the solidified phase. At the same time, when the droplets continuously fall into the center of the solidified phase stirring, they can be pushed toward the edge of the gel bath by the force of the liquid rotation and turbulence, effectively preventing the unsolidified droplets from sticking to each other, thereby improving the quality and shape uniformity of the microcapsules;

[0025] 2. After the droplets solidify to form gel particles, the gel particles are filtered out from the solidified phase through the setting of the strainer basin. Since the bottom of the strainer basin is set at an angle, and the inclination angle of the bottom of the strainer basin is set from high to low from far away from the guide plate to close to the guide plate, the gel particles can roll out from the discharge port along the slope of the bottom of the strainer basin, which is convenient for discharge;

[0026] The first and second leak holes are arranged perpendicular to each other, allowing the gel particles at the second leak hole to roll faster along the hole groove to prevent accumulation. When the gel particles reach the first leak hole, the liquid adhering to the outer wall of the gel particles can be intercepted laterally by the first leak hole, thereby weakening the mutual adsorption of the gel particles, making it easier for them to pass through the discharge port. This also reduces the loss of solidified phase liquid, allowing the liquid in the gel bath to be reused.

[0027] 3. Through the setting of the vibration auxiliary mechanism, while the shaft rotates, the extrusion block can continuously squeeze the arc block, so that the gel bath, the colander and the solidified phase in the gel bath all vibrate slightly. As a result, during the curing process, the vibrating solidified phase can disperse the mutual distance between the gel particles, so that the solidified phase can fully wrap the particles and reduce the curing time. During the discharging process, the vibration of the colander can assist in the full discharge of the gel particles, and cooperate with the external feeder to automatically fill the material at the extruder to continuously manufacture microbeads, so that the preparation of microbeads and quantitative discharging are carried out continuously, avoiding the interruption of the experiment to collect microbeads in the existing technology, and also preventing the residual gel particles from mixing with the next batch of gel, affecting the accuracy of the experiment, and ultimately improving the overall experimental rate.

[0048] A hydraulic stirring mechanism 5 is used to stir and quickly discharge the solidified phase by liquid pressure;

[0049] A vibration auxiliary mechanism 6 is used to continuously prepare microbeads and automatically continuously discharge the microbeads;

[0050] The hydraulic stirring mechanism 5 comprises a servo motor 54 fixedly connected to the inner wall of the base 1, a rotating shaft 513 fixedly connected to the top of the servo motor 54, a gel bath 51 rotatably penetrating through the top of the rotating shaft 513, the rotating shaft 513 extending to the bottom of the inner cavity of the gel bath 51 at the top, a main gear 512 fixedly connected to the end of the rotating shaft 513 away from the servo motor 54, a secondary gear 511 meshingly connected to the outer wall of the main gear 512, an inclined pipe 55 fixedly connected to the top of the secondary gear 511, a straight pipe 515 rotatably connected to the bottom of the secondary gear 511, the straight pipe 515 being fixedly connected to the inner wall of the gel bath 51 at the bottom, and a plurality of water inlets 514 being equidistantly arranged on the bottom of the straight pipe 515 around the circumference;

[0052] The hydraulic stirring mechanism 5 further comprises a discharge port 57 formed in the side wall of the mesh basin 52, the discharge port 57 is formed close to one side of the guide plate 53, a plurality of first leakage holes 58 are formed in the bottom of the mesh basin 52 close to one side of the discharge port 57, a plurality of second leakage holes 59 are formed in the bottom of the mesh basin 52 away from the discharge port 57, and the first leakage holes 58 and the second leakage holes 59 are arranged perpendicular to each other;

[0053] The inclined pipe 55, the straight pipe 515 and the water inlet 514 are arranged in communication with each other;

[0054] The bottom of the mesh basin 52 is arranged to be inclined, and the baffle 510 is arranged in a ring shape;

[0056] The effects achieved by the embodiment are as follows: in the prior art, the magnetic stirrer generates a magnetic field when working, which may interfere with the adsorption and separation process of electric charges, leading to uneven formation or irregular shape of the microcapsules, and the disturbance generated by stirring may also cause the droplets to deform or break during the falling process, thereby affecting the quality and shape of the microcapsules. Compared with the prior art, by implementing the embodiment, the hydraulic stirring mechanism 5 can use the inclined pipe 55 to stir the solidification phase liquid, without interfering with the electric charge magnetic field of the direct current high voltage power supply 4, and compared with the traditional stirring, under the action of the hydraulic pressure, the liquid at the center of the bottom of the gel bath basin 51 is continuously sucked in and discharged from the top, forming a rolling circulation. When the droplets continuously fall to the center of the solidification phase stirring, they can be pushed to move in the direction of the edge of the gel bath basin 51 by the rotating rolling force of the liquid, effectively preventing the mutual adhesion of the droplets that have not yet solidified.

[0057] Further embodiments: please refer to Figure 2 、 Figure 6 、 Figure 7 、 Figure 9 、 Figure 10 as shown:

[0059] The vibration auxiliary mechanism 6 further comprises a plurality of limiting rods 62 fixedly connected to the bottom of the gel bath 51 at equal intervals, a shock pad 61 is slidably sleeved to the outer wall of the middle portion of the limiting rod 62, the bottom of the limiting rod 62 is slidably connected to the inner wall of the machine base 1, the bottom of the shock pad 61 is fixedly connected to the outer wall of the machine base 1, and the top of the shock pad 61 abuts against the bottom of the gel bath 51.

[0060] The shock pad 61 is arranged in a ring shape.

[0061] The inner diameter of the shock pad 61 is greater than the outer diameter of the pair of arc blocks 63, so as to avoid movement obstruction.

[0062] The effects achieved by the embodiment are as follows: in the prior art, the stirring intensity is usually not too large, so the particles often contact each other, so that the contact between the gel particles and the solidified phase is not sufficient enough, thereby increasing the solidification time and affecting the experimental progress. Compared with the prior art, by implementing the embodiment, the vibration auxiliary mechanism 6 can make the extrusion block 66 continuously extrude the arc block 63 while the rotating shaft 513 rotates, so as to achieve the purpose that the gel bath 51, the meshed basket 52 and the solidified phase in the gel bath 51 all vibrate slightly, thereby making the vibrating solidified phase disperse the mutual distance between the gel particles during the solidification process, and reducing the solidification time.

[0063] Embodiment two of the present application

[0064] A molding process based on microcapsule granulation, comprising the following steps:

[0065] Step one: material preparation and glue preparation: first prepare the wrapping material of polysaccharide, and prepare the active ingredient to be wrapped, then dissolve the wrapping material in the appropriate solvent respectively, stir uniformly, and prepare different numbered glue;

[0066] Step two: wrapping operation: add the active ingredient into different glue in sequence, stir and mix uniformly, then pour the glue of different numbers into the extruder 2 in sequence, because the needle of the extruder 2 is applied with voltage, the glue inside is affected by surface tension and electric field force, and the liquid will break under the action of surface tension and external force, then drop into the solidified phase liquid under the arch 3, so as to form small gel particles;

[0067] Step three: solidification and post-processing: pre-select the solidifying agent suitable for different wrapping materials, and use the machine base 1 to create good solidification conditions for the solidification process, to ensure the stability and performance of the microcapsule, and select the optimal glue combination through a control experiment, then, let the wrapped droplets stand in the solidifying agent to further solidify into stable microcapsules, then, wash, dry and process the solidified microcapsules to remove residual solvents, finally, screen and grade the microcapsules to obtain the required microcapsule products.

[0068] Step four: comparison results: comparison of adding acrylic ester / allyl methacrylate copolymer AMP salt and not adding such copolymer, the predicted three results, first, the addition of copolymer can make the shape of the microbead more regular, the surface is smoother, second, after adding the copolymer, under the same voltage, liquid flow rate, polysaccharide concentration, respectively, make the microsphere smaller, third, the introduction of copolymer will slow down the release of its wrapped material, then, after the predicted conclusion is formed into an experimental manual, then the solidified microcapsule sample is left;

[0076] The complete use steps and working principle of the above embodiment are as follows:

[0077] Initial state: the mesh basin 52 is contracted in the inside of the gel bath basin 51, the gel bath basin 51 is attached to the shock pad 61, the extrusion block 66 and the circular arc block 63 are in the non-abutting state, and the servo motor 54 is in the closed state.

[0078] Working process:

[0079] In use, the experimenter first prepares the solidification phase solution of the gel bath 51, then starts the servo motor 54 to drive the rotating shaft 513 to rotate, which synchronously drives the main gear 512 to rotate, and the main gear 512 can continue to drive the secondary gear 511 to rotate, so that the inclined pipe 55 at the top of the secondary gear 511 also rotates. Since the inclined pipe 55 is inclined and communicates with the straight pipe 515 and the water inlet 514, under the action of the pressure of the solidification phase liquid, the rotation of the inclined pipe 55 can push the solidification phase to flow faster, so that the outlet pressure at the top of the inclined pipe 55 is small, the liquid flow rate is fast, the pressure at the bottom of the water inlet 514 is large, and the liquid flow rate is slow, so that the solidification phase liquid in the gel bath 51 continuously enters the straight pipe 515 from the bottom water inlet 514 and is adsorbed by the pressure in the inclined pipe 55 and discharged from the top, circulating and flowing, and cooperating with the continuous rotation and stirring of the inclined pipe 55 to achieve the purpose of central upwelling and stirring of the solidification phase. In this way, when the liquid droplets extruded by the extruder 2 fall to the stirring center, they can be pushed by the rotating upwelling force of the liquid to move in the direction of the edge of the gel bath 51, which not only optimizes the traditional magnetic stirring method, but also ensures that the liquid droplets that have not solidified will not stick together when continuous dripping, thereby improving the quality of the microcapsules;

[0080] Further, when the gel droplets are finished and the gel particles in the gel bath 51 have been solidified, the experimenter can hold the convex plate 56 with both hands and move the mesh basin 52 upward from the inner wall of the gel bath 51, so that the gel particles are filtered out from the solidification phase, and the solidification phase liquid flows down from the pores of the mesh basin 52 and can be recycled in the gel bath 51. Since the bottom of the mesh basin 52 is inclined and the inclination angle of the bottom of the mesh basin 52 from the guide plate 53 to the guide plate 53 is set from high to low, the gel particles can roll out from the discharge port 57 along the slope of the bottom of the mesh basin 52 and be discharged through the guide plate 53 for the next step. The first drain hole 58 and the second drain hole 59 arranged perpendicularly can assist the discharge of the gel particles. The gel particles at the second drain hole 59 can accelerate rolling along the hole groove direction, and when they reach the first drain hole 58, the liquid adhered to the outer wall of the gel particles can be intercepted by the first drain hole 58 horizontally, thereby reducing the mutual adsorption of the gel particles and making them easier to pass through the discharge port 57, while also reducing the loss of the solidification phase liquid;

[0081] The above working process is described in detail in Figures 1 to 6 、 Figure 8 .

[0082] Further, when the rotating shaft 513 rotates, the connecting rod 67 also rotates, and the connecting rod 67 synchronously drives the extrusion block 66 to slide at the bottom of the gel bath basin 51, and the stability is ensured by the sliding support of the bottom roller 65 of the extrusion block 66 in the ring groove 64. Whenever the extrusion block 66 reaches the position of the circular arc block 63, the extrusion block 66 extrudes the circular arc block 63, and the gel bath basin 51 is stably lifted and slightly displaced by a pair of circular arc blocks 63, and then falls down. When the gel bath basin 51 falls down, the bottom of the gel bath basin 51 is in contact with the shock pad 61, the gel bath basin 51 is buffered by the elastic force of the shock pad 61, and the gel bath basin 51 is always limited by the limiting rod 62. Through the above-mentioned reciprocating process, when the rotating shaft 513 rotates, the gel bath basin 51 is shaken as a whole, so that the gel bath basin 51, the mesh basin 52 and the solidified phase in the gel bath basin 51 are slightly vibrated. Therefore, during the solidification process, the vibration of the solidified phase can disperse the mutual distance of the gel particles, so that the solidified phase fully wraps the particles, reduces the solidification time, and in the discharging process, the vibration of the mesh basin 52 can assist the full discharge of the gel particles, prevent the residual gel particles from mixing with the next batch of gel, and affect the accuracy of the experiment. The external feeder is matched to automatically fill the material at the extruder, continuously manufacture the microbeads, and form the preparation of the microbeads and the continuous quantitative discharging, so that the experimental efficiency is improved.

[0083] The above working process please refer to Figure 2 、 Figure 6 、 Figure 7 、 Figure 9 、 Figure 10 .

[0085] Although embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.

8. A molding process based on microcapsule granulation, applied to a molding auxiliary device based on microcapsule granulation according to any one of claims 1 to 7, characterized in that: The following steps are involved: Step 1: Material preparation and glue preparation: First, prepare the polysaccharide encapsulation material and the active ingredient to be encapsulated. Then, dissolve the encapsulation materials in a suitable solvent, stir evenly, and prepare glues of different numbers; Step 2: Encapsulation operation: The active ingredients are sequentially added to different glue solutions, stirred and mixed evenly, and then the glue solutions with different numbers are sequentially put into the extruder (2). Since the needle of the extruder (2) is subjected to voltage, the glue solution inside is affected by surface tension and electric field force, and the external force pushes the glue solution, causing the liquid to break and shrink under the action of surface tension. The liquid solution is then dripped into the solidified phase liquid below the arch (3), forming tiny gel particles. Step 3: Curing and post-processing: Preselect a curing agent suitable for different packaging materials, and use a machine base (1) to create good curing conditions for the curing process to ensure the stability and performance of the microcapsules. Conduct a control experiment to select the optimal glue combination. Place the wrapped droplets in the curing agent to further solidify them into stable microcapsules. Then, wash and dry the cured microcapsules to remove residual solvents. Finally, screen and grade the microcapsules to obtain microcapsule products that meet the requirements. Step 4: Comparison of results: Comparison of the presence and absence of acrylate / allyl methacrylate copolymer AMP salt in the adhesive solution. The three predicted results are: first, the addition of the copolymer can make the microbeads more regular in shape and smoother in surface; second, the addition of the copolymer can make the microspheres smaller at the same voltage, liquid flow rate, and polysaccharide concentration; third, the introduction of the copolymer will slow down the release of its encapsulated substances; then, the predicted conclusions are drawn up and an experimental manual is formed, and samples of the cured microcapsules are retained.
