Description

Technical Field

[0001] This invention belongs to the field of pharmaceutical preparation detection technology, and specifically relates to a sampler for the preparation and detection of vitamin C microcapsules. Background Technology

[0002] Vitamin C, an essential water-soluble vitamin for the human body, has important physiological functions such as anti-oxidation and enhancing immunity, and is widely used in food additives, nutritional supplements and pharmaceutical preparations.

[0003] However, vitamin C is chemically unstable and easily decomposes and becomes ineffective due to factors such as light, heat, oxygen, and metal ions, severely limiting its effectiveness in practical applications. To improve the stability and bioavailability of vitamin C, microencapsulation technology has emerged. Microencapsulation involves encapsulating vitamin C in tiny capsules formed from polymeric materials, using physical barriers to protect the core substance from adverse environmental influences.

[0004] Currently, the industrial preparation of vitamin C microcapsules mainly employs processes such as spray drying, coagulation, and interfacial polymerization. Existing preparation equipment typically separates preparation and testing, requiring periodic shutdowns for sampling and testing during the preparation process. This is not only inefficient but also makes real-time quality control difficult due to the lag in testing. Traditional stirring devices often use simple paddle structures, resulting in limited mixing effects and the creation of dead zones that negatively impact microcapsule formation quality. Temperature control systems often lack precision, exhibiting significant temperature fluctuations that adversely affect the stability of vitamin C. Sampling devices are usually manually operated, leading to uneven sampling and a high risk of contamination. Utility Model Content

[0005] In view of this, the present invention provides a detection and acquisition device for the preparation of vitamin C microcapsules, which can solve the problem that the lack of real-time detection and acquisition methods in the preparation process of vitamin C microcapsules in the prior art leads to difficulty in controlling the preparation quality and poor product consistency.

[0006] This utility model is implemented as follows:

[0007] This invention provides a preparation and detection collection device for vitamin C microcapsules, comprising a preparation reactor, a detection and collection device, a support base, a transmission mechanism, and a temperature control system. The support base is a rectangular steel frame structure, with the preparation reactor fixedly installed at the center. The preparation reactor has a cylindrical structure and its axis is perpendicular to the plane of the support base. A feeding port is provided at the top of the preparation reactor, and a sealing cover is installed at the feeding port. The detection and collection device is installed on the side wall of the preparation reactor and includes a detection and collection device body, a rotating collection arm, and a collection pipeline. The detection and collection device body is cylindrical and fixed to the middle of the side wall of the preparation reactor via a flange connection. The rotating collection arm is rotatably installed inside the detection and collection body via a bearing assembly. One end of the rotating collection arm extends to the center of the inner cavity of the preparation reactor, and the other end is connected to the collection pipeline. The transmission mechanism is installed on one side of the support base and includes a drive motor and a reducer. The output shaft of the drive motor is connected to the input end of the reducer via a coupling, and the output end of the reducer is connected to the outer end of the rotating collection arm via a transmission shaft.

[0008] The technical advantages of the vitamin C microcapsule preparation detection and collection device provided by this utility model are as follows: Through the integrated design of the preparation reactor and the detection and collection device, real-time detection and collection during the vitamin C microcapsule preparation process are achieved, avoiding the time delay problem caused by traditional separate detection. The rotational movement of the collection arm inside the preparation reactor allows for sample collection at different positions, ensuring the representativeness and uniformity of the sampling. The transmission mechanism provides stable speed control through a reducer, ensuring the accuracy of the collection process, while the integrated design of the temperature control system provides a stable temperature environment for microcapsule preparation.

[0009] Based on the above technical solution, the vitamin C microcapsule preparation detection and collection device of this utility model can be further improved as follows:

[0010] The reactor has spiral stirring blades on its inner wall. The spiral stirring blades are spirally distributed along the inner wall of the reactor. The spiral angle of the spiral stirring blades is 30 to 60 degrees. The spiral stirring blades are fixed to the inner wall of the reactor by welding.

[0011] The beneficial effects of adopting the above-mentioned improved scheme are as follows: the design of the helical stirring blades can form a three-dimensional stirring flow field inside the preparation reactor, improving the mixing uniformity of vitamin C solution and encapsulation material. The helical angle, set within the range of 30 to 60 degrees, ensures sufficient stirring while avoiding excessive shearing that could damage the microcapsule structure. The distribution of the helical stirring blades along the inner wall effectively prevents the formation of dead zones, ensuring a uniform reaction throughout the entire system.

[0012] Furthermore, the detection and acquisition device also includes a filter screen and a buffer storage chamber. The filter screen is located at the front end of the rotating acquisition arm and has a conical stainless steel wire mesh structure with a mesh diameter of 50 to 100 micrometers. The buffer storage chamber is located inside the detection and acquisition body and is connected to the acquisition pipeline. The volume of the buffer storage chamber is 100 to 200 milliliters.

[0013] The beneficial effects of adopting the above-mentioned improved scheme are as follows: the conical design of the filter screen increases the filtration area and improves the filtration efficiency; at the same time, the mesh diameter of 50 to 100 micrometers can effectively separate microcapsule particles that meet the requirements. The buffer reservoir provides temporary storage space for sample collection, avoiding the impact of pressure fluctuations in the collection pipeline on sample quality. The 100 to 200 ml volume design meets the detection needs while avoiding sample retention problems caused by excessive volume.

[0014] Furthermore, the temperature control system includes a heating sleeve, a temperature sensor, and a temperature controller. The heating sleeve surrounds the outer wall of the preparation reactor and is fixed by a clamp. The heating sleeve contains a resistance wire heating element. The temperature sensor is installed on the side wall of the preparation reactor and its probe extends into the inner cavity of the preparation reactor. The temperature sensor is connected to the temperature controller via a cable.

[0015] The beneficial effects of the above-mentioned improved scheme are as follows: the design of the heating sleeve surrounding the outer wall of the reactor achieves uniform heating and avoids local overheating. The built-in design of the resistance wire heating element improves heat transfer efficiency and shortens heating time. The arrangement of the temperature sensor probe extending into the reactor cavity enables real-time monitoring of the actual temperature of the reaction system, and through linkage with the temperature controller, achieves precise temperature control, providing a reliable guarantee for the stable preparation of vitamin C microcapsules.

[0016] Furthermore, the rotating collection arm has an L-shaped structure, with the horizontal section being 2 / 3 the length of the inner diameter of the preparation reactor and the vertical section being 1 / 3 the height of the preparation reactor; the cross-section of the rotating collection arm is circular with a diameter of 8 mm to 12 mm.

[0017] The beneficial effects of adopting the above-mentioned improved scheme are as follows: The L-shaped rotating sampling arm design makes full use of the three-dimensional space inside the reactor, and the horizontal section length of 2 / 3 of the inner diameter ensures that the sampling range covers the main area of ​​the reactor. The vertical section length of 1 / 3 of the height allows for sampling at different liquid levels. The circular cross-sectional diameter of 8 mm to 12 mm ensures the structural strength of the sampling arm while reducing disturbance to the flow field of the reaction system and improving the representativeness of the collected samples.

[0018] Furthermore, the support base includes four support legs and a connecting beam. The four support legs are rectangularly distributed and bolted to the four corners of the connecting beam. Each support leg has a height-adjustable spiral adjustment foot at its bottom. The connecting beam is an I-beam structure with a circular mounting hole in the center. The preparation reactor is fixed in the circular mounting hole by a flange.

[0019] The beneficial effects of adopting the above-mentioned improved design are as follows: the rectangular distribution of the four support legs provides a stable support foundation, effectively resisting vibrations and torques generated during equipment operation. The height-adjustable spiral feet can adapt to different ground conditions, ensuring horizontal installation of the equipment. The connecting beams of the I-beam structure have high strength and rigidity, capable of bearing the weight of the preparation reactor and its contents. The matching design of the central circular mounting hole and flange enables precise positioning and reliable fixation of the preparation reactor.

[0020] Furthermore, the outer wall of the reactor is provided with multiple heat dissipation fins, which are distributed at equal intervals along the axial direction of the reactor.

[0021] The beneficial effects of adopting the above-mentioned improved scheme are as follows: the design of multiple heat dissipation fins evenly distributed along the axial direction increases the heat dissipation area of ​​the preparation reactor, improves heat dissipation efficiency, and effectively prevents excessive temperature accumulation during the reaction process. The heat dissipation fins help maintain the temperature stability of the reaction system, avoid the adverse effects of temperature fluctuations on the quality of vitamin C microcapsules, and extend the service life of the equipment.

[0022] Furthermore, the inner wall of the detection and acquisition body is provided with an annular guide groove, the depth of which is 2 mm to 5 mm.

[0023] The beneficial effects of adopting the above-mentioned improved scheme are as follows: the annular guide groove design on the inner wall of the sampling body can guide the collected fluid to form a regular flow path, reducing the generation of turbulence. The groove depth of 2 mm to 5 mm can effectively guide the flow without significantly affecting the overall strength of the sampling body. The annular guide groove helps to improve the sampling efficiency and reduce sample residue during the sampling process.

[0024] Furthermore, the upper surface of the sealing cover is provided with raised reinforcing ribs, which are distributed in a cross shape.

[0025] The beneficial effects of adopting the above-mentioned improved scheme are as follows: the design of the cross-shaped reinforcing ribs on the upper surface of the sealing cover plate significantly improves the bending strength and deformation resistance of the cover plate, enabling it to withstand the pressure inside the reactor. The raised reinforcing rib structure also enhances the sealing effect between the sealing cover plate and the feeding port, preventing leakage of the reaction system, while facilitating cleaning and maintenance.

[0026] Furthermore, there are 12 heat dissipation fins, which are evenly distributed along the circumference on the outer wall of the reactor.

[0027] The beneficial effects of adopting the above-mentioned improved scheme are as follows: the number of 12 heat dissipation fins has been optimized through calculation, ensuring sufficient heat dissipation while avoiding increased manufacturing costs caused by too many fins. The uniform distribution along the circumference ensures uniform heat dissipation, prevents the formation of local temperature gradients, and creates ideal temperature environment conditions for the stable preparation of vitamin C microcapsules.

[0028] Compared with existing technologies, the beneficial effects of the vitamin C microcapsule preparation detection and collection device provided by this utility model are as follows: Through the integrated design of the preparation reactor and the detection and collection device, real-time monitoring and sample collection of the vitamin C microcapsule preparation process are achieved, effectively solving the problems of detection lag and quality control difficulties in traditional preparation processes. The three-dimensional collection capability of the rotating collection arm ensures sample representativeness, the optimized design of the spiral stirring blades improves mixing uniformity, and the precise control of the temperature control system provides a stable temperature environment for the reaction. The filter screen and buffer storage chamber enable sample pretreatment and temporary storage, and the stable structure of the support base ensures the reliability of equipment operation. The coordinated operation of the entire device not only improves the preparation efficiency and product quality of vitamin C microcapsules but also provides a reliable technical means for industrial production. Compared with existing technologies, this utility model has significant advantages such as reasonable structure, simple operation, accurate detection, and stable control, and can meet the high standards of modern food and pharmaceutical industries for vitamin C microcapsule product quality.

[0049] The operating method of this utility model is as follows: First, install and debug the entire set of equipment to ensure that the support base is level and stable and that all components are tightly and reliably connected. Before starting the machine, check that the electrical wiring is correctly connected, the transmission mechanism is well lubricated, and the temperature control system is working normally. Prepare the required vitamin C solution and embedding material according to the formula ratio. Start the temperature control system, set the required reaction temperature value, and start the feeding operation after the temperature inside the preparation reactor reaches the set value. Add the embedding material and vitamin C solution sequentially through the feeding port, and cover the sealing cover after feeding is completed. Start the transmission mechanism and adjust the speed to a suitable range so that the spiral stirring blades start stirring and mixing. At the same time, start the detection and acquisition device, and the rotating acquisition arm starts to rotate and collect samples inside the reactor. During the preparation process, the temperature sensor monitors the reaction temperature in real time, and the temperature controller automatically adjusts the heating power to maintain a stable temperature. After the collected sample is filtered through a filter screen, it enters the buffer storage chamber and is then transported to external detection equipment through the collection pipeline for quality testing such as particle size analysis and embedding rate determination. Adjust the preparation process parameters in real time according to the test results, such as stirring speed, reaction temperature, and material ratio, to ensure that the product quality meets the requirements. After preparation, heating and stirring are stopped.

After use, the equipment is cleaned and maintained to prepare it for the next use.

[0050] Specifically, the principle of this invention is as follows: Through the integrated design of the preparation reactor and the detection and acquisition device, sample detection and acquisition are performed simultaneously during the preparation of vitamin C microcapsules. The spiral stirring blades inside the preparation reactor, driven by a transmission mechanism, generate a three-dimensional stirring flow field, ensuring thorough mixing of the vitamin C solution and the embedding material, promoting uniform microcapsule formation. The temperature control system provides a uniform temperature field through a heating sleeve, a temperature sensor monitors the reaction temperature in real time, and a temperature controller automatically adjusts the heating power according to the set value to maintain the optimal temperature conditions required for the preparation process. The rotating acquisition arm in the detection and acquisition device rotates slowly under the drive of a reduction transmission system, collecting samples at different locations within the reactor. Microcapsule particles meeting the particle size requirements are initially separated through a filter screen. The collected samples are first temporarily stored in a buffer storage chamber to avoid the impact of pipeline pressure fluctuations on sample quality, and then transported to external detection equipment for further analysis through the acquisition pipeline. The support base provides a stable foundation for the entire device; the rectangular distribution of the four support legs effectively resists vibration and torque during operation, and the height-adjustable spiral feet ensure horizontal installation of the equipment. The coordinated operation of the entire system enables continuous monitoring and quality control of the preparation process, significantly improving the preparation efficiency and product consistency of vitamin C microcapsules.
