Description

Technical Field

[0001] This utility model relates to the field of encapsulation device technology, and more specifically to an encapsulation device for volatile oils. Background Technology

[0002] Volatile oils are a class of natural, aromatic, oily liquids, often possessing pharmacological activities such as expectorant, antitussive, antiasthmatic, antipyretic, analgesic, carminative, antibacterial, and anti-inflammatory properties. Given their susceptibility to volatilization and loss under heat, volatile oils are typically prepared as cyclodextrin inclusion complexes in traditional Chinese medicine preparations before being formulated into finished products, thus preventing volatile oil dispersion. Inclusion complexes utilize molecules like cyclodextrins, which have a "cavity" structure, to encapsulate volatile oil molecules, forming stable inclusion complexes. These complexes prevent volatile oil volatilization or decomposition, increase their solubility in water, and facilitate the formulation into solid dosage forms. During production, stirring equipment is used to mix the volatile oils and cyclodextrins together to prevent volatilization.

[0003] Current volatile oil encapsulation devices still have the following problems in use: 1. Existing volatile oil encapsulation equipment mostly uses unidirectional or unidirectional stirring, which results in poor mixing effect and easily creates stirring dead zones, leading to uneven mixing of volatile oil and excipients such as cyclodextrin, low encapsulation rate, and unstable product quality.

[0004] 2. Traditional equipment typically uses fixed nozzles or intermittent feeding methods to add volatile oils, resulting in poor atomization, uneven droplets, and an insufficient contact area with solid materials, leading to slow inclusion reaction rates and low production efficiency.

[0005] 3. In existing equipment, materials tend to adhere to the inner wall of the tank and the stirring rod, resulting in material waste and cleaning difficulties. This not only affects the material utilization rate but also makes it difficult to ensure the consistency of product quality between batches.

[0006] Therefore, it is necessary to propose a volatile oil encapsulation device to solve the above problems. Utility Model Content

[0007] To address the above problems, this utility model provides a volatile oil encapsulation device, which improves the encapsulation effect and enhances the stirring effect.

[0008] To achieve the above objectives, this utility model specifically adopts the following technical solution: A volatile oil encapsulation device includes a tank, a stirring rod rotatably connected inside the tank, a support rod connected to the inner wall of the tank, a protective cover connected to the support rod, a driving helical gear connected to the stirring rod and located inside the protective cover, a reversing helical gear located below the driving helical gear, a driven helical gear rotatably connected inside the protective cover and located between the driving helical gear and the reversing helical gear, a connecting frame connected to the bottom of the reversing helical gear, a rotating ring connected to the outer ring surface of the connecting frame, and an atomizing nozzle connected to the bottom of the rotating ring. The bottom of the support rod is connected to a fixed ring, the bottom of the fixed ring is rotatably connected to a rotating ring, the bottom of the fixed ring is provided with an annular groove, a material tube is installed inside the support rod, a feeding device is connected to the outside of the material tube, the material tube is connected to the annular groove, and a through hole is provided on the rotating ring to connect the atomizing nozzle and the annular groove.

[0009] Preferably, in order to improve the encapsulation effect, the bottom of the stirring rod is connected to a lower stirring blade, and the bottom of the connecting frame is connected to an upper stirring blade.

[0010] Preferably, in order to prevent material from sticking to the stirring rod and to improve the efficiency of material moving to the outer ring, a spiral frame is rotatably connected to the outer wall of the stirring rod, and the spiral frame is connected to the outer wall of the upper stirring blade.

[0011] Preferably, in order to facilitate scraping off the material adhering to the barrel wall, a scraper is connected to the outer edge of the lower stirring blade.

[0012] Preferably, in order to improve the stability of the rotating ring during rotation, a stabilizing frame is connected to the bottom of the support rod, and the stabilizing frame is rotatably connected to the rotating ring.

[0013] Preferably, to facilitate the addition of solid materials, a material inlet is connected to the top of the tank.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By setting up driving helical gears, driven helical gears, and reversing helical gears, the stirring rod and atomizing nozzle rotate in opposite directions. The upper and lower stirring blades form strong convection mixing, eliminating dead zones in the mixing process, resulting in more thorough and uniform mixing of volatile oil and cyclodextrin, thereby significantly improving inclusion efficiency and product quality.

[0015] 2. By setting a rotating sealing structure with a rotating ring, a fixed ring, and an annular groove, the volatile oil is continuously supplied while the atomizing nozzle rotates at high speed. This not only ensures the uniform atomization of the volatile oil and increases its contact surface area with cyclodextrin, but also accelerates the inclusion reaction rate and improves production efficiency.

[0016] 3. By installing scrapers on the outer edge of the lower stirring blades and spiral frames on the outer wall of the stirring rod, the problems of material sticking to the wall and adhering to the stirring rod are effectively solved. The scrapers scrape the material off the tank wall, and the spiral frames prevent material accumulation, ensuring that all materials can participate in the reaction, improving material utilization, reducing waste, and ensuring the consistency of products between batches.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] In this case, the selection of materials, heat treatment processes, and structural dimensions of conventional and critical load-bearing components all conform to standards. The existing material properties are all suitable for use under this condition, ensuring sufficient strength, stiffness, and fatigue resistance under rated load and expected operating conditions, such as springs. These are all conventional design considerations well known to those skilled in the art.

[0021] Please see Figure 1-5A volatile oil encapsulation device includes a tank 101. A stirring rod 102 is rotatably connected inside the tank 101. A motor is connected to the top of the tank 101, and the motor's output is connected to the stirring rod 102, driving the stirring rod 102 to rotate. A coupling is provided at the connection point. A heating structure is provided on the tank 101 to increase the temperature during stirring; this is a standard feature of the equipment and will not be described in detail here. A support rod 103 is connected to the inner wall of the tank 101, and a protective cover 104 is connected to the support rod 103, providing protection. A driving helical gear 105 is connected to the stirring rod 102 and located inside the protective cover 104. A reversing helical gear 106 is located below the driving helical gear 105. A driven helical gear 107 is rotatably connected inside the protective cover 104, positioned between the driving helical gear 105 and the reversing helical gear 106. Through a three-stage helical gear transmission system—the driving helical gear 105, the driven helical gear 107, and the reversing helical gear 106—the unidirectional rotation of the stirring rod 102 is converted into the reverse rotation of the reversing helical gear 106. The protective cover 104 protects the gear system and prevents material from entering the transmission components. A support rod 103 is fixed to the wall of the tank 101, providing stable support for the entire transmission system. This design achieves reverse movement of the stirring and atomizing components, greatly improving material mixing efficiency. The bottom of the reversing helical gear 106 is connected to a connecting frame 108, the outer ring surface of the connecting frame 108 is connected to a rotating ring 109, and the bottom of the rotating ring 109 is connected to an atomizing nozzle 110. The atomizing nozzle 110 is a mature existing structure and will not be described in detail here. A fixed ring 111 is connected to the bottom of the support rod 103. The bottom of the fixed ring 111 is rotatably connected to the rotating ring 109. An annular groove 112 is formed at the bottom of the fixed ring 111. A material pipe 113 is installed inside the support rod 103. A feeding device, which is a volatile oil supply device, is connected to the outside of the material pipe 113. The material pipe 113 is connected to the annular groove 112. A through hole 114 is formed on the rotating ring 109, connecting the atomizing nozzle 110 and the annular groove 112. The annular groove 112 is an annular groove into which liquid material enters. Regardless of how the rotating ring 109 rotates, the through hole 114 is always connected to the annular groove 112, realizing continuous material supply during rotation. The reversing helical gear 106 drives the connecting frame 108 and the rotating ring 109 to rotate. The fixed ring 111 and the rotating ring 109 form a rotary sealing structure. The material enters the annular groove 112 of the fixed ring 111 through the material pipe 113, and then enters the atomizing nozzle 110 through the through hole 114 on the rotating ring 109. This design allows the atomizing nozzle 110 to continuously receive material while rotating, and achieves uniform atomization of volatile oil through the combined action of centrifugal force and pressure, increasing the contact area with cyclodextrin and improving the inclusion efficiency.

[0022] Specifically, to improve the inclusion effect, a lower stirring blade 115 is connected to the bottom of the stirring rod 102, and an upper stirring blade 116 is connected to the bottom of the connecting frame 108. A double-layer stirring blade design is adopted, with the upper stirring blade 116 rotating with the connecting frame 108 and the lower stirring blade 115 rotating with the stirring rod 102. Due to the gear transmission system, the upper and lower stirring blades 115 rotate in opposite directions, creating a convective stirring effect. This design can generate a complex flow field, avoid dead zones in material mixing, promote full contact between volatile oil atomized particles and cyclodextrin, and improve the inclusion reaction rate and uniformity.

[0023] Specifically, to prevent material from adhering to the stirring rod 102 and improve the efficiency of material movement to the outer ring, a spiral frame 117 is rotatably connected to the outer wall of the stirring rod 102. The spiral frame 117 is connected to the outer wall of the upper stirring blade 116. The spiral frame 117 is connected to the upper stirring blade 116 and rotates with the upper stirring blade 116 (in the opposite direction of rotation to the stirring rod 102). Its spiral structure generates a downward pushing force when rotating, which can prevent material from adhering and accumulating on the surface of the stirring rod 102, while promoting the movement of material to the outside of the tank 101, increasing the contact opportunity with the atomization area, reducing material waste, and improving the mixing uniformity and overall encapsulation efficiency.

[0024] Specifically, to facilitate scraping off material adhering to the tank wall, a scraper 118 is connected to the outer edge of the lower stirring blade 115. The scraper 118 is installed on the outer edge of the lower stirring blade 115 and rotates with it, its edge in close contact with the inner wall of the tank 101. During rotation, the scraper 118 effectively removes material adhering to the tank wall, preventing waste caused by material sticking to the wall. This design ensures that all materials participate in the mixing and inclusion reaction, improving material utilization and reaction uniformity, while also facilitating equipment cleaning and maintenance.

[0025] Specifically, to improve the stability of the rotating ring 109 during rotation, a stabilizing frame 119 is connected to the bottom of the support rod 103, and the stabilizing frame 119 is rotatably connected to the rotating ring 109. The stabilizing frame 119 extends from the bottom of the support rod 103 to the rotating ring 109, forming an additional support point. Since the rotating ring 109 carries the atomizing nozzle 110 and needs to rotate at high speed, the stabilizing frame 119 can effectively reduce the radial sway and vibration of the rotating ring 109, ensuring the stable operation and uniform spray of the atomizing nozzle 110. This design improves the stability and reliability of the equipment operation and extends its service life.

[0026] Specifically, to facilitate the addition of solid materials, a material inlet 120 is connected to the top of the tank 101. The material inlet 120, located at the top of the tank 101, is used for adding solid materials (such as cyclodextrin). Its location is designed for ease of operation and avoids sealing problems that might occur with openings on the side of the tank 101. The top-addition method allows materials to fall naturally into the mixing area, reducing material residue and improving addition efficiency and ease of operation.

[0027] There are two possible combinations when encapsulating volatile oils: The first type is volatile oil (liquid) and solid encapsulation material (powder). The solid material is added into the equipment through the material inlet 120 at the top, and the liquid is sprayed into the tank 101 through the atomizing nozzle 110 to perform the encapsulation action.

[0028] The second type involves volatile oil (liquid, dispersed phase) and inclusion material solution (liquid, continuous phase). In this case, the atomizing nozzle 110 is a dual-liquid composite atomizing nozzle, used for spraying and mixing the two liquid materials. The support rod 103 has two material pipes 113, which supply materials to the two channels of the atomizing nozzle 110 respectively. The inner channel supplies volatile oil, and the outer channel supplies inclusion material solution, such as a paste of cyclodextrin and water.

[0029] In this embodiment, the usage method is as follows: Solid materials such as cyclodextrin are added to tank 101 through material addition port 120. The stirring system is then activated, and stirring rod 102 drives lower stirring blades 115 to rotate. Through a gear transmission system, driving helical gear 105 drives reverse helical gear 106 to rotate in the opposite direction via driven helical gear 107. Reverse helical gear 106 drives rotating ring 109 and upper stirring blades 116 to rotate in the opposite direction via connecting frame 108. Volatile oil enters the rotating atomizing nozzle 110 through material pipe 113, annular groove 112, and through hole 114, where it is atomized into fine particles. The reverse rotation of upper and lower stirring blades 115 creates strong convection, ensuring thorough contact and mixing of the atomized volatile oil and cyclodextrin. Spiral frame 117 prevents material from adhering to stirring rod 102, and scraper 118 removes material from the tank wall, ensuring all materials participate in the reaction.

[0030] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
