Abstract
Description
Technical Field
[0001] This utility model belongs to the field of microcapsule drying technology, specifically a hemp oil microcapsule drying device. Background Technology
[0002] Hemp oil is rich in unsaturated fatty acids and other beneficial components, and has broad application prospects in food, cosmetics, and medicine. However, hemp oil is highly reactive and easily affected by external factors such as light, oxygen, temperature, and humidity, leading to oxidative rancidity and quality degradation, which greatly limits its application range. To solve this problem, microencapsulation technology has emerged. By encapsulating hemp oil inside a wall material to form microcapsules, external adverse factors can be effectively isolated, improving its stability and shelf life, and expanding its application scenarios. However, the drying process is crucial in the preparation of hemp oil microcapsules, directly affecting the quality, encapsulation rate, flowability, and storage stability of the microcapsules. Existing microcapsule drying devices generally have defects, such as uneven distribution of hot air leading to inconsistent heating of microcapsules, and the lack of an effective dispersion mechanism causing microcapsule accumulation and adhesion, resulting in low drying efficiency.

The lower end of the auger is fixedly connected to the stirring mechanism. The stirring mechanism works in conjunction with the second drying mechanism. The second drying mechanism is located on the drying chamber. The side wall of the drying chamber is provided with an exhaust mesh and a sealing door.

[0007] The hot air blower is fixed on the drying chamber. The air outlet of the hot air blower is connected to the inlet of the distribution pipe. The multiple distribution ends of the distribution pipe are evenly distributed from top to bottom and are all connected to the drying pipe.
[0008] The stir-frying mechanism includes a connecting rod, a protective chamber, a second bevel gear, a second motor, and two stirring units;
[0009] The upper end of the connecting rod is fixedly connected to the auger, and the lower end of the connecting rod is fixedly connected to the upper end of the protective chamber.

[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. Step-by-step drying ensures quality: A step-by-step drying method is adopted, consisting of low-temperature pre-drying and medium-temperature secondary drying. The low-temperature pre-drying stage slowly evaporates moisture from the surface of the hemp oil microcapsules, effectively preventing rapid softening of the microcapsule wall material due to excessively high temperatures, thus ensuring the structural integrity of the microcapsules. During the medium-temperature secondary drying, the escape of moisture from the inside of the microcapsules is accelerated. While ensuring the quality of the microcapsules, this significantly improves drying efficiency and quality, overcoming the problem of existing equipment potentially affecting microcapsule quality due to improper temperature control.
[0016] 2. Dual stirring enhances uniformity: The two C-shaped stirring rods in the stirring chamber and the stirring mechanism in the drying chamber create a dual stirring effect. The C-shaped stirring rods initially disperse the hemp oil microcapsules in the stirring chamber, separating the originally aggregated microcapsules. After entering the drying chamber, the arc-shaped shovel and the rotating protective chamber in the stirring mechanism work together to achieve all-round turning of the hemp oil microcapsules, effectively avoiding drying dead corners and ensuring a uniform and sufficient drying process. This solves the problem of existing devices lacking an effective dispersion mechanism, which leads to the accumulation of microcapsules and difficulty in uniform drying.
[0017] 3. High-efficiency, stable and reliable conveying: The auger is installed inside the drying tube. Its unique spiral structure can convey the initially dispersed hemp oil microcapsules in batches and in an orderly manner from the mixing chamber to the drying chamber. The precisely designed gap between the inner wall of the drying tube and the auger can effectively prevent the hemp oil microcapsules from falling off during the conveying process, ensuring the stability and continuity of the conveying process, reducing material loss and improving production efficiency.
[0018] 4. Scientific and reasonable hot air distribution: The multiple distribution ends of the diversion pipe of the drying mechanism one are evenly distributed from top to bottom and connected to the drying pipe, so that the hot air can fully contact the microcapsules during the auger conveying process; the mesh plate of the drying mechanism two works with the hood to evenly distribute the hot air in the drying chamber. This scientific hot air distribution design ensures that the microcapsules can fully contact the hot air at each stage of drying, further improving the drying effect and improving the situation of uneven heating of microcapsules caused by uneven hot air distribution in the existing device.
[0019] 5. Convenient operation and strong practicality: The exhaust vents on the side wall of the drying chamber can promptly discharge the moisture evaporated during the drying process, maintaining a dry environment inside the drying chamber; the sealed door design facilitates the removal of hemp oil microcapsules after drying; the entire device has a clear operation process, is easy to understand and implement, and has high practicality and promotional value.
[0020] In summary, this invention, through innovative structural design and scientific drying process, specifically addresses the problems existing in the prior art. While ensuring the quality of microcapsules, it significantly improves drying efficiency, uniformity, and practicality, demonstrating promising application prospects and technological advantages.

The lower end of the auger 6 is fixedly connected to the stirring mechanism. The stirring mechanism is used in conjunction with the drying mechanism 2. The drying mechanism 2 is located on the drying chamber 2. The side wall of the drying chamber 2 is provided with an exhaust mesh 21 and a sealing door 22.
[0027] The drying mechanism includes a hot air blower 15 and a distribution pipe 16.
[0028] The hot air blower 15 is fixed on the drying chamber 2. The air outlet of the hot air blower 15 is connected to the inlet of the diversion pipe 16. The multiple diversion ends of the diversion pipe 16 are evenly distributed from top to bottom and are all connected to the drying pipe 201.
[0029] The stir-frying mechanism includes a connecting rod 7, a protective chamber 8, a bevel gear 13, a motor 14, and two stirring units;
[0030] The upper end of the connecting rod 7 is fixedly connected to the auger 6, and the lower end of the connecting rod 7 is fixedly connected to the upper end of the protective chamber 8. The lower end of the protective chamber 8 is fixedly connected to the second motor 14. The output shaft of the second motor 14 rotates and passes into the protective chamber 8 and is fixedly connected to the second bevel gear 13. The second bevel gear 13 meshes with two stirring units. The two stirring units are symmetrically arranged and are both rotatably connected to the protective chamber 8.
[0031] Each of the stirring units includes an arc-shaped shovel plate 9, a rotating rod 10, a bearing 11, and a bevel gear 12;
[0032] The arc-shaped shovel plate 9 is fixedly connected to one end of the rotating rod 10. The rotating rod 10 is connected to the protective chamber 8 through the bearing 11. The other end of the rotating rod 10 is fixedly connected to the bevel gear 12. The bevel gear 12 meshes with the bevel gear 13.
[0033] The second drying mechanism includes a second hot air blower 17, a hot air pipe 18, a fan hood 19, and a mesh plate 20;
[0034] The second hot air blower 17 is fixed on the drying chamber 2. The air outlet of the second hot air blower 17 is connected to one end of the hot air pipe 18. The other end of the hot air pipe 18 is connected to the air hood 19. The air hood 19 is fixedly connected to the mesh plate 20. The mesh plate 20 is fixedly connected to the inner wall of the drying chamber 2.
[0035] When using this invention, the hemp oil microcapsules to be dried are poured into the mixing chamber 1 through the feed inlet at the top. The motor 4 is started via an external power source. Motor 4 drives the rotating rod 3 to rotate, and simultaneously, the two symmetrically arranged C-shaped stirring rods 5, which are fixedly connected to it, rotate accordingly. The lower end of the stirring rod 5 slides against the bottom surface of the stirring chamber 1. During rotation, it initially disperses the poured hemp oil microcapsules, separating the originally aggregated microcapsules and creating favorable conditions for subsequent drying, ensuring uniform drying. The auger 6, fixed at the lower end of the rotating rod 3, rotates within the drying tube 201 under the drive of the rotating rod 3. The unique spiral structure of the auger 6 allows it to transport the initially dispersed hemp oil microcapsules from the stirring chamber 1 to the drying chamber 2 in batches and in an orderly manner. The gap between the inner wall of the drying tube 201 and the auger 6 is precisely designed to effectively prevent the hemp oil microcapsules from falling during transport, ensuring the stability and continuity of the transport process. Simultaneously, the hot air blower 15 is started via an external power supply. The hot air blower 15 utilizes the adjustable temperature characteristic of existing technology, setting the temperature in a low-temperature range (preferably 35°C). Hot air generated by the hot air blower 15 (40℃) enters the drying tube 201 through multiple evenly distributed distribution ends of the distribution pipe 16. During the process of the auger 6 rotating and conveying the hemp oil microcapsules, the hemp oil microcapsules will come into contact with the hot air multiple times to achieve low-temperature pre-drying. This low-temperature environment can slowly evaporate the surface moisture of the hemp oil microcapsules, avoiding rapid softening of the hemp oil microcapsule wall material due to excessive temperature, thereby ensuring the structural integrity of the hemp oil microcapsules. After the hemp oil microcapsules are conveyed to the bottom surface of the drying chamber 2, the motor 14 is started by an external power supply. The output shaft of the motor 14 drives the bevel gear 13 to rotate in the protective chamber 8. Through the gear meshing principle, the bevel gear 13 drives the two bevel gears 12 meshing with it to rotate. Each bevel gear 12 is fixedly connected to the rotating rod 10, which in turn is connected to the protective chamber 8 via a bearing 11. Therefore, the rotation of the bevel gear 12 will drive the rotating rod 10 and the connected arc-shaped shovel 9 to rotate. The two arc-shaped shovels 9 are arranged in opposite directions. The unique arc design of the arc-shaped shovels 9 allows them to easily scoop up and stir the hemp oil microcapsules on the bottom surface of the drying chamber 2 during rotation, achieving all-round turning of the hemp oil microcapsules and avoiding drying dead corners. At the same time, the protective chamber 8 connected to the auger 6 will also rotate with the rotation of the auger 6, further enhancing the stirring effect. While stirring, the hot air blower 17 is started by an external power supply, and its temperature is adjusted to medium temperature (preferably 45°C). The hot air generated by the hot air blower 17 (at -50℃) enters the air hood 19 through the hot air pipe 18, and is then evenly distributed in the drying chamber 2 through the mesh plate 20 fixedly connected to the air hood 19. The medium-temperature hot air can accelerate the escape of moisture from the hemp oil microcapsules, and perform secondary drying on the hemp oil microcapsules that have been pre-dried at low temperature, thereby improving drying efficiency and drying quality. The moisture evaporated during the drying process is discharged outside the chamber through the exhaust mesh port 21 on the side wall of the drying chamber 2.Maintain a dry environment within drying chamber 2. Once the hemp oil microcapsules have reached the desired dryness, open the sealed door 22 on the side wall of drying chamber 2 to remove the dried hemp oil microcapsules, completing the entire drying process.
[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of the equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
