Description

Technical Field

[0001] This utility model relates to the technical field of fragrance and flavor extraction, and in particular to a high-efficiency fragrance and flavor extraction device. Background Technology

[0002] Fragrances and flavors are a class of natural or synthetic substances that can be perceived through smell or taste, providing characteristic aromas and flavors or masking unpleasant odors for products such as food, daily chemicals, and pharmaceuticals. They are core raw materials for "sensory experience design" in modern industry. Extraction is an important process in the production of fragrances and flavors. Extraction refers to the process of separating and extracting active ingredients with characteristic aromas or flavors from natural plant and animal raw materials using principles such as solvent dissolution, physical adsorption, and steam separation. The extraction vessel is an important piece of equipment for the extraction process. Therefore, there is a particular need for a high-efficiency fragrance and flavor extraction device.

[0003] However, most existing high-efficiency flavor and fragrance extraction equipment has an auxiliary stirring structure inside the extraction vessel. The stirring structure can accelerate the contact between the solvent and the material, ensure the uniformity of mixing, and improve the extraction effect. However, most of the stirring structures in the extraction vessel cannot scrape the inner wall of the extraction vessel. During extraction, the material may stick to the inner wall of the extraction vessel and cannot fall off, which will affect the extraction effect.

[0004] To address the aforementioned issues, a search revealed a patent with publication number CN105641970A that discloses an extraction vessel. The patent states that "because oat bran powder (hereinafter referred to as the material) contains particles larger than 40 mesh (10%), powders between 40 and 80 mesh (40%), and fine powder larger than 80 mesh (50%), with an oil content of approximately 8%, and the material has strong plasticity, during the extraction process, supercritical carbon dioxide fluid flows directly through the channels formed between the relatively loose materials. A large amount of supercritical carbon dioxide fluid does not contact the material and directly enters the subsequent process through the channels. This leads to: 1. Incomplete extraction and low oil yield; 2. Agglomeration of materials that do not contact the supercritical carbon dioxide fluid under pressure. To increase the interaction between supercritical carbon dioxide and the material..." To increase the contact area between the material and the supercritical carbon dioxide fluid, packing materials such as Pall rings are typically added to the extraction vessel. Pall rings are circular rings made of inert material with perforated walls, which greatly improves the utilization rate of the internal space and surface area of ​​the ring, allowing the supercritical carbon dioxide fluid to be evenly distributed in the extraction vessel. This ensures that the material and the supercritical carbon dioxide fluid are in full contact, thereby increasing the oil yield and preventing agglomeration. However, adding packing materials requires additional equipment for mixing the material with the packing material before extraction and for separating the material from the packing material after extraction, which greatly increases the workload and lengthens the working cycle. This invention discloses an extraction vessel, including an extraction vessel body and a partition mesh assembly for separating the material. The partition mesh assembly is installed inside the extraction vessel body and has a mesh. By installing a mesh assembly on the inner wall of the extraction vessel body to separate the material, the contact area between the material and the supercritical carbon dioxide fluid is increased. Since the mesh assembly is installed on the inner wall of the extraction vessel body, there is no need for mixing or separating the material from the mesh assembly. In practice, the material is simply added to the extraction vessel body, and then supercritical carbon dioxide fluid is directly added for extraction. After extraction, the material is directly discharged, reducing the mixing and separation process using packing materials, shortening the extraction cycle, and improving production efficiency. However, the stirring structure in most extraction vessels cannot scrape the inner wall of the extraction vessel, and the material may stick to the inner wall during extraction, affecting the extraction effect.

[0005] In light of this, in-depth research into the aforementioned issues led to the creation of this case. Utility Model Content

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.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a high-efficiency fragrance and flavor extraction device, including an extraction vessel 1, a wall scraping mechanism 2 is provided at one end of the extraction vessel 1, and a stirring mechanism 3 is provided at one end of the wall scraping mechanism 2; The wall scraping mechanism 2 includes a motor 201, with a connecting rod 202 connected to the output end of the motor 201. A connecting frame 203 is mounted on the outer wall of the connecting rod 202, and a spring 204 is installed inside the connecting frame 203. A scraper 205 is mounted on one end of the spring 204. An auxiliary rod 206 is mounted on one inner wall of the connecting frame 203, and a moving rod 207 is mounted on one side of the scraper 205. A connecting plate 208 is fixedly mounted on one side of the connecting frame 203, and a rubber pad 209 is adhered to the inner wall of the connecting plate 208. The mechanism is connected via an extraction vessel 1, a motor 201, a connecting rod 202, a connecting frame 203, a spring 204, a scraper 205, an auxiliary rod 206, a moving rod 207, and a connecting rod 209. The installation of plate 208 and rubber pad 209 ensures that when connecting rod 202 rotates for stirring, connecting frame 203 will also rotate. At this time, scraper 205, which is attached to the inner wall of extraction vessel 1, can scrape the inner wall to prevent material from sticking to the inner wall of extraction vessel 1 and preventing it from falling off, thus ensuring the extraction effect. Under the action of spring 204, scraper 205 will always be attached to the inner wall of extraction vessel 1, ensuring the scraping effect of scraper 205. When scraper 205 is moved by spring 204, moving rod 207 will move at one end of auxiliary rod 206. Moving rod 207 and auxiliary rod 206 can assist and limit the extension and retraction of spring 204 and scraper 205.

[0019] Furthermore, the connecting rod 202 is connected to the extraction vessel 1 via a bearing, and the connecting frame 203 forms a rotating structure with the extraction vessel 1 via the connecting rod 202. With the setting of the connecting rod 202, the connecting rod 202 can rotate the connecting frame 203 and the first stirring rod 308, which can stir the inside of the extraction vessel 1 and improve the extraction effect.

[0020] Furthermore, the scraper 205 forms a telescopic structure with the connecting frame 203 via the spring 204. One end of the moving rod 207 is sleeved on the outer wall of the auxiliary rod 206. With the setting of the scraper 205, when the scraper 205 is rotated by the connecting frame 203, it can scrape off the material stuck to the inner wall of the extraction vessel 1, causing the material stuck to the inner wall of the extraction vessel 1 to fall off, thereby improving the extraction effect.

[0021] Furthermore, the stirring mechanism 3 includes a mounting plate 301, a protective shell 302 mounted on one side surface of the mounting plate 301, a connecting column 303 mounted on one end of the mounting plate 301, a first bevel gear 304 mounted on one end of the connecting rod 202, a second bevel gear 305 mounted on one end of the connecting column 303, a mounting column 306 mounted on the inner wall of one side of the protective shell 302, a third bevel gear 307 mounted on one end of the mounting column 306, a first stirring rod 308 mounted on the outer wall of the connecting rod 202, a second stirring rod 309 mounted on the outer wall of the connecting column 303, and a third stirring rod 310 mounted on the outer wall of the connecting column 303. The stirring mechanism 3 is connected by the mounting plate 301, protective shell 302, connecting column 303, first bevel gear 304, second bevel gear 305, mounting column 306, and third bevel gear 307. The arrangement of gear 307, first stirring rod 308, second stirring rod 309, and third stirring rod 310 allows the connecting rod 202 to rotate the first stirring rod 308 during stirring. At this time, the first bevel gear 304, which is fixedly installed at one end of the connecting rod 202, will rotate the third bevel gear 307 that meshes with it. When the third bevel gear 307 rotates at one end of the mounting column 306, the second bevel gear 305 that meshes with it will rotate the connecting column 303, allowing the connecting column 303 to rotate the second stirring rod 309 and the third stirring rod 310. The rotation direction of the second stirring rod 309 and the third stirring rod 310 is opposite to the rotation direction of the first stirring rod 308, forming a highly efficient bidirectional stirring structure, which improves the stirring effect and the extraction effect.

[0022] Furthermore, the first bevel gear 304 forms a rotating structure with the protective shell 302 through the connecting rod 202. The first bevel gear 304 and the third bevel gear 307 are meshed. With the first bevel gear 304, when the connecting rod 202 rotates, it will drive the first bevel gear 304 to rotate. The rotating first bevel gear 304 can drive the third bevel gear 307, which is meshed with it, to rotate.

[0023] Furthermore, the second bevel gear 305 forms a rotating structure with the mounting plate 301 via the connecting column 303. The second bevel gear 305 and the third bevel gear 307 are meshed. With the second bevel gear 305, when the third bevel gear 307 rotates, the second bevel gear 305 meshing with it will be rotated. The second bevel gear 305 can rotate the connecting column 303 at one end of the mounting plate 301, and the rotation direction of the connecting column 303 is opposite to that of the connecting rod 202, forming a bidirectional stirring structure and improving the stirring effect.

[0024] Furthermore, the first stirring rod 308 is installed at equal intervals on the outer wall of the connecting rod 202, and the second stirring rod 309 is installed at equal intervals on the outer wall of the connecting column 303. The second stirring rod 309 forms a rotating structure with the mounting plate 301 through the connecting column 303. The first stirring rod 308 and the second stirring rod 309 can rotate in opposite directions to perform bidirectional and efficient stirring inside the extraction vessel 1, thereby improving the extraction effect.

[0025] Working principle: When the connecting rod 202 rotates to perform stirring, the connecting frame 203 will also rotate. At this time, the scraper 205, which is attached to the inner wall of the extraction vessel 1, can scrape off the material, preventing it from sticking to the inner wall of the extraction vessel 1 and ensuring the extraction effect. Under the action of the spring 204, the scraper 205 will always be attached to the inner wall of the extraction vessel 1, ensuring the scraping effect of the scraper 205. When the scraper 205 is moved by the spring 204, the moving rod 207 will move at one end of the auxiliary rod 206. The moving rod 207 and the auxiliary rod 206 can assist and limit the extension and retraction of the spring 204 and the scraper 205, thus performing stirring. During the mixing process, the connecting rod 202 rotates the first stirring rod 308. At this time, the first bevel gear 304, which is fixedly installed at one end of the connecting rod 202, rotates the third bevel gear 307 that meshes with it. When the third bevel gear 307 rotates at one end of the mounting column 306, the second bevel gear 305 that meshes with it rotates the connecting column 303. This allows the connecting column 303 to rotate the second stirring rod 309 and the third stirring rod 310. The rotation direction of the second stirring rod 309 and the third stirring rod 310 is opposite to the rotation direction of the first stirring rod 308, forming a highly efficient bidirectional stirring structure, which improves the stirring effect and the extraction effect.
