Description

Technical Field

[0001] This application relates to the technical field of supercritical extraction devices, and particularly to a supercritical extraction device for antioxidant rose raw liquid. Background Technique

[0002] Supercritical extraction is an extraction and separation technology that uses supercritical fluids as extractants. Supercritical fluids are a state of matter between gas and liquid, with a density close to that of a liquid and diffusion coefficient and viscosity close to those of a gas. This state can only exist when the temperature and pressure of the substance exceed its critical point. Supercritical extraction has many advantages, such as being non-toxic, non-flammable, inert, easy to obtain high purity, inexpensive, etc., and the operating conditions are mild, with little impact on the extract. Carbon dioxide is the most commonly used supercritical fluid because its critical temperature is close to room temperature and its critical pressure is relatively low, making it easy to operate and control. In the process of producing and preparing antioxidant rose raw liquid, a supercritical extraction device is required to extract and process the antioxidant rose raw liquid.

[0003] When the existing supercritical extraction device is in use, usually the rose juice is filled into a sealed container, and then the supercritical fluid (such as carbon dioxide) is heated and pressurized to exceed its critical point to form a supercritical state, and then injected into the container to contact and mix with the rose juice. By utilizing the high solubility of the supercritical fluid, the antioxidant solute in the rose is dissolved and precipitated, thereby realizing the extraction of the antioxidant rose raw liquid.

[0004] However, when using the above method, since the rose juice in the container is often mostly in a static state, when the supercritical fluid is injected into the container, it is often difficult to quickly and fully contact and mix with the juice raw material, resulting in a long time required for the reaction extraction of the juice raw material, and the extraction efficiency is relatively low. Therefore, those skilled in the art have provided a supercritical extraction device for antioxidant rose raw liquid to solve the problems raised in the above background technique.

[0024] An embodiment of the present application discloses a supercritical extraction device for an antioxidant rose original liquid. Referring to Figure 3 Figure 4 , a supercritical extraction device for an antioxidant rose original liquid includes an extraction tank 1. A plurality of support legs 101 are fixedly connected to the bottom of the extraction tank 1. A discharging mechanism 2 for discharging materials is arranged at the center of the bottom of the extraction tank 1. It also includes

[0025] a sufficient mixing mechanism 3, which is located at the center of the top of the extraction tank 1 for quickly stirring and mixing the raw materials and the extractant;

[0026] The scraping mechanism 7 is located at one end of the sufficient mixing mechanism 3 for scraping the raw materials adhered to the inner wall of the extraction tank 1.

[0027] The sufficient mixing mechanism 3 includes a hollow stirring frame 301, a plurality of discharge holes 302, a driving component 4, a feeding component 5, and a plurality of beating components 6. The hollow stirring frame 301 is rotatably connected to the center of the top of the extraction tank 1 through the top of the extraction tank 1. A plurality of discharge holes 302 are opened on the side wall of the hollow stirring frame 301. The driving component 4 is installed on the top of the extraction tank 1. The feeding component 5 is installed on the top of the extraction tank 1. A plurality of beating components 6 are installed on the side wall of the hollow stirring frame 301.

[0028] The driving component 4 includes a motor 401, a first transmission gear 402, and a second transmission gear 403. The bottom of the motor 401 is fixedly connected to the top of the extraction tank 1. The first transmission gear 402 is fixedly connected to the output end of the motor 401. The second transmission gear 403 is fixedly connected to the top of the hollow stirring frame 301, and the first transmission gear 402 meshes with the second transmission gear 403.

[0029] The feeding component 5 includes a fixing frame 501, a feeding pipe 502, a connecting block 503, and a feeding valve 504. The side wall of the feeding pipe 502 is fixedly connected to the top of the extraction tank 1 through the fixing frame 501. The bottom of the feeding pipe 502 is rotatably connected to the top of the hollow stirring frame 301 through the connecting block 503 and is communicated with the hollow stirring frame 301. The feeding valve 504 is fixedly connected to the side wall of the feeding pipe 502.

[0030] The beating component 6 includes two support frames 601, a rotating block 602, a beating plate 603, and two torsion springs 604. The two support frames 601 are symmetrically and fixedly connected to the side wall of the hollow stirring frame 301. One end of the beating plate 603 is rotatably connected between the two support frames 601 through the rotating block 602. The two ends of the two torsion springs 604 are respectively fixedly connected to the side walls of the two support frames 601 and the side wall of the rotating block 602.

[0031] In this embodiment, first, the feed valve 504 is opened to open the feed pipe 502. Then, the feed pipe 502 supported and fixed by the fixing frame 501 is opened to convey the rose juice raw material into the hollow stirring frame 301 connected thereto. The raw material enters the extraction tank 1 through the discharge hole 302 opened on the side wall of the hollow stirring frame 301. Then, the motor 401 is started to provide a driving force to drive the first transmission gear 402 connected thereto to rotate. The rotation of the first transmission gear 402 drives the second transmission gear 403 engaged therewith to rotate under force. The rotation of the second transmission gear 403 drives the hollow stirring frame 301 connected thereto to rotate at the center of the top of the extraction tank 1 under force. The rotation of the hollow stirring frame 301 can stir the rose juice raw material in the extraction tank 1. When the beating plate 603 collides with the raw material and is stressed, it rotates between the two support frames 601 through the rotating block 602 provided. The torsion spring 604 provides a reaction force to make the rotating block 602 rotate back under force. The rotation of the rotating block 602 drives the beating plate 603 to rotate back under force. In this way, the raw material can be beaten and dispersed by the rotation and back rotation of the beating plate 603, making the raw material evenly dispersed. At this time, similarly, the supercritical fluid is injected into the hollow stirring frame 301 by opening the feed pipe 502 again. In this way, while the rose juice raw material in the extraction tank 1 is stirred by the rotation of the hollow stirring frame 301, the supercritical fluid flowing out through the discharge hole 302 can quickly and fully and evenly contact and mix with the rose juice raw material, so as to realize the quick, full and even contact and mixing reaction between the rose juice raw material and the supercritical fluid, effectively saving the reaction time and improving the extraction efficiency.

[0032] Further, the scraping mechanism 7 includes a plurality of telescopic chutes 701, a plurality of springs 702, a plurality of telescopic rods 703 and a plurality of scraping plates 704. The plurality of telescopic chutes 701 are uniformly distributed and opened on the inner side of one end of the hollow stirring frame 301. One end of each of the plurality of telescopic rods 703 is elastically connected to one end of each of the plurality of telescopic chutes 701 through the plurality of springs 702. The side walls of the plurality of scraping plates 704 are respectively fixedly connected to the other ends of the plurality of telescopic rods 703.

[0033] On the basis of the above embodiment, while the raw material is stirred by the rotation of the hollow stirring frame 301, the spring 702 provides a driving force to make the telescopic rod 703 connected thereto slide out from the inside of the telescopic chute 701 under force. The extension of the telescopic rod 703 makes the scraping plate 704 connected thereto fit against the inner wall of the extraction tank 1 under force. At this time, the rotation of the hollow stirring frame 301 can drive the scraping plate 704 to rotate and scrape the inner wall of the extraction tank 1, realizing the effect of facilitating the scraping and cleaning of the raw material adhered to the inner wall of the extraction tank 1 and enabling the raw material to fully undergo the extraction reaction.

[0034] Further, the discharging mechanism 2 includes a discharging pipe 201 and a discharging valve 202. One end of the discharging pipe 201 is fixedly connected to the center of the bottom of the extraction tank 1, and the discharging valve 202 is fixedly connected to the side wall of the discharging pipe 201.

[0035] In this embodiment, after the reaction extraction, the discharging pipe 201 is opened by opening the set discharging valve 202. At this time, the product can be discharged from the extraction tank 1 through the opened discharging pipe 201.

[0036] The implementation principle of a supercritical extraction device for an antioxidant rose flower stock solution in an embodiment of the present application is as follows: When in use, first, the feed pipe 502 is opened by opening the feed valve 504. Then, the rose flower juice raw material is transported into the hollow stirring frame 301 connected thereto through the opened feed pipe 502 supported and fixed by the fixing frame 501, and the raw material enters the extraction tank 1 through the discharge holes 302 opened on the side wall of the hollow stirring frame 301. Then, the motor 401 is started to provide a force to drive the connected first transmission gear 402 to rotate. By the rotation of the first transmission gear 402, the engaged second transmission gear 403 is driven to rotate under force. By the rotation of the second transmission gear 403, the connected hollow stirring frame 301 is driven to rotate at the center of the top of the extraction tank 1 under force. By the rotation of the hollow stirring frame 301, the rose flower juice raw material in the extraction tank 1 can be stirred. And after the beating plate 603 collides with the raw material and is stressed, it rotates between the two support frames 601 through the rotating block 602, and the torsion spring 604 provides a reaction force to make the rotating block 602 rotate back under force. By the rotation back of the rotating block 602, the beating plate 603 is driven to rotate back under force. In this way, the raw material can be beaten and dispersed by the rotation and rotation back of the beating plate 603 to make the raw material evenly dispersed. At this time, similarly, the supercritical fluid is injected into the hollow stirring frame 301 by opening the feed pipe 502 again. In this way, while the rose flower juice raw material in the extraction tank 1 is stirred by the rotation of the hollow stirring frame 301, the supercritical fluid flowing out through the discharge holes 302 can quickly and fully and evenly contact and mix with the rose flower juice raw material, so as to effectively facilitate the stirring and mixing of the rose flower juice raw material and the supercritical fluid to make them quickly and fully and evenly mix and contact for reaction, effectively saving the reaction time and improving the extraction efficiency. Secondly, the spring 702 provides a force to make the connected telescopic rod 703 slide out from the inside of the telescopic chute 701 under force. By the extension of the telescopic rod 703, the connected scraping wall plate 704 is stressed to fit with the inner wall of the extraction tank 1. At this time, by the rotation of the hollow stirring frame 301, the scraping wall plate 704 can be driven to rotate to scrape the inner wall of the extraction tank 1, so as to effectively facilitate the scraping and cleaning of the raw material adhering to the inner wall of the extraction tank 1 and make the raw material fully undergo the extraction reaction. Finally, the discharge valve 202 is opened to open the discharge pipe 201. At this time, the product can be discharged from the extraction tank 1 through the opened discharge pipe 201 for unloading.

[0037] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
