Abstract
Description
Technical Field
[0001] This invention relates to the field of extraction and concentration technology, specifically to a miniaturized device for rapid extraction and concentration of active ingredients from fresh Chinese medicinal herbs. Background Technology
[0002] The active ingredients of fresh Chinese medicinal herbs refer to pharmacologically active substances such as alkaloids, flavonoids, polysaccharides, and volatile oils, which are widely used in Chinese medicine preparations, health products, and daily chemical products. The active ingredients in fresh herbs often coexist with large amounts of water and impurities, and some components are easily lost due to spoilage and oxidation. Extraction and concentration can separate and enrich the active ingredients, increasing their concentration and medicinal efficacy. Simultaneously, it removes useless impurities, reduces the volume of raw materials for easier storage, transportation, and subsequent processing, ensures stable finished product quality, and fully realizes the medicinal value of fresh Chinese medicinal herbs. Currently, the concentration of effective components from fresh Chinese medicinal herbs is mostly achieved through vacuum extraction pipes at the top of the concentration tank. However, this method can only extract the gas in the upper space of the tank, and the gas remaining in the liquid extract is difficult to be fully extracted, which easily leads to the generation of a large number of bubbles during the concentration process. This not only reduces the efficiency of vacuum concentration but also affects the rate of water evaporation. Therefore, it is necessary to propose a miniaturized rapid extraction and concentration device for effective components from fresh Chinese medicinal herbs. Summary of the Invention
[0003] To address the problems in the prior art, this invention provides a miniaturized device for rapid extraction and concentration of effective components from fresh Chinese medicinal herbs.
[0004] The technical solution adopted by the present invention to solve its technical problem is: a miniaturized rapid extraction and concentration device for effective components of fresh Chinese medicinal herbs, including a frame, on which an ultrasonic extraction component is provided; A concentration tank is installed on the other side of the frame. An auxiliary vacuum assembly is provided at the top of the concentration tank. The auxiliary vacuum assembly includes a support frame installed at the top of the concentration tank. A servo motor is installed on the inner top wall of the support frame. A transmission shaft is fixedly connected to the output end of the servo motor. A transmission gear is fixedly connected to one end of the transmission shaft. A rotating rod is rotatably connected through the top of the concentration tank. A driven gear that meshes with the transmission gear is fixedly connected to the upper end of the rotating rod wall. Multiple sets of stirring rods are fixedly connected to the rotating rod wall. The stirring rod has a through hole, and a vacuum tube and a heating tube are respectively embedded at the top of the rotating rod. The inner end of the through hole is provided with a vacuum branch pipe and a heat conduction pipe distributed in a spiral shape. Multiple vacuum taps are embedded in the curved inner section of the vacuum branch pipe, and several protruding blades are fixedly connected to the wall of the heat conduction pipe.
[0005] Specifically, the ultrasonic extraction assembly includes an extraction tank installed on the other side of the frame, a feed pipe embedded at the top of the extraction tank, an annular ultrasonic vibrating plate sleeved on the outer wall of the extraction tank, a pump body installed at the bottom of the extraction tank, and a guide pipe fixedly connected to the output end of the pump body and connected to the concentration tank.
[0006] Specifically, the frame is equipped with an ultrasonic generator, and the ultrasonic generator is electrically connected to the annular ultrasonic transducer plate.
[0007] Specifically, the lower end of the wall of the concentration tank is provided with two liquid outlet pipes, the bottom of the concentration tank is provided with a discharge pipe, and the outer wall of the concentration tank is fitted with a low-temperature refrigeration jacket.
[0008] Specifically, the heat pipe is spirally wrapped around the outer end of the vacuum manifold.
[0009] Specifically, an L-shaped limiting block is fixedly connected to the top of the concentration tank, and a connecting rotating block is fixedly connected to one end of the limiting block. The connecting rotating block is connected to the vacuum tube and the heating tube, and the connecting rotating block is rotatably connected to the rotating rod.
[0010] The beneficial effects of this invention are as follows: This invention significantly improves the efficiency and effectiveness of concentration operations. The stirring rod integrates a spirally distributed heat-conducting pipe and a vacuum pipe, which enables uniform heat transfer and precise gas extraction during the stirring process, allowing the extract to be heated and degassed more evenly. The raised blades on the wall of the heat-conducting pipe can efficiently break up the bubbles generated by low-temperature stirring, causing the residual gas in the extract to escape quickly and improving the degassed efficiency. At the same time, the concentration tank is equipped with separate liquid outlet pipes and material outlet pipes to achieve separate discharge of concentrate and waste residue, further ensuring the purity of the concentrated product.

[0014] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0015] like Figures 1-7 As shown, the present invention provides the following technical solution: Example 1: A miniaturized rapid extraction and concentration device for effective components of fresh Chinese herbal medicine includes a frame 1, an ultrasonic extraction component 2 on the frame 1, an extraction tank 21 installed on the other side of the frame 1, a feed pipe 22 embedded at the top of the extraction tank 21, an annular ultrasonic vibrating plate 23 sleeved on the outer wall of the extraction tank 21, a pump body 24 installed at the bottom of the extraction tank 21, a guide pipe 25 fixedly connected to the output end of the pump body 24 and connected to the concentration tank 3, an ultrasonic generator 10 on the frame 1, and the ultrasonic generator 10 is electrically connected to the annular ultrasonic vibrating plate 23.
[0016] In use, fresh Chinese medicinal materials are fed into the extraction tank 21 through the feed pipe 22. After adding an appropriate amount of extraction solvent into the tank, the ultrasonic generator 10 is started to power the annular ultrasonic transducer 23. The annular ultrasonic transducer 23 generates high-frequency ultrasonic vibration and transmits it to the raw materials and solvent in the extraction tank 21. The effective components of the fresh Chinese medicinal materials are rapidly extracted through ultrasonic cavitation. After extraction, the pump 24 is started, and the extract is transported to the concentration tank 3 through the feed pipe 25 to prepare for the subsequent concentration process.
[0017] Example 2: The technical solution of this example, which differs from that of Example 1, includes: a concentration tank 3 is installed on the other side of the frame 1, an auxiliary vacuum assembly 4 is provided at the top of the concentration tank 3, the auxiliary vacuum assembly 4 includes a support frame 41 installed at the top of the concentration tank 3, a servo motor 42 is installed on the inner top wall of the support frame 41, a transmission shaft is fixedly connected to the output end of the servo motor 42, a transmission gear 43 is fixedly connected to one end of the transmission shaft, a rotating rod 44 is rotatably connected through the top of the concentration tank 3, a driven gear 442 that meshes with the transmission gear 43 is fixedly connected to the upper end of the rod wall of the rotating rod 44, multiple sets of stirring rods 45 are fixedly connected to the rod wall of the rotating rod 44, two liquid outlet pipes 31 are embedded at the lower end of the tank wall of the concentration tank 3, a discharge pipe 32 is embedded at the bottom of the tank of the concentration tank 3, and a low-temperature refrigeration jacket 33 is sleeved on the outer wall of the concentration tank 3.
[0018] The cryogenic refrigeration jacket 33 mainly consists of a jacket shell, a refrigeration coil, a liquid inlet, a liquid outlet, and an insulation layer, and some of it includes a temperature sensor and a seal (existing technology).
[0019] In use, the effective components of fresh products are extracted by the ultrasonic extraction component 2. After the extract is introduced into the concentration tank 3 through the feed pipe 25, the low-temperature cooling jacket 33 is activated to control the temperature of the tank wall of the concentration tank 3 at low temperature and create a low-temperature concentration environment. At the same time, the servo motor 42 is activated. The servo motor 42 drives the transmission gear 43 to rotate through the transmission shaft. The meshing driven gear 442 synchronously drives the rotating rod 44 and multiple sets of stirring rods 45 to rotate, so as to stir the extract in the tank at a uniform speed, so that the extract is heated and vacuumed evenly. During the stirring process, the staged concentrate can be discharged from the liquid outlet pipe 31 according to the concentration progress. After the concentration is completed, the remaining waste residue is discharged from the discharge pipe 32.
[0020] Example 3: The technical solution of this example, which differs from that of Example 1, includes: a through hole 401 is provided through the stirring rod 45; a vacuum tube 46 and a heating tube 47 are respectively embedded at the top of the rotating rod 44; a vacuum branch pipe 460 and a heat conduction pipe 470 are respectively provided in a spiral arrangement at the inner end of the through hole 401; multiple vacuum taps 461 are embedded in the curved inner section of the vacuum branch pipe 460; several protruding blades 471 are fixedly connected to the wall of the heat conduction pipe 470; the heat conduction pipe 470 is spirally wrapped around the outer end of the vacuum branch pipe 460; a limiting block 441 in an L-shape is fixedly connected to the top of the concentration tank 3; a connecting rotating block 440 is fixedly connected to one end of the limiting block 441; the connecting rotating block 440 is connected to the vacuum tube 46 and the heating tube 47; and the connecting rotating block 440 is rotatably connected to the rotating rod 44.
[0021] Among them, the main vacuum pipe is embedded in the upper part of the 3-tank body of the concentration tank; In use, after the extract is introduced into the concentration tank 3, the inside of the concentration tank 3 is first initially evacuated through the main vacuum tube. Then, the input ends of the vacuum tube 46 and the heating tube 47 are connected to the external vacuum equipment and heating equipment, respectively. The servo motor 42 is started to drive the rotating rod 44 to rotate, and the rotating rod 44 drives the stirring rod 45 to rotate synchronously. While stirring and mixing the extract, the vacuum extraction efficiency inside the tank is improved. The vacuum tube 46 accurately extracts the residual gas in the extract through the vacuum branch pipe 460 and the vacuum tap 461. The spiral heat-conducting tube 470 evenly transfers heat to the extract. Stirring in a low-temperature environment causes bubbles to be generated in the extract. The protruding blades 471 on the wall of the heat-conducting tube 470 break the bubbles, causing the gas in the extract to quickly overflow and be removed, thus improving the concentration effect. After the low-temperature vacuum concentration is completed, the concentrate is discharged from the liquid outlet pipe 31, and the waste residue generated after extraction is discharged from the material outlet pipe 32.
