Description

Technical Field

[0001] This utility model relates to the field of ginsenoside extraction technology, and in particular to an ultrasonic-assisted extraction device for ginsenosides. Background Technology

[0002] Ginsenosides, as the core active ingredients of ginseng, possess extremely high medicinal value and health benefits. Their effective extraction is a crucial step in realizing the industrial application of ginseng resources. Traditional ginsenoside extraction methods (such as solvent soaking and reflux heating) generally suffer from low extraction efficiency, long extraction times, high solvent consumption, and the potential for damaging the structure of heat-sensitive saponins. Ultrasonic-assisted extraction technology, with its unique mechanism of action, demonstrates significant advantages in the field of ginsenoside extraction: the cavitation effect generated by ultrasound in the extraction system can form a large number of microbubbles. The instantaneous high pressure released when these bubbles burst can effectively disrupt the cell wall structure of ginseng, reducing mass transfer resistance. Simultaneously, the mechanical vibration and localized thermal effects of ultrasound can enhance the contact efficiency between the extraction solvent and the ginseng raw material, accelerating the dissolution of ginsenosides from the raw material into the solvent. This shortens the extraction time, reduces solvent consumption, and simultaneously improves the extraction rate and activity retention of ginsenosides, becoming an important direction for optimizing current ginsenoside extraction processes.

[0003] To further extract saponin components from ginseng raw materials and reduce waste, industrial production typically employs multiple extraction processes (i.e., repeatedly extracting the same batch of ginseng raw materials) to increase the overall extraction rate. However, traditional multiple extraction processes have significant operational drawbacks: after each extraction, the entire mixture of ginseng residue and saponin extract in the extraction tank must be discharged to external solid-liquid separation equipment (such as plate and frame filter presses, horizontal centrifuges, etc.) for separation; after separation, the resulting ginseng residue filter cake must be manually collected, transported, and returned to the extraction tank; finally, new extraction solvent must be added to the tank before the next extraction cycle can begin. This process is not only cumbersome and time-consuming, but also significantly increases the intensity of manual labor. Utility Model Content

[0004] The main purpose of this invention is to provide an ultrasonic-assisted extraction device for ginsenosides, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a ginsenoside ultrasonic-assisted extraction device, comprising a base, a replacement mechanism installed in the middle of the base, an extraction tank provided on one side of the upper part of the base, a tank cover provided on one side of the output end of the replacement mechanism, a connecting cover provided on the other side of the output end of the replacement mechanism, and a filter press mechanism provided in the middle of the connecting cover. The replacement mechanism includes a support plate, a limiting post, a threaded rod, a first geared motor, a support frame, and a rotating assembly. A can lid is provided on one side of the rotating assembly, and a connecting cover is provided on the other side. The middle of the rotating assembly is rotatably connected to the outer periphery of the support frame. The front and rear sides of the support frame are slidably connected to the outer periphery of the limiting post. The lower end of the limiting post is fixedly connected to the upper part of the base, and the upper end of the limiting post is fixedly connected to the front and rear sides of the lower part of the support plate. The middle of the support frame is threadedly connected to the upper part of the threaded rod, the lower end of the threaded rod is rotatably connected to the middle of the base, and the upper end of the threaded rod is rotatably connected to the middle of the support plate. The first geared motor is mounted on the upper part of the support plate, and its lower output end passes through the support plate and is fixedly connected to the middle of the threaded rod.

[0006] Preferably, the rotating assembly includes an adjusting frame, an internal gear ring, a gear, and a second reduction motor. The middle part of the adjusting frame is rotatably connected to the outer periphery of the support frame. The lower part of the internal gear ring is fixedly connected to the upper side of the middle part of the adjusting frame. The second reduction motor is installed at the lower part of the support frame. The output end of the second reduction motor passes through the support frame and is fixedly connected to the middle part of the gear. The outer periphery of the gear is meshed with the inner side of the internal gear ring. A can lid is connected to the lower part of one side of the adjusting frame via a chain, and a connecting cover is connected to the other side of the adjusting frame via a chain.

The lower end of the drain pipe passes through the piston and the filter press plate.

[0010] Preferably, the drain pipe is connected to the input end of the delivery pump via a pipeline.

[0011] Compared with existing technologies, this utility model has the following advantages: The automatic switching between the "ultrasonic tank cover" and the "pressure filter connection cover" can be achieved through a replacement mechanism (including a geared motor, threaded rod, adjusting frame, gear-internal gear ring, etc.), and the pressure filter mechanism directly completes solid-liquid separation within the extraction tank—without needing to discharge the mixed system outside the tank. The ginseng residue filter cake remaining in the tank after separation is in a loose state and does not require manual removal. Only the addition of new extraction solvent is needed to switch back to the ultrasonic tank cover and start the next extraction, completely eliminating the cumbersome steps of "discharge—external separation—filter cake return to the tank" in traditional processes, significantly reducing operation time and manual intervention.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] like Figure 1-3 As shown, a ginsenoside ultrasound-assisted extraction device includes a base 1, a replacement mechanism 3 installed in the middle of the base 1, an extraction tank 2 provided on one side of the upper part of the base 1, a tank cover 4 provided on one side of the output end of the replacement mechanism 3, a connecting cover 5 provided on the other side of the output end of the replacement mechanism 3, and a pressure filter mechanism 7 provided in the middle of the connecting cover 5.

[0016] In this embodiment, the replacement mechanism 3 includes a support plate 301, a limiting post 302, a threaded rod 303, a reduction motor 304, a support frame 305, and a rotating assembly. A can cover 4 is provided on one side of the rotating assembly, and a connecting cover 5 is provided on the other side. The middle of the rotating assembly is rotatably connected to the outer periphery of the support frame 305. The front and rear sides of the support frame 305 are slidably connected to the outer periphery of the limiting post 302. The lower end of the limiting post 302 is fixedly connected to the upper part of the base 1, and the upper end of the limiting post 302 is fixedly connected to the lower front and rear sides of the support plate 301. The middle of the support frame 305 is threadedly connected to the upper part of the threaded rod 303. The lower end of the threaded rod 303 is rotatably connected to the middle of the base 1, and the upper end of the threaded rod 303 is rotatably connected to the middle of the support plate 301. The reduction motor 304 is installed on the upper part of the support plate 301. The lower output end of the first machine 304 passes through the support plate 301 and is fixedly connected to the middle of the threaded rod 303. The rotating assembly includes an adjusting frame 306, an internal gear ring 307, a gear 308, and a second geared motor 309. The middle part of the adjusting frame 306 is rotatably connected to the outer periphery of the support frame 305. The lower part of the internal gear ring 307 is fixedly connected to the upper side of the middle of the adjusting frame 306. The second geared motor 309 is installed at the lower part of the support frame 305. The output end of the second geared motor 309 passes through the support frame 305 and is fixedly connected to the middle of the gear 308. The outer periphery of the gear 308 is meshed with the inner side of the internal gear ring 307. A tank cover 4 is connected to the lower part of one side of the adjusting frame 306 by a chain. A connecting cover 5 is connected to the other side of the adjusting frame 306 by a chain. An ultrasonic transducer 6 is installed in the middle of the tank cover 4. A discharge valve is provided at the lower part of the extraction tank 2.

[0017] Specifically, firstly, ginseng raw materials and extraction solvent are loaded into the extraction tank 2. Then, the reduction motor 304 installed on the upper part of the support plate 301 in the replacement mechanism 3 is started. Its lower output end passes through the support plate 301 and drives the threaded rod 303 fixedly connected to it to rotate. The lower end of the threaded rod 303 is rotatably connected to the middle of the base 1, and the upper end is rotatably connected to the middle of the support plate 301. Because the middle part of the support frame 305 is threadedly connected to the upper part of the threaded rod 303, and the front and rear sides of the support frame 305 are slidably connected, the lower end is fixed to the upper part of the base 1, and the upper end is fixed. The threaded rod 303, positioned on the outer periphery of the limiting posts 302 on both the front and rear sides of the lower part of the support plate 301, rotates, causing the support frame 305 to descend vertically along the limiting posts 302. This causes the rotating assembly, which is rotatably connected to the outer periphery of the support frame 305 in the middle, to descend synchronously. Finally, the can lid 4, connected by a chain to one side of the adjusting frame 306 in the rotating assembly, is fastened to the top of the extraction tank 2 to achieve a seal. Then, the ultrasonic transducer 6 installed in the middle of the can lid 4 is activated, using ultrasonic waves to accelerate the dissolution of ginsenosides from the raw material into the solvent. After extraction is completed, the speed is reduced. Motor 304 rotates in the reverse direction, causing support frame 305 and tank cover 4 to rise and detach from extraction tank 2. Then, the geared motor 309, installed at the lower part of support frame 305 in the rotating assembly, is activated. Its output end passes through support frame 305 and drives gear 308, which is fixedly connected to it, to rotate. The outer circumference of gear 308 is meshed with the inner side of internal gear ring 307 fixed on the upper side of the middle part of adjusting frame 306, thereby driving adjusting frame 306 to rotate 180° around the outer circumference of support frame 305. This causes the connecting cover 5, connected by a chain on the other side of adjusting frame 306, to rotate to the extraction tank. The extraction tank 2 is positioned directly above the top. Then, the geared motor 304 rotates forward, causing the support frame 305 to descend, allowing the connecting cover 5 to engage with the top of the extraction tank 2. Subsequently, solid-liquid separation is achieved through the filter press 7 in the middle of the connecting cover 5. At the same time, the extract containing ginsenosides is transported to subsequent equipment through the drain pipe 704 of the filter press 7 and the connected transfer pump. Finally, the geared motor 309 rotates in the reverse direction, causing the adjusting frame 306 to reset. The geared motor 304 rotates in the reverse direction, causing the connecting cover 5 to rise and disengage, completing one extraction cycle and preparing for the next extraction.

[0018] In this embodiment, the filter press mechanism 7 includes a cylinder 701, a piston 702, a filter press plate 703, a drain pipe 704, and a filter screen. The filter screen is installed on the lower outer periphery of the filter press plate 703 by a clamp. The upper part of the filter press plate 703 is fixedly connected to the lower part of the piston 702. The middle part of the piston 702 is fixedly connected to the lower output end of the cylinder 701. The cylinder 701 is installed in the middle of the connecting cover 5. The lower end of the drain pipe 704 passes through the piston 702 and the filter press plate 703. The drain pipe 704 is connected to the input end of the delivery pump through a pipe.

[0019] Specifically, the cylinder 701, installed in the middle of the connecting cover 5, is activated. Its lower output end pushes the piston 702, which is fixedly connected to it, to move vertically downward. The filter plate 703, fixed at the lower part of the piston 702, moves downward accordingly. When the filter plate 703 contacts the mixture of "ginseng residue + saponin extract" in the extraction tank 2, the cylinder 701 outputs low pressure, which gently squeezes the mixture through the filter plate 703. This pressure is only used to push the saponin extract through the filter screen fixed by clamps on the lower outer periphery of the filter plate 703, achieving preliminary solid-liquid separation without over-compacting the ginseng residue. The separated extract enters the filter plate 703. Inside the 03, the extract is discharged through the drain pipe 704, which runs through the piston 702 and the filter plate 703 at the lower end. The pump connected to the drain pipe 704 sends the extract to the subsequent processing equipment. Due to the low squeezing pressure, the ginseng residue left in the extraction tank 2 forms a loose filter cake. The extraction solvent can be added back to the extraction tank 2 without removing the residue. Then, the replacement mechanism 3 switches back to the tank cover 4 and starts the ultrasonic transducer 6 to carry out the next ultrasonic extraction. After multiple extractions are completed, the discharge valve at the bottom of the extraction tank 2 is opened, and the loose filter cake can be easily discharged, which effectively simplifies the operation process and improves the total extraction rate of ginsenosides.

[0020] Working principle: First, after loading ginseng raw materials and extraction solvent into extraction tank 2, the geared motor 304 in the replacement mechanism 3 is activated. This drives the threaded rod 303 to rotate, causing the support frame 305, threadedly connected to the threaded rod 303 and guided by the limiting post 302, to descend vertically. This causes the rotating assembly, including the adjusting frame 306, connected to the outer circumference of the support frame 305 to descend synchronously, allowing the tank cover 4, connected to the adjusting frame 306 by a chain on one side, to be fastened to the top of extraction tank 2 for sealing. Next, the ultrasonic transducer 6 in the middle of the tank cover 4 is activated, converting electrical energy into high-frequency mechanical vibration. This vibration disrupts the ginseng cell walls through cavitation and enhances solvent convection, accelerating the dissolution of ginsenosides. After extraction, the geared motor 304 rotates in the opposite direction, causing the support frame 305 to rise and disengage the tank cover 4. Then, the geared motor 309 is activated, driving the gear 308 to rotate. Through the meshing of the gear 308 and the internal gear ring 307, the adjusting frame 306 rotates 180°, causing the chain on the other side of the adjusting frame 306 to... The connecting cover 5 is rotated to the top of the extraction tank 2, and then the geared motor 304 rotates in the forward direction to close and seal the connecting cover 5. Next, the cylinder 701 of the filter pressing mechanism 7 in the middle of the connecting cover 5 is activated, which pushes the piston 702 to lower the filter plate 703. The filter plate 703 uses a filter screen installed by clamps on its lower outer periphery to squeeze the mixture, allowing the ginsenoside-containing extract to pass through the filter screen into the inside of the filter plate 703. The extract is then discharged through the drain pipe 704, which runs through the piston 702 and the filter plate 703. The drain pipe 704 is then transported to subsequent equipment via a pump connected to a pipeline. Finally, after filtration, the cylinder 701 reverses direction to raise the filter plate 703, the geared motor 304 reverses direction to disengage the connecting cover 5, and the geared motor 309 reverses direction to reset the adjusting frame 306. Then, extract is added into the extraction tank 2, and the filter cake is broken with tools. The filtration pressure is relatively low, resulting in a loose filter cake. Multiple extractions are performed to increase the ginsenoside extraction rate.
