Description

Technical Field

[0001] The present invention relates to the technical field of extraction of active ingredients of natural products, and in particular to a pressurized reverse circulation extraction device for extracting active ingredients of natural products and a use method thereof. Background Art

[0002] Natural products, such as herbal plants, contain active ingredients that are one of the important raw materials for the production of products such as medicines or spices. For example, the menthol contained in mint can be used to produce cooling oil or skin care products, and the rose essential oil contained in rose peels can be used to produce cosmetics. The traditional natural product active ingredient extraction process includes cleaning, wall breaking, extraction and purification, which are independent steps and are performed in different equipment. This not only makes the entire extraction process cumbersome and requires a lot of manpower and time costs, but also the materials are easily contaminated by the outside world when switching between steps, affecting the quality of the final extract. For example, when transferring from the cleaning equipment to the wall breaking equipment, the materials may be exposed to impurities in the air. This decentralized operation makes it difficult to achieve efficient and continuous production, and cannot meet the growing demand for natural product extracts in large-scale industrial production.

[0003] Existing extraction devices, such as a pressurized reverse circulation extraction device for active ingredients of natural products provided by publication number CN222150960U, include a crushing box, a sealing plate movably connected to the top of the crushing box, a handle fixedly connected to the upper left side of the sealing plate, and a drive assembly fixedly connected to the front and rear ends of the crushing box; the application drives the transmission rod and the reciprocating screw to rotate by a driving motor, so that the moving block drives the fixed assembly and the crushing roller to roll back and forth inside the crushing box, and rolls the plant material on the filter plate to crush it, and the plant material that is not completely crushed can be further crushed by the crushing roller through filtration of the filter plate; because the application only rolls the natural product by the crushing roller, it cannot achieve effective crushing treatment of the natural product, and the application does not make effective improvements to the subsequent pressurized reverse circulation extraction part, which leads to reduced extraction efficiency of the active ingredients in the natural product and low extraction purity. Summary of the Invention

DETAILED DESCRIPTION

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0024] The inventors have found that the traditional extraction process of active ingredients from natural products requires a lot of manpower and time costs, and when the natural product materials are cleaned and crushed, they may come into contact with impurities in the air, resulting in a decrease in the extraction purity of the natural products; in addition, some existing extraction devices have the problem of being unable to completely crush the natural products, which reduces the extraction efficiency and extraction purity.

[0025] Based on the above findings, the present application proposes a pressurized reverse circulation extraction device for active ingredients of natural products. By designing a cleaning component and arranging a counterweight component at the bottom of the cleaning tank, the cleaning tank filled with cooling water is repeatedly shaken to clean the natural product placed therein, and after resetting, the cleaned natural product is poured into the crushing component for crushing treatment; the crushing component is designed to crush the cleaned natural product by a reciprocating crushing knife, and the natural product sent into the pressurized crushing bin is pressurized and crushed by a supercharger, and the material liquid obtained after the crushing treatment is sent to the extraction component for extraction; the extraction component is designed to heat and distill the material liquid and the extractant in the extraction bin by a heater, so that the active ingredient is converted into steam, and is sucked into the extraction bin through an air fan for condensation extraction; it has the advantages of good extraction effect, high extraction purity and easy use. Example 1:

[0026] See Figures 1-4 The present application discloses a pressurized reverse circulation extraction device for active ingredients of natural products, comprising a first shell 1 and a second shell 2. The entire materials of the first shell 1 and the second shell 2 are metal materials with high strength and strong corrosion resistance. The interior of the first shell 1 can be roughly divided into three cavities, while the interior of the second shell 2 can be roughly divided into two cavities. Among them, a cleaning component 3 for cleaning the natural product is provided in the cavity on one side of the first shell 1, and a crushing component 4 for crushing the cleaned natural product is provided in the cavities of the other two adjacent parts. The two cavities in the second shell 2 are combined with an extraction component 5 for extracting and purifying the material liquid produced by the crushing process.

[0027] See Figure 5 The cleaning assembly 3 includes a cleaning groove 301. In this embodiment, two identical arc-shaped chutes 101 are provided on both sides of the first shell 1. The higher end of the arc-shaped chutes 101 is located near the middle of the first shell 1, and the lower end of the arc-shaped chutes 101 is located near one side of the first shell 1. The cleaning tank 301 is a box structure with a cleaning tank door 3011 on the top. Drain holes are evenly distributed on both sides of the cleaning tank 301 and the cleaning tank door 3011 to facilitate the discharge of cooling water. Sliding shafts that fit into the arc-shaped slide 101 are fixed at the two ends of the cleaning tank 301 without drainage holes. A through hole is provided on the sliding shaft at one end of the cleaning tank 301 close to the second shell 2, and a water pipe 303 is connected to the through hole. A cooling water tank 201 is provided on the top of one side of the second shell 2, and the end of the water pipe 303 away from the cleaning tank 301 is connected to the cooling water tank 201. A cooling water inlet 202 is also provided on the top of the cooling water tank 201 for adding cooling water. In some embodiments, a water pump can be optionally provided in the cooling water tank 201 to input the cooling water in the cooling water tank into the cleaning tank 301 through the water pipe 303; When natural products such as herbs are placed in the cleaning tank 301, cooling water is added to the cleaning tank 301 through the cooling water tank 201. Figure 11 as well as Figure 12 When the weight of the cleaning tank 301 increases, it can slide along the arc-shaped slide 101 on the first shell 1 from the higher end to the lower end, and the cleaning tank 301 can be shaken by the counterweight assembly 302 to clean the natural product. A filter bin 304 is also provided below the lower end of the arc-shaped slide 101. When the cleaning tank 301 shakes, the pollutants attached to the surface of the natural product can be shaken and cleaned by cooling water. The sewage generated by cleaning is discharged through the drainage holes on both sides of the cleaning tank 301 and collected and filtered through the filter bin 304. Example 2:

[0028] See Figure 6 The counterweight assembly 302 includes a counterweight box 3021 provided at the bottom of the cleaning tank 301. A first driving member 3022 is provided on the outer side of the bottom of the counterweight box 3021 by a threaded connection. The first driving member 3022 is a micro rotary motor or motor product, such as the "6mm brush motor reducer" product produced by Dongguan Kehua Precision Industrial Technology Co., Ltd., which can drive the power shaft to rotate in the forward or reverse direction. The first driving member 3022 can be combined with the gear transmission belt structure to drive the push plate 3028 to stir the liquid in the counterweight box 3021, so that the counterweight box 3021 drives the cleaning tank 301 to shake, or the cleaning tank 301 is placed in a horizontal state. The gear transmission belt structure is specifically as follows: a first driving gear 3023 is fixed on the power shaft of the first driving member 3022, and a driven gear 3024 is rotatably provided on one side of the first driving gear 3023 and meshed with it. A first connecting shaft 3025 is fixed to the middle part of the gear surface of the first driving gear 3023 and the driven gear 3024 and away from the counterweight box 3021 by welding or the like. A transmission belt 3026 is respectively sleeved on the two first connecting shafts 3025, and one end of the two transmission belts 3026 extends away from the first connecting shaft 3025 to the two ends of the cleaning tank 301, and is sleeved on the second connecting shaft 3027 rotatably provided near the two ends of the cleaning tank 301. The two second connecting shafts 3027 pass through the counterweight box 3021 and maintain close contact with the connection at the bottom of the counterweight box 3021. One end of the two second connecting shafts 3027 located inside the counterweight box 3021 is fixedly connected to the push plate 3028. See Figure 7 The counterweight box 3021 is internally provided with two counterweight chambers 3029. Each counterweight chamber 3029 is roughly shaped like a cylindrical cavity structure with a cross-section of 3 / 4 circle. The two 3 / 4 cylindrical cavity structures are centrally symmetrically distributed and horizontally arranged in the counterweight box 3021. That is, the two vertical straight plate members at the notches of the two 3 / 4 cylindrical cavity structures are arranged parallel to each other to achieve communication between the two cylindrical cavity structures. The two push plates 3028 are both hingedly arranged at one end of the vertical straight plate of the two cylindrical cavities near the center line, and the movable end of each push plate 3028 is in close contact with the cylindrical inner curved surface of the counterweight chamber 3029, and each push plate 3028 can be rotated to fit with the two vertical straight plate members of the counterweight chamber 3029. When the two push plates 3028 rotate, they can always separate the two counterweight chambers 3029 into three parts. The central part of the three parts of the two counterweight chambers 3029, that is, the cavity formed between the two push plates 3028, is filled with liquid that can just completely fill the central part of the counterweight chamber 3029. When the first driving member 3022 drives the first driving gear 3020 in a periodic forward or reverse direction, the first driving member 3022 can rotate to fit the two vertical straight plate members of the counterweight chamber 3029. When the driven gear 3024 rotates, the first connecting shaft 3025 cooperates with the transmission belt 3026 to drive the two second connecting shafts 3027 to rotate synchronously in opposite directions, thereby driving the two push plates 3028 to rotate synchronously and in opposite directions, so as to push the liquid to flow along the counterweight chamber 3029. When the liquid flows into one of the two counterweight chambers 3029, it can drive the cleaning tank 301 as a whole to tilt toward the side where the counterweight chamber 3029 is located. When the liquid is reciprocated along the two counterweight chambers 3029 under the periodic rotation of the two push plates 3028, the center of gravity of the cleaning tank 301 can be adjusted, causing the cleaning tank 301 to shake, thereby cleaning the natural products placed in the cleaning tank 301. It should be noted that when the two push plates 3028 are controlled to rotate synchronously to Figure 7 The angle shown in the figure, that is, when the two push plates 3028 are both located at the midline of the 3 / 4 circular surface of the counterweight chamber 3029, the two push plates 3028 are parallel to each other, which can keep the liquid filled in the counterweight chamber 3029 balanced on both sides. At this time, the cleaning tank 301 can be kept horizontal as a whole through the balanced state in the counterweight chamber 3029, and can be kept as horizontal as possible when the cleaning tank 301 slides along the arc-shaped slide groove 101. Example 3:

[0029] See Figure 8 as well as Figure 9 , on both sides of the first shell 1, and at the top of the arc-shaped slide 101, a fixed plate is provided, and a second driving member 305 is fixed on the fixed plate by a threaded connection or the like. The model of the second driving member 305 can refer to the first driving member 3022. The power output shaft of the second driving member 305 penetrates the top of the arc-shaped slide 101, and the end of the power output shaft is fixed with a driving wheel 306 located inside the first shell 1. A driven wheel 307 that can fit with the driving wheel 306 is also fixed on the sliding shaft at both ends of the cleaning tank 301. The driving wheel 306 and the driven wheel 307 can both be made of a material with a relatively rough surface and a certain degree of elasticity. When the second driving member 305 is started, the cleaning tank 301 can be rotated by the friction generated by the fit between the driving wheel 306 and the driven wheel 307, thereby dumping the cleaned natural product; The first magnetic member 308 is sleeved on the power output shaft of the second driving member 305, and the first magnetic member 308 is fixed to the outside of the first shell 1 and is located at the top of the arc-shaped slide 101. In addition, the second magnetic member 309 that can be attracted to the first magnetic member 308 is also rotatably provided on the outside of the first shell 1. The first magnetic member 308 and the second magnetic member 309 are attracted by the magnetic surfaces formed by the protrusions and depressions respectively arranged in the middle, that is, the first magnetic member 308 and the second magnetic member 309 are in a horizontal state when attracted, and are located on the arc-shaped slide. An arc-shaped guide groove 102 is provided directly below the groove 101. The second magnetic member 309 is also provided with a shaft structure slidably connected to the arc-shaped guide groove 102. The arc-shaped guide groove 102 has the same curvature as the arc-shaped slide groove 101. The difference is that the arc-shaped guide groove 102 is only provided on the outer wall of the first shell 1, while the arc-shaped slide groove 101 runs through the side wall of the first shell 1. When the second magnetic member 309 moves with the cleaning tank 301, it can always maintain a horizontal state, so that when the cleaning tank 301 is reset upward, it can ensure the magnetic adsorption of the first magnetic member 308 and the second magnetic member 309. In addition, a cleaning tank reset member 310 is fixed to the power output shaft of the second driving member 305 and the sliding shaft of the cleaning tank 301 by means of bolt connection or the like. In this embodiment, the cleaning tank reset member 310 is an elastic band structure of a special polymer material, which has strong elastic force and strong deformation and stretching properties. The initial length of the cleaning tank reset member 310 is relatively short. When the cleaning tank 301 slides downward along the arc-shaped slide groove 101, the cleaning tank reset member 310 can be stretched. When the weight of the cleaning tank 301 is reduced, the cleaning tank 301 can be reset by the cleaning tank reset member 310, and then the driving wheel 306 and the driven wheel 307 are fitted together through the adsorption effect of the first magnetic member 308 and the second magnetic member 309.

[0030] See Figure 13 as well as Figure 16 The cleaning tank 301 is also provided with a clamping component that can only open the cleaning tank door 3011 when the cleaning tank 310 is driven to rotate by the driving wheel 306. The clamping structure includes a clamping member 3012 arranged on the cleaning tank door 3011 away from the rotation connection with the cleaning tank 301. The clamping member 3012 is arranged perpendicular to the cleaning tank door 3011. At the same time, a clamping groove is provided in the side wall of the cleaning tank 301, in which the clamping member 3012 can be clamped. A snap-fit ​​reset member 3013 is provided in the connection slot. When the cleaning tank door 3011 is closed, the snap-fit ​​member 3012 is engaged with the connection slot and presses the snap-fit ​​reset member 3013. A protrusion is provided on the side of the snap-fit ​​member 3012 away from the cleaning tank door 3011. When the snap-fit ​​member 3012 is engaged with the connection slot, the protrusion protrudes along the inner wall of the cleaning tank 301 and secures the cleaning tank door 3011 relative to the cleaning tank 301 via the snap-fit ​​member 3012. A trigger 3014 is provided on the cleaning tank door 3011. In this embodiment, the trigger 3014 is a metal ball connected by a flexible rope 405. When the cleaning tank 310 rotates under the action of the driving wheel 306, the trigger 3014 remains in a vertical downward state. When the cleaning tank 310 continues to rotate until the metal ball on the trigger 3014 contacts the raised structure of the clamping member 3012, the clamping member 3012 can be squeezed away from the cleaning tank 310 until the raised structure of the clamping member 3012 no longer contacts the bottom of the clamping tank. When the cleaning tank 310 is rotated to a certain angle, the trigger 3014 contacts the clamping member 3012, that is, when the cleaning tank 310 is shaken for cleaning under the drive of the counterweight assembly 302, the possibility of the trigger 3014 contacting the clamping member 3012 is extremely small, which can prevent the cleaning tank door 3011 from opening during cleaning and maintain the stability of the device operation.

[0031] In one embodiment, a baffle 103 is rotatably provided on the top of the first shell 1. The baffle 103 is initially arranged horizontally, and its movable end is overlapped on the side of the first shell 1 close to the filter bin 304. When the cleaning tank 301 slides downward, the baffle 103 can be manually flipped so that it is vertically downward to block between the crushing assembly 4 and the cleaning tank 301 to prevent the sewage generated during cleaning from splashing into the crushing assembly 4. When the amount of water in the cleaning tank 301 decreases, the baffle 103 can first generate a certain resistance to the reset of the cleaning tank 301. When the amount of water in the cleaning tank 301 continues to decrease and resets upward, the baffle 103 rotates and resets upward under the action of the cleaning tank 301 until the baffle 103 is close to a flat state to block the top of the cleaning tank 301. Example 4:

[0032] See Figure 10 The crushing assembly 4 can be divided into a mechanical crushing component 401 and a pressurized crushing component 402, wherein the mechanical crushing component 401 includes a mechanical crushing chamber 4011 located in the middle of the first shell 1, that is, directly below the highest point of the arc-shaped chute 101. When the cleaning tank 310 is tilted under the action of the second driving member 305, the cleaned natural product can be poured into the mechanical crushing chamber 4011. A first filter 4014 is provided at the bottom of the mechanical crushing chamber 4011. A crushing knife 4013 is provided near the first filter 4014 at the bottom of the mechanical crushing chamber 4011. The crushing knife 4013 can be rotated by a third driving member 4012 and reciprocated along the mechanical crushing chamber 4011. The model of the third driving member 4012 can refer to the model of the first driving member 4022. The crushing knife 4013 includes a shaft body and a plurality of blades evenly distributed on the shaft body. The shaft body is slidably arranged in a group of horizontally symmetrical crushing knife slots 4018 opened on both sides of the first shell 1. A driving rack 4017 is provided at the bottom of the crushing knife slot 4018 on one side. A second driving gear 4016 is meshed with the driving rack 4017. The power output shaft of the third driving member 4012 is fixed to the second driving gear 4016 and the shaft body of the crushing knife 4013 in sequence. A third driving member guide groove 4019 is also provided above or below the crushing knife slot 4018 and is horizontally arranged and does not pass through the first shell 1. A slider structure is provided which is slidably connected to the guide groove 4019 of the third driving member. When the third driving member 4012 is started in the forward or reverse direction, its power output shaft first drives the crushing knife 4013 to rotate forward or reverse synchronously. At the same time, the second driving gear 4016 is driven by the third driving member 4012 and drives the crushing knife 4013 to move back and forth laterally through the meshing action with the driving rack 4017. Then, the blades on the crushing knife 4013 mechanically crush the natural product. A first storage bin 4015 is provided directly below the first filter screen 4014. After the natural product is crushed and filtered, the generated material liquid flows into the first storage bin 4015. The pressurized crushing component 402 includes a pressurized crushing chamber 4021 adjacent to the mechanical crushing chamber 4011. A supercharger 4022 for pressurizing the interior of the chamber is provided on the top of the pressurized crushing chamber 4021. A second filter screen 4023 is provided at the bottom of the pressurized crushing chamber 4021 and on a side away from the mechanical crushing chamber 4011. A second storage chamber 4024 is provided below the second filter screen 4023. There is also a conveyor belt 4025 between them. The conveyor belt 4025 is a one-way conveyor belt product. A partition 4026 that can be opened by manually pulling the flexible rope 405 is provided adjacent to the bottom of the mechanical crushing chamber 4011 and the pressurized crushing chamber 4021. The partition 4026 is a rectangular structure, and its shortest side is longer than the farthest length of the two sides of the blade on the axis of the crushing knife 4013. When there are natural products in the mechanical crushing chamber 4011 that cannot be crushed by the crushing knife 4013, refer to Figure 14And 15, by manually pulling up the flexible rope 405 to open the partition 4026, the crushing knife 4013 can move along the mechanical crushing chamber 4011, and can drive the natural product to the conveyor belt 4025, and transport it to the pressurized crushing chamber 4021 through the conveyor belt 4025. At this time, the partition 4026 is closed, and the supercharger 4022 is started. The natural product in the pressurized crushing chamber 4021 is crushed by the pressurized action, and the material liquid produced by the crushing flows into the second storage chamber 4024. A pressure relief valve 4027 is provided at the top of the pressurized crushing chamber 4021. After the crushing is completed, the pressure relief valve 4027 can be opened to restore the pressure in the pressurized crushing chamber 4021 to its initial state.

[0033] The bottom of the first storage bin 4015 and the bottom of the second storage bin 4024 are connected to the extraction end of the extraction pump 403 through the delivery pipe 404, and the output end of the extraction pump 403 is connected to the extraction component 5 arranged in the second shell 2 through the delivery pipe 404, so as to pump the material liquid collected in the first storage bin 4015 and the second storage bin 4024 into the extraction component 5 for extraction and purification; in addition, a filter 406 can also be set on the delivery pipe 404 to filter out impurities in the material liquid. Embodiment 5:

[0034] See Figure 17 The extraction component 5 includes an extraction chamber 501 arranged in the second shell 2 and away from the cooling water tank 201. The output end of the extraction pump 403 for delivery is connected to one side of the extraction chamber 501 through the delivery pipe 404. An extractant injection port 502 is provided at the top of the extraction chamber 501. An extractant that improves the purification effect can be added through the extractant injection port 502. The specific type of extractant can be selected according to the type of natural active product and will not be described here. A heating element 503 is provided at the bottom of the extraction chamber 501. The heating element 503 is a heating plate product, such as the "epoxy heating plate" product produced by Shenzhen Fulianda Electric Heating Appliance Co., Ltd. When the material liquid is extracted, it can be heated by the heating element 503, while improving the extraction efficiency, so that the extracted natural active ingredients are converted into steam and diffused upward; See Figure 18, is located in the second shell 2, and is provided with an extraction chamber 505 directly below the cooling water tank 201. At the same time, an air fan 506 is provided near the top of the extraction chamber 501 and is connected to the extraction chamber 505. The air fan 506 is a unidirectionally driven air fan structure driven by a motor. When the steam containing natural active ingredients in the extraction chamber 501 diffuses upward, the steam can be pumped into the extraction chamber 505 by the air fan 506. At this time, the steam contacts the bottom of the cooling water tank 201 and is converted into a liquid containing natural active ingredients and drips into the extraction chamber 505. An extract discharge port 507 is provided at the bottom of the extraction chamber 505. By opening the extract discharge port 507, the natural active ingredient liquid purified by distillation can be collected. A waste liquid discharge port 504 is also provided at the bottom of the extraction chamber 501 to discharge the waste liquid generated after the material liquid is purified.

[0035] A method for using a pressurized reverse circulation extraction device for extracting active ingredients from natural products comprises the following steps: S1. Place the natural product into the cleaning tank 301 and add cooling water to the cleaning tank 301 through the cooling water tank 201, so that the cleaning tank 301 increases in weight and slides downward along the arc-shaped slide groove 101 on the first housing 1; S2. Start the first driving member 3022, and use the two push plates 3028 to periodically reciprocate, pushing the liquid in the counterweight chamber 3029 to repeatedly move to both sides, causing the center of gravity to change, so that the cleaning tank 301 shakes to clean the natural product; S3: The cooling water in the cleaning tank 301 overflows due to the shaking action. After the weight of the cleaning tank 301 is reduced, it is reset upward along the arc-shaped slide 101 under the action of the cleaning tank reset member 310 until the first magnetic member 308 and the second magnetic member 309 are attracted. At this time, the second driving member 305 is activated, and the driven rotating wheel 307 is driven to rotate by the driving wheel 306, so that the cleaning tank 301 is tilted and the cleaned natural product is poured into the mechanical crushing chamber 4011; S4. Start the third driving member 4012 to mechanically crush the natural product with the crushing blade 4013. Then, open the partition 4026 to send the natural product that cannot be crushed by the crushing blade 4013 into the pressurized crushing chamber 4021 for pressurized crushing. S5. Turn on the extraction pump 403 to pump the material liquid collected in the first storage bin 4015 and the second storage bin 4024 into the extraction bin 501 for heating and extraction, and then pump it to the extraction bin 505 for extraction through the air fan 506.

[0036] Practical application cases Open the cooling water inlet 202 to add cooling water to the cooling water tank 201, open the cleaning tank door 3011, place the natural product for extracting the active ingredient into the cleaning tank 301, and close the cleaning tank door 3011. Then, add cooling water for cleaning to the cleaning tank 301 through the cooling water tank 201. In this case, mint leaves are used as the natural product raw material for extracting the active ingredient. After the weight of the cleaning tank 301 increases, it slides down along the arc-shaped slide 101. When the cleaning tank 301 slides down to contact the bottom of the arc-shaped slide 101, the baffle 103 is manually flipped, and then the first driving member 3022 is turned on to make the cleaning tank 301 shake to clean the mint leaves. The washed sewage in the washing tank 301 is discharged from the drain hole under the action of shaking. As the weight of the washing tank 301 decreases, it gradually returns to its original position under the elastic force of the washing tank reset member 310 until the driven runner 307 fits into the driving runner 306. At this time, the second driving member 305 is turned on, and the friction between the driving runner 306 and the driven runner 307 causes the washing tank 301 to rotate until the washing tank door 3011 opens, and the washed mint leaves are dumped into the mechanical crushing chamber 4011. The third driving member 4012 is turned on to drive the crushing blade 4013 to rotate. At the same time, the crushing blade 4013 is driven to move laterally through the meshing action of the gear rack to mechanically crush the mint leaves. For the mint leaves that cannot be mechanically crushed by the crushing blade 4013, the conveyor belt 4025 is turned on and the partition 4026 is opened, so that the crushing blade 4013 can send the mint leaves into the pressurized crushing chamber 4021 for pressurized crushing. The extraction pump 403 is turned on to pump the material liquid collected in the first storage bin 4015 and the second storage bin 4024 into the extraction bin 501. The heating element 503 is turned on and an extractant is added. In this case, the extractant used is ethanol or ether. Such solvents have a strong affinity for menthol and the solution itself is easily volatile. Therefore, they can be used to extract the active ingredient containing menthol from the material liquid. After heating, the active ingredient and the extractant in the material liquid diffuse upward in a vapor state and are sent to the extraction bin 505 by the air fan 506 for condensation extraction to obtain the final active ingredient extract.

[0037] It should be noted that, in addition to being applicable to mint leaves as described above, the present application can also be applied to: extracting rose essential oil from rose petals, extracting lavender oil from lavender, extracting clove oil from clove buds, extracting limonene from citrus peels, extracting cinnamaldehyde from cinnamon, and other natural products for active ingredient extraction. The device provided by the technical solution of the present invention can be applied to the extraction of active ingredients from various natural products mentioned above. The difference is that in the extraction step, an appropriate extractant should be added according to the type of natural product.

Those skilled in the art should understand that the present invention is not limited to the foregoing embodiments. The foregoing embodiments and descriptions are merely illustrative of the principles of the present invention.
