Description

Technical Field

[0001] This invention belongs to the field of essential oil extraction technology, specifically a process and apparatus for extracting Polygonum hydropiper essential oil. Background Technology

[0002] Melanin is the primary pigment responsible for pigmentation in the skin, hair, and eyes. Melanocytes produce melanin. The development of melanoma and skin pigmentation are important photoprotective factors, protecting against damage from ultraviolet radiation and the risk of skin cancer. Abnormal shedding of melanoma and pigmentation can be serious problems for facial aesthetics and skin diseases. Water pepper (Polygonum hydropiper) is an annual herb belonging to the Polygonaceae family and the Polygonum genus, distributed throughout the provinces of China. It has been reported that the whole plant of water pepper is used medicinally for its anti-inflammatory, detoxifying, diuretic, and anti-diarrheal properties.

[0003] A Chinese patent with publication number CN108676624A discloses a method for extracting rose essential oil and the rose essential oil itself, belonging to the field of rose essential oil extraction technology. The extraction method includes the following steps: A. Raw material processing: adding fresh rose petals into a distillation vessel; B. Steam distillation: introducing steam into the distillation vessel in a vertically multi-layered, spaced-apart manner to cause the rose petals to undergo turbulent distillation, controlling and adjusting the temperature of the condensate outlet, and controlling and adjusting the distillation time; C. Separation: separating the oil-water mixture generated in the distillation vessel through a condenser and then in a separator to collect the rose essential oil. This invention can solve the technical problem in the prior art where rose petals easily stick together in layers during the steaming process, leading to insufficient and uneven steaming, and can achieve the technical effect of improving the oil yield and quality of rose essential oil.

[0004] When distilling Polygonum hydropiper powder, the finer the powder is ground, the larger the contact area between the powder and water will be, and the water will be more evenly dispersed. This makes it easier for the broken oil cells to burst and increase the oil yield. However, if the powder is too fine, it will not be easy for air to pass through during distillation, and the powder will be more prone to stickiness, which will affect the oil yield.

[0005] Therefore, the present invention provides a process and apparatus for extracting Polygonum hydropiper essential oil. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: The extraction process of this invention includes the following steps:

[0008] S1: Clean the water pepper, air dry the surface of the water pepper, then cut and crush it to make water pepper powder;

[0009] S2: Soak the water pepper powder in clean water, stir evenly, and then filter to obtain moist water pepper powder;

[0010] S3: Add the moistened Polygonum hydropiper powder into the extraction device, heat it to generate steam, and let the Polygonum hydropiper essential oil and steam flow out through the conduit;

[0011] S4: The steam is cooled into a liquid, and the water pepper essential oil is separated according to the specific gravity of water and essential oil.

[0012] An extraction apparatus for Polygonum hydropiper essential oil is disclosed. This apparatus is suitable for the aforementioned extraction process of Polygonum hydropiper essential oil. The extraction apparatus includes a tank, a water inlet pipe, a heater, a partition, and steaming frames. The water inlet pipe is connected to one side of the bottom of the tank. A heater is installed at the bottom of the tank. A partition is fixedly connected to the bottom of the tank. Multiple through slots are formed around the center of the partition. Multiple steaming frames are stacked on the top surface of the partition. The outer wall of each steaming frame slides against the inner wall of the tank. Polygonum hydropiper powder is evenly placed inside each steaming frame. During operation, clean water is added to the bottom of the tank through the water inlet pipe. The heater heats the water to generate steam. The Polygonum hydropiper powder is evenly dispersed inside the multiple steaming frames. The steam passes through the Polygonum hydropiper powder, extracting the essential oil. Using multiple steaming frames reduces the probability of the Polygonum hydropiper powder becoming sticky, thereby improving the extraction efficiency of the Polygonum hydropiper essential oil.

[0013] Preferably, a first rotating rod is rotatably mounted in the middle of the partition, and a fan blade is fixedly connected to the bottom end of the first rotating rod. A second rotating rod is rotatably mounted in the middle of the steaming frame. Both the first and second rotating rods have a cross-shaped circular hole at their top center. A cross-shaped fixing rod is fixedly connected to the bottom center of the second rotating rod, and the outer wall of the cross-shaped fixing rod slides in fit with the inner wall of the cross-shaped circular hole. Multiple horizontal bars are arranged around the middle outer ring of the second rotating rod, and the bottom surface of the horizontal bars slides in fit with the inner bottom surface of the steaming frame. The inner surface of the tank... Multiple guide strips are fixed to the wall, and the outer wall of the guide strips slides in conjunction with the outer groove of the steaming frame. During operation, the steaming frame is placed into the interior of the tank along the guide strips. The guide strips restrict the position of the steaming frame and prevent it from rotating. When the steam passes through the partition and then through the fan blades, it drives the fan blades to rotate, which in turn drives the first rotating rod to rotate, which in turn drives the connected second rotating rod to rotate. This causes the crossbar to slide against the bottom wall of the steaming frame, scraping up the water pepper powder and dispersing it, thereby further reducing the probability of the water pepper powder becoming sticky.

[0014] Preferably, the bottom surface of the crossbar is provided with multiple arc-shaped grooves, and the bottom surface of the side wall of the arc-shaped groove slides in cooperation with the inner bottom surface of the steaming frame. During operation, when the crossbar slides over the bottom wall of the steaming frame, the water pepper powder is divided by the side wall of the arc-shaped groove. At the same time, it reduces the probability of the water pepper powder being pushed and agglomerated by the crossbar, further improving the dispersion of the water pepper powder and improving the rising efficiency of water vapor.

[0015] Preferably, multiple elastic rods are fixed to both sides of the crossbar, and a steel ball is fixed to the other end of each elastic rod. The outer wall of the steel ball slides in contact with the inner bottom surface of the steaming frame. During operation, when the crossbar rotates, it drives the elastic rods to move, causing the steel ball to slide against the bottom wall of the steaming frame, which in turn causes the elastic rods to bend. When the elastic force of the bending of the elastic rod is greater than the resistance experienced by the steel ball, the elastic rod springs back to its original position, causing the steel ball to strike the bottom wall of the steaming frame. This shakes up the water pepper powder adhering to the bottom wall of the steaming frame, reducing the probability of the water pepper powder sticking together. At the same time, the steel ball strikes the crossbar under the elastic force of the elastic rod, causing the crossbar to vibrate, which further reduces the probability of water pepper powder adhering to the surface of the crossbar.

[0016] Preferably, an elastic shovel is fixedly connected inside the arc-shaped groove, the bottom surface of the elastic shovel slides in contact with the inner bottom surface of the steaming frame, and a flipping seat is fixedly connected to the top surface of the elastic shovel. Arc grooves are provided on both sides of the flipping seat. During operation, the Polygonum hydropiper powder passes through the inside of the arc-shaped groove. The Polygonum hydropiper powder is scooped up by the elastic shovel, divided by the flipping seat, and rotated and turned over by the arc groove, thus piling up the Polygonum hydropiper powder, thereby further improving the extraction efficiency of Polygonum hydropiper essential oil.

[0017] Preferably, a connecting rod is fixedly connected to the outer ring of the middle part of the second rotating rod, and the other end of the connecting rod is fixedly connected to one end of the crossbar. An arc-shaped push plate is fixedly connected to the side of the connecting rod near the crossbar, and the bottom surface of the arc-shaped push plate slides in cooperation with the inner bottom surface of the steaming frame. During operation, when the first rotating rod rotates, it drives the arc-shaped push plate to rotate, pushing the water pepper powder that has moved to the middle of the steaming frame to the outer ring, thereby further improving the dispersion of the water pepper powder and reducing the probability of water pepper powder agglomeration.

[0018] Preferably, the bottom surface of the steaming frame is provided with an annular groove, and an elastic filter plate is bolted inside the annular groove. The top surface of the elastic filter plate slides in conjunction with the bottom surface of the crossbar. During operation, when the crossbar rotates, the bottom surface of the crossbar presses against the elastic filter plate, causing the elastic filter plate to bend downwards in a localized area. After the crossbar slides past, the elastic filter plate returns to its original position, shaking up the water pepper powder on the top surface of the elastic filter plate, thereby improving the dispersion of the water pepper powder. At the same time, the annular groove increases the concentration of water vapor, thereby improving the degree of essential oil extraction from the water pepper powder by the water vapor.

[0019] Preferably, the bottom surface of the elastic filter plate and the bottom surface of the annular groove are both fixedly connected to multiple conical seats. Each conical seat has an internal cavity, and a sliding rod is slidably installed between the two cavities. Multiple elastic strips are fixedly connected to both ends of the sliding rod, and the outer wall of each elastic strip slides in cooperation with the inner wall of the cavity. During operation, the bottom surface of the crossbar presses against the elastic filter plate, causing a localized downward bend in the elastic filter plate. This brings the two conical seats closer together, allowing the sliding rod to slide into the cavity, causing the elastic strips to bend and slide. When the elastic filter plate resets, the elastic strips also reset, further increasing the reset force of the elastic filter plate and thus further enhancing the strength of shaking up the water pepper powder.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. The present invention discloses an extraction process and apparatus for Polygonum hydropiper essential oil, comprising a tank, a water inlet pipe, a heater, a partition, and steaming frames; clean water is added to the bottom of the tank through the water inlet pipe, the heater heats the water to generate steam, and Polygonum hydropiper powder is evenly dispersed inside multiple steaming frames. The steam passes through the Polygonum hydropiper powder, extracting the essential oil. The multiple steaming frames reduce the probability of the Polygonum hydropiper powder becoming sticky, thereby improving the extraction efficiency of Polygonum hydropiper essential oil.

[0022] 2. The extraction process and apparatus for Polygonum hydropiper essential oil of the present invention, by setting up fan blades, a first rotating rod, a second rotating rod, and a crossbar; when water vapor passes through the partition, the water vapor passes through the fan blades, driving the fan blades to rotate, driving the first rotating rod to rotate, driving the connected second rotating rod to rotate, and driving the crossbar to slide against the bottom wall of the steaming frame, scraping up the Polygonum hydropiper powder and dispersing the Polygonum hydropiper powder, thereby further reducing the probability of the Polygonum hydropiper powder becoming sticky.

[0034] 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.

[0035] Example 1

[0036] like Figure 9 As shown in the embodiment of the present invention, an extraction process for Polygonum hydropiper essential oil includes the following steps:

[0037] S1: Clean the water pepper, air dry the surface of the water pepper, then cut and crush it to make water pepper powder;

[0038] S2: Soak the water pepper powder in clean water, stir evenly, and then filter to obtain moist water pepper powder;

[0039] S3: Add the moistened Polygonum hydropiper powder into the extraction device, heat it to generate steam, and let the Polygonum hydropiper essential oil and steam flow out through the conduit;

[0040] S4: The steam is cooled into a liquid, and the water pepper essential oil is separated according to the specific gravity of water and essential oil.

[0041] like Figures 1 to 2 As shown, an extraction device for Polygonum hydropiper essential oil is disclosed. This extraction device is suitable for the above-mentioned extraction process of Polygonum hydropiper essential oil. The extraction device includes a tank body 1, a water inlet pipe 2, a heater 3, a partition 4, and steaming frames 5. The bottom of the tank body 1 is connected to the water inlet pipe 2. The heater 3 is installed at the bottom of the tank body 1. The partition 4 is fixed to the bottom of the tank body 1. Multiple through grooves are formed around the middle of the partition 4. Multiple steaming frames 5 are stacked on the top surface of the partition 4. The outer wall of the steaming frame 5 slides against the inner wall of the tank body 1. Polygonum hydropiper powder is evenly placed inside the steaming frame 5. During operation, clean water is added to the bottom of the tank body 1 through the water inlet pipe 2. The heater 3 heats the clean water to generate steam. The Polygonum hydropiper powder is evenly dispersed inside the multiple steaming frames 5. The steam passes through the Polygonum hydropiper powder and extracts the essential oil. By using multiple steaming frames 5, the probability of the Polygonum hydropiper powder becoming sticky is reduced, thereby improving the extraction efficiency of Polygonum hydropiper essential oil.

[0042] like Figures 2 to 4 As shown, a first rotating rod 6 is rotatably installed in the middle of the partition 4, and a fan blade 7 is fixedly connected to the bottom end of the first rotating rod 6. A second rotating rod 8 is rotatably installed in the middle of the steaming frame 5. A cross-shaped circular hole 9 is opened in the middle of the top of both the first rotating rod 6 and the second rotating rod 8. A cross-shaped fixing rod 10 is fixedly connected to the middle of the bottom end of the second rotating rod 8. The outer wall of the cross-shaped fixing rod 10 slides in fit with the inner wall of the cross-shaped circular hole 9. Multiple horizontal bars 11 are arranged on the outer ring of the middle of the second rotating rod 8. The bottom surface of the horizontal bars 11 slides in fit with the inner bottom surface of the steaming frame 5. The inner surface of the tank 1... Multiple guide strips 12 are fixed to the wall, and the outer wall of the guide strips 12 slides in conjunction with the outer groove of the steaming frame 5. During operation, the steaming frame 5 is placed into the interior of the tank 1 along the guide strips 12. The guide strips 12 restrict the position of the steaming frame 5 and prevent the steaming frame 5 from rotating. When the steam passes through the partition 4 and the fan blades 7, the steam drives the fan blades 7 to rotate, which drives the first rotating rod 6 to rotate, which drives the connected second rotating rod 8 to rotate, which drives the crossbar 11 to slide against the bottom wall of the steaming frame 5, scraping up the water pepper powder and dispersing the water pepper powder, thereby further reducing the probability of the water pepper powder becoming sticky.

[0043] like Figure 5 As shown, the bottom surface of the crossbar 11 is provided with multiple arc-shaped grooves 13, and the bottom surface of the side wall of the arc-shaped groove 13 slides in cooperation with the inner bottom surface of the steaming frame 5. During operation, when the crossbar 11 slides over the bottom wall of the steaming frame 5, the water pepper powder is divided by the side wall of the arc-shaped groove 13. At the same time, it reduces the probability of the water pepper powder being pushed and agglomerated by the crossbar 11, further improving the dispersion of the water pepper powder and improving the rising efficiency of water vapor.

[0044] Multiple elastic rods 14 are fixed to both sides of the crossbar 11. A steel ball 15 is fixed to the other end of each elastic rod 14. The outer wall of the steel ball 15 slides against the inner bottom surface of the steaming frame 5. During operation, when the crossbar 11 rotates, it drives the elastic rods 14 to move, causing the steel ball 15 to slide against the bottom wall of the steaming frame 5, which causes the elastic rod 14 to bend. When the elastic force of the elastic rod 14 is greater than the resistance of the steel ball 15, the elastic rod 14 bounces back to its original position, causing the steel ball 15 to hit the bottom wall of the steaming frame 5, shaking off the water pepper powder adhering to the bottom wall of the steaming frame 5, reducing the probability of water pepper powder sticking together. At the same time, the steel ball 15 hits the crossbar 11 under the elastic force of the elastic rod 14, causing the crossbar 11 to vibrate, reducing the probability of water pepper powder adhering to the surface of the crossbar 11.

[0045] like Figures 5 to 6As shown, an elastic shovel 16 is fixedly connected inside the arc-shaped groove 13. The bottom surface of the elastic shovel 16 slides in conjunction with the bottom surface of the steaming frame 5. A flipping seat 17 is fixedly connected to the top surface of the elastic shovel 16. Arc grooves 18 are provided on both sides of the flipping seat 17. During operation, the water pepper powder passes through the inside of the arc-shaped groove 13. The water pepper powder is scooped up by the elastic shovel 16, divided by the flipping seat 17, and rotated and turned over by the arc grooves 18, thus turning the water pepper powder over and piling it up, thereby further improving the extraction efficiency of water pepper essential oil.

[0046] like Figures 3 to 4 As shown, a connecting rod 19 is fixedly connected to the outer ring of the middle part of the second rotating rod 8. The other end of the connecting rod 19 is fixedly connected to one end of the crossbar 11. An arc-shaped push plate 20 is fixedly connected to the side of the connecting rod 19 near the crossbar 11. The bottom surface of the arc-shaped push plate 20 slides in cooperation with the inner bottom surface of the steaming frame 5. During operation, when the first rotating rod 6 rotates, it drives the arc-shaped push plate 20 to rotate, pushing the water pepper powder that has moved to the middle of the steaming frame 5 to the outer ring, thereby further improving the dispersion of the water pepper powder and reducing the probability of water pepper powder agglomeration.

[0047] like Figure 4 As shown, the bottom surface of the steaming frame 5 is provided with an annular groove 21, and an elastic filter plate 22 is bolted inside the annular groove 21. The top surface of the elastic filter plate 22 is slidably engaged with the bottom surface of the crossbar 11. During operation, when the crossbar 11 rotates, the bottom surface of the crossbar 11 presses against the elastic filter plate 22, causing the elastic filter plate 22 to bend downwards in a localized area. After the crossbar 11 slides past, the elastic filter plate 22 returns to its original position, shaking up the water pepper powder on the top surface of the elastic filter plate 22, thereby improving the dispersion of the water pepper powder. At the same time, the annular groove 21 increases the concentration of water vapor, thereby improving the degree of essential oil extraction from the water pepper powder by the water vapor.

[0048] like Figure 7 As shown, the bottom surface of the elastic filter plate 22 and the bottom surface of the annular groove 21 are both fixedly connected to multiple conical seats 23. The cone seats 23 have cavities 24 inside. A sliding rod 25 is slidably installed between the cavities 24 on both sides. Multiple elastic strips 26 are fixedly connected around both ends of the sliding rod 25. The outer wall of the elastic strips 26 slides in cooperation with the inner wall of the cavity 24. During operation, the bottom surface of the crossbar 11 presses the elastic filter plate 22, causing the elastic filter plate 22 to bend downward locally, bringing the cone seats 23 on both sides closer together. This causes the sliding rod 25 to slide into the cavity 24, causing the elastic strips 26 to bend and slide. When the elastic filter plate 22 resets, the elastic strips 26 also reset, further increasing the reset force of the elastic filter plate 22, thereby further improving the strength of shaking up the water pepper powder.

[0049] Example 2

[0050] like Figure 8As shown in the comparative embodiment one, another embodiment of the present invention is as follows: an elastic sealing sleeve 27 is fixed between the two conical seats 23, and the inner ring of the elastic sealing sleeve 27 is fitted around the outer ring of the slide rod 25; the elastic sealing sleeve 27 blocks external water vapor from entering the cavity 24, reducing the probability of corrosion of the elastic strip 26, thereby improving the service life of the elastic strip 26.

[0051] During operation: the water pepper powder is evenly spread inside the steaming frame 5, the steaming frame 5 is placed inside the tank 1 along the guide bar 12, the guide bar 12 restricts the position of the steaming frame 5, so that the cross fixing rod 10 is inserted into the cross round hole 9, so that multiple steaming frames 5 are stacked in sequence, the water inlet pipe 2 adds clean water to the bottom of the tank 1, and the heater 3 heats the clean water to generate water steam.

[0052] When steam passes through partition 4 and then through fan blade 7, it drives fan blade 7 to rotate, causing first rotating rod 6 to rotate, which in turn drives connected second rotating rod 8 to rotate. This causes crossbar 11 to slide against the bottom wall of steaming frame 5. Water pepper powder is divided by the side wall of arc-shaped groove 13. Water pepper powder passes through the interior of arc-shaped groove 13 and is scooped up by elastic shovel 16. It is then divided by flipping seat 17, and the water pepper powder is turned upside down by arc groove 18, thus turning the water pepper powder over. At the same time, crossbar 11 drives the elastic shovel 16 to rotate. The movement of the elastic rod 14 causes the steel ball 15 to slide against the bottom wall of the steaming frame 5, causing the elastic rod 14 to bend. When the elastic force of the elastic rod 14 is greater than the resistance of the steel ball 15, the elastic rod 14 bounces back to its original position, causing the steel ball 15 to hit the bottom wall of the steaming frame 5 and shake up the water pepper powder adhering to the bottom wall of the steaming frame 5. At the same time, the steel ball 15 hits the crossbar 11 under the elastic force of the elastic rod 14, causing the crossbar 11 to vibrate and reducing the probability of water pepper powder adhering to the surface of the crossbar 11.

[0053] The bottom surface of the crossbar 11 presses against the elastic filter plate 22, causing the elastic filter plate 22 to bend downwards in a localized area. The cone seats 23 on both sides approach each other, causing the slide bar 25 to slide into the cavity 24. This causes the elastic strip 26 to bend and slide. After the crossbar 11 has slid past, the elastic strip 26 returns to its original position, and the elastic filter plate 22 returns to its original position. This shakes up the water pepper powder on the top surface of the elastic filter plate 22, improving the dispersion of the water pepper powder and reducing the probability of the water pepper powder becoming sticky, thereby improving the extraction efficiency of water pepper essential oil.
