Description

Technical Field

[0001] This invention relates to the field of plant essential oil extraction devices, and more particularly to a natural plant extraction device and extraction method. Background Technology

[0002] Plant essential oils, also known as volatile oils or aromatic oils, are fragrant, oily liquids derived from the flowers, buds, leaves, branches, roots, bark, fruits, seeds, and resins of herbaceous plants, and are often referred to as "liquid gold." Currently, the extraction of plant essential oils typically involves pressing the plant material using a pressing device to break it down and extract the juice. This juice is then filtered and separated to extract the essential oils. While pressing involves using a cutting device to cut open the oil sacs in the fruit peel before pressing, the dense and small size of these oil sacs in the peel results in a low extraction rate.

[0003] In existing technologies, a transmission mechanism drives the pressing block to reciprocate up and down, causing the needles at the bottom of the pressing block to continuously puncture the material below the filter cylinder, breaking the oil sacs in the material. Alternatively, a rotating shaft drives a cutting blade to cut the plant material, breaking the oil sacs within. However, these methods lack the cutting, layering, and turning operations of the pressed and compacted plant material, failing to expose the different layers and obscured oil sacs, thus reducing the extraction efficiency of essential oils. Furthermore, using a transmission assembly to rotate the screen plate and turn the plant material over results in the entire plant material being turned over, failing to expose the internal oil sacs and further reducing the extraction efficiency of essential oils. Summary of the Invention

[0004] The purpose of this invention is to solve the problem in the prior art that the plant raw materials after pressing and compaction lack cutting, layering and turning operations, which cannot expose the different layers and the oil sacs that are covered, thus reducing the extraction efficiency of essential oils. Therefore, a natural plant extraction device and extraction method are proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a natural plant extraction device, comprising a circular track, and further comprising: Pressing barrels, multiple pressing barrels can be movably connected on a circular track, and a movable mesh plate is connected inside the pressing barrel, with plant raw materials placed on top of the mesh plate; A pressing mechanism is used to press plant material inside a pressing barrel on a circular track; The extraction mechanism cooperates with another pressing barrel on a circular track and includes a pressing component, a telescopic rotating component, a fixing component, and a cutting component. The telescopic rotating component clamps multiple annular components, and the fixing component clamps the multiple annular components after they move downward. After the screen moves upward, it forms a processing space with the output end of the pressing component and the inner side of the multiple annular components.

A mounting housing is fixedly connected to the side of the first arc-shaped block away from the separator ring. The mounting housing and the side opposite to the second arc-shaped block are clamped and engaged with the clamping block and the first mounting block, and are magnetically engaged with the second electromagnet. A small fan is installed inside the separator ring, and a through-hole is opened in the middle. The air extraction end of the small fan adsorbs the corresponding gauze through the negative pressure at the top and bottom of the through-hole.

[0012] In the above-mentioned natural plant extraction device, the first arc-shaped block and the second arc-shaped block are both provided with cutting grooves for the blade to slide. Two adjacent cutting grooves are located at the top and bottom of the separator ring, respectively. Telescopic devices are installed at both ends of the blade.

A sponge is fixedly connected inside the clamping pad. A slanted groove is opened on the top of the blade, with the bottom end of the slanted groove facing the blade edge.

[0013] In the aforementioned natural plant extraction device, the drive assembly includes two drive motors mounted on a second mounting frame. The output ends of the drive motors are coaxially and fixedly connected to lead screws. The lead screws are rotatably connected between the two second mounting frames.

[0015] Compared with existing technologies, the advantages of this invention are: 1. This invention employs a pressing mechanism and an extraction mechanism. The pressing mechanism performs initial pressing on the orange peel inside the pressing barrel. The extraction mechanism uses a squeezing component and multiple ring components to surround and limit the orange peel lifted by the mesh plate. Then, a cutting component cuts and layers the orange peel. Next, a telescopic rotating component drives different numbers of ring components to rotate, causing the different layers of orange peel to flip over. This flips over the orange peel, exposing more of the oil sacs in the orange peel that were originally in different layers and partially obscured. Then, the cutting component resets and cuts the orange peel, and the pressing mechanism further presses the cut, layered, and flipped orange peel, improving the extraction effect of essential oils from the orange peel. The cutting component, using blades and gauze, simultaneously layers the orange peel while cutting it and can directly perform subsequent flipping operations, improving processing efficiency.

[0016] 2. This invention features a cutting component where the blade moves and engages with a clamping pad, facilitating the tension of the gauze. Two layers of gauze bind the cut and layered orange peel, reducing friction while providing sufficient support to ensure the peel remains intact during the flipping process. A small fan, operating through the upper and lower openings, applies negative pressure to the upper and lower gauze, improving the stability of the gauze support and enabling rapid and stable flipping of the cut and layered orange peel, thus increasing the efficiency of essential oil extraction.

Detailed Implementation

[0019] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0020] Reference Figure 1 and Figure 2A natural plant extraction device, including a circular track 2, and further comprising: Pressing barrels 4, multiple pressing barrels 4 can be movably connected to circular tracks 2, and movable mesh plates 12 are connected inside the pressing barrels 4, with plant raw materials placed on top of the mesh plates 12.

[0021] The pressing barrel 4 is moved on the circular track 2 by the existing moving mechanism, so that it can be moved to different positions for corresponding processing.

[0022] A mesh basket 11 is fixedly connected inside the pressing barrel 4, and a mesh plate 12 is slidably connected inside the mesh basket 11. A discharge pipe is connected to the bottom of the pressing barrel 4, and a discharge valve is installed on the discharge pipe.

[0023] The discharge of the pressing liquid is controlled by the discharge pipe and discharge valve, and the pressing liquid is initially filtered by the mesh basket 11.

[0024] The pressing mechanism is used to press the plant material inside a pressing barrel 4 on a circular track 2.

[0025] The pressing mechanism includes a fixed frame 1, a lifting device is installed on the top of the fixed frame 1, and a pressing head 3 is fixedly connected to the output end of the lifting device. After the pressing head 3 moves downward, it squeezes the plant material inside a pressing barrel 4.

[0026] The lifting device uses existing technology to control the up and down movement of the pressing head 3 to complete the pressing operation.

[0027] Reference Figures 3-6 The extraction mechanism cooperates with another pressing barrel 4 on the circular track 2 and includes a squeezing component, a telescopic rotating component, a fixing component, and a cutting component. The telescopic rotating component clamps multiple annular components, and the fixing component is used to clamp multiple annular components after they move downward. After the screen plate 12 moves upward, it forms a processing space with the output end of the squeezing component and the inner side of multiple annular components. The cutting component includes a cutting element slidably connected to the annular component and a driving component mounted on the fixing component. The output end of the driving component is magnetically engaged with multiple cutting elements. The cutting element includes a blade 31 and a gauze 32 fixedly connected to the back of the blade 31. A roller is rotatably connected inside the annular component, and the end of the gauze 32 away from the blade 31 is wound onto the roller.

[0028] A second hydraulic rod 10 is installed on the ground below the extraction mechanism. A valve is installed at the bottom of the pressing barrel 4. A through groove is opened at the bottom of the mesh basket 11 for the output end of the second hydraulic rod 10 to pass through. After the output end of the second hydraulic rod 10 is extended, it pushes the mesh plate 12 upward through the opened valve and through groove.

[0029] The extraction mechanism includes a first mounting frame 5, and the extrusion assembly includes a first hydraulic rod 7 mounted on the top of the first mounting frame 5. A piston head 6 is fixedly connected to the output end of the first hydraulic rod 7. After the piston head 6 moves downward, it forms the top of the processing space.

[0030] The telescopic rotating assembly includes two electric telescopic rods 8 mounted on the top of the first mounting frame 5. The output end of the electric telescopic rods 8 is fixedly connected to a fixed housing 16. A rotating motor is installed inside the fixed housing 16. The output end of the rotating motor is fixedly connected to a fixed plate 22. Multiple annular components are located between the two fixed plates 22. A clamping block 23 is installed on the side of the fixed plate 22 away from the fixed housing 16. The side of the clamping block 23 away from the fixed plate 22 clamps the outside of the multiple annular components.

[0031] The clamping block 23 uses existing technology to clamp and release the ring assembly, which facilitates the telescopic rotating assembly to drive multiple ring assemblies to rise, fall and rotate.

[0032] The fixing assembly includes two second mounting brackets 9 fixedly connected to the middle of the first mounting bracket 5. Two first mounting blocks 17 are fixedly connected to each adjacent side of the two second mounting brackets 9. The side of the two first mounting blocks 17 away from the second mounting brackets 9 abuts against the outside of the multiple ring components after they have moved downward. Multiple second electromagnets 25 are installed on the first mounting blocks 17. The multiple second electromagnets 25 are magnetically engaged with the multiple ring components one by one.

[0033] Reference Figure 7-11 Multiple ring components are stacked vertically, with adjacent ring components magnetically engaged and clamping the same separator ring 21. Each ring component includes a first arc-shaped block 19 and a second arc-shaped block 20. Both the first arc-shaped block 19 and the second arc-shaped block 20 are clamped and engaged with the separator ring 21. Two third electromagnets 29 are installed on adjacent sides of the first arc-shaped block 19 and the second arc-shaped block 20. The third electromagnets 29 are magnetically engaged with the separator ring 21. A mounting housing 26 is fixedly connected to the side of the first arc-shaped block 19 away from the separator ring 21. The mounting housing 26 and the side opposite to the second arc-shaped block 20 are clamped and engaged with the clamping block 23 and the first mounting block 17, and are magnetically engaged with the second electromagnet 25.

[0034] Adjacent ring components are magnetically coupled through small electromagnets or small permanent magnets to maintain the overall stability when multiple ring components are stacked. The magnetic attraction force of the small permanent magnets is less than the force of the clamping block 23 in clamping the separated ring components, thus avoiding hindering the clamping block 23 from driving the movement and rotation of some ring components.

[0035] A small fan is installed inside the partition ring 21, and a through-hole 30 is opened in the middle. The air extraction end of the small fan adsorbs the corresponding gauze 32 through the negative pressure at the top and bottom of the through-hole 30.

[0036] After the gauze 32 is stretched, the part of it that rests near the through-hole 30 forms a sealed structure, which is convenient for being adsorbed and fixed by negative pressure.

[0037] Both the first arc-shaped block 19 and the second arc-shaped block 20 are provided with cutting grooves for the blade 31 to slide. The two adjacent cutting grooves are located at the top and bottom of the separator ring 21, respectively. Both ends of the blade 31 are equipped with telescopic devices 28. The end of the telescopic device 28 away from the blade 31 is fixedly connected to a connecting block 27. The connecting block 27 is magnetically engaged with the output end of the drive component.

[0038] The telescopic device 28 adopts existing technology. The output ends of the two telescopic devices 28 extend and retract asynchronously, which can drive the blade 31 to move back and forth to form a sawing effect.

[0039] The bottom of the mounting housing 26 is connected to a collection trough 33. A clamping pad 34 is fixedly connected to the end of the cutting groove on the second arc-shaped block 20 away from the mounting housing 26. The clamping pad 34 clamps and cooperates with the blade edge of the blade 31. A sponge is fixedly connected inside the clamping pad 34. A slanted groove 35 is opened on the top of the blade 31, and the bottom end of the slanted groove 35 faces the blade edge of the blade 31.

[0040] The housing 26 houses a winding motor, whose output is coaxially and fixedly connected to the rollers, allowing for active control of the roller rotation to wind and unwind the gauze 32. This, in conjunction with the movement of the blades 31, enables the cutting and layering of orange peel.

[0041] The drive assembly includes two drive motors 13 mounted on the second mounting bracket 9. The output end of the drive motor 13 is coaxially fixedly connected to a lead screw 14. The lead screw 14 is rotatably connected between the two second mounting brackets 9. A second mounting block 18 is threadedly connected to the lead screw 14. A limit rod 15 is slidably connected to the second mounting block 18. The limit rod 15 is fixedly connected between the two second mounting brackets 9. A plurality of first electromagnets 24 are mounted on the second mounting block 18. The plurality of first electromagnets 24 are magnetically engaged with a plurality of connecting blocks 27 one by one.

[0042] In this invention, the main process involves pressing orange peels to extract essential oils.

[0043] First, before pressing, the fresh, mold-free orange peels need to be rinsed with clean water to remove impurities and dust from the surface. Then, the orange peels are spread out in a ventilated place to dry.

[0044] To prevent orange peels from slipping during pressing, increase oil yield, and reduce the viscosity of the pressing liquid, the orange peels are soaked in 7-8% lime water for more than 10 hours. During the soaking process, pectin reacts with lime water to produce calcium pectate, which is insoluble in water and helps with oil-water separation.

[0045] After soaking, the orange peels are thoroughly rinsed with running water to remove any residual lime water from the surface. At the same time, the pH value of the orange peels is adjusted to 7-8 to facilitate subsequent pressing and filtering operations.

[0046] Then, spread the prepared orange peels evenly inside the mesh basket 11.

[0047] Three pressing barrels 4 are slidably placed on the circular track 2 to ensure the continuity of pressing. After pressing at the pressing head 3, one pressing barrel 4 can slide along the circular track 2 to the position of the first mounting frame 5 for cutting, layering and flipping. At this time, the other pressing barrels 4 can continue to press, realizing the whole process without interruption and improving pressing efficiency.

[0048] In addition, the three pressing barrels 4 alternately bear the hydraulic pressure of the pressing head 3, which avoids the single pressing barrel 4 being under high pressure for a long time, thus preventing equipment fatigue and extending its service life.

[0049] After the orange peel inside the pressing barrel 4 is initially pressed at the pressing head 3, the pressing barrel 4 will move to the first mounting frame 5.

[0050] First, the cutting preparation is carried out. The output ends of the two electric telescopic rods 8 are extended and, through the fixed housing 16, the fixed plate 22 and the clamping block 23, drive multiple ring components to move downward to the top of the pressing barrel 4. At this time, multiple ring components are simultaneously clamped and fixed by four first mounting blocks 17. This fixing force is less than the clamping force of the clamping block 23 and is magnetically attracted and fixed by the second electromagnet 25 on the first mounting block 17.

[0051] At the same time, the valve at the bottom of the pressing barrel 4 is opened, the output end of the second hydraulic rod 10 extends, and through the opened valve and the through groove at the bottom of the basket 11, the screen plate 12 is pushed up, lifting the orange peel after preliminary pressing into the interior of multiple ring components.

[0052] Then the output end of the first hydraulic rod 7 extends, lowers the piston head 6, and abuts against the top of the orange peel. The upper surface of the mesh plate 12, the lower surface of the piston head 6, and the inner side of multiple annular components form a processing space. The processing space limits the orange peel, making it easier to cut it later.

[0053] The piston head 6 presses the orange peel down from top to bottom to prevent it from slipping during cutting and to ensure that the peel remains unfolded, thus ensuring better cutting of the oil sacs on the orange peel.

[0054] Next, the cutting process is carried out. The drive motor 13 is started, which drives the lead screw 14 to rotate. Under the limiting action of the limit rod 15, the lead screw 14 drives the second mounting block 18 to move. The two second mounting blocks 18 move synchronously, thereby driving multiple blades 31 to move. The blades 31 perform preliminary horizontal cutting on the orange peel inside the processing space, applying more uniform pressure to the orange peel and reducing the deformation problems that may be caused by vertical cutting.

[0055] Both sides of the blade 31 are equipped with telescopic devices 28. The two telescopic devices 28 extend and retract asynchronously, which allows the blade 31 to move back and forth longitudinally, improving the cutting effect of the blade 31 on orange peel.

[0056] The blade 31 moves inside the cutting groove until it is inserted into the clamping pad 34 at one end of the cutting groove and is clamped by the clamping pad 34. When the blade 31 moves, it drives the gauze 32 to move together, thereby separating the orange peel into layers.

[0057] After cutting and layering the stacked orange peels, they are flipped over.

[0058] First, the telescopic rotating assembly clamps the two upper ring components through the clamping block 23, disconnecting the magnetic connection between these two ring components and other electromagnets to prevent their upward movement from being obstructed. The telescopic rotating assembly drives these two ring components and a corresponding separator ring 21 to move upward, carrying the top orange peel upward. After its rotation is unobstructed, the rotating motor inside the fixed housing 16 is activated. The output ends of the two rotating motors rotate, driving the two ring components to rotate, thus flipping the top orange peel.

[0059] Then, after the uppermost separating ring 21 is lowered by the electric telescopic rod 8, the telescopic rotating component clamps the upper three ring components through the clamping block 23. The above operation is repeated to flip the upper two layers of orange peel until the layered flipping operation of the orange peel inside the processing space is completed.

[0060] After the orange peel is flipped and layered, it is reset and cut. The yarn 32 is wound up by the roller, and the blade 31 is moved and reset by the drive motor 13 to reset and cut the orange peel inside the processing space.

[0061] At the same time, the cutting, flipping, and resetting cutting processes can be repeated to process the orange peel multiple times, thus improving the cutting effect.

[0062] During the cutting and turning process, because the oil sacs on the orange peel have a sac-like structure and are scattered in the epidermal cells, these oil sacs are the main parts for storing essential oils. When the blade 31 is cut parallel to the orange peel, the blade can contact the surface of multiple oil sacs more directly. In the subsequent re-pressing process, the essential oil in these ruptured oil sacs is more easily squeezed out, thereby improving the extraction efficiency of essential oils.

[0063] Compared to the vertical cutting method, where the blade mainly cuts along the thickness of the orange peel, it can only cut into a small number of oil sacs along the path of the blade, thus failing to fully release the essential oils in the orange peel.

[0064] In addition, taut gauze 32 is used as the contact surface on both sides of the layered orange peel during the flipping process, while providing sufficient support to ensure that the orange peel remains intact during the flipping process.

[0065] The separator ring 21 is equipped with a small fan. When the gauze 32 separates the orange peel into layers, the small fan works and uses the upper and lower through-holes 30 to draw the upper and lower gauze 32 under negative pressure, thereby improving the stability of the gauze 32 support.

[0066] In addition, the gauze 32 is made of modified polyester fiber, which can quickly absorb the oil and water mixture on the surface of the orange peel. Since the oil sacs of the orange peel are irregularly distributed in the epidermal layer, the initial pressing may only damage some of the oil sacs, especially the side in contact with the pressing direction. By turning it over and then pressing it again, the area of ​​the oil sacs that have not been damaged can be turned over, reducing the essential oil residue caused by the deformation of the orange peel or insufficient rupture of the oil sacs.

[0067] By continuously increasing the number of layers and flipping them, it is ensured that each layer of orange peel will exchange contact surfaces with other layers of orange peel. Furthermore, the upper and lower surfaces of these layers are interchanged during flipping, allowing the oil sacs that were originally on different layers and partially obscured to be exposed more fully.

[0068] This allows the blade 31 to more thoroughly disrupt the oil sac structure during cutting, enabling more essential oils to be released.

[0069] In addition, the blade 31 is provided with a slanted groove 35, which allows the oil-water mixture flowing out during the cutting process to be collected in the slanted groove 35 and then flow to the cutting edge of the blade 31. It is then applied to the surface of the orange peel during subsequent cutting, which avoids excessive contact between the oil-water mixture and air, reducing evaporation loss. At the same time, since the oil-water mixture is applied back to the surface of the orange peel, the amount of essential oil lost during the cutting process is reduced, the extraction rate of essential oil is improved, and it also plays a certain role in lubrication and softening, reducing cutting resistance.

[0070] The clamping pad 34 contains a sponge that can absorb any remaining oil-water mixture on the blade 31. After use, the sponge can be removed, and the oil-water mixture can be collected and reused by squeezing the sponge.

[0071] After the gauze 32 is wound up by the rollers, the excess oil-water mixture will fall into the collection tank 33, where it will be collected and reused.

[0072] After the orange peel inside the pressing barrel 4 is cut and turned over, the output end of the second hydraulic rod 10 retracts, and the screen plate 12 moves downward, allowing the orange peel to enter the interior of the mesh basket 11. The thickness of the screen plate 12 is greater than the mesh size of the cross-section of the mesh basket 11 to prevent leakage of the oil-water mixture.

[0073] Then the pressing barrel 4 moves to the position of the fixed frame 1, and the pressing head 3 moves downward to press the cut and turned orange peel again.

[0074] The oil-water mixture after two pressings is then filtered through a cloth bag to remove solids and other residues.

[0075] The filtrate is then further centrifuged using a high-speed centrifuge to separate the essential oil from the upper layer, thus completing the extraction of orange peel essential oil.

[0076] A method for extracting natural plants, comprising the above-mentioned natural plant extraction apparatus, and further comprising the following steps: S1: Preparation: Rinse the fresh orange peels and let them dry.
