Description

Technical Field

[0001] This invention relates to the field of rose essential oil production technology, specifically a rose essential oil production process and apparatus. Background Technology

[0002] Rose: is the common name for many plants and cultivated flowers in the Rosaceae family and Rosa genus. Rose essence is the essence of rose. Rose essence is made through strict distillation and extraction. It can be stored for 1 to 2 years without spoilage without any additives. This is because it contains rich water-soluble aromatic molecules and has strong antiseptic and antibacterial properties. Special distillation equipment is often required for the production and preparation of rose essence.

[0003] In existing methods for producing rose essential oil, rose petals are placed in a container with a certain amount of water, and then heated and distilled to extract the essential oil from the petals. After the rose petals inside the distillation tank have been extracted, workers need to manually remove the residue and replace it with fresh raw material. This process requires shutting down the equipment, which wastes a lot of time and reduces the extraction efficiency of rose essential oil. To address these issues, we provide a rose essential oil production process and apparatus to solve the above problems. Summary of the Invention

[0012] As a further embodiment of the present invention: the feeding assembly further includes a connecting push plate fixedly connected to the outside of the cylindrical inclined rod, and a second spring is installed between the connecting push plate and the fixed frame.

[0013] This invention also discloses a process for producing rose essential oil, using the aforementioned rose essential oil production apparatus, comprising the following steps:

[0014] S1. When the rose petals in the second filter tube inside the distillation tank have been distilled and need to be refilled, the drive motor can be started. The output of the drive motor drives the first spur gear to rotate, thereby driving one rack to move one of the first sealing plates upward and another rack to move the other first sealing plate downward. This causes the first filter tube containing the distilled rose petals to move upward and the first filter tube containing the rose petals to be distilled to move downward. This allows the rose petals to be distilled to be automatically fed into the distillation tank and the distilled rose petals to be automatically discharged. This reduces the connection time between manual feeding and unloading, allowing the device to perform continuous distillation operations and thus improving the efficiency of rose essential oil production.

[0015] As one of the racks moves upward, it drives the first sealing plate to move upward, causing the first sealing plate to separate from the inner side of the partition. When the rack moves upward to its maximum position, the second sealing plate fits against the inner side of the partition, forming a seal for the inside of the distillation tank.

[0016] S2. After the rose petals to be distilled enter the distillation barrel, the first servo motor can be started to drive the second filter cylinder to rotate 90 degrees. The first servo motor then stops running. At this time, the ball rod has not yet contacted the inclined block. At the same time, the rack continues to move downward until the ball rod contacts the lowest point of the inclined block. At this time, the rack stops moving, and the second filter cylinder stops at the designated position. Then, the second servo motor is started. The output end of the second servo motor drives the second spur gear to rotate, causing the second filter cylinder to rotate inside the first filter cylinder. This allows the rose petals inside to be heated evenly. The rotation of the second filter cylinder helps to heat the rose petals evenly. During the distillation process, the steam needs to heat the petals to release the essential oil. If the petals are not heated evenly, the essential oil in some petals may not be fully released. The rotation of the second filter cylinder can ensure that each petal is heated evenly, thereby fully releasing the essential oil.

[0017] S3. When the second filter cylinder moves downward to the designated position, it rotates in a circular motion, causing the spherical rod to rotate on the inclined block. This pushes the spherical rod to move the auxiliary rod into the second filter cylinder, which in turn moves one of the extrusion plates into the second filter cylinder. As the extrusion plate moves, it also moves the fixed sleeve and the cylindrical push rod into the second filter cylinder. This causes the cylindrical push rod to drive the drive rack to move laterally, driving the two auxiliary spur gears to rotate. The two auxiliary spur gears then drive the cylindrical rack to move into the second filter cylinder, pushing the other extrusion plate into the second filter cylinder. This causes the two extrusion plates to move relative to each other, squeezing the rose petals inside the second filter cylinder and promoting the release of essential oils, thereby improving the efficiency of rose petal distillation.

[0018] When one end of the spherical rod moves from the highest point to the lowest point of the inclined block, the squeezing force on the first spring gradually decreases, causing the two squeezing plates to move in opposite directions to reset. When the second filter cylinder continues to rotate, the two squeezing plates reciprocate, repeatedly squeezing the rose petals inside the second filter cylinder. The reciprocating squeezing mechanism can apply pressure to the rose petals, which helps to squeeze out the essential oil from the petals and further improve the extraction efficiency.

[0019] S4. Four rectangular blocks are fixedly connected to the outer wall of the first filter cylinder, and each rectangular block is aligned with a guide groove. The second servo motor is started and stopped under the control of the PLC controller. When the first filter cylinder moves into the feed barrel, the second pipe and the first pipe are respectively attached to a rectangular block and aligned with a guide groove. The second servo motor drives the second filter cylinder to rotate to a designated position under the control of the PLC controller, so that the guide groove opened inside it is aligned with the guide groove opened inside the first filter cylinder. When it is necessary to feed the inside of the second filter cylinder, firstly, the rose petals are fed into the second pipe from the petal conveying port and the fan is started at the same time. The fan blows the rose petals inside the second pipe into the second filter cylinder through the guide groove, thereby realizing the automatic feeding of rose petals.

[0020] S5. When the two guide troughs are aligned with the first pipe and the second pipe respectively, the suction pump is started, and the electric telescopic rod is started to drive the suction port to move the suction hose into the interior of the first filter cylinder. The residue inside the first filter cylinder is sucked away through the input port at the bottom of the suction port, thereby realizing the automatic discharge function without the need for manual operation by the staff, thus improving the overall convenience of the device.

[0021] S6. When the fixed sleeve and the sliding sleeve move relative to each other, the abutting inclined surface on the sliding sleeve abuts against the inclined surface at the end of the cylindrical inclined rod, pushing the cylindrical inclined rod to move inside the fixed frame and compressing the second spring, thereby driving the rectangular plate to move, causing the arc plate to push the petals inside the second filter cylinder outward. When the sliding sleeve moves away from the fixed sleeve, the sliding sleeve no longer abuts against the cylindrical inclined rod, the second spring releases and pushes the cylindrical inclined rod back to its original position, and the arc plate drags the rose petals outside the second filter cylinder inward. Through the reciprocating motion of the fixed sleeve and the sliding sleeve, the position and state of the petals can be dynamically changed. The rotation and reciprocating compression of the second filter cylinder cause the rose petals to move and change position continuously inside the filter cylinder, thus making the contact with the steam more sufficient and dynamic. This dynamic contact can greatly improve the extraction efficiency of essential oils.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. By setting up an alternating feeder, the output of the drive motor drives the first spur gear to rotate, thereby driving a rack to move one first sealing plate upward and another rack to move another first sealing plate downward. This causes the first filter cylinder containing distilled rose petals to move upward and the first filter cylinder containing rose petals to be distilled to move downward. This allows the rose petals to be distilled to be automatically fed into the distillation tank and the distilled rose petals to be automatically discharged. This reduces the connection time between manual feeding and unloading, enabling the device to perform continuous distillation operations and thus improving the efficiency of rose essential oil production.

[0024] 2. By setting up a squeezing mechanism, when one end of the ball rod moves from the highest point to the lowest point of the inclined block, the squeezing force on the first spring gradually decreases, causing the two squeezing plates to move in opposite directions to reset. When the second filter cylinder continues to rotate, the two squeezing plates reciprocate, repeatedly squeezing the rose petals inside the second filter cylinder. The reciprocating squeezing mechanism can apply pressure to the rose petals, which helps to squeeze out the essential oil from the petals and further improve the extraction efficiency.

[0025] 3. By setting up a feeding component, when the fixed sleeve and the sliding sleeve move relative to each other, the abutting inclined surface on the sliding sleeve abuts against the inclined surface at the end of the cylindrical inclined rod, pushing the cylindrical inclined rod to move inside the fixed frame and compressing the second spring, thereby driving the rectangular plate to move. This causes the arc plate to push the petals inside the second filter cylinder outward. When the sliding sleeve moves in opposite directions from the fixed sleeve, the sliding sleeve no longer abuts against the cylindrical inclined rod, the second spring releases and pushes the cylindrical inclined rod back to its original position, and the arc plate drags the rose petals outside the second filter cylinder inward. Through the reciprocating motion of the fixed sleeve and the sliding sleeve, the position and state of the petals can be dynamically changed. The feeding action of the rotation and reciprocating compression of the second filter cylinder causes the rose petals to move and change position continuously inside the filter cylinder, thus making the contact with the steam more sufficient and dynamic. This dynamic contact can greatly improve the extraction efficiency of essential oils.

[0026] 4. By setting up a material exchange unit, after the first filter cylinder moves into the feed cylinder, the residue inside the first filter cylinder can be sucked away by the material exchange unit. After the first filter cylinder is cleaned, the rose petals to be processed can be automatically transported into the first filter cylinder, thereby realizing the function of automatic feeding and slag discharge of rose petals, thus improving the overall practicality of the device.

[0043] Example 1

[0044] Please see Figures 1 to 13This embodiment provides a rose essence production apparatus, including: auxiliary components including a fixed sleeve 38 fixedly connected to the inner side of one of the extrusion plates 34, a sliding sleeve 36 installed inside the fixed sleeve 38, limit blocks fixedly connected to both sides of the sliding sleeve 36, and a sliding groove matching the limit blocks opened inside the fixed sleeve 38.

A cylindrical push rod 35 is fixedly connected to the inner side of one of the extrusion plates 34. A drive rack 33 is fixedly connected to one end of the cylindrical push rod 35. One end of the drive rack 33 passes through the other extrusion plate 34 and extends to the outside of a second filter cylinder 16. The end is fixedly connected to a limiting seat 49, and an auxiliary spur gear 31 is rotatably connected to the inner side of the limiting seat 49. The auxiliary spur gear 31 meshes with a drive rack 33. One end of another extrusion plate 34 is fixedly connected to two cylindrical racks 29 that mesh with the auxiliary spur gear 31. The material changing unit includes two second pipes 4 and two first pipes 3 fixedly connected to the outside of the feeding barrel 2, and one end of each of the two second pipes 4 and the two first pipes 3 extends into the inside of the feeding barrel 2. The two first pipes 3 and the two second pipes 4 are symmetrically arranged about the center of the feeding barrel 2. A petal conveying port 6 is installed at the top inlet of each of the two second pipes 4. A fan 24 is installed at one end of the second pipe 4, and an air inlet communicating with the fan 24 is opened at one end of the second pipe 4. Furthermore, a filter screen is installed inside the air inlet, and an electric telescopic rod 46 is fixedly connected inside the two first pipes 3. A suction port 47 is fixedly connected to the actuating end of the electric telescopic rod 46. A suction hose 5 is installed at the air inlet end of the suction port 47, and a suction pump 48 is installed at one end of the suction hose 5. The suction pump 48 is mounted on the base 7. The alternating feeder includes a drive motor 21 fixedly connected to the top of the feed hopper 2. A first spur gear 22 is fixedly connected to the actuating end of the drive motor 21. Two first sealing plates 11 are provided on the top of the partition 10. A rack 8 and a guide rod 9 are fixedly connected to the top of the two first sealing plates 11, respectively. One end of the guide rod 9 extends through to the outside of the feed hopper 2 and is slidably connected to the feed hopper 2. One side of each rack 8 is connected to the first spur gear 22. Gears 22 mesh. Two second fixing rods 15 are fixedly connected to the bottom of the first sealing plate 11. A first fixing rod 14 is fixedly connected to one side of the second fixing rod 15. A second sealing plate 20 is fixedly connected to the bottom of the first fixing rod 14. An auxiliary sealing block 12 is fixedly connected to one side of each first sealing plate 11 and second sealing plate 20. A first filter cylinder 13 is rotatably connected to the inner side of the second fixing rod 15 via a rotating shaft. A first servo motor 26 is fixedly connected to one side of the second fixing rod 15. The actuating end of the first servo motor 26 extends through to the outside of the second fixing rod 15 and is fixedly connected to the first filter cylinder 13. The alternating feeder also includes a housing 27 fixedly connected to the outside of the first filter cylinder 13. A second servo motor 30 is fixedly connected inside the housing 27.The actuator of the second servo motor 30 extends through the outer casing 27 and is fixedly connected to a second spur gear 28. An auxiliary groove 23 extending into the feed tank 2 is provided inside the distillation tank 1. The diameter of the auxiliary groove 23 is larger than the diameter of the second spur gear 28, and the size of the auxiliary groove 23 matches the size of the auxiliary sealing block 12. A second filter cylinder 16 is rotatably connected inside the first filter cylinder 13. Both the first filter cylinder 13 and the second filter cylinder 16 have two guide grooves 17 extending through to their interiors on their outer sides. A circular gear 32 that meshes with the second spur gear 28 is fixedly connected inside the second filter cylinder 16.

[0045] When the rose petals in the second filter cylinder 16, which are still inside the distillation tank 1, have finished distilling and need to be refilled, the drive motor 21 can be started. The output of the drive motor 21 drives the first spur gear 22 to rotate, thereby driving a rack 8 to move a first sealing plate 11 upward and another rack 8 to move another first sealing plate 11 downward. This causes the first filter cylinder 13 containing the distilled rose petals to move upward and the first filter cylinder 13 containing the rose petals to be distilled to move downward. This allows the rose petals to be distilled to be automatically fed into the distillation tank 1 and the distilled rose petals to be automatically discharged. This reduces the connection time between manual feeding and unloading, allowing the device to perform continuous distillation operations and thus improving the efficiency of rose essential oil production.

[0046] When a rack 8 moves upward, it drives the first sealing plate 11 to move upward, causing the first sealing plate 11 to separate from the partition 10 on the inside. When the rack 8 moves upward to the maximum position, the second sealing plate 20 fits into the inside of the partition 10, forming a seal for the inside of the distillation tank 1.

[0047] Once the rose petals to be distilled enter the distillation tank 1, the first servo motor 26 can be started to drive the second filter cylinder 16 to rotate 90 degrees. After the first servo motor 26 stops running, the ball rod 25 has not yet contacted the inclined block 19. At the same time, the rack 8 continues to move downward until the ball rod 25 contacts the lowest point of the inclined block 19. At this point, the rack 8 stops moving, and the second filter cylinder 16 stops at the designated position. Then, the second servo motor 30 is started. The output end of the second servo motor 30 drives the second spur gear 28 to rotate, causing the second filter cylinder 16 to rotate inside the first filter cylinder 13. This ensures that the rose petals inside are heated evenly. The rotation of the second filter cylinder 16 helps to ensure that the rose petals inside are heated evenly. During the distillation process, the steam needs to heat the petals to release the essential oil. If the petals are not heated evenly, the essential oil in some petals may not be fully released. The rotation of the second filter cylinder 16 ensures that each petal is heated evenly, thereby fully releasing the essential oil.

[0048] Four rectangular blocks are fixedly connected to the outer wall of the first filter cylinder 13, and each rectangular block is aligned with a guide chute 17. The second servo motor 30 is started and stopped under the control of the PLC controller. When the first filter cylinder 13 moves into the feed hopper 2, the second pipe 4 and the first pipe 3 are respectively attached to a rectangular block and aligned with a guide chute 17. The second servo motor 30 drives the second filter cylinder 16 to rotate to the designated position under the control of the PLC controller, so that the guide chute 17 opened inside it is aligned with the guide chute 17 opened inside the first filter cylinder 13. When it is necessary to feed the inside of the second filter cylinder 16, firstly, the rose petals are fed into the inside of the second pipe 4 from the petal conveying port 6 and the fan 24 is started at the same time. The fan 24 blows the rose petals inside the second pipe 4 into the inside of the second filter cylinder 16 through the guide chute 17, thereby realizing the automatic feeding of rose petals.

[0049] When the two guide troughs 17 are aligned with the first pipe 3 and the second pipe 4 respectively, the suction pump 48 is started, and the electric telescopic rod 46 is started to drive the suction port 47 to move the suction hose 5 into the interior of the first filter cylinder 13. The residue inside the first filter cylinder 13 is sucked away through the input port at the bottom of the suction port 47, thereby realizing the function of automatic discharge without the need for manual operation by the staff, thus improving the overall convenience of the device.

[0050] Example 2

[0051] The squeezing mechanism, located inside the distillation tank 1, is used to reciprocate the squeezing of rose petals during distillation. The squeezing mechanism includes two squeezing plates 34 slidably connected inside the second filter cylinder 16. One end of one squeezing plate 34 is fixedly connected to an auxiliary rod 18, and one end of the auxiliary rod 18 extends through to the outer wall of the second filter cylinder 16 and is fixedly connected to a ball-shaped rod 25. An inclined block 19, abutting against the ball-shaped rod 25, is fixedly connected inside the distillation tank 1. An auxiliary component for pushing the other squeezing plate 34 is provided inside one of the squeezing plates 34. The auxiliary component includes a fixed sleeve 38 fixedly connected to the inner side of one of the squeezing plates 34. A sliding sleeve 36 is installed inside the fixed sleeve 38, and limit blocks are fixedly connected to both sides of the sliding sleeve 36. The sleeve 38 has a groove inside that matches the limiting block. The fixed sleeve 38 is slidably connected to the sliding sleeve 36 through the limiting blocks fixedly connected on both sides. A first spring 37 is installed between the two extrusion plates 34. A cylindrical push rod 35 is fixedly connected to the inner side of one of the extrusion plates 34. A drive rack 33 is fixedly connected to one end of the cylindrical push rod 35. One end of the drive rack 33 passes through the other extrusion plate 34 and extends to the outside of the second filter cylinder 16. A limiting seat 49 is fixedly connected to one end of the second filter cylinder 16. An auxiliary spur gear 31 is rotatably connected to the inner side of the limiting seat 49. The auxiliary spur gear 31 meshes with the drive rack 33. Two cylindrical racks 29 that mesh with the auxiliary spur gear 31 are fixedly connected to one end of the other extrusion plate 34.

[0052] When the second filter cylinder 16 moves downward to the designated position, it rotates in a circular motion, causing the spherical rod 25 to rotate on the inclined block 19. This pushes the spherical rod 25 to move the auxiliary rod 18 into the second filter cylinder 16, which in turn moves a pressing plate 34 into the second filter cylinder 16. As the pressing plate 34 moves, it also moves the fixed sleeve 38 and the cylindrical push rod 35 into the second filter cylinder 16. This causes the cylindrical push rod 35 to drive the drive rack 33 to move laterally, which in turn drives two auxiliary spur gears 31 to rotate. The two auxiliary spur gears 31 drive the cylindrical rack 29 into the second filter cylinder 16, pushing the other pressing plate 34 into the second filter cylinder 16. This causes the two pressing plates 34 to move relative to each other, squeezing the rose petals inside the second filter cylinder 16 and promoting the release of essential oils, thereby improving the efficiency of rose petal distillation.

[0053] When one end of the ball rod 25 moves from the highest point to the lowest point of the inclined block 19, the squeezing force on the first spring 37 gradually decreases, causing the two squeezing plates 34 to move in opposite directions to reset. When the second filter cylinder 16 continues to rotate, the two squeezing plates 34 reciprocate, repeatedly squeezing the rose petals inside the second filter cylinder 16. The reciprocating squeezing mechanism can apply pressure to the rose petals, which helps to squeeze out the essential oil from the petals and further improve the extraction efficiency.

[0054] Example 3

[0055] The feeding assembly, located inside the distillation tank 1, is used to feed rose petals. The feeding assembly includes multiple fixed frames 40 fixedly connected to the outside of the fixed sleeve 38. A cylindrical inclined rod 45 is slidably connected inside each fixed frame 40. One end of the cylindrical inclined rod 45 passes through the fixed sleeve 38 and extends into the inside of the fixed sleeve 38. A rectangular plate 41 is fixedly connected to one end of the cylindrical inclined rod 45. Two arc-shaped plates 42 are fixedly connected to the outside of the rectangular plate 41, and the two arc-shaped plates 42 are arranged opposite to each other. An abutment inclined surface 43 is provided on the top of the sliding sleeve 36. The feeding assembly also includes a connecting push plate 44 fixedly connected to the outside of the cylindrical inclined rod 45. A second spring 39 is installed between the connecting push plate 44 and the fixed frame 40.

[0056] When the fixed sleeve 38 and the sliding sleeve 36 move relative to each other, the abutting inclined surface 43 on the sliding sleeve 36 abuts against the inclined surface at the end of the cylindrical inclined rod 45, pushing the cylindrical inclined rod 45 to move inside the fixed frame 40 and compressing the second spring 39, thereby driving the rectangular plate 41 to move, so that the arc plate 42 pushes the petals inside the second filter cylinder 16 outward. When the sliding sleeve 36 moves away from the fixed sleeve 38, the sliding sleeve 36 no longer abuts against the cylindrical inclined rod 45, the second spring 39 is released and pushes the cylindrical inclined rod 45 back to its original position, and the arc plate 42 drags the rose petals outside the second filter cylinder 16 inward. Through the reciprocating motion of the fixed sleeve 38 and the sliding sleeve 36, the position and state of the petals can be dynamically changed. The rotation and reciprocating compression of the second filter cylinder 16 cause the rose petals to move and change position continuously inside the filter cylinder, so that the contact with the steam is more sufficient and dynamic. This dynamic contact can greatly improve the extraction efficiency of essential oil.

[0057] The following describes a rose essential oil production process based on the aforementioned rose essential oil production apparatus, specifically including the following steps:

[0058] S1. When the rose petals in the second filter cylinder 16, which are retained inside the distillation tank 1, have been distilled and need to be refilled, the drive motor 21 can be started. The output of the drive motor 21 drives the first spur gear 22 to rotate, thereby driving a rack 8 to move a first sealing plate 11 upward and another rack 8 to move another first sealing plate 11 downward. This causes the first filter cylinder 13 containing the distilled rose petals to move upward and the first filter cylinder 13 containing the rose petals to be distilled to move downward. This allows the rose petals to be distilled to be automatically fed into the distillation tank 1 and the distilled rose petals to be automatically discharged. This reduces the connection time between manual feeding and unloading by the staff, allowing the device to perform continuous distillation operations and thus improving the efficiency of rose essential oil production.

[0059] When a rack 8 moves upward, it drives the first sealing plate 11 to move upward, causing the first sealing plate 11 to separate from the partition 10 on the inside. When the rack 8 moves upward to the maximum position, the second sealing plate 20 fits into the inside of the partition 10, forming a seal for the inside of the distillation tank 1.

[0060] S2. After the rose petals to be distilled enter the distillation tank 1, the first servo motor 26 can be started to drive the second filter cylinder 16 to rotate 90 degrees and then the first servo motor 26 stops running. At this time, the ball rod 25 has not yet contacted the inclined block 19, and the rack 8 continues to move downward until the ball rod 25 contacts the lowest point of the inclined block 19. At this time, the rack 8 stops moving, and the second filter cylinder 16 stops at the designated position. Then the second servo motor 30 is started. The output end of the second servo motor 30 drives the second spur gear 28 to rotate, which drives the second filter cylinder 16 to rotate inside the first filter cylinder 13, so that the rose petals inside can be heated evenly. The rotation of the second filter cylinder 16 helps to heat the rose petals inside evenly. During the distillation process, the steam needs to heat the petals to release the essential oil. If the petals are not heated evenly, the essential oil of some petals may not be fully released. The rotation of the second filter cylinder 16 can ensure that each petal is heated evenly, thereby fully releasing the essential oil.

[0061] S3. When the second filter cylinder 16 moves downward to the designated position, the second filter cylinder 16 rotates in a circular motion, causing the spherical rod 25 to rotate on the inclined block 19. This pushes the spherical rod 25 to move the auxiliary rod 18 into the second filter cylinder 16, which in turn moves a squeezing plate 34 into the second filter cylinder 16. As the squeezing plate 34 moves, it also moves the fixed sleeve 38 and the cylindrical push rod 35 into the second filter cylinder 16. This causes the cylindrical push rod 35 to drive the drive rack 33 to move laterally, driving two auxiliary spur gears 31 to rotate. The two auxiliary spur gears 31 drive the cylindrical rack 29 into the second filter cylinder 16, pushing the other squeezing plate 34 into the second filter cylinder 16. This causes the two squeezing plates 34 to move relative to each other, squeezing the rose petals inside the second filter cylinder 16, promoting the release of essential oils, and thus improving the efficiency of rose petal distillation.

[0062] When one end of the ball rod 25 moves from the highest point to the lowest point of the inclined block 19, the squeezing force on the first spring 37 gradually decreases, causing the two squeezing plates 34 to move in opposite directions to reset. When the second filter cylinder 16 continues to rotate, the two squeezing plates 34 reciprocate, repeatedly squeezing the rose petals inside the second filter cylinder 16. The reciprocating squeezing mechanism can apply pressure to the rose petals, which helps to squeeze out the essential oil from the petals and further improve the extraction efficiency.

[0063] S4. Four rectangular blocks are fixedly connected to the outer wall of the first filter cylinder 13, and each rectangular block is aligned with a guide chute 17. The second servo motor 30 is started and stopped under the control of the PLC controller. When the first filter cylinder 13 moves into the feed hopper 2, the second pipe 4 and the first pipe 3 are respectively attached to a rectangular block and aligned with a guide chute 17. The second servo motor drives the second filter cylinder 16 to rotate to the designated position under the control of the PLC controller, so that the guide chute 17 opened inside it is aligned with the guide chute 17 opened inside the first filter cylinder 13. When it is necessary to feed the inside of the second filter cylinder 16, firstly, the rose petals are fed into the second pipe 4 from the petal conveying port 6 and the fan 24 is started at the same time. The fan 24 blows the rose petals inside the second pipe 4 into the second filter cylinder 16 through the guide chute 17, thereby realizing the automatic feeding of rose petals.

[0064] S5. When the two guide troughs 17 are aligned with the first pipe 3 and the second pipe 4 respectively, the suction pump 48 is started, and the electric telescopic rod 46 is started to drive the suction port 47 to move the suction hose 5 into the interior of the first filter cylinder 13. The residue inside the first filter cylinder 13 is sucked away through the input port at the bottom of the suction port 47, thereby realizing the automatic discharge function without the need for manual operation by the staff, thus improving the overall convenience of the device.

[0065] S6. When the fixed sleeve 38 and the sliding sleeve 36 move relative to each other, the abutting inclined surface 43 on the sliding sleeve 36 abuts against the inclined surface at the end of the cylindrical inclined rod 45, pushing the cylindrical inclined rod 45 to move inside the fixed frame 40 and compressing the second spring 39, thereby driving the rectangular plate 41 to move, so that the arc plate 42 pushes the petals inside the second filter cylinder 16 outward. When the sliding sleeve 36 moves away from the fixed sleeve 38, the sliding sleeve 36 no longer abuts against the cylindrical inclined rod 45, the second spring 39 is released and pushes the cylindrical inclined rod 45 back to its original position, and the arc plate 42 drags the rose petals outside the second filter cylinder 16 inward. Through the reciprocating motion of the fixed sleeve 38 and the sliding sleeve 36, the position and state of the petals can be dynamically changed. The rotation and reciprocating compression of the second filter cylinder 16 cause the rose petals to move and change position continuously inside the filter cylinder, so that the contact with the steam is more sufficient and dynamic. This dynamic contact can greatly improve the extraction efficiency of essential oil.
