Description

Technical Field

[0001] This application relates to the technical field of fragrance extraction equipment, and in particular to a jasmine fragrance extraction device. Background Technology

[0002] Aromatic substances in plants are volatile aromatic compounds (hereinafter referred to as aromatic oils), which can be used to make tea, giving it a unique flavor. The extraction of aromatic oils often employs chemical solvent extraction, a method used for extracting substances that are difficult to distill, such as those found in flowers. The principle involves soaking the plant in a volatile organic solvent, which dissolves the aromatic oil. The solvent is then removed using vacuum evaporation or washing with water to obtain the essential oil or absolute oil.

[0003] Existing aroma extraction devices consist of two parts: a mixing chamber and a clarification chamber. Plants are placed in the mixing chamber and solvent is injected through a nozzle, allowing the plants to soak in an appropriate amount of solvent. This dissolves the aromatic oils in the plant into the solvent. The mixture is then stirred by a paddle located in the mixing chamber to form an emulsion. The emulsion is then lifted to the clarification chamber, where it separates into two liquid phases under gravity and is discharged from different outlets.

[0004] Regarding the aforementioned technologies, the solvent solubility is a constant. Once the soaked plants have released a relative amount of aromatic oil, no more aromatic oil will be released from the plants. To control production efficiency, the plants in the mixing chamber will be discharged during the set process, thus resulting in incomplete extraction of aromatic oil from the plants. Summary of the Invention

[0005] To improve upon the shortcomings of existing technologies in the incomplete extraction of aromatic oils from plants, this application provides a jasmine fragrance extraction device.

[0006] The following technical solution is adopted:

[0007] A jasmine fragrance extraction device includes a mixing chamber, a clarification chamber, a reagent tank, a fragrance collection tube, and a rotor. The fragrance collection tube has a processing groove. The rotor is rotatably connected to the processing groove. The processing groove includes a feeding section, an extrusion section, and a slag discharge section arranged circumferentially. The feeding section extends through the fragrance collection tube away from the ground to form a placement opening. The rotor has a Reichelk triangle shape in its longitudinal section. Each triangle of the rotor is slidably connected to a barrier that abuts against the inner wall of the processing groove. After the rotor rotates, it cooperates with the inner wall of the extrusion section to extrude petals. The reagent tank supplies solvent to the feeding section through a liquid supply nozzle. The extrusion section has a liquid outlet groove near the ground. The clarification chamber is connected to the liquid outlet groove through a liquid outlet pipe. The slag discharge section has a slag discharge groove on the side near the ground for the extruded petals to enter. The mixing chamber is connected to the slag discharge groove through a slag discharge pipe. The mixing chamber and the clarification chamber are connected by a connecting pipe.

[0008] By adopting the above technical solution, the Leroy triangle is the smallest area that can be formed by a curve of constant width, and its area can be calculated using Lebesgue integrals. Petals are continuously placed into the feeding section of the processing tank through the placement port. The rotor rotates, and the blocking components move the petals. As the petals gradually transition from the feeding section to the extrusion section with the rotor, the distance between the rotor sidewall and the inner wall of the processing tank gradually decreases, allowing the rotor to press the petals against the collecting cylinder wall. Since there is a solvent supply nozzle in the feeding section, some of the tissue fluid seeps out and dissolves in the solvent after the petals are squeezed. The mixture flows into the outlet tank and then through the outlet pipe to the clarification chamber. The pressed petals continue to be pushed by the rotor and the blocking components into the slag discharge section. Under gravity, they fall from the slag discharge tank into the mixing chamber for soaking treatment, and the upper layer of liquid is sent to the clarification chamber. Simultaneously, petals adhering to the rotor wall are washed away by the solution when the rotor rotates back to the solvent supply nozzle, making them easier to fall off. This provides a more complete method for extracting aromatic oils from petals.

[0009] Optionally, a first through hole communicating with the feeding part is provided on the outer wall of the fragrance collecting cylinder, the liquid dispensing nozzle is inserted in the first through hole, and a first sleeve for fixing the liquid dispensing nozzle is provided on the outer wall of the fragrance collecting cylinder at the first through hole.

[0010] By adopting the above technical solution, the liquid supply nozzle is installed through the first through hole, which facilitates the setting of the nozzle, and the first sleeve is used to fix the liquid supply nozzle.

[0011] Optionally, a second through hole communicating with the slag discharge section is provided on the outer wall of the fragrance collection tube. A flushing nozzle connected to the reagent box is provided in the second through hole. The flushing nozzle is provided in the second through hole and the opening of the flushing nozzle faces the outer wall of the rotor. A second sleeve for fixing the flushing nozzle is provided on the outer wall of the fragrance collection tube at the second through hole.

[0012] By adopting the above technical solution, when the rotor passes through the slag discharge section, most of the pressed petals fall into the pressing tank, while some petals adhere to the outer wall of the rotor. The outer wall of the rotor is washed by the flushing nozzle, causing the petals to fall off, thereby keeping the rotor surface clean.

[0013] Optionally, the processing tank further includes a rinsing section located between the slag discharge section and the feeding section. A third through hole communicating with the rinsing section is provided on the outer wall of the aroma collection cylinder. A spray nozzle communicating with the reagent box is inserted through the third through hole. The opening of the spray nozzle faces the outer wall of the rotor. A third sleeve for fixing the spray nozzle is provided on the outer wall of the aroma collection cylinder at the third through hole.

[0014] By adopting the above technical solution, the rotor enters the rinsing section after passing through the slag discharge section. The spray in the rinsing section sprays solvent on the rotor surface. If the solvent is insoluble in water, water can also be used for rinsing, thereby rinsing the rotor a second time, so that the petals are separated from the rotor surface and mixed again with the newly fed petals in the feeding section before entering the next step.

[0015] Optionally, a filter screen for filtering petal residue is provided at the position where the liquid outlet trough communicates with the squeezing part. The liquid outlet trough is funnel-shaped, and the liquid outlet pipe is connected to the end of the liquid outlet trough near the ground.

[0016] By adopting the above technical solution, the liquid outlet is set in a funnel shape to facilitate the discharge of tissue fluid that has been pressed and mixed with solvent. The filter screen is used to filter petal residue and prevent petal residue from falling into the liquid outlet, thereby efficiently guiding the mixed liquid.

[0017] Optionally, each of the rotor triangles has a connecting groove along its radius, and the barrier is slidably connected in the connecting groove. The connecting groove is provided with an elastic element that always allows the barrier to move towards the inner wall of the incense collecting cylinder.

[0018] By adopting the above technical solution, the barrier is always extended away from the rotor by the action of the elastic element. During the rotation of the rotor, the barrier and the rotor form a space that can drive the petals to move, so that the petals can move with the rotor. At the same time, the sliding of the barrier can prevent the structure from getting stuck during the movement.

[0019] Optionally, the end of the barrier away from the rotor is provided with a chamfer.

[0020] By adopting the above technical solution, the barrier can slide more smoothly when it comes into contact with the inner wall of the incense collecting tube, reducing wear on the end of the barrier.

[0021] Optionally, the outer wall of the barrier is provided with a limiting block, and the rotor is provided with a limiting groove along the length direction of the barrier for the limiting block to move.

[0022] By adopting the above technical solution, the limiting block and the limiting groove restrict the transition displacement of the barrier component, prevent the limiting block from detaching from the rotor, and also increase the stability of the barrier component during movement.

[0023] Optionally, the mixing chamber is provided with a stirring mechanism for stirring the internal mixture.

[0024] Optionally, the side of the incense collecting cylinder away from the ground is provided with a feeding hopper that communicates with the placement opening.

[0025] In summary, this application includes at least one of the following beneficial effects:

[0026] 1. By rotating the rotor and using a barrier to move the petals, some tissue fluid is extracted from the petals, and the petals are then pushed into the mixing chamber, thus providing a more complete method for extracting aromatic oils from petals;

[0027] 2. The flushing nozzle works in conjunction with the spray nozzle to wash away the petals adhering to the rotor surface, keeping the rotor surface clean. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1 To be continued Figure 2 This application will be described in further detail.

[0032] Reference Figure 1 and Figure 2 This application discloses a jasmine fragrance extraction device, including a mixing chamber 6, a clarification chamber 7, a reagent box 4, a fragrance collection tube 1, and a rotor 3. The fragrance collection tube 1 is supported off the ground by a frame 5. The mixing chamber 6 and the clarification chamber 7 are both located below the fragrance collection tube 1. The reagent box 4 is located on one side of the fragrance collection tube 1 and is used to supply solvent into the fragrance collection tube 1. The rotor 3 is rotatably connected to the fragrance collection tube 1 and is driven by a stepper motor.

[0033] Reference Figure 2Specifically, the longitudinal section of rotor 3 is a Reichelcke triangle, which is the smallest area that can be formed by a curve of constant width. Its area can be calculated using Lebesgue integrals. Each triangle of rotor 3 is slidably connected to a barrier 32 that can abut against the inner wall of the processing groove. The incense collecting cylinder 1 has a processing groove, and rotor 3 is rotatably connected to the processing groove. The processing groove includes a feeding section 21, an extrusion section 22, and a slag discharge section 23 arranged circumferentially. The feeding section 21 is an arc-shaped channel for petals to slide into the extrusion section 22. The inner wall of the extrusion section 22 is vertically arranged. The inner wall is a vertical surface offset outward by a certain distance from the constant width line of rotor 3. When rotor 3 rotates to the position where the side wall corresponds to the inner wall of extrusion section 22, a gap remains between rotor 3 and the inner wall of extrusion section 22 to extrude some petals. After rotor 3 rotates, it cooperates with the inner wall of extrusion section 22 to extrude petals. The feeding section 21 extends through the fragrance collection tube 1 in a direction away from the ground to form a placement opening 211. The reagent box 4 supplies solvent into the feeding section 21 through the liquid supply nozzle 41. The extrusion section 22 is provided with a liquid outlet 221 near the ground, and the liquid outlet 221 is connected to the clarification chamber 7 through a liquid outlet pipe 2211. The upper surface of the liquid outlet 221 extends perpendicularly to the inner wall of the extrusion section 22, and the corner of the inner wall of the extrusion section 22 is provided with a rounded corner 223. The slag discharge section 23 is provided with a slag discharge trough 231 on the side near the ground, which allows the extruded petals to enter. The mixing chamber 6 is connected to the slag discharge trough 231 through a slag discharge pipe 232, and the slag discharge pipe 232 is connected to the mixing chamber through a flange. The mixing chamber 6 and the clarification chamber 7 are connected through a connecting pipe.

[0034] Reference Figure 2 Optionally, a first through hole 11 communicating with the feeding section 21 is provided on the outer wall of the incense collecting cylinder 1. The liquid dispensing nozzle 41 is inserted into the first through hole 11. A first sleeve 111 for fixing the liquid dispensing nozzle 41 is provided on the outer wall of the incense collecting cylinder 1 at the first through hole 11. A rubber sleeve (not shown in the figure) is provided on the outer wall of the liquid dispensing nozzle 41, and the liquid dispensing nozzle 41 is inserted into the first sleeve 111 through the rubber sleeve with an interference fit. Installing the liquid dispensing nozzle 41 through the first through hole 11 facilitates the setting of the nozzle, and the first sleeve 111 is used to fix the liquid dispensing nozzle 41.

[0035] Reference Figure 2 Optionally, a second through hole 12 communicating with the slag discharge section 23 is provided on the outer wall of the fragrance collection cylinder 1. A flushing nozzle 42 connected to the reagent tank 4 passes through the second through hole 12, with its opening facing the outer wall of the rotor 3. A second sleeve 121 for fixing the flushing nozzle 42 is provided on the outer wall of the fragrance collection cylinder 1 at the second through hole 12, and the connection between the flushing nozzle 42 and the second sleeve 121 is as described above. When the rotor 3 passes through the slag discharge section 23, most of the pressed petals fall into the pressing tank, while some petals adhere to the outer wall of the rotor 3. The flushing nozzle 42 washes the outer wall of the rotor 3, causing the petals to fall off, thereby keeping the surface of the rotor 3 clean.

[0036] Reference Figure 2 Optionally, the processing tank also includes a rinsing section 24. The inner wall of the rinsing section 24 is arc-shaped, with the center of rotation of the rotor 3 as the point and the radius from one corner of the rotor 3 to the center. The rinsing section 24 is located between the slag discharge section 23 and the feeding section 21. A third through hole 13 communicating with the rinsing section 24 is provided on the outer wall of the aroma collecting cylinder 1. A spray nozzle 43 communicating with the reagent box 4 passes through the third through hole 13. The opening of the spray nozzle 43 faces the outer wall of the rotor 3. A third sleeve 131 for fixing the spray nozzle 43 is provided on the outer wall of the aroma collecting cylinder 1 at the third through hole 13. The connection between the spray nozzle 43 and the third sleeve 131 is as described above. After passing through the slag discharge section 23, the rotor 3 enters the rinsing section 24. The spray in the rinsing section 24 sprays solvent onto the surface of the rotor 3. If the solvent is insoluble in water, water can also be used for rinsing, thereby rinsing the rotor 3 a second time, so that the petals detach from the surface of the rotor 3 and are mixed again with the newly fed petals in the feeding section 21 before entering the next step.

[0037] Reference Figure 2 Furthermore, a filter screen 222 for filtering petal residue is provided at the communication position between the liquid outlet 221 and the extrusion section 22. The filter screen 222 is a metal mesh with a pore size smaller than the volume of the petal residue. The liquid outlet 221 is funnel-shaped, and the liquid outlet pipe 2211 is connected to the end of the liquid outlet 221 near the ground. The funnel-shaped design of the liquid outlet 221 facilitates the discharge of the tissue fluid mixed with the solvent after pressing. The filter screen 222 is used to filter petal residue and prevent it from falling into the liquid outlet 221, thereby efficiently guiding the mixed liquid.

[0038] Reference Figure 2 Optionally, each of the three triangles of the rotor 3 has a connecting groove 31 along its radius. The barrier 32 is slidably connected in the connecting groove 31. An elastic element 33, which is a spring arranged along the length of the connecting groove 31, is provided in the connecting groove 31 to ensure that the barrier 32 always moves towards the inner wall of the incense collecting cylinder 1. The elastic element 33 is a spring. Through the action of the elastic element 33, the barrier 32 always extends away from the rotor 3, so that during the rotation of the rotor 3, the barrier 32 and the rotor 3 form a space that can drive the petals to move, so that the petals can move with the rotor 3. At the same time, the sliding of the barrier 32 can prevent the structure from getting stuck during the movement.

[0039] Reference Figure 2 Furthermore, the end of the barrier 32 furthest from the rotor 3 is provided with a chamfer 321. This makes the barrier 32 smoother when it comes into contact with the inner wall of the incense collecting cylinder 1, reducing wear on the end of the barrier 32.

[0040] Reference Figure 2Furthermore, a limiting block 322 is provided on the outer wall of the barrier 32, and a limiting groove 311 is provided on the rotor 3 along the length direction of the barrier 32 for the limiting block 322 to move. The limiting block 322 cooperates with the limiting groove 311 to restrict the transition displacement of the barrier 32, prevent the limiting block 322 from disengaging from the rotor 3, and also increase the stability of the barrier 32 during movement.

[0041] Reference Figure 2 Furthermore, the mixing chamber 6 is equipped with a stirring mechanism (not shown in the figure) for stirring the internal mixture. The stirring mechanism is generally a shaft with blades that rotates inside the mixing chamber 6. The rotation of the shaft is driven by a motor. Since there are many existing methods, they will not be described in detail.

[0042] Optionally, a secondary mixing chamber 6 can be added outside the mixing chamber 6 to filter the petals. The secondary mixing chamber 6 has the same structure as the mixing chamber 6. The filtered liquid is stirred in the secondary mixing chamber 6 to form an emulsion, and then the emulsion is lifted to the clarification chamber 7. Under the action of gravity, it is separated into two liquid phases and discharged from different outlets. Since the emulsion is relatively viscous, when lifting the emulsion from the mixing chamber 6 to the clarification chamber 7, a combination of pipes and pumps is generally used to transport the emulsion.

[0043] Reference Figure 2 Optionally, a feeding hopper 14 communicating with the placement opening 211 is provided on the side of the incense collection tube 1 away from the ground. The feeding hopper 14 is threadedly connected to the placement opening 211 of the incense collection tube 1. This is used to continuously allow petals to enter the incense collection tube 1.

[0044] The implementation principle of the jasmine fragrance extraction device in this application embodiment is as follows:

[0045] Petals are continuously fed into the feeding section 21 of the processing tank through the placement port 211. The rotor 3 rotates and, in conjunction with the blocking member 32, moves the petals. As the petals gradually transition from the feeding section 21 to the pressing section 22 with the rotor 3, the distance between the side wall of the rotor 3 and the inner wall of the processing tank gradually decreases. This allows the rotor 3 to press the petals in conjunction with the wall of the fragrance collection cylinder 1. Since there is a liquid supply nozzle 41 in the feeding section 21 that supplies solvent, some tissue fluid seeps out and dissolves in the solvent after the petals are squeezed. The mixed liquid flows into the liquid outlet 221 and then flows into the clarification chamber 7 through the liquid outlet pipe 2211. The pressed petals continue to be pushed into the slag discharge section 23 by the rotor 3 and the blocking member 32. Under the action of gravity, they fall from the slag discharge trough 231 into the mixing chamber 6 for soaking treatment, and the upper liquid is sent to the clarification chamber 7. At the same time, the petals adhering to the wall of the rotor 3 will be washed by the solution when it rotates to the liquid supply nozzle 41 again, thus making them easy to fall out.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
