Description

Technical Field

[0001] The present invention relates to the technical field of essential oil extraction, and more particularly to a rose essence extraction system and an extraction method thereof. Background Art

[0002] As a core carrier of natural fragrances and functional ingredients, rose essential oil's aroma persistence, chemical stability, and compositional diversity directly impact its application value in high-end fragrances, cosmetics, and natural medicine. Currently, the industry's mainstream rose essential oil extraction technologies—traditional distillation and crushing extraction—distinctly differ in their technical approaches, product characteristics, and applicable scenarios. Companies must flexibly select processes based on the quality requirements of their target essential oils.

[0003] The traditional distillation method indirectly heats the petals through water vapor, using the physical barrier of the cell wall to retain some large-molecule volatile components (such as sesquiterpenes and esters). The extracted essential oils have the advantages of strong lasting aroma, high chemical stability and natural certification. This type of essential oil has a high content of low volatility and high boiling point components (such as citronellol and phenylethanol), and evaporates slowly at room temperature, making it suitable for use as a perfume fixative or long-lasting fragrance product.

[0004] The post-crushing extraction method destroys the cell structure through mechanical crushing or solvent-assisted means, releasing more small-molecule volatile components (such as monoterpenes and aldehydes), making the essential oil aroma more layered and suitable for the production of high-end fragrances or complex fragrance cosmetics.

[0005] Of the two current processes, the traditional distillation method has low distillation extraction efficiency because the petals are not crushed and are held together by water molecules during distillation. The post-crushing extraction method requires the petals to be crushed using crushing equipment before distillation extraction. The existing extraction technologies of the two processes are limited by the single function of the equipment and the inefficiency of process switching.

[0006] In order to solve the above problems, a rose essence extraction system and an extraction method are proposed. Summary of the Invention

[0053] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0054] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0055] In the present invention, unless otherwise specified, directions such as "up" and "down" are generally used with respect to the directions shown in the drawings, or with respect to the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "left" and "right" are generally used with respect to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.

[0056] For examples, see Figure 1 - Figure 12 A rose essence extraction system and method thereof includes a distillation kettle 1, wherein a material barrel 2 with a horizontal axis is provided inside the distillation kettle 1, and a turning mechanism 3 is coaxially provided inside the material barrel 2, and a switching mechanism 4 is provided at the axis of the turning mechanism 3, and both the switching mechanism 4 and the turning mechanism 3 are detachable from the material barrel 2;

[0057] A servo motor 5 is provided at one end of the distillation kettle 1, and the output shaft of the servo motor 5 is correspondingly plugged into the switching mechanism 4;

[0058] The turning mechanism 3 includes a turning assembly 301 matched with the material barrel 2 and a crushing assembly 302 arranged in the turning assembly 301;

[0059] The material barrel 2 is a horizontally arranged cylinder, and a flow hole 201 and a drainage hole 202 are opened on the circumferential side wall of the material barrel 2. A rolling part 203 is provided at the bottom of the inner wall of the material barrel 2, and the drainage holes 202 are provided at both ends of the rolling part 203;

[0060] When the switching mechanism 4 does not interfere with the crushing assembly 302 , there is a distance between the crushing assembly 302 and the inner wall of the material barrel 2 . When the switching mechanism 4 interferes with the crushing assembly 302 , the crushing assembly 302 presses against the inner wall of the material barrel 2 to crush the rose petals.

[0061] The distillation kettle 1 is a prior art, which includes a housing, a liquid inlet valve, a liquid discharge valve, and a distillation tube. The housing has the function of heating and distillation. First, rose petals are placed in the material barrel 2, and then hot water is added to the distillation kettle 1, and the hot water needs to cover the material barrel 2. By heating the water in the distillation kettle 1, the distillation and extraction of rose petal essential oil is achieved. When distilling and extracting the essential oil, because the rose petals in the material barrel 2 are bonded together by water molecules, when distilling, the molecules distilled from the petals can only be released through the side where the petals are not bonded, resulting in a slow efficiency of essential oil extraction. The present invention drives the switching mechanism 4 to rotate by the servo motor 5, thereby driving the turning mechanism 3 to rotate, thereby causing the turning component 301 to drive the rose petals in the material barrel 2 to stir. When the stirred rose petals are stirred in the water, the bonded petals will be separated, thereby allowing the molecules distilled from the petals to evaporate from both sides, thereby improving the efficiency of rose essential oil extraction.

[0062] According to the requirements of the rose essential oil refining process, the servo motor 5 is controlled to rotate in the opposite direction, and the working state of the crushing component 302 is switched by rotating clockwise and counterclockwise. Figure 7 As shown, it rotates clockwise, and the crushing component 302 is in a contracted state, that is, there is a distance between the crushing component 302 and the inner wall of the material barrel 2. The switching mechanism 4 drives the turning component 301 to rotate clockwise, and the crushing component 302 will not crush and crush the rose petals on the inner wall of the material barrel, that is, the clockwise rotation is a traditional distillation method. However, compared with the traditional distillation method, it drives the rose petals in the material barrel 2 to be turned and stirred by the turning component 301, so that the petals that are stuck together are separated, thereby improving the efficiency of rose essential oil extraction.

[0063] At the same time, if Figure 9As shown, it rotates counterclockwise. When the servo motor 5 drives the switching mechanism 4 to rotate counterclockwise, it pushes the crushing assembly 302, so that the crushing assembly 302 moves to fit the inner wall of the material barrel 2, and through the resistance force, the positions of the switching mechanism 4 and the turning assembly 301 are relatively stationary, so that the turning assembly 301 rotates counterclockwise with the switching mechanism 4, thereby driving the rose petals in the material barrel 2 to be stirred, and the rose petals are pushed to the inner wall of the material barrel 2 through the turning assembly 301, so that the crushing assembly 302 can better crush the rose petals, thereby destroying the cell structure of the rose petals, making it easier for the internal molecules to be distilled out to generate essential oils, and the aroma of the essential oils is richer.

[0064] Among them, the material barrel 2 allows the rose petals and hot water inside it to mix through the circulation hole 201 and the drainage hole 202, thereby realizing the distillation of the rose petals. Moreover, through the setting of the drainage hole 202, after the extraction of the rose petal essential oil is completed, when the hot water in the distillation kettle 1 is discharged outward, the hot water in the material barrel 2 can be discharged through the drainage hole 202, thereby avoiding the residual hot water in the material barrel 2 after the distillation is completed.

[0065] Furthermore, the crushing portion 203 on the material barrel 2 is an area on the barrel where the flow holes 201 and the drainage holes 202 are not provided, so that the crushing component 302 can better crush the rose petals when crushing them, thereby making the molecules in the petals more easily volatilized.

[0066] The turning assembly 301 is composed of a driving shaft tube 301a and a turning blade 301b, and the switching mechanism 4 is arranged inside the driving shaft tube 301a;

[0067] The material turning blades 301b are arranged in an arc shape, and are arranged in a ring array on the circumferential outer wall of the driving shaft tube 301a.

[0068] When the servo motor 5 drives the turning assembly 301 to rotate clockwise through the switching mechanism 4, the concave inner surface of the arc-shaped turning blade 301b pushes the water flow and turns the rose petals, so that the attached rose petals are separated under the action of the water flow.

[0069] When the servo motor 5 drives the turning component 301 to rotate counterclockwise through the switching mechanism 4, the outer arch surface of the arc-shaped turning blade 301b pushes the water flow and pushes the rose petals toward the inner wall of the material barrel 2 through the inner concave surface and the arc surface of the outer arch, so that the crushing component 302 can crush the rose petals.

[0070] A plurality of baffles 301c are provided in an annular array on the inner wall of the drive shaft tube 301a, and the gaps between the baffles 301c form a switching area 301d of the switching mechanism 4;

[0071] The switching mechanism 4 includes a shaft 401 rotatably mounted in the driving shaft tube 301a, and a plurality of push blocks 402 arranged on the circumferential side wall of the shaft 401;

[0072] The pushing block 402 is movably disposed in the switching area 301d.

[0073] A limiting surface 403 and a pushing arc surface 404 are provided on the pushing block 402 . The limiting surface 403 corresponds to the blocking bar 301 c , and the pushing arc surface 404 corresponds to the pushing rolling assembly 302 .

[0074] like Figure 7 As shown, when the servo motor 5 drives the shaft 401 to rotate clockwise, it drives the push block 402 to move in the switching area 301d, so that the limiting surface 403 on the push block 402 contacts the baffle 301c, thereby driving the drive shaft tube 301a to rotate, thereby causing the multiple turning blades 301b in the annular array to rotate, driving the rose petals to be stirred and separated by the water flow.

[0075] like Figure 9 As shown, when the servo motor 5 drives the shaft 401 to rotate counterclockwise, the push block 402 pushes the crushing assembly 302, causing the crushing assembly 302 to move, thereby pressing against the inner wall of the material barrel 2, crushing and crushing the rose petals in the material barrel 2, and simultaneously distilling and extracting the essential oil.

[0076] The turning blade 301b has an internal accommodating chamber 301e, and the rolling assembly 302 is arranged in the accommodating chamber 301e. The accommodating chamber 301e is connected to the switching area 301d, and a strip groove 301f is formed on the outer arch surface of the accommodating chamber 301e near the end of the material barrel 2;

[0077] The rolling assembly 302 includes an inner plate 302a disposed in the accommodating cavity 301e, a bracket 302b disposed on one side of the inner plate 302a and close to one end of the material barrel 2, and a rolling roller 302c rotatably mounted on the bracket 302b.

[0078] The strip groove 301f, the accommodating chamber 301e and the switching area 301d are connected, and the inner plate 302a is movably installed in the accommodating chamber 301e. When there is a distance between the rolling roller 302c and the inner wall of the material barrel 2, the end of the inner plate 302a away from the inner wall of the material barrel 2 is located in the switching area 301d. The bracket 302b is fixedly connected to the inner plate 302a, and the rolling roller 302c is installed after passing through the strip groove 301f, so that the rolling roller 302c can roll the rose petals. It should be noted that the end of the turning blade 301b is in contact with the inner wall of the material barrel 2, so that it can drive the rose petals between the turning blades 301b of the annular array to move when rotating clockwise, and can more evenly roll and crush the rose petals in each area when rotating counterclockwise.

[0079] One end of the inner plate 302a close to the switching area 301d is in an arc shape, so that when the shaft 401 drives the pushing block 402 to rotate counterclockwise, the pushing arc surface 404 can better push the inner plate 302a to move toward the inner wall of the material barrel 2.

[0080] A baffle 301g is provided at one end of the accommodating cavity 301e close to the switching area 301d, and a spring slot 302d is provided at one end of the inner plate 302a close to the switching area 301d;

[0081] The rolling assembly 302 further includes a return spring 302e disposed in the spring slot 302d. One end of the return spring 302e abuts against the baffle 301g, and the other end of the return spring 302e abuts against the inner wall of the spring slot 302d.

[0082] Under the action of the return spring 302e, in the initial state, one end of the inner plate 302a is located in the switching area 301d, and there is a gap between the rolling roller 302c and the inner wall of the material barrel 2. When rotating counterclockwise, the pushing arc surface 404 of the pushing block 402 pushes the inner plate 302a to be located at one end of the switching area 301d, so that the inner plate 302a contracts into the accommodating chamber 301e. When the inner plate 302a contracts, the return spring 302e is compressed, and the bracket 302b drives the rolling roller 302c to press against the inner wall of the material barrel 2. It should be noted that when the crushing roller 302c presses the inner wall of the material barrel 2, the pushing arc surface 404 of the pushing block 402 cannot pass over the end of the inner plate 302a, and thus it will be in a dead state, thereby causing the inner plate 302a to rotate, thereby driving the turning blade 301b to rotate, and during rotation, the resistance of the water will cause the rotational force to increase, thereby increasing the force of the pushing block 402 against the inner plate 302a, and then making the crushing roller 302c have a greater pressing force on the inner wall of the material barrel 2, thereby making it easier to crush the rose petals.

[0083] A first through hole 301 h is formed on the turning blade 301 b , and a second through hole 302 f is formed on the inner plate 302 a . The first through hole 301 h corresponds to the second through hole 302 f .

[0084] Under the action of the return spring 302e, the first through hole 301h and the second through hole 302f correspond to each other, that is, when the turning blade 301b rotates clockwise, water can flow through the first through hole 301h and the second through hole 302f, so that the force required for its rotation is smaller, thereby saving energy consumption.

[0085] When rotating counterclockwise, the pushing block 402 pushes the inner plate 302a to move, causing the first through hole 301h and the second through hole 302f to be misaligned, so that the through hole is blocked, and an inner concave hole is formed on the turning blade 301b with the first through hole 301h, so that when the turning blade 301b rotates, when water flows through the inner concave hole formed by the first through hole 301h on the outer arch surface, water flow resistance is generated, which increases its rotational force, so that the rolling roller 302c has better rolling pressure when rolling the rose petals.

[0086] The material turning assembly 301 further includes a material dragging plate 301 i disposed at one end of the material turning blade 301 b close to the servo motor 5 , and the material dragging plate 301 i matches the inner wall of the material barrel 2 .

[0087] The setting of the drag plate 301i enables the rose petals placed in the area of the turning blade 301b to be removed at one time by disassembling the turning component 301 after distillation and refining, thus saving a lot of manpower.

[0088] One end of the shaft 401 is provided with a rotation-stop groove 405 corresponding to the output shaft of the servo motor 5, and the other end of the shaft 401 is provided with a center groove 406;

[0089] A sealing door 6 is provided at one end of the distillation kettle 1 away from the servo motor 5 , and a central rod 601 corresponding to the central groove 406 is provided at the axis of the sealing door 6 .

[0090] The switching mechanism 4 is connected to the output shaft of the servo motor 5 through the anti-rotation groove 405 on the shaft 401, thereby realizing the detachability of the flipping mechanism 3 and the switching mechanism 4. At the same time, the center rod 601 on the sealing door 6 is connected to the center groove 406 at the other end of the shaft 401, so that the servo motor 5 has sufficient stability when driving the flipping mechanism 3 to rotate.

[0091] Two locking blocks are rotatably installed at the end of the sealing door 6 on the distillation kettle 1, and the two locking blocks are respectively arranged at both ends of the sealing door 6. The locking of the sealing door 6 is achieved by the locking blocks. The sealing door 6 is rotatably installed through the rotating shaft, and the sealing door 6 can move along the axial direction of its rotating shaft to achieve the docking and separation of the center rod 601 and the center groove 406. It should be noted that when the sealing door 6 moves along the axial direction of the rotating shaft away from the closing direction to the end of the rotating shaft, the center rod 601 is located outside the distillation kettle 1, and the sealing door 6 is not affected by the limiting effect of the locking blocks when rotating at this time, and under the action of the center, the sealing door 6 rotates to open.

[0092] S1. Place rose petals in the material cylinder 2 in the distillation kettle 1, and add hot water into the distillation kettle 1 to ensure that the hot water covers the material cylinder 2;

[0093] S2. Select the rotation direction of the servo motor 5 according to the process requirements and proceed to S3 or S4;

[0094] S3, rotate clockwise, the switching mechanism 4 drives the turning mechanism 3 to rotate clockwise, and the turning assembly 301 drives the rose petals in the material barrel 2 to stir, so that the petals that fit together are separated and the essential oil is distilled and extracted;

[0095] S4, rotate counterclockwise, push the crushing assembly 302 to press against the inner wall of the material barrel 2 through the switching mechanism 4, crush the rose petals, and distill and extract the essential oil at the same time;

[0096] S5. After the distillation is completed, the drain valve of the distillation kettle 1 is opened to drain the hot water. The material turning component 301 is disassembled and the rose petal residue in the material barrel 2 is taken out at one time using the drag plate 301i.

[0097] In all the schemes mentioned above, the connection between the two parts can be selected according to actual conditions by welding, bolt and nut connection, bolt or screw connection or other well-known connection methods, which will not be listed here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the present invention have been shown and described, it can be understood by those skilled in the art that various changes, modifications, substitutions and deformations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
