Description

Technical Field

[0001] This utility model relates to the field of natural product extraction and separation technology, and in particular to an extraction device for processing rose essential oil. Background Technology

[0002] Solvent extraction is a crucial process for extracting rose absolutes and concretes, particularly suitable for preserving heat-sensitive aromatic components. Traditional methods typically employ static or stirred extraction, mixing rose petals with organic solvents (such as hexane or petroleum ether) and utilizing the solvent's selective solubility for essential oil molecules to achieve separation. However, static extraction suffers from low mass transfer efficiency, long extraction times (usually exceeding 6 hours), and high solvent consumption. While mechanical stirring accelerates mixing, it can lead to excessive petal breakage, increasing the dissolution of waxes and pigments, thus affecting subsequent purification. Furthermore, high-temperature solvent concentration may result in the loss of some volatile aroma components, reducing the quality of the absolute. To optimize the process, the industry has gradually introduced dynamic extraction systems (such as rotary extraction tanks), which enhance solvent permeability through gentle mechanical movement while reducing thermal damage. However, balancing extraction efficiency with component retention remains a technical challenge. Controlling solvent residues and developing environmentally friendly solvents are also key research areas in this field to meet the safety standards for cosmetic and food-grade essential oils.

[0003] Traditional solvent extraction processes for rose essential oil generally employ stirred extraction tanks, relying on mechanical stirring to achieve solid-liquid mixing. This method suffers from core technical bottlenecks such as low mass transfer efficiency and incomplete extraction. Because the stirring action is limited to the area around the impeller blades, dead zones easily form, leading to insufficient contact between the solvent and petals, resulting in long extraction times and large yield fluctuations. Furthermore, the shear force generated by high-speed stirring can damage the petal cell structure, releasing impurities such as waxes and chlorophyll, increasing the burden on subsequent purification. Simultaneously, frictional heat may accelerate the oxidative degradation of heat-sensitive aromatic components (such as phenylethyl alcohol), affecting the quality of the essential oil.

[0004] Taking the patent "A Rose Essential Oil Extraction Device" (application number: CN202420521296.0) as an example, this device uses a distillation method. It drives a rotating sieve cylinder to tumble the rose petals inside, increasing the contact area between water vapor and the petals and improving extraction efficiency. However, this device focuses on optimizing the contact between petals and water vapor during distillation, without addressing issues such as low solid-liquid mass transfer efficiency, impurity dissolution, and the protection of heat-sensitive components in solvent extraction. In solvent extraction scenarios, its rotating sieve cylinder structure cannot solve the problem of insufficient mixing between solvent and petals, and it is difficult to avoid excessive petal breakage and loss of heat-sensitive components due to stirring-like actions. It is evident that existing technologies still have many shortcomings in rose essential oil solvent extraction processes, and innovative equipment is urgently needed to solve these long-standing technical bottlenecks that have hindered the industry's development.

[0016] The extraction equipment for processing rose essential oil provided by this utility model has the following beneficial effects:

[0017] In this invention, the extraction equipment for processing rose essential oil solves the problem of low solid-liquid mass transfer efficiency in traditional static extraction and stirred extraction by fundamentally addressing the issue of low efficiency through a tilted and rotatable tank frame design. Unlike traditional stirred extraction tanks that rely solely on the area around the paddles for mixing, which easily creates dead zones, the tank frame of this equipment is tilted and mounted on the frame, continuously rotating with the drive unit. This allows the rose petals and organic solvent inside the extraction tank to achieve comprehensive and dynamic contact without dead zones under the combined action of centrifugal force and gravity.

[0018] This unique motion pattern breaks down the mass transfer barrier between the solid and liquid phases, greatly accelerating the diffusion rate of essential oil molecules from the petals into the solvent and avoiding incomplete extraction due to insufficient local contact. Compared to the extraction time of traditional static extraction, this equipment can significantly shorten the extraction cycle thanks to its efficient mass transfer. In addition, the rotation of the tank rack eliminates the need for high-intensity stirring, effectively preventing excessive damage to the petal cell structure and reducing the dissolution of impurities such as waxes and pigments, further improving the quality of the essential oil. This provides a practical and innovative solution for the efficient and green upgrading of rose essential oil extraction technology. Attached Figure Description

[0030] Example 1

[0031] Please see Figure 1 This utility model provides an extraction device for processing rose essential oil. Commonly used extraction devices for processing rose essential oil mainly include steam distillation, solvent extraction, and supercritical CO2 extraction. Among them, the solvent extraction method is used for the extraction of rose absolute or condensate. The solvent extraction method uses organic solvents such as petroleum ether and hexane to dissolve the wax and aromatic molecules in rose. After evaporating the solvent, a condensate is obtained, which is then purified by alcohol extraction to obtain absolute.

[0032] Solvent extraction involves pretreatment, maceration, filtration, evaporation and concentration, alcohol extraction, and freeze filtration. Maceration involves soaking petals in a solvent such as hexane in a sealed container for several hours, allowing the solvent to penetrate the cells and dissolve the essential oil. However, static maceration suffers from low mass transfer efficiency and long extraction time; while stirred maceration can easily lead to excessive petal breakage, increasing the dissolution of waxes and pigments, and affecting subsequent purification results.

[0033] Therefore, in this embodiment, an extraction device is provided that improves mass transfer efficiency while avoiding excessive breakage of the petals by rotating the extraction tank itself to ensure full contact between the petals and the solvent.

[0034] Please see Figure 1 and Figure 2 In this embodiment, the extraction equipment includes a frame 100, a power mechanism 300, and a barrel rack 200 disposed on the frame 100. The frame 100 includes a base 110 and a first rotating seat 120 and a second rotating seat 130 disposed on the base 110. A rotatable barrel rack 200 is provided between the first rotating seat 120 and the second rotating seat 130. The power mechanism 300 includes a drive member 310 that is pulverically connected to the barrel rack 200. The drive member 310 is placed by a mounting bracket 121 disposed on the side of the first rotating seat 120. The barrel rack 200 is also provided with a receiving space 210, and a first fastener and a second fastener for fixing an extraction barrel 400 to the receiving space 210. The first fastener is used to fasten the barrel body of the extraction barrel 400, and the second fastener is used to fasten the end of the extraction barrel 400. The barrel rack 200 is installed on the frame 100 at an angle.

[0035] In use, the sealed extraction tank 400 is installed on the tank frame 200 using the first and second fasteners. Then, the drive unit 310 is activated, causing the tank frame 200 to rotate around the axis between the first rotating base 120 and the second rotating base 130. Because the tank frame 200 is tilted, the petals and solvent inside the extraction tank 400 continuously tumble and flow during rotation, allowing for more thorough contact between the petals and solvent and effectively improving mass transfer efficiency. Furthermore, compared to agitated extraction, this method relying on tank rotation avoids excessive mechanical damage to the petals, preventing excessive petal breakage and reducing the dissolution of waxes and pigments, thus ensuring that subsequent purification is not affected and achieving a highly efficient and high-quality rose essential oil extraction process.

[0036] Further, please see Figure 1 The first rotatable base 120 includes a first support leg 122 and a second support leg 123; the first support leg 122, the second support leg 123 and the base 110 form a triangular structure; wherein, the top of the first support leg 122 and the second support leg 123 is provided with a mounting plate 124; wherein, the second rotatable base 130 has the same structural configuration as the first rotatable base 120.

[0037] In use, the first rotating base 120 and the second rotating base 130, with their unique triangular structures, provide stable support for the bucket rack 200. The mounting plate 124 ensures a more secure and reliable connection between the bucket rack 200 and the rotating base, keeping the bucket rack 200 stable during rotation and preventing it from wobbling or shifting.

[0038] Since the second rotor 130 has the same structure as the first rotor 120, the two work together to further improve the stability of the entire device during operation, thereby ensuring that the mixing process of petals and solvent is smooth and efficient during the tilting and rotation of the extraction tank 400, and always maintaining a good extraction effect.

[0039] Furthermore, the top of the first rotary seat 120 and the second rotary seat 130 are respectively provided with a first bearing seat 125 and a second bearing seat 131.

[0040] Furthermore, the bucket rack 200 includes a first mounting rod 241 and a second mounting rod 242, as well as a first connecting rod 243 and a second connecting rod 247 connecting the first mounting rod 241 and the second mounting rod 242.

[0041] Furthermore, the outer sides of the first connecting rod 243 and the second connecting rod 247 are respectively provided with a first connecting member 244 and a second connecting member 248; the two ends of the bucket frame 200 are respectively connected to the first rotating seat 120 and the second rotating seat 130 through the first connecting member 244 and the second connecting member 248; and the center lines of the first rotating seat 120, the second rotating seat 130, the first connecting member 244 and the second connecting member 248 are on the same horizontal axis.

[0042] Please see Figure 1 In use, the first bearing seat 125 and the second bearing seat 131 provide good support and guidance for the rotation of the barrel frame 200, reducing friction and resistance during rotation. The first mounting rod 241 and the second mounting rod 242 are connected by the first connecting rod 243 and the second connecting rod 247 to form a stable frame structure, ensuring the overall strength and stability of the barrel frame 200. The first connecting piece 244 and the second connecting piece 248 serve as transmission connection components between the barrel frame 200 and the rotating seat, enabling the barrel frame 200 to rotate synchronously with the rotation of the first rotating seat 120 and the second rotating seat 130. Since the centerlines of the first rotating seat 120, the second rotating seat 130, the first connecting piece 244, and the second connecting piece 248 are on the same horizontal axis, the stability and accuracy of the barrel frame 200 during rotation are ensured, avoiding wobbling or eccentricity caused by inconsistent centerlines, further ensuring the uniformity of the mixing of petals and solvent, thereby improving the extraction efficiency and quality of rose essential oil.

[0043] Further, please see Figure 3An auxiliary stirring element 410 is fixedly installed on the inner wall of the extraction tank 400. During use, the auxiliary stirring element 410 can cooperate with the rotation of the tank frame 200 to further enhance the mixing effect of the petals and solvent in the extraction tank 400. The auxiliary stirring element 410 is arranged in an arc-shaped plate shape and is spaced apart on the tank wall. When the extraction tank 400 rotates, it can use centrifugal force and fluid dynamics principles to push the material near the tank wall towards the center of the tank, avoiding the accumulation of material on the tank wall and ensuring that the petals and solvent can fully contact and mix throughout the extraction tank 400.

[0044] Meanwhile, the auxiliary stirring component 410 can also break up larger petal clumps, allowing the petals to come into contact with the solvent in a finer state, accelerating the dissolution rate of the active ingredients, thereby achieving a higher extraction rate in a shorter time, and helping to improve the consistency and purity of rose essential oil components.

[0045] Furthermore, the first connector 244 includes a connecting body 245 and a connecting shaft 246 disposed on the connecting body 245; the first connector 244 and the second connector 248 have the same structural configuration; the first connector 244 and the second connector 248 are respectively connected to the first bearing seat 125 and the second bearing seat 131 via the connecting shaft 246.

[0046] Furthermore, the power mechanism 300 also includes a reducer 320 and a coupling 330; the driving component 310 is a motor; the motor is connected to the reducer 320 in a transmission connection, and the reducer 320 is connected to the first connecting component 244 via the coupling 330 and the first bearing seat 125 in a transmission connection.

[0047] In use, by starting the motor, the motor's power is adjusted by the reducer 320 and transmitted to the first connecting member 244 via the coupling 330. This, in turn, drives the connecting shaft 246 of the first connecting member 244 to rotate within the first bearing seat 125. Since the first connecting member 244 and the second connecting member 248 have identical structures and their axes are on the same horizontal axis, the rotation of the first connecting member 244 causes the entire barrel frame 200 to rotate around this axis, thereby rotating the extraction barrel 400. This ensures that the petals and solvent within the extraction barrel 400 are fully mixed, completing the extraction process of rose essential oil. Throughout the entire operation, the reducer 320 accurately controls the rotation speed of the barrel frame 200, ensuring that the petals and solvent are mixed at an appropriate speed. This guarantees the mixing effect without excessively damaging the petals due to excessive rotation speed, thus affecting the quality of the rose essential oil.

[0048] Further, please see Figure 1 and Figure 2The first fastener includes a first fixed limiting plate 221 and a second fixed limiting plate 222 arranged at intervals; the two ends of the first fixed limiting plate 221 and the second fixed limiting plate 222 are respectively fixedly connected to the first mounting rod 241 and the second mounting rod 242.

[0049] Furthermore, both the first fixed limiting plate 221 and the second fixed limiting plate 222 have a protruding limiting space at the end away from the first mounting rod 241 and the second mounting rod 242, so as to limit the installation range of the extraction tank 400.

[0050] Furthermore, the first fastener also includes a movable limiting plate 223 detachably disposed on the other side of the first mounting rod 241 and the second mounting rod 242; the movable limiting plate 223 is disposed between the first fixed limiting plate 221 and the second fixed limiting plate 222; the movable limiting plate 223 has a protruding limiting space at one end away from the first mounting rod 241 and the second mounting rod 242, so as to limit the installation range of the extraction tank 400.

[0051] Furthermore, one end of the second fastener 230 is fixedly connected to the opening of the extraction tank 400, and the other end is fixedly connected to the first connecting rod 243.

[0052] In use, the extraction tank 400 is placed within the limiting space formed by the first fixed limiting plate 221 and the second fixed limiting plate 222, and the end of the extraction tank 400 is fixed to the tank frame 200 by the second fastener 230. Then, the movable limiting plate 223 is installed between the first fixed limiting plate 221 and the second fixed limiting plate 222, and fixed by the first mounting rod 241 and the second mounting rod 242. This ensures that the extraction tank 400 is stably installed on the tank frame 200, preventing shaking or displacement during use, ensuring smooth extraction, and improving the stability and reliability of the extraction operation. Simultaneously, this installation method makes the disassembly and replacement of the extraction tank 400 convenient. When cleaning the extraction tank 400 or replacing it with a different size extraction tank 400, simply remove the movable limiting plate 223 and release the second fastener 230 from fixing the end of the extraction tank 400 to easily remove it, greatly facilitating actual operation.

[0053] Further, please see Figure 1The mounting plates 124 of the first rotary seat 120 and the second rotary seat 130 are respectively provided with a first hinge 510 and a second hinge 520. A protective rod 530 that can rotate based on the first rotary seat 120 and the second rotary seat 130 is provided through the first hinge 510 and the second hinge 520. The two ends of the protective rod 530 are respectively connected to the first hinge 510 and the second hinge 520 to form a stable connection structure.

[0054] When extraction is required, the protective rod 530 can be rotated to a suitable position to form a protective zone around the tank rack 200 and extraction tank 400, preventing operators from accidentally approaching the operating extraction equipment and ensuring personnel safety. Furthermore, when operation of the extraction tank 400 or tank rack 200 is required, the protective rod 530 can be rotated to a position that does not interfere with the operation, ensuring unimpeded work. The surface of the protective rod 530 can also be provided with anti-slip textures, facilitating better force application during rotation and improving ease of use.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
