Abstract
Description
Technical Field
[0001] This utility model relates to the field of essential oil processing technology, specifically to an extraction device for essential oil processing. Background Technology
[0002] Essential oils, as volatile substances with aromatic scents extracted from plants, have a wide and important application in many fields such as cosmetics, medicine, food, and fragrance. With the increasing demand for natural products, the extraction technology of essential oils has also received increasing attention. The quality of the essential oil extraction process directly affects the quality, yield, and production cost of the essential oil. Therefore, the development of efficient and high-quality essential oil extraction equipment has important practical significance.
[0003] Currently, the specific working process of essential oil extraction equipment is as follows: First, the plant raw material is placed in a pressing container for mechanical pressing, releasing the mixture of essential oil and residue into a collection tank. Then, the mixture needs to be manually transferred to a separate filtration device, where the essential oil is separated from solid impurities through static or low-speed filtration. This step-by-step operation typically consists of separate pressing and filtration units, connected by pipes or manual transfer. Extraction and filtration are performed in separate steps, requiring multiple material transfers, which not only increases labor costs but also extends the overall processing cycle, making it difficult to adapt to the needs of large-scale production. Relying solely on simple... The traditional filtration method makes it difficult to fully separate essential oils from residues, resulting in low purity of the extracted essential oils, which often contain a large number of solid impurities, affecting the quality and subsequent use of the essential oils. On the other hand, the device lacks temperature control, and cannot adjust the temperature of the extraction environment according to the characteristics of different essential oils (such as heat sensitivity, viscosity, etc.). When extracting heat-sensitive essential oils, unsuitable temperatures can easily lead to the volatilization and loss of essential oil components. When processing high-viscosity raw materials, the high viscosity results in poor flowability of the essential oils and low extraction efficiency. Therefore, we propose an extraction device for essential oil processing. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-5 This embodiment provides a technical solution: an extraction device for essential oil processing, including a support 1, a control switch 8 on the right side of the support 1, the input end of the control switch 8 being electrically connected to an external power source, an outer shell 3 inside the support 1, an essential oil discharge pipe at the lower end of the outer shell 3, and a pressing mechanism 2.
[0024] Pressing mechanism 2: It includes a pressing cylinder 21, a filter cylinder 22, a jacket 23, and a pressing plate 26. The pressing cylinder 21 is fixedly connected to the inside of the outer shell 3. The upper ends of the outer shell 3 and the pressing cylinder 21 are both hinged to material doors 5 (the upper ends of the outer shell 3 and the pressing cylinder 21 are both provided with door openings, and the upper ends of the door openings are hinged to material doors 5; the edges of the material doors 5 are provided with rubber sealing strips; door locks are provided between the lower ends of the outer shell 3 and the pressing cylinder 21 and the adjacent material doors 5, and the door locks adopt a conventional closing structure to realize the locking and opening of the material doors 5). The lower end of the outer shell 3 is hinged to a drain door 7 (the edge of the drain door 7 is provided with a rubber sealing ring, and the lower end of the drain door 7 and the lower end of the outer shell 3 are provided with a mechanical lock). The mechanical lock is a conventional mechanical lock in existing technology, mainly composed of a lock body, a bolt, a latch, a keyhole, and a spring structure. The lock body is fixedly installed at the lower end of the outer casing 3, and the bolt can extend and retract within the lock body, cooperating with the latch fixed at the lower end of the drain door 7 to achieve locking. The bottom wall of the pressing cylinder 21 has evenly distributed filter holes 211. The filter cylinder 22 is rotatably connected to the lower side of the pressing cylinder 21. The bottom wall of the filter cylinder 22 is threadedly connected to the bottom plate 6. The pressing cylinder 21 is configured to cooperate with the filter holes 211 (the filter holes 211 are all located inside the circular path formed at the upper end of the pressing cylinder 21, that is, the essential oil flowing out from the filter holes 211 enters the interior of the pressing cylinder 21). The pressing mechanism 2 also includes a driven gear 27 and a gear 28. The driven gear 27 is fixedly connected to the... The upper outer arc surface of the filter cylinder 22 has a gear 28 inside the outer casing 3, which meshes with the driven gear 27 (a baffle with a trapezoidal structure is provided on the upper outer arc surface of the filter cylinder 22 to prevent the essential oil discharged from the filter cylinder 22 from splashing). The outer casing 3 has a mounting plate 9 inside, and the gear 28 is rotatably connected to the mounting plate 9 via a rotating shaft. A motor 10 is mounted on the upper side of the mounting plate 9, and the output shaft of the motor 10 is fixedly connected to the center of the upper end face of the rotating shaft. The input end of the motor 10 is electrically connected to the output end of the control switch 8. The jacket 23 is located inside the outer casing 3 and is installed in conjunction with the pressing cylinder 21 (a temperature detector can be installed on the outer arc surface of the outer casing 3, with the temperature probe of the temperature detector extending into the interior of the outer casing 3 and close to the pressing cylinder 21). The outer arc surface of one end of the jacket 23 is in contact with the temperature. The worker judges the temperature of the pressing cylinder 21 by observing the temperature displayed by the temperature detector. The pressing mechanism 2 also includes an inlet pipe 24 and an outlet pipe 25. The inlet pipe 24 is located inside the inlet at the upper end of the jacket 23, and the outlet pipe 25 is located inside the outlet at the lower end of the jacket 23 (both the inlet pipe 24 and the outlet pipe 25 penetrate the cylinder wall of the outer shell 3). The pressing plate 26 is located inside the pressing cylinder 21. The upper end of the outer shell 3 is equipped with a hydraulic cylinder 4. The telescopic end of the hydraulic cylinder 4 passes through the upper side wall of the outer shell 3 and the upper side wall of the pressing cylinder 21 in sequence and is fixedly connected to the upper side of the pressing plate 26. The inlet of the hydraulic cylinder 4 is connected to the output port of an external hydraulic oil pump. The material door 5 at the upper end of the outer shell 3 and the pressing cylinder 21 is opened.The plant material to be extracted (such as citrus peel, petals, etc.) is placed into the pressing cylinder 21. The material door 5 is closed and locked with a door lock to ensure the device is airtight. An external hydraulic oil pump supplies oil to the hydraulic cylinder 4. The telescopic end of the hydraulic cylinder 4 pushes the pressing plate 26 downward (the outer arc surface of the pressing plate 26 fits against the inner wall of the pressing cylinder 21 to form a sealed pressing space). The pressing plate 26 squeezes the raw material, causing the plant cells to rupture and release essential oil. The mixture of essential oil and residue produced by pressing flows into the filter cylinder 22 below through the filter holes 211 (0.5-1mm in diameter) on the bottom wall of the pressing cylinder 21. At the same time, the control switch 8 is operated to start the motor 10. The output shaft of the motor 10 drives the gear 28 to rotate through the rotating shaft. The gear 28 meshes with the driven gear 27, causing the filter cylinder 22 to rotate. The rotation of the filter cylinder 22 generates centrifugal force, which further separates the essential oil and residue in the mixture. The essential oil, which has a lower density, gathers on the outside of the filter cylinder 22, while the residue (such as fiber and pulp) settles. The oil accumulates at the bottom of the filter cylinder 22, whose wall is a filter screen structure (precision 0.1-0.3mm). Combined with centrifugal rotation, the essential oil passes through the filter screen into the outer shell 3, and is finally discharged through the essential oil discharge pipe at the bottom of the outer shell 3 for collection by workers. The residue remains inside the filter cylinder 22. A jacket 23 is fitted outside the pressing cylinder 21, and a heating or cooling medium (such as water, steam, or heat transfer oil) is circulated through the inlet pipe 24 and outlet pipe 25. When extracting heat-sensitive essential oils (such as rose and jasmine), cold water is introduced to cool the oil and prevent its components from evaporating due to high temperatures. When extracting high-viscosity raw materials (such as resins), steam is introduced to heat the oil, reducing its viscosity and improving its fluidity. After extraction, the motor 10 and hydraulic cylinder 4 are turned off, the drain door 7 at the bottom of the outer shell is opened, and the bottom plate 6 (threaded connection) at the bottom of the filter cylinder 22 is rotated to collect and process the residue. The residue inside the pressing cylinder 21 can be processed by workers by opening the material door 5, facilitating the extraction of plant essential oils.
[0025] The working principle of the extraction device for essential oil processing provided by this utility model is as follows: Open the material door 5 at the upper end of the outer shell 3 and the pressing cylinder 21, place the plant material to be extracted (such as citrus peel, petals, etc.) into the pressing cylinder 21, close the material door 5 and lock it with a door lock to ensure the device is sealed. An external hydraulic oil pump supplies oil to the hydraulic cylinder 4, and the telescopic end of the hydraulic cylinder 4 pushes the pressing plate 26 downwards (the outer arc surface of the pressing plate 26 fits against the inner wall of the pressing cylinder 21, forming a sealed pressing space). The pressing plate 26 squeezes the raw material, causing the plant cells to rupture and release essential oils. The mixture of essential oils and residue produced by pressing flows into the filter cylinder 22 below through the filter holes 211 (0.5-1mm in diameter) on the bottom wall of the pressing cylinder 21. At the same time, the control switch 8 is operated to start the motor 10. The output shaft of the motor 10 drives the gear 28 to rotate through the rotating shaft. The gear 28 meshes with the driven gear 27, causing the filter cylinder 22 to rotate. The rotation of the filter cylinder 22 generates centrifugal force, further separating the essential oils from the residues in the mixture. Oil with lower density tends to accumulate on the outside of the filter cylinder 22, while residues (such as fibers and pulp) settle at the bottom. The filter cylinder 22 has a filter screen structure (0.1-0.3mm precision). Combined with centrifugal rotation, the essential oil passes through the filter screen into the outer shell 3, and is finally discharged through the essential oil discharge pipe at the bottom of the outer shell 3 for collection by workers. Residues remain inside the filter cylinder 22. The jacket 23 is fitted around the outside of the pressing cylinder 21, and a heating or cooling medium (such as water) is circulated through the inlet pipe 24 and the outlet pipe 25. When extracting heat-sensitive essential oils (such as rose and jasmine) using steam or heat transfer oil, cold water is introduced to cool the oil and prevent the essential oil components from evaporating due to high temperature. When extracting high-viscosity raw materials (such as resins), steam is introduced to heat the oil and reduce its viscosity, thereby increasing its fluidity. After extraction, the motor 10 and hydraulic cylinder 4 are turned off, the drain door 7 at the bottom of the outer shell is opened, and the bottom plate 6 (threaded connection) at the bottom of the filter cylinder 22 is rotated to collect and process the residue. The residue in the pressing cylinder 21 can be processed by workers by opening the material door 5.
[0026] It is worth noting that the pressing plate 26 disclosed in the above embodiments is a stainless steel pressing plate, the hydraulic cylinder 4 can be an HSG-K series, the motor 10 can be a Y2-90L-4 three-phase asynchronous motor, and the control switch 8 is provided with a corresponding control button for controlling its switch.
