Description

Technical Field

[0001] This utility model relates to the field of essential oil extraction technology, specifically an essential oil extraction device. Background Technology

[0002] Essential oils, as natural extracts widely used in fragrances, medicine, and cosmetics, are experiencing increasing market demand. Traditional essential oil extraction methods mainly include distillation, pressing, and solvent extraction, with distillation being one of the most commonly used techniques due to its simplicity and wide applicability. Distillation extraction equipment typically consists of a heating system, a condensation system, and a separation system. The raw material is heated to volatilize the essential oil components, which are then condensed and separated to obtain pure essential oils. With technological advancements, essential oil extraction equipment is continuously being improved in terms of structural design and functional optimization, aiming to increase extraction efficiency, reduce energy consumption, and enhance product quality.

[0003] While existing essential oil extraction equipment meets market demand to some extent, it still has some shortcomings. One prominent issue is the limitation of the stirring method. Many devices use motor-driven stirrers to mix the raw materials. While this method achieves uniform mixing, it suffers from high energy consumption, complex equipment structure, and high maintenance costs. Furthermore, the stirring speed adjustment of motors is not flexible enough, making it difficult to precisely control the stirring according to the characteristics of different raw materials. This results in unstable extraction results, failing to meet the requirements for high-quality essential oil production. Therefore, developing a new, efficient, energy-saving, and flexible stirring mechanism has become an urgent problem to be solved in the field of essential oil extraction technology. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an essential oil extraction device that solves the problems of high energy consumption, complex structure, high maintenance costs, and inflexible adjustment in existing essential oil extraction devices that use motor-driven stirrers, thus affecting equipment stability and extraction effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an essential oil extraction device, comprising a distillation cylinder, an acceleration channel at the upper end of the distillation cylinder, a cylinder body at the upper end of the acceleration channel, a condenser tube connected to the outlet of the cylinder body, an oil-water separator at the other end of the condenser tube, a storage cylinder with a mesh-like bottom inside the distillation cylinder, a limiting plate horizontally connected to one side of the inner wall of the cylinder body, a turbine fan installed at the bottom of the other end of the limiting plate at the central axis of the cylinder body, a limiting shaft connected to the lower end of the turbine fan, and a stirrer connected to the limiting shaft passing through the cylinder body and the acceleration channel in sequence and located inside the storage cylinder.

[0006] Preferably, the inner diameter of the acceleration channel is smaller than the inner diameter of the distillation cylinder and the cylinder body.

[0007] Preferably, the bottom of the distillation cylinder is provided with an air inlet, and the inner bottom of the distillation cylinder is provided with an air guide hood communicating with the air inlet, and the air guide hood is located directly below the storage cylinder.

[0008] Preferably, an annular block is provided on the inner wall of the cylinder below the limiting plate, and an annular cavity is provided inside the annular block. A non-Newtonian fluid is provided in the cavity. An annular groove communicating with the cavity is provided on the lower part of the inner annular sidewall of the annular block. A sealing plate is rotatably arranged in the annular groove. One side of the limiting shaft is connected to the sealing plate by a horizontal connecting rod. A movable rod is connected to the outer annular sidewall of the sealing plate inside the cavity.

[0009] Preferably, a bolt rod is threaded through the upper part of one side of the cylinder, and the lower end of the bolt rod is connected to a movable shaft. The lower end of the movable shaft slides longitudinally through the upper part of the annular block and is located in the cavity and connected to an annular piston plate.

[0010] Preferably, the outer diameter of the annular piston plate is adapted to the inner diameter of the cavity, and the annular piston plate is located above the non-Newtonian fluid.

[0011] This invention provides an essential oil extraction device, which has the following advantages compared with the prior art: 1. This essential oil extraction device utilizes the acceleration effect of high-temperature steam in the acceleration channel to drive the turbine fan to rotate, which in turn drives the agitator to stir the raw materials in the storage cylinder. By utilizing the kinetic energy of steam, uniform stirring of the raw materials can be achieved without additional energy input. The rotation of the agitator ensures full contact between the raw materials and water vapor, accelerates the volatilization of essential oil components, and significantly improves the efficiency of essential oil extraction. This design not only simplifies the equipment structure and reduces energy consumption, but also improves the automation level and ease of operation of the entire extraction process.

[0012] 2. This essential oil extraction device introduces a non-Newtonian fluid as the control medium. A moving shaft drives an annular piston plate to compress or disperse the non-Newtonian fluid, thereby adjusting the speed of the stirrer. This unique control method allows for flexible adjustment of the stirring rate according to actual needs, ensuring optimal stirring results for raw materials at different stages. Compressing the non-Newtonian fluid increases resistance and slows the stirring speed, suitable for raw materials requiring gentle processing; dispersing the non-Newtonian fluid reduces resistance and accelerates the stirring speed, suitable for raw materials requiring rapid processing. This achieves refined management of the stirring rate, improves the equipment's adaptability to different raw materials and operational flexibility, and further optimizes the quality and yield of essential oil extraction.

[0015] 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.

[0016] Please see Figures 1-3 This utility model provides two technical solutions: Example 1

[0017] Please see Figures 1-2 In this embodiment of the present invention, an essential oil extraction device includes a distillation cylinder 1, an acceleration channel 2 is provided at the upper end of the distillation cylinder 1, a cylinder body 3 is provided at the upper end of the acceleration channel 2, a condenser 4 is connected to the outlet of the cylinder body 3, and an oil-water separator 5 is provided at the other end of the condenser 4.

[0018] Please see Figures 1-2 In this embodiment of the present invention, an air inlet 101 is provided at the bottom of the distillation cylinder 1, and an air guide shroud 102 communicating with the air inlet 101 is provided at the bottom inner side of the distillation cylinder 1. The air guide shroud 102 is located directly below the storage cylinder 6.

[0019] The raw material is placed into the storage cylinder 6, and then high-temperature steam is introduced into the air inlet 101. The steam is distributed from the air guide shroud 102 to the bottom of the storage cylinder 6, and then passes through the storage cylinder 6 to heat the raw material, so that the essential oil in the raw material turns into steam. Then the mixed steam enters the condenser tube 4 through the cylinder 3 for condensation. After condensation, it enters the oil-water separator 5 for oil-water separation, thereby completing the essential oil extraction operation.

[0020] Please see Figures 1-2In this embodiment of the present invention, a storage cylinder 6 with a mesh structure at the bottom is provided inside the distillation cylinder 1. A limiting plate 7 is horizontally connected to one side of the inner wall of the cylinder 3. A turbine fan 8 is installed at the bottom of the other end of the limiting plate 7 at the position of the central axis of the cylinder 3. A limiting shaft 9 is connected to the lower end of the turbine fan 8. The limiting shaft 9 passes through the cylinder 3 and the acceleration channel 2 in sequence and is connected to a stirrer 10 inside the storage cylinder 6.

[0021] Please see Figures 1-2 In this embodiment of the present invention, the inner diameter of the acceleration channel 2 is smaller than the inner diameter of the distillation cylinder 1 and the cylinder 3. According to Bernoulli's principle, during fluid flow, the pressure will decrease where the flow velocity increases. When the gas enters the small inner diameter acceleration channel 2 from the large inner diameter distillation cylinder 1, the flow velocity increases due to the decrease in cross-sectional area, resulting in a decrease in pressure. This pressure difference further promotes the gas to accelerate through the acceleration channel 2.

[0022] In this embodiment, when the steam passes through the small-diameter acceleration channel 2 from the large-diameter distillation cylinder 1, the steam will be accelerated in the acceleration channel 2 and then enter the cylinder 3. When it passes through the turbine fan 8, the turbine fan 8 will rotate under the action of the accelerated airflow, which will drive the stirrer 10 at the lower end of the limiting shaft 9 to rotate. The stirrer 10 can stir the raw material in the storage cylinder 6, so that the raw material can fully contact the water vapor.

[0023] Example 2, based on Example 1, adds a device to control the stirring rate of the raw materials, as follows: Please see Figures 2-3 In this embodiment of the present invention, an annular block 11 is provided on the inner wall of the cylinder 3 below the limiting plate 7. An annular cavity 12 is provided inside the annular block 11. A non-Newtonian fluid 13 is provided in the cavity 12. An annular groove 14 communicating with the inside of the cavity 12 is provided on the lower part of the inner annular sidewall of the annular block 11. A sealing plate 15 is rotatably provided in the annular groove 14. One side of the limiting shaft 9 is connected to the sealing plate 15 by a horizontal connecting rod 16. A moving rod 17 is connected to the outer annular sidewall of the sealing plate 15 inside the cavity 12.

[0024] Please see Figures 2-3 In this embodiment of the present invention, a bolt rod 18 is threaded through the upper part of one side of the cylinder 3. The lower end of the bolt rod 18 is connected to a movable shaft 19. The lower end of the movable shaft 19 slides longitudinally through the upper part of the annular block 11 and is located in the cavity 12 and is connected to an annular piston plate 20.

[0025] Please see Figures 2-3 In this embodiment of the present invention, the outer diameter of the annular piston plate 20 is adapted to the inner diameter of the cavity 12, and the annular piston plate 20 is located above the non-Newtonian fluid 13.

[0026] When the limiting shaft 9 rotates, it drives the connecting rod 16 to rotate. The connecting rod 16 causes the sealing plate 15 to rotate within the annular groove 14 on the annular block 11. The annular groove 14 drives the moving rod 17 to revolve. By rotating the bolt rod 18, the moving shaft 19 can be moved longitudinally, causing the annular piston plate 20 at the lower end of the moving shaft 19 to compress or disperse the non-Newtonian fluid 13 within the annular block 11. When the non-Newtonian fluid 13 is compressed, its viscosity increases, and the resistance of the moving rod 17 during its revolve increases. Conversely, the viscosity decreases, and the resistance of the moving rod 17 during its revolve decreases. This causes the stirring speed of the agitator 10 at the lower end of the limiting shaft 9 to slow down or speed up, thereby allowing the stirring rate of the agitator 10 on the raw materials to be adjusted according to the actual situation.

[0027] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
