Description

Technical Field

[0001] This utility model relates to the field of plant essential oil extraction, and in particular to an ultrasonic-assisted plant essential oil extraction device. Background Technology

[0002] Plant essential oils are widely recognized natural specialty chemicals, typically possessing unique aromas and physiological and even pharmacological effects. Their applications in the medical, health, daily chemical, and food industries are increasingly widespread, leading to a rapidly expanding market. However, current industrial extraction processes for plant essential oils generally face challenges such as low resource utilization efficiency, high energy consumption, and high costs. To address these issues, ultrasonic extraction devices are typically used. These devices utilize the strong cavitation effect generated by ultrasonic radiation pressure, along with mechanical vibration, high acceleration due to disturbance, emulsification, diffusion, fragmentation, and stirring effects. These multi-stage effects increase the frequency and speed of molecular motion, enhance solvent penetration, and thus accelerate the entry of essential oil components into the solvent, promoting extraction.

[0003] However, in existing ultrasonic extraction devices, the extraction of essential oils is limited by the attenuation of ultrasonic waves. The effective area of ​​ultrasonic action is a ring. If the diameter of the extraction tank is too large, an ultrasonic blank area will be formed, which will prevent the raw material around the tube wall from being cavitated by ultrasonic waves, resulting in incomplete extraction and affecting the extraction yield of essential oils.

[0004] Therefore, this utility model proposes an ultrasonic-assisted plant essential oil extraction device. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This utility model provides a technical solution for an ultrasonic-assisted plant essential oil extraction device: it includes an extraction vessel body 1, with a matching connecting flange 3 and an external connecting seat 2 fixedly connected to the upper and lower ends of the extraction vessel body 1, an inlet 4 opened on the top of the external connecting seat 2, an extraction chamber 5 inside the extraction vessel body 1, and an ultrasonic generating component 6 and an external buffer component 7 embedded inside the extraction vessel body 1.

[0022] The ultrasonic generating assembly 6 includes a transducer mechanism 8, a connecting bracket 9, an amplitude transformer 10, and a vibrating rod 11 connected sequentially from top to bottom. An auxiliary blade 12 is fixedly connected to the surface of the vibrating rod 11. The outer buffer assembly 7 includes an auxiliary cylinder 13 and a buffer plate 15. An outer connecting plate 14 is fixedly connected between the auxiliary cylinder 13 and the buffer plate 15. An auxiliary layer 17 is fixedly connected to the inner side of the auxiliary cylinder 13, and a buffer layer 16 is fixedly connected to the surface of the auxiliary cylinder 13.

[0023] like Figure 1-2 As shown, the bottom of the extraction chamber 5 is spherical and the top is cylindrical and vertical. The top is fixedly connected to the inner wall of the top of the extraction vessel body 1. The spherical extraction chamber 5 ensures that the injected raw material can fully contact the ultrasonic generator component 6.

[0024] The vibrating rod 11 is vertically positioned within the extraction chamber 5. The surface of the vibrating rod 11 is segmented with spiral sleeves distributed among auxiliary blades 12. The auxiliary blades 12 are semi-circular and staggered on the surface of the vibrating rod 11. The combination of the vibrating rod 11 and the auxiliary blades 12 promotes the extraction of the injected raw material in the extraction chamber 5. The spiral sleeves and auxiliary blades 12 effectively increase the contact area between the vibrating rod 11 and the raw material in the extraction chamber 5, thereby reducing the ultrasonic blank area, improving oscillation efficiency, and increasing the extraction rate.

[0025] During the extraction operation, the raw material is injected through the feed port 4, the ultrasonic generator 6 is activated, and ultrasonic waves are generated in the extraction vessel body 1 through the transducer 8 with the help of the vibrating rod 11. With the assistance of the auxiliary blades 12, the generated ultrasonic waves can produce strong cavitation effect, mechanical vibration, extremely high acceleration, emulsification, diffusion, crushing and stirring, which increases the frequency and speed of the movement of the material molecules and the solvent penetration force, thereby accelerating the entry of the beneficial substances of the drug into the solvent and promoting the extraction process.

[0026] like Figure 3 As shown, the auxiliary cylinder 13 is embedded in the extraction chamber 5 and fits against its inner wall. The auxiliary layer 17 is sleeved on the inner side of the auxiliary cylinder 13 and has a wave-shaped surface. At the same time, a micro vibration mechanism is embedded between the auxiliary layer 17 and the auxiliary cylinder 13. Two sets of buffer plates 15 are arranged in an arc shape and are located on both sides of the auxiliary cylinder 13. The buffer plates 15 are hollow and are located on both sides between the extraction chamber 5 and the extraction vessel body 1. The buffer layer 16 is arranged in an arc shape and fits against the two sides of the auxiliary cylinder 13. The auxiliary cylinder 13 and the auxiliary layer 17 on its inner side achieve the effect of assisting the contact between the raw material injected into the extraction chamber 5 and the ultrasonic generator 6. The buffer plate 15 and the buffer layer 16 reduce the vibration transmitted by the auxiliary cylinder 13.

[0027] When the injected raw material is subjected to ultrasonic extraction in the extraction chamber 5, the micro vibration mechanism built into the auxiliary cylinder 13 and the auxiliary layer 17 is activated to assist the injected raw material in vibrating and contacting the ultrasonic generator 6, ensuring the extraction efficiency of the ultrasonic generator 6 for the injected raw material. At the same time, when the auxiliary cylinder 13 is vibrating, the buffer plate 15 and the buffer layer 16 can reduce the vibration transmission generated by the auxiliary cylinder 13, ensuring the stability of the extraction vessel body 1.

[0028] The working principle of this utility model is as follows: When this device is in use, the basic ultrasonic extraction operation of the raw material is realized through the extraction chamber 5 and the ultrasonic generator 6. At the same time, the auxiliary layer 17 and the auxiliary blades 12 ensure that the raw material can effectively contact the ultrasonic waves, thereby reducing the ultrasonic blank area and improving the oscillation efficiency and extraction efficiency. The buffer plates 15 and the buffer layer 16 on both sides reduce the impact of vibration on the main body of the extraction vessel 1.

[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
